Changes in Heart Rate and Slow Brain Potentials Related to Motor Preparation and Stimulus Anticipation in a Time Estimation Task

A time-estimation task was considered for inclusion in the Performance Evaluation Tests for Environmental Research (PETER) battery. As part of this consideration, the effects of repeated testing on the reliability of time judgments were studied. The method of production was used to estimate eight time intervals. Five trials per day at each interval were administered individually to each of 19 subjects for 15 consecutive workdays. Two scores, constant error and variable error, were reported. The effect of days was not significant for constant error and was moderate for variable error ( p < .04). The standard deviations were relatively stable across trials. A pronounced decline in reliability over repeated days of testing was found for both errors. It was concluded that this time-estimation test would be a poor candidate for inclusion in PETER, but further research is warranted because of the potential unique contribution of a time-estimation task in a performance test battery.

The Devil

Individuals differ in the extent to which they respond negatively to uncertainty. Although some individuals feel little discomfort when facing the unknown, those high in neuroticism find it aversive. We examined neurophysiological responses to uncertainty using an event-related potential framework. Participants completed a time-estimation task while their neural activity was recorded via electroencephalography. The feedbackrelated negativity (FRN), an evoked potential that peaks approximately 250 ms after the receipt of feedback information, was examined under conditions of positive, negative, and uncertain feedback. The magnitude of these responses was then analyzed in relation to individual differences in neuroticism. As expected, a larger FRN was observed after negative feedback than after positive feedback for all participants. For individuals who scored highly on trait neuroticism, however, uncertain feedback produced a larger neural response than did negative feedback. These results are discussed in terms of affective responses to uncertainty among neurotic individuals.

Repeated Test

A time estimation task was considered for inclusion in the Performance Evaluation Tests for Environmental Research (PETER) battery. As part of this consideration the effects of repeated testing on the reliability of time judgments, using the method of production, was studied. Forty trials per day were administered individually to each of 19 subjects for 15 consecutive weekdays. Descriptive statistics are reported and the need for knowledge about the reliability coefficient over repeated test administrations in the context of performance testing in exotic environments is discussed.
