Reward has been shown to change behavior as a result of incentive learning (by motivating the individual to increase their effort) and instrumental learning (by increasing the frequency of a particular behavior). However, Palminteri et al. (2011) demonstrated that reward can also improve the incidental learning of a motor skill even when…

The association of specific events with the context in which they occur is a fundamental feature of episodic memory. However, the underlying network mechanisms generating what-where associations are poorly understood. Recently we reported that some hippocampal principal neurons develop representations of specific events occurring in particular…

The nucleus accumbens (NAc) plays a role in hedonic reactivity to taste stimuli. Learning can alter the hedonic valence of a given stimulus, and it remains unclear how the NAc encodes this shift. The present study examined whether the population response of NAc neurons to a taste stimulus is plastic using a conditioned taste aversion (CTA)…

TWO EXPERIMENTS WERE CONDUCTED TO CLASSIFY AND TO CONDITION REWARD RESPONSIVENESS IN KINDERGARTEN CHILDREN. IN THE FIRST EXPERIMENT, 207 CHILDREN WITH A MEDIAN AGE OF 6.0 WERE CLASSIFIED ACCORDING TO THEIR RESPONSIVENESS TO A HIERARCHY OF REWARDS. AFTER TWO SESSIONS INVOLVING TWO-CHOICE INSTRUMENTAL CONDITIONING TASKS, 60 PERCENT OF THE CHILDREN…

The effect of cognitive style and learning conditions on the rote verbal learning performance of Mexican American subjects classified as field independent or field dependent was investigated. Field dependent referred to a strong perceptual influence caused by the context or background while field independent referred to an ability to overcome the…
