Professionals in this field use various tests and assessment tools to evaluate individuals' cognitive strengths and weaknesses, providing valuable insights for educational, clinical, and vocational settings. This glossary covers essential terms, concepts, and acronyms related to the assessment of intelligence and cognitive functioning, organized alphabetically for easy navigation.
Assessment Battery #
A collection of tests and measures used together to evaluate an individual's cognitive abilities and other psychological constructs. An assessment battery typically includes measures of intelligence, cognitive functioning, academic achievement, and sometimes personality or emotional functioning.
Cattell #
Horn-Carroll (CHC) Theory: A widely accepted framework for understanding cognitive abilities, the CHC theory proposes that intelligence consists of broad abilities (e.g., fluid reasoning, crystallized intelligence, processing speed, and memory) and narrow abilities (e.g., deductive reasoning, inductive reasoning, and short-term memory).
Cognitive Abilities #
The mental processes and skills involved in perception, learning, memory, language, problem-solving, and decision-making. Cognitive abilities are often classified into various domains, such as verbal, mathematical, spatial, and perceptual abilities.
Cognitive Assessment #
The process of evaluating an individual's cognitive abilities using various tests and measures, typically aimed at identifying strengths and weaknesses in thinking, learning, and problem-solving.
Cognitive Constructs #
Theoretical concepts used to describe and explain cognitive abilities, such as intelligence, memory, attention, or executive functioning. Cognitive constructs are often measured using psychological tests and assessments.
Cognitive Processes #
The underlying mental activities involved in cognitive functioning, including attention, perception, memory, learning, language, problem-solving, and decision-making.
Crystallized Intelligence #
A type of intelligence that reflects an individual's accumulated knowledge, skills, and experiences, typically measured through tests of verbal and general information.
Differential Diagnosis #
The process of distinguishing between two or more related disorders based on an individual's symptoms, test results, and other relevant information. In cognitive assessments, differential diagnosis may help identify specific learning disabilities, intellectual disabilities, or other neurodevelopmental disorders.
Executive Functions #
A set of higher-order cognitive processes involved in planning, organizing, initiating, monitoring, and adjusting behavior. Executive functions include skills such as problem-solving, decision-making, cognitive flexibility, inhibition, and working memory.
Fluid Intelligence #
A type of intelligence that represents an individual's ability to reason, problem-solve, and think abstractly, typically measured using tests of nonverbal or figural reasoning.
Intelligence #
A broad cognitive ability that involves various mental processes, such as problem-solving, reasoning, planning, abstract thinking, learning, and understanding complex ideas. Intelligence is often measured using intelligence tests, such as the Wechsler Adult Intelligence Scale (WAIS) or the Stanford-Binet Intelligence Scales.
Intellectual Disability #
A neurodevelopmental disorder characterized by significant limitations in intellectual functioning and adaptive behavior, with onset before the age of 18. Intellectual disability is typically diagnosed using a comprehensive cognitive assessment and adaptive behavior evaluation.
Learning Disability #
A neurodevelopmental disorder characterized by significant difficulties in one or more academic areas (e.g., reading, mathematics, or written expression) despite adequate intelligence and educational opportunities. Learning disabilities are typically diagnosed using a comprehensive cognitive assessment, academic achievement testing, and other relevant measures.
Mental Age #
A concept used in intelligence testing to describe an individual's level of cognitive development relative to their chronological age. Mental age is often used to calculate an individual's intelligence quotient (IQ).
Neuropsychological Assessment #
A comprehensive evaluation of an individual's cognitive, emotional, and behavioral functioning, typically conducted to help diagnose and understand neurodevelopmental, neurological, or psychiatric conditions. Neuropsychological assessments often include measures of intelligence, memory, attention, executive functioning, and other cognitive abilities.
Processing Speed #
A cognitive ability that represents an individual's speed and efficiency in performing simple, repetitive cognitive tasks, typically measured using tests of symbol recognition, coding, or visual scanning.
Psychoeducational Assessment #
An evaluation that combines psychological and educational testing to help understand an individual's cognitive, academic, and emotional functioning. Psychoeducational assessments are often used in educational settings to diagnose learning disabilities, identify giftedness, or develop educational plans.
Standard Score #
A normalized score derived from an individual's test performance, allowing comparison of their performance to a normative group. Standard scores typically have a mean of 100 and a standard deviation of 15.
Wechsler Adult Intelligence Scale (WAIS) #
A widely used intelligence test designed to assess the cognitive abilities of adults aged 16-90. The WAIS measures various cognitive abilities, including verbal comprehension, perceptual reasoning, working memory, and processing speed.
Wechsler Intelligence Scale for Children (WISC) #
A commonly used intelligence test designed to assess the cognitive abilities of children aged 6-16. The WISC measures various cognitive abilities, including verbal comprehension, perceptual reasoning, working memory, and processing speed.
Wechsler Preschool and Primary Scale of Intelligence (WPPSI) #
An intelligence test designed for children aged 2.5-7.5. The WPPSI measures various cognitive abilities, including verbal reasoning, nonverbal reasoning, processing speed, and working memory.
Working Memory #
A cognitive ability that represents an individual's capacity to temporarily store and manipulate information, typically measured using tests of digit span, spatial span, or listening recall.
