Medium Group

Responses on the Activation–Deactivation Adjective Check List were recorded for forty–eight subjects who were performing a visual perceptual information processing task at one of three levels of task difficulty. In general, significant task performance differences in the expected direction were recorded. Two of the activation measures were found to differentiate between low and high task difficulty groups, while the scores for the medium group fell between these two-but did not significantly differ from either. Gender differences for both performance and activation measures were largely not significant.

Hemispheric Specialisation

The notion that visual laterality patterns may be attributable to attentional allocation rather than hemispheric specialisation was examined in three experiments. In Experiment I, high verbal ability subjects were found to be less lateralised on a letter name match task than low verbals. In Experiment II, stimulus probability was shown to affect laterality patterns for name but not for physical matches. Again, low verbals were affected more than highs. Experiment III produced results identical to those of Experiment II although, in the latter experiment, visual fields were defined vertically rather than horizontally from the midline. Together, these results support the following generalisations: (1) visual asymmetries have their locus in a post-perceptual information processing stage; (2) visual asymmetries may be altered by manipulating stimulus probability; (3) verbal ability differences in laterality may not reflect neuroanatomical differences but merely cognitive capacity and (4) it may be unnecessary to invoke differential hemispheric specialisation in order to account for visual lateral asymmetries.

Selection Of

We attempt to resolve some details of Barsalou's theory. (1) The mechanism that guides selection of perceptual information may be the efferent control of activity. (2) Information about a world that is not accessible to the senses can be constructed in the process of semiotic mediation. (3) Introspection may not be a kind of perception; rather, semiotically mediated information processing might be necessary for the emergence of introspection.

Theoretical Issues

Current work on perceptual information processing in children is frequently interpreted as showing that child/adult performance differences in perceptual tasks are caused, not by structural factors, but by the absence, in younger subjects, of appropriate encoding strategies, or by their inefficient use. The study of such strategies, which are believed to operate within broad parametric limits set by the basic perceptual processing stages, is of importance, particularly as it may be viewed as providing a conceptual framework for the study of individual and group differences in perceptual tasks. The author reviews methodological and theoretical issues which arise in connection with the developmental study of perceptual strategies, and concludes the field would benefit from greater conceptual and methodological rigour.
