Lateralization of cognitive processes and motor functions has been demonstrated in a number of species, including humans, elephants, and cetaceans. For example, bottlenose dolphins (Tursiops truncatus) have exhibited preferential eye use during a variety of cognitive tasks. The present study investigated the possibility of visual lateralization in 12 belugas (Delphinapterus leucas) and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) located at two separate marine mammal facilities. During free swim periods, the belugas and Pacific white-sided dolphins were presented a familiar human, an unfamiliar human, or no human during 10–15 min sessions. Session videos were coded for gaze duration, eye presentation at approach, and eye preference while viewing each stimulus. Although we did not find any clear group level lateralization, we found individual left eye lateralized preferences related to social stimuli for most belugas and some Pacific white-sided dolphins. Differences in gaze durations were also observed. The majority of individual belugas had longer gaze durations for unfamiliar rather than familiar stimuli. These results suggest that lateralization occurs during visual processing of human stimuli in belugas and Pacific white-sided dolphins and that these species can distinguish between familiar and unfamiliar humans. 相似文献

This study explored television viewing of the September 11 attacks in 99 survivors of the Oklahoma City bombing and examined the relationships of event-related television viewing with concerns about safety and danger in survivors with and without bombing-related posttraumatic stress disorder. The number of hours of viewing September 11 television coverage was related to worry about personal and family danger and to increased checking on loved ones but not to September 11–related posttraumatic responses. Some bombing survivors discontinued September 11 media contact due to fear. The findings suggest the importance of monitoring television viewing in survivors of prior incidents. 相似文献

Peer victimization is a frequent occurrence for many adolescents; however, some of the psychometric properties of self-report scales assessing these experiences remain unclear. Furthermore, with an increase in access to technology, electronic aggression should also be considered. The authors examined the psychometric properties of the Multidimensional Peer Victimization Scale (MPVS; Mynard & Joseph, 2000), and developed versions to include the assessment of electronic aggression according to whether the adolescent was the target or perpetrator of peer victimization. A total of 371 (191 girls and 180 boys; Mage = 13 years 4 months, SDage = 1 year 2 months) adolescents in the United Kingdom completed the MPVS including five newly developed items assessing electronic aggression, a version of the MPVS designed to assess victimization perpetration, and a measure of self-esteem. Confirmatory factor analyses yielded a five-factor structure comprising: Physical, social manipulation, verbal, attacks on property, and electronic for both scales. Convergent validity was established through negative associations between the victimization scales and self-esteem. Sex differences also emerged. One revised scale and one new scale are subsequently proposed: The MPVS–Revised and the Multidimensional Peer Bullying Scale. 相似文献

Abstract: Radical meta‐normative skepticism is the view that no standard, norm, or principle has objective authority or normative force. It does not deny that there are norms, standards of correctness, and principles of various kinds that render it possible that we succeed or fail in measuring up to their prerogatives. Rather, it denies that any norm has the status of commanding with objective authority, of giving rise to normative reasons to take seriously and follow its demands. Two powerful transcendental arguments challenge this view. First, skepticism is said to be self‐defeating: Settling what to accept, and in particular whether to accept skepticism, appears to be a reason‐guided enterprise. How can skeptics coherently support their view by citing reasons in their favor after they just rejected them throughout? Second, there is the practical‐deliberative version, most recently developed by David Enoch: We are essentially deliberative creatures. Yet deliberation appears to require that there are correct answers in the form of normative reasons to our practical questions. Thus confidence in the sensible nature of deliberation should inspire confidence in reasons. The essay undermines both transcendental arguments by demonstrating, first, how to support skepticism without deserting its tenets, and, second, how to deliberate in skeptical fashion. 相似文献

ABSTRACT Demonstrations of memory changes in those at risk for Alzheimer's disease by the presence of the APOE e4 allele have been inconsistent to date. The present study went beyond traditional analyses of central tendency (i.e., group differences on mean test scores) and also conducted distribution analyses to search for subtle cognitive differences in subgroups of normal-functioning elderly persons with the APOE e4 genotype. The results of the study revealed that (a) the e4 and non-e4 groups failed to differ in terms of their mean scores on tests of memory and verbal skills; and (b) relative to the non-e4 group, the e4 subjects had significantly greater heterogeneity of variance on the memory measures but not on fundamental verbal skills. Logistic regression analyses indicated that the discrepancy in scores on the memory measures was a significant predictor of genotype group membership (82% correct classification rate). Implications of these findings for the detection of a preclinical phase of AD are discussed. 相似文献

