In this paper, Bion's different theories on the development of thinking will be introduced: on the one hand, his theory of thoughts as resulting from tolerance for the absence of the object, and on the other hand, dream thoughts and thoughts as resulting from the presence of the object, originally through the mother's containing function. The effects of failures in this development will be discussed; among other things, a hypertrophy of the apparatus of projective identification at the expense of thinking capacities. Briefly, a comparison will be made between a facilitating relation between container and contained and the oscillation between the paranoid-schizoid and depressive position, which Bion describes as a prerequisite for open symbolizing processes. Bion's theories and concepts will be supplemented by Winnicott's theories on the “creative illusion” and the breast/the mother as a “subjective object” as a precondition for the symbolizing capacity that later develops in the “potential space”. Very briefly, a comparison is made between Winnicott's term “the subjective object” and Segal's term “symbolic equation”. Clinical vignettes are interpolated.  相似文献

The field of creativity has largely focused on individual differences in divergent thinking abilities. Recently, contemporary creativity researchers have shown that intelligence and executive functions play an important role in divergent thought, opening new lines of research to examine how higher-order cognitive mechanisms may uniquely contribute to creative thinking. The present study extends previous research on the intelligence and divergent thinking link by systematically examining the relationships among intelligence, working memory, and three fundamental creative processes: associative fluency, divergent thinking, and convergent thinking. Two hundred and sixty five participants were recruited to complete a battery of tasks that assessed a range of elementary to higher-order cognitive processes related to intelligence and creativity. Results provide evidence for an associative basis in two distinct creative processes: divergent thinking and convergent thinking. Findings also supported recent work suggesting that intelligence significantly influences creative thinking. Finally, working memory played a significant role in creative thinking processes. Recasting creativity as a construct consisting of distinct higher-order cognitive processes has important implications for future approaches to studying creativity within an individual differences framework.  相似文献

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex.  相似文献

Type D personality, the combination of negative affectivity (NA) and social inhibition (SI), is an emerging risk factor in cardiovascular disease. This study aimed to examine one possible behavioural mechanism to explain the link between Type D and ill-health. It was hypothesised that Type D personality would predict medication adherence in myocardial infarction (MI) patients. In a prospective study, 192 MI patients (54 females and 138 males) completed measures of Type D personality and provided demographic and medical information 1 week post-MI, and then 131 patients went on to complete a self-report measure of medication adherence 3 months post-MI. It was found that Type D personality predicts adherence to medication, after controlling for demographic and clinical risk factors. Critically, the constituent components of Type D, NA and SI, interact to predict medication adherence, after controlling for the effects of each component separately. Poor adherence to medication may represent one mechanism to explain why Type D cardiac patients experience poor clinical outcome, in comparison to non-Type D patients. Interventions, which target the self-management of medication, may be useful in these high-risk patients.  相似文献

Pressure for ‘positive thinking’ (PT; i.e. focusing on positive thoughts/suppressing negative thoughts to ‘fight’ cancer) burdens cancer patients facing health deterioration. It was determined whether PT exposure enhanced effort, control and responsibility attributions assigned to an individual for his/her cancer trajectory. Within an online blog a hypothetical same-gender person describes a personal cancer experience. 482 participants were assigned to one of six experimental conditions in which we manipulated PT exposure (blogger learns about ‘power of PT’ but does not try it, blogger tries PT, control/no PT) and cancer outcome (successful/unsuccessful treatment). A 3?×?2?×?2 multivariate analysis of covariance (with personal cancer experience covariates) tested PT exposure?×?cancer outcome?×?gender effects on attributions for the blogger's cancer outcome. Results indicate that PT exposure enhanced effort and responsibility attributions assigned to individuals for their cancer outcomes and that responsibility attributions differed as a function of gender. Findings suggest that exposure to the idea of PT may lead to cancer patients being perceived as culpable if they do not recover from the disease.  相似文献

A left-handed metamaterial (a YIG/Ag composite with adjustable negative permittivity and permeability) was prepared by an in situ synthesis process, and its characterisation, microstructure, electrical conductivity, dielectric loss and magnetic properties studied. A negative permittivity behaviour with a Fano-like resonance is ascribed to plasma oscillation of delocalised electrons from silver conducting networks. As the silver content increases, the turbine loss increases, which greatly enhances the electromagnetic wave consumption capacity inside the material and leads to a stronger electromagnetic absorption and shielding performance. The dielectric loss near the percolation threshold is due to the combined effects of polarisation and conduction. The capacitive character is responsible for positive permittivity, and the inductive character leads to negative permittivity. LC resonance results in the Fano-like resonance, leading to the permittivity changing from negative to positive. Gyromagnetic spin rotation, domain wall motion and percolation characteristic of YIG/Ag composites cause frequency dispersion of the permeability. The YIG/Ag composite with double negative characteristics provides prospects for electromagnetic shielding application.  相似文献

Call the thesis that, possibly, there are two times, t1 and t2, such that everything that exists at t2 also exists at t1, but some things that exist at t1 do not exist at t2 Temporal Change. Call the thesis that, possibly, there are two worlds, w and v, such that everything that exists at v also exists at w, but some things that exist at w do not exist at v Modal Difference. I argue that if either Temporal Change or Modal Difference is true, then Orthodox Truthmaker Theory—the theory that every truth requires a necessitating truthmaker—is false.  相似文献

This study investigated whether the perception of intergroup threat, and intergroup emotion, are related to political intolerance. One hundred and twenty three South African undergraduate students (females?=?76%; males?=?24%; White?=?65%; Coloured?=?24%; Indian?=?8%; Chinese?=?2%; mean age =?19.8, SD?=?3.03 years) were randomly assigned to either a heightened (n?=?68) or low intergroup threat condition (n?=?55). Data on intergroup threat, intergroup emotion and political intolerance were collected utilising a questionnaire. T-test effect comparisons including multiple regression analyses were computed to determine effects of intergroup threat and negative intergroup emotion on political intolerance. Results revealed negative intergroup emotion and perceived intergroup threat to predict political intolerance. Negative intergroup emotion mediated the relationship between perceived threat and political intolerance. These findings suggest that intergroup threat may lead to the rise of negative intergroup emotion which in turn creates an environment conducive to the development of political intolerance.  相似文献

This study explored the moderating role of positive affect and negative affect in the link between employees’ career resilience and their career anchors . A convenience sample (N=143) of predominantly black African people (86%) and staff level (80%) employees with more than 10 years of service (60%) participated in the study (mean age: 41 years; men: 52%; women: 48%) . Correlational analysis showed significant associations between the variables . Hierarchical moderated regression analysis indicated low positive affect as a significant moderator of the career resilience-managerial competence career anchor relationship . High negative affect and low negative affect significantly weakened the career resilience-entrepreneurial creativity, career resilience-pure challenge and career resilience-lifestyle relationships . The findings add new insights that may be useful for career development support programmes in the contemporary workplace .  相似文献

This study examines a model relating components of organizational commitment to positive and negative affect through the partial mediation of problem solving coping. The results of a study conducted among a sample of 647 employees from various organizations show that affective commitment relates positively to positive affect and negatively to negative affect, with the relation to positive affect being partially mediated by problem solving coping. Normative commitment was positively related to negative affect. Finally, continuance commitment based on few alternatives was negatively related to positive affect and positively related to negative affect, with the relation to positive affect being partially mediated by a weaker problem solving coping. Continuance commitment based on perceived sacrifice had no effects.  相似文献
