Environmental context effects in conceptual explicit and implicit memory

Previous research has found environmental context effects for both conceptual explicit and conceptual implicit memory (Parker, Gellatly, & Waterman, 1999). The research presented here challenges these findings on methodological grounds. Experiment 1 assessed the effects of context change on category-exemplar generation (conceptual implicit memory test) and category-cued recall (conceptual explicit memory test). Experiment 2 assessed the effects of context change on word association (conceptual implicit memory test) and word associate cued recall (conceptual explicit memory test). In both experiments, study-test changes in environmental context were found to influence performance only on tests of explicit memory. It is concluded that when retrieval cues across explicit and implicit tests are matched, and the probability of explicit contamination is reduced, then only conceptual explicit test performance is reduced by study-test changes in environmental context.     

Ready to make nice: parental socialization of young sons' and daughters' prosocial behaviors with peers

In this study, the authors examined the extent to which maternal and paternal parenting styles, cognitions, and behaviors were associated with young girls' and boys' more compassionate (prototypically feminine) and more agentic (prototypically masculine) prosocial behaviors with peers. Parents of 133 preschool-aged children reported on their authoritative parenting style, attributions for children's prosocial behavior, and responses to children's prosocial behavior. Approximately 6 months later, children's more feminine and more masculine prosocial behaviors were observed during interactions with unfamiliar peers and reported on by their preschool teachers. Boys and girls did not differ in the observed and teacher-reported measures of prosocial behavior. Compared to other parents, fathers of boys were less likely to express affection or respond directly to children's prosocial behavior. Mothers' authoritative style, internal attributions for prosocial behavior, and positive responses to prosocial behavior predicted girls' displays of more feminine prosocial actions and boys' displays of more masculine prosocial actions toward peers. Relations were similar but weaker for fathers' parenting, and after accounting for mother' scores, fathers' scores accounted for unique variance in only one analysis: Teachers reported more masculine prosocial behavior in boys of fathers who discussed prosocial behavior. Overall, the results support a model of parental socialization of sex-typed prosocial behavior and indicate that mothers contribute more strongly than do fathers to both daughters' and sons' prosocial development.     

Individual differences in adult decision-making competence

The authors evaluated the reliability and validity of a set of 7 behavioral decision-making tasks, measuring different aspects of the decision-making process. The tasks were administered to individuals from diverse populations. Participants showed relatively consistent performance within and across the 7 tasks, which were then aggregated into an Adult Decision-Making Competence (A-DMC) index that showed good reliability. The validity of the 7 tasks and of overall A-DMC emerges in significant relationships with measures of socioeconomic status, cognitive ability, and decision-making styles. Participants who performed better on the A-DMC were less likely to report negative life events indicative of poor decision making, as measured by the Decision Outcomes Inventory. Significant predictive validity remains when controlling for demographic measures, measures of cognitive ability, and constructive decision-making styles. Thus, A-DMC appears to be a distinct construct relevant to adults' real-world decisions.     

Reexamining the factor structure of the 20-item Toronto alexithymia scale: commentary on Gignac, Palmer, and Stough

Gignac, Palmer, and Stough (2007/this issue) test a number of different latent factor models for the TAS-20 using a community sample of 355 participants and conclude that this scale is best represented by a "nested factors model," with five substantive factors and a method factor. Gignac et al. also report that the correlated three-factor model and a comparable higher order model supported by most studies produced poor levels of incremental close fit. In this article, we challenge Gignac et al.'s unheralded and largely unsupported use of nested model fitting and the uncritical acceptance of exceptionally high cutoff levels to assess goodness of fit (GOF). Using more traditional and empirically supported model testing procedures and a more flexible approach to the interpretation of multiple tests of GOF, we interpret Gignac et al.'s results as actually supportive of the traditional three-factor model and one that has been recovered in 17 of the 24 factor analytic studies of the TAS-20.     

