Gp. Aylward et al., RELATIONSHIPS BETWEEN CONTINUOUS PERFORMANCE TASK SCORES AND OTHER COGNITIVE MEASURES - CAUSALITY OR COMMONALITY, Assessment, 4(4), 1997, pp. 325-336
Relationships among continuous performance test, IQ, achievement, and
memory/ learning scores were explored in a clinical sample of 1,280 ch
ildren (M age = 9.4 years, M grade = 3.9). Intercorrelations among CPT
measures were significant, but modest. Correlations between CPT measu
res and IQ, achievement, and memory/learning scores were also signific
ant, but again generally weak. The CPT number correct scores were more
strongly related to other cognitive measures than were commission (i.
e., responding to incorrect stimuli) scores. The breadth and extent of
associations among the CPT measures and the various cognitive/academi
c tasks suggest that all, to some extent, require attention and inhibi
tion. The importance of routinely assessing attention and disinhibitio
n in psychological testing is discussed.
