Two experiments provide convergent evidence for the hypothesis that listeners interpret chords in terms of their harmonic functions in a system of interrelated keys. The perceived associations between chords undergo significant changes depending on the broader tonal framework in which they are embedded. Three independent context effects are identified, and their magnitude is found to be a systematic function of the distance between the context key and the key lot keys) of which the chords are members. In the first experiment, listeners rate how musically related one chord is to a second chord; the chords are those that function within two maximally distant major keys (C major and F# major). All possible chord pairs from this set are presented in each of three context keys: G major which is close to C major and distant from F# major), A major (which is moderately distant from both C major and F# major), and B major (which is close to F# major and distant from C major). The second experiment measures recognition memory for the same chords embedded in tonal sequences in C, G, A, or B major keys, or random sequences. In the two experiments, the distance between the context key and the key of the chords on the circle-of-fifths affects: (1) the probability that a repeated chord is correctly recognized, (2) the strength of association between chords from the same key measured in terms of both confusion errors and direct relatedness judgments, and (3) asymmetries in confusion errors and relatedness judgments when the chords are in different keys. Perceived harmonic relations are thus found to be strongly context dependent, but the context effects are lawful functions of interkey distance. We conclude that listeners possess a highly articulated system of knowledge about the harmonic functions of chords in musical keys and an appreciation of musical structure at the level of abstract tonal centers. 相似文献

Direct biofeedback of blood pressure was compared with frontal EMG biofeedback and with self-instructed relaxation for the treatment of essential hypertension in a controlled group outcome study. Patients were followed up for four months after the end of treatment. Generalization of treatment effects was assessed through pre- and posttreatment measurements of blood pressure under clinical conditions in a physician's office. There were no significant reductions in diastolic blood pressure. The systolic blood pressure (SBP) of the patients receiving blood pressure biofeedback decreased 8.1 mm mercury (p = 0.07) and the SBP of the patients in the relaxation condition decreased 9.5 mm mercury (p = 0.05). In the generalization measures, there were significant reductions in SBP for the relaxation group. The results are discussed in terms of the general lack of replicability within the area of biofeedback treatment of hypertension. 相似文献

The interpersonal help-giving behaviors of 90 hairdressers were explored in depth in an interview study. On the average, hairdressers saw 55 customers a week, and talked 25 minutes with each. About one-third of the talking time concerned clients' moderate to serious personal problems--particularly problems with children, physical health, marriage, depression, and anxiety. Hairdressers reported that offering sympathy and support, being lighthearted, just listening, and presenting alternatives were among their most frequent response strategies. Although they often enjoyed fielding clients' personal problems, at times they felt perplexed by them. Hairdressers perceived listening to customers' interpersonal problems to be an important part of their everyday function and expressed a need for professional inputs in that domain. 相似文献

A handedness questionnaire was administered to 446 stutterers and a control group. No significant male/female or stutterer/control effects were found, although both males and stutterers tended to be less right handed. The slight sex effect in handedness is consistent with previously reported studies and with cerebral structural and functional asymmetries. 相似文献
