Few phenomena in psychology have been studied more than reaction time. However, while response latency now provides the basic data for research in many areas of cognitive psychology, little work has been done on the problem of incorporating response latency in the measurement of individual differences. A solution to this problem requires the…

Attempted to clarify issues raised by Block, Block and Harrington regarding the conceptualization, validity and interpretation of reflection-impulsivity. (Author/SDH)

Responded to the various arguments advanced by Kagan and Messer in their rebuttal to the authors' review and research focusing on the interpretation of the Matching Familiar Figures Test. (Author/SDH)

The examination of saccadic eye movements--rapid shifts in gaze from one visual area of interest to another--is useful in studying pilot's visual learning in flight simulator training. Saccadic eye movements are the basic oculomotor response associated with the acquisition of visual information and provide an objective measure of higher perceptual…

The manner in which instructions to respondents influenced the psychometric results of an affective instrument was examined. Undergraduate students enrolled in an educational measurement course were randomly assigned to either immediate response or careful response treatments. A fifteen-item attitude scale was administered to both groups. The…

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)

The relative importance of different cognitive subprocesses in Bender performance was studied with Black middle-class first graders. Results suggest that the Bender owes much of its clinical validity to loadings across all stages of human information processing. Kagan's hypothesis on conceptual tempo in Bender performance is also analyzed. (SJL)

Forty three-option multiple choice (MC) statements on a midterm examination were converted to 120 true-false (TF) statements, identical in content. Test forms (MC and TF) were randomly administered to 50 undergraduates, to investigate the validity and internal consistency reliability of the two forms. A Kuder-Richardson formula 20 reliability was…

It was hypothesized that, with stimulus words selected for familiarity and associative hierarchy, extreme responders give faster and more common or popular free associations than nonextreme responders. Results did not support this hypothesis. Predicted effects of stimulus word attributes were observed. (Author)

Judgments that favorably set an individual apart from others tend to be made more rapidly, suggesting that the self-concept is both an effective and a cognitive entity. Subjects rated the self-applicability of traits on a 100-point scale. As in other studies using dichotomous judgements, judgement speed increased with increasing self-applicability…

Describes study conducted with U.S. Marine Corps enlisted personnel to measure response time to computer-administered questionnaire items, and to evaluate how measurement of response time might be useful in various research areas. Topics addressed include mood states; the occurrence of straight lining; and experimental effects of sleep loss and…

The relationships between response latencies and accuracy on the matching familiar figures test (MFFT) and two gross motor tasks (batting or catching a ball) were studied in twenty-nine 9-year-old boys. Children were classified into four groups using a double dichotomy of response latencies and errors on the MFFT: reflective, impulsive,…

Detailed item analysis results for a form of the Scholastic Aptitude Test were examined for evidence of sex differences in test speededness. The conclusions were: (1) there was no evidence of appreciable differences in rate-of-work on any section of the Scholastic Aptitude Test; (2) there was some evidence that low-scoring females on the…

Recently, there has been a resurgence of interest in the use of response latencies in psychological assessment. Some research has suggested that response times associated with answering personality and integrity questionnaires may be useful in differentiating among honest responders and individuals who are lying. Using an experimental paradigm…
