ObjectivesPrevious studies revealed that adolescence is a period of risk for doping and drug addiction and that young athletes who used doping agents reported low self-esteem. We conducted a preventive study with the aims to investigate whether young adolescents displayed an attentional bias to doping-related words and whether this attentional bias was related to physical self-esteem.MethodNinety seven adolescents (44 girls and 53 boys) from 11 to 15 years-old participated to a study designed to measure reaction times (RT) in a Stroop emotional task related to doping, cheating and control words. They also completed the Physical Self-Perception Profile subscales assessing perceived general self-esteem, physical self-worth, physical condition, sport competence, body attractiveness, and physical strength.ResultsParticipants exhibited longer RT after doping words than after control words. RT was also longer after doping than after cheating words. Participants belonging to the low physical self-esteem group exhibited larger carry-over effects than those who were in the high physical self-esteem group.ConclusionsThese findings suggest that attentional resources allocated to doping words are already present at the onset of adolescence, and that they may be linked to a psychological feature (physical self-esteem) considered as a risk factor of substance abuse in young adults involved in competitive sports.  相似文献

Commuting conversions were introduced in the natural deduction calculus as ad hoc devices for the purpose of guaranteeing the subformula property in normal proofs. In a well known book, Jean-Yves Girard commented harshly on these conversions, saying that ‘one tends to think that natural deduction should be modified to correct such atrocities.’ We present an embedding of the intuitionistic predicate calculus into a second-order predicative system for which there is no need for commuting conversions. Furthermore, we show that the redex and the conversum of a commuting conversion of the original calculus translate into equivalent derivations by means of a series of bidirectional applications of standard conversions.

This is a critical discussion of Nino B. Cocchiarella’s book “Formal Ontology and Conceptual Realism.” It focuses on paradoxes of hyperintensionality that may arise in formal systems of intensional logic.

This article focuses on the patterns of charitable giving among the foreign-born in Canada. Using Joseph's (1995) “spectrum of philanthropy” model, we generated four general empirical predictions that were explored with Canadian data. The sample used for the analysis were 18,301 Canadian and foreign-born respondents drawn from the National Survey of Giving, Volunteering and Participating. All four predictions were supported by the survey data. Substantial variations in the propensities to give were found among immigrant groups in terms of their birthplaces, socio-demographic, and residential characteristics. Some segments of the immigrant population displayed higher propensities to give than those who were Canadian-born. As the length of residence increased, the average contributions of the foreign-born increased but with some changes in their underlying motivations and organizational preferences. Religion-related motivations declined some-what over time. Although religious organizations were always preferred throughout the immigrant integration process, it was found that more secular organizations (i.e., health-and social services-related) received more support at the latter stages of this process.  相似文献

Rats trained to run a shuttle-alleyway for food exhibited exploratory behaviour to a novel visual/tactual stimulus presented in a specific place of the alley. Intermittent presentation of the same stimulus in the same place resulted in reduction of the exploratory activity (habituation), both within and between sessions. The animals also directed exploratory activity to the absence of the previously presented stimulus at the place where the stimulus had been presented before; this latter response also habituated. The presentation (1) of the same stimulus to which the animals had already habituated in another place in the alleyway or when the animals were running in an opposite direction to the previous trials of stimulus presentation, or (2) of another stimulus, resulted, again, in the appearance of exploratory activity. These results lead to the conclusion that the animals code external events, store this information, and use it to detect spatial- and directional-contextual changes and to generate predictions about that specific environment.  相似文献

Ignorance usually excuses from responsibility, unless the person is culpable for the ignorance itself. Since a lot of wrongdoing occurs in ignorance, the question of what makes ignorance culpable is central for a theory of moral responsibility. In this article I examine a prominent answer, which I call the ‘volitionalist tracing account,’ and criticize it on the grounds that it relies on an overly restrictive conception of responsibility‐relevant control. I then propose an alternative, which I call the ‘capacitarian conception of control,’ and on the basis of it I advance an account of culpable ignorance that avoids the skeptical upshots of the volitionalist proposal. If correct, my account establishes three important truths: agents can be directly in control of their ignorance, they can be directly responsible for more than actions and omissions, and their moral obligations extend beyond the performance of intentional actions and omissions.  相似文献

Self-concept consistency and short-term stability were investigated in the United States, Australia, Mexico, Venezuela, Philippines, Malaysia, China, and Japan. Evidence for substantial cross-role consistency and reliable within-individual variability in trait self-perceptions were found in each culture. Participants in all cultures exhibited short-term stability in their self-reported traits within roles and moderately stable if-then patterns of trait self-perceptions. Cultural differences, which primarily involved Japan, were partially accounted for by cultural differences in dialecticism, but not self-construals or cultural tightness. In all cultures, satisfaction of needs in various roles partially accounted for within-individual variability in self-reported traits. The results provide support for integrating trait and cultural psychology perspectives, as well as structure and process approaches, in the study of self-concepts across cultures.  相似文献

Neutral warning signals speed voluntary reactions by reducing temporal uncertainty and by triggering a brief burst of arousal. We attempted to isolate the phasic arousal mechanism in people with Parkinson's disease (PD) using a clock display to minimize temporal uncertainty. In this condition, the speeding of responses in a color-discrimination task by an accessory stimulus was the fully equivalent to the effect in age-matched control subjects. This indicates preserved phasic arousal in PD. Temporal preparation based on warning cues also appeared to be normal. By contrast, in a condition with high temporal uncertainty, the accessory stimulus (an air puff to the foot) impaired accuracy for the patients but not the neurologically normal subjects. The data are consistent with the view that PD disrupts internal but not external control of alertness.  相似文献

We examined the psychometric properties of the Spanish version of the self-report Personality Diagnostic Questionnaire-4+ (PDQ-4+) in a sample of 437 psychiatric outpatients. Psychometric properties were assessed through internal consistency analysis, exploratory factor analysis (EFA) and concurrent validity. Results indicate that the Spanish version of the PDQ-4+ has moderate internal consistency, which was acceptable for 7 of the 12 self-report scales. The factor structure roughly replicated the DSM-IV clusters. The presence of Personality Disorders was associated with the character dimensions of the Temperament and Character Inventory (TCI).  相似文献
