Boundary extension: the role of magnification, object size, context, and binocular information

Boundary extension is a tendency to remember close-up scenes as if they extended beyond the occluding boundaries. The authors explored the contributing factors using brief retention intervals and computer-generated images. Boundary extension turns out to be more complex than previously thought and is not linked to the effects of image magnification and field-of-view changes. Although this is consistent with the idea that boundary extension is the product of the activation of a mental schema that provides information of what is likely to exist outside the picture boundaries, the authors also found that properties of the object at the center of the picture can affect boundary extension independently of the information at the boundaries. In a test of boundary extension using stereograms, the effect does not seem to depend on amount of perceived depth, suggesting a weaker link to perception of space than previously hypothesized.     

Rejection sensitivity and the defensive motivational system: insights from the startle response to rejection cues

Rejection sensitivity (RS) is the disposition to anxiously expect, readily perceive, and intensely react to rejection. This study used the startle probe paradigm to test whether the affect-based defensive motivational system is automatically activated by rejection cues in people who are high in RS. Stimuli were representational paintings depicting rejection (by Hopper) and acceptance (by Renoir), as well as nonrepresentational paintings of either negative or positive valence (by Rothko and Miro, respectively). Eyeblink startle magnitude was potentiated in people high in RS when they viewed rejection themes, compared with when they viewed nonrepresentational negative themes. Startle magnitude was not attenuated during viewing of acceptance themes in comparison with nonrepresentational positive themes. Overall, the results provide evidence that for people high in RS, rejection cues automatically activate the defensive motivational system, but acceptance cues do not automatically activate the appetitive motivational system.     

The original MMPI and Colligan Norms revisited

Norms developed by Colligan, Osborne, Swenson, and Offord (1983) and others at the Mayo Clinic for the MMPI overcome criticisms that the MMPI is not useful in 2003 and representative. This study ascertained the classification of MMPI profiles of clinicians. Mayo Clinic norms are warranted in view of the similar classifications made using both methods based on the same MMPI data.     

Flirting and energetic arousal

76 college students were administered a self-reported energy scale and a flirtation inventory. Analysis indicated a significant relationship such that low scores on energy level were associated with low flirtation related activities, as well as low self-ratings on attractiveness and other variables.     

Moral principles as moral dispositions

What are moral principles? In particular, what are moral principles of the sort that (if they exist) ground moral obligations or—at the very least—particular moral truths? I argue that we can fruitfully conceive of such principles as real, irreducibly dispositional properties of individual persons (agents and patients) that are responsible for and thereby explain the moral properties of (e.g.) agents and actions. Such moral dispositions (or moral powers) are apt to be the metaphysical grounds of moral obligations and of particular truths about what is morally permissible, impermissible, etc. Moreover, they can do other things that moral principles are supposed to do: explain the phenomena “falling within their scope,” support counterfactuals, and ground moral necessities, “necessary connections” between obligating reasons and obligations. And they are apt to be the truthmakers for moral laws, or “lawlike” moral generalizations.     

Can survival processing enhance story memory? Testing the generalizability of the adaptive memory framework

Research from the adaptive memory framework shows that thinking about words in terms of their survival value in an incidental learning task enhances their free recall relative to other semantic encoding strategies and intentional learning (Nairne, Pandeirada, & Thompson, 2008). We found similar results. When participants used incidental survival encoding for a list of words (e.g., "Will this object enhance my survival if I were stranded in the grasslands of a foreign land?"), they produced better free recall on a surprise test than did participants who intentionally tried to remember those words (Experiment 1). We also found this survival processing advantage when the words were presented within the context of a survival or neutral story (Experiment 2). However, this advantage did not extent to memory for a story's factual content, regardless of whether the participants were tested by cued recall (Experiment 3) or free recall (Experiments 4-5). Listening to a story for understanding under intentional or incidental learning conditions was just as good as survival processing for remembering story content. The functionalist approach to thinking about memory as an evolutionary adaptation designed to solve reproductive fitness problems provides a different theoretical framework for research, but it is not yet clear if survival processing has general applicability or is effective only for processing discrete stimuli in terms of fitness-relevant scenarios from our past.     

Testing Models of Associations Between Depression and Parenting Self-efficacy in Mothers: A Meta-analytic Review

Numerous cross-sectional studies confirm the long-theorized association between mothers’ depression and lower parenting self-efficacy (PSE) beliefs. However, cross-sectional studies leave unanswered the direction of this association: Does depression predict PSE? Does PSE predict depression? Are both true? Does the strength of the association between depression and PSE, regardless of the direction, generalize across participant characteristics and study design features? How stable is PSE over time? And how effective are interventions at enhancing PSE? To answer these questions, we conducted a meta-analytic review of longitudinal studies. With 35 eligible studies (22,698 participants), we found support for both models: there was a significant pooled effect of both depression on PSE and of PSE on depression, with nearly identical effect sizes (d?=?????0.21 and ??0.22, respectively). The association was stronger in samples with mothers’ younger average age and studies that measured PSE among mothers relative to during pregnancy. We found a medium degree of stability in the index of PSE, d?=?0.60. Finally, the estimated pooled effect size between being in an intervention group versus control group and PSE was 0.505. Overall, we found support for (1) bidirectional associations between depression and PSE in mothers, (2) the stability of PSE over time, and (3) the strength of the relationship between PSE and depression with intervention. These results suggest the importance of continuing to develop, test, and disseminate interventions to enhance PSE. We interpret these findings in the context of both depression and low PSE having serious consequences for child outcomes and maladaptive parenting.
