Terror management theory (TMT) posits that bolstering self-esteem buffers mortality concerns; accordingly, in past research, heightening mortality salience (MS) increases self-enhancement. However, risky self-esteem-relevant decisions often present a choice between enhancing self-esteem by striving for excellence and protecting self-esteem by avoiding potential failure. Which strategy is preferred under MS? Combining TMT with insights from Steele, Spencer, and Lynch's (1993) resource model, the authors hypothesized and found that MS leads high, but not low, self-esteem participants faced with a risky decision to pursue opportunities for excellence despite substantial risk of failure (Studies 1 and 2); in Study 3, using a more impactful decision, this effect was replicated and it was furthermore found that mortality-salient low-self-esteem participants become more risk-averse. Furthermore, in Study 2, a self-affirmation prime, previously shown to reduce MS-induced defenses, eliminated the self-enhancement effect among high-self-esteem participants. Implications for understanding self-esteem, TMT, and risky decision making are briefly discussed.  相似文献

Given the rise in chronic kidney disease (CKD) in both children and adults, CKD has recently been targeted as a public health priority. Childhood onset kidney disease is generally a noncurable and progressive condition that leads to kidney failure by early adulthood. Fortunately, improved identification of kidney problems allows for early intervention, which is thought to slow progression toward end-stage renal disease. In addition, medical interventions for pediatric end-stage renal disease have also improved, allowing children to take advantage of lifesaving renal replacement treatments such as dialysis and kidney transplantation. In spite of improvements in identification and treatment, CKD causes both direct and indirect insults to a variety of organ systems. This paper reviews recently published studies pertaining to the neurocognitive and psychosocial impact of CKD on children of various ages and at various stages of kidney failure. Specific attention is focused on summarizing peer reviewed research that describes associations between kidney functioning and cognitive functioning, language acquisition, visual spatial abilities, memory, and executive functioning. In addition, peer reviewed research describing psychosocial outcomes associated with CKD related to academic achievement, social-behavioral functioning, and quality of life are summarized. The authors also identified disease-specific factors that likely mediate neurocognitive outcomes (e.g., anemia, hypertension, cardiovascular) and endorse the importance of continued interdisciplinary research collaborations that will provide a better understanding of the mechanisms responsible for improved neurocognitive functioning after transplantation. The authors conclude this review by describing a multicenter, prospective, longitudinal, National Institutes of Health funded study that is currently examining the developmental outcomes of children with mild to moderate CKD. The authors speculate that the Chronic Kidney Disease in Children Prospective Cohort Study (CKiD) findings will provide additional evidence-based guidance for clinicians and researchers working with children and adolescents with deteriorating kidney function to improve medical and developmental outcomes.  相似文献

By the age of 3, children easily learn to name new objects, extending new names for unfamiliar objects by similarity in shape. Two experiments tested the proposal that experience in learning object names tunes children's attention to the properties relevant for naming—in the present case, to the property of shape—and thus facilitates the learning of more object names. In Experiment 1, a 9-week longitudinal study, 17-month-old children who repeatedly played with and heard names for members of unfamiliar object categories well organized by shape formed the generalization that only objects with similar shapes have the same name. Trained children also showed a dramatic increase in acquisition of new object names outside of the laboratory during the course of the study. Experiment 2 replicated these findings and showed that they depended on children's learning both a coherent category structure and object names. Thus, children who learn specific names for specific things in categories with a common organizing property—in this case, shape—also learn to attend to just the right property—in this case, shape—for learning more object names.  相似文献

Williams syndrome (WS) is a rare genetic disorder that results in profound spatial cognitive deficits. We examined whether individuals with WS have intact perception of biological motion, which requires global spatial integration of local motion signals into a unitary percept of a human form. Children with WS, normal mental-age-matched children, and normal adults viewed point-light-walker (PLW) displays portraying a human figure walking to the left or right. Children with WS were as good as or better than control children in their ability to judge the walker's direction, even when it was masked with dynamic noise that mimicked the local motion of the PLW lights. These results show that mechanisms underlying the perception of at least some kinds of biological motion are unimpaired in children with WS. They provide the first evidence of selective sparing of a specialized spatial system in individuals with a known genetic impairment.  相似文献

