Response latency models for signal detection.

Abstract: Describes 2 contrasting models for response latency in the yes-no signal detection situation and outlines their main characteristics. The 1st model is a generalization of the notion that latency in detection is some inverse function of distance from the criterion; the 2nd proposes that instead of a single observation on any 1 trial the S makes multiple observations and a count of these observations determines the response and its latency. Although the predictions of the models are similar in many respects, there are some points concerning the ordering of mean latencies, reaction time receiver operating characteristic curves, latency-probability relations, and the constancy of d' which differentiate them. Particularly important, the multiple observations model predicts that response bias and sensitivity are interdependent. The possibility of multiple observations in detection is briefly considered.

A study of the H-reflex by single fibre EMG.

Abstract: The latency of consecutive H-reflex responses of single human triceps surae motoneurones varies up to 2,500 μs. A large part of this variation was shown to occur at the synaptic transmission. A moderate increase in stimulus strength from the threshold value shortened the mean latency and reduced the latency variation, presumably as a result of spatial summation of excitatory inputs. Further increase to maximum strength lengthened the mean latency, increased the variation, and resulted in a dropping out of some responses which was not produced by collision by antidromic impulses. These effects are believed to be due to an active inhibition. Changes of the latency were also obtained by Jendrassik9s manoeuvre and facilitatory and inhibitory conditioning stimuli.

The Latency of the Skin Resistance Response and Reaction Time

Abstract: Skin conductance level (SCL) and skin resistance response (SRR) latency to a foreperiod warning light were shown to be related to a measure of simple reaction time performance. Other physiological measures monitored immediately prior to the task were not related to performance nor were they interrelated. Speculation is offered on the possible mechanism whereby a central facilitation system is related to SRR latency and to performance.

Response Latency as a Correlate of Individual Differences in Retention.

Abstract: 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 found that good retention'students demonstrated substantially longer latencies during acquisition than poor retention students. The investigators attributed this finding to the efficient employment of organizational strategies on the part of the good retention students. The investigators concluded that these data would indicate that the practical utility of response latency may be limited to situations in which a number of responses can be averaged to measure a characteristic of the learner rather than a characteristic of his momentary learning state.
