Latent inhibition is a phenomenon by which exposure to an irrelevant stimulus impedes the acquisition or expression of conditioned associations with that stimulus. Latent inhibition, an integral part of the learning process, is observed in many species. This comprehensive collection of studies of latent inhibition, from a variety of disciplines including behavioural/cognitive psychology, neuroscience and genetics, focuses on abnormal latent inhibition effects in schizophrenic patients and schizotypal normals. Amongst other things, the book addresses questions such as, is latent inhibition an acquisition or performance deficit? What is the relationship of latent inhibition to habituation, extinction, and learned irrelevance? Does reduced latent inhibition predict creativity? What are the neural substrates, pharmacology, and genetics of latent inhibition? What do latent inhibition research and theories tell us about schizophrenia? This book provides a single point of reference for neuroscience researchers, graduate students, and professionals, such as psychologists and psychiatrists.

Latent inhibition is an exquisitely simple, robust, and pervasive behavioural phenomenon - the reduced ability of an organism to learn new associations to previously inconsequential stimuli. It has been demonstrated in a variety of animals, including humans, across many different learning tasks.

Latent Inhibition and Its Neural Substrates describes a neural network model of attentional processes during associative learning, mainly latent inhibition, and shows how variables in the model can be mapped onto different brain regions and neurotransmitters. The result is a neurophysiological model capable of generating predictions and descriptions of numerous experimental results using latent inhibition, including the effects of brain lesions, drug administration, and the combination of both. The model also explains the absence of latent inhibition in acute schizophrenia and its reinstatement by the administration of psychotropic drugs.

"Eight experiments tested priming in short-term memory as a model for latent inhibition and habituation. The model postulates that the two phenomena result from reduced processing when a representation of the target stimulus is already active (primed) in short-term memory at the time of its presentation. Priming is assumed to depend on the integrity of an association formed between the contextual stimuli and the conditional stimulus (CS) during exposure. Using a procedure that should have overshadowed the context, Experiment 1 found that latent inhibition and habituation were nevertheless maintained when a second CS of either equal or shorter duration overlapped with the target during exposure. Experiment 2 found no support for the priming of a configural stimulus when simultaneous compounds were preexposed. Experiment 3 ruled out sensitization and/or pseudoconditioning as an alternative explanation of latent inhibition. Experiments 4, 5 and 6 showed that sensory preconditioning as well as habituation and latent inhibition were obtained with compound exposure, providing evidence that the added CS was indeed processed along with the target. In Experiment 7, sequential pairings produced as much latent inhibition as compounds but less sensory preconditioning. Experiment 8 showed that retardation of conditioned inhibition was not attenuated by compound exposure. These results are interpreted as consistent with a correlational approach to classical conditioning." --
