The similarity match took longer than the identity match, and the difference in latency increased as the number of lines in the pattern increased. (Author)

Three experiments examined whether the phenomena of visual search for single characters (Sternberg, 1966) generalizes to word and word-category search when target and distractor sets had varied and consistent mappings across trials. Previous results were replicated. Four principles of search are discussed within a theory of automatic/control…

The Matching Familiar Figures Test assesses the dimension of reflection-impulsivity in children. This study compares responses of a single sample to the established norms and adds intelligence quotient (IQ) for classification purposes. Analysis indicates that IQ significantly correlates with both latency and errors. (Author/CM)

Examined whether children (ages 4-5) were, like adults, capable of using precued information to preselect a response and remember it briefly. Findings suggest that the 10 preschoolers could preselect a response and maintain it for about one second, but they had difficulty over a 3- or 5-second delay. (Author/SJL)

In these choice response keyboard tasks, older subjects detected and corrected their errors as efficiently as the young. Reaction time (RT) for error and error correction responses remained relatively constant with increasing age while RTs for correct responses and other, arbitrary, error-signaling responses markedly increased. (Author/SJL)

Results of a choice reaction time study indicated that nine mildly retarded junior high students appeared to be less sensitive than nonretarded controls to stimulus probabiity information, particularly under degraded stimulus conditions. (Author)

The relationship between latency to respond and performance on the ITPA Visual Association subtest was investigated for 50 preschoolers. Performance was a function of age and response latency. It was concluded that for children who don't have the appropriate search strategy, the visual association subtest doesn't give a valid assessment.…

Reber found that subjects given neutral instructions to memorize letter strings from a synthetic language learned more about the underlying grammar than those instructed to try discovering the rules for letter order. Two experiments explored the relationship between implicit and explicit processes in the acquisition of complex knowledge.…

Two experiments examined the role of presupposed (or old) and focal (or new) information in integrating sentences, by measuring comprehension time for various combinations of presupposed and focal information. (Author/AM)

A total of 12 second- and fifth-graders' semantic decision times for pictures and words were analyzed relative to the predictions derived from unitary- and dual-memory models. (MS)

Examined the effect of heart rate and behavioral measures of attention on infants' distractibility. Found longer distraction latencies during attentional engagement as defined by heart rate changes or behavior than for inattentive periods. Infants had longest distraction latencies when heart rate and behavior measures both indicated engagement.…

Examines the meaning of reaction time (RT) and the possibility that it may predict other cognitive and motor skills in the first year of life. Considers two competing models that specify the information-processing components underlying RT performance. Describes the neural data needed to definitively choose between the models and considers…

Sixty-four adults were tested on simple addition and multiplication problems presented in Arabic digit or English number-word format. Overall, response times and error rates were much higher with the word format, but more important, presentation format interacted with arithmetic operation and problem size. (DR)

Correlations among peripheral nerve conduction velocity (NCV), brain NCV, simple and choice reaction times, and a standard measure of intelligence were investigated for 200 male college students. No correlation was found between any arm NCV and the intelligence score. Neurophysiological bases of human information processing and intelligence are…
