Psychological Science Develops
Behaviorists Ivan Pavlov a Russian Physiologist, James Watson and Skinner were all instrumental in developing the science of psychology and emphasized behavior instead of mind or mental thoughts. From 1920 to 1960, psychology in the US was heavily oriented towards behaviorism. Watson, a professor at Johns Hopkins said that psychologists should ignore mental events Dismissed introspection, defined psychology as “scientific study of observable behavior.” Watson baby Albert, Skinner superstitious pigeon. Science rooted in observation 20’s-60’s Which of the following approaches to psychology emphasizes observable responses over inner experiences when accounting for behavior? (AP94) (A) Behaviorist (B) Cognitive (C) Existentialist (D) Psychodynamic (E) Structuralist 1 66. Early behaviorists believed that psychology should not focus on “the mind” because “the mind” is (AP04) (A)Too complex (B)Genetically determined (C)Largely unconscious (D)Unobservable (E)Environmentally determined 2 or John B. Watson was a pioneer in which of the following perspectives of psychology? (AP04) (A)Biological (B)Functionalism (C)Psychoanalytic (D)Structuralism (E)Behaviorism Skinner ( ) Watson ( ) Watson and later Skinner emphasized the study of overt behavior as the subject matter of scientific psychology.

Survey Random Sampling
If the survey sample is biased, its results are not valid Important to avoid sampling errors. Watch out for convenience samples. 2 16. Drawing a random sample of people from a town for an interview study of social attitudes ensures that (AP99) (A) Each person in town has the same probability of being chosen for the study (B) An equal number of males and females are selected for interviews (C) The study includes at least some respondents from every social class in town (D) The study will uncover widely differing social attitudes among the respondents (E) The sample will be large enough even though some people may refuse to be interviewed If each member of a population has an equal chance of inclusion into a sample, it is called a random sample (unbiased). The fastest way to know about the marble color ratio is to blindly transfer a few into a smaller jar and count them.

Independent Variable IV
An independent variable is a factor manipulated by the experimenter. The effect of the independent variable is the focus of the study. For example, when examining the effects of breast feeding upon intelligence, breast feeding is the independent variable. IV "I" am the experimenter, so "I" manipulate the variables. Questions refer to the following study. A student hypothesizes that high school student’s consuming different flavors of a drink before a spelling test will perform differently.

FAQ Q1. Can laboratory experiments illuminate everyday life?
Q2. Does behavior depend on one’s culture and gender? Q3. Why do psychologists study animals, and is it ethical to experiment on animals? Preview Question 12: Can laboratory experiments illuminate everyday life? Ans: Artificial laboratory conditions are created to study behavior in simplistic terms. The goal is to find underlying principles that govern behavior. Simplified reality, test theoretical principles Preview Question 13: Does behavior depend on one’s culture and gender? Ans: Even when specific attitudes and behaviors vary across cultures, as they often do, the underlying processes are much the same. Biology determines our sex, and culture further bends the genders. However, in many ways woman and man are similarly human. Preview Question 14: Why do psychologists study animals, and is it ethical to experiment on animals? Ans: Studying animals gives us the understanding of many behaviors that may have common biology across animals and humans. From animal studies, we have gained insights to devastating and fatal diseases. All researchers who deal with animal research are required to follow ethical guidelines in caring for these animals. Animals used in 7-8% of psych research 2 30. According to the ethical guidelines set by the American Psychological Association (APA), which of the following is true of psychological research in which animals are used as subjects? (AP94) (A) It must not involve the use of surgical procedures. (B) It is no longer permitted by the APA without special authorization. (C) It should conform to all APA ethical guidelines for animal research. (D) It must be limited to investigations that use correlational procedures. (E) It may not be conducted by psychologists who do not have a license.

