An examination of the relationship between response latency during paired-associate learning and the subsequent retention in a computer assisted instruction (CAI) program was conducted in this experiment. Forty-five college students were presented nonsense syllables that had to be associated with key symbols on a response panel. The experiment…

Three pairs of spatial antonyms (higher than/lower than, above/below, and rising away from/falling away from) were used in a task in which subjects judged whether a sentence accurately described a previously presented pictorial relationship. Subjects' reaction times were used as the dependent measure. Since all three word pairs were used…

Subjects compared pairs of nonconcrete and "nonimageable" words along a dimension which has no physical analog--the evaluative dimension of the semantic differential. Their reaction time to do so was an inverse logarithmic function of the difference between the numerical "goodness' values they had assigned to the words. (Author/RM)

The decision time (reaction time [RT]) and movement time of retarded persons as a function of the amplitude and precision of a discrete movement in both simple and choice RT paradigms was examined in two studies involving 24 mentally retarded adults. (Author)

The contributions of specific motor-coordination disabilities and general slowness of motor function to the choice reaction times (RTs) of 22 mildly retarded adults were examined in two experiments. (Author)

When adults judge which of two digits is numerically larger, their response times decrease linearly with the numerical difference. For fourth- and seventh-grade children, the slope of the function relating judgment time to numerical difference is similar to that of adults, but much steeper for kindergarten and first-grade children.

Task performance of 12 pervasive hyperactives and controls (ages 8-13) was studied in a divided attention reaction time experiment. Hyperactives were slower than controls, had more variable reaction times, and made more frequent errors. Task inefficiency in hyperactives could not be explained by a divided attention deficiency or impulsive…

Two experiments investigated sentence context effects on the naming times of sentence completion words by third-grade children and college students. The semantic acceptability of the word in the sentence context had a much greater influence on children's word identification times than adults'. (Author/CB)

Studies 45 low-medical-risk preterm infants and 23 healthy term neonates, revealing that preterms are more wakeful but not more visually responsive than full-term infants. Intrameasure correlations suggest that the organization of wakefulness and visual responsiveness is different in full-term neonates and in preterms at expected date of birth.…

Infants, preschoolers, and adults were tested to determine the shortest time interval at which they would respond to the precedence effect, an auditory phenomenon produced by presenting the same sound through two loudspeakers with the input to one loudspeaker delayed in relation to the other. Results revealed developmental differences in threshold…

Two samples of adult subjects of reasonably average intelligence were given IQ tests and a series of reaction time tests using 0, 1, 2, and 3 lists of information in a Hick paradigm. (Author/LMO)

Two status variables were examined in an academic setting through monitoring of reprint-sending behavior; requester's sex and academic ranking had no significant effect on total number of responses received. Males, however, received responses significantly faster than females, and male authors were more likely than female authors to honor…

Two studies involving children (mean age of 10 years) and adults investigated the effects of visual stimulus onsets and offsets on the latency of saccades to peripheral targets. Results were interpreted as indicating that, while stimulus intake processes have a greater interference effect on children's eye movements, oculomotor processes are…
