Proposes a new measure of the citation speed of scientific publications based on a stopping time approach. The stochastic process approach in bibliometrics is described, mean response time (MRT) is discussed, harmonic mean response time (HMRT) is explained, and examples are given. (six references) (LRW)

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

A task involving movements with either hand to near or far targets was employed with 16 adults with mental retardation (9 of whom had Down's syndrome). Specific features of the movement were precued. Both groups were able to use advance information to reduce movement preparation time and were not limited by a fixed-order movement preparation…

Children and adults were tested on a mental rotation task in which letters were presented in different orientations. The task was performed by itself or with a memory task. Results indicated that the relation of response time to stimulus orientation in the rotation task was the same in both conditions. (BC)

Administered 2 elementary cognitive task (ECT) tests and 2 psychometric intelligence tests to 169 monozygotic and 131 dizygotic pairs of twins in Germany. Reaction times correlated negatively with psychometric intelligence, and habitability estimates were substantial for both psychometric intelligence and reaction times on the ECTs. Multivariate…

Investigates perception by manipulating the requirement to discriminate between kinesthetic stimuli and the translation process by manipulating stimulus-response compatibility. Results indicated that the kinesthetic reaction time of clumsy children was found to be longer than that of controls. Claims that the findings may indicate that clumsiness…

Effect of a 4 s constant time delay procedure on motor skill completion durations was examined. Participants were four adolescents with severe mental retardation. Results indicated that data patterns between adjacent baseline and intervention phases were visually different and statistically significant in the direction of less time. (Contains…

A study investigated phonological processing skills of 28 undergraduates with dyslexia. When compared to 31 controls, subjects performed significantly less well on standardized measures of reading and spelling but in the average range. Controls, however, performed significantly better on all phonological processing measures, particularly those…

Research indicates that attentional deficits exist in aphasic individuals. However, relatively little is known about auditory vigilance performance in individuals with aphasia. The current study explores reaction time (RT) and accuracy in 10 aphasic participants and 10 nonbrain-damaged controls during linguistic and nonlinguistic auditory…

ourse comprehensionEvidence conflicts as to whether adults with right hemisphere brain damage (RHD) generate inferences during text comprehension. M. Beeman (1993) reported that adults with RHD fail to activate the lexical-semantic bases of routine bridging inferences, which are necessary for comprehension. But other evidence indicates that adults…

Van Breukelen (this issue) provides an approach to using both response time (RT) and accuracy for (1) measuring latent abilities of participants even when they may trade speed for accuracy, and for (2) providing insight into the psychological processes underlying task performance. In this commentary, I focus on the second of these aims and assess…

Participants acquired spatial knowledge of a fictitious island by studying either (a) a complete physical map, (b) a sequence of part maps each showing the outline of the island and a subset of the landmarks, or (c) a sequence of sentences each describing a part map. During test, they verified the direction between 2 landmarks. Spatial knowledge…

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N=245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level…

One purpose of the McCloy Lecture is to remember C. H. McCloy. Previous presenters have provided excellent summaries of McCloy's career (Christina, 1999; Lee, 2002; Thomas, 2000) and highlighted his scientific and academic contributions to our field and the organization now known as the American Alliance for Health, Physical Education, Recreation…

Four hundred and forty-one undergraduates at a large southeastern university completed a confidential anonymous 38-item questionnaire designed to assess student attitudes toward the elderly. The data revealed several significant gender differences including the age at which a person becomes "old" (men select a younger age), strength (men see less…
