PSYCHOLOGY IN ACTION: ANOMALISTIC PSYCHOLOGY Learning Objectives Issues to Consider Anomalistic psychology refers to experiences that do not fit in with conventional physical laws, for example, clairvoyance, telepathy, extra-sensory perception, and psychokinesis. These experiences cannot be explained by science and scientific principles and this area of study is known as parapsychology. In this chapter we will consider the theoretical and methodological issues in the study of anomalous behaviour as there is a great deal of controversy as to whether paranormal experiences really exist. We will also consider the factors that underpin anomalous experience including biological, cognitive, personality, the functions of paranormal beliefs and the role of self-deception, deception, superstition, and coincidence in paranormal experience. Finally, we will consider some fascinating examples of anomalous experience, psychic healing, out-of-body/near death experience, and psychic mediumship. On completion of this topic you should be familiar with the following. Use this list of learning objectives as a revision checklist. Cross-reference the objectives with the Specification. Theoretical and methodological issues in the study of anomalous experience Discuss issues of pseudoscience and scientific fraud. Critically consider controversies relating to Ganzfeld studies of ESP and studies of psychokinesis.

Issues of Pseudoscience Fill in the blanks. Pseudoscience refers to beliefs that are based on a body of knowledge or “evidence” that appears to be s____________ic but that, on closer inspection, does not adhere to scientific principles or methods. An example is parapsychological phemonena, such as mind reading. Pseudoscience is the opposite of science because it requires open-minded belief; it has failed to use many aspects of the scientific m__________d favoured by traditional science. The scientific method involves the manipulation of an ind_______________nt variable and measure of a dependent variable. All other variables need to be controlled, so that the independent variable is isolated as the only factor affecting the de____________nt variable. Pseudoscience does not employ rigorous controls. RESEARCH EVIDENCE FOR PARAPSYCHOLOGY BEING A PSEUDOSCIENCE Summarise the research evidence below. Ψ Mousseau (2003). What did his review of parapsychology research conclude? Ψ Self-citations. Why are these an issue? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 2 RESEARCH EVIDENCE AGAINST PARAPSYCHOLOGY BEING A PSEUDOSCIENCE Summarise the research evidence below. Ψ There are some parapsychology procedures that are scientific. Which research did use the experimental method? Ψ Conventional science is not always appropriate. Why? Issues of Scientific Fraud Fill in the blanks. Scientific fr______d involves the participant, the experimenter, or both, claiming phenomena that have not really happened! Research example: the case of Walter J. Levy Fill in the blanks. Levy (see A2 Level Psychology pages 652–653) was researching the psi (ESP) abilities of rats and gerbils, among other species. Mainly positive results were found and these seemed to be valid as the study controlled for humans affecting the recording of results as equ___________nt was used to do this. Levy’s associates—Kennedy, Davis, and Levin— identified the case as fraudulent when they noticed that Levy acted strangely near the recording equipment. Levy was seen “fiddling” with the recording equipment, which was not necessary as the co________________er recorded the results on a “paper-punched” readout. It was no coincidence that this tied with a string of “hits” being recorded on a number of occasions! Subsequently it was also discovered that the plug for the “misses” was not connected and so could not re_______d them! Levy’s associates set up another recording device, unbeknownst to him, which showed conclusively that the misses had not been recorded by the original recording equipment. