A common belief about the nature of agent regret is that regretting some event E is closely linked to being sorry for the occurrence of E. Or more specifically, that if one is sorry for E then she must regret E. I will call this ‘the sorry‐regret hypothesis’. My contention is that one may be sorry for some action but not regret it. I take the rejection of this ‘truism’ to be a positive development. I offer two lines of argument for rejecting the sorry‐regret hypothesis. One line of argument is based on counterexamples. The second attacks the validity of a reconstructed argument for the sorry‐regret hypothesis. It is desirable to reject the sorry‐regret hypothesis since there is a component of regret that many will not wish to be saddled with as a condition of apologizing. To regret an act, one must wish that she had not performed that act. Since a person is the person she is (speaking loosely) because of the actions she has performed, for many actions, if one regrets an action, then she wishes that she were a different person. This is a worrisome consequence.  相似文献

Previous research has shown that rats can learn matching-to-sample relations with olfactory stimuli; however, the specific characteristics of this relational control are unclear. In Experiment 1, 6 rats were trained to either match or nonmatch to sample in a modified operant chamber using common household spices as olfactory stimuli. After matching or nonmatching training with 10 exemplars, the contingencies were reversed with five new stimuli such that subjects trained on matching were shifted to nonmatching and vice versa. Following these reversed contingencies, the effects of the original training persisted for many trials with new exemplars. In Experiment 2, 9 rats were trained with matching procedures in an arena that provided for 18 different spatial locations for comparison stimuli. Five subjects were trained with differential reinforcement outcomes and 4 with only one type of reinforcer. Differential outcomes and multiple exemplars facilitated learning, and there was strong evidence for generalization to new stimuli for most rats that acquired several conditional discriminations. Performances with novel samples were generally above chance, but rarely reached the high levels obtained during baseline with well-trained stimulus relations. However, taken together, the data from the two experiments extend previous work, show that rats can learn both match and nonmatch relations with different experimental protocols, and demonstrate generalization to novel sample stimuli.  相似文献

Three experiments were conducted to examine the effect of phonological similarity in simple and complex memory span tasks. In Experiment 1, participants performed either a simple or a complex span task, and the memoranda within lists were either phonologically similar or distinct. Phonologically similar lists consisted of words that rhymed.The simple span task was word span. There were two complex span tasks; one was the original reading span task, and the other was a variant of reading span in which all the sentences within a list were contextually related. The classic phonological similarity decrement was observed in word span. In contrast, phonological similarity facilitation was observed in both versions of reading span. This facilitation effect was further investigated in Experiment 2 using two new versions of reading span. In Experiment 2, the sentences in reading span were either short or long, and the memoranda were presented separately from, and were unrelated to, the sentences. Again, words within phonologically similar lists rhymed, and again, facilitation was observed. In Experiment 3, phonological similarity was operationalized in terms of feature overlap, rather than rhyme. The classic phonological similarity decrement was still observed in word span, but facilitation was not observed in complex span. The results suggest that phonological similarity, when operationalized using words that rhyme, serves as a list retrieval cue and that complex span tasks are more dependent on cue-driven memory retrieval mechanisms than are simple span tasks.  相似文献

This study examined the association between childhood ADHD and juvenile delinquency by examining data from the Pittsburgh ADHD Longitudinal Study (PALS), a follow-up study of individuals diagnosed with ADHD in childhood (ages 5–12) and recontacted in adolescence and young adulthood for yearly follow-up (age at first follow-up interview M = 17.26, SD = 3.17). Participants were 288 males with childhood ADHD and 209 demographically similar males without ADHD who were recruited into the follow-up study. Delinquency information gathered yearly during the second through eighth follow-up provided a comprehensive history of juvenile delinquency for all participants. Four childhood diagnostic groups [ADHD-only (N = 47), ADHD + ODD (N = 135), ADHD + CD (N = 106), and comparison (N = 209)] were used to examine group differences on delinquency outcomes. Analyses were conducted across three dimensions of delinquency (i.e., severity, age of initiation, and variety). Individuals with childhood ADHD + CD displayed significantly worse delinquency outcomes than the other three groups, across almost all indices of offending. When compared to comparison participants, boys with ADHD-only and ADHD + ODD in childhood displayed earlier ages of delinquency initiation, a greater variety of offending, and higher prevalence of severe delinquency. These findings suggest that although childhood ADHD + CD creates the greatest risk for delinquency, boys with ADHD-only and ADHD + ODD also appear at a higher risk for later offending. The patterns of offending that emerged from the PALS are discussed in the context of the relationship between ADHD, comorbidity, and delinquency.  相似文献

