Recent works in epistemology show that the claim that coherence is truth conducive – in the sense that, given suitable ceteris paribus conditions, more coherent sets of statements are always more
probable – is dubious and possibly false. From this, it does not follows that coherence is a useless notion in epistemology
and philosophy of science. Dietrich and Moretti (Philosophy of science 72(3): 403–424, 2005) have proposed a formal of account of how coherence is confirmation conducive—that is, of how the coherence of a set of statements facilitates the confirmation of such statements. This account
is grounded in two confirmation transmission properties that are satisfied by some of the measures of coherence recently proposed in the literature. These properties
explicate everyday and scientific uses of coherence. In his paper, I review the main findings of Dietrich and Moretti (2005)
and define two evidence-gathering properties that are satisfied by the same measures of coherence and constitute further ways in which coherence is confirmation
conducive. At least one of these properties vindicates important applications of the notion of coherence in everyday life
and in science. 相似文献

The effects of a variable-ratio schedule of reinforcement on pedaling a stationary exercise bicycle were examined. Three obese and three nonobese 11-year-old boys were individually tested five times weekly for approximately 12 weeks. A changing-criterion design was used in which each successive criterion was increased over mean performance rate in the previous phase by approximately 15%. The contingencies of the successive criteria resulted in systematic increases in rate of exercise for all children. Final variable-ratio rates were higher than those under fixed ratios found in previous research, with rates for 2 of the 3 obese boys approximating those of the nonobese. 相似文献

Volunteering in emergency medical services (EMS) plays a fundamental role in the improvement and maintenance of collective and community health. However, this work often requires rescuers to deal with very stressful situations with consequences in terms of decreased quality of life and psychological well-being. The aim of this work was to analyze the resources that can be positively associated with volunteers’ quality of life. In particular, based on social identity and social cure approaches, we tested the effect of self-efficacy and identification with a volunteer category on both positive and negative aspects of the volunteers’ professional quality of life. A self-report questionnaire was administered to 203 EMS volunteers (53.7% men) from a large nonprofit volunteer association. Results are mostly supportive of predictions from the social identity (and specifically the “social cure”) approach, and show that professional identification and self-efficacy were differently linked to the dimensions of the volunteers’ quality of life. More precisely, professional identification was negatively associated with burnout and positively associated with compassion satisfaction, and both effects were mediated by self-efficacy. On the contrary, self-efficacy and volunteer identification were not associated with secondary traumatic stress. Practical implications for volunteers’ wellbeing are discussed in the light of the policies of volunteer associations to improve collective resources. 相似文献

IMPACT OF PARENTAL BINGE EATING DISORDER: EXPLORING CHILDREN'S EMOTIONAL/BEHAVIORAL PROBLEMS AND THE QUALITY OF PARENT–CHILD FEEDING INTERACTIONS 下载免费PDF全文

This study examines psychopathological problems in children of parents with binge eating disorder (BED), particularly the effect of parental diagnosis on their offspring's psychopathology and the mediating power of the quality of parent–infant feeding interactions. Two hundred parents and their offspring were administered a questionnaire for the assessment of their children's psychopathology at 18 (T1) and 36 (T2) months of age. An observational measure to evaluate feeding interactions was administered at T1. Children with both parents with BED showed the highest affective, anxiety, oppositional/defiant, and autism spectrum problems, but no influence of paternal diagnosis was found on the offspring's psychopathology. Maternal BED had an influence on children's affective and autism spectrum problems, and diagnosis of BED in both parents had an effect on infants’ affective problems. Paternal BED had an effect on oppositional/defiant problems through the quality of father–infant interactions, and maternal BED had an effect on the offspring's affective and anxiety problems through the mediation of mother–infant interactions. These results suggest the importance of intervention programs focusing both on parental psychopathology and on mother–child and father–child feeding interactions in families with parents with BED. 相似文献

Time processing impairments in preschoolers at risk of developing difficulties in mathematics 下载免费PDF全文
The occurrence of time processing problems in individuals with Development Dyscalculia (DD) has favored the view of a general magnitude system devoted to both numerical and temporal information. Yet, this scenario has been partially challenged by studies indicating that time difficulties can be attributed to poor calculation or counting skills, which can support reasoning on time in school‐aged children and adults. Here, we tackle this debate by exploring the performance of young children before they fully develop the symbolic number system. Preschoolers at risk of developing DD were compared with typically developing children in a series of tasks investigating time processing and in their ‘sense of time’, evaluated by parents and teachers. Results yielded a poorer performance in time reproduction of 5‐second intervals and in time discrimination, as well as a weaker ‘sense of time’, in children at risk of DD. These findings provide evidence of a common magnitude system that would be responsible for deficits in both numerical and temporal domains, already at early stages of life. 相似文献

Despite all the information about the risks, many people still smoke. Several studies investigated risk perceptions in smokers. The adequate perceptions of the risks from smoking is particularly important and this study investigated the risk perception of young smokers vs non-smokers by a new time-estimation task in which we required participants (smokers and non-smokers) to estimate the onset time of smoking-related conditions in an average young smoker. The findings supported our main hypothesis that smokers, compared to non-smokers, postponed the onset of both mild and severe smoking-related conditions. The results also revealed that the onset time estimates for mild conditions given by both smokers and non-smokers were associated with their self-perceptions of risk and level of fear of developing smoking-related conditions. The findings cast light on smokers’ distorted temporal perception of the health-damaging consequences of smoking. Implications for the adequacy of risk perception in smokers are discussed. 相似文献

Given that many patients referred to cardiac rehabilitation (CR) are obese, diet therapy, exercise training, nutritional and psychological counselling for both obesity and psychological distress should be included as important components in all CR programmes. In this practice-level, observational study we evaluated the short-term within-group effects of a four-week multi-factorial inpatient CR programme specifically addressed to weight loss, fitness improvement and psychological health increase on 176 obese in-patients with coronary heart disease (CHD). Outcome measures were exercise capacity measured with estimated metabolic equivalents (METs), body mass index (BMI) and psychological well-being (PGWBI). Results show statistically significant improvements in all the PGWBI sub-scales and total score, except in general health (p = 0.393). No moderation effects were found for BMI class, age, diabetes and ejection fraction (EF). METs significantly increased by 30.3% (p < 0.001) and BMI decreased by 1.37 points (p < 0.001). Significant correlations were found between BMI and weight reductions with PGWBI anxiety and total score improvements. This multi-disciplinary CR programme including diet therapy, exercise training and psychological counselling provides indication for short-term within-group effectiveness on functional exercise capacity, BMI and PGWBI in a sample of obese in-patients with CHD. However, controlled studies are needed to corroborate the results we found. 相似文献
