Similarity between a solicitor and a subject traditionally enhances helping behavior. An experiment was carried out in a computer‐mediated context. Fifty students received an e‐mail containing a 40‐question survey on their food habits, which required 15 to 20 min of their time to respond. This questionnaire came from a hypothetical student of the university in which the participants were registered. In half of the cases, the surname of the solicitor, which appeared in his or her electronic address, was the same as the surname of the target. Results show that compliance to the request was significantly higher in the same‐sumame condition than in the different‐surname condition. The response delay was significantly shorter in the same‐surname condition than in control condition. 相似文献

Research has demonstrated that more accessible cognitive constructs (e.g., attitudes, stereotypes) are more likely to influence thoughts and behaviors. The current research applies a social cognition framework to the prediction of romantic relationship persistence (i.e., “stay‐leave” behavior), accommodation, and willingness to sacrifice. Conceptualizing commitment as a partially cognitive construct and following from social cognition and attitudinal research, we hypothesized that the accessibility of commitment will moderate the association between commitment and relationship persistence, accommodative responses, and willingness to sacrifice. In Study 1, participants in romantic relationships responded to statements derived from the commitment subscale of the Investment Model Scale. Reaction times to these statements were used as a measure of accessibility of commitment. In addition, participants completed measures of their commitment level. Seven months later, participants were contacted and relationship persistence was assessed. Accessibility of commitment significantly moderated the association between commitment and relationship persistence. Study 2 expanded on the results of the first study by demonstrating that accessibility of commitment also significantly moderated the association between commitment and accommodation and willingness to sacrifice. Taken together, these two studies highlight the usefulness of applying social cognitive concepts to understand close relationships. 相似文献

In this article, we present a new lexical database for French: Lexique. In addition to classical word information such as gender, number, and grammatical category, Lexique includes a series of interesting new characteristics. First, word frequencies are based on two cues: a contemporary corpus of texts and the number of Web pages containing the word. Second, the database is split into a graphemic table with all the relevant frequencies, a table structured around lemmas (particularly interesting for the study of the inflectional family), and a table about surface frequency cues. Third, Lexique is distributed under a GNU-like license, allowing people to contribute to it. Finally, a metasearch engine, Open Lexique, has been developed so that new databases can be added very easily to the existing ones. Lexique can either be downloaded or interrogated freely from http://www.lexique.org. 相似文献

Using the autobiographical directed forgetting method (Barnier et al., 2007), the present paper addressed the intentional inhibitory processes of episodic and semantic autobiographical memory in Alzheimer's disease (AD). Mild AD patients and healthy elderly people were instructed to either forget or to continue remembering previously generated autobiographical events. In a later recall test they were asked to reconstruct the early-generated memories regardless of the forget/remember instruction. Autobiographical reconstruction was further distributed into episodic and semantic memories. Results showed no forget instruction effect on episodic or semantic autobiographical recall with AD patients, whereas healthy elderly people were able to inhibit only episodic autobiographical memories. The findings suggest an impairment of the intentional inhibitory processes in autobiographical memory with AD and a relative preservation of these mechanisms with normal ageing. They also demonstrate an earlier decline in the intentional inhibitory processes compared to the autobiographical deterioration in AD. 相似文献

Endocannabinoids (eCBs) modulate a variety of brain functions via activation of the widely expressed CB1 receptor. One site of high density of this receptor is the basolateral amygdala (BLA), a structure involved in the formation of aversive memories. The activation and blockade of CB1 receptors by systemic or hippocampal drug administrations have been shown to modify memory processing. However, little is known about the role of the BLA endocannabinoid system in aversive memories. Additionally, BLA endocannabinoid transmission seems to be related to emotional states, but the relevance of these effects to memory formation is still unknown. In this study we investigated the effects of the eCB anandamide (AEA) and the CB1 antagonist/inverse agonist AM251 infused into the BLA on the acquisition of an aversive memory task, concomitantly evaluating basal anxiety levels in rats. Male rats received pre-training micro-injection of AEA, AM251 or vehicle bilaterally into the BLA, and were studied with the plus-maze discriminative avoidance task (a paradigm that allows concomitant and independent evaluation of anxiety-like behavior and the memory of an aversive task). Our results showed that AEA into the BLA before training prevented memory retrieval 24 h later, as evaluated by exploration of the aversive arm of the maze, while AM251 into the BLA did not interfere with animals' performance. In addition, AEA had no effect on anxiety-like behavior (as evaluated by open arm exploration and risk assessment), while AM251 induced an anxiogenic effect. Our data indicate an important role of BLA CB1 receptors in aversive memory formation, and suggest that this involvement is not necessarily related to a possible modulation of anxiety states. 相似文献

The association between the Five-Factor Model of personality (FFM) and antisocial personality disorder (APD) symptoms was
investigated in a sample of young males with a history of severe antisocial behavior. Results were compared against those
of an expert-consensus study (Lynam and Widiger Journal of Abnormal Psychology 110:401–412, 2001) and those of a recent meta-analysis (Samuel and Widiger Clinical Psychology Review 28:1326–1342, 2008) based primarily on non-antisocial samples. A high degree of similarity was observed across the three. Multivariate analysis
indicated two FFM facets, Compliance and Activity, to be associated with APD symptoms. The contribution of these facets to
the prospective prediction of antisocial behavior over and above that of APD symptoms and past antisocial behavior was evaluated.
Compliance alone explained 8.7% of the unique variance in future antisocial behavior. 相似文献

We investigated the role of vision in tactile enumeration within and outside the subitizing range. Congenitally blind and
sighted (blindfolded) participants were asked to enumerate quickly and accurately the number of fingers stimulated. Both groups
of participants enumerated one to three fingers quickly and accurately but were much slower and less accurate with four to
nine fingers. Within the subitizing range, blind participants performed no differently from both sighted (blindfolded) and
sighted-seeing participants. Outside of the subitizing range, blind and sighted-seeing participants showed better performance
than did sighted-blindfolded participants, suggesting that lack of access to the predominant sensory modality does affect
performance. Together, these findings further support the claim that subitizing is a general perceptual mechanism and demonstrate
that vision is not necessary for the development of the subitizing mechanism. 相似文献

Multiculturalism constitutes an important element of school climate, but the relation between perceived multiculturalism and academic achievement has not been widely studied. This study examined the influence of students' perceptions of school support for multiculturalism on academic achievement among 280 Asian American and Hispanic youth, including ethnic identity and ethnocultural empathy as potential mediators. Results of structural equation modeling revealed that perceived multiculturalism was significantly positively related to ethnocultural empathy for Asian Americans and Hispanics, and that ethnocultural empathy, in turn, was predictive of academic achievement for Hispanics only. Results of bootstrapping to test for mediation effects revealed ethnocultural empathy to be a salient mediator for Hispanic youth. Although ethnic identity did not mediate the link between multiculturalism and academic achievement, ethnic identity was significantly predictive of achievement for Hispanics. On the whole, these findings suggest that fostering a school climate supportive of multiculturalism may improve empathy toward ethnic out-groups. Furthermore, schools that promote compassion and tolerance for diverse ethnic groups may achieve better academic outcomes among Hispanic youth. 相似文献
