In §54 of the Grundlagen, Frege advances an interesting proposal on how to distinguish among different sorts of concepts, only some of which he thinks can be associated with number. This paper is devoted to an analysis of the two criteria he offers, isolation and non-arbitrary division. Both criteria say something about the way in which a concept divides its extension; but they emphasize different aspects. Isolation ensures that a concept divides its extension into discrete units. I offer two construals of this: isolation as discreteness, i.e. absence of overlap, between the objects to be counted; and isolation as the drawing of conceptual boundaries. Non-arbitrary division concerns the internal structure of the units we count: it makes sure that we cannot go on dividing them arbitrarily and still find more units of the kind. Non-arbitrary division focuses not only on how long something can be divided into parts of the same kind; it also speaks to the way in which these divisions are made, arbitrarily or non-arbitrarily, as well as to the compositional structure of the objects divided. 相似文献

Speeded detection and increased distraction in fear of spiders: evidence from eye movements 总被引:6,自引:0,他引:6
Anxiety patients exhibit attentional biases toward threat, which have often been demonstrated as increased distractibility by threatening stimuli. In contrast, speeded detection of threat has rarely been shown. Therefore, the authors studied both phenomena in 3 versions of a visual search task while eye movements were recorded continuously. Spider-fearful individuals and nonanxious control participants participated in a target search task, an odd-one-out search task, and a category search task. Evidence for disorder-specific increased distraction by threat was found in all tasks, whereas speeded threat detection did not occur in the target search task. The implications of these findings for cognitive theories of anxiety are discussed, particularly in relation to the concept of disengagement from threat. 相似文献

The present study investigated Big Five personality trait development in the transition to early adolescence (from the fifth to eighth grade). Personality traits were assessed in 2,761 (47% female) students over a 3‐year period of time. Youths’ self‐reports and parent ratings were used to test for cross‐informant agreement. Acquiescent responding and measurement invariance were established with latent variable modeling. Growth curve models revealed three main findings: (a) Normative mean‐level changes occurred for youths’ self‐report data and parent ratings with modest effects in both cases. (b) Agreeableness and Openness decreased for self‐reports and parent ratings, whereas data source differences were found for Conscientiousness (decreased for self‐reports and remained stable for parent ratings), Extraversion (increased for self‐reports and decreased for parent ratings), and Neuroticism (remained stable for self‐reports and decreased for parent ratings). (c) Girls showed a more mature personality overall (self‐reports and parent ratings revealed higher levels of Agreeableness, Conscientiousness, and Openness) and became more extraverted in the middle of adolescence (self‐reports). Personality changes modestly during early adolescence whereby change does not occur in the direction of maturation, and substantial differences exist between parent ratings and self‐reports. 相似文献

Temporal orienting—that is, selective attention to instants in time—has been shown to modulate performance in terms of faster responses in a variety of paradigms. Electrophysiological recordings have shown that temporal orienting modulates neural processing at early, probably perceptual, and late, probably decision- or response-related, stages. Recently, it was shown that the effect of temporal orienting on early auditory brain potentials is independent of the effect of the physical sound feature intensity. This indicates that temporal orienting might not affect stimulus processing by increasing the sensory gain of attended stimuli. In the present study, we investigated whether the independence of temporal-orienting and sound-intensity effects could be replicated behaviorally. Sequences were presented that were either rhythmic, most likely creating temporal expectations, or arrhythmic, presumably not creating such expectations. As hypothesized, the main effects of temporal expectation and sound intensity on reaction times were independent (Experiment 1). The exact pattern of results was replicated with a slightly altered paradigm (Experiment 2) and with a different kind of task (Experiment 3). In sum, these results corroborate the notion that the effect of temporal orienting might not rely on the same processes as the effect of sound intensity does. 相似文献

Personality disorders in juveniles are still a controversially discussed topic. The aim of this paper is to describe the recent trend in personality research in adolescence and to outline perspectives in research and assessment. Recent study results have pointed out that personality disorders in juveniles can be reliably assessed with diagnostic instruments that have been developed for adults. At the same time there is a lack of specific instruments that can represent the characteristics during adolescence and that can differentiate personality disorders from youth crises. As some personality disorder dimensions also describe unstable developmental criteria we will focus separately on this differential diagnosis and meaning of stable versus transient personality characteristics in youth. The prevalence of personality disorders seems to be higher in adolescence than in adulthood. The stability, however, is comparable in adolescence and adulthood. Psychopathy as a subtype of the antisocial personality disorder ?C that can also be assessed in juveniles ?C will be discussed regarding its core and behavioral dimensions as well as primary and secondary subtypes. Furthermore, we discuss forensic issues when assessing personality disorders with respect to criminal responsibility. Overall we can show that more diagnostic longitudinal studies are essential in order to clarify under which conditions personality disorders develop, which factors influence its course and which interventions can change them. 相似文献

Migraine in childhood is a serious health problem with a tendency for chronification. According to the bio-psycho-social model migraine is considered as a disorder generated by multiple factors and requiring an interdisciplinary treatment concept consisting of both medical and psychotherapeutic interventions. Music therapy as a nonverbal, creative arts therapy is especially apt for the treatment of children. A specific treatment concept in music therapy for children with migraine, to be applied within a multidisciplinary framework, and its theoretical background are presented in this article. Music therapy is firmly established within the context of stationary infant psychiatric care. Also, it is presently used as a method of outpatient psychotherapy mainly for children and adolescents. Additionally, music therapy finds frequent use in medical care, special needs education and curative education for children. This article will be limited to the presentation of music therapy as artistic psychotherapy. 相似文献
