Boys (N=55) aged 8-11, categorized as impulsives by the Matching Familiar Figures test, participated in a study comparing the effects of three different techniques, designed to change an impulsive cognitive style on response accuracy and response latency. Subjects trained to increase response latency did show a significant increase in latency.…

Longstreth's critique of Jensen's research on the relationship of IQ to individual differences in visual reaction time (RT), measured in the Hick paradigm, is said to have numerous errors of fact and interpretation, some trivial and some of theoretical importance. (Author/LMO)

Measures of verbal intelligence and abstract reasoning were taken on a group of 31 college-aged and 32 elderly adults, together with mental-processing rates associated with choice reaction time, primary memory scanning, and lexical decoding. Group means showed that verbal IQ and lexical decoding were intact in the elderly subjects. (Author/LMO)

Relationships between intelligence test scores and measures derived from reaction time and perceptual speed procedures were investigated. Only three reaction time measures produced correlations greater than .25 with a general intelligence factor. Test-retest reliability of reaction time measures was low. The reaction time-intelligence relationship…

The data indicated that disadvantaged children required more time to process visual information than did middle-class children, but the processing speed for the 2 groups tended to become more similar as grade level was increased. (Author)

Total reaction time for dyslexic children was found to be longer than for normal children, suggesting that a modification of the study task might be useful for the early prediction of reading disability. (GS)

Exercise may postpone the deterioration in response speed that generally appears in the motor system of the aging by maintaining the nigrostriatal dopaminergic system in the brain. Exercise may also ameliorate symptoms of Parkinson's disease. Results of laboratory studies involving animals and rats are reported. (Author/PP)

Gender schema theory proposes that sex typing derives from gender-based schematic processing, particularly from the self-concept itself being assimilated to the gender schema. In two studies sex-typed individuals were found to have a greater readiness to process information (including information about the self) in terms of the gender schema.…

Three evaluations (general preference, balance, and dynamics) were made for paintings presented simultaneously in artist-created and mirror-image views. For short (5 second) exposures, results showed consistent selection over diverse contents of paintings with a left-to-right figure sequence. Implications for perception and aesthetics are…

Describes various performance measures used in a study to investigate the relation of performance pace to age and information processing ability. Test results indicated no differences in performance pace but differences in performance quality between young and older individuals, with implications for hiring and training older workers. (MF)

A uniprocessor, unidimensional model, based on Krueger's noisy-operator theory, was fitted satisfactorily to data from four published studies of tone comparison. The model predicts faster response time on different judgments because of heterogeneity of difference. (Author/CP)

The purpose of this study was to determine if reaction time in the peripheral visual field and size of the functional visual field were altered by augmented levels of physical stress while performing on a bicycle ergometer. (JD)
