Psychology I Final Exam Review Chapter 1: What is Psychology Psychology: Scientific study of behavior and mental process Behavior: any action that other people can observe or measure Cognitive Activities: Includes dreams, perceptions, thoughts Psychological construct: we cannot see, touch or measure but we know they exist i.e. emotions and feelings Types of Psychologists: Clinical (majority of psychologists are these), counseling, school, educational, developmental, experimental Chapter 1: What is Psychology History of Psychology and Contemporary Perspectives Psychology has its roots in Ancient Greece: Socrates used a method of introspection (looking within) Wilhelm Wundt: Founded structuralism (theory of psychology that was concerned with breaking consciousness into two parts: objective sensations, subjective feelings) William James: Wrote The Principles of Psychology, the first textbook. Founded functionalism (concerned with how mental processes help organisms adapt to environment) John B Watson: School of Behaviorism, defined psychology as the scientific study of observable behavior Gestalt School Freud and Psychoanalysis Biological Perspective: emphasizes the influence of biology on our behavior Evolutionary Perspective: Evolution of behavior and mental processes Cognitive Perspective: Emphasizes the role that thoughts play in determining behavior Humanistic Perspective: Stresses human capacity of self-fulfillment and importance of consciousness, self-awareness, and capacity to make choices Psychoanalytic: Stresses influence of unconscious on behavior. Modern perspective stresses conscious choice Learning Perspective: emphasizes effect of experience on behavior Sociocultural Perspective: Studies the influence of gender, ethnicity, culture, and socioeconomic status Chapter 2: Research Methods Psychology is closely related to natural sciences because the scientific method is used when conducting research 1. Form research Question 2. Form a Hypothesis 3. Test Hypothesis 4. Analyze the Results 5. Draw Conclusions 6. Replicate When conducting surveys, you must consider the population and sample size (random vs. stratified sample) When conducting experiments, a control group and experimental group must be used, independent and dependent variables identified Single blind vs. Double blind studies Utilize different types of observation (case study-Freud, naturalistic, longitudinal/cross sectional, laboratory) ETHICS: confidentiality, informed consent, deception (is it really necessary?) Chapter 3: Biology and Behavior Nervous System: consists of the central and peripheral systems. Neuron = nerve cell, consists of dendrites, axons, myelin sheath, and synapse Central nervous: spinal cord and brain Peripheral: Somatic (transmits messages to central nervous system) and Autonomic (regulates body’s vital functions) Within autonomic there are the sympathetic (prepares body for stressful event) and parasympathetic (restores body’s functions after event) Brain 3 parts: Hindbrain, Midbrain, and Forebrain Medulla: involved in vital functions such as heart rate, blood pressure, and breathing, located in hindbrain Cerebellum: involved in balance and coordination, located in hindbrain Thalamus: relay station for sensory info., located in forebrain Cerebrum: accounts for 70% of weight of brain Corpus Callosum: connects right and left hemispheres Chapter 3: Biology and Behavior Endocrine System: consists of glands that secrete hormones into bloodstream Pituitary gland: responsible for secreting hormones that effect behavior Thyroid gland: produces thyroxin which effects body’s metabolism Adrenal glands: produce adrenaline and noradrenaline; plays a part in emotions Testosterone and estrogen Heredity: transmission of characteristics from parents to offspring Consists of genes (basic building blocks) which are made of chromosomes Nature vs. Nurture debate Kinship studies reveal much about influence of heredity on traits Twin studies, adoptee studies, twins raised apart Chapter 4: Sensation and Perception Sensation: stimulation of sensory receptors and transmission of sensory info. To central nervous system. Absolute Threshold: Weakest amount of stimuli that can be sensed vs. Difference Threshold (minimum amount of difference that can be detected between two stimuli) Eye: consists of pupil, lens, retina, cornea, and optic nerve. Photoreceptors are neurons that are sensitive to light Rods are sensitive to only black and white, cones allow us to see in color (red, green, blue) Hearing: Ear canal Eardrum Hammer, anvil, stirrup Cochlea Auditory Nerve Smell (olfactory nerves, sends messages about odor to brain) Taste: sweet, salty, bitter and umami (savory) Vestibular: Tells you if you are upright without using eyes; balance Kinesthesis: informs people about the position and motion of their bodies Chapter 4: Sensation and Perception Closure: Tendency to perceive whole before individual parts Figure Ground Perception: Perception of figures against a background Proximity: perceiving items to be together because they are near each other