tough Qs with answers Flashcards
According leader-member exchange theory, what are qualities which a leader dtermines as important in thier subordinates?
Dansereau, Graen, and Haga’s (1975) leader-member exchange theory is based on the assumption that leader effectiveness and subordinate outcomes are determined by the nature of the interactions between the leader and the subordinate. It proposes that subordinates are treated as in-group or out-group members based on whether or not the leader perceives them as being competent, trustworthy, and willing to assume responsibility.
In the context of test construction, “shrinkage” is associated with:
A. inter-rater reliability.
B. factor analysis.
C. incremental validity.
D. cross-validation.
Shrinkage is associated with cross-validation and refers to the fact that a validity coefficient is likely to be smaller than the original coefficient when the predictor(s) and criterion are administered to another (cross-validation) sample. Shrinkage occurs because the chance factors that contributed to the relationship between the predictor(s) and criterion in the original sample are not present in the cross-validation sample.
Alma A., a 68-year-old retired real estate agent, is brought to therapy by her daughter who says that Alma has become forgetful, has difficulty concentrating, and seems depressed. The presence of which of the following would suggest that Alma’s symptoms are more likely due to a neurocognitive disorder than to pseudodementia (major depressive disorder)?
A. Alma’s daughter says her mother’s symptoms began soon after the family dog died.
B. Alma’s daughter says her mother’s symptoms are worse in the evening.
C. Alma often answers “I don’t know” in response to assessment questions.
D. Alma exaggerates her cognitive problems.
Major depressive disorder and neurocognitive disorder share some symptoms, but they also differ in important ways. The behaviors described in answers A, C, and D are more characteristic of pseudodementia than of a neurocognitive disorder. In contrast, worsening of symptoms in the evening (“sundowning”) is more characteristic of a neurocognitive disorder.
The assessment of treatment fidelity focuses on which of the following?
A. efficacy and effectiveness
B. reliability and validity
C. differentiation, adherence, and competency
D. familiarity, confidence, and preparedness
Treatment fidelity refers to the degree to which a treatment is delivered as intended and is affected by the degree to which the therapist delivered only the target treatment and no other treatments (differentiation), the therapist’s adherence to the treatment protocol (adherence), and the therapist’s competence in delivering the treatment (competency). Consequently, these three factors are the primary targets of an evaluation of a treatment’s fidelity.
When designing a training program, providing “identical elements” is most important for:
A. maximizing trainee motivation.
B. ensuring transfer of training.
C. setting realistic training goals.
D. retraining older workers.
According to the principle of identical elements, the more similar the training and performance situations are, the greater the transfer of training.
An organizational psychologist would most likely be hired by a company to conduct a job evaluation for the purpose of:
A. establishing comparable worth.
B. determining the training needs of newly hired employees.
C. developing performance appraisal measures.
D. writing detailed job descriptions.
A job evaluation is conducted to facilitate decisions related to compensation. It’s often used to establish comparable worth, which is the principle that workers who perform jobs that require the same skills and responsibilities or that are of comparable value to the employer should be paid the same.
For a practitioner of Beck’s cognitive behavior therapy, the automatic thoughts associated with depression reflect which of the following?
A. a lack of control over one’s emotions, behavior, and environment
B. should’s and must’s
C. negative views of oneself, the world, and the future
D. catastrophic interpretations of both negative and neutral events
Beck’s (1979) cognitive model of depression describes it as involving a negative cognitive triad that consists of negative views of oneself, the world, and the future.
John Jr. just turned 14 and has started demanding to be allowed to make his own decisions and to have more privileges and independence from the family. In response, John’s parents continue to treat him like a child and have become more punitive in an attempt to keep things the way they were. The parents’ response to John’s demands illustrates which of the following?
A. positive feedback
B. negative feedback
C. reframing
D. restraining
Negative feedback serves to maintain the status quo (i.e., to keep things the way they were), while positive feedback promotes change. Reframing and restraining are paradoxical techniques used by therapists to alter behavior.
