The proportion of variation among individuals that we can attribute to genes. The heritability of a trait may vary, depending on the range of populations and environments studied.
Heritability
Defining meaningful scores by comparison with the performance of a pretested group.
Standardization
A self-confirming concern that one will be evaluated based on a negative stereotype
Stereotype threat
A condition of limited mental ability indicated by an intelligence score of 70 or below and difficulty in adapting to the demands of life; varies from mild to profound
Intellectual disability
A symmetrical, bell shaped curve that describes the distribution of many types of data; most scores fall near the mean, or average and fewer and fewer near the extremes
Normal curve
A group of people from a given time period
Cohort
The success with which a test predicts the behavior it is designed to predict; it is assessed by computing the correlation between test scores and the criterion behavior
Predictive validity
A method for assessing an individual’ mental aptitudes and comparing them with those of others, using numerical scores
Intelligence test
The extent to which a test samples the behavior that is of interest
Content validity
A measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance.
Mental age
Defined originally as the ratio of mental age to chronological age multiplied by 100
Intelligence quotient
