HIERARCHIES IN CONCEPT ATTAINMEN IN SELECTION MODE WITH EXEMPLAR AND NON-EXEMPLAR START CARDS

The purpose of this study was to investigate the generality of the hierarchy of concepts to the selection mode with exemplar or nonexemplar start cards. The logical hierarchy of concepts in which lower level concepts form the components of higher level concepts was found to operate empirically in the context of the selection mode with a complete learning task. Furthermore, the Type of Start Card was found not to affect the relative difficulty of the levels of the hierarchy. Also noted was a faster time-per-trial for females over males and a Type Concept by Type Start Card interaction on per cent correct card choices. © 1969, Psychonomic Journals, Inc..
