Time Movement

The motor performance of 32 college men was measured on the following tests: arm strength, arm reaction and movement times, arm-and-leg serial reaction and movement times. Specificity of variance of individual differences was found for single, simple, and discrete limb movements and for three programmed series of large RT-MT movements which involved 240 responses.

Very High

The RT of 50 college men was measured under normal (N) and artificial (E) limb mass conditions. It was hypothesized that RT in condition E would be significantly faster than in N because the heavier mass would encourage a stronger conscious and willful intent, during the response foreperiod, to trigger the simple learned RT response stored in the memory motor drum. The results ( t = 4.202, p < .05) substantiated this hypothesis. Even though the relationship of RTs in N and E conditions was moderately large ( r = .56), the specificity was very high, 69%; thus the possibility that two separate neuromotor programs are involved cannot be excluded. It is concluded that in a simple RT experiment the creation of a situation during the response foreperiod which increases S's conscious and willful intent to respond, will result in a faster RT. Also, the results support the known specificity of individual differences in performance of simple discrete motor acts.

Are Individual Differences in Absentmindedness Correlated with Individual Differences in Attention?

Cognitive Failures Questionnaire

We administered the Cognitive Failures Questionnaire (CFQ) and one of two versions of the Attention Network Test (ANT) to 200 participants. Orthogonal subtraction scores based on performance (reaction time and error rate) from selected conditions of the ANT provided measures of the efficacy of three attention components: alerting, orienting, and executive control, while the total CFQ score provided a global measure of absentmindedness. Executive control was not associated with the CFQ in either experiment. When alertness was generated by a warning tone, greater alerting effects in reaction time were associated with higher CFQ scores (greater absentmindedness). The orienting effects in accuracy obtained from the two versions of the ANT varied with absentmindedness in opposite directions, suggesting that these two tests tap different aspects of orienting.
