You should present a cogent argument based on your critical analysis of the question posed, using appropriate psychological terminology.” Write your essays on separate sheets of paper.

Essay 1:

A. Numerous factors can help determine whether an adolescent wearing a costume and mask will damage property if he doesn’t get treats he asks for when trick-or-treating on Halloween. Define and discuss how each of the following concepts could affect the decision:

• superego

• level of moral development

• conformity

• deindividuation

• modeling

B. Discuss how each of the factors (in A) helps determine whether or not an adolescent wearing a Halloween costume and mask will damage property if he doesn’t get treats he asks for when “trick-or-treating” on Halloween.

Essay 2:

A neuroscientist thinks he has developed a drug that can stop the progression of Alzheimer’s disease in people who are in the initial stages of the disease. Design a research experiment that will support or refute his hypothesis. In your research design describe the following:

• sample

• assignment

• independent variable

• dependent variable

• experimental group

• control group

• possible confounding variable

• how you would determine whether or not the drug is effective

Section 1

1. A—(Chapter 8) Olfactory (smell) receptors in the nasal passages would detect the gas molecules and send impulses directly to the brain for fast perception and response.

2. A—(Chapter 13) Identical twins. Since they share the same genes, the differences between them would be a result of nurture. Identical quadruplets would be extremely rare, and so it would be difficult to find a large enough sample size for a study.

3. C—(Chapter 10) The children’s more aggressive behavior following the more violent cartoon supports Albert Bandura’s social learning theory of aggression studied in the Bobo doll study.

4. D—(Chapter 11) A morpheme is the smallest unit of language that carries meaning. Although a phoneme is the smallest unit of language, it may have no meaning.

5. E—(Chapter 17) Systematic desensitization is a behavior therapy especially effective in the treatment of phobias such as claustrophobia in this question. The patient learns through classical conditioning to replace the fear with relaxation.

6. A—(Chapter 12) Humanistic perspective pioneer Abraham Maslow places self-esteem and finally self-actualization as higher needs in his hierarchy of needs theory of motivation.

7. A—(Chapter 14) The Rorschach inkblot test is a projective test designed to reveal the unconscious mind and is a technique quite useful to the psychoanalytic therapist.

8. A—(Chapter 10) When the pigeon sees the yellow light instead of the green one, he generalizes his pecking response to a similar stimulus. The pigeon can be taught to discriminate between the two colored lights, but has not yet been trained to do so.

9. D—(Chapter 14) Carl Rogers is a humanistic psychologist who believes like Maslow that people are born good and that only the conditions of worth placed on the individual by society change this natural tendency.

10. A—(Chapter 7) Over half of the brain’s volume is composed of the cerebral cortex. The cerebral cortex is the section of the brain thought to be responsible for higher thought processing and covers all of the other structures of the brain.

11. A—(Chapter 16) Joey seems to have antisocial personality disorder. He shows no guilt when he hurts others. The condition is first evident in teen years, as in this case, and the criminal behavior often accelerates over time.

12. D—(Chapter 10) Modeling is a social cognitive process in which new behavior is learned by watching others and then imitating their actions.

13. D—(Chapter 14) Freud’s superego operates on the morality principle and, thus, overrides the impulse to cut class in this example and causes Andy to do the right thing by attending class.

14. A—(Chapter 18) Prejudice is the unjustifiable negative attitude toward a group and its members, while discrimination would be acting upon this attitude.

15. C—(Chapter 17) One technique used by Carl Rogers in his client-centered humanistic therapy is to give unconditional positive regard to his clients to undo the effects of conditions of worth and to allow the individual to realize his or her positive actualizing potential.

16. D—(Chapter 18) People dressed alike or disguised can easily lose their sense of identity and become less self-aware, which are characteristics of deindividuation.

17. D—(Chapter 13) Piaget’s formal operational thought is the final stage of reasoning, characterized by hypothetical thought, systematic planning, and abstract, logical reasoning abilities.

