Brief report: "I can't talk about it:" sexuality and self-silencing as interactive predictors of depressive symptoms in adolescent dating couples.

This longitudinal study examined sexual intercourse within adolescent romantic relationships as a couple-level moderator of the association between adolescent individual characteristics and depressive symptoms. Two hundred nine middle- and older-adolescent dating couples (aged 14-17 and 17-21, respectively) reported on their own self-silencing, depressive symptoms, and sexual behaviors. At Time 1, frequency of sexual intercourse significantly moderated the relationship between self-silencing and depressive symptoms, such that adolescents higher in self-silencing engaging in more frequent sex were at risk for clinically significant levels of depression. Adolescents who were low in self-silencing were not at increased risk for depression, regardless of frequency of sex. Self-silencing also significantly predicted increases in depressive symptoms from Time 1 to Time 2. Implications include the possibility that frequent sex in highly self-silencing adolescents exacerbates psychological depletion believed to link self-silencing to depressive symptoms, and that this depletion compounds over time.

The communicative functions of touch in humans, nonhuman primates, and rats: a review and synthesis of the empirical research.

Although touch is one of the most neglected modalities of communication, several lines of research bear on the important communicative functions served by the modality. The authors highlighted the importance of touch by reviewing and synthesizing the literatures pertaining to the communicative functions served by touch among humans, nonhuman primates, and rats. In humans, the authors focused on the role that touch plays in emotional communication, attachment, bonding, compliance, power, intimacy, hedonics, and liking. In nonhuman primates, the authors examined the relations among touch and status, stress, reconciliation, sexual relations, and attachment. In rats, the authors focused on the role that touch plays in emotion, learning and memory, novelty seeking, stress, and attachment. The authors also highlighted the potential phylogenetic and ontogenetic continuities and discussed suggestions for future research.