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 3 Research example: project Alpha—James Randi Fill in the blanks. Randi (1983; see A2 Level Psychology page 653) set up Project Alpha to test if the researchers were fraudulent. He chose two participants who appeared to have psychokinetic and ESP powers, e.g. spoon be________g and te_____________hy. Randi instructed the researchers to put only one object on the table for the participants to bend (to test if the researchers would follow a set protocol). However, there were many objects on the table and each item was marked with a tag attached to it via a piece of string, and so this could easily be sw_________d by the participants when the experimenter was dist___________ed. Another trick involved the participants deliberately leaving the room last so that they could leave a wi__________w unlocked. They would then come back and bend all of the spoons, and then claim that they had done this via psychokinesis during the night. The te___________hy tasks involved the participants being given an envelope with a target drawing inside, which was “sealed” using two staples. The participants were left in the room alone with the envelope! It wasn’t that difficult to unpick and then replace the staples. The participants deliberately got some wrong as 100% accuracy would have been suspicious. This research shows how easily researchers can be fooled by fraudulent participants and the lack of sc__________ic rigour of the test pro______________es. Controversies Relating to Ganzfeld Studies of Extra-Sensory Perception Fill in the blanks. ESP stands for extra-se__________ry pe___________n, which refers to an ability to acquire knowledge and information without the use of our five main senses, for example, te___________hy, pre-cognition, and clai______________t abilities. The Ganzfeld procedure (Ganzfeld is German for “entire field”) involves participants being placed alone in a room. They then experience mild sensory de_____________n because halved ping-pong balls are placed over their eyes, a red light is shone into their face, and they wear headphones that play white noise so that they experience vi_________l and au___________y deprivation for around 30 minutes. Participants are commonly referred to as receivers because whilst they are being sensory deprived, a sender will choose from the pack of Zener cards and try mentally to send the shape to the re____________r. The receivers describe what they feel is on the card. The results are then calculated to see whether the correct answers deviate significantly from ch_____ce. Controversy 1: have early research findings been replicated? Fill in the blanks. Early research, e.g. Rhine and Pratt (1954) showed that certain individuals had extraordinarily high scores on ESP tasks; as high as 40% accuracy (with chance being at 20%). The controversy is whether these findings have been successfully re____________d. Some argue that the tightening of c_________ls and the introduction of Ganzfeld-type procedures have meant such high accuracy is no longer found. However, Parker and Brusewitz (2003) challenge this and identify six more case studies of people who score well above ch________e in ESP and related tasks. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 4 Controversy 2: can the choice of experimental design affect results? Fill in the blanks. The second controversy refers to whether a fo_______d-choice or a fr_____-response design is used. In a forced-choice design, the participant chooses from a pre-de_______________d set of answers (e.g. Zener cards). However, with a free-response design, participants must simply state what is being transmitted to them and so there is no knowledge of the possible answers, which avoids the issue that c____________t responses will be more likely using a forced-choice design because the targets are kn______n. Research shows ESP is significantly more likely to be supported when fixed rather than when free-response is used, which questions the va_________y of these findings as evidence for ESP. Controversy 3: can factors bring about positive results without being a case for ESP? Fill in the blanks. Honorton and the Psychophysical Research Laboratory have identified a four-factor model of “success in Ganzfeld” studies, which suggests that certain factors do b____s results in favour of supporting ESP. These four factors have been further research by Dalton (1997). Explain why the following factors bias results. Ψ Factor 1: prior experience: Ψ Factor 2: practice of a mental discipline like meditation: Ψ Factor 3: prior laboratory experience: Ψ Factor 4: feeling/perception preferences on a Myers–Briggs-type indicator: A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 5 These four factors raise controversy because they are co_______________g variables that may account for ESP and so if research does not control these four factors then cause and e________t cannot be established. Controversy 4: can the belief of the experimenter affect ESP results? Fill in the blanks. Smith (2003) found results