Failure to Consider Future Consequences Increases the Effects of Alcohol on Aggression

The failure to consider the future consequences of one's behavior is a major risk factor for aggression. Aggressive people tend to act first, and think later. Some people focus on the -here and now rather than on the future, a tendency measured by the Consideration of Future Consequences (CFC) scale (Strathman, Gleicher, Boninger, & Edwards, 1994). Alcohol intoxication is a neuro-biological variable that produces similar effects. Participants in the present experiment completed the CFC scale and then consumed either an alcohol or a placebo beverage. Next, they competed against a same-sex ostensible partner on an interpersonally adversarial competitive task in which the winner could administer electric shocks to the loser (the aggression measure). As expected, aggression was highest in intoxicated persons with low CFC scores. Being unconcerned about the future consequences of one's actions, in conjunction with acute alcohol intoxication, combine in a pernicious manner to increase aggression.     

The powerful disregard social comparison information

Social comparisons are important because other people can serve as benchmarks to determine one's own capabilities and act as sources for inspiration. Despite this, people do not always fully utilize social comparison information. The present paper demonstrates that feelings of power may reduce use of social comparison information. In three experiments, participants were first induced to feel high or low in power, or were in a control condition. Then, they were exposed to either upward or downward comparison targets. In all three experiments, low power participants responded to targets with contrast or assimilation, whereas high power participants did not. This has important implications for our understanding of how people's positions in the social and organizational hierarchies affect their basic psychological functioning.     

When a new group identity does harm on the spot: Stereotype threat in newly created groups

The detrimental consequences of negative stereotypes on performance have been demonstrated in a variety of social groups with various stereotypes. The present studies investigate the minimal conditions for stereotype threat using newly created groups. Results of three experiments (total N = 184) demonstrate that in the negative stereotype condition, the more participants identified with their novel group, the stronger was their decrease in performance. In the control condition, identification was either not related to performance, or it had by trend a positive effect. The theoretical and practical implications of the findings are discussed with regard to stereotype threat and social identity theory. Copyright © 2011 John Wiley & Sons, Ltd.     

How to map the affective semantic space of scents

The investigation of the semantic space associated with subjective affective experiences or feelings linked to odour perception has recently emerged. Because of the specificity of the emotional effects of odours, the terms derived from traditional models of emotion are unlikely to optimally account for odour-associated feelings. In this study, sets of terms derived from two traditional models, basic emotions and valence by arousal by dominance dimensional emotions, were compared with a recently elaborated olfaction-specific set of terms (Geneva Emotion and Odour Scale; GEOS). Three main criteria were considered: (1) the feeling's intensity reported in response to odours; (2) the inter-rater agreement concerning the reported feelings; and (3) the power to discriminate feelings evoked by various odorous substances. The evidence strongly suggested that the set of terms proposed by GEOS outperformed the terms derived from the two classical models in measuring the subjective affective experience elicited by odours. These results are interpreted with respect to a good correspondence between the functions of olfaction and the meaning conveyed by GEOS terms.     

Watch this! Observed tool use affects perceived distance

Recent research has shown that being able to interact with an object causes it to be perceived as being closer than objects that cannot be interacted with. In the present study, we examined whether that compression of perceived space would be experienced by people who simply observed such interactions by others with no intention of performing the action themselves. Participants judged the distance to targets after observing an actor reach to an otherwise unreachable target with a tool (Experiment 1) or illuminate a distant target with a laser pointer (Experiment 2). Observing either type of interaction caused a compression of perceived space, revealing that a person’s perception of space can be altered through mere observation. These results indicate that shared representations between an actor and observer are engaged at the perceptual level easily and perhaps automatically, even in the absence of cooperation or an observer’s own intention to interact.     

