Summary
The NIH Toolbox Cognition Battery includes language tests for assessing vocabulary and reading skills. These computer-adaptive tests show high reliability and validity in adults, supporting their use in evaluating language development across the lifespan.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Psychometrics
Background:
- Language is crucial for cognitive development, education, and life adaptation.
- The NIH Toolbox Cognition Battery (NIHTB-CB) includes language as a key subdomain.
- Assessing language functioning involves components like syntax and lexical semantics.
Purpose of the Study:
- To validate the English versions of the NIHTB-CB's picture vocabulary and reading recognition tests.
- To evaluate the reliability and construct validity of these language measures in adults.
- To examine age-related patterns in language development and stabilization.
Main Methods:
- Computer adaptive testing (CAT) was used for test administration.
- Item response theory (IRT) was employed for scoring.
- Validation involved comparison with gold-standard measures in adults aged 20-85.
Main Results:
- Both the picture vocabulary and reading recognition tests demonstrated high test-retest reliability.
- Good construct validity was observed when compared to established measures.
- Language scores aligned with expected age-related trajectories, showing growth and stabilization.
Conclusions:
- The NIH Toolbox language tests are reliable and valid tools for assessing vocabulary and reading in English-speaking adults.
- These measures can track language development across the lifespan, from early growth to adult stabilization.
- The NIHTB-CB provides valuable insights into language's role in neurological and behavioral function.

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

01:23Wechsler's Contribution to Measures of Intelligence
2.9K
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence...

Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing...

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

01:27Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

77.8K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...