are more likely to support ESP when the experimenters believe in the existence of psi phenomena than when the experimenters are sc____________l. This is known as the experimenter ex_____________y effect as the experimenters’ expectations affect the responses of the participants. Participants may try harder when being studied by those that believe in psi. Controversies solved? Autoganzfeld Fill in the blanks. An autoganzfeld testing system has helped to address the weaknesses of the traditional method as the system is au__________c and randomised by computer so this eliminates human error and ex______________er effects. The procedure is completely standardised and can be easily replicated. After Honorton and a range of colleagues ran a series of trials using the system, a review was conducted and the success rate was well above ch________e, at 33% (Bem & Honorton, 1994). Thus, this offers stronger support for ESP than previous research with even higher percentages because this research is well controlled and so we can be more confident in the va__________y of the evidence. Psychokinesis (Mind Over Matter) Fill in the blanks. Psychokinesis (PK) derives from the Greek words psyche, meaning “m____d”, and kinesis, which means “mo__________nt”. This occurs when the mind is able to affect matter, space, time, or energy in a way that cannot be explained by the current laws of physics. A common test of psychokinesis is spoon-bending. There are two main types of psychokinesis: 1. Macro-PK: the ability to affect objects that can be directly ob_________d (so the effect can be seen), e.g. affecting the throw of a die or spoon-bending. 2. Micro-PK: the ability to affect much smaller objects (like a random number generator). Therefore, the effects cannot be d____________ly observed so the researchers use statistics to see if the results are well above what would be expected by chance. Significantly less work has been done on PK than on ESP. Nevertheless, there are still controversies surrounding research into PK. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 6 Controversy 1: early research used dice in a potentially biased way Fill in the blanks. Early research tested whether participants could influence the throw of two d______e to achieve a cumulative score over 7. For significance 5 hits out of every 12 rolls needed to be successful as this is better than chance. J.B. Rhine obtained results that were significantly better than chance. However, he decided to check whether the dice were b________d by changing the cumulative score round to less than 7, and then to exactly 7. Above-chance performance was seen on all trials, indicating biased dice. Radin and Ferrari (1991) reviewed 148 experiments using a m_____a-an_________is and found only 69 studies of these did check to see if the dice were bi___________d. The results were still significant and so did support PK but not as strongly as when all of the studies were used. The controversy is that not all studies have checked whether the dice are biased and so this questions the va___________y of the evidence as support for PK. Another bias in early research is that participants used to be allowed to throw the dice from their hand, therefore they may have practised ways of throwing the dice to influence the la____________g and so findings would be due to this rather than PK, thus completely invalidating the research as evidence for PK. Controversy 2: potential experimenter effects Fill in the blanks. Potential experimenter effects have been tested out via anpsi—examining if animals have PK powers. The procedure involves an el_____________ic grille with half of it activated at any one time to test if the animal can use PK powers to “send” the electric current to the other half of the grille. Irwin and Watt (2007) report that there has been success using a range of species. A study using cockroaches found a significant effect but in the wrong direction as the cockroaches sat on the side that became electrified sig________________ly more than chance would suggest (Schmidt, 1970)! Exp__________________er effects may account for the findings as it has been suggested Schmidt might have disliked cockroaches and so used his own PK powers to influence which half was electrified, i.e. the side that the cockroaches were on. Whilst we cannot be sure if experimenter effects occurred or not this shows how difficult it is to research parapsychology as it is difficult to is___________e the participants’ PK powers from those of the experimenter.