Capacity estimates in working memory: Reliability and interrelationships among tasks

The concept of capacity has become increasingly important in discussions of working memory (WM), in so far as most models of WM conceptualize it as a limited-capacity mechanism for maintaining information in an active state, and as capacity estimates from at least one type of WM task—complex span—are valid predictors of real-world cognitive performance. However, the term capacity is also often used in the context of a distinct set of WM tasks, change detection, and may or may not refer to the same cognitive capability. We here develop maximum-likelihood models of capacity from each of these tasks—as well as from a third WM task that places heavy demands on cognitive control, the self-ordered WM task (SOT)—and show that the capacity estimates from change detection and complex span tasks are not correlated with each other, although capacity estimates from change detection tasks do correlate with those from the SOT. Furthermore, exploratory factor analysis confirmed that performance on the SOT and change detection load on the same factor, with performance on our complex span task loading on its own factor. These findings suggest that at least two distinct cognitive capabilities underlie the concept of WM capacity as it applies to each of these three tasks.     

Sequential dynamics in visual short-term memory

Visual short-term memory (VSTM) is thought to help bridge across changes in visual input, and yet many studies of VSTM employ static displays. Here we investigate how VSTM copes with sequential input. In particular, we characterize the temporal dynamics of several different components of VSTM performance, including: storage probability, precision, variability in precision, guessing, and swapping. We used a variant of the continuous-report VSTM task developed for static displays, quantifying the contribution of each component with statistical likelihood estimation, as a function of serial position and set size. In Experiments 1 and 2, storage probability did not vary by serial position for small set sizes, but showed a small primacy effect and a robust recency effect for larger set sizes; precision did not vary by serial position or set size. In Experiment 3, the recency effect was shown to reflect an increased likelihood of swapping out items from earlier serial positions and swapping in later items, rather than an increased rate of guessing for earlier items. Indeed, a model that incorporated responding to non-targets provided a better fit to these data than alternative models that did not allow for swapping or that tried to account for variable precision. These findings suggest that VSTM is updated in a first-in-first-out manner, and they bring VSTM research into closer alignment with classical working memory research that focuses on sequential behavior and interference effects.     

Singularity in Beauvoir's The Ethics of Ambiguity

Though it has gone unnoticed so far in Beauvoir Studies, the term “singularity” is a technical one for Simone de Beauvoir. In the first half of the essay I discuss two reasons why this term has been obscured. First, as is well known Beauvoir has not been read in the context of the history of philosophy until recently. Second, in The Ethics of Ambiguity at least, singularité is translated both inconsistently and quite misleadingly. In the second half of the essay I attempt to demonstrate the importance of this term in The Ethics. The will to disclose being is the will to disclose the singularity of the other, whether human, land, sky or painting. Ambiguity, which Beauvoir distinguishes from absurdity in Camus, is an image suggesting this necessarily mutual disclosure of singularity.     

Trait Resilience Fosters Adaptive Coping When Control Opportunities are High: Implications for the Motivating Potential of Active Work

Purpose

We examine the interaction between trait resilience and control in predicting coping and performance. Drawing on a person–environment fit perspective, we hypothesized resilient individuals would cope and perform better in demanding work situations when control was high. In contrast, those low in resilience would cope and perform better when control was low. Recognizing the relationship between trait resilience and performance also could be indirect, adaptive coping was examined as a mediating mechanism through which high control enables resilient individuals to demonstrate better performance.

Methodology

In Study 1 (N = 78) and Study 2 (N = 94), participants completed a demanding inbox task in which trait resilience was measured and high and low control was manipulated. Study 3 involved surveying 368 employees on their trait resilience, control, and demand at work (at Time 1), and coping and performance 1 month later at Time 2.

Findings

For more resilient individuals, high control facilitated problem-focused coping (Study 1, 2, and 3), which was indirectly associated with higher subjective performance (Study 1), mastery (Study 2), adaptive, and proficient performance (Study 3). For more resilient individuals, high control also facilitated positive reappraisal (Study 2 and 3), which was indirectly associated with higher adaptive and proficient performance (Study 3).

Implications

Individuals higher in resilience benefit from high control because it enables adaptive coping.

Originality/value

This research makes two contributions: (1) an experimental investigation into the interaction of trait resilience and control, and (2) investigation of coping as the mechanism explaining better performance.
