As part of an ongoing study on the prediction of suicide, a replication study was carried out on the Neuropsychiatric Hospital Suicide Potential Scale (NPHSPS), a recently constructed schedule for prediction of potentiality for committed suicide among hospitalized neuropsychiatric patients at the time of release from the hospital. The population consisted of 54 patients who had committed suicide and 50 patients who had not. Overall accuracy of the scale was 81.7 percent, with 95.2 percent accuracy for prediction of the high risk group and 80.0 percent accuracy for prediction of nonsuicidal controls. By computation of posterior probability, the scale is shown to increase accuracy of prediction more than five-fold over use of the base rate (or prior probability) alone, but it is also evident the level of prediction of suicide is still too minimal to permit individual clinical application. 相似文献

Self‐Control Moderates Decision‐Making Behavior When Minimizing Losses versus Maximizing Gains 下载免费PDF全文
We examined (1) whether people would be more responsive to the delayed consequences of their decisions when attempting to minimize losses than when attempting to maximize gains in a history‐dependent decision‐making task and (2) how trait self‐control would moderate such an effect. In two experiments, participants performed a dynamic decision‐making task where they chose one of two options on each trial. The increasing option always gave a smaller immediate reward but caused future rewards for both options to increase. The decreasing option always gave a larger immediate reward but caused future rewards for both options to decrease. In Experiment 1 where the two options had equivalent expected value in the long run, participants were more prone to select the increasing option, which yielded larger benefits on future trials, in the loss‐minimization condition than in the gain‐maximization condition. Trait self‐control moderated the effect of losses by enhancing the effect for low self‐control participants while attenuating it for high self‐control participants. In Experiment 2 where selecting the increasing option was suboptimal, low self‐control participants still attempted to reduce losses on future trials by selecting the increasing option more often than high self‐control participants. These results suggest that decision makers value delayed consequences of their actions more in a losses domain relative to a gains domain and low self‐control individuals are more susceptible to such an effect.

The authors examined relations between implicit and explicit Hope of Success (HS) and Fear of Failure (FF) and memory and liking for successful and unsuccessful peers. Implicit motives were expected to predict memory and explicit motives to predict liking of peers. Results from 106 American and 79 Singaporean students supported the implicit–explicit motive distinction as well as a link between HS and the successful peer and between FF and the unsuccessful peer. In both samples, explicit HS predicts liking while implicit HS predicts memory about the successful peer, and implicit FF predicts memory about the unsuccessful peer. Findings indicate achievement motives affect interest in and reaction towards peers and provide evidence for differential validity of implicit and explicit motives. 相似文献

Changing the way in which children respond significantly improves performance across a variety of cognitive domains. However, the basis for this response‐mode effect is unknown. To address this issue, the current study tested 78 preschool children on a measure of executive functioning (the windows task: Hala & Russell, 2001 ). The task requires children to point to an empty box to receive a box with a treat in it. There were four versions of the task, differing only in the way in which children made their responses. Children in the baseline condition, who pointed with their finger, performed poorly. However, children in three alternative response‐mode conditions won the treat significantly more often. Strikingly, even children who pretended to be pointing with an arrow – but were in reality pointing with their finger – performed significantly better than baseline. We suggest that non‐standard response modes encourage children to reflect on their actions and that this reduces the number of unreflective errors they make. The findings demonstrate that response‐mode effects do not depend on the presence of a physical means of responding (such as an arrow), but can be achieved via a purely cognitive means (such as engaging in pretence). 相似文献

Traditional perspectives have envisaged intelligence as one entity dominated by a single set of abilities (i.e. cognitive abilities), whereas modern perspectives have defined intelligence in various shapes (e.g. linguistic, musical and interpersonal intelligences). By the same token, traditional perspectives have examined stupidity as one set of inabilities (i.e. cognitive inabilities). However, it is not clear whether modern perspectives have discussed whether stupidity exists in various forms—in the same way as they have envisaged intelligence. To address this limitation, 257 university members were asked to share what they perceived as being stupid educational and technological practices in their institutions. Analysis of the data suggested three concepts were important to the members: moral, spatial and administrative stupidities. That is, stupidity is perceived to come in the form of failing to meet certain moral, spatial and administrative values. This implies that modern perspectives may conceptualise stupidity differently from traditional perspectives, seeing it as going beyond cognitive inabilities and viewing it as existing in various forms (e.g. moral, spatial and administrative stupidities). Thus, there are multiple stupidities as there are multiple forms of intelligence. A strength of this research is that it views stupidity through an organisational and qualitative lens, although some may traditionally expect such a topic to be examined quantitatively through psychometric and biological approaches. 相似文献

Elective cosmetic surgeries are increasing in the American population with reasons linked to body image disturbance and body dysmorphic disorder (BDD). Little research exists documenting the continuum of body image disturbance and its relationship to seeking surgery. The present research examined data from 544 participants, 55 of whom were diagnosable with BDD. Using assessments for body image disturbance, problematic coping strategies, and BDD symptomatology, results provided evidence for a continuum of body image distress. Logistic regression analysis supported the hypothesis that increased levels of body image disturbance and one type of problematic coping strategy (Appearance Fixing) predicted consideration of cosmetic surgery. Of participants diagnosable with BDD, those who considered cosmetic surgery showed more severe body image disturbance and problematic coping than those who did not consider surgery. These results have implications for pre-surgical assessment as well as psychological interventions rather than invasive medical interventions. 相似文献

This study examined the relationship between the developmental trajectories of neuropsychological functioning and ADHD symptomatology in a longitudinal sample of children ages 9 to 14. Participants and measures were derived from the Multimodal Treatment Study for ADHD including 534MTA participants and 254 normal controls. Despite improvement over time, MTA participants continued to receive higher ratings of ADHD symptomatology and exhibit greater difficulties across the majority of neuropsychological outcomes. No relations were found between improvements in neuropsychological functioning and ADHD symptomatology over time. Findings provide support for the persistence of neuropsychological functioning and ADHD symptomatology. Findings did not support the hypothesized relation between improvements in frontally-mediated neuropsychological functioning and ADHD symptomatology possibly due to the brief 1-year lag and limited assessment battery. Findings are discussed in relation to neuropsychological development including recommendations for future research. 相似文献

Two groups of mothers and their infants (24 infants, mean age=3.5 months and 24 infants, mean age=5.5 months) were video‐ and audio‐taped in their homes while playing with a Jack‐in‐the‐box. The mean fundamental frequency of spontaneous surprise exclamations of mothers when opening the toy were analysed, and infant and maternal facial expressions of surprise were coded in three regions of the face. A t‐test established that significantly more of the older children in comparison with younger children showed surprise (t=?2.96, df=46, p<0.005, 2‐tailed). Twenty‐nine per cent of the younger infants, in comparison with 67% of the older children showed facial expressions of surprise. A t‐test of maternal pitch height (Hz) indicated that mothers exclaimed in surprise with a higher pitch when the child did not show a surprise facial expression (mean=415.61 Hz) in comparison with the child showing surprise (mean=358.97 Hz; t=2.9, df=46, p=0.006, 2‐tailed). A multiple regression established that infant's expression was a stronger predictor of maternal vocal pitch than was the age of the infant. These results are discussed in terms of maternal use of emotional expressions as ‘social signals’. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献