Exploring replay value: shifts and continuities in user experiences between first and second exposure to an interactive story

While replay value is a common term in interactive entertainment, psychological research on its meaning in terms of user experiences is sparse. An exploratory experiment using the interactive drama "Fa?ade" was conducted (n=50) to examine shifts and continuities in entertainment-related user experiences between first and second exposure to the same system. A questionnaire with brief scales measuring various user-experience dimensions (interaction-related facets such as usability, flow, and presence, as well as narrative-related facets such as suspense and curiosity) was administered after the first and the second round of exposure. Findings suggest that replay produces gains in action-related experience components such as presence and effectance, whereas narrative-related experiences such as curiosity and suspense remain stable across exposures. Implications for theorizing on interactive entertainment experiences are discussed.     

Psychoanalysis and Nature: Commentary on Papers by Bodnar and Santostefano

This is a response to papers by Sebastiano Santostefano and Susan Bodnar. The response argues that the psychoanalytic view of constitutive conflict makes any assimilation of analysis and ecology very problematic. Patients may benefit from being in pleasant surroundings outside urban areas, but this is not psychoanalytic work. Psychoanalysis would entail them coming to understand why they are fueled by desires they do not recognize as their own. It would entail them working through how these desires have come to belong to them. Calling these desires natural or unnatural is not helpful, and it may be pernicious.     

Teachers’ epistemological beliefs as an antecedent of autonomy-supportive teaching

A large body of research has been devoted to the outcomes of autonomy-supportive teaching (AST). However, research on its antecedents is scarce. The present study explored teachers’ personal epistemology as a possible predictor of students’ perceptions of AST. We administered surveys to 622 students in 23 seventh- and eighth-grade classrooms regarding the extent to which their teachers tried to take the students’ perspective and to provide rationale—major aspects of autonomy support. At the same time, their teachers’ personal epistemologies were assessed. Hierarchical linear model analysis revealed that students of teachers scored with more objectivist (absolutist) personal epistemologies reported that their teachers were less likely to be autonomy supportive. AST, in turn, predicted students’ optimal internalization of pro-social behavior. Further exploration of a range of teachers’ personal characteristics, then, would appear to be an important and productive approach to understanding the variability of teachers’ engagement in autonomy supportive practices.     

Mother–infant interaction improves with a developmental intervention for mother–preterm infant dyads

While premature infants have a high need for positive interactions, both infants and their mothers are challenged by the infant‘s biological immaturity. This randomized clinical trial of 198 premature infants born at 29–34 weeks gestation and their mothers examined the impact of the H-HOPE (Hospital to Home: Optimizing the Infant's Environment) intervention on mother–premature infant interaction patterns at 6-weeks corrected age (CA). Mothers had at least 2 social environmental risk factors such as minority status or less than high school education. Mother–infant dyads were randomly assigned to the H-HOPE intervention group or an attention control group. H-HOPE is an integrated intervention that included (1) twice-daily infant stimulation using the ATVV (auditory, tactile, visual, and vestibular-rocking stimulation) and (2) four maternal participatory guidance sessions plus two telephone calls by a nurse-community advocate team. Mother–infant interaction was assessed at 6-weeks CA using the Nursing Child Assessment Satellite Training–Feeding Scale (NCAST, 76 items) and the Dyadic Mutuality Code (DMC, 6-item contingency scale during a 5-min play session). NCAST and DMC scores for the Control and H-HOPE groups were compared using t-tests, chi-square tests and multivariable analysis. Compared with the Control group (n = 76), the H-HOPE group (n = 66) had higher overall NCAST scores and higher maternal Social-Emotional Growth Fostering Subscale scores. The H-HOPE group also had significantly higher scores for the overall infant subscale and the Infant Clarity of Cues Subscale (p < 0.05). H-HOPE dyads were also more likely to have high responsiveness during play as measured by the DMC (67.6% versus 58.1% of controls). After adjustment for significant maternal and infant characteristics, H-HOPE dyads had marginally higher scores during feeding on overall mother–infant interaction (β = 2.03, p = 0.06) and significantly higher scores on the infant subscale (β = 0.75, p = 0.05) when compared to controls. In the adjusted analysis, H-HOPE dyads had increased odds of high versus low mutual responsiveness during play (OR = 2.37, 95% CI = 0.97, 5.80). Intervening with both mother and infant is a promising approach to help premature infants achieve the social interaction patterns essential for optimal development.