Cognitive, Personality, and Biological Factors Underlying Anomalous Experience Cognitive factors Fill in the blanks. A cognitive factor that affects anomalous experience is the sheep–goat effect, which refers to whether a person is a be____________r or non-believer in the paranormal. Believers are “sh_______p” and non-believers “go______s”. RESEARCH EVIDENCE FOR COGNITIVE FACTORS Summarise the research evidence below. Ψ Sheep’s and goats’ recall of a demonstration of ESP. How did their recall differ? Ψ Sheep’s and goats’ recall of a séance. How did their recall differ? Ψ Cognitive biases and horoscopes. How are judgements of horoscopes biased? EVALUATION OF COGNITIVE FACTORS Summarise the evaluation point below. Ψ Natural experiments. What is the key weakness of this method? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 9 Personality factors Fill in the blanks. One such personality trait that may affect anomalous experience is fa_______sy proneness (FP) and another is ext__________________n. RESEARCH EVIDENCE FOR PERSONALITY FACTORS Summarise the research evidence below. Ψ Wilson and Barber’s (1983) research on FP personality types. How did they differ from controls? Ψ FP and UFO experience. What did Gow et al. (2001) find? Ψ Extraverts and PSI. What did Parra and Villaneuva (2003) find? RESEARCH EVIDENCE AGAINST PERSONALITY FACTORS Summarise the research evidence below. Ψ Why does Roberts (1997) question FP evidence? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 10 EVALUATION OF PERSONALITY FACTORS Summarise the evaluation points below. Ψ Cause and effect. Why can this not be established? Ψ Control groups. Why is the use of these a strength? Ψ Extraversion as a confounding variable. Is it a confounding variable or not? Ψ Sample bias. What is the bias? Ψ Researcher bias. How might this have biased results? Ψ Self-report. What are the weaknesses of self-report? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 11 Biological factors Fill in the blanks. Two key biology factors that may underpin paranormal experiences are temporal lobe l_____y and electro____________y, and both of these may be linked. RESEARCH EVIDENCE FOR BIOLOGICAL FACTORS Summarise the research evidence below. Ψ The Temporal Lobe Lability Hypothesis. What is this? Ψ Blackmore’s (1994, see A2 Level Psychology page 663) replication for a Horizon programme. What were the results of this? Ψ Electrohypersensitivity. How has this been linked to anomalous experiences? RESEARCH EVIDENCE AGAINST BIOLOGICAL FACTORS Summarise the research evidence below. Ψ Sleep paralysis. Why do Blackmore and Cox (2000) suggest this is more relevant than temporal lobe lability? Ψ Spanos et al. (1993). How does this study challenge temporal lobe lability? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 12 EVALUATION OF BIOLOGICAL FACTORS Summarise the evaluation points below. Ψ Cause and effect. Why are these not established? Ψ Lack of scientific evidence. Why is there a lack of evidence? Ψ Lack of understanding of electrohypersensitivity. Why is this an issue? Ψ Reductionist. Why are biological factors too simplistic? Functions of Paranormal and Related Beliefs, Including Their Cultural Significance Psychodynamic functions hypothesis Fill in the blanks. One reason suggested for why people hold these beliefs is based on psychodynamic psychology. The Psychodynamic Functions Hy___________sis suggests early trauma (e.g. abuse) can lead to a belief in the pa_____________al. Irwin (1992) suggests childhood trauma leads to childhood fa___________sy (e.g. high imagination, prone to fantasy play, etc.) as a coping mechanism and this means the trauma can be repressed into the un_______________us. This manifests itself as either a paranormal experience or a stronger belief in paranormal activities during adolescence and adulthood. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 13 RESEARCH EVIDENCE FOR PSYCHODYNAMIC FUNCTIONS Summarise the research evidence below. Ψ Lawrence et al. (1995). Does this support the Psychodynamic Functions Hypothesis? A lack of control as a result of childhood experience Fill in the blanks. The Psychodynamic Functions Hypothesis has been expanded to give a broader theory; the concept of co________ol, and whether this is internal (feel have control of life) or external (feel external factors have control) as suggested by Rotter (1954), has been added to the theory. External lo______s of c____________l is more closely associated with pa________________l belief and so Irwin (2005) now suggests that paranormal beliefs arise because of a lack of control brought about not just by childhood abuse/trauma but any childhood experience characterised by a lack of control (e.g. having older si____________gs, having authoritarian parents, moving house a lot). RESEARCH EVIDENCE FOR A LACK OF CONTROL Summarise the research evidence below. Ψ A negative correlation between belief in the paranormal and perceived childhood control. What evidence is there for this? Loneliness and insecure attachment Fill in the blanks. Rogers, Qualter, and Phelps (2007, see A2 Level Psychology page 666) proposed that lon___________ss and/or atta__________________nt style affected paranormal belief. Thus, paranormal experience may be a way of dealing with loneliness and childhood ins_________________y, in particular, the avoidant attachment style may be able to explain paranormal beliefs because it follows the Psychodynamic Functions Hypothesis idea that we ignore and avoid dealing with the tr______________ic events of childhood. