Empirical evidence collected so far has revealed that the bilingual advantage cannot be reduced to a single component of the executive functioning, and point to the need to understand the effects of bilingual experience on cognition as influencing a wider family of mental processes, including, but not limited to, cognitive control. The present…

The study explored various facets of the intuitive style and its relevance to learning and education from a dual-processing perspective, namely how it relates to other style constructs (analytical; visual and verbal; local and global), gender, and superstitious reasoning and how these are likely to impact upon learning in educational and…

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,…

Just as the Raven Progressive Matrices Test was uncorrelated in this sample with other measures of intelligence so was it much less well predicted from several information processing measures. It was found that verbal performance, indicated by a vocabulary score, was highly predictable from measures of information processing. While preserving…

Compares performance of children (N=19) with nonverbal language disabilities to a group of children (N=16) with language learning disabilities using the Kaufman Assessment Battery for Children (K-ABC). As hypothesized, children with nonverbal learning disabilities were found to have significantly higher simultaneous successive processing scores.…

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…

Findings indicate that (1) development of probability reasoning can be shown by an increasing monotonic trend with age, (2) verbal tests assess different aspects of this development than do nonverbal tests, (3) Piaget's ontogenetic age brackets are accurate, and (4) sex and intelligence are not significant variables.

A study of the responses made to problems selected from Raven's Progressive Matrices showed differences in the kinds of errors typically made by eighteen-year-old students. Nine problems were used and the 68 subjects were told to draw their answers on the answer sheets. There were two trials per puzzle. A classification system, devised for errors,…

This study sought to determine whether there exist performance distinctions between artists and nonartists on specific two- and three-dimensional nonverbal problems. The factorial structure of scores on ten nonverbal ability tests was analyzed to identify mental process differences between the two groups. (Author/SJL)

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…

The complex and multi-faceted nature of the cognitive process of reasoning is discussed. The factor-analytic history of the isolation and definition of the three most important currently recognized reasoning factors (general reasoning, induction, and logical or deductive reasoning) is traced through the psychometric literature, and the…

Replicating previous findings that the inability to "shift" conceptual attitude on the Weigl is consistent with indices associated with cortical dysfunction, the Weigl is shown to possibly serve as a nonverbal instrument to assess cortical dysfunction where inability to "shift" appears to tap a dysfunction in symbolic rather…

The effects of modeling and corrective feedback on the conservation of equalities and inequalities were studied with items spanning three stimulus dimensions (length, number, and two-dimensional space). Observation of a model, correction training (joining positive feedback with verbal rule provision), and the combination of observation and…
