Used a reaction time paradigm to examine the behavior of young children and adults in a picture-identification task where the pictures presented were from both the child's and the adult's point of view (e.g., the underside of a table as well as the eating surface). (JMB)

Correlations between elementary sensory tasks and IQ scores support Galtonian theories of intelligence, which emphasize speed of signal encoding and transmission in the nervous system. Research involving 73 male Navy recruits indicates that such theories are warranted only when elementary tasks are viewed separately. Task complexity in…

By comparing the profile of "g" loadings for a set of psychometric test scores, it is shown that general intelligence is related to timed performance measures from perceptual-motor tasks, more strongly on more complex tasks. The profile of the "g" loadings was predictable from the response-time (RT) psychometric test time correlations for four RT…

This article considers a set of assumptions about the antecedents and consequences of effort expenditure when a subject is engaged in achievement-oriented behavior. It examines both static models (level of effort is constant over trials) and dynamic models (preceding task outcome may influence current level of effort). (Author/BW)

Equally divided by sex and distributed equally across fourth/fifth, eighth/ninth, and college grade levels, 144 subjects performed a mental rotation task under instructions emphasizing either accuracy or speed of response, or both. Instructions had large and consistent effects on speed of response but were not as uniformly effective in their…

Reports the measurement of response latencies and the recording of eye movements in a task in which children of approximately five-and-a-half years counted one to eight dots presented in different configurations. (Author/RH)

Examined the category structure of joy and shame emotions by having college students (N=40) judge slides of human faces. Results supported the family resemblance-prototype process in that the higher the typicality, the shorter the reaction time and showed that the more intense (typical) expressions were recognized more accurately. (LLL)

Attempts to isolate lexical access latencies by measuring word-naming times in two conditions: (1) words were preidentified and had only to be pronounced on signal; (2) words had to be both identified and pronounced. Results strengthen the conclusion that vocal programing is exempt from the age declines seen in other sensory-motor tracts.…

Discusses two experiments into a subject's "Different" reaction time in judging whether two test instances are members of the same semantic category. (Author/RM)

In this study four methods were compared for setting a response time threshold that differentiates rapid-guessing behavior from solution behavior when examinees are obliged to complete a low-stakes test. The four methods examined were: (1) a fixed threshold for all test items; (2) thresholds based on item surface features such as the amount of…

The list-scanning experiments first described and studied by Sternberg have raised some important and interesting questions about memory function and the close and subtle relationship between memory and attention. This paper presents an attempt to explain these findings. (Author/RK)

The present research deals with the PRP effect as it occurs in a task involving response uncertainty that must be resolved on the basis of a decoding of each signal. (Author)

Results indicated that subjects in each source of blame group responded with significantly less amplitude and speed following interruption than noninterruption. (Authors)

This study investigated the effects of 15 second client response latencies upon the speech and silence behavior of four experimentally naive counselors in advanced training. The results indicate that a coached client was able to effect change unobtrusively in the speech and silence behavior of counselors. (Author)

Designed to reassess the relationship between response speed, errors, and IQ for both sexes, and to evaluate the findings in relation to the overall pattern of data accumulated from previous investigations. (Author/AJ)
