What is Gain - loss effect?
Research on the gain-loss effect (Aronson & Linder, 1965) has found that we’re more attracted to people who initially dislike us but then change their minds after they get to know us than we are to people who express constant liking for us.
What is the immigrant paradox
Research has found that, for some immigrant groups, recent immigrants often have better health and educational outcomes than more established immigrants and nonimmigrants do. This is referred to as the immigrant paradox.
What is colourism?
it is a form of internalized racism and refers to discrimination within a racial group based on colour are other physical characteristics like hair texture or eye colour.
Stress-induced increases in cortisol levels in the hippocampus have been linked to impairments in the:
A. retrieval of procedural memories.
B. retrieval of declarative memories.
C. consolidation of procedural memories.
D. consolidation of declarative memories.
Research has found that increases in cortisol levels in the hippocampus as the result of stress enhances the encoding and consolidation of declarative memories when stress occurs prior to learning but impairs the retrieval of declarative memories when stress occurs prior to retrieval, with these effects being strongest for emotionally arousing material (Wolf, 2010).
When measuring the relationship between two variables, a restriction in range of scores on the variables will most likely produce a correlation coefficient that:
A. underestimates the actual relationship between the variables.
B. overestimates the actual relationship between the variables.
C. either under- or overestimates the actual relationship between the variables.
D. neither under- nor overestimates the actual relationship between the variables.
A. underestimates the actual relationship between the variables.
To determine the true relationship between variables, scores on both variables must be unrestricted in terms of range. When the range is restricted (e.g., when only low scorers are included in sample), the resulting correlation coefficient will underestimate their actual relationship.
What studies the variations in tone, rhythm, volume, and stress that are used to express emotions and modify or clarify the meaning of a verbal communication?
Paralanguage
Of the following, which is least likely to be the optimal intervention when a child’s target behavior is harmful to him/herself or others?
A. response cost
B. operant extinction
C. overcorrection
D. differential reinforcement
Operant extinction
Of the interventions listed in the answers, operant extinction would be the least desirable when the target behavior is harmful to the individual or others because extinction often causes an increase in the behavior (an extinction burst) before the behavior begins to decrease.
Reducing the amount of reinforcement for a behavior is referred to as _________
Thinning
Switching from a continuous to an intermittent schedule of reinforcement or from an FR-10 to an FR-20 schedule are examples of thinning. Thinning the reinforcement schedule once a behavior reaches its desired level helps increase resistance to extinction.
What it is called when two behaviors (Behaviors A and B) are being reinforced and the frequencies of Behavior A and Behavior B change when there is an alteration in the rate of reinforcement for one of the behaviors
Behavioural contrast
What is positive behavioral contrast?
when the amount of reinforcement for Behavior A is decreased while the amount of reinforcement for Behavior B is unaltered, Behavior A will decrease and Behavior B will increase. This is referred to as positive behavioral contrast.
What is negative behavioral contrast?
When the amount of reinforcement for Behavior A is increased while the amount of reinforcement for Behavior B is unaltered, Behavior A will increase and Behavior B will decrease. This is referred to as negative behavioral contrast.
Which intermittent reinforcement schedule produce the highest rate of responding and the greatest resistance to extinction
Variable Ratio schedule
Which law predicts that rate of responding will match the magnitude of the reinforcement.
Matching Law
According to which law, when two or more behaviors are concurrently reinforced on different schedules, the rate of performing each behavior is proportional to the frequency of reinforcement.
Matching Law
How it is called when a behavior increases because it was accidentally reinforced.
Superstitious behaviour
Why is Stimulus control is called two-factor learning?
Stimulus control is an example of two-factor learning, because combines operant and classical conditioning: Performance of a particular behavior is due to positive reinforcement (operant conditioning). Performance of the behavior in the presence of a positive discriminative stimulus but not in the presence of a negative discriminative stimulus is the result of discrimination training (classical conditioning).
What is stimulus control?
A behavior is brought under stimulus control when it occurs in the presence of one stimulus but not another stimulus. e.g., rats might learn that, when a light is blinking and they press a lever, a food pellet will be delivered; but, when the light is not blinking and they press the lever, a food pellet will not be delivered. In this situation, the blinking light is a positive discriminative stimulus (also referred to as just the discriminative stimulus or SD) because it signals that reinforcement will be delivered. In contrast, the non-blinking light is a negative discriminative stimulus (also referred to as the S-delta stimulus) because it signals that reinforcement will not be delivered
Gradually removing a prompt once the behavior is at the desired level is referred to as _________
Fading
Avoidance conditioning is the result of two-factor learning. It is combination which two factors?
It occurs when a stimulus signals that an unpleasant stimulus is about to be applied and a behavior occurs because it allows the individual to avoid the unpleasant stimulus. A dog might learn that a blinking light (associated with electric shock and is a conditioned stimulus - classical conditioning) signals that electric shock is about to be applied to the floor of its cage, and it jumps over the barrier (result of negative reinforcement - operant conditioning) as soon as the light starts to blink to avoid being shocked.
Under what conditions psychologists can use deception in research?
- it’s justified by the prospective value of the study,
- alternative procedures are unavailable, 3. participants are debriefed about the true nature of the study as early as is feasible (which may or may not be immediately after participation), and
- participants are allowed to withdraw their data from the study.