Advances in whole genome and whole exome sequencing (WGS/WES) technologies have led to increased availability in clinical settings. Currently, there are few guidelines relating to the process and content of informed consent for WGS/WES, nor to which results should be returned to families. To address this gap, we conducted focus groups to assess the views of professionals, parents, and adolescents for the future implementation of WES. The discussions assessed understanding of the risks and benefits of WES, preferences for the informed consent discussion, process for return of results, and the decision-making role of the pediatric patient. Professional focus group participants included bioethicists, physicians, laboratory directors, and genetic counselors. Parent focus groups included individuals with children who could be offered sequencing due to a potential genetic cause of the child’s condition. On-line discussion groups were conducted with adolescents aged 13–17 who had a possible genetic disorder. We identified discrepancies between professionals and patient groups regarding the process and content of informed consent, preference for return of results, and the role of the child in decision-making. Professional groups were concerned with the uncertainty regarding professional obligations, changing interpretation in genomic medicine, and practical concerns of returning results over time. Parent and adolescent groups focused on patient choice and personal utility of sequencing results. Each group expressed different views on the role of the child in decision-making and return of results. These discrepancies represent potential barriers to informed consent and a challenge for genetic counselors regarding the involvement of pediatric patients in decision-making and return of results discussions.  相似文献

Meditation in Thailand’s international meditation centers is presented in advertisements as both a universal practice and a cultural icon that links Thailand to its ancient past. National religions and religious symbols serve to re-inscribe particular images, places, and practices as part of the national heritage. The practice of meditation is contextualized within Thailand and Thai culture, while it is also de-contextualized as a universal practice in which international meditators can participate. At the national level, meditation is a marker of Thailand’s difference and exoticism. At the same time as Thailand’s otherness is highlighted, meditation is also connected with universal systems of science and rationality. I argue that these selective elements serve to reinforce consumer values and constitute a commodification of meditation for tourists. I demonstrate that this does not detract from the practice for foreign communities, but that it is an example of the creative adaptations for reaching a wide variety of audiences. By looking at meditation guidebooks and promotional materials about meditation, this article contributes to scholarly dialogues of the commodification of religious practices.  相似文献

The present study investigated relationships between media influence (exposure, self-comparison to media ideals and internalization of media messages, societal pressure to have the perfect body, using media as a source of information about how to achieve a certain body ideal) and drive for thinness and drive for muscularity in 311 male and female undergraduates at a university in the Rocky Mountain region of the United States. We hypothesized that drive for thinness and drive for muscularity in both women and men would relate to body comparison/internalization, societal pressure, use of media for information, magazine consumption and television viewing. We also expected television and magazines would have different influences on men and women’s drive for muscularity and drive for thinness. Finally, we hypothesized that societal pressure and using media as a source of information would mediate the relation between media exposure (number of magazines read, hours of television watched) and drive for thinness and drive for muscularity in women and men. Students completed surveys on-line. Results revealed using media as a source of information on how to attain the ideal body mediates the relationship between drive for thinness and media exposure in women. Overall, it seems that media and the internalization of general/non-athletic body ideals may have an impact on drive for thinness in both men and women. Similarly, internalization of athletic body ideals may relate to drive for muscularity in both collegiate men and women in the U.S. Implications for counselors were discussed.  相似文献

It is widely recognized that abdominal pain and discomfort are common problems in the United States and are often associated with negative quality of life. The prevalence of anxiety/depression elevations and disorders among persons with gastrointestinal disturbances (GI) is estimated to be at least two to three times the rate in the general population. Visceral sensitivity reflects anxiety about GI sensations and its accompanying contexts and often leads to worsening of sensations (e.g. bloating, upset stomach, diarrhea). Among individuals with GI symptoms, visceral sensitivity may be associated with interpreting common sensations as catastrophic which may be related to greater difficulties with emotion dysregulation (e.g. severe anxiety and depression). The current study evaluated the indirect association of visceral sensitivity via emotion dysregulation in relation to depression, anxious arousal, and social anxiety symptoms among 344 young adults with a current history of GI symptoms and problems. Results indicated an indirect effect of visceral sensitivity via emotion dysregulation. These findings provide novel empirical support for the association of visceral sensitivity with emotional distress symptoms among young adults with GI symptoms. Based on the results, targeting emotion dysregulation may be a promising health promotion tactic among young adults with GI symptoms and disorders.  相似文献
