Purpose: This study investigated the relationship between hearing loss and memory and attention when nonverbal, visually presented cognitive tests are used. Method: Hearing loss (pure-tone audiometry) and IQ were measured in 30 participants with mild to severe hearing loss. Participants performed cognitive tests of pattern recognition memory,…

In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…

A study investigated developments in reasoning and memory as reflected by the discovery strategies of children taking part in a manipulative categorization and recall task. A total of 40 children (8 each of 18, 24, 30, 36, and 42 months of age) participated. Stimulus materials consisting of blocks, toy plates, discs, and plastic trees were…

Certain aspects of the performance of adults on verbal reasoning tasks were studied. The four main objectives of the study were: to develop a self-instructional booklet for use in teaching adults the functional rules of classification; to construct a reliable instrument for use in assessing the capability of adults to perform verbal classification…

This summarizes a study designed to provide a basis for researchers who study measurable areas of human performance or attempt to conceptualize and develop a theory and structure of abilities. Specifically, this study was directed toward the identification of tests that can serve as markers for well established cognitive factors. (Author/CTM)
