Behavior genetics

Question 1

Modern behavior genetics incorporates the accepted view that complex traits are determined by

Answer 1

heredity and environment in interaction

Question 2

Behavior genetics also takes on the role of genetic predispositions or vulnerabilities. Genetic predispositions are

Answer 2

Inherited and are expressed in behavior to varying degrees, or not at all, depending upon environmental influences

Question 3

A person might inherit a predisposition toward severe depression, but whether that person actually becomes severely depressed can depend upon a host of overlapping influences, ranging from family situation to economic support, to particular traumatic experiences, and so forth. This is an example of

Answer 3

Genetic predisposition

Question 4

Thus, even if (or when) researchers know how all of the genetic information encoded in our DNA expresses itself, behavior genetics will still be important because it recognizes the epigenetic processes and

Answer 4

interactive nature of heredity and environment

Question 5

The primary tool of behavior genetics is the statistical technique of correlation, which measures

Answer 5

concordance

Question 6

The proportion of a trait, such as intelligence, that is thought to result from inherited, genetic factors.

Answer 6

heritability

Question 7

In this experiment, three randomly assigned groups of preschool boys and girls watched a film in which an adult model “beat up” an inflated, adult-sized Bobo doll in specific ways. One group saw the adult model rewarded with praise from another adult at the end of the film. A second group saw the model punished by being scolded, and a third group saw the model experience no consequences. What was the result of the Bobo doll experiment?

Answer 7

Although the boys behaved more aggressively than the girls in all three independent variable groups, less aggression was expressed by both boys and girls in the group that saw the adult model punished than in the other two groups

Question 8

What was the independent variable of the Bobo doll experiment?

Answer 8

The consequences of aggression for the adult model depicted in the film

Question 9

What was the dependent variable of the Bobo doll experiment?

Answer 9

Researchers counted the number of aggressive acts the children displayed in their play;
