Individual Differences Scaling
- Quantifies and compares individuals on a specific trait using statistical methods.
- Commonly applied with standardized assessments (e.g., personality and intelligence tests).
- Helps relate individual variation to personality, cognition, and behavior and can inform interventions.
Definition
Section titled “Definition”Individual differences scaling is a statistical method used to measure and compare the differences between individuals on a particular trait or characteristic.
Explanation
Section titled “Explanation”This method is used in psychology and other social sciences to characterize how people differ on attributes such as personality, cognition, and behavior. It relies on standardized tests and statistical techniques to place individuals on continua or to assign scores for specific abilities, enabling comparison across people and examination of how those differences relate to other factors. Results from individual differences scaling can be used to inform research and to develop interventions or strategies that address observed variation in applied settings.
Examples
Section titled “Examples”Myers-Briggs Type Indicator (MBTI)
Section titled “Myers-Briggs Type Indicator (MBTI)”The MBTI is a widely-used personality test that assesses four dimensions of personality: extraversion vs. introversion, sensing vs. intuition, thinking vs. feeling, and judging vs. perceiving. By answering a series of questions, individuals can be placed on a spectrum for each of these dimensions, which can then be used to identify their overall personality type.
Wechsler Adult Intelligence Scale (WAIS)
Section titled “Wechsler Adult Intelligence Scale (WAIS)”The WAIS is a commonly-used intelligence test that assesses a variety of cognitive abilities, including verbal comprehension, perceptual organization, working memory, and processing speed. By completing a series of tasks and questions, individuals can be given a score for each of these abilities, which can then be used to determine their overall level of intelligence.
