Anorexia nervosa (AN) is perhaps the most lethal mental disorder, in part due to starvation-related health problems, but especially because of high suicide rates. One potential reason for high suicide rates in AN may be that those affected face pain and provocation on many fronts, which may in turn reduce their fear of pain and thereby increase risk for death by suicide. The purpose of the following studies was to explore whether repetitive exposure to painful and destructive behaviors such as vomiting, laxative use, and non-suicidal self-injury (NSSI) was a mechanism that linked AN-binge-purging (ANBP) subtype, as opposed to AN-restricting subtype (ANR), to extreme suicidal behavior. Study 1 utilized a sample of 787 individuals diagnosed with one or the other subtype of AN, and structural equation modeling results supported provocative behaviors as a mechanism linking ANBP to suicidal behavior. A second, unexpected mechanism emerged linking ANR to suicidal behavior via restricting. Study 2, which used a sample of 249 AN patients, replicated these findings, including the second mechanism linking ANR to suicide attempts. Two potential routes to suicidal behavior in AN appear to have been identified: one route through repetitive experience with provocative behaviors for ANBP, and a second for exposure to pain through the starvation of restricting in ANR.  相似文献

Recent research has demonstrated that interracial interactions, reminders of stigmatized identities, and exposure to ambiguous racism can deplete the self-control resources of minority group members. In the current study we examined whether hearing blatant racism expressed in an interracial context would deplete the self-control of Black participants and whether this depletion would be moderated by participants’ level of racial centrality. After listening to a Black or a White confederate express either support for racial profiling (racist condition) or increased campus parking fees (neutral condition), Black participants completed a Stroop color-naming task to assess self-control depletion. Participants experienced self-control depletion following interracial encounters, regardless of whether the views expressed were racist. As expected, however, racial centrality moderated the depletion effect when racism was involved, with participants higher in centrality showing greater depletion following an encounter with racism from a White partner.  相似文献

Recent conceptualisations of anxiety posit that equivocal findings related to the time-course of disengaging from threat-relevant stimuli may be attributable to individual differences in associative and rule-based processing. The current study was designed to test the hypothesis that strength of spider-fear associations would indirectly predict reported spider fear via impaired disengagement. One hundred and thirty-one undergraduate volunteer participants completed the Go/No-go Association Task, a visual search task, and self-report spider fear questionnaires. Stronger spider-fear associations were associated with reduced disengagement accuracy, whereas higher levels of reported spider fear were related to faster engagement with and disengagement from spiders. Bootstrapping multiple mediation analyses demonstrated that stronger-spider fear associations evidenced an indirect relationship with reported spider fear via reduced disengagement accuracy, highlighting the importance of fine-grained analyses of different aspects of cognitive bias. Results are discussed in terms of cognitive models of anxiety.  相似文献

The proposition that achievement goals are applicable to the social domain was examined in four studies. Study 1 established that different orientations toward developing or demonstrating social competence can be seen in individuals' responses to open-ended questions about their social goals and social competence. Studies 2 through 4 evaluated a new survey measure of social achievement goals. Exploratory and confirmatory factor analyses confirmed the hypothesized model of social achievement goals. Convergent and discriminant validity for the new measure of social achievement goals was established. In line with hypotheses, a social development goal was associated with adjustment and a social demonstration-avoid goal was associated with maladjustment both concurrently and longitudinally. A social development goal also was positively related to instructor ratings of students' social adjustment in small classroom settings. A social demonstration-approach goal was most often unrelated to adjustment. The importance of social achievement goals for a comprehensive understanding of social motivation and adjustment is discussed.  相似文献

The present study was designed to assess sex-dimorphic color preferences in children with gender identity disorder (47 boys, 18 girls), clinical controls (65 boys, 35 girls), and community controls (65 boys, 35 girls). The mean age of the children was 7.63 years (range?=?3–12 years). Children were shown a hexagon-shaped display of 144 colors extracted from PowerPoint?. Each child was asked to choose his or her three favorite colors (Trials 1–3) by pointing to them, naming them, and then to provide a justification for each choice. From the entire array, children labeled a total of 11 different colors: black, blue, brown, gray, green, orange, pink, purple, red, white, and yellow. For three of the colors (blue, pink/purple, and red), there was evidence for normative sex differences in color preference, and, for the colors blue and pink/purple, the gender-referred children showed inverted patterns of color preference. For the color blue, luminance values showed that the gender-referred boys and control girls preferred lighter shades, whereas the gender-referred girls and control boys preferred darker shades. Qualitative analysis indicated that gender-specific justifications were uncommon, even for the sex-dimorphic colors. Gender-referred children showed inverted gender-stereotyped color preferences, which are likely related to their more general pattern of cross-gender identification. Principles of gender-differentiated development derived from gender-schema theory are used to explain the group differences in color preferences.  相似文献

A new manual search method was used to investigate the impact of naming on object individuation in 12-month-old infants. In Experiment 1, on a two-word trial, an experimenter looked into a box while the infant was watching and provided two labels (e.g., "Look, a fep!" and "Look, a wug!"). On a one-word trial, the experimenter instead repeated the same label (e.g., "Look, a zav!"). After the infant retrieved one object from the box, subsequent search behavior was recorded. Infants searched more persistently (i.e., for a longer duration) after hearing two labels than one, suggesting that hearing two labels led the infants to expect two objects inside the box. In Experiment 2, infants' search behavior did not differ depending on whether they heard one or two emotional expressions, suggesting that the facilitation effect observed in Experiment 1 may be specific to linguistic expressions. Thus, we provide the first evidence that infants as young as 12 months are able to use intentional and referential cues to guide their object representations. These findings also suggest that a rudimentary version of the mutual-exclusivity constraint may be functional by the end of the first year.  相似文献

This study sought to understand school-level influences on aggressive behavior and related social cognitive variables. Participants were 5106 middle school students participating in a violence prevention project. Predictors were school-level norms opposing aggression and favoring nonviolence, interpersonal climate (positive student–teacher relationships and positive student–student relationships), and school responsiveness to violence (awareness and reporting of violence and school safety problems). Outcomes were individual-level physical aggression, beliefs supporting aggression, and self-efficacy for nonviolent responses. School norms and both interpersonal climate variables had effects on all three outcomes in theorized directions. Only one of the responsiveness measures, awareness and reporting of violence, had theoretically consistent effects on all outcomes. The other, school safety problems, affected self-efficacy later in middle school. Evidence of gender moderation was generally consistent with greater influence of school-level factors on female adolescents. Discussion focuses on implications in light of previous research and intervention possibilities.  相似文献

The cognitive and motivational processes by which happy people are able to artfully sustain their happiness are examined within a subjectivist construal approach. Individuals who perceive themselves as happy respond to ordinary experiences differently than their less happy peers. Research from our laboratory has revealed these differences in a variety of contexts, including people's responses to decisions, their reactions to social comparisons, and their interpretations of life events. Our research has also shown that, after experiencing failure, happy people tend not to engage in negative self-reflection and are able to perform subsequent tasks without dwelling. Although happy people experience negative moods and negative life events similar to those of less happy people, they evaluate these events less negatively and respond to them in more positive, affirming ways. These group differences suggest a number of possible ways to sustainably enhance happiness, and current experimental interventions designed to test the effectiveness of several intentional happiness-increasing strategies are discussed. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献