18. B—(Chapter 7) In patients with Parkinson’s disease, damage occurs in the dopamine-rich substantia nigra. With the degeneration of these neurons, movement problems begin to occur.

21. D—(Chapter 16) Brenda’s constant attention-seeking and egotistical attitudes are classic markers of the narcissistic personality.

22. C—(Chapter 5) Behaviorists discount the role of “mentalistic” aspects that cannot be directly observed.

23. A—(Chapter 13) Erikson’s sixth stage of psychosocial development occurs during young adulthood and is marked by the crisis of intimacy vs. isolation—a desire to form closer bonds to others. Many marriages are the result of this growing sense of intimacy, and difficulty in forming relationships may indicate tendencies toward isolation.

24. C—(Chapter 8) The height of the wave or its amplitude allows us to perceive loudness from sound waves.

25. B—(Chapter 11) Shannon’s inability to think of using her jeans and sweater as a pillow is an example of functional fixedness—not seeing unusual uses for familiar objects.

26. C—(Chapter 14) In his hierarchy of needs, Maslow theorizes that lower level needs must be met before higher level needs can be attained. Self-actualization is the uppermost need and cannot be attempted until esteem needs, the need level below it, are satisfied.

27. A—(Chapter 14) The MMPI-2 is the most widely used self-report inventory for personality assessment.

28. C—(Chapter 17) Behaviorists believe that we learn new behavior through rewards and punishment. Any maladaptive behavior can be changed by altering the consequences of that behavior.

38. A—(Chapter 11) According to the serial positioning effect, words at the beginning of the list are stored in your long-term memory. Words remembered at the end of the list are in your short-term memory, which lasts only 20 + seconds and would be forgotten 2 days later. Poorest recall would occur for words in the middle of the list.

39. A—(Chapter 14) Tony’s sense of self-efficacy or belief in his abilities to accomplish tasks should be maximized by all of these accomplishments.

40. B—(Chapter 12) Fixed-action patterns are species-specific innate behaviors unaffected by learning.

41. B—(Chapter 15) To standardize a test, each of the actions mentioned would be taken—pretesting of a sample population for whom the test is intended under uniform instructions.

42. B—(Chapter 16) Compulsive hand washing is a common experience of those suffering from obsessive-compulsive disorder. A compulsion is the repetition of some action over and over even though it serves no useful purpose.

44. C—(Chapter 8) Sensory adaptation is the lessening of perception of a stimulus with repeated stimulation, like the temperature of the pool water. You perceive the pool water as cold when you first jump in, but the neural firing decreases over time with repeated stimulation and you no longer notice it.

45. E—(Chapter 16) DSM-IV is a diagnostic guide used by mental health professionals to diagnose patients. It lists symptoms of these disorders, but does not list the causes of mental disorders.

46. C—(Chapter 12) According to set point theory, an individual’s regulated weight is balanced by adjusting food intake and metabolic rate.

47. C—(Chapter 7) Only the PET scan images function of the brain. The CAT and MRI both show the structures of the brain in good detail. The fMRI, like the PET, can show both structure and function.

48. A—(Chapter 16) To have been diagnosed with disorganized schizophrenia, Aaron would have had to have a break with reality and probably been unable to tell the difference between right and wrong. A person who is legally insane during the commission of acts constituting an offense is unable to appreciate the nature and quality, or the wrongfulness, of his acts. According to law, “Mental disease or defect does not otherwise constitute a defense.”

49. C—(Chapter 18) Group A is likely to become more entrenched. This is an example of group polarization.

50. C—(Chapter 11) Penfield’s studies suggest that the old memories are still present and probably have not been stimulated or needed to be retrieved recently.

51. B—(Chapter 14) Displacement, a Freudian defense mechanism, allows us to express feelings toward a group or individual perceived to be less threatening to us, rather than the direct target or ourselves.

