Abstract
The interference condition of the Brown–Peterson task and the auditory consonant trigrams test was designed to evaluate working memory in that it required a division of attentional processes to complete two cognitive tasks. However, the specific cognitive functions contributing to the performance of this interference task have yet to be determined. The objective of this study was to determine what other tasks are comparable to the Brown–Peterson task and conduct an exploratory factor analysis that included the measures from the Brown–Peterson task and other neuropsychological measures. A neuropsychological battery was administered to younger participants (n = 107, mean age = 20.83) and older participants (n = 93, mean age = 70.14). Factor analysis yielded a two-factor solution. Performance after the intervening serial subtraction task loaded on an auditory/visual working memory and complex attention factor and had common loadings with working memory subtests of the WAIS-III and the spatial span subtest of the WMS-III. Results suggest that the performance after the intervening serial subtraction task evaluates dual information processing, complex attention, and working memory.
The California Consonant Test© (CCT) is considered a word recognition (or speech discrimination) test. It is a closed-set word recognition test. The patient is given a paper score sheet with four multiple choices per item. He or she is asked to check the item heard on the recording. Watch the video! (See below.)
The California Consonant Test© is particularly sensitive to high frequency hearing loss and is, therefore, considered to be useful in hearing aid evaluations. The CCT consists of two 100-word lists. This test does not correlate highly with “phonetically balanced” word recognition tests such as the W-22 or NU-6, nor does it correlate with degree of hearing loss. Therefore, the CCT cannot be employed as a substitute for the more popular word recognition tests. Administration time is from 15-30 minutes.
