Attachment in donor‐conceived adults: Curiosity,search, and contact

Donor‐conceived (DC) people represent a unique population with atypical family structures. This study examined whether individual differences in attachment predict adults' self‐reported curiosity about their donor conception identity, as well as attempts to find the donor and establish contact. Data were collected from 488 DC people from the Donor Sibling Registry (DSR). People who were high in attachment‐related anxiety were more curious than others about their donor conception. Despite this curiosity, however, highly anxious people were more disengaged from donor conception and were not more likely than others to search for or have made contact with their donor. These findings suggest that insecure attachment—particularly attachment anxiety—may contribute to people's willingness to incorporate donor conception into their identities.

Electroencephalographic evidence for improved visual working memory performance during standing and exercise

While a substantial body of research has investigated the effects of aerobic exercise on cognitive performance, few have monitored exercise‐concurrent cognitive processes via electroencephalography and fewer still using an event‐related potential (ERP) approach. As such, little is known regarding how the temporal dynamics of cognitive processing are influenced during aerobic activity. Here, we aimed to elucidate the influence of aerobic exercise on the temporal dynamics of concurrent visual working memory (VWM) performance. Participants performed a VWM retro‐cue task at rest and during aerobic exercise across two postural modalities: seated (using a stationary bicycle) and standing upright (using a treadmill). Three consecutive phases of the VWM processing pipeline were assessed by means of lateralized ERPs: access of VWM representations, response selection, and response execution. Aerobic exercise and upright posture were found to have significant effects on VWM performance, facilitating processing speed in the retro‐cue task. This facilitation arose primarily at an intermediary stage between the phases of accessing VWM representations and response selection. Our findings hold implications not only for understanding the influence of aerobic activity on VWM, but also for contemporary models of VWM that are built exclusively on data recorded during stationary, seated conditions.     

Radical embodied cognitive science and problems of intentionality

Radical embodied cognitive science (REC) tries to understand as much cognition as it can without positing contentful mental entities. Thus, in one prominent formulation, REC claims that content is involved neither in visual perception nor in any more elementary form of cognition. Arguments for REC tend to rely heavily on considerations of ontological parsimony, with authors frequently pointing to the difficulty of explaining content in naturalistically acceptable terms. However, many classic concerns about the difficulty of naturalizing content likewise threaten the credentials of intentionality, which even advocates of REC take to be a fundamental feature of cognition. In particular, concerns about the explanatory role of content and about indeterminacy can be run on accounts of intentionality as well. Issues about explanation can be avoided, intriguingly if uncomfortably, by dramatically reconceptualizing or even renouncing the idea that intentionality can explain. As for indeterminacy, Daniel Hutto and Erik Myin point the way toward a response, appropriating an idea from Ruth Millikan. I take it a step further, arguing that attention to the ways that beliefs’ effects on behavior are modulated by background beliefs can help illuminate the facts that underlie their intentionality and content.

     

Longitudinal effects of human supremacy beliefs and vegetarianism threat on moral exclusion (vs. inclusion) of animals

Stronger beliefs in human supremacy over animals, and stronger perceived threat posed by vegetarianism to traditional practices, are associated with stronger speciesism and more meat consumption. Both variables might also be implicated in the moral exclusion of animals. We tested this potential in a 16-month longitudinal study in the USA (N = 219). Human supremacy showed longitudinal effects on the moral exclusion of all animals. Vegetarianism threat only predicted moral exclusion of food animals (e.g., cows and pigs), and, unexpectedly, appealing wild animals (e.g., chimps and dolphins). These findings demonstrate the importance of both human supremacy and perceived threat in explaining moral exclusion of animals and highlight potential paradoxical negative consequences of the rise of vegetarianism.     

Narcissism and Sensitivity to Criticism: A Preliminary Investigation

Two studies investigated the connection between narcissism and sensitivity to criticism. In study 1, participants completed the Narcissistic Personality Inventory (NPI) and the Sensitivity to Criticism Scale (SCS) and were asked to construct and deliver speeches to be rated by performance judges. They were then asked whether they would like to receive evaluative feedback. Narcissism and sensitivity to criticism were mildly, but not significantly, negatively correlated and had contrasting relationships with choices regarding feedback. Highly narcissistic participants tended to seek (rather than avoid) feedback, whereas highly sensitive participants tended to reject feedback opportunities. Study 2 examined the relationship between sensitivity to criticism and both overt and covert narcissism. Those scoring high on the trait narcissism, as measured by the NPI, tended to be less sensitive to criticism, sought (rather than avoided) feedback opportunities, experienced little internalized negative emotions in response to “extreme” feedback conditions, and did not expect to ruminate over their performance. By contrast, participants scoring high on a measure of “covert narcissism” were high in sensitivity to criticism, tended to avoid feedback opportunities, experienced high levels of internalized negative emotions, and showed high levels of expected rumination. These findings suggest that the relationship between narcissism and sensitivity to criticism is highly dependent upon the definition or “form” of narcissism considered.     

Young adult international adoptees' search for birth parents

This study examines international adoptees and factors associated with searching for birth parents. A total of 1,417 international adoptees in The Netherlands, aged 24 to 30 years, were divided into 4 groups: uninterested nonsearchers, interested nonsearchers, searchers, and reunited searchers. In total, 32% of adoptees had searched. Although the majority of searchers were well-adjusted, they had more problems--mainly internalizing problems--than uninterested nonsearchers. These problems, however, were not caused by the search itself. It is concluded that searching is the product of natural curiosity influenced by external factors such as the divorce of adoptive parents and the options for searching.     

Perfectionism, and Cognitions, Affect, Self-esteem, and Physiological Reactions in a Performance Situation

The current paper describes the results of an experiment in which 200 students who varied in levels of trait perfectionism performed a laboratory task and then were assessed in terms of levels of state affect, state self-esteem, and state automatic thoughts. Independent variables included task difficulty (high versus moderate level of difficulty) and performance feedback independent of their actual level of performance (positive or negative). Analyses also examined objective levels of performance (i.e., the number of errors on the task) and initial confidence in performance. Analyses showed that the experience of state automatic thoughts involving perfectionism was associated with negative automatic thoughts, negative affective reactions, and lower state self-esteem. Analyses of changes in mood and self-esteem showed generally that participants high in socially prescribed perfectionism had increased levels of dysphoria and anxiety and lower levels of state self-esteem following the experience of negative performance feedback or after having a relatively poor performance. Analyses of the physiological measures found increased systolic blood pressure among self-oriented perfectionists who had poorer performance and among socially prescribed perfectionists who had received negative feedback about their performance. The results for heart-rate changes yielded a less clear pattern, though there was evidence that participants with high socially prescribed perfectionism had increased heart rate if they received negative feedback and were relatively low in confidence. Collectively, these findings illustrate that how perfectionists react in challenging situations varies as a function of actual performance, performance feedback, and feelings of personal efficacy.

Violated wishes about division of childcare labor predict early coparenting process during stressful and nonstressful family evaluations

Prior research has indicated that expectant parents overestimate the extent to which fathers will take part in the “work” of parenting, with mothers often becoming disenchanted when these expectations are violated following the baby's arrival. In this study, we examine the role of violated wishes concerning childcare involvement in accounting for variability in maternal and paternal marital satisfaction, and in early coparenting behavior as assessed during family‐interaction sessions. The results indicate possible negative effects of violated wishes on the enacted family process and confirm previous findings regarding the effects of marital satisfaction. In addition, we uncovered differences in the way that violated maternal wishes are related to coparenting during playful and mildly stressful family interactions.
