Scaling relative incentive value: Different adjustments to incentive downshift in pigeons and rats
(Elsevier Science, 2008-11)
Previous research suggests that pigeons and rats show differences in their behavioral adjustments in spaced-trial, incentive-downshift situations. Also, Papini and Pellegrini [Papini, M.R., Pellegrini, S., 2006. Scaling ...
Propranolol reverses open field effects on frustration
(Elsevier, 2014-12)
Reactivity to a reward is affected by prior experience with different reinforcer values of that reward, a phenomenon known as incentive relativity. Incentive relativity can be studied via the consummatory successive negative ...
Long-lasting effects of perinatal asphyxia on exploration, memory and incentive downshift
(2011)
Perinatal asphyxia remains as one of the most important causes of death and disability in children, without an effective treatment. Moreover, little is known about the long-lasting behavioral consequences of asphyxia at ...
Scaling relative incentive value in consummatory behavior
(Academic Press, 2006-11)
Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments ...
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 ...
Effects of testosterone administration and gonadectomy on incentive downshift and open field activity in rats
(Pergamon-Elsevier Science Ltd, 2012-07)
Previous research showed that the effects of incentive downshift in male rats are attenuated by a pretrial opportunity to ejaculate. Because ejaculation raises testosterone (T) levels and has anxiolytic-like effects in ...
Scaling relative incentive value in anticipatory behavior
(Academic Press, 2007-05)
Papini and Pellegrini (Papini, M. R., & Pellegrini, S. Scaling relative incentive value in consummatory behavior. Learning and Motivation, in press) observed that, within limits, the level of consummatory responding of ...
Early experience and incentive relativity in adulthood
(International Society of Comparative Psychology, 2014-09)
Human and animal studies have shown the long-lasting impact of early life experience on the development of individual differences in stress responsiveness in later life. Despite the numerous works that evaluate the effect ...
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 ...
