This study investigated the potential influences of a marital interaction involving affectionate touch and/or positive relationship-focused conversation on physiological reactivity to a subsequent laboratory stress task, and whether depressive symptoms moderated these relations. It was hypothesized that 1) the stress task would cause cardiac sympathetic activation and cardiac parasympathetic withdrawal; and that physical affection and/or positive conversation would 2) reduce sympathetic activation as indicated by cardiac interbeat interval (IBI), cardiac pre-ejection period (PEP), and finger pulse transit time (FPTT) and 3) reduce parasympathetic withdrawal (as indicated by respiratory sinus arrhythmia; RSA) in response to stress. Further, we expected that, compared to those lower in reported depressive symptoms, those higher in depressive symptoms 4) would show blunted cardiovascular activation in response to stress across experimental conditions; and after engaging in a positive marital exchange, 5) would demonstrate a smaller interaction-related reduction in stress-related sympathetic activation; but 6) show no difference in interaction-related reduction of stress-related parasympathetic withdrawal. Participants were 183 married couples who were at least moderately happy in their marriages and in generally good health. Participants completed a measure of depression (among other questionnaires) in an online survey, then attended a 3-hour laboratory session. After measuring baseline physiology with spouses in separate rooms, couples were then randomly assigned to either touch (while sitting quietly, then hug), talk (positive conversation, but no touch), both (touch while talking, then hug), or neither (sit quietly without touching or talking). Next, participants separately performed a stress-inducing speech task about their spouses’ strengths and weaknesses. Physiological indicators were recorded throughout the stress task. While positive conversation reduced husbands’ stress-related parasympathetic withdrawal, it predicted greater stress-related activation in wives’ PEP response. Stress reactivity (as indicated by FPTT) was reduced in husbands with lower depressive symptoms when the marital exchange included only touch or only talk, whereas for husbands with more depressive symptoms, there were no effects of the marital interaction. For wives, depressive symptoms predicted blunted cardiovascular activation regardless of positive interaction condition, as illustrated by smaller stress-related reduction in FPTT responses. Furthermore, higher self-reported depressive symptoms predicted larger interaction-related decreases in stress-related IBI responses in wives who experienced spousal touch. This study builds on previous work and is the first to explore how depressive symptoms may influence the relations between affectionate touch and stress reactivity.

This study investigated the potential influence of scent on women's mood and perceptions of men's attractiveness. Participants were 58 heterosexual female college students between the ages of 18-35 who were in decent health, did not smoke, and were not pregnant or nursing. They were asked to rate the physical attractiveness, datability, likability, sexual desirability, and perceived age of men in photographs. Photographs were taken from two online databases. During the ratings, the participants were exposed to either a pleasant scent with the putative human pheromone androstadienone or to the same pleasant scent without the pheromone (between subjects design). Analysis of covariance was used to compare effects of pheromone on ratings and pheromone on mood. Although there was a pheromone effect, it was not in the predicted direction. Participants gave higher ratings on datability when smelling the fragrance without the pheromone, suggesting the pheromone actually seemed to cause lower ratings of this quality. On the other hand, the scent with the pheromone may have reduced an increase in negative moods from pre- to post-task. Scent pleasantness was discovered to be an important predictor of both photo ratings and changes in mood during the photo rating session. Although the current study did not provide further evidence that androstadienone is associated with higher attractiveness ratings, it did support the idea that the pheromone may influence mood.
