| Abstract: | Emotional facial expressions are perceived categorically. Little is known about individual differences in the position of the category boundary, nor whether the category boundaries differ across stimulus continua. Similarly, little is known about whether individuals’ category boundaries are stable over time. We investigated these topics in a series of experiments designed to locate category boundaries using converging evidence from identification and discrimination tasks. We compared both across individuals and within individuals across two sessions that spanned a week. Results show differences between individuals in the location of category boundaries, and suggest that these differences are stable over time. We also found differences in boundary location when we compared images depicting different models. |
