Özet:
The central issue to which this thesis addresses itself essentially concerns the vexed question of how visual form perception (and perception in general) may most adequately be explained. Generally speaking, theorists who have concerned themselves primarily with the explanation of form perception in infrahumans have adopted a basically reductonativistic approach to this problem., Thus theories advanced to explain shape and pattern perception in 'simpler' species (such as the rat) have typically been in the nature of neurophysiologically-based models which place emphasis upon the role of innate perceptual mechanisms in the processing and encoding of stimulus information, (eg Dodwell 1964, 1970a). Recently, however, the validity of this theoretical approach has been seriously challenged by McGonigle and Jones (1975, 1977). In particular, these theorists criticise such models on the grounds that they attempt to explain perception with reference only to how individual stimuli are processed and consequently take no account of the role of context in the determination of perceived stimulus structure. For their own part, McGonigle and Jones argue that any (individual) stimulus may generally be structured in a variety of different ways and therefore cannot in itself have any absolute perceptual meaning. Rather, these theorists believe, it is only when a stimulus is judged by a perceiver with respect to some criterion or other that (a particular) structure may be perceived. Thus, according to this view, the perceived properties of any stimulus are in fact determined by the context within which it is embedded, since it is the properties of the stimuli with which it is compared that are held to specify the criteria by which the single stimulus may be judged. The purpose of the current investigation was to evaluate further the relative merits of the conflicting theoretical approaches outlined above. Consistent with that aim, two series of experiments were performed which sought to examine the role of context in the perception of shape similarity by rats and humans.