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 14 RESEARCH EVIDENCE INTO LONELINESS AND INSECURE ATTACHMENT Summarise the research evidence below. Ψ Childhood trauma, loneliness, and attachment style. Which one most strongly predicts paranormal beliefs? EVALUATION OF RESEARCH ON LONELINESS AND INSECURE ATTACHMENT Summarise the evaluation points below. Ψ Self-report biases. How do these affect validity? Ψ Multi-factorial. How do we know paranormal belief is multi-factorial? Cultural significance Fill in the blanks. The functions of belief in the paranormal are culturally re_____________e, which means they differ across cultures. Therefore, one culture may perceive a paranormal activity to be that—paranormal—yet another may see it as a human-based skill. RESEARCH EVIDENCE INTO CULTURAL SIGNIFICANCE Summarise the research evidence below. Ψ Belief in a huge monster called marsalai in New Guinea (Jahoda, 1969). How did researchers interpret this? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 15 Ψ Sleep paralysis and paranormal experience. What is this and why is the experience of it culturally relative? Ψ Irwin (1993). What cultural differences in paranormal experience did this research find? Ψ Near-death experiences. How do these show the influence of culture? The Psychology of Deception and Self-deception, Superstition, and Coincidence RESEARCH EVIDENCE INTO DECEPTION The cases of scientific fraud covered previously are examples of deception. Summarise the research evidence below. Ψ Faith healers. What observation did Wiseman (2001) make? Ψ The Cottingley Fairies photographs. Why are these examples of deception? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 16 Ψ The use of trickery. How does this go undetected? Ψ Psychic surgery. What is this and what evidence is there of deception? Self-deception Fill in the blanks. Self-deception is when we mislead ourselves to accept as t_____e what is most likely fa_____e. Irwin (2002, see A2 Level Psychology page 671) suggests that many psychologists agree self-deception to be the acceptance of a belief in a self-serving way by people who have a motivation to believe in whatever is under investigation. RESEARCH EVIDENCE INTO SELF-DECEPTION Summarise the research evidence below. Ψ Traditional Paranormal Belief (TPB) and New Age Philosophy (NAP) scores and self-deception. Is there any relationship? EVALUATION OF RESEARCH INTO SELF-DECEPTION Summarise the evaluation points below. Ψ Difficult to study. Why is it difficult to study deception and self-deception? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 17 Ψ Cause and effect. Why can cause and effect not be established in the research on selfdeception? Ψ Sample bias. Why is the sample biased in research on self-deception? Superstition Fill in the blanks. Superstition is defined as a belief or notion that is not based on re____________n or kno____________________e that highlights the “significance” of some behaviour to the individual. RESEARCH EVIDENCE INTO SUPERSTITION Fill in the blanks. Skinner’s view of superstition Skinner’s theory of op________________nt conditioning states that learning is based on the co_____________________es of behaviour. In general terms, we are more likely to repeat a behaviour if it is positively rei______________ed and less likely to repeat a behaviour if it is pu_________________d. One of the main assumptions of behaviourism is that general laws govern all behaviour (e.g. rewards), irrespective of species. Therefore, Skinner (1948, see A2 Level Psychology page 672) studied sup________________on in pigeons. Eight hungry pigeons were placed in their own Skinner boxes for just a few minutes per day, where they received food pellets every 15 seconds. This procedure lasted for several days and towards the end of this, the length of time between each delivery of pellets increased. Six of the eight pigeons began to show strangely re_______________e behaviours in between the delivery of food pellets. These included head tossing, pendulum-type swinging of the head, ho_____________g, and turning in an anti-clockwise circle. These behaviours had not been seen prior to the study and they were not performed once the food was presented to them. Thus, Skinner concluded that these behaviours were a form of su_________________on. The pigeons performed the behaviours as if the delivery of food depended on them. Thus, superstitions develop when we learn that behaving in a certain way will be re_________________ed. This is a form of maladaptive learning because in reality the behaviour has nothing to do with the reward. