Psychology I Final Exam Review

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
