While anger is a common problem for veterans returning from wars in Afghanistan and Iraq, veterans' understanding of the causes, course, and consequences of anger has not been explored. We conducted this qualitative study to learn veterans' perspectives about their anger problems. We identify and describe three distinct patterns of anger problems that emerged as a consequence of (a) loss of structure during reintegration to civilian life, (b) moral injury sustained through a wartime experience, and (c) posttraumatic stress disorder (PTSD). While anger problems tended to be short lived for those experiencing loss of structure, problems persisted for years for those with moral injury or PTSD. Anger following all three patterns negatively impacted veterans' experiences with reintegration. We discuss the implications of these findings.  相似文献

Perceived weight in the face and body size have been shown to be significant predictors of both attractiveness and health. Studies looking at the relationship between attractiveness, perceived health, and perceived weight in faces have found that individuals prefer a lower weight for attractiveness than for apparent health. Here, a group of twenty-four Asian participants were allowed to manipulate the apparent body mass indices (BMIs) of full-length photographs of young Malaysian Chinese women to enhance their perceived healthiness and attractiveness. Results showed that both men and women differentiated between attractiveness and health by preferring a lower BMI for attractiveness than health, suggesting a consistency in the preferred ideal BMI for attractiveness and healthy appearance across both sexes. Results also suggested that BMI provides important cues to judgments of attractive and healthy appearance.  相似文献

This study used a latent difference score growth model to investigate how changes in family structure (biological father and stepfather residence) and maternal employment are associated with American children's externalizing problem behaviours (EPB) from ages 4–10 and whether these associations vary by children's level of self-regulation. For all 4-year-old children, living with a biological father at age 4 was associated with reductions in EPB at ages 4–6 and later years, with no variation by child self-regulation. Living with a stepfather at age 4 was associated with higher levels of EPB at age 4; however, for less-regulated children, stepfather residence at ages 4 and 8 was associated with reductions in EPB between ages 4–6 and 8–10, respectively. Greater employment hours were associated with increased EPB in the next 2 years for less-regulated children of all ages; however, except for the age 4–6 transition, there was a lagged association that reduced behaviour problems after 2 years and outweighed short-term increases.  相似文献

This paper examines particular distortions in the process of free association characteristics of patients with narcissistic personality disorders. The author proposes that the dominant narcissistic transference developments typical of the early and middle phases of the analytic treatment of these patients are reflected in these distortions of free association. This paper gathers the various patterns that these defensive distortions present, along with technical interventions geared to deal with them.  相似文献

In line with every-day observation, research has established substantial individual differences in ethical behavior, especially dishonesty and cheating. However, these individual differences have remained mostly unexplained, especially in terms of traits as specified in models of basic personality structure. Theoretically, a prime candidate to account for these differences is the Honesty–Humility factor proposed as the sixth basic personality dimension within the HEXACO Model of Personality. Despite clear theoretical links, corresponding behavioral evidence is scarce and limited due to methodological caveats. In a series of six behavioral experiments we thus bridge the gap between behavioral ethics and personality research – critically testing whether individual differences in dishonest behavior can be accounted for by basic traits in general, and Honesty–Humility in particular. We implement different cheating paradigms, tasks, incentive structures, samples, and sets of covariates to evaluate the robustness and generality of results. Overall, variance in dishonest behavior was indeed accounted for by Honesty–Humility which was the only consistent predictor of cheating across the various experimental setups and beyond relevant covariates including other personality factors. The results thus corroborate that individual differences in ethical behavior can be accommodated by comprehensive models of personality structure in general and the Honesty–Humility factor in particular.  相似文献

Abstract

The purpose of sharing is to construct equivalent sets, making it an ideal context for analysing important quantitative concepts such as counting, equivalence and cardinality. Two studies analysed how four- and five-year-olds shared blocks in equal sharing and reciprocity conditions and their number inferences about one set after counting the other. The researcher asked children to share double and single blocks between two characters. They succeeded more in building equivalent shares in an equal sharing than reciprocity condition. Most children who shared correctly also made appropriate number inferences. To examine whether perceptual cues helped children share the blocks, a second study used Canadian $1 and $2 coins. A double block is twice the size of a single, whereas there is no visual cue about the value relation between coins because they are the same size. Unexpectedly, children shared equally well with blocks and coins, and most children made number inferences.  相似文献

While the social and ecological landscape of the twenty‐first century is worlds away from the historical‐cultural context in which the biblical myth‐symbols of the image of God and the knowledge of good and evil first emerged, Philip Hefner's understanding that Homo sapiens image God as created co‐creators presents a plausible starting point for constructing a second naïveté interpretation of biblical anthropology and a fruitful concept for envisioning and enacting our human future.  相似文献

Microstructure and deformation mechanisms at a nanoindentation in the lamellar colony of high Nb containing TiAl alloy have been studied using the focused ion beam and the transmission electron microscopy. Considerable deformation twins are observed around the nanoindentation, and a strain gradient is generated. A continuous change in the bending angle of the lamellar structure can be derived, and a strain-induced grain refinement process is observed as various active deformations split the γ grains into subgrains. In addition to all possible deformation mechanisms (ordinary dislocation, super-dislocation and deformation twining) activated due to the heavy plastic deformation, a 6-layer hexagonal (6H) long-period stacking ordered structure is identified for the first time near the contact zone and is thought to be closely related to the glide of partial dislocations.  相似文献