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 18 EVALUATION OF RESEARCH INTO SUPERSTITION Summarise the evaluation points below. Ψ Experimental support. Why is this a strength? Ψ Rewards are not always clear. Why not? Ψ Extrapolation. How does this question the behavioural approach? Ψ Ignores cognition. Why is this a key weakness? Perceptual and memory errors Fill in the blanks. Jahoda (1969) suggests that superstitions are formed because of errors or faults in our perceptual and m______________y systems. For example, “selective forgetting” means we remember only su__________________n-confirming thoughts and behaviours. Lehmann’s (1898) study of séances supports the fact there can be errors in our pe________________al and memory systems. The participants were asked to pick a line from a book. He then organised the séance so that there was a blackboard just underneath a red light with some unintelligible wr_____________g on it. The light was used because it is very difficult to observe much under this light, so anything that might be seen by a person at a séance would be an error in encoding and processing of information. Participants identified the unintelligible writing as the line they had chosen and so errors were confirmed. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 19 EVALUATION OF PERCEPTUAL AND MEMORY ERRORS Summarise the evaluation points below. Ψ Artificiality of the research means problems with demand characteristics. Why might demand characteristics have been guessed? Ψ Self-deception may be more valid. Why? Superstitions and the unconscious Fill in the blanks. Freud (1901) explains superstitions through un________________s mechanisms. Unconscious fears and desires drive our behaviour. Freud believed that superstitions are a form of pro_________________n whereby the threats from these unconscious thoughts are dealt with by attaching them to things in the outside world. One of Freud’s examples starts with a person having a cruel thought about someone they care a lot about. This causes g______lt and an expectation of punishment. This hidden conflict manifests in the conscious as a su____________n that misfortune can be avoided if a particular set of behavioural patterns are stuck to. EVALUATION OF SUPERSTITIONS AND THE UNCONSCIOUS Summarise the evaluation points below. Ψ Unverifiable and unfalsifiable. Why can the theory not be verified or falsified? Ψ Lacks scientific validity. Why is this limited? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 20 Contemporary ideas and research on superstition Fill in the blanks. Contemporary research has expanded upon early work into faulty cognitive pro________________g. Lindemann and Arnio (2006) categorised participants into intuitive thinkers who tend to “trust their h__________es” and therefore use little reasoning and an_____________l thinkers who tend to “have explainable reasons for decisions”. 239 Finnish volunteers completed a battery of questionnaires aimed to test their superstitious beliefs, analytical thinking, and intuitive thinking. Roughly half of the sample were superstitious and the other half sceptics. The findings clearly showed that the superstitious participants relied much more on int___________e thinking than the sceptics and much less on analytical thinking in general decision making. They concluded that superstition can be explained using dual-coding pro____________es. The dual-processing refers to the fact we all process intuitively and analytically it is just that in superstitious people they process more intuitively when it comes to strange phenomena. EVALUATION OF CONTEMPORARY IDEAS AND RESEARCH ON SUPERSTITION Summarise the evaluation points below. Ψ Cause and effect. Why is it difficult to establish cause and effect? Ψ Self-report criticisms. Why might questionnaires not be the best method to test out processing? Ψ Reductionism. Why is the classification into superstitious or sceptics too simplistic? Coincidence Fill in the blanks. Psychologists are obviously interested in coincidences because many anomalistic experiences are based on “strange occurrences”. But how many are simply coincidences that can be explained by the laws of pro__________ity? So if coincidence has the probability of occurring to everyone in one million people per day, and the UK has a population of 61 million then 61 coincidences should happen per day, e.g. somebody ringing you just as you are thinking about them could lead you to think you have pre-co_______________e power. Many of these may be seen as being anomalistic in nature when it is simply what should happen by ch______________ce! A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 21 Coincidence and belief in paranormal activity Fill in the blanks. Blackmore and Troscianko (1985) conducted a classic study into the link between belief in the paranormal and coincidences and probability. They ran a series of experiments testing out the beliefs and pro____________y judgements of sheep (believers in psi) and goats (non-believers in psi). They found that sheep are more likely to see a coincidence as being something “out of the ordinary” because they are more likely to ov_____________k probability explanations for events in favour of anomalistic explanations. The sample for this research was 50 school girls so it lacks generalisability. However, a second sample of 100 volunteers (aged 12–67) were tested on their understanding of probability (results happening by chance) and the same results were found, that is “sheep” overlook probability and prefer “coi__________________ce” as an explanation. FIND OUT FOR YOURSELF: Make up a case study using a number of the different factors to illustrate who is most likely to experience paranormal phenomena. CONCLUSIONS—SO WHAT DOES THIS MEAN?