Myelin sheath Specialized Glial cells Acts as an electrical insulator
Not present on all cells When present increases the speed of neural signals down the axon. Key words: myelin sheath; action potentials; axon Charge actually moves along outside of the myelin, the signal travels faster. Allows Neuron to conserve energy because Na+ and K+ ions can only enter at the nodes of Ranvier and it requires less energy for Na and K pumps to reestablish resting gradient (biopsych pg 69) Interesting facts: - The myelin sheath is NOT a part of the axon. The myelin sheath is actually formed of glial cells (oligodendricytes and Schwann cells) that wrap around the axon. - You may have often heard the brain referred to as either white matter or gray matter. The myelin sheath appears white in nature. Hence, the term white matter refers to areas of the brain that are myelinated. Gray matter refers to areas of the brain that are unmyelinated. - When you accidentally cut yourself, you often visually notice that you've cut yourself before you actually feel any pain from the cut. The reason for this is that visual information uses myelinated axons; whereas, pain information uses unmyelinated axons. - The loss of myelin is a significant factor in the disease multiple sclerosis (MS). When myelin is lost, the high-speed transmission of information is slowed down or blocked completely, which could lead the person with the inability to walk, write or speak. 3 67. The primary effect of the myelin sheath is to (AP94) (A) Increase the velocity of conduction of the action potential along the axon (B) Increase the velocity of conduction of the action potential across the synapse (C) Facilitate the incoming stimulus signals at sensory receptors (D) Reduce the amount of unused neurotransmitter in the synaptic cleft (E) Protect the terminal buttons of the neuron from destruction by enzymes Myelin Sheath

(AP04) (A) Calcium and sodium (B) Sodium and potassium (C) Potassium and calcium (D) Chloride and calcium (E) Chloride and sodium
15
Threshold Threshold: Each neuron receives excitatory and inhibitory signals from many neurons. When the excitatory signals minus the inhibitory signals exceed a minimum intensity (threshold) the neuron fires an action potential. About -65 mv for many neurons (biopsychology p 62) Threshold: (minimum stimulation) Each neuron receives depolarizing and hyperpolarizing currents from many neurons. When the depolarizing current (positive ions) minus the hyperpolarizing current (negative ions) exceed minimum intensity (threshold) the neuron fires an action potential. 3 92. Which of the following occurs when a neuron is stimulated to its threshold? (A) The movement of sodium and potassium ions across the membrane creates an action potential. (AP99) (B) The neuron hyperpolarizes. (C) Neurotransmitters are released from the dendrites. (D) The absolute refractory period of the neuron prevents it from responding. (E) The neuron's equilibrium potential is reached.
16
Action Potential Properties
All-or-None Response: A strong stimulus can trigger more neurons to fire, and to fire more often, but it does not affect the action potentials strength or speed. Intensity of an action potential remains the same throughout the length of the axon. Either it fires or it does not Toilet flushing 3 5. Which of the following correctly describes the firing of neurons? (AP94) (A) A protoplasmic transfer of ions (B) A finely graded response (C) An all-or-none response (D) An osmotic process (E) A symbiotic function

Brain Stem The Thalamus is the brain’s sensory switchboard, located on top of the brainstem. It directs messages to the sensory areas in the cortex and transmits replies to the cerebellum and medulla. The thalamus processes information for all of the following senses EXCEPT (AP99) (A) Smell (B) Hearing (C) Taste (D) Vision In The Tangled Wing: Biological Restraints on the Human Spirit (1982), Melvin Konner calls the thalamus "the major way station of incoming sensation." In What Makes You Tick?, Czerner explains that the thalamus "is the gateway for virtually all of your sensations and directs impulses generated by each of your sensory neurons to its appropriate area in the cortex." For example, the thalamus directs visual information to the primary visual cortex, which we will discuss later in this narrative. In the photograph to the left (image links to source), you can see that the thalami occupy a central location among the subcortical nuclei. As previously noted, the thalami are actually two mirror-image ovoid masses that occupy each lateral wall of the third ventricle. This image is from John A. Beal of the Louisiana State University. The thalami are of primary importance in relaying messages from subcortical nuclei to the neocortex. The thalami are integral to what we will call cortical-subcortical circuits, which we will discuss at length in Part 3 of MyBrainNotes.com. These circuits possibly shift, in certain situations, into what I call autonomous processing mode whereby one circuit supports cognitive processing while another separate circuit supports more automatic processing and behavior, what we would call compulsions. Building on information in Parts 1 and 2, we extensively discuss the neurocircuitry of obsessions and compulsions in Part 3 of MyBrainNotes.com.

