Communion and agency are fundamental dimensions of social perception and judgment. Previous research revealed a primacy of communion in social information processing. The present research investigates whether there is a similar asymmetry in the "density" of communion and agency. We test whether communal content is more densely clustered in memory than agentic content, that is, more similar to other communal content than agentic content is similar to other agentic content. Three multidimensional scaling studies address this question and suggest an interaction with valence: While negative communal content is more densely clustered than negative agentic content, we find no differences in density between positive communal and positive agentic content. In addition to enhancing our understanding of the fundamental dimensions and their structural representation, this research might open a new perspective on old questions regarding person perception and implicit personality theories.
