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)

Reports a series of three exploratory studies. (WY)

Concludes that children, as well as adults, are able to expand or contract the breadth of their attentional focus in accordance with task demands. Suggests there is a developmental change in the efficiency with which a stimulus presented in an otherwise empty field can be located. (Author/RH)

Presents preliminary data on how, during the execution of visually guided hand movements, differences in response time between children with and without signs of minor neurological dysfunction may be related to differences in the spatio-temporal organization of their movements. (MP)

Forty-eight female university students participated in a reaction-time experiment in which challenging goal instructions were manipulated under conditions of minimal feedback. Findings extend Locke's views of the effects of personal goals on subsequent performance to applications involving minimal implicit knowlege of results. (Author/MP)

A method is developed for estimating the response time distribution of an unobserved component in a two-component serial model. The estimate of the component's density function is constrained to be only unimodal and non-negative. Numerical examples suggest the method can yield reasonably accurate estimates with sample sizes of 300. (Author/CTM)

In choice reaction time (RT) tasks, the response of the appropriate finger by mentally retarded Ss is often accompanied by associated movements of responding and nonresponding fingers. To determine the effects of such associated movements, RTs were compared in two conditions with 10 mentally retarded adults. (Author)

Short rapid movements of great precision increase programming time for motor reaction. (JD)

A theoretical interpretation of the stimulus familiarization effect was explored in three experiments with 6- through 7-year-old children. (Author/SB)
