Among factors favoring the addictive behaviors, some specific family processes are often identified in eating disorders and dependences with psychoactive substances. Different models of systemic orientation described the familial disturbances involved in the addictive pathologies emphasizing either the emotional interaction and the processes of differentiation family, either the structure and the level of family cohesion. This article proposes a critical review of the systemic literature on the familial disturbances involved in the families of adolescents with eating disorders or with a substance-dependence. The systemic models (Bowen, Minuchin) are reference values in the understanding of family processes and therapy with families. The observations of these family processes have been confronted to empirical researches integrating different epistemological levels and different methods. The empirical results are heterogenous concerning the different forms of family functioning associated with these addictive pathologies. The empirical studies support the hypothesis of a family dysfunctioning in the different addictive behaviors and demonstrate the relationship between the severity of familial disorders and the severity of the addictive disorders. However, the family configuration described by the typological models is rarely found complete or with a similar intensity between the families. The studies support the hypothesis of an emotional distance in the family interactions and a lack of parental care which could correspond to factors of chronicity or vulnerability. Comparing the family characteristics of these two types of addictive behaviors, the literature supports the existence of (1) some specific family characteristics according to the type of addictive behavior (in particular the conflict avoidance which appears specifically in anorexic families) (2) some similar family patterns of interactions between the members of addictive families in particular the representation of a low family cohesion, an intergenerational enmeschment and a high level of control. These family patterns suggest rather to a dimensional approach of the family characterized by different protective or risk factors. We suggest that these family patterns could constitute, according to their importance (intensity and frequence), a family risk factor of development or aggravation of the addictive behaviors. 相似文献

This study of social representations aims at identifying the process involved in the responses produced with a substitution technique. Two alternative hypotheses are discussed: one that considers that substitution induces social comparison (Chokier and Moliner, 2006), the other suggesting that this technique leads to a reduction of normative pressures (Guimelli, 1998). In the research presented here, we studied the social representations of Drug addicts (in the tolerance towards the use of cannabis) and of Unemployed people, in order to compare the results with those obtained by Chokier and Moliner (2006) about security. With a specific population of students, these objects allowed us to manipulate two levels of distance to the object of representation. Concerning the technique of substitution, three levels of distance to the reference group (French people in general, Young people, Students) were combined into questionnaires with four types of instructions: standard, substitution, pro- and counter-normative. The PCA highlights a Guttman effect, which indicating that the responses produced with standard instruction are less normative than the responses produced with the substitution instruction to Young people. These results invalidate an explanation in terms of effect Primus Inter Pares. Globally, the results mainly show that the more the distance to the object is low and the distance to the reference group is high, the more the responses produce in substitution are seen as pro-normative and near from those produced with standard instruction. More specifically, we identified a number of inconsistencies with regard to what one could expect from an explanation of the phenomena in terms of personal versus social identity. As regards the representation of Unemployed people, the more the participants are closed to the reference group, the more the responses produced with an instruction of auto-valorization (pro-normative) are closed to those produced in substitution. However, on one hand, this result is observed only with the representation of Unemployed people, and, on the other hand, a social comparison explanation would suppose that the participants perceived the group of French people in general as homogeneous and identified themselves to this group at the same level than to the two other reference groups, which is unlikely. Finally, these results lead us to conclude that the substitution does not induce social comparison (Chokier and Moliner, 2006), but more probably reduction of normative pressures (Guimelli, 1998). It thus suggests that the study of masking effects through a substitution technique should take into account two parameters: distance to the object and distance to the reference group. 相似文献

