Beyond perceptual symbols: A call for representational pluralism

Recent evidence from cognitive neuroscience suggests that certain cognitive processes employ perceptual representations. Inspired by this evidence, a few researchers have proposed that cognition is inherently perceptual. They have developed an innovative theoretical approach that rests on the notion of perceptual simulation and marshaled several general arguments supporting the centrality of perceptual representations to concepts. In this article, I identify a number of weaknesses in these arguments and defend a multiple semantic code approach that posits both perceptual and non-perceptual representations.     

Relationship Commitment and Perceptions of Harm to Self

Commitment to a relationship is associated with a number of consequences, including willingness to sacrifice for the relationship, greater cognitive interdependence between partners, and increased trust in one's partner. Consistent with such consequences, we hypothesized that greater commitment is associated with decreased perceptions of one's partner as a source of harm to the self. We conducted two studies (one correlational, one experimental) to test hypotheses regarding the association between commitment level and personal harm perceptions, based on tenets from interdependence theory and balance theory. Study 1 revealed significant negative associations between commitment and personal harm perceptions. Results from Study 2 suggest that greater commitment leads to decreased perceptions of partner-based risk and increased risky behavioral tendencies.
