    • Latent inhibition (LI) is a phenomenon observed when repeated, non-reinforced presentation of a stimulus results in a retardation of subsequent conditioning to that stimulus. Several recent experiments have suggested that LI is abolished in conditioned suppression paradigms following acute, low doses of amphetamine given during pre-exposure and conditioning. Experiment 1 sought to increase the generality of this finding in an appetitive LI paradigm, using a dose of amphetamine previously shown to disrupt the LI effect in an aversive paradigm (Killcross and Robbins 1993)...

    • Latent inhibition (LI) is a phenomenon in which repeated, non-reinforced presentation of a stimulus retards subsequent conditioning to that stimulus. Several recent experiments have suggested that LI is abolished following acute, low doses of amphetamine given during pre-exposure and conditioning, and this effect has been attributed to amphetamine-induced changes in dopamine levels in the nucleus accumbens...

    • Latent inhibition (LI) is a cognitive process whereby repeated exposure of a stimulus without consequence impedes the formation of subsequent associations with that stimulus. A number of studies in the rat have reported that LI is impaired by moderate systemic doses of amphetamine, an effect believed to be mediated via dopamine (DA) release in the nucleus accumbens...

    • Latent inhibition (LI) is a measure of reduced learning about a stimulus to which there has been prior exposure without any consequence. It therefore requires a comparison between a pre-exposed (PE) and a non-pre-exposed (NPE) condition. Since, in animals, LI is disrupted by amphetamines and enhanced by antipsychotics, LI disruption has been proposed as a measure of the characteristic attentional deficit in schizophrenia: the inability to ignore irrelevant stimuli...
