Deliberate commission of category mistake. Crombie vs. Ryle

Crombie's acceptance of the deliberate commission of a category mistake in his defense of the meaningfulness of theological statements raises a pointed challenge to the philosophy of Ryle which seems not to have been specifically addressed in subsequent literature. We review the analysis which leads Crombie into it, including concepts of anomaly, deficiency, affinity, and inadequate notion, noting basic differences in method and attitude from Ryle. We express our own agreements and disagreements in keeping with an overall concern for the preservation of rationality in this sphere of language, finding acceptable distinct contributions to that end from both.     

A fuzzy system for mapping worker attributes to tasks

We developed a prototype of a rule-based expert system that facilitates a mapping from tasks comprising a job to the knowledge, skills, and abilities (KSAs) ostensibly required to perform the tasks. A variant of fuzzy logic was employed in the inference process. Signal detection theory was used to evaluate the performance of the system. The results indicated that the system performed well in terms of its ability to discriminate between the KSAs that are required of a task and those that are not. The discussion focuses on implications of the system and its use as an intelligent assistant in human resources planning.

'But they aren't motivated …' issues concerned with encouraging motivation for change in families

This article is an attempt to provide some frameworks for understanding aspects of the context of families which support or constrain motivation for change. A theme of the entire paper is that ambivalence is normal and that it is therefore useful to regard families both as motivated to change and motivated to maintain stability. Part I focuses particularly upon family–referrer– therapist relationships and Part II upon family–therapist relationships. Part I begins with an exploration of the idea of motivation as a process and outlines the usefulness of the concept of ambivalence. Its main focus however is upon the importance of considering referrers when attempting to assess the motivation of family members for change.
Part II considers the relationship between the family and the therapist and takes account of some important aspects of the contexts of both. It ends with a summary of some experiential exercises which enable one's personal understanding of motivation issues to develop.     

Individual and group differences in intelligence and speed of information processing

A battery of eight different reaction time (RT) tests, measuring the speed with which individuals perform various elementary cognitive processes, and a group test of scholastic aptitude (the Armed Services Vocational Aptitude Battery, ASVAB) were given to 50 black and 56 white male vocational college students. The regression of the general factor scores of the ASVAB on the RT measures yielded a shrunken multiple correlation of 0.465. Although discriminant analyses, when applied separately to the ASVAB subtests and to the RT variables, showed highly comparable overall discrimination (over 70% correct classification) between the black and white groups, factor scores derived from the general factor (labeled ‘speed of information processing’) of the RT battery show only about one-third as large a mean black-white difference as the mean group difference on the general factor scores derived from the ASVAB. Comparisons were also made between the 106 vocational college students and 100 university students of higher average academic aptitude who had previously been tested on the same RT battery (Vernon, 1983a). These groups showed marked differences on the RT variables, the largest differences occuring on the tests that required more complex cognitive processing. The more complex RT tests also correlate most highly with the psychometric measures of ability within each group. The results are consistent with the hypothesis that individual differences and the mean differences between groups in psychometric abilities and scholastic achievement are related to differences in the speed of information processing as measured in elementary cognitive tasks.     

Endemic images and the desensitization process

Forty-eight test-anxious subjects were selected and randomly assigned to one of three treatment conditions. The subjects in the first group were asked to imagine a series of images that reflected relaxing motifs and these images were counterposed with a series of items from a test-anxiety hierarchy. The second group received a course of group systematic desensitization. The third group (control) was asked to “think about relaxing” as recorded chamber music was played. Two one-way Analyses of Variance (ANOVAs) and a series of Scheffé multiple comparisons revealed that the subjects' post-therapy levels of anxiety as measured by the Suinn Test Anxiety Behavior Scale (STABS), as well as their grade point averages (GPA) were significantly different under the endemic image and control procedures. Significant differences were also observed for these measures when the scores of the systematic desensitization and control groups were compared. No significant differences were observed between the post-therapy scores of the endemic image and systematic desensitization groups. The utility of the endemic imagery treatment for clients who are unable to undergo deep muscle relaxation because of physical infirmities, for example, cerebral palsy, is noted and a call for more extensive research is made.     

INTELLIGENCE,COGNITIVE STYLES,AND BRAIN LATERALIZATION

The concept of intelligence as a kind of mental power is criticized, since it is essentially static. Many authors wish to substitute the concept of processes or styles of thinking and learning, which might be developed by appropriate training. But there is no consensus as to which styles are of major importance in intellectual growth, and few of those suggested can be assessed objectively. They resemble the historical notion of types; and like types, they may be weak in internal consistency and generalizability. Some types which are defined by psychometric variables or factors are more promising. Currently the contrast between left brain and right brain functions is over-popularized. But it is associated both with verbal vs visuospatial abilities, and with analytic-sequential vs holistic processing. The right brain has been credited with a wide range of other functions for which there is little evidence, e.g., intuition, creativity, meditational trance states, etc. Findings from studies of brain-damaged or commissurotomized patients, and experiments with normal subjects, are outlined. The dichotomy is not the same as Das' simultaneous vs successive, Freud's primary vs secondary processes, Witkin's field independence, or Guilford's convergent vs divergent. Certain implications for education, for mental testing, and for cross-cultural research are discussed.
