Document Summary
Behavioral genetics- a research specialty that evaluates both genetic and environmental influences on the development of behavior. Chronological age- what we commonly refer to as age; years in life. Concordance rate (similarity index)- an index of similarity between individuals. The simplest form of concordance rate is the percentage of instances in which 2 individuals exhibit similar behaviors or characteristics. Concurrent validity- to the extent to which test scores correlate with scores on other relevant measures administered at the same time. Construct validity-the extent to which test scores correlate with other measures of behaviors in a logical and theoretically consistent way. Requires a demonstration of all aspects of validity. Content validity- the degree to which test items adequately measure all aspects of the construct in interest. Crystalized ability- one of two higher-order factors of intelligence conceived by. Refers to the intellectual capacities obtained through culture-based learning.
