STUDIES ON BEHAVIOR. I. DIFFERENTIAL SENSITIVITY TO PENTOBARBITAL OF PECKING PERFORMANCE IN PIGEONS DEPENDING ON THE SCHEDULE OF REWARD

DEWS, PETER B.·1955·The Journal of Pharmacology and Experimental Therapeutics

Abstract

Pigeons working in a Skinner box developed different rates of pecking depending on the schedule of reward. When every 50th peck was rewarded (FR5O) the rate of response was high and constant. When the first peck after an interval of fifteen minutes was rewarded (15'FI) the average rate of pecking was low and there was a steady increase in rate through the interval. Pecking of the birds on 15'FI was markedly reduced by doses of pentobarbital which had no effect, or caused an increase in rate of pecking of the same birds working on FR5O. This differential sensitivity to depression by pentobarbital of performance on different schedules shows that by use of these techniques a behavioral effect of a drug can be detected and measured under circumstances when the drug does not affect the physical ability of the pigeon to execute a peck.

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.