Thresholds Absolute Threshold: Minimum stimulation needed to detect a particular stimulus 50% of the time. Proportion of “Yes” Responses Stimulus Intensity (lumens) Preview Question 1: What is an absolute threshold, and are we influenced by stimuli below it? Proportion or percent Below the curve is subliminal Robert Cialdini illustrates the principle for sales. Assume that a man wants to buy a three-piece suit and a sweater. If you were the salesperson, which should you show him first in order to get him to spend the most money? You might think it best to sell the sweater first. Having spent a lot on a suit, the customer might be reluctant to spend more on a sweater. However, sales motivation analysts suggest the opposite. Sell the suit first because the additional cost of the sweater will not be so readily noticed. If the man has just paid $500 for a suit, an additional $75 for a sweater will not seem excessive. The same applies to other accessories, such as a shirt or shoes. As a rule, people will almost always pay more for accessories if they buy them after rather than before a more expensive purchase. The same principle holds for the purchase of accessories on a new car. After paying $32,000 for the car, the customer will hardly notice $700 for a sound system to go with it. The trick, of course, is to mention these accessories independently so that each addition will seem negligible in comparison to the much larger commitment already made. Cialdini, R. B. (2001). Influence: Science and practice (4th ed.). Boston: Allyn & Bacon.

Why Does the “Absolute” Threshold Vary? - Signal Detection
Sensitivity: Intensity of the signal. Capacity of sensory systems. Amount of background stimulation, or “noise.” Response criterion reflects one’s willingness to respond to a stimulus. Influenced by motivation and expectancies. Not meyers Important in psych,…jobs that require attention , air traffic controllers etc. When Jason practices the drums, he tends not to hear the phone. Today he is expecting a call from a record producer and answers the phone each time it rings even when he is practicing the drums. Which of the following explains why Jason hears the phone today? (AP04) (A) Weber’s law (B) Accommodation (C) Frequency theory (D) Signal detection theory (E) Harmonics

Judging Differences Between Stimuli
Difference Threshold or Just-Noticeable Difference (JND) JND = Smallest detectable difference in stimulus energy. JND determined by two factors: How much of a stimulus was there to begin with? Which sense is being stimulated? Add 1 oz to 10 oz, and you will probably detect it. Add 1 oz to 100 oz, and you will probably not detect it. The minimum intensity at which a stimulus can be detected at least 50 percent of the time is known as the (AP04) (A) Visual cliff (B) Just noticeable difference (C) Perceptual set (D) Receptor potential (E) Absolute threshold

Sensory Adaptation Diminished sensitivity as a consequence of constant stimulation. Preview Question 3: What function does sensory adaptation serve? In house with smell, you don’t notice, clothes rubbing skin, shoes, band aids Diminishing sensitivity to unchanging stimuli 12 1. The longer an individual is exposed to a strong odor, the less aware of the odor the individual becomes. This phenomenon is know as sensory (AP04) (A) Acuity (B) Adaption (C) Awareness (D) Reception (E) Overload Put a band aid on your arm and after awhile you don’t sense it.

