Interaction of raclopride and preparatory interval effects on simple reaction time performance

MacDonald, Christopher J., Meck, Warren H.·2006·Behavioural Brain Research

Abstract

In a series of three experiments, simple reaction time (RT) was characterized with respect to a variable preparatory interval (PI) in order to investigate the relationship between interval timing and RT. In Experiment 1, it was shown that RT decreases as a function of PI and that this effect varies with amount of training. In Experiment 2, RT was shown to increase during probe trials that used a novel 6.25s PI, suggesting that the specific durations of the PIs encoded during initial training contribute to the PI effect on RT. In Experiment 3, 100 microg/kg i.p. of raclopride proportionally slowed RT as a function of the PI. These results are discussed within the context of neuropsychological models of interval timing and support an underlying role for cortico-striatal dopaminergic function in temporal processing and simple RT measurements.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
