Vicarious learning and the development of fears in childhood

Vicarious learning has long been assumed to be an indirect pathway to fear; however, there is only retrospective evidence that children acquire fears in this way. In two experiments, children (aged 7-9 years) were exposed to pictures of novel animals paired with pictures of either scared, happy or no facial expressions to see the impact on their fear cognitions and avoidance behavior about the animals. In Experiment 1, directly (self-report) and indirectly measured (affective priming) fear attitudes towards the animals changed congruent with the facial expressions with which these were paired. The indirectly measured fear beliefs persisted up to 3 months. Experiment 2 showed that children took significantly longer to approach a box they believed to contain an animal they had previously seen paired with scared faces. These results support theories of fear acquisition that suppose that vicarious learning affects cognitive and behavioral fear emotion, and suggest possibilities for interventions to weaken fear acquired in this way.     

When ambiguity hurts: social standards moderate self-appraisals in generalized social phobia

Thirty-nine individuals with generalized social phobia (social anxiety disorder) and 39 nonclinical controls performed a public speech after receiving cues about social standards. Using a novel video manipulation paradigm, one third of participants received cues indicating that standards for performance were high, one third received cues that standards were low, and the remaining third were given no explicit information about expected standards (i.e., standards were ambiguous). Individuals with social phobia performed objectively worse than controls in all conditions, but rated their performance as being worse only in the high and ambiguous standards conditions. These results suggest that in social phobia, negative self-perception is context-dependent. Implications for the cognitive model and treatment are discussed.     

Conflict in the kitchen: Contextual modulation of responsiveness to affordances

Recently, human behavior has been considered the product of continuous interactions between perception, cognition and action in which “affordances” (action possibilities the environment has to offer) play an important role. Converging evidence suggests that multiple action possibilities simultaneously compete for further processing, while external and internal factors (e.g., incoming sensory information, predictions) bias this competition. In the present study we used a stop-task to investigate whether context is able to modulate the strength of the responsiveness to affordances. We therefore placed participants in an actual kitchen and workshop during electroencephalographic recordings. A faster response to context congruent objects demonstrated that the direct surrounding is able to affect responsiveness to affordances. In addition, when responses needed to be withheld, context congruent objects evoked greater response conflict as indicated by an enhanced N2 Event Related Potential (ERP) component.     

Effects of an 8-week meditation program on the implicit and explicit attitudes toward religious/spiritual self-representations

Explicit self-representations often conflict with implicit and intuitive self-representations, with such discrepancies being seen as a source of psychological tension. Most of previous research on the psychological effects of mindfulness-meditation has assessed people’s self-attitudes at an explicit level, leaving unknown whether mindfulness-meditation promotes changes on implicit self-representations. Here, we assessed the changes in implicit and explicit self-related religious/spiritual (RS) representations in healthy participants following an 8-week mindfulness-oriented meditation (MOM) program. Before and after meditation, participants were administered implicit (implicit association test) and explicit (self-reported questionnaires) RS measures. Relative to control condition, MOM led to increases of implicit RS in individuals whit low pre-existing implicit RS and to more widespread increases in explicit RS. On the assumption that MOM practice may enhance the clarity of one’s transcendental thoughts and feelings, we argued that MOM allows people to transform their intuitive feelings of implicit RS as well as their explicit RS attitudes.     

3D feedback and observation for motor learning: Application to the roundoff movement in gymnastics

In this paper, we assessed the efficacy of different types of visual information for improving the execution of the roundoff movement in gymnastics. Specifically, two types of 3D feedback were compared to a 3D visualization only displaying the movement of the expert (observation) as well as to a more ‘traditional’ video observation. The improvement in movement execution was measured using different methods, namely subjective evaluations performed by official judges, and more ’quantitative appraisals based on time series analyses. Video demonstration providing information about the expert and 3D feedback (i.e., using 3D representation of the movement in monoscopic vision) combining information about the movement of the expert and the movement of the learner were the two types of feedback giving rise to the best improvement of movement execution, as subjectively evaluated by judges. Much less conclusive results were obtained when assessing movement execution using quantification methods based on time series analysis. Correlation analyses showed that the subjective evaluation performed by the judges can hardly be predicted/ explained by the ‘more objective’ results of time series analyses.

The General Factor of Personality and general intelligence: Testing hypotheses from Differential-K,Life History Theory,and strategic differentiation–integration effort

Life history as applied to human psychology has progressed on different levels of analysis including between racial groups (Differential-K) and between individuals (Life History Theory). While the approaches at each level have garnered significant research support, some findings at the level of individual differences are inconsistent with findings from the level of group differences. The association between the General Factor of Personality and general intelligence was examined across and within racial groups to investigate the inconsistency. The results were in line with predictions derived from strategic differentiation–integration effort (SD–IE), the proposition that aggregation amongst variables decreases as life history strategy slows. The results suggest SD–IE may be a useful tool in reconciling the apparent contradictions across the levels of analysis.     

Additive and synergistic relations of early mother–child and caregiver–child interactions and socioeconomic outcomes in adulthood

Prior theoretical and empirical studies have linked the first 3 years of children's life with later life outcomes. One primary explanation is the critical role these experiences play in children's early brain development (including their early language and cognitive abilities) and subsequent schooling achievement. The current study is a registered report with two complementary research objectives: (1) examine to what extent stimulating and responsive interactions with mothers and nonparental caregivers during the first 3 years of life show additive or synergistic associations with key socioeconomic outcomes in adulthood (i.e., educational attainment, salary, and employment status), and (2) examine to what extent academic skills (i.e., mathematics, vocabulary, and literacy) during childhood and adolescence mediate these associations. The sample included 1364 individuals from a birth cohort study who were followed until age 26. Mother–child interactions had positive associations with educational attainment and negative associations with full-time employment, though no synergistic associations were found for the socioeconomic outcomes. In addition, the indirect effects of mother–child interactions on educational attainment through mathematics were strongest for children with less stimulating and responsive caregiver–child interactions. Potential implications of these findings for developmental theory are discussed.
