Book Description
Using methodology devised by Pearce, Esber, George and Haselgrove (2008), the role of attention in discrimination learning in pigeons was investigated. In Chapter 1 a review of literature revealed several unanswered questions Experiments 1 and 2 explored whether attention is paid to entire dimensions or to individual stimuli. In a test, pigeons learnt a discrimination based upon previously relevant stimuli more rapidly than they did a discrimination based on previously irrelevant stimuli. This was evident when discriminations were based on colours that were close or far apart on the spectrum. Experiment 3 attempted to detect latent inhibition in pigeons. No effect was observed; findings were attributed to the amount of attention paid to a stimulus being determined by the degree of responding to it. In Experiment 4 compounds in which components were superimposed on the other eliminated the effects seen in Experiment 3. Experiment 5 explored whether more attention is paid to reliable or unreliable predictors of outcome. No evidence was found of greater attention paid to partially-reinforced stimuli. Experiment 6 found pigeons learnt more rapidly about previously reinforced stimuli when accompanied by stimuli with low associative strength than with stimuli with high associative strength. Experiment 7 explored whether attention increased to previously non-reinforced stimuli from a discrimination. No evidence was found. Experiment 8 asked the same question but paired previously non-reinforced and previously irrelevant stimuli during Stage 2. The discrimination based upon non-reinforced stimuli was learnt more rapidly than the discrimination based upon irrelevant stimuli. From the findings presented it seems attentional changes were masked by the amount of time a pigeon spent pecking at a stimulus. The exception was the final experiment. It seems attentional changes as envisaged by Mackintosh (1975a) may occur, but are only apparent when the effect of the amount of pecking is reduced.

Book Description
From the Foreword: "Is it possible at present to identify a core cluster of theoretical ideas, concepts, and methods with which everyone working in the area of learning and cognition needs to be familiar? Would it be possible to make explicit the relationships that we feel do or must exist among the various subspecialties, ranging from conditioning through perceptual learning and memory to psycholinguistics, and to present these in a sufficiently organized way to help specialists and non-specialists alike in relating particular lines of research to the broader spectrum of activity? These questions were posed to a substantial number of investigators who are currently most active in developing the ideas and doing the research. Their response constitutes this Handbook..." First published in 1975, Volume 1 of this Handbook attempts to present an overview of the field and to introduce the principal theoretical and methodological issues that will persistently recur in the expanded treatments of specific research areas that comprise the later volumes. Deferring to the current Zeitgeist rather than to chronology, they begin with the present state of cognitive psychology, then introduce the comparative approach, and conclude this volume with a rapid, three-chapter review of the evolution of ideas from conditioning to information processing.
