Context and cognitions: environmental risk, social influence, and adolescent substance use

This study examined the cognitions thought to mediate the impact of context on adolescent substance use and also the extent to which context moderates the relations between these cognitions and use. Risk cognitions and behaviors were assessed in a panel of 746 African American adolescents (M age 10.5 at Wave 1, 12.2 at Wave 2). Results indicated that adolescents living in high-risk neighborhoods were more inclined toward substance use and more likely to be using at Wave 2. These context effects were mediated by the adolescents' risk cognitions: their risk images, willingness to use, and intentions to use. Also, context moderated the relation between willingness and use (the relation was stronger in high-risk neighborhoods) but it did not moderate the intentions to use relation.     

The longitudinal effects of alexithymia on romantic relationships

Using the tenets of Affection Exchange Theory, the study predicted longitudinal effects of alexithymia on both romantic relational outcomes (satisfaction and commitment) and relational communication (affectionate communication and relational maintenance behaviors). The study also predicted that Time 2 levels of relational communication would mediate the longitudinal effects of alexithymia on the relational outcomes. The results largely supported the predictions, with Time 1 alexithymia significantly negatively related to both relational outcome measures, affectionate communication, and two types of relational maintenance behaviors (understanding and assurances) at Time 2. Alternate models predicting alexithymia at Time 2 using the relational variables were nonsignificant. Finally, mediation was shown for both affectionate communication and understanding. Implications and possible directions for future research are explored.     

How personal standards perfectionism and evaluative concerns perfectionism affect the error positivity and post-error behavior with varying stimulus visibility

Error detection is required in order to correct or avoid imperfect behavior. Although error detection is beneficial for some people, for others it might be disturbing. We investigated Gaudreau and Thompson’s (Personality and Individual Differences, 48, 532?537, 2010) model, which combines personal standards perfectionism (PSP) and evaluative concerns perfectionism (ECP). In our electrophysiological study, 43 participants performed a combination of a modified Simon task, an error awareness paradigm, and a masking task with a variation of stimulus onset asynchrony (SOA; 33, 67, and 100 ms). Interestingly, relative to low-ECP participants, high-ECP participants showed a better post-error accuracy (despite a worse classification accuracy) in the high-visibility SOA 100 condition than in the two low-visibility conditions (SOA 33 and SOA 67). Regarding the electrophysiological results, first, we found a positive correlation between ECP and the amplitude of the error positivity (Pe) under conditions of low stimulus visibility. Second, under the condition of high stimulus visibility, we observed a higher Pe amplitude for high-ECP–low-PSP participants than for high-ECP–high-PSP participants. These findings are discussed within the framework of the error-processing avoidance hypothesis of perfectionism (Stahl, Acharki, Kresimon, Völler, & Gibbons, International Journal of Psychophysiology, 97, 153–162, 2015).     

Effects of appearance-based interventions on sun protection intentions and self-reported behaviors.

Two appearance-based interventions designed to increase sun protection intentions and behaviors were evaluated. Sixty-eight college students in Experiment 1 and 76 beachgoers in Experiment 2 were randomly assigned to receive or not receive a photoaging (premature wrinkling and age spots) information intervention and, separately, to receive or not receive a novel ultraviolet (UV) photo intervention that makes the negative-appearance consequences of UV exposure more salient. Both experiments indicated that the UV photo intervention significantly increased intentions to use sunscreen in the future. A follow-up conducted with the beach sample indicated that UV photo information also produced greater protective behaviors for incidental sun exposure and that the combination of UV photo and photoaging information resulted in substantially lower reported sunbathing.     

On the emotions that accompany autobiographical memories: Dysphoria disrupts the fading affect bias

Participants in two studies recalled autobiographical events and reported both the affect experienced at event occurrence and the affect associated with event recollection. The intensity of affect associated with a recalled event generally decreased, but the affective fading was greater for negative events than for positive events. The magnitude of this fading affect bias also varied with participants' dysphoria levels: Dysphorics showed a smaller fading affect bias than non-dysphorics. Additional analyses suggested that the fading affect bias is not a product of: (1) distorted retrospective memory for the affect originally accompanying events; (2) differences in the initial affect intensity of positive and negative events; or (3) differences in the ages of positive and negative events. Other variables that might be related to the fading affect bias are discussed.     

Smoking cessation: social comparison level predicts success for adult smokers.

The affiliation preferences of 151 adult heavy smokers who joined smoking cessation groups were assessed at the 1st group session and were then used to predict their smoking status 6 and 12 months later. Those who preferred to be in groups with other smokers who were having relatively little trouble quitting were more likely to be successful than were those who preferred others who were having more difficulty quitting. This prospective effect was mediated by psychological distancing from the image of the typical smoker: Preference for others who were doing well was associated with a decrease in perceived similarity to the typical smoker, which, in turn, was associated with successful cessation. Implications of these findings for cessation groups and social comparison theory are discussed.     

Using UV photography to reduce use of tanning booths: a test of cognitive mediation.

Two laboratory studies were conducted in which a new type of intervention was used to reduce ultraviolet radiation (UV) exposure from tanning booth use among college students (Time 1 Ns=70 and 134). The intervention uses UV photography to highlight the damage to facial skin caused by previous UV exposure. When the authors controlled for baseline measures of booth use, students in both studies who viewed their UV photographs reported less booth use at a follow-up session 3-4 weeks later than did students not shown a copy of their photograph. Also, in both studies, the decline in use was significantly mediated by a Tanning Cognition Index composed of variables suggested by the prototype-willingness (prototype) model of health risk: tanning attitudes, tanner prototypes, and willingness to engage in risky UV exposure.
