Two experiments investigated the oppositeness between simple geometric figures, with children and adult participants. Various transformations of a figure were studied, obtained by transforming one or more qualities into their opposite properties. In Experiment I participants were asked to produce an opposite figure and in Experiment 2 to recognize the most opposite of a figure in figure pair presentation. Results showed that axis transformations generated obvious oppositeness in figures with a salient axis orientation. In Experiment I, children also tended to favor Size and Surface transformation, while adults favored Shape transformation (equilateral-to-elongated and angular-to-round). These transformations, however, tumed out to be less popular in the recognition task (Experiment 2). A general non-additive effect of combined transformations on the perception of oppositeness was found. Various anisotropies in the direction (e.g.: from small to large and viceversa) were identified in both production and recognition tasks.

Abstract
Two experiments investigated the oppositeness between simple geometric figures, with children and adult participants. Various transformations of a figure were studied, obtained by transforming one or more qualities into their opposite properties. In Experiment I participants were asked to produce an opposite figure and in Experiment 2 to recognize the most opposite of a figure in figure pair presentation. Results showed that axis transformations generated obvious oppositeness in figures with a salient axis orientation. In Experiment I, children also tended to favor Size and Surface transformation, while adults favored Shape transformation (equilateral-to-elongated and angular-to-round). These transformations, however, tumed out to be less popular in the recognition task (Experiment 2). A general non-additive effect of combined transformations on the perception of oppositeness was found. Various anisotropies in the direction (e.g.: from small to large and viceversa) were identified in both production and recognition tasks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
