Multidimensional psychophysics and selective attention in animals.

Notes that the hypothesis that animals selectively attend developed mainly in explanations of certain conditioning and discrimination learning phenomena. This hypothesis of selective attention is evaluated against a continuity (nonattentional) theory, and most, if not all, facts of simple learning can be accounted for by a nonattentional analysis. Thus, the usefulness of selective attention as an explanatory notion remains in doubt, and few phenomena can be regarded as exemplars of selective attention. In contrast, many examples of selective attention phenomena have been discovered in human information processing experiments. Emphasis in these experiments is on instructional and stimulus variables as they affect steady-state performance rather than response learning. Recent research with animals, modeled on human steady-state tasks, promises to provide similar instances of selective attention effects in performance.
