Reaction Time Study

Previous studies have raised the question of the validity of using only hospitalized Ss as controls when the results are generalized to a non-hospitalized population. Twelve male hospitalized Ss and 12 male non-hospitalized Ss participated in a reaction time study using the visual and auditory modalities under constant 6-, 9-, and 15-sec. foreperiod conditions. The data showed significant differences between groups in all foreperiods with the auditory stimuli and the 15-sec. foreperiod with the visual stimulus. Results are discussed in terms of the use of hospitalized patients as controls in research and the differential effect of foreperiod and modality on the two groups studied.

Verbal Messages

It was thought that the physical aspects of auditory stimuli were possibly transmitted via separate pathways from those transmitting the verbal aspects. Three experiments were designed to test this hypothesis. In these experiments subjects had to perform a shadowing task and had to respond simultaneously on response keys to pips superimposed in either ear on verbal messages. The response to these pips was of increasing complexity, in that it was a simple reaction time which was measured in the first experiment, a choice reaction time in the second experiment and a more complex choice reaction time in the third experiment. Subjects were able to perform these tests although the increasing difficulty was reflected in longer reaction times and more errors. The reaction times to the pips presented to the ear which was not being shadowed were slower, and the errors, made to pips in both channels, were “false positives” rather than errors of omission. These results were taken as favouring the hypothesis.

Related Stress

A portable, unprepared simple reaction time (USRT) test is described. This test is particularly suitable for assessing performance in the field as a function of arousal-related stress. The test, which is housed in a small, battery-powered cassette recorder, presents a visual stimulus at quasi-random intertrial intervals ranging from 1 to 10 s. The subject responds by pressing a button as quickly as possible, whereupon the reaction time is displayed. The duration of the test is limited only by the cassette tape on which the data are recorded, but 10 min is recommended. Reviewed are studies illustrating the test's brief practice curve and its sensitivity to arousal-related stress.

Simple Rt

In this study simple reaction time (simple RT) to a visual stimulus of a single subject was measured during spontaneous and controlled breathing, in which the duration of expiration was prolonged (Asian technique). The phases of breathing were classified as the pause between expiration and inspiration, the inspiration phase, the transition from inspiration to expiration, and the expiration phase. Analysis of data from about 6000 trials indicated that RT to the stimulus was shortest during the transition from inspiration to expiration in controlled breathing.

The Right

To determine whether reaction time varies as a function of tone frequency and/or ear stimulated 27 adult subjects were presented with two two-tone series (1,000 Hz vs 2,500 Hz and 1,500 Hz vs 4,000 Hz) in a simple reaction-time paradigm. The analyses clearly indicated that the higher tone in each series and stimulation to the right ear resulted in significantly shorter reaction times. These results were interpreted as indicating that cerebral asymmetries are apparent in tasks and with stimuli that do not seem to require higher-order inferences regarding the functional organization of the cerebral hemispheres.
