Preference for 50% reinforcement over 75% reinforcement by pigeons
Nov 01, 2009; ... When pigeons are given a choice between an initial-link alternative that results in either a terminal-link stimulus correlated with 100% reinforcement or a stimulus correlated with 0% reinforcement (overall 50% reinforcement) and another initial-link alternative that always results in a ...
Animal memory: The contribution of generalization decrement to delayed conditional discrimination retention functions
Nov 01, 2009; ... Delayed conditional discriminations in which a sample indicates which comparison stimulus is correct have typically been used in working memory research with animals. Following acquisition with no (0-sec) delay between the offset of the sample and the onset of the comparison stimuli, delays of ...
A learned flavor preference persists despite the extinction of conditioned hedonic reactions to the cue flavors
Nov 01, 2009; ... Learned flavor preferences can be strikingly persistent in the face of behavioral extinction. Harris, Shand, Carroll, and Westbrook (2004) suggested that this persistence may be due to flavor preference conditioning's producing a long-lasting change in the hedonic response to the conditioned ...
Effects of pretraining on acquisition of novel configural discriminations in human predictive learning
Nov 01, 2009; ... In two experiments, participants acquired one of two target configural discriminations (a biconditional or negative patterning discrimination) in a predictive learning task. In Experiment 1, participants were pretrained with either a configural or an elemental discrimination; in Experiment 2, ...
Learning-related shifts in generalization gradients for complex sounds
Nov 01, 2009; ... Learning to discriminate stimuli can alter how one distinguishes related stimuli. For instance, training an individual to differentiate between two stimuli along a single dimension can alter how that individual generalizes learned responses. In this study, we examined the persistence of shifts ...
