This study discusses a case of aphasia after dominant thalamic lesion, a hemorrhagic infarction. Unlike other such cases, both repeated standardized assessment and postmortem verification were available. The patient was assessed at 3 weeks and again at 9 weeks postonset. The aphasia demonstrated the syndrome common to dominant thalamic hemorrhage: fluent but paraphasic output sometimes deteriorating to jargon, comprehension less impaired than this type of output usually indicates, and the least impairment in repetition. As sometimes reported in previous cases, semantic paraphasias were more common than phonemic paraphasias. The lesion was located in the dorsal aspect of the lateral nucleus, but it extended into the pulvinar, including the anterior superior lateral aspect which has been implicated in language by previous studies. Thus, data from this case are consistent with an involvement of the dominant pulvinar in language and suggest that this role involves the semantic aspects of language. 相似文献

Dethier (1957) described an aspect of food-search behavior in Phormia regina as the blow fly dance. A hungry fly walks in relatively straight lines with its proboscis retracted until it encounters food (sucrose). After ingesting even a small amount of sucrose, the fly begins making frequent, tight turns, flexes its front tarsi to bring more chemosensory hairs into contact with the substrate and repeatedly extends and retracts its proboscis. Like the central excitatory state (CES), which causes an increase in proboscis extensions to water when a fly is stimulated with sucrose, the dance lasts longer in hungrier flies or with higher sucrose concentrations. It was considered that dance behavior might be an ethologically relevant manifestation of CES. In order to test this hypothesis, dance duration in lines selected for high- and low-CES levels was measured. As predicted, flies from the high-CES line danced longer than those from the low-CES line, and the CES-dance correlation in individual flies was high. This phenotypic correlation disappeared in the F2 generation of a cross between the high- and low-CES lines, a result indicating that the observed variations in CES and dance duration were not caused by the same set of genes. Further characterization of the underlying genetic system showed that several linked autosomal genes with digenic epistatic interactions and a complex pattern of maternal inheritance were responsible for the difference in dance durations between the high- and low-CES lines. 相似文献

It has been reported that depression and anxiety have overlapping symptoms and are conceptually interrelated. One of the most
prominent theoretical developments that explain this association is Clark and Watson’s tripartite model (Journal of Abnormal
Psychology, 100:316–336, 1991) that posits these two disorders and negative emotions share a latent component of negative affect (NA). The current study
had two aims, (a) to compare a tripartite factor structure against competing models by Confirmatory Factor Analysis (CFA)
of the Depression Anxiety and Stress Scales (DASS-21) (Lovibond and Lovibond 1995), and (b) explore the psychometric properties of the DASS-21. The DASS-21 was completed by a representative sample of 4039
young Australians, aged 12–18 years, as part of the South Australian Youth Mental Health Survey (SAYMHS), South Australia,
Australia. The best fitting model for the data consisted of anhedonic depression, physiological hyperarousal, and general
NA. The psychometric properties of the DASS-21 were excellent with a stable and interpretable factor structure and good internal
consistency. The results of the current study suggest that the theoretical tripartite structure of depression and anxiety
is robust and applicable among Australian youth. The diagnostic, clinical and theoretical implications of these findings are
discussed. 相似文献

For Duns Scotus, facts about moral psychology are ultimately reducible to facts about ontology. The created agent has a soul which includes as formal “parts” the intellect and will; the intellect and will, of course, are the seat of qualities (e.g. thoughts and volitions, respectively) and habits (e.g. virtues) that are related to one another in various ways. One of these ways is the conformity relation. From a metaphysical base of categorical being – whether Substance, Quality/Habit, or Relation – Scotus constructs an ethical theory which complements, though in some interesting ways departs from, the Aristotelian tradition of which he is a part. In this essay, our aim is twofold: first, to reconstruct the ontological status of virtue within Scotus's overall metaphysical framework. Second, we attend to the ways in which this metaphysic of virtue places constraints on how one is to understand the conformity relation that, according to Scotus, must exist between an agent's will and right reason whenever a morally good action results. 相似文献

How to draw the line between depression‐as‐disorder and non‐pathological depressive symptoms continues to be a contested issue in psychiatry. Relatively few philosophers have waded into this debate, but the tools of philosophical analysis are quite relevant to it. In this paper, I defend a particular answer to this question, the Contextual approach. On this view, depression is a disorder if and only if it is a disproportionate response to a justifying cause or else is unconnected to any justifying cause. I present four objections to this approach and then defend it from them. Along the way, I explain why it matters whether we get this question right. 相似文献
