Human participants and recurrent (“connectionist”) neural networks were both trained on a categorization system abstractly similar to natural language systems involving irregular (“strong”) classes and a default class. Both the humans and the networks exhibited staged learning and a generalization pattern reminiscent of the Elsewhere Condition (Kiparsky, 1973). Previous connectionist accounts of related phenomena have often been vague about the nature of the networks’ encoding systems. We analyzed our network using dynamical systems theory, revealing topological and geometric properties that can be directly compared with the mechanisms of non‐connectionist, rule‐based accounts. The results reveal that the networks “contain” structures related to mechanisms posited by rule‐based models, partly vindicating the insights of these models. On the other hand, they support the one mechanism (OM), as opposed to the more than one mechanism (MOM), view of symbolic abstraction by showing how the appearance of MOM behavior can arise emergently from one underlying set of principles. The key new contribution of this study is to show that dynamical systems theory can allow us to explicitly characterize the relationship between the two perspectives in implemented models. 相似文献

Objective : The effect of emotional approach coping (EAC) varies by gender. However, this gender difference has not yet been investigated in cancer survivors. We investigated whether the effects of two kinds of EAC – emotional processing (EP) and emotional expression (EE) – vary by gender and whether EAC has effects above and beyond the effect of other coping strategies. Design : EAC and other coping strategies were assessed at baseline in a sample of 248 young to middle-aged adult (between the age of 22 and 55) cancer survivors. One hundred and sixty-six survivors responded to psychological adjustment one year later. Results : EAC had different relationships with Time 2 adjustment in men and women. Hierarchical regression analyses showed that for men, EE predicted lower intrusive thoughts and, for women, EP was associated with higher positive affect when other coping strategies and EE were controlled. Conclusion : Gender differences held true in cancer survivors, and EAC was effective when other coping strategies were controlled. Further, EE was effective in reducing negative adjustment in men while EP was helpful in promoting positive adjustment in women. 相似文献

Health-risk communications frequently target self-efficacy in order to encourage adaptive responses. Research has also indicated that self-affirmation may be a useful supplementary or alternative intervention technique. This study compared the effects of self-efficacy, self-affirmation and a combination of these techniques for two risk messages. Young British females (N?=?677) read about ultraviolet light and skin cancer or skin ageing (‘photoageing’) and were randomly assigned to a single intervention (self-affirmation/self-efficacy), the combined intervention or no intervention. The efficacy intervention led to greater message acceptance and perceived risk in both the cancer and photoageing conditions, while the only main effect of self-affirmation was on acceptance of the photoageing message. However, self-affirmation moderated the effect of efficacy information. For photoageing messages, efficacy information was associated with greater message acceptance only amongst self-affirmed participants, but the opposite occurred for skin cancer messages. Although these findings should be interpreted cautiously, they imply that health promoters should select efficacy information if only one intervention is used but that self-affirmation can influence responsiveness to efficacy interventions for particular messages. 相似文献

Language delay is a frequent antecedent of literacy problems, and both may be linked to phonological impairment. Studies on developmental dyslexia have led to contradictory results due to the heterogeneity of the pathological samples. The present study investigated whether Italian children with dyslexia showed selective phonological processing deficits or more widespread linguistic impairment and whether these deficits were associated with previous language delay. We chose 46 children with specific reading deficits and divided them into two groups based on whether they had language delay (LD) or not (NoLD). LD and NoLD children showed similar, severe deficits in reading and spelling decoding, but only LD children showed a moderate impairment in reading comprehension. LD children were more impaired in phonological working memory and phonological fluency, as well as in semantic fluency, grammatical comprehension, and verbal IQ. These findings indicate the presence of a moderate but widespread linguistic deficit (not limited to phonological processing) in a subset of dyslexic children with previous language delay that does not generalize to all children with reading difficulties. 相似文献

