Caffeine and visuo-spatial attention

Kenemans, J. Leon, Verbaten, Marinus N.·1998·Psychopharmacology

Abstract

The effects of two doses of caffeine (1.5 and 3 mg/kg) on various aspects of visual selective attention were investigated in 24 healthy human subjects. Specific task conditions were compared to provide measures of selectivity for a location in the visual field, of distractibility, of selectivity among response alternatives, and of strategic influences. In two out of three tasks, caffeine speeded responses significantly. However, these effects did not differ across conditions within-task, so there was no indication that they were to due to (a) specific effect(s) on one or more of the attentional sub-functions. The results suggest that the beneficial effects of caffeine in low-load conditions cannot be attributed to reduced distractibility or increased suppression of task-irrelevant response tendencies.

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.
