IQ in childhood and the metabolic syndrome in middle age: Extended follow-up of the 1946 British Birth Cohort Study

IQ in early adulthood has been inversely associated with risk of the metabolic syndrome in midlife. We tested this association in the British 1946 birth cohort, which assessed IQ at age eight years and ascertained the metabolic syndrome at age 53 years based on modified (non-fasting blood) ATPIII criteria. Childhood IQ was inversely associated with risk of the metabolic syndrome, but this association was almost entirely mediated by educational attainment and achieved occupational social class. This may be consistent with a pattern where childhood IQ is strongly associated with outcomes that reflect neurological disorder, such as the degenerative dementias, but less so with common chronic physical diseases of ageing.     

Phonemic imperception in aphasia

This study investigated characteristics of 14 aphasics with impaired phoneme discrimination identified from a population of 100 patients with left hemisphere lesions. All patients with impaired phoneme discrimination were significantly impaired in aural comprehension, but many showed intact sound recognition and some showed normal reading comprehension. Defects in phoneme discrimination were typically seen in the acute stage of aphasia resulting from stroke; and in most instances, defects in phoneme discrimination were no longer apparent 4 months postonset. All patients who recovered normal phoneme discrimination also made significant improvement in aural comprehension. The findings support the concept that some aural comprehension defects result from a specific disturbance in phoneme discrimination.     

Effectiveness of a brief counseling intervention in stimulating vocational exploration

The intervention procedures used in this study, a brief report of vocational interest scores and small group sessions on vocational planning, were designed to encourage girls to consider the full range of occupations, unrestricted by sex-role stereotypes. In each of three schools, ninth-grade girls with average academic ability or above were randomly assigned to an intervention group (N = 195) and a control group (N = 195). Analyses of 1- and 3-month outcome data indicated that the intervention stimulated occupational exploration and increased congruence between occupational preferences and measured interests. Outcomes differed according to interest type, thus suggesting that certain students may need more counselor attention than others.     

Qualitative aspects of pantomime recognition defect in aphasia

This study investigated the performance pattern of aphasic patients on a pantomime recognition test in which one of the four response alternatives was an object semantically related to the correct choice. Aphasics with defective pantomime recognition made 71% of their total errors on the semantic foils, and for the majority of such patients, semantic errors represented 80 to 100% of total errors. Only aphasies with objective evidence of confusion failed to make highly frequent semantic errors. The findings suggest that most aphasies who fail pantomime recognition are impaired because of semantically vague understanding of the pantomimes' intended meaning rather than complete lack of understanding of the pantomime.