The Lens Lens: Transparent structure behind the pupil that changes shape to focus images on the retina. Accommodation: The process by which the eye’s lens changes shape to help focus near or far objects on the retina. The change in the curvature of the lens that enables the eye to focus on objects at various distances is called (AP94) (A) Accommodation (B) Adaptation (C) Conduction (D) Convergence (E) Consonance
52
Retina Retina: The light-sensitive inner surface of the eye, containing receptor rods and cones in addition to layers of other neurons (bipolar, ganglion cells) that process visual information. When struck by light energy, cones and rods in the retina generate neural signals that then activate the (AP99) (A) Parietal lobe (B) Ganglion cells (C) Bipolar cells (D) ciliary muscle (E) Optic nerve fibers
53
Optic Nerve, Blind Spot & Fovea
Optic nerve: Carries neural impulses from the eye to the brain. Blind Spot: Point where the optic nerve leaves the eye because there are no receptor cells located there. Fovea: Central point in the retina around which the eye’s cones cluster. The place in the retina where the optic nerve exits to the brain is called the (AP94) (A) Lens (B) Sclera (C) Fovea (D) Blind spot (E) Aqueous humor
54
Retina’s Reaction to Light- Receptors
Rods peripheral retina detect black, white and gray twilight or low light Cones near center of retina fine detail and color vision daylight or well-lit conditions There are approximately 125 million rods located outside the fovea which code information about light and dark. There are approximately 6 million cones, mostly located in the fovea, which code information about light, dark, and color. Role of rods and cones differ. They contain photopigments – chemicals that respond to light. Light triggers action potentials in photoreceptors (rods and cones) by breaking down photopigments. It takes time for photpigments to regenerate… dark adaptation. 1. Rods are largely responsible for peripheral vision because of their location. 2. Rods are hundreds of times more sensitive to light, therefore, they play a more important role in vision in dim light. 3. Rods produce images that are perceived with less visual acuity than do cones. 4. Rods do not detect color as do cones. 20 min to fully adapt to darkness Which of the following is a possible reason why cats can see better at night that can humans? (AP04) (A) Cats have a higher proportion of rods to cones (B) Cat’s pupils can contract to a smaller opening (C) Cats have a smaller blind spot (D) Cats have a larger optic nerve tract (E) The visual cortex of cats is located farther forward in the cortex

Color Blindness Genetic disorder in which people are blind to green or red colors. This supports the Trichromatic theory. Monochromatic – one color Dichromatic – two color Tricromatic – three color (neitz) Dogs have limited dichromatic vision Most common in men, it is a sex linked trait Some 10 million American men—fully 7 percent of the male population—either cannot distinguish red from green, or see red and green differently from most people. This is the commonest form of color blindness, but it affects only .4 percent of women. More than 95 percent of all variations in human color vision involve the red and green receptors in men's eyes. It is very rare for anyone—male or female—to be "blind" to the blue end of the spectrum. Nathans provided a genetic explanation for this phenomenon. He showed that the gene coding for the blue receptor lies on chromosome 7, which is shared equally by men and women, and that this gene does not have any neighbor whose DNA sequence is similar. Blue color blindness is caused by a simple mutation in this gene. The most common form of color blindness is related to deficiencies in the (AP94) (A) blue-yellow system (B) red-green system (C) Process of visual summation (D) Bipolar cells (E) Secretion of rhodopsin Ishihara Test

Opponent Process Theory
Hering proposed that we process four primary colors combined in pairs of red-green, blue-yellow, and black-white. Proposed because of problems with Young Helmholtz. Mix red and green and get yellow, but red and green color blinds often see yellow Yellow appears as a pure color not a mix like purple. The retina processes info according to Young Helmholtz and the information is further processed by opponent processes cells in route to the visual cortex If Carmelita stares at a red spot for one minute and then shifts her gaze to a white piece of paper, she is likely to experience an afterimage that is (AP94) (A) Green (B) Red (C) Blue (D) Violet (E) Black