Research into Psychic Healing Fill in the blanks Psychic healing refers to the passing of some form of en_________gy from one person to another living being with the aim of treating the individual. This can be the laying of hands on an individual or through prayer. There are many anecdotal accounts about how healers have performed “mi_____________s” and cured people of a variety of ailments. Is this reliable or valid evidence? Scientific research requires randomised and d____________ebl_____d trials; that is, participants have an eq_____l chance of being in the healing or non-healing group and do not know which condition they are in. The doctors who examine the participants to see if their condition has improved also do not know who had healing or non-healing. RESEARCH EVIDENCE INTO PSYCHIC HEALING Summarise the research evidence below. Ψ Prayer healing. What evidence did Byrd (1998) find of this? Ψ Distant healing. Why is this a completely double-blind study? Ψ Abbott et al. (2001). Why does this study not support the use of healing in chronic pain sufferers? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 23 EVALUATION OF RESEARCH INTO PSYCHIC HEALING Summarise the evaluation points below. Ψ Double-blind design. Why is this design needed? Ψ Placebo effect. How might this explain the research findings? Ψ Confounding variables. How might these reduce validity? Ψ Contradictory findings. Which findings are contradictory? Research into out-of-body experiences Fill in the blanks. An out-of-body experience (OoBE) is said to occur when individuals believe that they have had a sensation of fl_________g out of their own body and being able to see their own body and the environment surrounding it. Very little research has tested the va___________y of OoBEs due to the obvious problem of the impossibility of testing the truth of self-re_____rt. Instead, research has focused on common characteristics across OoBEs. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 24 RESEARCH EVIDENCE INTO OUT-OF-BODY EXPERIENCES Summarise the research evidence below. Ψ Common characteristics of OoBEs. What are these, according to Alvarado (2000)? Ψ Irwin and Watt (2007). What further characteristics did they find? EVALUATION OF RESEARCH INTO OUT-OF-BODY EXPERIENCES Summarise the evaluation point below. Ψ Self-report criticisms. What are these criticisms? Research into near-death experiences Fill in the blanks. Generally, a near-death experience (NDE) is the perception reported by someone who was cli______________ly dead but revived or nearly died (this is the crucial difference between this and out-of-body experiences—the latter can occur in non-life threatening situations). RESEARCH EVIDENCE FOR NEAR-DEATH EXPERIENCES Summarise the research evidence below. Ψ Themes common to NDEs. What did Moody (1975) identify as common themes? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 25 Ψ Five stages of an NDE. What are these? Ψ Differences between NDE experients and a control non-NDE group. What did van Lommel et al. (2001) find? Ψ Physiological differences. Did Parnia et al. (2001) find any physiological difference between the NDE group and other survivors? Ψ Greyson’s (2003) research. What differences did this study find between an NDE group and a control group? EVALUATION OF RESEARCH INTO NEAR-DEATH EXPERIENCES Summarise the evaluation points below. Ψ Prospective not retrospective. Which study took a prospective approach and why is this a strength? Ψ Self-report. Why is this a weakness? A2 Level Psychology Workbook.

