One Way to Understand How Early Environment Influences Behaviors in Similar

question 54

Multiple Choice

One way to understand how early environment influences behaviors in similar species is through the "cross-fostering" experimental technique. Suppose that the curly-whiskered mud rat differs from the bald mud rat in several ways, including being much more aggressive. Which of the following would be the best cross-fostering experiment to determine, if environment plays a role in the curly-whiskered mud rat's aggression?

• A) Cross curly-whiskered mud rats and bald mud rats and hand-rear the offspring to see if any grew up to be aggressive.
• B) Place newborn curly-whiskered mud rats with bald mud rat parents and place newborn bald mud rats with curly-whiskered mud rat parents. Finally, let some mud rats of both species be raised by their own species. Then you would compare the outcomes.
• C) Remove the offspring of curly-whiskered mud rats and bald mud rats from their parents, raise them in the same environment but without parents, and then compare the outcomes.
• D) Replace normal newborn mud rats with deformed newborn mud rats to see if it triggered an altruistic response.

Definitions:

Reliability

The degree to which test scores are free from errors of measurement, also, the capacity of an instrument to provide consistent results. See “test-re-test,” “alternative forms,” and “internal consistency”.

Validity

The degree to which all of the accumulated evidence supports the intended interpretation of test scores for the intended purpose. Validity is a unitary concept that attempts to answer the question: How well does a test measure what it’s supposed to measure?

Guilford's Cognitive

Refers to a model developed by psychologist Joy Paul Guilford that categorizes human intelligence into operations, contents, and products.

Functions

In mathematics, functions are defined as relationships between a set of inputs and a set of permissible outputs, where each input is related to exactly one output.
