ABSTRACT

This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research.  相似文献

ABSTRACT

Artistic creation often involves the use of mental images. This investigation examined the influence of training in artistic skills on mental imaging capacity in a sample of 126 subjects aged between 18 and 23 years. First- and 5th-year fine arts students were compared with regard to their performance in 2 imaging capacity tests (the Visual Elaboration Scale and the Vividness of Visual Imagery Test) and 3 tests of drawing involving spatial representation, transformation of spatial relations, and memory. The students who had undergone a longer period of artistic training performed significantly better on all 5 tests, and all drawing tasks scores correlated with each other. These results indicate that artistic training may enhance imaging capacity.  相似文献

The aim of this study was to examine the associations of control and vividness of mental imagery on performance in several components of in-depth drawing in a sample of fine arts undergraduates. The sample consisted of 56 second-year undergraduates (44 women and 12 men, mean age = 21.18 years) from the Fine Arts Faculty of Vigo University, Pontevedra, Spain. Participants were required to undertake a plastic art assignment focusing on the pictorial representation of space. Participants scoring high on the image control test obtained higher scores on the spatial analysis and in the formal construction of a work than participants with poor image control. Further research involving spatial image performance tests and mental image rotation tests is proposed.  相似文献

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.  相似文献

Abstract

This study addressed the question whether the affect evoked by social comparisons and individual differences in social comparison orientation (SCO) may predict the development of burnout over a period of one year. The participants were 93 nurses (25 males and 68 females) who filled out a questionnaire twice, with an interval of about one year. Comparisons with others performing better than oneself (upward comparisons) were reported to occur more often, to evoke more positive affect, and to invoke less negative affect than comparisons with others performing worse than oneself (downward comparisons). Those who responded at Time 1 (T1) with more positive affect to upward comparison and with less negative affect to downward comparisons, showed a decrease in burnout at Time 2 (T2). In addition, those who responded with relatively more negative affect to upward comparisons at T1, showed an increase in burnout at T2, but only when they were high in SCO. It is concluded that in this population upward comparisons were more prevalent than, and evoked more favorable responses than, downward comparisons. The most important conclusion is that the affect evoked by social comparisons may predict future changes in burnout.  相似文献

The study was designed to assess the influence of child’s personality and perception of parental relationship on children’s optimal experiences. We proposed functional and dysfunctional models to analyze the increase or the decrease of the children’s flow experience. The sample of this study included 909 middle class children, aged 9–12 (M = 11.02, SD = 1.08), both sexes, from Argentina. When we analysed the psychological factors that could be related to the flow state in childhood, we found out that the child’s perception of a functional parental relationship, in which there is either acceptance or moderate control, indirectly affects the flow experience, through child’s personality—extraversion, openness to experience, and conscientiousness. Functional personality traits have an important positive effect on optimal experience when they are considered as a unit. In the dysfunctional model of flow, the results showed that the child’s perception of parental pathological control had an important positive effect on neuroticism and –through this—a negative effect on flow. The child’s perception of parental negligence did not have a significant effect on neuroticism; however, neuroticism still maintained its negative effect on flow.  相似文献

In contextual conditioning, a complex pattern of information is processed to associate the characteristics of a particular place with incentive or aversive reinforcements. This type of learning has been widely studied in mammals, but studies of other taxa are scarce. The context-signal memory (CSM) paradigm of the crab Chasmagnathus has been extensively used as a model of learning and memory. Although initially interpreted as habituation, some characteristics of contextual conditioning have been described. However, no anticipatory response has been detected for animals exposed to the training context. Thus, CSM could be interpreted either as an associative habituation or as contextual conditioning that occurs without a context-evoked anticipatory response. Here, we describe a training protocol developed for contextual Pavlovian conditioning (CPC). For each training trial, the context (conditioned stimulus, CS) was discretely presented and finished together with the unconditioned stimulus (US). In agreement with the CSM paradigm, a robust freezing response was acquired during the 15 training trials, and clear retention was found when tested with the US presentation after short (2 and 4 h) and long (1–4 days) delays. This CPC memory showed forward but not simultaneous presentation conditioning and was context specific and protein synthesis dependent. Additionally, a weak CPC memory was enhanced during consolidation. One day after training, CPC was extinguished by repeated CS presentation, while one presentation induced a memory labilisation–reconsolidation process. Finally, we found an anticipatory conditioned response (CR) during the CS presentation for both short-term (4 h) and long-term memory (24 h). These findings support the conditioning nature of the new paradigm.  相似文献

Although theories of stress have emphasized the critical role of the appraisal process, the use of dispositional measures of appraisal have not been readily investigated. Using a large multiethnic sample, we examined the factorial validity and dimensionality of a dispositional version of the Stress Appraisal Measure (SAM; Peacock &; Wong, 1990). Both exploratory and confirmatory factor analyses resulted in a 4-factor representation of dispositional appraisal fitting better than its originally proposed 6-factor representation. This 4-factor model was invariant across gender groups. Although the 6-factor model purported to measure 3 dimensions of primary appraisal and 3 dimensions of secondary appraisal, these factors were found to be highly unstable and had questionable internal consistency. In contrast, the more parsimonious 4-factor solution identified 4 relative distinct and reliable scales of appraisal: 3 primary (Challenge, Threat, and Centrality) and 1 secondary (Resources). These findings suggest that meaningful dispositional dimensions of appraisal can be derived and incorporated into trait–state models of the stress process.  相似文献

After the Mexican Revolution (1910–1920), an ambitious project of national reconstruction began in which education and health were two priorities in the consolidation of a new nation. In this context of social, cultural, and political transformation, mental hygiene was a field that made it possible to articulate the professional practice of psychiatrists with the project of the nation promoted by postrevolutionary governments. In Mexico, the mental hygiene movement was headed by the same doctors who professionalized the practice of psychiatry and made it a specialized field of knowledge. The first generation of psychiatrists managed to integrate mental hygiene into health and education policies during the socialist administration of president Lázaro Cárdenas; a phenomenon that made evident the articulation between mental hygiene, social medicine, and nationalist discourse. Discussion will focus on proposals made from the perspective of mental hygiene as a function of two social sectors regarded as priorities by the Cárdenas government: children and workers.  相似文献

This article seeks to establish whether prosocial motivation in a sample of 251 volunteers is based on pleasure and not on pressure, which is related to the states of general well‐being (hedonic and eudaimonic measures) and the various states of well‐being specifically associated with volunteerism (volunteer satisfaction, volunteer engagement, and study enjoyment), all of this irrespective of the age of the volunteers. An analysis of partial correlations and linear regression leads to the conclusion that volunteerism undertaken as a non‐obligatory, planned helping activity, sustained over time and within an organizational context, is not always associated with positive effects in terms of well‐being. It seems that these positive effects are related to pleasure‐based prosocial motivation.  相似文献