Similarity: Tendency to group items that are similar together Continuity: Preference to see smooth continuous patterns Common fate: Things that move together belong together Stroboscopic Motion: illusion of movement Perceptual Constancies: Size, color, and brightness Chapter 5: Consciousness Meanings of Consciousness: Sensory Awareness (senses are activated), Direct Inner awareness (aware of what you are feeling), Sense of Self (“I”) Levels of Consciousness: Non-conscious (i.e. breathing), Unconscious (i.e. fears, hidden desires), Preconscious (i.e. memories), Conscious (i.e. thoughts) Altered States of Consciousness: Sense of self or world changes Sleep: Necessary to maintain brain function, reduce stress, reduce infection Circadian Rhythm: biological clock (tells you when to sleep and wake up) 5 Stages of Sleep Dream Theories (wish fulfillment, information processing) Sleep problems (Sleep apnea- trouble breathing, Insomnia- trouble going to sleep, Sleep Walking, Nightmares/Terrors, Narcolepsy) Meditation, Hypnosis, biofeedback Drugs Stimulants- increase activity of nervous system. Nicotine, Amphetimes (help you stay awake) Depressants- slow down activity of nervous system. Alcohol, Narcotics Hallucinogens- Produce hallucinations. Marijuana, LSD Chapter 6: Learning Classical Conditioning: When old response becomes attached to a new stimulus. Involves involuntary, reflexive behaviors. Elements of Classical Condition: NS, UCS, UCR, CS, CR Ex: Pavlov’s dogs salivate at the sound of a bell after they had been conditioned. Usually food should make a dog drool Taste Aversions: avoiding food that made you feel sick Extinction: Conditioned response disappears after conditioned stimulus is not presented Spontaneous Recovery: Conditioned Response occurs again after a period of time Generalization (reacting the same way to similar stimuli) vs. Discrimination (reacting only to the same stimuli) Flooding: exposure to harmless stimuli Systematic Desensitization: gradual exposure to harmless stimuli to extinguish fear I.e. Put into a room full of snakes to extinguish fear of snakes i.e. People are taught relaxation techniques when presented with the feared stimulus Counterconditioning: Presenting feared stimulus with something pleasant Giving someone a cookie as a snake gets closer to them Chapter 6: Learning Operant Conditioning: Form of learning based on consequences of actions. Voluntary response. Positive Reinforcement: Rewards Negative Reinforcement: Escape or avoid unpleasant behavior OR punishment to extinguish behavior I.e.: Starburst for raising hand I.e.: Giving into a whining child (escape); squirting your dog in the face with water when she steals a slipper (punish) Reinforcement schedules Continuous (behavior is reinforced all the time) vs. Partial (behavior is reinforced some of the time) Interval (time that elapses) vs. Ratio (# of time that behavior occurs) Primary reinforcers (satisfy biological need- food, water, sleep) vs. Secondary Reinforcers (learned value- coupons, grades) Shaping: Teaching complex behaviors in small steps Riding a bike, teaching a dog to drive Chapter 7: Memory 3 Kinds of Memory Episodic: Memory of specific events. Can include flashbulb memories (quick, vivid memories) Semantic: General Knowledge (i.e. facts learned in school) Implicit: Consists of skills or procedure (i.e. riding a bike, swimming) 3 Processes of Memory Encoding: Translate information into form that it can be stored Storage: Maintaining encoded information Visual codes (pictures) , Acoustic Codes (sounds), Semantic Codes (making sense of info.) Elaborative Rehearsal (making meaning), Maintenance Rehearsal (repeating over and over, not meaningful) Retrieval: Locating stored information and returning it to conscious thought Context dependent (place where memory was encoded) vs. State dependent (emotional state when memory was encoded) Chapter 7: Memory 3 Stages of Memory Sensory Memory: Immediate, initial recording of information that enters in through the senses. Iconic, Eidetic, and Echoic memory Short Term Memory: “Working Memory”. Primacy vs. Recency Effect Chunking Information only lasts a short time unless we transfer it to long term memory Long Term Memory Capacity is endless Steps must be taken in order for information to be stored properly into long term memory (maintenance rehearsal, elaborative rehearsal, associating pairs, chunking, etc.) Memories are reconstructed from bits and pieces of information Chapter 8/9: Thinking and Intelligence Thinking is the mental activity that is involved in the understanding, processing, and communicating of information. Problem Solving Convergent Thinking (facts) vs. Divergent Thinking (creativity) Reasoning Overconfidence: result of flimsy evidence, ignoring contradicting examples, and firm, unchanging beliefs Language is the communication of ideas through symbols that are arranged according to rules of grammar Intelligence can be defined as the abilities to learn from experience, think rationally, and to deal effectively with others Gardner’s Multiple Intelligences, IQ Tests
