Individual Differences Flashcards
Intelligence test
A method for assessing an individual’s mental aptitudes and comparing them with those of others, using numerical scores
General intelligence
A general intelligence factor that, according to spearman and others, underlies specific mental abilities and is therefore measured by every task on an intelligence test
Factor analysis
A statistical procedure that identifies clusters of related items on a test; used to identify different dimensions of performance that underlie a person’s total score
Savant syndrome
A condition in which a person otherwise limited in mental ability has an exceptional specific skill, such as drawing
Grit
Passion and perseverance in the pursuit of long term goals
Intelligence
Mental quality consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations
Emotional intelligence
The ability to perceive, understand, manage, and use emotions
Mental age
A measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance. A child who does as well as the average 8 year old has the mental age of an 8 year old
Stanford-Binet
The widely used American revision (by Terman) of Binet’s original intelligence test
Intelligence quotient
Defined originally as the ratio of mental age to chronological age multiplied by 100
Achievement test
A test designed to assess what a person had learned
Aptitude test
A test designed to predict a person’s future performance; aptitude is the capacity to learn
Wechsler Adult Intelligence Scale
Most widely used intelligence test; contains verbal and performance subtests
Standardization
Defining uniform testing procedures and meaningful scores by comparison with the performance of a pre tested group
Normal curve
The symmetrical, bell-shaped curve that describes the distribution of many physical and psychological attributes.
Reliability
The extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting
Validity
The extent to which a test measures or predicts what it is supposed to
Content validity
The extent to which a test samples the behavior that is of interest
Predictive validity
The success with which a test predicts the behavior it is designed to predict; computes correlation
