Word-fragment completion is a frequently used test in implicit memory research. A database of 196 Spanish fragments was recently published (Dasí, Soler, & Ruiz, 2004) in which the fragments were described for indices, such as difficulty, familiarity, frequency, number of meanings, and so on (www.psychonomic.org/archive). In this work, a new index, the priming index, is described for the same 196 fragments. This index is calculated for each fragment by subtracting the difficulty index (the proportion of correct completion when the fragment is not studied) from the proportion of correct completion when the fragment is studied, and it means the capacity of an item to be primed. In order to determine whether the new index performs well, we have replicated some important experimental effects, such as priming, frequency, and difficulty. We consider that this index can help researchers to better select stimuli for fragment-completion tasks. 相似文献

We approach the problem about relationships between personality dimensions and the use of coping strategies in chronic pain patients. The most frequently used theoretical model in the area of stress and its relation to pain is the transactional model, taking into account that the incorporation of personality traits improves predictions via coping in the stress process. Following the Big Five model, the relationships between personality and coping strategies in patients with chronical neuropathic pain were established. The results showed slight relationships between the Big-Five dimensions and coping. A vulnerable personality profile in patients with chronic neuropathic pain was obtained, consisting of high neuroticism, low extraversion, openness to experience and responsibility, and moderate agreeableness. 相似文献

Working memory deficits are present in a substantial proportion of children with ADHD, and converging evidence links these deficits with ADHD-related behavioral and functional impairments. At the same time, working memory is not a unitary construct, and evidence is lacking regarding the role of several components of this system in ADHD. Preclinical behavioral studies are needed to fractionate the multicomponent working memory system, determine which specific subcomponent(s) are impaired in ADHD, and more importantly link these subcomponent(s) with specific ADHD-related behavioral symptoms/functional impairments. The current study reflects one piece of that puzzle, and focuses on the episodic buffer component of working memory. Across multiple testing days, a well-characterized sample of 86 children ages 8–13 (M=10.52, SD=1.54; 34 girls; 64% Caucasian/Non-Hispanic) with ADHD (n=49) and without ADHD (n=37) completed three counterbalanced working memory tests that were identical in all aspects except the key subcomponent process (phonological, visuospatial, episodic buffer). Gross motor movement during these and control tasks were measured using 4 high-precision actigraphs. There was no evidence of group differences in gender, age, SES, or IQ. Bayesian mixed-model ANOVAs indicated that the ADHD group performed significantly worse on all three working memory tests (d=1.17–1.44) and was significantly more hyperactive than controls (d=0.66–1.05) during the visuospatial and episodic buffer tests. In contrast, the ADHD and Non-ADHD groups were equivalent with regard to effects of episodic buffer demands on performance and hyperactive behavior. The most parsimonious conclusion is that the episodic buffer is likely intact in ADHD, and unrelated to ADHD hyperactivity symptoms. 相似文献

It was predicted that negative affect associated with one component of air pollution (malodor) reduces attraction toward both similar and dissimilar strangers. In one experiment, 27 subjects rated attitudinally similar or dissimilar strangers while confined in a room whose atmosphere was ambient (no-odor control) or polluted by ammonium sulfide. Contrary to predictions, similar strangers elicited greatest liking in the polluted atmosphere. It was suggested that air pollution had increased attraction for another who might be experiencing the same disagreeable situation (i.e., “shared stress”). In a second experiment, this suggestion was examined by assuring subjects that they were alone and would not meet the similar or dissimilar person they rated. As predicted, exposure to either ammonium sulfide or butyric acid combined additively with attitudinal dissimilarity to depress liking, mood-affect, time spent in the setting, and ratings of the environment. These results were viewed as consistent with the reinforcement-affect model of attraction, but it was cautioned that the effects of air pollution may depend on social factors, such as shared stress, and dosage level of the pollutant. 相似文献

The aims of the present study were to examine the factor validity of a new social behavior assessment - the Social Behavior Scale (SBS) - using exploratory (sample 1, n = 169) and confirmatory (sample 2, n = 127) factor analysis, and to test factor invariance across gender in a sample of Italian preschoolers. The concurrent validity of the SBS was examined with measures of peer nominations and observed interactions (sample 3, n = 277). Findings confirmed the three-factor structure of the SBS: Emotional Competence, Social Engagement and Aggressiveness. Multigroup analysis provided evidence of factor invariance across gender. Concerning concurrent validity, results confirmed a great association between teacher-rating SBS and the other concurrent measures. 相似文献

