Feeling-of-warmth judgments in category learning with pictorial stimuli

The aim of the study was to investigate feeling- of-warmth judgments (or participants’ judgments about how close they are to the acquisition of categorization rule) during the process of learning rulebased categories with pictorial stimuli. Each stimulus consisted of three positions which represented a dimension in which either of two thematically related drawings of objects (candle–light bulb, violin–trumpet, and bolt–nut) could appear as values. Tasks varied on three levels of categorization diculty based on conjunctive, conjunctive-disjunctive or complex rule. Seventy psychology students participated in the study. Di erences in classification accuracy and feeling-of-warmth judgments with respect to three levels of task diculty, four learning stages and two performance groups (good and poor learners) were analyzed. The results showed that classification accuracy linearly increased through four learning stages for subjects who have successfully mastered the conjunctive and complex task, while classification accuracy in conjunctive-disjunctive task increased starting from the second learning stage. Similarly, feeling-of-warmth judgments linearly increased through four learning stages for subjects who have successfully mastered the complex task, while in conjunctive and conjunctivedisjunctive tasks, judgments increased starting from the second learning stage. Classification accuracy and feeling-of-warmth judgments for poor learners remained low through the whole learning process.