52. D—(Chapter 13) Longitudinal studies follow the same group of people for a longer period of time. They are tested at several points, thus providing reliable data about age effects. Cross-sectional studies may be confounded by the cohort effect and are not as valid for measuring age effects.

53. B—(Chapter 12) Their goal seems more related to successful completion of the course with a passing grade than learning the material. Grades represent extrinsic rewards, while learning for pleasure and internal satisfaction represent intrinsic rewards.

54. B—(Chapter 10) Repeated presentations of the conditioned stimulus without the unconditioned stimulus brings about extinction in classical conditioning. The conditioned response will disappear.

55. B—(Chapter 6) The median is a measure of central tendency achieved by ordering the numbers consecutively and determining the middle number. Here there are nine numbers, so the 5th number, 8, is the median of the scores.

56. C—(Chapter 15) Because the AP exam in Psychology is supposed to measure what you have learned in a course already taken, it is an achievement test.

57. C—(Chapter 8) Transduction is the conversion of physical stimuli into changes in the activity of receptor cells of sensory organs. The rods and cones are stimulated by photons of light, while the hair cells in the cochlea are stimulated by sound waves.

58. C—(Chapter 9) When our interest decreases, we often daydream about seemingly irrelevant ideas.

59. E—(Chapter 11) The availability heuristic is a tendency to estimate the probability of certain events in terms of how readily they come to mind. Each time any of these events do occur, the media publicize the information very thoroughly.

61. C—(Chapter 12) A lesion in the ventromedial hypothalamus would cause a rat to continue to eat. It is theorized to be the “satiety” center, or off button, for hunger sensation, so if it were lesioned, the rat would continue to eat as long as the food supply was available.

62. C—(Chapter 12) Matina Horner’s studies concluded that bright women fear success because it is correlated with masculinity in our culture. Maria would attend a community college rather than a very competitive college. Those with fear of success tend to select easy or noncompetitive goals.

63. A—(Chapter 14) David McClelland and others used the TAT to assess achievement motivation in their subjects. The stories that subjects told interpreting the pictures displayed were rated for achievement themes.

64. D—(Chapter 6) In data sets that have a few outliers like the 42 and 38 here, the median is a better measure of central tendency than the arithmetic mean.

65. E—(Chapter 16) The medical model attributes mental illness to faulty processes in neurochemistry, brain structures, and genetics. Social circumstances would not be considered causative factors.

66. B—(Chapter 13) According to Kohlberg, most teens follow a conventional level of morality. Stage IV, or the law and order stage, says that you understand the need for laws and, thus, conform to them for the good of the community.

67. B—(Chapter 18) Irving Janis described the dangerous implications of groupthink during the disastrous Bay of Pigs invasion. The top executives may want to preserve group harmony, so they would tend to self-censor opposing viewpoints to those of the president. Bringing in outside consultants to play devil’s advocate will increase the likelihood that more possibilities will be explored and the pros and cons will be discussed before the decision is made.

68. C—(Chapter 6) Although Javier found someone who teaches the same subject at both time periods, confounding variables, such as the mean GPA of both groups, if left uncontrolled, are likely to give him faulty results.

74. A—(Chapter 6) The color of the paper is the independent variable. How long it takes students to answer questions is the dependent variable.

75. A—(Chapter 18) Hostile aggression is defined as inflicting pain upon an unwilling victim. The man is slapping his wife out of anger and consciously choosing to display it in this fashion.

76. E—(Chapter 10) Upon further investigation of Pavlov’s findings in classical conditioning, Rescorla and others found that conditioning occurs because of the expectation that follows the conditioned stimulus more so than just their pairing in time. This revised cognitive view is called the contingency model of conditioning.

78. C—(Chapter 16) Tommy’s blindness and deafness are the result of a conversion disorder. Excessive anxiety over witnessing the murder has caused these symptoms, which have no organic basis.

