The purpose of the present study was to investigate differences in demoralization between those who live in single-person households and those who live in households with others in a random sample of 8,634 urban adults. Responses to the 26-item Psychiatric Epidemiologic Research Interview did not substantiate that adults who live alone are more likely to be demoralized than those who live with others, until age and gender are considered. Men who live alone scored higher on demoralization than men who live with others, yet women who live with others scored higher on demoralization than those who live alone. An interaction for living arrangement and age group on demoralization was also observed. 相似文献

Psychological compensation: a theoretical framework. 总被引:1,自引:0,他引:1
The 2 main objectives of this article are to review a variety of literatures in which the concept of compensation is used and to integrate the results of this review into a general framework of compensation. The review focuses on 4 domains of psychological inquiry: compensation for sensory handicaps, cognitive deficits, interpersonal losses, and brain injury. In the proposed framework, underlying dimensions and 4 basic steps in the progression of compensatory behavior are distinguished. The latter include origins, mechanisms, forms, and consequences. Finally, we describe ways in which researchers in particular domains can benefit from the global, process-oriented framework we propose. For most of the areas of compensation research reviewed, investigators can profit from a consideration of a broader selection of dimensions, additional steps in the process, alternative outcomes, and both objective and subjective assessment procedures. 相似文献

Investigation of the role of 5-hydroxytryptophan (5-HT), which functions as a modulator in the central nervous system, across behavioral contexts suggests that a general principle of transmitter function may be derived that is independent of specific behaviors and specific neural loci. A functional principle of 5-HT action in neural information processing in the central nervous system is proposed. Extremes deviations in 5-HT activity result in biases in information processing that may have direct effects on behavior. Such biases may predispose to pathological conditions such as violent suicide and aggression. 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

At the present, it is unknown how restraint and binge eating/counterregulation are exactly related. Earlier studies on this relationship suffer from two main shortcomings: the studies are all correlational in nature or could not rule out the contribution of confounding variables such as weight loss. The present study investigated whether a break of restraint is a sufficient condition for the occurrence of counterregulation by studying a restrained sample which is not liable to dieting practices and weight loss. The externally imposed restraint on children with regard to eating sweets was broken. However, after breaking their external restraint the children did not counterregulate. It is discussed whether restraint of food intake is really as important for binge eating as it is claimed to be or whether it is merely a consequence or an epiphenomenon of binge eating. 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

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
