Recent evidence suggests that there is a relationship between depression and immunity. On the basis of these studies, it has been argued that depressed mood may increase susceptibility to disease by means of aberrations occurring within the immune system. Empirical research investigating the relationship between depression and immunity is reviewed here. Studies examining both clinical and nonclinical manifestations of depression are discussed and evaluated. This review reveals that indexes of immunocompetence are lower among people exhibiting depressive symptomology and suggests that immune alterations may be more related to dysphoric mood than to specific situations or events. Alternative hypotheses accounting for links between depressed affect and altered immune states are provided, and suggestions for future research are offered. 相似文献

Functional models of face recognition and speech production have developed separately. However, naming a familiar face is, of course, an act of speech production. In this paper we propose a revision of Bruce and Young's (1986) model of face processing, which incorporates two features of Levelt's (1989) model of speech production. In particular, the proposed model includes two stages of lexical access for names and monitoring of face naming based on a "perceptual loop". Two predictions were derived from the perceptual loop hypothesis of speech monitoring: (1) naming errors in which a (correct) rare surname is erroneously replaced by a common surname should occur more frequently than the reverse substitution (the error asymmetry effect); (2) naming errors in which a common surname is articulated are more likely to be repaired than errors which result in articulation of a rare surname (the error-repairing effect). Both predictions were supported by an analysis of face naming errors in a laboratory face naming task. In a further experiment we considered the possibility that the effects of surname frequency observed in face naming errors could be explained by the frequency sensitivity of lexical access in speech production. However, no effect of the frequency of the surname of the faces used in the previous experiment was found on face naming latencies. Therefore, it is concluded that the perceptual loop hypothesis provides the more parsimonious account of the entire pattern of the results. 相似文献

In this paper we address the question how in language production conceptual structures are mapped onto lexical items. First we describe the lexical system in a fairly abstract way. Such a system consists of, among other things, a fixed set of basic lexical entries characterized by four groups of information: phonetic form, grammatical features, argument structure, and semantic form. A crucial assumption of the paper is that the meaning in a lexical entry has a complex internal structure composed of more primitive elements (decomposition). Some aspects of argument structure and semantic form and their interaction are discussed with respect to the issue of synonymy. We propose two different mappings involved in lexical access. One maps conceptual structures to semantic forms, and the other maps semantic forms to conceptual structures. Both mappings are context dependent and are many-to-many mappings. We present an elaboration of Levelt's (1989) model in which these processes interact with the grammatical encoder and the mental lexicon. Then we address the consequences of decomposition for processing models, especially the nature of the input of lexical access and the time course. Processing models that use the activation metaphor may have difficulties accounting for certain phenomena where a certain lemma triggers not one, but two or more word forms that have to be produced with other word forms in between. 相似文献

Picture naming. 总被引:11,自引:0,他引:11
W R Glaser 《Cognition》1992,42(1-3):61-105
Picture naming has become an important experimental paradigm in cognitive psychology. To name a picture can be considered an elementary process in the use of language. Thus, its chronometric analysis elucidates cognitive structures and processes that underlie speaking. Essentially, these analyses compare picture naming with reading, picture categorizing, and word categorizing. Furthermore, techniques of double stimulation such as the paradigms of priming and of Stroop-like interference are used. In this article, recent results obtained with these methods are reviewed and discussed with regard to five hypotheses about the cognitive structures that are involved in picture naming. Beside the older hypotheses of internal coding systems with only verbal or only pictorial format, the hypotheses of an internal dual code with a pictorial and a verbal component, of a common abstract code with logogen and pictogen subsystems, and the so-called lexical hypothesis are discussed. The latter postulates two main components: an abstract semantic memory which, nevertheless, also subserves picture processing, and a lexicon that carries out the huge amount of word processing without semantic interpretation that is necessary in hearing, reading, speaking and writing. 相似文献

The need for efficient and practical assessment techniques of the multidimensional nature of chronic pain remains paramount in clinical settings. Visual analogue scales (VASs) and simple behavioral observation methods have been proposed as efficient, reliable, and valid measures of the subjective (sensory and affective) and overt behavioral aspects of the pain experience. The relationships among VASs and the UAB Pain Behavior Scale were examined among 48 chronic pain patients. Ratings of overt behavior were significantly related to both the VAS sensory and VAS affective ratings. Regression analysis indicated that the VAS scores accounted for significant amount of the variance (27.7%) in UAB scores. Moreover, the affective dimension of self-reported pain tended to be more strongly related to the visible manifestations of pain than were ratings of pain intensity. 相似文献

Recent studies, mostly performed on bulimic outpatients, did not find consistent predictors of treatment outcome in bulimia nervosa. This is the first study to investigate anamnestic and clinical factors predictive of the short-term outcome of hospital treatment in 31 female bulimia nervosa patients with a mean age of 22.9 yr. Treatment outcome was assessed by several self-rating instruments measuring different features of the specific and unspecific psychopathology of bulimia nervosa. The most relevant predictors of the outcome of the 8-week hospital treatment were duration of previous inpatient treatments for bulimia, the intensity of anorexic tendency and the pretreatment level of depression. The majority of predictors tested did not show a strong relationship to treatment outcome. The findings are discussed in relation to results of other studies as well as to possible implications for treatment and research. 相似文献

Clinical material is presented leading to a discussion of beating fantasies which varies from Freud's model. Analysis shows that the fantasied role girls assign to mother as the punisher in the oedipal drama is equivalent to the fantasied role boys ascribe to father as castrator. For both sexes, castration anxiety spurs the internalization of parental prohibitions, the repression of oedipal wishes, and the subsequent structuralization of the superego. Mother establishes the "oedipal law" for the girl analogously to father's doing the same for the boy. The role that such fantasies play in the formation of the female superego is examined. 相似文献

The debt of neuropsychology to the epilepsies. 总被引:3,自引:0,他引:3
R A Novelly 《The American psychologist》1992,47(9):1126-1129
Both neuropsychology and psychology in general have been enhanced markedly by brain-behavior models derived from the study of the epilepsies. A significant body of neuropsychological concepts originated or were confirmed through epilepsy-based treatment and research. These concepts include the peri-Rolandic homunculus, the role of the hippocampal-temporal lobe complex in cognitive memory, hemisphere plasticity for speech in childhood, the intracarotid amytal procedure for determining hemisphere memory patency, and hemisphere-based models of cognition confirmed through human commissurotomy. Personality and social-emotional research in epilepsy are additional areas in which new conceptual models grounded in psychological science can both repay our debt to the epilepsies and provide much needed psychological research and treatment. 相似文献