79. B—(Chapter 7) The peripheral nervous system is made up of all nervous tissue outside the central nervous system, which includes the brain and spinal cord. Each of the other answers includes aspects of the central nervous system.

80. E—(Chapter 7) The inability to understand language suggests damage to Wernicke’s area, located in the left temporal lobe. If the problem had been an inability to speak or find words, damage to Broca’s area in the left frontal lobe would have been the likely cause.

81. C—(Chapter 18) The Japanese culture is a collectivist society, which would blame the group or parents specifically for a child’s behavior. The other countries are individualistic societies, which would tend to blame the behavior on the individual, especially a 17-year-old capable of intelligent thought.

86. B—(Chapter 7) The pituitary gland secretes thyroid-stimulating hormone. The hypothalamus produces releasing factors.

87. E—(Chapter 15) All three of these findings are possible. Though the mean score may be higher for Asian Americans, the range of scores within a particular group (African Americans) is always much greater than is the mean score between two different groups (African Americans and Asian Americans). Neither of these tells us how any one individual will do.

Sample Essay

Sigmund Freud proposed a three-part theory of personality including the id, the ego, and the superego. The superego, or third part, develops last and operates on the morality principle. Most school-age children know the difference between right and wrong, and their conscience, what Freud called the superego, makes them feel guilty when they disobey authority figures. If the superego has overpowered the id, the adolescents will probably not destroy the property because of their guilt.

These adolescents are probably operating at the conventional level of morality according to Kohlberg’s moral development theory. His theory says that at different stages, individuals judge right and wrong based on their intellectual reasoning ability. In stage 3, they would base their decision on seeking approval from other members of the group, and in stage 4 they would base their decision on the laws of society. Young adolescents might very well reason that it is okay to damage the person’s property since they didn’t get the treats they asked for. Seeking approval of their peers, the majority rules. However, if the adolescents were in the law and order stage, they might decide that damaging others’ property was unlawful and, thus, would resist the temptation to break the law.

Conformity is very similar to the principle of Kohlberg’s stage 3 reasoning. It is adopting the attitudes and behaviors of groups that you belong to. Not wanting to be excluded from the group, members tend to go along. In this situation, one might jump to the conclusion that teens would be likely to damage property of those who did not give them treats. Conforming behavior operates on group norms, and whatever the majority decided to do in this situation, the others would be likely to follow.

Deindividuation is a state of high arousal in a large group situation. Antisocial acts are more likely to occur because of the anonymity of the individual group members. On this Halloween night, groups of adolescents who are already in costumes and masks, thus shielding their identity, would be more likely to damage property because of the emotional arousal felt in this situation. They are out seeking “treats” and, angered by someone’s refusal to comply with their request, they might turn to destructive measures. Individually, most of the adolescents would probably not do this, but collectively and because of the anonymity of the situation, they would be more likely to be carried away by the emotions of the situation.

Finally, modeling is defined as a learning method in which someone observes someone else doing a specific behavior and then imitates that behavior. Bandura says that others tend to model those they consider of equal or greater status. If there were one or more leaders in this group, whatever behavior they initiated would likely be imitated by others who were watching. With adolescents who may tend to take risks, Halloween night might be an opportunity to vandalize by those who had already “learned” this behavior and for others to imitate what they had seen, thus damaging the property of those who did not give them treats.

Scoring Rubric for Essay 2

This is a 10-point essay: 2 points assigned for the design of the experiment and 8 points for the individual components asked for in the question.

Design an experiment:

2 points for identification of two of the following: research question, hypothesis, ethics.

Question: Will a new drug stop the progression of Alzheimer’s disease in people who are in the initial stages of the disease?

Hypothesis: If the new drug is given to a sample of people in the early stages of Alzheimer’s, then it will stop the progression.

