Article evaluated research studies completed by Baddeley-Ecob concerning the relationship between reaction time models and recognition memory. (Author/RK)

This study investigated: (1) whether infants can develop expectations for events that alternate along the vertical axis; and (2) whether infants who form expectations with one action set can transfer them to a different action set--that is, from vertical to horizontal eye movements. A total of 32 infants of 3 months of age saw one of two picture…

The percentage of rapid eye movement (REM) during sleep is substantially greater in neonates (infants in first month after birth) than in other children or adults. It was hypothesized that REM rate may decline as rates of many response sequences do when repeatedly elicited. Electrical recordings of eye movements were obtained from a 3-day-old male…

Reports the recent work by Arthur Jensen correlating reaction time to intelligence. Jensen hypothesizes a noncognitive mechanism for superior reaction times. (MDR)

Jensen has reported reaction-time (RT) studies indicating that various parameters correlate significantly with IQ. Two parameters of interest are slope of RT across set size and increasing correlations of RT with IQ as set size increases. After reviewing these studies, the author concludes that Jensen's claims are unwarranted. (Author/BW)

Nine children with Down's syndrome were compared to two groups of nonretarded children, one similar in CA, the other a chronologically younger group of similar MA. The event-related brain potential and reaction time results indicated that Downs syndrome Ss processed some types of auditory information more slowly than the other groups. (Author/CL)

A procedure for using MEL2 (Version 2.0 of Microcomputer Experimental Laboratory) and FontWINDOW to present special characters and symbols in computer-controlled reaction time experiments is described. The procedure permits more convenience and flexibility than in tachistocopic and projection techniques. FontWINDOW allows researchers to design…

The ability of M. Levine's subset-sampling assumptions to account for the decrease in response latency following the trial of the last error was investigated by employing a distributed stimulus set composed of four binary dimensions and a procedure which required Ss to make an overt response in order to sample each dimension.

Results obtained from adults and 8-, 10-, 12- and 14-year-olds indicate that children's advantage for repeated stimuli in reaction-time tasks and the decrease in magnitude of the repetition effect as age increases can be attributed to repetition of the same stimulus, rather than repetition of the same response.

Response times among four starting techniques (cross-over step, jab step, standing sprinter's start, and momentum start) were compared. The results suggest that the momentum start was the fastest starting technique for optimum speed in running bases. (FG)

Secondary task performance was used to evaluate the attentional demands of encoding the first letter in a sequential letter-match task. Unlike earlier studies, comparing secondary task performance between two primary task conditions indicated that letter encoding involves attention. Performance during the intertrial interval varied with subjects'…
