Exam 3: Genes, Evolution, and Environment

Because of the way our species evolved, many tendencies are either present at birth in all humans or develop rapidly during maturation. An example of one of these tendencies would be/an:

Sociobiologists predict that, compared to males, females are more likely to:

Infants as young as six weeks can derive simple linguistic rules from a string of sounds.

Which of the following is NOT true with regard to biological and genetic factors and intelligence?

Children in different cultures go through different stages of language development.

Poor prenatal care is one of the environmental factors that hinders intelligence.

Many psycholinguists believe that an innate capacity for language evolved in humans because it enhanced chances for survival.

The average IQ score for each age group is arbitrarily set at 100.

Researchers in ________ emphasize the evolutionary mechanisms that might help explain commonalities in areas of human psychology.

With the left hand, a person grabs a handful of tomato seeds that vary genetically from a bag and plants the seeds in a pot. With the right hand, this person grabs seeds from the same bag and plants them in a second pot. The first pot has enriched soil and exposure to sunlight, whereas the nutrients in the second pot's soil have been depleted and the pot is placed in a dark corner. When the tomato plants grow:

For adults, heritability estimates average around 0.30 to 0.35; that is, about one-third of the variance in IQ scores is explainable by genetic differences.

What two processes during the formation of sperm and eggs help explain genetic changes within a population?

Edward L. Thorndike, one of the leading psychologists of the early 1900s, claimed that in the actual race of life the chief determining factor is:

The A, T, C, and G molecules in DNA code for the synthesis of:

An example of a human tendency that is either present at birth, or develops rapidly during maturation, is an attraction to novelty.

According to the principle of natural selection, genetic variations become more common over time if they are adaptive in a particular environment.

Based on heritability estimates, it is likely that as we age, genetics will account for ________ of the observed individual differences in IQ.

Those who believe that language and grammar are innate deny that nurture plays any significant role in language development.

The dog chased the Frisbee. The Frisbee was chased by the dog. These sentences have the same:

Which of the following traits would be LEAST likely to be "selected" by natural selection?