Adapted methods of behavioral assessment to assess home and school functioning in a way that maps directly to the Diagnostic and Statistical Manual of Mental Disorders (4th ed., [DSM-IV]; American Psychiatric Association, 1994). The study was conducted in a school-based sample with 5- to 12-year-old children referred to a school intervention team. A multigate set of procedures was used to assign children to one of 3 groups: attention deficit hyperactivity disorder (ADHD), inattentive group; ADHD, combined group; and a non-ADHD control group. The ADHD Rating Scale-IV was used to assess parent and teacher ratings of ADHD symptoms as delineated in DSM-IV. The findings suggest that the use of a fixed cutoff point (i.e., 6 or more symptoms), which is employed in the DSM-IV, is often not the best strategy for making diagnostic decisions. The optimal approach depends on whether diagnostic information is being provided by the parent or teacher and whether the purpose of assessment is to conduct a screening or a diagnostic evaluation. Also, the results indicate that a strategy that aggregates symptoms in the order in which they are accurate in predicting a diagnosis of ADHD is a more effective strategy than the approach used in DSM-IV, which aggregates any combination of a specific number of items. Implications for using methods of behavioral assessment to make diagnostic decisions using DSM-IV criteria are discussed.  相似文献

Collective guilt from harm one's group has caused an out‐group is often undermined because people minimize or legitimize the harm done (i.e., they generate exonerating cognitions). When a group action has harmed both the in‐group and an out‐group, focusing people on “self‐harm”—ways in which the in‐group has harmed itself—may elicit more collective guilt because self‐harm is less likely to be exonerated. In Study 1, American participants who focused on how the invasion of Iraq had harmed the United States expressed greater collective guilt over harm inflicted on the people of Iraq than those who focused on Iraqi suffering. Study 2 showed that this effect is due to reductions in exonerating cognitions among people focused on self‐harm. We consider the implications of these findings for intergroup reconciliation, particularly in situations where two groups have been involved in open conflict.  相似文献

There is a need to promote growth past basic reading proficiency toward the more substantial idea of reading maturity. The reading maturity construct has a history of being valued, at least in principle. However, it is a complex construct, and this makes its measurement challenging. The present research study addressed aspects of this challenge by using data collected from an instrument called The Reading Maturity Survey, administered twice to 382 college students, to help validate the instrument and to add one piece of validation evidence to the internal structure of the reading maturity construct. Structural equation modeling (SEM) was used to identify the latent literacy constructs and to examine the relationships between these constructs. The findings contribute to further psychometric validation of The Reading Maturity Survey, and add one new piece of quantitative evidence supporting the theory-based construct of reading maturity. Because this study provides some preliminary evidence of viable ways to both measure and define this construct, our hope is that the findings would move the reading field one step closer to being able to better recognize an overarching unified construct of reading maturity, perhaps eventually (re)establishing it as a goal that literacy education could pursue.  相似文献

The aim of this study was to determine whether characteristics of leadership identified among adults also exist among young gifted children. The study was conducted in Israel among 63 gifted children aged 10 to 14 who completed the Leadership Questionnaire, constructed especially for this study. The characteristics found to distinguish between high and low scorers on leadership were responsibility, desire to dominate, consistency, physical energy, achievement orientation, expressive and persuasive powers, cooperation, adaptability, daring, self-confidence, and emotional equilibrium. The results confirmed our hypothesis that the characteristics of leadership identified in adults do exist among gifted children.  相似文献

Several philosophers have argued that if we examine our lives in context of the cosmos at large, sub specie aeternitatis, we cannot escape life's meaninglessness. To see our lives as meaningful, we have to shun the point of view of the cosmos and consider our lives only in the narrower context of the here and now. I argue that this view is incorrect: life can be seen as meaningful also sub specie aeternitatis. While criticizing arguments by, among others, Simon Blackburn, Nicholas Rescher, and Thomas Nagel, I show that what determines assessments of the meaning of a life are the standards of meaningfulness one endorses rather than the size of the context in which that life is assessed. Employing non-demanding standards of meaningfulness to assess a life is compatible with examining it in the context of the cosmos at large. That is also the case if we accept Nagel's claim that to examine a life sub specie aeternitatis is to examine it externally, impersonally and objectively: life can be evaluated as meaningful also when under these perspectives if the standards of meaningfulness we adopt are not overly challenging. Nor does the contingency of our existence, realized sub specie aeternitatis, render our life meaningless. Contrary to a commonly accepted view, then, examining our lives sub specie aeternitatis does not necessitate that we see them as meaningless.  相似文献

This study investigated the relationship of information-seeking from managers and coworkers, number of prospecting methods used, and number of joint sales calls the new hire went on with managers and coworkers to sales productivity during the first six months of employment. This study also investigated whether age was directly related to sales productivity, indirectly related through its influence on the other independent variables, or moderated the relationship between the independent variables and sales productivity. Results showed that age and going on joint sales calls with managers and coworkers were positively related to sales productivity. Age also served as a moderator. Older new hires who used a variety of prospecting techniques, and younger new hires who asked their peers for information about job and organizational procedures were better performers. The implications of these results for organizations are discussed.  相似文献
