Effects of Systematic Categorization Training on Cognitive Performance in Healthy Older Adults and in Adults with Traumatic Brain Injury

Table 6

Pearson correlations between constructed composite scores and categorization measures (older adults only).

Executive Functioning composite	.398	.446	.365	.342	.180	.244	.510	.047	.141	.458
Perception/Visual Processing composite	.673	.422	.227	.824	.120	.740	.503	.064	.468	.310
Conceptual/Reasoning composite	.595	.437	.614	.721	.290	.541	.449	.064	.401	.777
Organization/Attention composite	.290	.177	.480	.440	.424	.484	.463	.214	.174	.356
Global Cognitive composite	.609	.517	.343	.864	.096	.443	.537	.004	.503	.596

Note: Executive Functioning composite does not include the following Wisconsin Card Sort Measures: Total Number of Categories, Trials to 1^st Category, and Failure to Maintain Set. Posttests and pre-post difference scores include the experimental older participants only. ; . + indicates partial correlations holding the corresponding pretest performance as a covariate.
