Representing social categories based on shared cultural knowledge in adults

The study investigated whether adults rely on the cues of shared cultural knowledge when forming social category representations. We used a modified version of the memory confusion paradigm, where participants are presented with the photographs of people differing along social category distinctions while listening to utterances associated with the pictures. In the test phase, the task is to match the utterances to the photographs. When category representations are formed, more within-category errors than between-category errors are expected. Experiment 1 contrasted two cues in social category representations: race and shared cultural knowledge. In Experiment 2, categorisation based on shared cultural knowledge was tested without any competing cue. Experiment 3 replicated previous results about automatic race encoding when no competing social distinction was available. Experiment 4 contrasted gender with cultural category membership. The results indicate that people encode information about race, gender, and cultural background; however, the latter two are more fundamental dimensions of social categorisation.
