Time perspective in vocational maturity and career decision making

This study investigated the hypothesis that time perspective is a component in vocational maturity and career decision making. Ninety-seven college freshmen responded to two measures of time perspective and seven measures selected to represent attitudinal vocational maturity, cognitive vocational maturity, and career decision making. The nine variables were intercorrelated and the resulting matrix was subjected to alpha factor analysis. Three factors were extracted and titled Attitudinal Vocational Maturity, Cognitive Vocational Maturity, and Career Decision Making. As predicted, time perspective was a component in the Attitudinal Vocational Maturity and Career Decision-Making factors. The results supported the hypothesis and specifically linked time perspective to planfulness and degree of indecision.     

A neuronal model for syllable representation

A speculative neuronal template, equivalent to canonical syllable forms and independent of segmental representations, is offered to help account for (1) the inviolate nature of phonotactic constraints in aphasic speech output, and (2) left hemisphere specialization for speech sound access and output. The model, which attempts to relate plausible neuronal systems to linguistic function, is based on cell assemblies that are thought to develop by way of genetic predisposition and ontogenetic language experience, into configurations that can represent canonical slot positions for the consonants and vowel comprising a syllable. The syllable is assumed to be the basic organizational rhythmic unit for serial concatenation of sublexical segments. A scheme for neurological differentiation of vowels and consonants is offered. Phonotactic constraints can become "hard-wired" to help create the automaticity underlying phonological sound organization. Testable predictions are offered to substantiate the claims of the model.     

Recovery from aphasia: Spontaneous speech versus language comprehension

Seventy-four aphasic patients, subdivided into four groups (fluent, mixed, nonfluent, and severely nonfluent), were tested three times in the course of 1 year to assess recovery of spontaneous speech and sentence comprehension. Although 12 of the 28 spontaneous speech variables employed showed significant time changes, some of these changes indicated improvement and others deterioration. There was no overall clinical improvement in spontaneous speech in any group. On the sentence comprehension tests, however, all four groups did show considerable, significant improvement. There were no qualitative or quantitative differences among the groups in the course of recovery, despite the fact that the groups differed in the severity of aphasia as well as on the fluency dimension. In certain patients there was also some improvement in spontaneous speech, but this did not in most cases correlate with an improvement in either fluency or sentence comprehension. Possible reasons why receptive abilities improved more than expressive abilities are discussed.     

Cluster analysis in school psychology: An example

This investigation demonstrates the use of Ward's method of cluster analysis to uncover the underlying classification structure in a group of children (N = 200) referred for psychological evaluations by their public school teachers. Data were acquired on children's intellectual development, academic achievement, and social adjustment. The cluster solution identifies six groups of children which are statistically distinct. All three measurement areas are important in distinguishing among the different groups. The six-group solution accounted for appreciable amounts (95%) of the variability in the three measurement areas. Implications for psychologists working in the schools are discussed.     

Asymmetries for the categorization of kanji nouns, adjectives, and verbs presented to the left and right

Kanji is one form of written Japanese in which the symbolic/analytic characteristics of language are dissociated from systematic phonetic characteristics; as such, it makes possible a more careful test of which aspect of language is responsible for the frequently observed superior left-hemisphere performance. In this study, subjects were asked to categorize tachistoscopically presented kanji as nouns, adjectives, or verbs. The previously reported (Hatta 1977, Neuropsychologia, 15, 685–688) left-visual-field advantage for kanji was found only in the case of nouns. Adjectives and verbs were processed more rapidly and correctly in the right visual field.