Dr. Miller is hired by an insurance company to develop a performance appraisal measure for salespeople. She’s most likely to recommend that the company use a relative measure (as opposed to a Likert-type rating scale) because relative measures:
A. are more acceptable to both raters and rates.
B. allow the rater to focus on typical (rather than maximum) performance.
C. are less susceptible to some rater biases.
D. provide more useful information for employee feedback.
An advantage of relative job performance measures is that they reduce leniency, strictness, and central tendency rater biases.
A problem with using percent agreement as a measure of inter-rater reliability is that it may:
A. underestimate reliability because it’s susceptible to rater biases.
B. overestimate reliability because it’s susceptible to rater biases.
C. underestimate reliability because it’s affected by chance agreement.
D. overestimate reliability because it’s affected by chance agreement.
A certain amount of chance agreement between two or more raters is possible, especially for behavior observation scales when the behavior occurs frequently. Percent agreement is easy to calculate but, because it’s affected by chance agreement, it may overestimate a measure’s inter-rater reliability.
When lithium has not reduced the symptoms of mania for an individual who has received a diagnosis of bipolar disorder, an alternative is:
A. disulfiram.
B. carbamazepine.
C. propranolol.
D. guanfacine.
Anticonvulsant drugs are often prescribed for individuals with bipolar disorder who have not responded to lithium or cannot tolerate its side effects. Carbamazepine is one of the anticonvulsant drugs that has been found useful for treating mania.
Wolpe (1958) believed that counterconditioning was responsible for the effectiveness of his technique of systematic desensitization for eliminating an anxiety response to a particular stimulus. However, studies using the dismantling strategy found that its effects are actually due to:
A. extinction.
B. higher-order conditioning.
C. satiation.
D. stimulus discrimination.
Use of the dismantling strategy to identify the effects of the elements of an intervention involves comparing the elements by administering different elements to different groups of subjects. When this strategy was used to determine which elements of systematic desensitization accounted for its effectiveness, researchers found it was repeated exposure to the feared (conditioned) stimulus that eliminated the anxiety response and that pairing the feared stimulus with a stimulus that produced relaxation (counterconditioning) was unnecessary. In other words, the anxiety response was extinguished by repeatedly exposing the individual to the feared stimulus.
As a favor to another psychology professor, Dr. Anand requires students in his Psychology 101 class to participate in the professor’s research project. In terms of the requirements of the APA Ethics Code and the Canadian Code of Ethics, Dr. Anand’s requirement is:
A. acceptable as long as Dr. Anand believes that participation in the study will benefit his students.
B. acceptable as long as students are told about this requirement during the first class meeting.
C. acceptable only if students are given the choice of participating in the study or completing an alternative assignment.
D. acceptable only if Dr. Anand is not involved in the research project.
This situation is addressed in Standard 8.04(b) of the APA Ethics Code and Standard I.36 of the Canadian Code of Ethics. Standard 8.04(b) states that “when research participation is a course requirement or an opportunity for extra credit, the prospective participant is given the choice of equitable alternative activities.”
The Oregon model of parent management training developed by Gerald Patterson and his colleagues (1982) was based on their research that found a link between high levels of aggressiveness in children and:
A. early attachment insecurity.
B. rejecting/neglecting parents.
C. coercive family interactions.
D. a disorganized home environment.
Patterson et al. found that aggression and other antisocial behaviors in children were related to coercive family interactions that become progressively more coercive over time, with parents using increasingly harsh punishments and children becoming more disruptive and aggressive.
When an examinee’s scores on the L, F, and K scales of the MMPI-2 assume a V-shape with a low score on the F scale and high scores on the L and K scales, this suggests which of the following?
A. The examinee attempted to make a favorable impression.
B. The examinee attempted to fake a mental illness.
C. The examinee answered half of the items “true” and the other half “false.”
D. The examinee answered all of the items “true.”
The L, F, and K scales are three of the MMPI-2’s validity scales and the L-F-K profile indicates an attempt to “fake good” when it is V-shaped (low F scale score and high L and K scale scores) and an attempt to “fake bad” when it has an inverted-V shape (high F scale score and low L and K scale scores).