Ethics: Because this drug is experimental, patients who volunteer and show a baseline memory loss will be told that they may or may not be given the drug. Should it be found to be effective, with possible side effects noted, those receiving the placebo will be allowed to take the drug as well. The potential harm would be discussed with patients and informed consent must be given for participation. Patients may withdraw at any point during the experiment.

1 point for Sample—a subgroup of the population of Alzheimer’s patients that participates in the study; could be obtained by volunteers from a newspaper solicitation in major cities or from lists of patients with Alzheimer’s from gerontologists in the area. You want it to be representative of all early-stage patients.

1 point for Assignment—division of the sample into groups such that every individual has an equal chance of being put in either the drug or placebo group. Group matching would be important.

1 point for identifying the independent variable—drug/no drug or placebo.

1 point for identifying the dependent variable—effects of the drug on Alzheimer’s symptoms; degree of progression of symptoms.

1 point for identifying the experimental group—participants who receive the drug.

1 point for identifying the control group—participants who receive a placebo or no drug group.

1 point for mentioning possible confounding variables—sex of patients and varying ages; misdiagnosis; other medical conditions during the trial period; not taking the dosage as prescribed.

1 point for describing how you would determine effectiveness—comparison of two group baseline scores and final results after the experimental period. Inferential statistics such as t test or ANOVA to determine significance of results. A p value of .05 or less will be considered significant.

Sample Essay

For the purpose of this essay, my neuroscientist will be Dr. Hylton, and her new drug will be called Lacetyl. Her research question is whether her new drug is effective, and her hypothesis is that if she administers the drug for a period of 6 weeks or more, then patients with early symptoms of Alzheimer’s will not get worse. Collecting a representative sample is her first problem.

Since Alzheimer’s is usually definitively diagnosed with an autopsy to determine whether or not neural tangles and plaques are present, she must solicit elderly patients (age 75 or older) who are showing early symptoms and then carefully screen them to rule out other conditions. Tests might include not only blood and urine tests, but also cognitive functioning tasks, especially dealing with memory loss. She might solicit volunteers through newspaper ads, but because of the problem with diagnosis, she may wish to contact gerontologists or specialists dealing with patients with Alzheimer’s and solicit volunteers from them. Since impairment should be limited in the early stages, potential risks should be discussed with the volunteers, their written consent forms should be signed, and their identities should be kept anonymous. To prevent bias on her part, Dr. Hylton would create a double-blind condition in which neither she nor the patients will know whether or not they are taking the drug or the placebo. To prevent confounds, group matching will be used to assign the patients, with both groups representing a similar range of initial functioning.

The independent variable in this experiment is the drug and the dependent variable is its effectiveness in improving patients’ symptoms. The experimental group receives the drug and the control group the placebo. It might also be beneficial to have a second control group that receives no drug at all. The drug would be administered daily and weekly tests of urine, blood, and cognitive tasks would be repeated for a period of 6 weeks. Any potential negative side effects would be noted, and the experiment would be halted immediately if these proved dangerous to any subjects receiving the drug.

Potential confounds are many. If a prescription is given, the patients may forget to take the medication. Sex, age, race, and other demographic variables not controlled in the sample could also prove a problem. Other medical conditions during testing and improper diagnosis in the first place could throw off our results. Obviously, when this study is concluded, replication would be necessary.

To determine whether Lacetyl is effective or not, baseline results would be compared in subjects and the differences between the results in the placebo and drug groups compared. Using inferential statistics, we would try to determine whether or not there was a significant difference between the two groups by using t tests or ANOVA. If her p value is .05 or less, then she will conclude that the drug is effective and await further studies and replication.

Scoring and Interpreting Practice Exam 1

Now that you’ve finished Practice Exam 1 and scored your answers, you can examine your results. Did you get all of the questions correct for a particular chapter? That’s excellent. You don’t need to spend much time going over that topic. Did you answer several questions incorrectly for a particular chapter? Go over that material carefully.

You can roughly equate your results to an AP test score. To put an approximate AP score on the results of your practice test, follow these steps:
