| Term | Definition |
| General Intelligence (g) (Charles Spearman) | a general intelligence factor that according to Spearman and others underlies specific mental abilities and therefore measured by every task on an intelligence task. |
| Savant Syndrome | a condition in which a person otherwise limited in mental ability has an exceptional specific skill, such as in computation or drawing. |
| Multiple Intelligences (Howard Gardner) | supports the idea that intelligence comes in different packages. |
| Robert Sternberg | Triarchic Theory. Creative, Analytical, and Practical |
| Creative Intelligence | demonstrated in reacting adaptively to novel situations and generating novel ideas. |
| Analytical Intelligence | academic problem solving; assessed by intelligence tests, which present well-defined problems having a single right answer. |
| Practical Intelligence | often required for everyday tasks, which are frequently ill defined, with multiple solutions. |
| Emotional Intelligence | the ability to perceive, understand, manage, and use emotions. |
| Intelligence Test | a method for assessing an individuals mental aptitudes and comparing them with those of others using numerical scores. |
| Mental Age | a measure of intelligence tests performed devised by Binet; chronological age that most typically corresponds to a given level of performance. |
| Stanford-Binet | the widely used American revision (by Terman at Stanford University) of Binet’s original intelligence test. |
| IQ | defined originally as the ration of mental age (MA) to chronological age (CA) multiplied by 100 (thus, IQ=MA/CA x100). |
| Aptitude Test | a test designed to predict a person’s future performance; aptitude is the capacity to learn. |
| Achievement Test | a test designed to assess what a person has learned (OAT’s). |
| Weshler Adult Intelligence Scale (WAIS) | the most widely used intelligence test; contains verbal and performance (non-verbal) subtests. |
| Standardization | defining meaningful scores by comparison with the performance of a pre-tested standardization 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 half’s of the test, on alternative forms of the test, or on re-testing. |
| Validity | the extent to which test measures or predicts what its suppose to. |
| Content Validity | the extent to which a test samples the behavior that is of interest, such as driving test. |
| Predictive Validity | 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: (SAT’s). AKA criterion-related validity. |
| Stereotype Threat | a self-confirming concern that one will be evaluated based on a negative stereotype. |
| Alfred Binet | French psychologist and inventor of the first usable intelligence test, known at that time as Binet test basically today called IQ test. |
| Lewis Terman | was an American psychologist, noted as a pioneer in educational psychology in the early 20th century at Stanford University. |
