“…The R e variable thus reflects the tightness or looseness of each schema cluster. Within a schema cluster, the degree to which a particular instance adheres to its prototype (i.e., the cluster centroid) is reflected by the measure Proportion of Schematic Steps (POSS) developed by Bersted, Brown, & Evans (1968). The POSS statistic varies from zero to unity; a zero POSS value would refer to a histoform that constituted a random sequence of column heights, whereas unity would refer to the actual most probable sequence of column heights designated as the prototype.…”

This experiment was conducted to determine the extent to which Ss encode relevant stimulus attributes and abstract conceptual rules in a pattern-recognition task involving complex multidimensional histoforms which are deviants of three different population prototypes. Task-memory requirements were varied in a multiple-alternative discrimination task by presenting stimuli either simultaneously or sequentially for comparison. Results showed that Ss learned the relevant dimensions along which the stimuli varied to the extent that they could only recognize histoforms as having approximately the same magnitudes of deviation from the prototypes. Performance was higher, however, under the simultaneous condition, suggesting that Ss failed to combine learned attributes into conceptual rules to a degree sufficient for a reduction in information processing and storage requirements to occur.