Competition strongly affects individual effort and performance for both individuals and groups. Especially in work settings, these effort gains might come at the cost of individual well‐being. The present study tested whether competition increases both effort (as indicated by task performance) and stress (in terms of cardiovascular reactivity and affective response), and whether this effect is further qualified by the type of competition (interindividual vs. intergroup), using a cognitive computer‐based task and a 2 (Group: Yes, No) × 2 (Competition: Yes, No) × 2 (Gender) factorial design (N= 147). All participants either worked as a representative of a group or as an individual, and were offered performance‐related incentives distributed in a lottery. In the competition conditions, participants were informed that they competed with someone else, and that only the winning person/team would take part in the lottery. Consistent with expectations, competition increased both individual effort and cardiovascular reactivity compared to non‐competitive work. Moreover, for female participants, intergroup competition triggered increased effort and more positive affect than interindividual competition. Aside from documenting costly side‐effects of competition in terms of stress, this study provides evidence for a stress‐related explanation of effort gains during intergroup competition as compared to interindividual competition. 相似文献

We report on a volunteer programme for undergraduate psychology students, as a prospective career pathway into the inpatient mental health context. Data on motives for joining the programme, as well as their expectations and career plans were collected from 56 students (mainly under 25 years of age; approximately 80% females) in a volunteer placement within an inpatient mental health setting. About 89.3% of the volunteers reported being on the programme to enhance their applications for postgraduate training prospects in the same field. Only 10.7% were motivated primarily by the desire to help mentally ill patients. Over three-quarters planned to pursue postgraduate training in clinical psychology. 相似文献

This study validated the psychometric structure of the Connor-Davidson Resilience Scale (CD-RISC; Connor & Davidson, 2003) in a sample of 227 homeless youth in Ghana. Principal Component Analysis (PCA) with Varimax rotation was used to extract factor structures. About 62% of the total variance was accounted for by a three-factor structure: personal competence and tenacity, optimism and achievement motivation. Evidence of the external validity of scales was supported by the positive correlation between resilience and perceived social support scores. The CD-RISC appears to yield scores reliable for assessing resilience among homeless youth in a developing world context. 相似文献

The majority of Holocaust survivors never speak publicly about their experiences, but those who do tend to find themselves at the centre of commemorative work in their communities. As Holocaust scholars, Holocaust education institutions, and members of the general public become increasingly interested in how to ethically universalize the lessons of the Holocaust, the public Holocaust survivor's role has broadened. It is no longer enough to recount one's own experience; survivors are expected to speak to current human rights abuses and genocides.In Montreal, Canada, a city which once claimed the third largest survivor population in the world, public survivors do a great deal of work. They give testimony in schools and at commemorative events, organize book clubs, write plays, direct films, teach, act as museum docents, and assume roles as community spokespeople. Given their dedication to this work, and a push to get them to speak beyond their personal experiences, we argue that there is a major shift taking place: the act of giving public Holocaust testimony is being professionalized. This professionalization raises unique questions about how people who lived through the Holocaust conceptualize themselves and their identities as survivors. By treating testimony as professional work, survivors contemplate, on a daily basis and in an applied manner, their stances on big questions regarding hierarchies of suffering, comparability, the connection between the personal and the political, blame and forgiveness, as well as many other relevant themes that are central to Holocaust and memory scholarship. All of this plays out in their testimonies. 相似文献

Abstract This paper describes how a counsellor in education has to take on and respond to a number of transferences in the clinical work in addition to holding onto a number of centres within the institution and personally. It takes a close look at one student presentation and speaks to the quality of the emotional and psychological impact on the counsellor. It argues for the need to be both thoughtfully containing and thoughtfully penetrating in the clinical work despite the bombardment of conscious and unconscious material. Over all, the paper states how important it is for the counsellor to stay in touch with his/her own feelings, thereby effectively maintaining the depressive position, though this is painful given the current predominance of suicide and serious suicidal intentions among adolescents and young adults. 相似文献

Abstract This paper explores the relationship between our attempts to define the aims of analysis and the acceptance of probability in New Physics. It draws attention to the influence of physicists on both Jung and Bion, which is well documented. It presents an argument for process-based aims rather than the recognition of innate knowledge as an aim. Two processes from different traditions (Jungian and Kleinian) are suggested as central to the aims of analysis: containment and coniunctio. The coniunctio/disiunctio axis in Jung's writing is paralleled with the axis PS<->D of the post-Kleinians. Clinical material is presented supporting the necessity of differential aims and illustrating development/stasis along this axis. A case is made for analysis to embrace the reality of uncertainty and to work with the psychic obstacles in patients, and in analysts, that result from coming to terms with probability. 相似文献