A recent study found that guppies (Poecilia reticulata) can be trained to discriminate 4 versus 5 objects, a numerical discrimination typically achieved only by some mammals and birds. In that study, guppies were required to discriminate between two patches of small objects on the bottom of the tank that they could remove to find a food reward. It is not clear whether this species possesses exceptional numerical accuracy compared with the other ectothermic vertebrates or whether its remarkable performance was due to a specific predisposition to discriminate between differences in the quality of patches while foraging. To disentangle these possibilities, we trained guppies to the same numerical discriminations with a more conventional two-choice discrimination task. Stimuli were sets of dots presented on a computer screen, and the subjects received a food reward upon approaching the set with the larger numerosity. Though the cognitive problem was identical in the two experiments, the change in the experimental setting led to a much poorer performance as most fish failed even the 2 versus 3 discrimination. In four additional experiments, we varied the duration of the decision time, the type of stimuli, the length of training, and whether correction was allowed in order to identify the factors responsible for the difference. None of these parameters succeeded in increasing the performance to the level of the previous study, although the group trained with three-dimensional stimuli learned the easiest numerical task. We suggest that the different results with the two experimental settings might be due to constraints on learning and that guppies might be prepared to accurately estimate patch quality during foraging but not to learn an abstract stimulus–reward association. 相似文献

This article presents complexity (nonlinearity, chaos, self-organisation, fractals...) as a new and emerging epistemological paradigm, an alternative to an old, simpler, and reductionist paradigm. According to this point of view, we try to view work organizations as complex adaptive systems (CAS). Lastly, we offer a review of the literature on the applications of complexity to Organizational Social Psychology. 相似文献

A world without individual entities? An advice to not to extract immediate ontological consequences from quantum theory. Should we assume a world without individual entities? I pledge not to extract immediate ontological consequences from quantum theory. My intention is to focus on the complexity of ontological concepts commonly associated with quantum theory. Using as an example the compatibility of EPR correlations with the existence of individual entities, it is shown that an absolute rejection of an ontological category, based on some aspects of the formalism of quantum theory, does not seem reasonable. A consequence of this argument is that the common sense view – the world is composed of individual entities – can be maintained, despite of the particularities of quantum mechanics. 相似文献

LGBT Community, Social Network Characteristics, and Smoking Behaviors in Young Sexual Minority Women
Michelle Marie Johns Emily S. Pingel Emily J. Youatt Jorge H. Soler Sara I. McClelland Jose A. Bauermeister 《American journal of community psychology》2013,52(1-2):141-154
Smoking rates among young sexual minority women (YSMW) are disproportionately high as compared to heterosexual populations. While this disparity has commonly been attributed to the sexual minority stress process, little empirical work has explored what may protect YSMW from high rates of smoking. Using data (N = 471) from a cross-sectional study designed to investigate YSMW’s (age 18–24) smoking behaviors and correlates; we explore the relationship of LGBT community connections, YSMW’s social network characteristics, and stress to smoking behaviors (i.e., status, frequency, amount). Through this analysis, we find support for LGBT community connection as well as friendships with other sexual minorities as protective in relation to YSMW’s smoking behaviors. We discuss the implications of our results, highlighting the need for future longitudinal research and interventions designed to bolster YSMW’s connections to the LGBT community and their social networks. 相似文献

Abstract This study investigated whether measures of three perceived control (PC) concepts tapped independent dimensions, were invariant to population characteristics of health and culture, were differentially sensitive to health outcomes, and were discriminable from self-report disability. The Multidimensional Health Locus of Control, Generalized Self-efficacy, and Perceived Health Competence (PHC) Scales were administered to 106 Scottish students and 145 Scottish, Spanish and Irish patients, who also completed versions of the Sickness Impact Profile. Principal Components analyses revealed five factors reflecting scale constructions for students and six factors for patients, as PHC items fell on two factors. Disability items fell on a separate factor from all PC items. Results suggest: (a) PC is multidimensional regardless of health and culture; (b) adequate assessment requires multiple PC measures; and (c) it is meaningful to consider PC as a possible influence on disability. 相似文献