Abstract Marguerite La Caze has recently published a stimulating analysis of the emotions of envy and resentment in which she argues that to envy others for a benefit they have received or to resent them for such a reason can be ethically acceptable in cases where that benefit has been unjustly obtained (La Caze, 2001). I question this on the ground that the judgement that the benefit has been unjustly obtained plays a more complex role in the structure of envy and resentment than La Caze allows and should alter the nature of the feeling that is evoked. From the perspective of virtue ethics there is nothing creditable about still feeling envy or resentment in such circumstances. 相似文献

Subjective well-being (SWB) comprises individual differences in life satisfaction (LS), positive affect (PA), and negative affect (NA), and is typically conceptualized as an important life outcome. In contrast, Shmotkin (Rev Gen Psychol 9:291–325, 2005) proposed that SWB is a dynamic and agentic system that promotes optimal functioning, and is organized within individuals as configurations of LS, PA, and NA. We investigated three fundamental features of this novel framework. A 3-year, two-wave longitudinal study (N = 446 Canadian students; Mage = 18.67; 73 % female) was undertaken. The same set of five SWB configurations were observed at each time point, including congruous and incongruous profiles. Consistent with the hypothesized dynamic nature of the SWB system intraindividual stability in SWB configurations (operationalized in terms of categorical cluster membership and prototypicality scores) was moderate. In support of the proposed responsive nature of the SWB system, changes over time in individuals’ SWB configurations were predicted by changes in psychological, physical, and interpersonal functioning. Consonant with the proposed promotive role of the SWB system, positive functioning and changes in functioning over time were predicted by individuals’ SWB configurations and changes in configurations. The present work provides support for the proposed dynamic and agentic nature of SWB. Unique insights offered by a configural perspective on SWB are discussed. 相似文献

Work conditions and employees' self-set goals: goal processes enhance prediction of psychological distress and well-being 总被引:3,自引:0,他引:3
Although previous theory and research suggest that employee well-being should be predicted by work conditions (viz., Karasek and colleagues' job demands-control-social support [J-DCS] model), other factors are also likely to be important. In this study, the authors consider correlates of employee psychological distress and well-being using a goal-focused approach grounded in Ford's (1992) motivational systems theory. Specifically, work conditions and midlevel work goal processes (WGP) were examined in a questionnaire study of health care employees. Regarding predictions derived from the J-DCS model, the authors found full support for the iso-strain, partial support for the nonlinearity, and no support for the buffer hypothesis. Of importance, however, WGP (i.e., cognitions and emotions involved in the pursuit of self-set work goals) explained variance in job satisfaction, burnout, depression, and somatic complaints, over and above that of the J-DCS model. This suggests that investigation of WGP can enhance our understanding of employee psychological distress and well-being. 相似文献

In 2001, Xitco et al. (Anim Cogn 4:115–123) described spontaneous behaviors in two bottlenose dolphins (Tursiops truncatus) that resembled pointing and gaze alternation. The dolphins spontaneous behavior was influenced by the presence of a potential receiver, and the distance between the dolphin and the receiver. The present study adapted the technique of Call and Tomasello [(1994) J Comp Psychol 108:307–317], used with orangutans to test the effect of the receivers orientation on pointing in these same dolphins. The dolphins directed more points and monitoring behavior at receivers whose orientation was consistent with attending to the dolphins. The results demonstrated that the dolphins pointing and monitoring behavior, like that of apes and infants, was linked to the attentional behavior of the receiver. 相似文献

Conflicting findings have been reported regarding the relationship between the potential lethality of acts of deliberate self-harm (DSH) and suicidal intent, and how each relates to patient characteristics. This study examines the relationship of suicidal intent of DSH to lethality, the relationship of both to patient characteristics, and determines if intent or lethality are risk factors for repetition of DSH. Potential lethality and Suicide Intent Scale (SIS) scores for DSH episodes were examined in a representative sample of 150 patients presenting to a general hospital. Follow-up interviews were completed 12 to 20 months later. Lethality was strongly associated with high intent. Both lethality and intent were associated with male gender. Suicidal intent but not lethality was associated with the presence of psychiatric disorder and depression. Intent was significantly correlated with hopelessness scale score. Although intent was correlated with both depression and self-esteem scale scores, these correlations became nonsignificant when the effect of hopelessness was removed. Repetition of DSH during the follow-up period was related to neither lethality nor intent scores for the original episodes. Lethality and suicidal intent, although related, have somewhat different correlates. Both should be considered when assessing DSH patients, but their relationship to further suicidal behavior does not appear to be straightforward. 相似文献