Pavlov’s Experiments Before conditioning, food (Unconditioned Stimulus, US) produces salivation (Unconditioned Response, UR). However, the tone (neutral stimulus) does not. Preview Question 3: How does a neutral stimulus become a CS, and what are the processes of acquisition, extinction, spontaneous recovery, generalization, and discrimination in classical conditioning? In operant conditioning, the concept of contingency is exemplified by an "if A, then B" relationship in which A and B, respectively, represent (AP99) (A) stimulus, response (B) Response, reinforcement (C) Stimulus, reinforcement (D) Response, stimulus (E) Stimulus, stimulus
80
Pavlov’s Experiments During conditioning, the neutral stimulus (tone) and the US (food) are paired, resulting in salivation (UR). After conditioning, the neutral stimulus (now Conditioned Stimulus, CS) elicits salivation (now Conditioned Response, CR) Unconditioned Stimulus (UCS): A stimulus that automatically and naturally triggers a response. Unconditioned Response (UCR): A unlearned, naturally occurring response to the unconditioned stimulus, like salivation in the dog when food is in the mouth. Conditioned Stimulus (CS): Originally a neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response. Conditioned Response (CR): A learned response to a previously neutral conditioned stimulus. 19 3. After several trials during which a dog is given a certain kind of food at the same time that a specific tone is sounded, there is evidence of conditioning if the dog salivates when (AP94) (A) The tone only is presented (B) The food only is presented (C) The food and tone are presented together (D) A different tone is presented with the food (E) A different kind of food is presented without a tone
81
Acquisition The CS needs to come half a second before the US for acquisition to occur. Because studies of learning show that events occurring close together in time are easier to associate than those occurring at widely different times, parents should probably avoid which of the following? (AP94) (A) Corporal punishment (B) Mild punishment (C) Consistent punishment (D) Inescapable punishment (E) Delay of punishment
82
Extinction When the US (food) does not follow the CS (tone), CR (salivation) begins to decrease and eventually causes extinction. Responses extinguish fastest when they are learned through which type of reinforcement schedule? (AP94) (A) Continuous (B) Negative (C) Variable-interval (D) Variable-ratio (E) Fixed-interval An individual's fear of dogs that is lost as the individual is exposed to dogs in nonthreatening situations is referred to by behaviorists as a fear that has been (AP99) (A) Satiated (B) Suppressed (C) Repressed (D) Extinguished (E) Punished A disappeared CS is called extinguished, not extinct.
83
Stimulus Generalization
Tendency to respond to stimuli similar to the CS is called generalization. Pavlov conditioned the dog’s salivation (CR) by using miniature vibrators (CS) on the thigh. When he subsequently stimulated other parts of the dog’s body, salivation dropped Can be adaptive, toddlers taught to fear cars…..and trucks and motorcycles etc. Or fear snake, fear all snakes 19 7.

Stimulus Discrimination
Discrimination is the learned ability to distinguish between a conditioned stimulus and other stimuli that do not signal an unconditioned stimulus. Can be used to discover what various organisms perceive (A) Prototype matching to organize information into categories (B) Maintaining information in memory through repetition (C) Differential treatment, usually negative, based on group membership (D) Recognizing an object as distinct from its surroundings (E) Learning to respond differently to similar stimuli Which is a definition of discrimination that most directly applies to classical conditioning?

Amnesias After losing his hippocampus in surgery, patient Henry M. (HM) remembered everything before the operation but could not make new memories. We call this anterograde amnesia. Damaged on purpose to control epilepsy, the surgery would never be done again, December 5, 2008 H. M., an Unforgettable Amnesiac, Dies at 82 By BENEDICT CAREY He knew his name. That much he could remember. He knew that his father’s family came from Thibodaux, La., and his mother was from Ireland, and he knew about the 1929 stock market crash and World War II and life in the 1940s. But he could remember almost nothing after that. In 1953, he underwent an experimental brain operation in Hartford to correct a seizure disorder, only to emerge from it fundamentally and irreparably changed. He developed a syndrome neurologists call profound amnesia. He had lost the ability to form new memories. For the next 55 years, each time he met a friend, each time he ate a meal, each time he walked in the woods, it was as if for the first time. John suffered a head injury in an accident five years ago. He now has clear memories of events that occurred before the accident, but he has great difficulty remembering any of the experiences he has had since the accident.