What cannot be established from correlational data? Research into psychic mediumship Fill in the blanks. Psychic mediumship refers to a type of relationship that a living person says they have with sp_____________s. Mediums tend to claim that they can communicate with spirits and pass on me__________________es to loved ones “left behind” in the “earthly” world. It is practised as part of many religions across the globe. There are many hypotheses about mediumship, ranging from the survival hypothesis (i.e. our spirit survives after death and can communicate) to the Sceptical Hy_________________is (which predicts that the mediums’ messages are so general that they can apply to anyone). RESEARCH EVIDENCE INTO PSYCHIC MEDIUMSHIP Summarise the research evidence below. Ψ The Sceptical Hypothesis. Why did Robertson and Roy’s (2001; 2004) research reject this? Ψ Robertson and Roy’s (2004) follow-up study. What did this find? A2 Level Psychology Workbook. Copyright © 2009 Psychology Press ANOMALISTIC PSYCHOLOGY 27 Ψ Sensory leakage. How did O’Keeffe and Wiseman (2005) control for this and why did this lead them to accept the Sceptical Hypothesis? EVALUATION OF RESEARCH INTO PSYCHIC MEDIUMSHIP Summarise the evaluation points below. Ψ Lack of standardisation. What is the lack of standardisation? Ψ Participant effects. How can these limit validity? FIND OUT FOR YOURSELF: Conduct research into one or more of the above phenomena. How do your findings compare to those found in the above psychological research? Refer back to the principles of scientific research from the introduction to this topic. Does the research meet or fail to meet these? CONCLUSIONS—SO WHAT DOES THIS MEAN? Answer the following questions in your conclusions: • Why is it difficult to research OoBEs or NDEs? • How has some research taken a more scientific approach? Using this in the exam Outline and evaluate research into psychic healing, out-of-body and/or near-death experience, and psychic mediumship. A2 Level Psychology Workbook. Copyright © 2009 Psychology Press (25 marks) ANOMALISTIC PSYCHOLOGY 28 Example Essay Plan (a) Outline issues of pseudoscience and scientific fraud. (9 marks) (b) Outline and critically evaluate findings from Ganzfeld studies. (15 marks) The marking is broken down into three sets of criteria, AO1, AO2, and AO3. In this question, part (a) is AO1 and part (b) is AO2/AO3. AO1 (9 marks) Outline reasons why anomalistic psychology may be seen as a pseudoscience and describe the examples of scientific fraud in some detail. AO2 (12 marks) Discuss the weaknesses of the original Ganzfeld studies and the improvements of the autoganzfeld testing system. AO3 (4 marks) A full consideration of the scientific weaknesses of the studies will achieve the AO3 marks. So the essay could be structured in the following way. Part (a) Explain why parapsychology is considered by many to be a pseudoscience and give examples of pseudoscience and scientific fraud. Outline evidence such as Mousseau’s (2003) findings that parapsychology uses the experimental method less than does mainstream science. Describe what scientific fraud means and use the cases of Walter J. Levy and Randi’s (1983) Project Alpha as evidence. Evaluate that these are just case studies and so cannot be said to be representative of all research into parapsychology. Describe Levy’s deliberate fraud and the poor methodology employed in the Project Alpha research. Certainly the fact that the participants could so easily defraud the researchers in the Project Alpha research shows the lack of scientific rigour of the test procedures. Part (b) Discuss the controversies of the technique such as the issue of replication and the effect of the experimental design, i.e. whether a forced-choice or a free-response design is used. Consider the confounding variables that limit internal validity. Also discuss whether factors such as prior experience, practice of a mental discipline like meditation, prior laboratory experience, and feeling/perception preferences on a Myers–Briggs-type indicator are confounding variables that may account for ESP, and so if research does not control these four factors then cause and effect cannot be established. Also discuss the issue of the experimenter expectancy effect. Assess how well the autoganzfeld testing system has addressed the weaknesses of the traditional method and use Bem and Honorton’s (1994) research as evidence. A2 Level Psychology Workbook.