Background
Tourette syndrome (TS) is characterized by dysfunctional connectivity between prefrontal cortex and sub-cortical structures, and altered meso-cortical and/or meso-striatal dopamine release. Since time processing is also regulated by fronto-striatal circuits and modulated by dopaminergic transmission, we hypothesized that time processing is abnormal in TS.Methods
We compared time processing abilities between nine children with TS-only (i.e. without major psychiatric comorbidities) and 10 age-matched healthy children, employing a time reproduction task in which subjects actively reproduce different temporal intervals, and a time comparison task in which subjects judge whether a test interval is longer or shorter than a reference interval. IQ, sustained and divided attention, and working memory were assessed in both groups using the Leiter International Performance Scale-Revised, and the Digit Span sub-test of the WISC-R.Results
Children with TS-only reproduced in an overestimated fashion over-second, but not sub-second, time intervals. The precision of over-second intervals reproduction correlated with tic severity, in that the lower the tic severity, the closer the reproduction of over-second time intervals to their real duration. Time reproduction performance did not significantly correlate with IQ, attention and working memory measures in both groups. No differences between groups were documented in the time comparison task.Conclusions
The improvement of time processing in children with TS-only seems specific for the over-second range of intervals, consistent with an enhancement in the ‘cognitively controlled’ timing system, which mainly processes longer duration intervals, and depends upon dysfunctional connectivity between the basal ganglia and the dorso-lateral prefrontal cortex. The absence of between-group differences on time comparison, moreover, suggests that TS patients manifest a selective improvement of ‘motor’ timing abilities, rather than of perceptual time abilities. Our data also support an enhancement of cognitive control processes in TS children, probably facilitated by effortful tic suppression. 相似文献904.
The neuropsychological literature on the processing of emotions in Parkinson’s disease (PD) reveals conflicting evidence about the role of the basal ganglia in the recognition of facial emotions. Hence, the present study had two objectives. One was to determine the extent to which the visual processing of emotions and objects differs in PD. The other was to assess the impact of cognitive load on the processing of these types of information. Thirty-one patients with idiopathic PD (IPD) under dopamine replacement therapy (DRT) were compared to 30 control subjects on emotion and object recognition tasks. Recognition of objects was more accurate and faster than recognition of facial expressions of emotion, for both groups of subjects. In a second experiment using an N-back procedure with the same stimuli—a more demanding task with a higher cognitive load—patients with IPD were as accurate as control subjects in detecting the correct sequential presentation of stimuli, but were much slower in their decision responses. This indicates that IPD patients under DRT are not impaired in encoding emotion or object information, but that they have difficulty with the processing demands of the N-back task. Thus, patients with IPD appear to be more sensitive to cognitive load than to type of information, whether facial emotions or objects. In this perspective, one must consider that a deafferented dopaminergic system has problems processing more complex information before one can posit the existence of deficits affecting a specific type of information. 相似文献

Impairment of the Self has been described in frontal–temporal dementia but little research has been carried out in patients with Alzheimer’s disease (AD).
Objective
The aim of this study was to explore changes in the self in patients with AD.Method
Forty-seven patients with mild to moderate AD were examined using a semi-structured scale designed to assess the self-concept along three dimensions, namely, the Material Self, the Social Self and the Spiritual Self.Results
The majority of patients (43 out of 47) presented impairment of at least one dimension of the Self. When only one dimension was affected, it was always the Social Self. The severity of impairment of the Self was correlated to the impairment of the semantic autobiographical memory and apathy.Conclusion
The Self is impaired in AD and the Social Self dimension appears to be more vulnerable in AD than other dimensions. 相似文献907.

This article shows that the Rhodian model of metatheory can be successfully applied to nonformal systems of a methodological rather than an axiological nature if the demands of the model are satisfied. This requires that we take into account the possible variations of Rhodian models of argumentation and choose the most effective of them. Plato's model of meta‐argumentation is only applicable to fields of argumentation that are completely formalized and could be presented as whole general theories. 相似文献

The focus of this study was on revising the Inventory of Children's Activities–Revised (ICA-R; Tracey & Ward, 1998) to enhance its psychometric properties while minimizing gender differences in scale scores. The original 30 ICA-R items and an additional 30 items were administered to 70,280 fifth-eighth grades students. The original scoring was compared to a revised scoring method based solely on the empirically best items and a scoring method balancing empirical scoring with minimizing gender differences. All three item sets (original, empirical, and combined empirical/gender balancing) resulted in strong internal consistency estimates and adequate fit to the circular structure, yet the combined empirical/gender method had much lower gender differences especially for the scales measuring Investigative and Social interests. The implications of using the revised scale with children is discussed. 相似文献

Richard Foley has presented a puzzle purporting to show that all attempts in trying to find a sufficient condition of rationality are doomed. The puzzle rests on two plausible assumptions. The first is a level-connecting principle: if one rationally believes that one's belief that p is irrational, then one's belief that p is irrational. The second is a claim about a structural feature shared by all promising sufficient conditions of rationality: for any such condition, it is possible that one's belief satisfies it and yet one rationally believes that it doesn’t. With the two assumptions, Foley argues that a sufficient condition of rationality is impossible. I explain how exactly the puzzle goes and I try to offer a solution. If my solution works, all theorists of rationality who accept certain level-connecting principles need to add an extra condition to their favourite rationality-making condition. 相似文献

Barreto's paper, ‘Requiem for analytical psychology’ utilized Jung's dreams and visions to argue for the obsolescence of Jungian psychology. Its thesis rested upon the theoretical assumptions of Giegerich's psychology as a Discipline of Interiority, which he and Giegerich claim are themselves based in Jung's psychology. Here I argue that that claim is misplaced because it depends upon a fundamental misunderstanding of the nature of Jung's psychological project. I shall further argue that Giegerich's arguments for a Jungian basis to his psychology rely upon misreadings and decontextualisations of Jung's original texts. Finally, I shall attempt to draw attention to the weaknesses and contradictions involved in Barreto's interpretations of Jung's dreams and visions. 相似文献
