No masking between test and mask components in perceptually different depth planes

2-D cues to perceived depth organization have been used to segregate test and mask stimulus components in a discrimination task. Observers made either spatial-frequency or orientation judgments on a rectangular test component by itself or in the presence of constant rectangular masks. There were two basic masking conditions: same-plane or different-plane. In the same-plane conditions, the test components and masks are perceived as existing in the same depth plane. In the different-plane conditions, the test and mask components are perceived to exist in different depth planes. The perception of different depth planes was achieved by using perceived occlusion, which could place either component closer or further from the observer. The results suggest that when test and mask components are separated into different depth planes they no longer influence one another. This effect could be observed in either depth organization, test components in front of the masks or mask components in front of the test. These results indicate that the figure-ground organization of components is not important. Only the designation as existing in the same or different depth planes affects whether or not a mask is effective.     

Are Men and Women Really That Different? Examining Some of Sexual Strategies Theory (SST)��s Key Assumptions about Sex-Distinct Mating Mechanisms

Sexual Strategies Theory (SST; Buss and Schmitt 1993) suggests that, typically, men more so than women are more likely to spend proportionately more of their mating effort in short-term mating, lower their standards in short-term compared to long-term mating, feel reproductively constrained, and seek, but certainly not avoid, sex if pregnancy is likely in short-term relationships. A series of 4 survey studies each containing hundreds of college student participants from the western portion of the United States were conducted to test these hypotheses. The findings are inconsistent with SST but are consistent with Attachment Fertility Theory (AFT; Miller et al. 2005) that argues for relatively few evolved gender differences in mating strategies and preferences.     

Suicide methods in singapore (2000-2004): types and associations

The choice of suicide methods varies between countries. Common methods used in Singapore between 2000 and 2004 were jumping (72.4%), hanging (16.6%), and poisoning (5.9%). Those who jumped were more likely to be young, single, female, and to have had a major mental illness. By comparison, those who hung themselves were more likely to be older (OR 2.68), Indian (OR 2.32), and to leave a suicide note (OR 1.53). Those who used poison were more likely to be married (OR 2.33), to be on antidepressants (OR 2.40), to have previously attempted suicide (OR 2.13), and to leave a letter (OR 2.30). The choice was determined by accessibility, acceptability, generational, gender, and racial factors.     

Remembering all that and then some: recollection of autobiographical memories after a 1-year delay

We have previously shown that repeated retrievals of remote autobiographical memories over the course of one month led to an overall increase in reported detail (Nadel, Campbell, & Ryan, 2007). The current study examined the retrieval of those same memories 1 year later in order to determine whether the level of detail remained stable or whether the memories returned to their original state. Participants reported even more details than they had recalled at least 1 year earlier, including new details that were reported for the first time. This finding was consistent across both multiple and single retrieval conditions, suggesting that the critical factor leading to the increase in recall was the passage of time. These findings provide evidence for long-term effects of repeated retrieval on memory content.     

Passive coping response to depressive symptoms among low-income homebound older adults: Does it affect depression severity and treatment outcome?

Due to their homebound state, lack of financial resources, and/or other life demands, a significant proportion of depressed, low-income homebound older adults experience depression. Because of their limited access to psychotherapy, most of these older adults self-manage their depressive symptoms. The purposes of this study were to examine (1) the relationship between homebound older adults' coping responses to depressed mood and the severity of their depressive symptoms at baseline (n = 121), and (2) the moderating effect of passive coping responses on the relationship between participation in problem-solving therapy (PST: in-person or telehealth delivery) and depressive symptoms at 12- and 24-week follow-ups. Controlling for the effects of demographic and disability characteristics, cognitive passive coping was significantly associated with baseline depressive symptoms, while behavioral passive coping was not. The main effect of baseline cognitive passive coping response was also significant in mixed-effects regression analysis, but the interaction between coping pattern and group was not significant. The results point to a possibility that cognitive passive copers may have benefited as much from PST as the rest of the PST participants. Further research needs to examine the moderating effect of coping responses to depressive symptoms on treatment efficacy of PST and other psychosocial interventions for late-life depression.     

Contributions of domain-general cognitive resources and different forms of arithmetic development to pre-algebraic knowledge

The purpose of this study was to investigate the contributions of domain-general cognitive resources and different forms of arithmetic development to individual differences in pre-algebraic knowledge. Children (n = 279, mean age = 7.59 years) were assessed on 7 domain-general cognitive resources as well as arithmetic calculations and word problems at start of 2nd grade and on calculations, word problems, and pre-algebraic knowledge at end of 3rd grade. Multilevel path analysis, controlling for instructional effects associated with the sequence of classrooms in which students were nested across Grades 2-3, indicated arithmetic calculations and word problems are foundational to pre-algebraic knowledge. Also, results revealed direct contributions of nonverbal reasoning and oral language to pre-algebraic knowledge, beyond indirect effects that are mediated via arithmetic calculations and word problems. By contrast, attentive behavior, phonological processing, and processing speed contributed to pre-algebraic knowledge only indirectly via arithmetic calculations and word problems.

Aggression by whom-aggression toward whom: Behavioral predictors of same- and other-gender aggression in early childhood

This study assessed girls' and boys' dominance-related behaviors (aggressive, commanding, submissive, and neutral behaviors) as they naturally occurred during interactions with male and female peers and evaluated the possibility that such behaviors elicit aggression from peers. Using a focal observational procedure, young girls' and boys' (N = 170; 54% boys) naturally occurring dominance-related behaviors and male and female peers' aggressive responses to those behaviors were recorded multiple times each week across the academic year. Findings suggested that same-gender aggression occurred at similar rates as other-gender aggression once tendencies toward gender-segregated play were controlled. Additionally, there were both gender-based similarities and differences in children's use of dominance-related behaviors in peer interactions and as antecedents for peers' aggression. The findings have implications for the literatures on aggression and gendered peer interactions. (PsycINFO Database Record (c) 2012 APA, all rights reserved).
