Exam 3: Genes, Evolution, and Environment

Once a particular gene is located, it is relatively easy for researchers to identify its function.

Darwin suggested that language develops as the brain makes probability decisions that one word is likely to follow another.

Which of the following is true with regard to the heritability of intelligence?

In order to explain principles of the differences in intelligence between and within groups, the authors described a hypothetical tomato plant experiment. Based on this experiment it would be accurate to conclude that:

Distinguish between intersexual and intrasexual selection.

Evolution is:

There is no way to estimate the heritability of a trait or behaviour directly, and so scientists must infer it. Explain, in detail, two approaches that are used.

An example of a human tendency that is either present at birth, or develops rapidly during maturation, is a preference for familiar objects.

According to Chomsky, the surface structure of a sentence refers to:

It is clear that the kind of intelligence that produces high IQ scores is only weakly heritable.

The central distinction between human language and other communication systems is that language:

Match these achievements with the appropriate person. -He viewed heredity as the chief factor in determining human nature.

In regard to heredity and environment, it would be accurate to say that, overall, environment causes our IQ scores.

How might you determine whether flute-playing ability is a highly heritable trait? If you want to improve your flute playing and someone tells you that musical ability is heritable, should you stop practicing?

Professor Chung has designed a computer model to determine how children might be able to acquire linguistic features without an inborn language acquisition device. She is likely to view infants as:

________ emphasizes the evolutionary mechanisms that might help explain similarities in behaviour.

Which of the following is NOT one of the important facts about heritability?

Match these achievements with the appropriate person. -He proposed that humans possess an innate language acquisition device.

For many years, psychologists addressing questions about human differences tended to fall into two camps. Those who emphasized the role of genes in human diversity were called:

Match these descriptions with the appropriate concept. -A statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group.
