Rate Deceleration

In two experiments, factors known to affect speed of simple reaction time (RT) were varied, and the phasic heart-rate deceleration preceding the reaction signal was measured. Both heart-rate deceleration and RT were affected by incentive, preparatory interval, and mode of presentation (whether predictable or unpredictable) of the preparatory intervals in a series. But the effect of a factor on one could not predict its effect upon the other, and heart-rate deceleration and RT were generally uncorrelated.

Two different reaction-time conditions were employed to explore differences in “mental set” between 2 groups of children: one with anamnestic and/or electroencephalographic evidence of cerebral dysfunction (the “brain-damaged” group); the other, a control group of normal children. There were 15 boys in each group. The groups were matched for age and IQ. The procedure consisted of regular and irregular preparatory interval conditions. The results demonstrated that latency was directly related to length of preparatory interval for the normals but not for brain-damaged Ss. No clear separation between normal and brain-damaged Ss was obtained when the set-index formula was employed. However, when ages 8 through 10 were analyzed separately, a good separation could be obtained.

Response Stimulus

Aggrandized fluctuations in the series of reaction times (RTs) are a very sensitive marker of neurocognitive disorders present in neuropsychiatric populations, pathological ageing and in patients with acquired brain injury. Even though it was documented that processing inconsistency founds a background of higher-order cognitive functions disturbances, there is a vast heterogeneity regarding types of task used to compute RT-related variability, which impedes determining the relationship between elementary and more complex cognitive processes. Considering the above, our goal was to develop a relatively new assessment method based on a simple reaction time paradigm, conducive to eliciting a controlled range of intra-individual variability. It was hypothesized that performance variability might be induced by manipulation of response-stimulus interval’s length and regularity. In order to verify this hypothesis, a group of 107 healthy students was tested using a series of digitalized tasks and their results were analyzed using parametric and ex-Gaussian statistics of RTs distributional markers. In general, these analyses proved that intra-individual variability might be evoked by a given type of response-stimulus interval manipulation even when it is applied to the simple reaction time task. Collected outcomes were discussed with reference to neuroscientific concepts of attentional resources and functional neural networks.
