According to evolutionary psychology, which of the following does NOT account for individual differences?

What book marked the beginning of evolutionary thinking?

A gene that produces low levels of ________ activity in conjunction with ________ seems to increase the risk for developing antisocial behavior.

DRD4 is linked to attention deficit hyperactivity disorder.

When personality psychologists measure trait differences in extraversion, what kinds of direct observations are they making?

Which of the following attributes seems to have the lowest heritability coefficient?

Which factor below would be part of the so-called nonshared environment?

Men who score high on ________ are especially accurate when it comes to judging their mate value, whereas women who score high on ________ are especially accurate when it comes to judging their mate value.

The field of study that attempts to explain how individual differences in behavior (i.e., personality traits) are shared by biological relatives is called ________.

Kara is placing a personal ad in the local paper. According to evolutionary predictions about mate selection, she will most likely mention her ________ when describing herself.

There are controversies related to evolutionary theorizing with respect to the difficulty in providing an evolutionary explanation to rare behaviors. This has been called the ________.

A high heritability coefficient can result when the trait ________ across individuals or when genes are important in ________ sense.

What is the heritability coefficient? Explain how it is calculated and what information heritability statistics provide to researchers.

What term describes the willingness to engage in sexual activities in the absence of a committed relationship?

As a result of Timothy's genes, he went through puberty later than his peers. Because he was much smaller than other boys, they tended to pick on him, and he fought back to protect himself. As a young adult, Timothy is more aggressive than his peers. This scenario illustrates that his aggression is ________.

If the correlation between the shyness of a sample of dizygotic twin pairs is .25 and the correlation between the shyness of a sample of monozygotic twin pairs is .50, then the heritability coefficient for shyness is ________.