Language Influences Thinking
Linguistic Determinism (Whorf hypothesis): language determines the way we think. For example, he noted that the Hopi people do not have the past tense for verbs. Therefore, the Hopi cannot think readily about the past. Link Whorf (1956) Language and thinking intricately intertwine. Bilinguals may show different personalities when tested in different languages. Tribesmen in brazil have numbers for 1, 2 and more than that is many. They have difficulty with 1 to 1 correspondence. Put out 7 and ask them to put out the same number and they have difficulty (Gordon 2004) Naming arrows Bernstein…English speakers have more difficulty understanding place value eleven vs. Ship-il in Korean, which means ten-one English speakers have a harder time understanding math compared to many Asian languages. We say what is thirtyseven plus twenty-two, the Chinese say what is three ten seven and two tens two, the structure is implicit in the language…(Outliers, Malcom Gladwel) Average 4yo Chinese can count to 40, average 4yo American can count to 15, and can’t do 40 until they are 5 so they are already behind. …(Outliers, Malcom Gladwel) We say three/fifths many Asian languages say out of 5 parts take 3…(Outliers, Malcom Gladwel) According to Benjamin Whorfs linguistic relativity hypothesis, which of the following is true? (AP94) (A) lndividuals have a natural predisposition to learn language. (B) Individuals learn positive instances of concepts faster than they learn negative instances. (C) Children learn their first language from their relatives and their peer group. (D) Different languages predispose those individuals who speak them to think about the world in different ways.

Genetic Influences Studies of twins, family members, and adopted children together support the idea that there is a significant genetic contribution to intelligence. Intelligence scores of identical twins reared together match very well. (test reliability .9) so .85 is very high. Scores of fraternal twins are less similar 70% of intelligence score variation attributed to genetics (bochard 1996) Identical twins similar amounts of grey matter (Thompson 2001) Researchers have used genetics to make mice that learn more quickly. (Tsien 2000) The hypothesis that intelligence is in part inherited is best supported by the fact that the IQ correlation for (AP94) (A) Pairs of twins reared together is greater than the correlation for pairs of twins reared apart (B) Pairs of identical twins is greater than for pairs of fraternal twins (C) Pairs of fraternal twins is greater than the correlation for other pairs of siblings (D) Adopted children and their adoptive parents is greater than zero (E) Adopted children and their adoptive parents is greater than the correlation for the same children and their biological parents The correlations between the IQ scores of identical twins reared apart are lower than those of identical twins reared together.

Our physiology and cognitions create emotions. Emotions have two factors–physical arousal and cognitive label. Stanley Schachter and Jerome Singer proposed yet another theory which suggests Labeling arousal depends on attribution, the process of identifying the cause of an event. Gave epinephrine injections to people, some told side effects of injections others were not. Ones told their feeling was a side effect had not emotions. If told there was no side effects they “caught” the emotion of a researchers accomplice (Schacter & Singer 1962) This state experienced as two different emotions.

Expose patients to things they fear and avoid.
Exposure Therapy Expose patients to things they fear and avoid. Through repeated exposures, anxiety lessens because they habituate to the things feared.

Operant Conditioning Operant conditioning procedures enable therapists to use behavior modification, in which desired behaviors are rewarded and undesired behaviors are either unrewarded or punished. A number of withdrawn, uncommunicative 3-year-old autistic children have been successfully trained by giving and withdrawing reinforcements for desired and undesired behaviors.

Focuses in Social Psychology
Social psychology scientifically studies how we think about, influence, and relate to one another. Does his absenteeism signify illness, laziness, or a stressful work atmosphere? Was the horror of 9/11 the work of crazed evil people or ordinary people corrupted by life events? Social thinking involves thinking about others, especially when they engage in doing things that are unexpected. 43 2. Which type of psychologist would be interested primarily in studying whether people behave differently in groups than they do when alone? (AP04) (A) Experimental (B) Cognitive (C) Developmental (D) Social (E) Clinical “We cannot live for ourselves alone.” Herman Melville

