Human music perception is related both to musical experience and the physical properties of sound. Examining the processing of music by nonhuman animals has been generally neglected. We tested both black-capped chickadees and humans in a chord discrimination task that replicates and extends prior research with pigeons. We found that chickadees and humans, in common with pigeons, showed similar patterns of discrimination across manipulations of the 3rd and 5th notes of the triadic chords. For all species (chickadee and humans here, pigeons previously), chords with half-step alterations in the 5th note were easier to discriminate than half-step manipulations of the 3rd note, which is likely due to the sensory consonance of these chords. There were differences among species in terms of the fine discrimination of the chords within this larger pattern of results. Further, the ability to relearn the chords when transposed to a new root differed across species. Our results provide new comparative data suggesting some similarities in chord perception that span a wide range of species, from pigeons (nonvocal learners) to songbirds and humans (vocal learners).  相似文献

We examined college students' participation in a game activity for studying course material on their subsequent quiz performance. Game conditions were alternated with another activity counterbalanced across two groups of students in a multielement design. Overall, the mean percentage correct on quizzes was higher during the game condition than in the no-game condition.  相似文献

This study investigated accuracy (veridicality) and perspective (point of view) in everyday involuntary memories (i.e. spontaneous recollections of the past). Using the naturalistic diary method, subjects were asked to give confidence ratings on the accuracy of their involuntary memories as well as contact others who were present in them, having them also give confidence ratings. Memory perspective was assessed by asking subjects to indicate whether their memories had a field (original) or observer (the perspective of another) point of view. The results showed subjects assigning high confidence ratings to involuntary memories, which did not differ from the confidence ratings given by others, or from the confidence ratings that they had assigned to their voluntary memories. The perspective query showed that involuntary memories come with both field and observer perspectives, and that their relative proportions did not differ from those reported for their voluntary memories.

Most theories of motivation and behavior (and lay intuitions alike) consider pain and effort to be deterrents. In contrast to this widely held view, we provide evidence that the prospect of enduring pain and exerting effort for a prosocial cause can promote contributions to the cause. Specifically, we show that willingness to contribute to a charitable or collective cause increases when the contribution process is expected to be painful and effortful rather than easy and enjoyable. Across five experiments, we document this “martyrdom effect,” show that the observed patterns defy standard economic and psychological accounts, and identify a mediator and moderator of the effect. Experiment 1 showed that people are willing to donate more to charity when they anticipate having to suffer to raise money. Experiment 2 extended these findings to a non‐charity laboratory context that involved real money and actual pain. Experiment 3 demonstrated that the martyrdom effect is not the result of an attribute substitution strategy (whereby people use the amount of pain and effort involved in fundraising to determine donation worthiness). Experiment 4 showed that perceptions of meaningfulness partially mediate the martyrdom effect. Finally, Experiment 5 demonstrated that the nature of the prosocial cause moderates the martyrdom effect: the effect is strongest for causes associated with human suffering. We propose that anticipated pain and effort lead people to ascribe greater meaning to their contributions and to the experience of contributing, thereby motivating higher prosocial contributions. We conclude by considering some implications of this puzzling phenomenon. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Objectives: This study investigates the efficacy of a standard cognitive behavioral group-program for chronic pain, in comparison with the same group program that integrates an existential perspective at treatment conclusion, 3-month, and 6-month follow-up. Design: This study is a quasi-experimental clinical trial with two treatment groups. Methods: We included 113 patients suffering from chronic pain who had been accepted for treatment at an interdisciplinary pain center. In addition to the specific therapy program, the patients received intense interdisciplinary treatment. Outcome measures include both pain-related disability and pain severity. Repeated-measures analyses of variance (ANOVAs) were used to test statistical significance, followed by tests of simple contrasts with pre-treatment as a reference-point. Results: Results indicated that the integration of an existential perspective leads to significantly lowered pain-related disability than the classic cognitive behavioral group-program. Additionally, existential aspects seem to be particularly important for patients with a spiritual orientation. The findings from this study support the importance of considering specific existential aspects in the cognitive-behavioral approach in treating chronic illness.  相似文献

The authors use a portfolio of sequential tasks to investigate how accurately study participants stick to assigned deadlines when they need to transition from one task to another. Atypical deadlines, task complexity, and individual differences all affect transition error size, error correction, and task performance. In Experiment 1 (N?=?108), larger task transition errors were related negatively to task performance and were associated with atypical deadlines (e.g., 4:53 or 4:57), complex tasks, and individuals lower in the general hurry characteristic. In Experiment 2 (N?=?95), individuals facing atypical deadlines or lower in need for cognition were less likely to correct transition errors (i.e., getting back to the original schedule), which negatively affected performance. Theoretical and practical implications are discussed.  相似文献

Soldiers (N = 95) reported emotions and emotion regulation strategies experienced in their first parachute jump and other challenging situations. Results indicated an emotional profile characterized by feeling anxious, energetic, and happy before parachuting and playing sport. However, this pattern was not similar to the emotional responses experienced at work or in life in general. Participants reported greater use of strategies to increase unpleasant emotions an hour before parachuting than in other situations. Findings suggest that developing training protocols to increase the flexibility and versatility of emotion regulation skills might enhance the preparation of novice soldiers for military duties.  相似文献

Drawing from normal accident theory, high reliability theory, and systems theory, we analyze the Charter for the Protection of Children and Young People that is promulgated by the United States Conference of Catholic Bishops in response to the sexual abuses of minors by clergy members. Although the Charter is a step in the right direction, there remain some areas that require immediate attention. In spite of the goodwill processes, the safety of minors must remain the concerted efforts and responsibilities of individuals at all the various levels if the Catholic Church is to prevent further cases of abuse from happening.  相似文献
