The author explores Freud's concept of narcissism, as well as other discussions of narcissism in the psychoanalytic literature. He introduces the dual conception of positive narcissism and negative narcissism, illustrated by two clinical vignettes. Subsequent discussion elaborates on these two types of narcissism, and also addresses life narcissism, death narcissism, and primary narcissism. The latter is considered in light of the influence of infant observational research on the prevailing view of this concept and the misunderstandings that arise from that approach. 相似文献

Recent studies show that the preparation of an action can interfere with the concurrent detection and identification of objects that share features with this action, a phenomenon termed blindness to response-compatible stimuli. In order to account for the blindness effect, an integration mechanism for response features similar to the one suggested for object features has been proposed. In the present article, we propose an alternative explanation, namely an action-effect inhibition mechanism. This mechanism was demonstrated in two versions of a dual-task experiment using a primary stop-signal task. The results showed that when the primary response was withheld (signal-inhibit trials), this resulted in lower identification rates for compatible secondary task stimuli. On the other hand, we did not find any evidence for a blindness effect when the primary response was executed (no-signal trials). Additionally we found that identification rates depended on the time course of the inhibition process as estimated from our data. Consequently, the blindness effect seems to result from the requirement to inhibit the response, perhaps even if only temporary. 相似文献

In a comparison of 2 treatments, if outcome scores are denoted by X in 1 condition and by Y in the other, stochastic equality is defined as P(X < Y) = P(X > Y). Tests of stochastic equality can be affected by characteristics of the distributions being compared, such as heterogeneity of variance. Thus, various robust tests of stochastic equality have been proposed and are evaluated here using a Monte Carlo study with sample sizes ranging from 10 to 30. Three robust tests are identified that perform well in Type I error rates and power except when extremely skewed data co-occur with very small n. When tests of stochastic equality might be preferred to tests of means is also considered. 相似文献

Twenty-three empirical studies published between 1978 and 2000 on nonclinical children raised by lesbian mothers or gay fathers were reviewed (one Belgian/Dutch, one Danish, three British, and 18 North American). Twenty reported on offspring of lesbian mothers, and three on offspring of gay fathers. The studies encompassed a total of 615 offspring (age range 1.5-44 years) of lesbian mothers or gay fathers and 387 controls, who were assessed by psychological tests, questionnaires or interviews. Seven types of outcomes were found to be typical: emotional functioning, sexual preference, stigmatization, gender role behavior, behavioral adjustment, gender identity, and cognitive functioning. Children raised by lesbian mothers or gay fathers did not systematically differ from other children on any of the outcomes. The studies indicate that children raised by lesbian women do not experience adverse outcomes compared with other children. The same holds for children raised by gay men, but more studies should be done. 相似文献

The present study investigated the relationship between Epstein’s (1998, Constructive thinking: The key to emotional intelligence. London: Praeger publisher.) components of constructive thinking and burnout as experienced by a sample of Dutch secondary
school teachers. A postal questionnaire was sent to teachers from randomly selected secondary schools. The response rate was
54.1% (N=433). Four components of constructive thinking significantly contributed to the explained variance in emotional exhaustion
(17%), depersonalization (21%), and personal accomplishment (20%). The results of the study suggest that secondary school
teachers’ maladaptive thinking processes prevent them from rational thinking during their work, which significantly contributes
to the onset of burnout. Burnout intervention programs for teachers are likely to be more effective when the participator’s
maladaptive thinking system is taken into consideration. This stems from the idea that personality factors are a probably
easier point of departure to tackle burnout symptoms than organizational factors. 相似文献

The Observer 3.0 (Noldus, 1991) was used as the base for a time-saving fine analysis of animal behavior. A PC controlled a shuttlebox and a shuttlebox control unit. Learning behavior was recorded on videotapes by an S-VHS camcorder with vertical interval time code (VITC), which was used to generate an observational data file (ODF). The observational system was enhanced by automatically recorded status signals from the PC as event markers on the soundtrack of the videotape. These signals were used to subdivide a training session into numbered trials during generation of the ODF. They were later used for a PC-aided fine analysis of behavioral events, such as attention responses (AR) and orienting responses (OR) during shuttlebox learning. In this way, a large number of both automatically inserted PC event markers and manually inserted, key-defined behavioral events were registered and analyzed effectively in a semiautomatic fashion. The system is illustrated with an analysis of shuttlebox avoidance data from gerbils (Meriones unguiculatus). 相似文献

The influence of problem features and individual differences on strategic performance in simple arithmetic 总被引:2,自引:0,他引:2
The present study examined the influence of features differing across problems (problem size and operation) and across individuals (gender, amount of daily arithmetic practice, calculator use, and arithmetic skill) on simple arithmetic performance. Regression analyses were used to investigate the role of these variables in both strategy selection and strategy efficiency. Results show that more skilled and highly practiced students used memory retrieval more often and executed their strategies more efficiently than did less skilled and practiced students. Furthermore, calculator use correlated with both retrieval and procedural strategy efficiency but not with strategy selection. Only very small associations with gender were observed, with boys retrieving slightly faster than girls. Implications of the present findings for models of mental arithmetic are discussed. 相似文献

The present study proposes a new executive task, the one-back choice reaction time (RT) task, and implements the selective interference paradigm to estimate the executive demands of the processing components involved in this task. Based on the similarities between a one-back choice RT task and the n-back updating task, it was hypothesized that one-back delaying of a choice reaction involves executive control. In three experiments, framed within Baddeley's (1986) working-memory model, a one-back choice RT task, a choice RT task, articulatory suppression, and matrix tapping were performed concurrently with primary tasks involving verbal, visuospatial, and executive processing. The results demonstrate that one-back delaying of a choice reaction interferes with tasks requiring executive control, while the potential interference at the level of the verbal or visuospatial working memory slave systems remains minimal. 相似文献

The current study tested the development of working memory involvement in children's arithmetic strategy selection and strategy efficiency. To this end, an experiment in which the dual-task method and the choice/no-choice method were combined was administered to 10- to 12-year-olds. Working memory was needed in retrieval, transformation, and counting strategies, but the ratio between available working memory resources and arithmetic task demands changed across development. More frequent retrieval use, more efficient memory retrieval, and more efficient counting processes reduced the working memory requirements. Strategy efficiency and strategy selection were also modified by individual differences such as processing speed, arithmetic skill, gender, and math anxiety. Short-term memory capacity, in contrast, was not related to children's strategy selection or strategy efficiency. 相似文献

When analyzing genetic data, Structural Equations Modeling (SEM) provides a straightforward methodology to decompose phenotypic variance using a model-based approach. Furthermore, several models can be easily implemented, tested, and compared using SEM, allowing the researcher to obtain valuable information about the sources of variability. This methodology is briefly described and applied to re-analyze a Spanish set of IQ data using the biometric ACE model. In summary, we report heritability estimates that are consistent with those of previous studies and support substantial genetic contribution to phenotypic IQ; around 40% of the variance can be attributable to it. With regard to the environmental contribution, shared environment accounts for 50% of the variance, and non-shared environment accounts for the remaining 10%. These results are discussed in the text. 相似文献