Attributing Behavior to Persons or to Situations
Attribution Theory: Fritz Heider (1958) suggested that we have a tendency to give causal explanations for someone’s behavior, often by crediting either the situation or the person’s disposition. Preview Question 1: How do we tend to explain others’ behavior? How do we explain our own behavior? Sometimes attributions are valid According to attribution theory, Pablo is most likely to attribute his high score on a difficult exam to (AP94) (A) Good luck (B) His intelligence (C) His instructor's teaching ability (D) The low level of difficulty of the exam (E) His classmates' inadequate preparation for the exam Fritz Heider
168
Fundamental Attribution Error
Fundamental Attribution Error. The tendency to overestimate the impact of personal disposition and underestimate the impact of the situations in analyzing the behaviors of others. Woman acts aloof & critical or warm and friendly… some subjects told spontaneous, others told acting…. effect of telling subjects…nothing If she acted friendly they said she was friendly & vice versa. Attributed behavior to personal disposition even though it was situational. Especially in western individualistic cultures – disposition Asian cultures attribute more things to situations-possibly because they are more collective According to the theory of fundamental attribution error, when explaining the failures of others we usually underestimate the significance of (AP04) (A)Situational factors (B)Dispositional factors (C)Motivational factors (D)Support systems (E)Inherited traits We see Joe as quiet, shy, and introverted most of the time, but with friends he is very talkative, loud, and extroverted.
169
Actions Can Affect Attitudes
Why do actions affect attitudes? One explanation is that when our attitudes and actions are opposed, we experience tension. This is called cognitive dissonance. We rationalize “If I choose to do it I must believe it” Less coercion and more responsible we feel for a troubling act the more dissonance we feel. According to cognitive dissonance theory, human beings are motivated to (AP99) (A) Respond to an inborn need to pass their genes to the next generation (B) Maintain an optimal level of arousal (C) Satisfy basic needs such as hunger before proceeding to higher needs such as self actualization (D) Reduce tensions produced by inconsistent thoughts (E) Satisfy needs resulting from tissue deficits Which of the following do individuals experience when their behavior is inconsistent with their attitude? (AP04) (A)Approach-avoidance conflict (B)Cognitive dissonance (C)Intrinsic motivation (D)Homeostatic motivation (E)Overjustification To relieve ourselves of this tension we bring our attitudes closer to our actions (Festinger, 1957).

Social Influence Module 44
The failure of bystanders to give victims of automobile accidents needed assistance is sometimes explained as an instance of (AP94) (A) Group polarization (B) deindividuation (C) Situational attribution (D) Diffusion of responsibility (E) Mere exposure effect The more people present at a scene, the less likely it is that anyone will help a person in need. This phenomenon is a manifestation of (AP99) (A) Diffusion of responsibility (B) Social facilitation (C) Situational ambiguity (D) A social norm (E) Reciprocity Which of the following is considered an explanation of why bystander intervention is less likely to occur if there is a large number of witnesses to a crime? (AP04) (A)Prejudice (B)Social facilitation (C)Diffusion of responsibility (D)Group polarization (E)Self-efficacy

Group Pressure & Conformity
Suggestibility is a subtle type of conformity, adjusting our behavior or thinking toward some group standard. Solomon Asch 1955 5 ringers one subject 2 normal trials, trial 3 confederates say 3 matches the standard, subjects say 3 1/3rd of the time. Alone they err only about 1 in 100 times Which of the following was true of Solomon Asch’s experiments on conformity? (AP94) (A) People conformed if they knew and respected the authority figure present. (B) An increase from 7 to 12 confederates increased conformity by experimental subjects. (C) Experimental subjects conformed less frequently when their judgments were made known to the group. (D) About 99% of the judgments made by the experimental subjects were wrong. (E) If the confederates' judgments were not unanimous, the degree of conformity by experimental subjects decreased.

