Consummatory suppression due to incentive downshift is not a consequence of enhanced search behavior
(Elsevier Science, 2013-06)
Rats shifted from 32% to 4% sucrose solution consume less from the 4% solution than rats that experience only the 4% solution. This consummatory suppression, a phenomenon known as consummatory successive negative contrast ...
Open field exposure facilitates consummatory extinction
(Lippincott Williams, 2016-12)
During extinction the organism learns that a conditioned stimulus or a conditioned response is no longer associated with an unconditioned stimulus, and as a consequence a decrement in the response is presented. The exposure ...
Successive negative contrast after partial reinforcement in the consummatory behavior of rats
(Elsevier Inc, 2004-12)
Rats given access to a 32% sucrose solution later reject a 4% solution significantly more than controls that have only received the 4% solution. In Experiment 1, this consummatory successive negative contrast (cSNC) effect ...
Ethanol facilitates consummatory extinction
(Elsevier Science, 2009-11)
Rats given access to an empty sipper tube after having obtained 32% sucrose in the same situation undergo extinction of consummatory behavior (cE). Ethanol (0.75 and 1 g/kg, i.p.) accelerated cE when administered before ...
Ontogeny of consummatory successive negative contrast in rats
(John Wiley & Sons Inc, 2014-07)
Consummatory successive negative contrast (cSNC) occurs whenorganisms repeatedly exposed to a high-magnitude reward are suddenly given alow-magnitude reward. This results in a significant reduction in the consumption ofthe ...
Effects of pretraining treatment with testosterone on successive and anticipatory negative contrast
(Pergamon-Elsevier Science Ltd, 2012-02)
Previous research indicated that the suppression of consummatory behavior that follows incentive downshift in male rats is attenuated by testosterone (T) administration during training. The present experiments were designed ...
IMITATION IN PIGEONS (COLUMBA LIVIA): THE ROLE OF THE CONSUMMATORY RESPONSE
(Sociedad Mexicana de Análisis de la Conducta / Mexican Society of Behavior Analysis, 2015)
Complex effects of reward upshift on consummatory behavior
(Elsevier Science, 2016-08)
Exposing rats to an upshift from a small reward to a larger reward sometimes yields evidence of consummatory successive positive contrast (cSPC), an effect that could be a suitable animal model of positive emotion. However, ...
Posttrial corticosterone administration enhances the effects of incentive downshift: Exploring the boundaries of this effect
(American Psychological Association, 2009-12)
Posttrial administration of corticosterone was previously shown to enhance consummatory successive negative contrast (cSNC) in rats. The present series of experiments provides additional information that helps determine ...
Two profiles in the recovery of reward devaluation in rats: Latent class growth analysis
(Elsevier Ireland, 2018-09)
Consummatory successive negative contrast (cSNC) occurs when animals exposed to an unexpected downshift from a high palatable reward (e.g., 32% sucrose solution) to a less preferred one (e.g., 4% sucrose solution) show an ...
