RESUMEN
OBJECTIVE: Open objects encourage interactivity and closed objects discourage it. Repeated experiences with open and closed objects are thought to give rise to spatial concepts that can be used to represent a variety of entities such as societies, others, and the self. The present investigation pursues the idea that preferring that which is open to that which is closed is more compatible with an agreeable mode of interacting with others. METHOD: Three studies (total N = 901) asked participants whether they preferred "open" or "closed" as spatial concepts. Such preferences were linked to variations in agreeableness, peer perceptions, and daily measures of pro-social functioning. RESULTS: Open-preferring, relative to closed-preferring, individuals scored higher in agreeableness (Study 1) and were rated by peers as interpersonally warmer (Study 2). Open preferences varied within and across persons in a daily diary protocol and, in both cases, higher levels of open preference were linked to higher levels of pro-social feeling (Study 3). CONCLUSION: The findings point to a fundamental component of spatial orientation that plays a significant role in encouraging (open) or discouraging (closed) warm, interactive relations with others.