Group Pressure & Conformity
Informational Social Influence: An influence resulting from one’s willingness to accept others’ opinions about reality. A scene from one of Asch’s trials Solomon Asch’s findings on conformity might best be used to explain why (AP04) (A)Members of a family all like the taste of bananas (B)Adolescents follow fads in dress and hairstyle (C)People are less likely to accept blame for their failures than to accept credit for their successes (D)Bystander intervention is more likely to occur when few, rather than many, bystanders are present (E)Performance is enhanced in the presence of others William Vandivert/ Scientific American

Milgram’s Study: Results
Repeat experiment 65% followed instructions Highest obedience -Person giving orders nearby & perceived as legitimate authority figure More if authority associated with prestigious institution -Depersonalized or at a distance, (combat phenomenon, not fire at enemy) No role models for defiance Milgram on youtube Which of the following studies has had the most profound impact on ethical issues in psychological research? (AP94) (A) Stanley Milgram's study of obedience (B) Solomon Asch's study of conformity (C) Daryl Bem's study of self-perception (D) William McGuire's study of self-concept (E) Leon Festinger's study of cognitive dissonance Milgram on Youtube
174
Lessons from the Conformity and Obedience Studies
In both Asch's and Milgram's studies, participants were pressured to choose between following their standards and being responsive to others. In Milgram’s study, participants were torn between hearing the victims pleas and the experimenter’s orders. “Normal people can become agents of a terrible destructive process” Milgram We succumb gradually to evil (foot in the door phenomena) In Stanley Milgram's obedience experiments, subjects were LEAST likely to deliver maximum levels of shock when the (AP99) (A) Experiment was conducted at a prestigious institution (B) "Learner" screamed loudly in pain (C) Experimenter told hesitant subjects, "You have no choice, you must go on" (D) "Learner" said that he had a heart condition (E) Subjects observed other subjects who refused to obey the experimenter's orders

Individual Behavior in the Presence of Others
Social facilitation: Refers to improved performance on tasks in the presence of others. Triplett (1898) noticed cyclists’ race times were faster when they competed against others than when they just raced against the clock. Preview Question 4: How does the mere presence of others influence our actions? How does our behavior change with we act as part of a group? How do groups affect our behavior? Social psychologists study various groups: One person affecting another Families Teams Committees Drivers at lights take 15% less time to travel first 100 yards if another car is beside them (Towler) If observed we become aroused. This arousal strengthens the most likely response – the correct one on and easy task, an incorrect one on a difficult task. Expert pool players hit 71% of shots alone, 80% if people watch them… Poor shooters hit 36% alone, 25% when watched Social facilitation theory focuses on situations in which the presence of others causes an individual’s performance to (AP04) (A)Remain unchanged (B)Decline (C)Improve (D)Spontaneously recover (E)Become fixated Michelle Agnis/ NYT Pictures
176
Social Loafing The tendency of an individual in a group to exert less effort toward attaining a common goal than when tested individually (Latané, 1981). Why – People in groups feel less accountability Especially common among men in individualistic cultures. 43 or A club president discovers that contributions of club members drop when the total contribution of all members is published rather than the contributions of individuals. This drop can be explained by the phenomenon of (AP04) (A)Group polarization (B)Learned helplessness (C)Social loafing (D)Social facilitation (E)Socialization
177
Deindividuation The loss of self-awareness and self-restraint in group situations that foster arousal and anonymity. Tribal warriors who depersonalize themselves with face paint or masks more likely to kill, torture or mutilate captured enemies. (Watson 1973) Zimbardo 1970, hooded women delivered 2x more electric shock to a victim than identifiable women did. Second pic Which of the following concepts was advanced by social psychologists to help explain why people who are part of a crowd sometimes commit aggressive, antisocial acts that they would not commit if they were alone? (AP94) (A) Groupthink (B) Cognitive dissonance (C) Social facilitation (D) Deindividuation (E) Catharsis Which of the following explains the behavior of normally law-abiding people who act destructively when they are part of a crowd? (AP04) (A)Group polarization (B)The mere exposure effect (C)Deindividuation (D)Entrapment (E)Fundamental attribution error Mob behavior

Psychology of Attraction
4. Similarity: Similar views among individuals causes the bond of attraction to strengthen.
