The hedonic value of an outcome can be influenced by the alternatives to which it is compared, which is why people expect to be happier with outcomes that maximize comparative value (e.g., the best of several mediocre alternatives) than with outcomes that maximize absolute value (e.g., the worst of several excellent alternatives). The results of five experiments suggest that affective forecasters overestimate the importance of comparative value because forecasters do not realize that comparison requires cognitive resources, and that experiences consume more cognitive resources than do forecasts. In other words, because forecasters overestimate the extent to which they will be able to think about what they did not get while experiencing what they got. 相似文献

ABSTRACT Paulhus and Williams (2002) identified a “Dark Triad” comprising the following related personality styles: narcissism, psychopathy, and Machiavellianism. The heterogeneity found in narcissism and psychopathy raises the possibility of a second triad made up of emotional vulnerability and dark traits (i.e., the vulnerable dark triad; VDT). Along with vulnerable narcissism and Factor 2 psychopathy, the third member of the hypothesized VDT is borderline personality disorder (BPD). Using a sample of 361 undergraduates, we examine the relations between these constructs and their relations with criterion variables, including personality, environmental etiological factors (e.g., abuse), and current functioning (e.g., psychopathology, affect). The results suggest that the VDT constructs are significantly related to one another and manifest similar nomological networks, particularly vulnerable narcissism and BPD. Although the VDT members are related to negative emotionality and antagonistic interpersonal styles, they are also related to introversion and disinhibition. Ultimately, it seems there is a “dark continuum” of pathological personality traits that differ primarily in relation to negative and positive emotionality and disinhibition. 相似文献

Measurement invariance of a one-factor model of effortful control (EC) was tested for 853 low-income preschoolers (M age = 4.48 years). Using a teacher-report questionnaire and seven behavioral measures, configural invariance (same factor structure across groups), metric invariance (same pattern of factor loadings across groups), and partial scalar invariance (mostly the same intercepts across groups) were established across ethnicity (European Americans, African Americans and Hispanics) and across sex. These results suggest that the latent construct of EC behaved in a similar way across ethnic groups and sex, and that comparisons of mean levels of EC are valid across sex and probably valid across ethnicity, especially when larger numbers of tasks are used. The findings also support the use of diverse behavioral measures as indicators of a single latent EC construct. 相似文献

Practice of different tasks in a random order induces better retention than practicing them in a blocked order, a phenomenon known as the contextual interference (CI) effect. Our purpose was to investigate whether the CI effect exists in sequence learning, such that practicing different sequences in a random order will result in better learning of sequences than practicing them in blocks, and whether this effect is affected by aging. Subjects practiced a serial reaction time task where a set of three 4-element sequences were arranged in blocks or in a random order on 2 successive days. Subjects were divided into 4 groups based on a 2-GROUP (young or old) by 2-ORDER (random or blocked practice) between-subject design. Three days after practice (Day 5), subjects were tested with practiced and novel sequences to evaluate sequence-specific learning. The results replicate the CI effect in sequence learning in both young and older adults. Older adults retained sequences better when trained in a random condition than in a blocked condition, although the random condition incurs greater task switching costs in older adults during practice. Our study underscores the distinction between age-related effects on learning vs. performance, and offers practical implications for enhancing skill learning in older adults. 相似文献

Cognitive behavior therapy (CBT) is an effective treatment for bulimia nervosa (BN). However, among patients with BN, symptom improvement is more pronounced for behavioral eating symptoms (i.e., bingeing and purging) than for body image disturbance, and the persistence of body image disturbance is associated with relapse. The need for more effective body image interventions led to the development of mirror exposure, which focuses on encouraging patients to view themselves in a holistic, nonjudgmental, mindful fashion. Behavioral manifestations of body image disturbance—body checking and avoidance—are also targeted in order to reduce and eliminate such behaviors and their associated preoccupation and distress. A preliminary trial of Body Image Exposure has shown promise, but it has not yet been tested in the context of CBT for BN. The case of “Sara” illustrates the application of this targeted treatment for body image disturbance. Central clinical issues around the perceptual, cognitive, and behavioral components of body image are delineated as they arose in treatment, as are issues of motivation and compliance. Treatment was associated with improvement in eating symptoms, body image, and mood. 相似文献

Cognitive neuroscience literature suggests a strong dissociation between the ability to mentally transform object and body stimuli (Hegarty & Waller, 2004). However, little is known about how this ability changes with age. This dissociation was explored in 20 younger (19-24 years) and 20 older (65-87 years) adults. Mental rotation of object stimuli was demonstrated for both age groups, suggesting that the neuro-cognitive network involved with performing (object-based) mental transformations is relatively preserved in older age. Compared to young adults, older adults displayed the greatest decline in performance efficiency for the whole-body task. The authors propose that an age-related decline in the integrity of body-schema information may account for this change. 相似文献

Participants rated a series of photographs that depicted well-known male and female athletes in a sexualized fashion or not. In general, sexualized targets were perceived as more attractive but as less competent than non-sexualized targets, and for ratings of competence, sexualization effects were greater for female targets. Sexualization had no effects on women’s perceptions of the competence of male targets, whereas for men, sexualization affected their perceptions of the competence of both male and female targets, although the influence of sexualization was stronger for female targets than it was for male targets. These findings suggest that the gender of the target and of the perceiver needs to be considered when evaluating the influences of sexualization. The implications of these findings are discussed within the context of objectification theory, which has focused on the objectification of women by women. 相似文献

Foreign language proficiency is a critical skill in which many U.S. military personnel receive extensive training. However, very little research has examined the factors associated with the successful transfer of this training. This study therefore investigates the impact of individual and contextual variables on two different types of foreign language skill transfer measures in a military context. Archival data were analyzed from 133 U.S. Army Special Forces (Green Berets) teams, including 919 Soldiers who had completed job-required foreign language training. Results indicate that initial skill acquisition had a positive impact on both the maintenance and generalization of language skills. The posttraining time interval between training and transfer measurement was negatively associated with skill maintenance, suggesting significant skill decay over time. The team context also accounted for significant variability in skill transfer, and the team mean skill level moderated the relationship between individual initial skill and subsequent generalization to job performance. 相似文献

There are several generating units available to meet the load demand on any given day. The mixed‐integer programme case engages generating units that can be shut down or operated between minimum and maximum output levels within a specific time demand block. An examination of these conditions espouses the utilization of renewable energy technology as a reliable power generation source and its effectiveness and augmentation in a robust, heavily subjugated thermal generation system. The mixed‐integer problem has the predisposition to generate many subproblems during the computation. However, with careful selection of the parameters in the model, the challenges are easily overcome. Hydroelectric energy is significant from an operational standpoint as it requires little or no ramp‐up time, commonly found in many combustion technologies. The essential load‐following capability, peaking capacity and voltage stability attributes render hydroelectric energy as a significant part in ensuring reliable electricity service and in meeting customer needs in a market‐driven industry. When this renewable resource is combined with the thermal generation, an improved reliability function is apparent. Yet, in order to minimize the environmental effects inherent in this type of energy resource, the renewable power supply is expected to produce an effectual, consistent output. The integration of renewable generation within the electrical system entails intricate analysis of the transmission line upgrades throughout the system. These upgrades are designed to relieve congestion, improve reliability and provide voltage support by thoroughly evaluating the alternatives to accommodate the new expansion efforts. This paper examines the system integration of renewable generators, via simulated studies, in the context of electrical operations from the hydroelectric generation perspective.
