Visual prominence and representationalism

A common objection to representationalism is that a representationalist view of phenomenal character cannot accommodate the effects that shifts in covert attention have on visual phenomenology: covert attention can make items more visually prominent than they would otherwise be without altering the content of visual experience. Recent empirical work on attention casts doubt on previous attempts to advance this type of objection to representationalism and it also points the way to an alternative development of the objection.     

Recollections of parent–child relationships,attachment insecurity,and obsessive–compulsive beliefs

To adequately understand Obsessive Compulsive Disorder (OCD), it is important to understand the developmental origins of obsessive beliefs and corresponding compulsive acts. Prior work has shown that having cold, neglectful parents in childhood and/or insecure attachment styles are both linked to emotional disturbances. In this study, we explored the potential contributions of early parent–child relationships to attachment styles and the severity of obsessive–compulsive beliefs in adulthood. A sample of 397 college students completed online, self-report measures of retrospective parent–child relationships, adult attachment styles, and ongoing obsessive–compulsive symptoms. Analyses revealed that attachment anxiety partially mediated the association between parent–child relationships and obsessive beliefs; attachment avoidance failed to operate as a mediating mechanism. Our findings provide support for interpersonal approaches to obsessive–compulsive symptoms and disorder, with implications for the continuity of relationship dysfunction from childhood into adulthood.     

Experimental activation of anti-cuckoldry mechanisms responsive to female sexual infidelity

Recent research indicates that men may have evolved mechanisms dedicated to detecting and responding to the risk of partner infidelity. Because activation of these “anti-cuckoldry” mechanisms depends on partner infidelity, or the perception of partner infidelity, existing evidence for such mechanisms relies on correlational data. The current study tests several predictions regarding men’s anti-cuckoldry mechanisms in an experimental design. As predicted, the results demonstrated: (1a) experimental activation of men’s anti-cuckoldry mechanisms by presenting them with a vignette depicting a female partner’s sexual infidelity; (1b) no activation of men’s anti-cuckoldry mechanisms by presenting them with a vignette depicting a sexual encounter without female infidelity; (2) experimental activation of men’s anti-cuckoldry mechanisms was influenced by their perceived risk of partner infidelity; and (3) women were not influenced by the partner infidelity manipulation.     

Ten years of career success in relation to individual and situational variables from the employee development literature

Individual, situational, and socio-demographic variables from the employee development literature were combined with theory and research on career success in a ten-year study of 289 workers from across many jobs and industries in the workforce. Support for employee development by one's employer ten years prior and a trend of increasing/accumulating support contributed to career success, providing the first long-term confirmation of the value to careers from support for development by employers. Proactive personality had unique effects on success not accounted for by a broad array of other variables, strengthening conclusions from prior research about the predictive value of proactive personality which were based on data not controlling for these variables. Finally, achievement goal orientation influenced success in a unique way via “profile effects:” Goal orientation dimensions interacted to predict success, suggesting simple linear effects (e.g. being more learning-oriented) may be inadequate in explaining career success. Implications for future research and practice are discussed.     

Understanding suicide terrorism: Premature dismissal of the religious-belief hypothesis

We comment on work by Ginges, Hansen, and Norenzayan (2009), in which they compare two hypotheses for predicting individual support for suicide terrorism: the religious-belief hypothesis and the coalitional-commitment hypothesis. Although we appreciate the evidence provided in support of the coalitional-commitment hypothesis, we argue that their method of testing the religious-belief hypothesis is conceptually flawed, thus calling into question their conclusion that the religious-belief hypothesis has been disconfirmed. In addition to critiquing the methodology implemented by Ginges et al., we provide suggestions on how the religious-belief hypothesis may be properly tested. It is possible that the premature and unwarranted conclusions reached by Ginges et al. may deter researchers from examining the effect of specific religious beliefs on support for terrorism, and we hope that our comments can mitigate this possibility.     

Surprise-induced blindness: a stimulus-driven attentional limit to conscious perception

The cost of attending to a visual event can be the failure to consciously detect other events. This processing limitation is well illustrated by the attentional blink paradigm, in which searching for and attending to a target presented in a rapid serial visual presentation stream of distractors can impair one's ability to detect a second target presented soon thereafter. The attentional blink critically depends on 'top-down' attentional settings, for it does not occur if participants are asked to ignore the first target. Here we show that 'bottom-up' attention can also lead to a profound but ephemeral deficit in conscious perception: Presentation of a novel, unexpected, and task-irrelevant stimulus virtually abolishes conscious detection of a target presented within half a second after the 'Surprise' stimulus, but only for its earliest occurrences (generally 1 to 2 presentations). This powerful but short-lived deficit contrasts with a milder but more enduring form of attentional capture that accompanies singleton presentations in rapid serial visual presentations. We conclude that the capture of stimulus-driven attention alone can limit explicit perception.     

Using Principal Components as Auxiliary Variables in Missing Data Estimation

To deal with missing data that arise due to participant nonresponse or attrition, methodologists have recommended an “inclusive” strategy where a large set of auxiliary variables are used to inform the missing data process. In practice, the set of possible auxiliary variables is often too large. We propose using principal components analysis (PCA) to reduce the number of possible auxiliary variables to a manageable number. A series of Monte Carlo simulations compared the performance of the inclusive strategy with eight auxiliary variables (inclusive approach) to the PCA strategy using just one principal component derived from the eight original variables (PCA approach). We examined the influence of four independent variables: magnitude of correlations, rate of missing data, missing data mechanism, and sample size on parameter bias, root mean squared error, and confidence interval coverage. Results indicate that the PCA approach results in unbiased parameter estimates and potentially more accuracy than the inclusive approach. We conclude that using the PCA strategy to reduce the number of auxiliary variables is an effective and practical way to reap the benefits of the inclusive strategy in the presence of many possible auxiliary variables.
