Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians 总被引:1,自引:0,他引:1

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

The Induction of Mood via the WWW 总被引:1,自引:0,他引:1

Five experiments explored the methodology of Web-based mood induction and yielded empirical evidence for its feasibility and its limits. Study 1 examined the suitability of the Velten method and mood-suggestive photographs to induce both positive and negative moods. Negative mood was successfully induced, while the positive mood induction failed. In Study 2, cartoons successfully ameliorated mood, whereas jokes were ineffective. In Study 3, associations with affectively valenced words were not suitable in producing a positive or a negative mood. In Study 4, picture-illustrated emotive texts successfully induced a positive and a negative mood. In Study 5, valence and arousal ratings were obtained for the stimuli used in Study 1 and 3. Based on the results, recommendations for the application of online mood induction procedures are given. 相似文献

This study longitudinally investigated the quality and stability of 64 infants’ interactions with their professional caregivers in child care centers at 3 and 6 months of age, i.e., across the first 3 months after they entered child care. It was also examined whether the infants’ negative emotionality (as rated by the mother) predicted the quality of the caregiver–infant interaction. The interactive behavior of the professional caregivers (sensitivity, cooperation) and the infants (responsiveness, involvement) was rated from videotapes recorded in three different caregiving situations, lasting about 25 min in total. In contrast to our expectation, the quality of the caregiver–infant interaction did not significantly increase across the first 3 months in child care. As expected, significant rank order stability was found for the quality of the caregivers’ behavior over time. Also in accordance with our expectations, infants with higher negative emotionality scores experienced less sensitivity and cooperation in interactions with their primary professional caregivers at both ages. 相似文献

This study examined the possibility to improve accuracy of age estimates through training. Thirty‐four participants were divided into an experimental and a control group. The sessions included a pre‐test before training, six feedback or no‐feedback training tests and a post‐test after training. The experimental group performed the feedback tests and the control group the no‐feedback tests. Training was found to improve age estimation accuracy, particularly estimations of old stimuli, and training with feedback seemed to be superior to training without feedback. No difference was found between the groups at pre‐test, but at post‐test the experimental group exhibited greater accuracy in age estimation. Moreover, the experimental group increased its accuracy between the pre‐ and post‐tests. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

We investigated adults' ability to detect children's prepared and unprepared lies and truths. Furthermore, we examined children's strategies when lying. Thirty children (11–13 years) were interviewed about one self‐experienced and one invented event each. Half had prepared their statements, the other half not. Sixty adult observers assessed the veracity of 10 videotaped statements each. Overall deception detection accuracy (51.5%) was not better than chance. The adults showed higher accuracy for unprepared statements (56.6%), than prepared statements (46.1%). The adults reported to have used more verbal than nonverbal cues to deception, especially the Detail criterion. The most frequent verbal strategy reported by the children was to use real‐life components (e.g. own or others' experiences); the most frequent nonverbal strategy was to stay calm. Arguably, the low accuracy is due to adults' failure to see through the lying children's strategies. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

This research was designed to investigate Paulhus' communion management (CM) and self‐deceptive enhancement (SDE), socially desirable responding (SDR) scales as measures of general SDR, communal bias and agentic bias. The CM and SDE scales, as well as the Schwartz values survey (SVS), were administered to four samples drawn from different cultures and subcultures (N = 900). Participants completed the questionnaires in ‘honest’ and ‘fake good’ conditions. Although conceptions of which values were desirable varied strongly between samples and instructional sets, the CM scale was consistently related to general SDR and to communal bias. In contrast, the SDE scale was only related to general SDR. Contrary to expectations, neither scale could identify participants who ‘faked good’ under normal instructions.

Background
International studies indicate an increased incidence of substance abuse disorders among physicians. This article investigates specific variables in the work field and describes existing treatment programs.Patients and methods
In a cross-sectional study 107 physicians with and 468 without substance abuse disorders were compared. Two highly developed treatment programs in Germany and Canada are described.Results
The high work-load associated with the medical work environment leads to reduced performance and social isolation. Treatment programs for addicted physicians work with the concept of ?help before restriction“. The abstinence rate of the 5-year Canadian program is over 90%.Conclusions
As a form of prevention, medical students should be systematically informed about work-related stress in the medical profession. Structured treatment programs should be implemented nationwide. The expert team ?Risk of addiction in physicians“ of the German Addiction Foundation, whose members are authors of this article, may be a small step in this direction. 相似文献999.
Considering the fact that all psychic disturbances are emotional disturbances as well, we develop based on our research on the modular structure of the emotional system a systematisation of the disturbance-specific concatenation of these modules within the patient’s social relationships. Subsequently, we discuss treatment possibilities and contraindications for each clinical empirically validated constellation. We describe a fundamental mechanism of affect induction keeping the disturbances alive and transporting them to the next generation. We conclude in stating that treatment recommendations focusing on a standard algorithm of handling the emotions system fail because there is no general indication for such enterprises. 相似文献

Selectively retrieving a subset of previously studied material can cause forgetting of the unpracticed material. Such retrieval-induced forgetting is attributed to an inhibitory mechanism recruited to resolve interference among competing items. According to the inhibition-deficit hypothesis, older people experience a specific decline in inhibitory function and thus should show reduced retrieval-induced forgetting. However, the results of the two experiments reported here show the same amount of retrieval-induced forgetting in younger and older adults. These results indicate that retrieval inhibition is intact in older adults' episodic recall. The findings suggest that the common view of a general inhibitory deficit in older adults needs to be updated and that older adults show intact inhibition in some cognitive tasks and deficient inhibition in others. 相似文献
