Psychometric assessment of cognitive process
Answers
A measurement and psychometric examination of a set of cognitive tasks was carried out. A critical part of this analysis involved investigation of the stability of latencies and number correct scores over a two-week time period. Relations with standardized test scores and scores on a variety of ability measures were also investigated. Finally, the tenability of considering data from individual paradigms as narrow components of “g” and aggregating latencies to form meaningful composites with significant relations with g was investigated. Results indicate moderate to high reliabilities for most of the tasks investigated. Stabilities were found to be low to moderately high. Significant and compelling levels of covariation were achieved from the aggregation of scores, indicating clear promise for the continued investigation of this approach. Findings are discussed in the realm of the critical need for evaluating psychometric and measurement properties of cognitive tasks used in individual differences research.
