This study explores the influence of typical size during a categorization task. The specificity of this experimental work is based on the homogeneity of the graphic stimuli size. We have created a typical size standard of our stimuli, that concerns the real size of the objects represented by the drawings of homogeneous sizes. Then, a priming experiment was performed in which the prime and target drawings had two types of relations: a typical size, and a categorial. The participants are na?ve as to the typical size relation between prime and target. The results show a positive priming effect of the typical size but not of the category. The results are discussed in term of theoretical approach developed by Barsalou and his colleagues (1999, 2003). In this theoretical framework, the typical size can be considered as a perceptual knowledge. In that way, we propose that participants could automatically simulate the typical size as soon as they perceived the drawings of objects with homegenous sizes.  相似文献

This paper outlines specific methodologies for conducting research via computer networks. We discuss advantages of Internet experimentation over previous modes of telecommunication-facilitated research and characterize features of studies that can benefit from Internet access and those which are unlikely to. We point out pitfalls and suggest a range of potential solutions in terms of specific practical techniques for managing the design, dissemination, and collection of Internet materials. We also discuss techniques for minimizing attrition and for adapting to recalcitrance presented by “hacker” vandalism.  相似文献

This study investigated demographic variables, including affected sibling pair status, as risk factors for suicidal behavior in schizophrenia patients of African (Xhosa) descent. Xhosa subjects with schizophrenia were interviewed with the Diagnostic Interview for Genetic Studies (DIGS) and then stratified into two groups: those with ( n = 90) and those without ( n = 364) a history of previous suicide attempts. Demographic parameters (including gender, age, and social circumstances, sib ship) were then compared across these groups. Demographic predictors of suicide included sib ship status ( p = 0.038; OR = 1.7) and age of onset of illness ( p = 0.008; OR = 2.5). On further analysis of suicide in siblings, only a minority of sib pairs was found to be concordant for a lifetime history of suicide attempts (3%). These findings raise the possibility that affected sib pair status may be protective in nature. Given the counter-intuitive nature of this finding, further work is needed to replicate it, and to explore possible underlying mechanisms.  相似文献

Collective memory theories propose that groups' remembrances of their past depend upon their current social situation. In Belgium, a significant proportion of Dutch speakers share a collective memory of past victimisation by French speakers and fight for an ever‐larger autonomy of their region. Yet, as the respective economic, political and social situations of the linguistic regions of Belgium recently evolved with a reversal of fortunes, the current experience of younger Dutch speakers does not fit the traditional memory anymore. We thus predicted that the collective memories of victimhood would decline amongst them, thus bringing changes in intergroup attitudes and political aspirations. Three generations were compared in a survey of 1226 French‐speaking and 1457 Dutch‐speaking individuals. For both groups, younger generations evidenced less regionalist and more integrative positions than older ones. However, these effects were stronger for Dutch‐speaking respondents, and for them, collective memory of victimhood mediated the relation linking age and identification with Belgium, intergroup attitudes and political aspirations. We concluded that the current social context has decisive consequences for collective remembrances, which, in turn, impact intergroup relations and political attitudes and choices.  相似文献

It is well known that violent video games increase aggression, and that stress increases aggression. Many violent video games can be stressful because enemies are trying to kill players. The present study investigates whether violent games increase aggression by inducing stress in players. Stress was measured using cardiac coherence, defined as the synchronization of the rhythm of breathing to the rhythm of the heart. We predicted that cardiac coherence would mediate the link between exposure to violent video games and subsequent aggression. Specifically, we predicted that playing a violent video game would decrease cardiac coherence, and that cardiac coherence, in turn, would correlate negatively with aggression. Participants (N = 77) played a violent or nonviolent video game for 20 min. Cardiac coherence was measured before and during game play. After game play, participants had the opportunity to blast a confederate with loud noise through headphones during a reaction time task. The intensity and duration of noise blasts given to the confederate was used to measure aggression. As expected, violent video game players had lower cardiac coherence levels and higher aggression levels than did nonviolent game players. Cardiac coherence, in turn, was negatively related to aggression. This research offers another possible reason why violent games can increase aggression—by inducing stress. Cardiac coherence can be a useful tool to measure stress induced by violent video games. Cardiac coherence has several desirable methodological features as well: it is noninvasive, stable against environmental disturbances, relatively inexpensive, not subject to demand characteristics, and easy to use.

ABSTRACT

Like the Canadian landscape and culture, the status of professional regulation for counselling and psychotherapy is a mosaic reflecting the unique cultural, linguistic and contextual realities of Canada. Statutory regulation in Canada is constitutionally a provincial/territorial matter. In the past five years, a major movement towards professional regulation has emerged. The authors describe the variable status of regulation, focusing on three provinces: Quebec, Nova Scotia and Ontario. They explore the federal Agreement of Internal Trade, designed to facilitate inter-provincial/territorial mobility of regulated professionals. Finally, the authors summarise national research and development activities of the Canadian Counselling and Psychotherapy Association that enhance the pan-Canadian mobility of practitioners and support shared professional understandings. These activities range from bilingual, national validation of competencies, definitions, titles and scopes of practice to symposia and an entry-to-practice competency assessment.  相似文献

ABSTRACT

The study of memory for famous people and visual imagery retrieval was investigated in patients in the early stages of Alzheimer's disease (AD) and in the prodromal stage of AD, so-called Mild Cognitive Impairment (MCI). Fifteen patients with AD (MMSE ≥23), 15 patients with amnestic MCI (a-MCI) and 15 normal controls (NC) performed a famous names test designed to evaluate the semantic and distinctive physical features knowledge of famous persons. Results indicated that patients with AD and a-MCI generated significantly less physical features and semantic biographical knowledge about famous persons than did normal control participants. Additionally, significant differences were observed between a-MCI and AD patients in all tasks. The present findings confirm recent studies reporting semantic memory impairment in MCI. Moreover, the current findings show that mental imagery is lowered in a-MCI and AD and is likely related to the early semantic impairment.  相似文献

This study addresses the relation between lexico-semantic body knowledge (i.e., body semantics) and spatial body representation (i.e., structural body representation) by analyzing naming performances as a function of body structural topography. One hundred and forty-one children ranging from 5 years 2 months to 10 years 5 months old were asked to provide a lexical label for isolated body part pictures. We compared the children’s naming performances according to the location of the body parts (body parts vs. head features and also upper vs. lower limbs) or to their involvement in motor skills (distal segments, joints, and broader body parts). The results showed that the children’s naming performance was better for facial body parts than for other body parts. Furthermore, it was found that the naming of body parts was better for body parts related to action. These findings suggest that the development of a spatial body representation shapes the elaboration of semantic body representation processing. Moreover, this influence was not limited to younger children. In our discussion of these results, we focus on the important role of action in the development of body representations and semantic organization.  相似文献

This research examines the role of alcohol consumption on self‐perceived attractiveness. Study 1, carried out in a barroom (N= 19), showed that the more alcoholic drinks customers consumed, the more attractive they thought they were. In Study 2, 94 non‐student participants in a bogus taste‐test study were given either an alcoholic beverage (target BAL [blood alcohol level]= 0.10 g/100 ml) or a non‐alcoholic beverage, with half of each group believing they had consumed alcohol and half believing they had not (balanced placebo design). After consuming beverages, they delivered a speech and rated how attractive, bright, original, and funny they thought they were. The speeches were videotaped and rated by 22 independent judges. Results showed that participants who thought they had consumed alcohol gave themselves more positive self‐evaluations. However, ratings from independent judges showed that this boost in self‐evaluation was unrelated to actual performance.  相似文献