Neurocognitive disorder due to Alzheimer’s disease and neurocognitive disorder with Lewy bodies (NCDLB) can be difficult to distinguish, especially in their early stages, but there are differences. Which of the following does NOT accurately describe a difference between the two disorders?
A. Motor disturbances are more prominent in early Alzheimer’s disease than in early NCDLB.
B. Memory loss is usually a more prominent early symptom of early Alzheimer’s disease than of early NCDLB.
C. Nonvisual hallucinations and systematized delusions are more common in early NCDLB than in early Alzheimer’s disease.
D. Orthostatic hypotension and other autonomic disturbances are more common in early NCDLB than in early Alzheimer’s disease.
Key differences between Alzheimer’s and dementia with Lewy bodies
1. Memory loss tends to be a more prominent symptom in early Alzheimer’s than in early DLB. However, advanced DLB may cause memory problems in addition to its more typical effects on judgment, planning and visual perception.
2. Movement symptoms are more likely to be an important cause of disability early in DLB than in Alzheimer’s. However, Alzheimer’s can cause problems with walking, balance and getting around as it progresses to moderate and severe stages.
3. Hallucinations and misidentification of familiar people are significantly more frequent in early-stage DLB than in Alzheimer’s.
REM sleep disorder is more common in early DLB than in Alzheimer’s.
4. Disruption of the autonomic nervous system — such as causing a blood pressure drop on standing, dizziness, falls and urinary incontinence — is much more common in early DLB than in Alzheimer’s.
Moffitt’s (1993) “maturity gap” is most useful for understanding the etiology of which of the following disorders?
A. oppositional defiant disorder
B. late-onset attention-deficit/hyperactivity disorder
C. intermittent explosive disorder
D. adolescent-onset conduct disorder
T. Moffitt distinguished between two types of antisocial behavior in youth: Her life-course persistent type ASPD corresponds to the childhood-onset type of conduct disorder, while her adolescence-limited type corresponds to the adolescent-onset type ASPD. According to Moffitt, the life-course persistent type is the more serious disorder and is due to inherited or acquired neurobiological and neuropsychological factors, while the adolescence-limited type is due to a “maturity gap,” which is the gap between an adolescent’s biological and social maturity (Adolescence-limited and life-course persistent antisocial behavior: A taxonomy, Psychological Review, 100, 674-701, 1993).
The Kuder-Richardson Formula 20 (KR-20) can be used to estimate a test’s ____________ reliability when test items are scored dichotomously.
A. alternate forms
B. internal consistency
C. test-retest
D. inter-rater
KR-20 is a variation of coefficient alpha that can be used to evaluate a test’s internal consistency reliability when test items are scored dichotomously (e.g., as correct or incorrect).
A problem with split-half reliability is that it essentially involves calculating a reliability coefficient for two forms of the test that are half as long as the original test, and shorter tests tend to be less reliable than longer ones. How can this be corrected?
A split-half reliability coefficient underestimates a test’s reliability and is usually corrected with the Spearman-Brown prophecy formula, which is used to determine the effects of lengthening or shortening a test on its reliability coefficient.
A young man taking a conventional antipsychotic as a treatment for schizophrenia develops tardive dyskinesia. Of the following, which would be the best course of action in this situation?
A. increase the dose of the conventional antipsychotic
B. replace the conventional antipsychotic with an atypical antipsychotic
C. immediately discontinue the conventional antipsychotic
D. have the patient take a low dose of a dopamine antagonist
The atypical antipsychotics are less likely to cause tardive dyskinesia and, if a patient’s symptoms require continued treatment with an antipsychotic drug, switching to an atypical drug is an option. The actions described in the other answers would increase the symptoms of tardive dyskinesia. (Withdrawing the conventional antipsychotic is also an option but gradual withdrawal is preferred because symptoms may worsen if the drug is abruptly withdrawn.)
