variable and dependent variable? - ANS - IV: Film violence (present vs absence)

diet, while the other group continues to receive its regular diet. In this experiment, what
is the term used to describe the maze-running performance of the rats - ANS - Dependent
variable

response to group pressure. What is the independent variable and dependent variable? -

,Affective forecasting - ANS - Efforts to predict one's emotional reaction to future events

reasoning skills
All 200 of these applicants are hired and put to work selling computers, After six months,
Professor Sam correlates the new workers' aptitude test scores with the dollar value of
the computers that each sold during the first six months on the job. This correlation
turns out to by -0.21. This finding suggests the test may lack_________ - ANS -
Criterion-related validity
An organizational psychologist develops a new training program to improve clerks'
courtesy toward customers in a large chain of retail stores. She conducts an experiment
to see whether the training program leads to a reduction in the number of customer
complaints. What is the independent variable and dependent variable? - ANS - IV:
Courtesy training (Training vs no training)
DV: Number of customer complaints
Anecdotal evidence - ANS - Consists of personal stories about specific incidents and
experiences
Aptitude test - ANS - Asses specific types of mental abilities
Argument - ANS - Consists of one or more premises that are used to provide support for
a conclusion
Arthur Jensen - ANS - Intelligence is largely genetic in origin and therefore genetic
factors are strongly implicated as the cause of ethnic differences in intelligence
Assumptions - ANS - Premises for which no proof or evidence is offered
At the request of the HiTechnol and computer store chain, Professor Sam develops a test
to measure aptitude for selling computers. Two hundred applicants for sales hobs at
HiTechnol and stores are asked to take the test on two occasions, a few weeks apart. A
correlation of +0.82 is found between applicants's scores on the two administrations of
the test. Thus, the test appears to possess reasonable_________ - ANS - Test-retest
reliability
At which step of the research process did researchers create operational definitions for
their variables? - ANS - Step 1: Formulate a testable hypothesis
, Back at the university, Professor Sam is teaching a course in theories of personality. He

Content Validity
Behavioural Component of Emotions - ANS - People can accurately and quickly discern
emotions from facial expressions
Between subjects design - ANS - Each participant is in only one condition
Binet and Simon - ANS - Focused on assessing children and identifying mentally
subnormal ones
Used abstract reasoning skills
Used mental age to say if a child was average, advanced or retarded
Biological correlates of intelligence - ANS - Research indicates that both white and grey
matter in the brain are important in determining intelligence. New research also indicates
that gyrification is positively correlated with intelligence
Bisexual - ANS - Likes members of either sex
Body Mass Index BMI - ANS - An individual's weight (in kilograms) divided by height (in
meters) sqared
Brain and behavioural component - ANS - Neural correlates of emotions measure brain
activity. They found a baseline array of brain areas active in neutral face processing
(fusiform gyrus) but additional areas active in response to non-neutral emotions
Can sight and smell of food affect appetite - ANS - When you see or smell food your
insulin levels can rise
Cannon-Bard - ANS - Stimulus>Subcortical brain activity > conscious feeling+Autonomic
arousal (simultaneously)

Case study - ANS - An in depth investigation of an individual subject
CCK - ANS - is secreted by the intestine and acts on the hypothalamus to decrease
hunger/food intake
Choice - ANS - Is often kept in check by their associated costs which are also what