Org Psych
When conducting a(n) ___________, an organizational psychologist would assign points to a job’s compensable factors
Job Evaluation
The point system is a commonly used method of job evaluation. It involves determining the monetary value of a job by assigning points to the job’s compensable factors (e.g., effort, skill, responsibility, work conditions); summing the points to derive a total score; and using the total score to determine the appropriate compensation for the job.
Research
The central limit theorem predicts that, regardless of the shape of the population distribution of scores, a sampling distribution of means increasingly approaches the shape of:
A. the population distribution as the number of samples increases.
B. the population distribution as the sample size increases.
C. a normal distribution as the number of samples increases.
D. a normal distribution as the sample size increases.
D. a normal distribution as the sample size increases.
According to the encoding specificity hypothesis, forgetting is caused by inadequate:
A. retrieval cues.
B. elaborative rehearsal.
C. attention to details while encoding new information.
D. organization of new information.
Retrieval Cues
According to the encoding specificity hypothesis, retrieval from long-term memory is maximized when the conditions at the time of encoding new information are the same as the conditions at the time of information retrieval – e.g., when the person learns and retrieves information in the same environment or while in the same mood. When this occurs, conditions at the time of recall act as retrieval cues.
A supervisor tells you that the low job motivation of one of her newly hired supervisees is affecting his job performance, and she asks your advice about the best management style when working with him. As an advocate of ______________, you question the supervisor about some of the characteristics of the supervisee and his job tasks and, based on her answers, recommend that she adopt a supportive style with this supervisee.
A. Fiedler’s contingency theory
B. Dansereau, Graen, and Haga’s (1975) leader-member exchange theory
C. House’s path-goal theory
D. Vroom-Yetton-Jago’s leadership model
House’s Path Goal Theory
According to House’s (1971) path-goal theory, an effective leader adopts the style (directive, achievement-oriented, supportive, or participative) that best fits certain characteristics of the employee and the employee’s tasks.
Generalized onset seizures always:
A. include a loss of consciousness.
B. include motor symptoms.
C. include a loss of consciousness and motor symptoms.
D. begin with an aura.
A.include a loss of consciousness
There are two types of generalized onset seizures – generalized onset motor seizures (also known as tonic-clonic seizures) and generalized onset non-motor seizures (also known as absence seizures). Both include a loss of consciousness but, as their names suggest, only generalized onset motor seizures include motor symptoms. Although auras are most associated with focal onset seizures, there is evidence that they occur for some people with generalized onset seizures.
Beginning in early adolescence, the rate of major depressive disorder for females is about ________ times the rate for boys
1.5 to 3 times
Which of the following best describes implied consent?
A. It refers to a person’s informed consent when it is not written or documented.
B. It applies only when a person is believed to be a danger to self or others.
C. It is inferred from the behaviors or circumstances of a person.
D. It applies only when a person lacks the capacity to give informed consent.
It is inferred from the behaviours and circumstances of the person
Which of the following is true about the prescription and tapering of benzodiazepines for older adults?
A. Benzodiazepines that have a shorter half-life are preferred, and tapering should be slow.
B. Benzodiazepines that have a shorter half-life are preferred, and tapering should be rapid.
C. Benzodiazepines that have a longer half-life are preferred, and tapering should be slow.
D. Benzodiazepines that have a longer half-life are preferred, and tapering should be rapid.
A. Benzodiazepines that have a shorter half-life are preferred, and tapering should be slow.
Increasing age increases the half-life of the benzodiazepines, so, benzodiazepines with a shorter half-life are recommended for older adults. In addition, a slow taper of the drugs over several months is recommended to reduce the risk for and severity of withdrawal symptoms.
tapering schedule depending on the initial drug dose and duration of treatment
What is the range of scores for Reliability Coefficient?
0 to 1.0
closer the coefficient is to 1.0 the less the effect of measurement error and greater the consistency of scores
What is the range of scores for Criterion-related validity coefficient?
-1.0 to +1.0
The closer it is to 0 the lower the predicotr’s criterion-related validity
what would be the best for a company - a high or low selection ratio?
A low selection ratio is good for the company as it means it has more applicants to choose from.
What does it means when the base rate is low with regard to employee selection procedure?
It means that soemthing other than the slection procedure (e.g. inadequate training) is the problem becasue its not likely that use of current procedure resulats in shoosing least suitable applicants.
A moderate base rate (.50) is associated with greatest increase in decision-making accuracy
What for Brogden-Cronbach-Gleser Formula used?
It is used for utility analysis - method for evaluating the economic return on investment of human resource intervention such as staffing and training
What are Self-defining memory (SDM)?
Self-defining memory (SDM) is a component of episodic memory and consists of memories that contribute to the construction and maintenance of one’s personal identity.
What are characteristics of Self-defining memory?
According to Singer (2005), SDMs have five characteristics:
1. Emotional intensity,
2. Vividness,
3. High levels of repetition,
4. Linkage to similar memories, and
5. Connections to enduring concerns or unresolved conflicts.
Which aspect of an item characteristic curve (ICC) indicates the probability of choosing the correct answer to the item by guessing alone?
A. the position of the curve
B. the slope of the curve
C. the point at which the curve intercepts the x-axis
D. the point at which the curve intercepts the y-axis
D. the point at which the curve intercepts the y-axis
The various item response theory models produce item response curves that provide information on three parameters being
1. item difficulty,
2. item discrimination, and
3. the probability of guessing correctly.
`The probability of guessing correctly is indicated by the point at which the item response curve intercepts the y-axis.
