Seven experiments explored the time course of recognition of brief novel melodies. In a continuous-running-memory task, subjects recognized melodic transpositions following delays up to 2.0 min. The delays were either empty or filled with other melodies. Test items included exact transpositions (T), same-contour lures (SC) with altered pitch intervals, and different-contour lures (DC). DCs differed from Ts in the pattern of ups and downs of pitch. With this design, we assessed subjects’ discrimination of detailed changes in pitch intervals (T/SC discrimination) as well as their discrimination of contour changes (T/DC). We used both artificial and “real” melodies. Artificial melodies differed in conformity to a musical key, being tonal or atonal. After empty delays, T/DC discrimination was superior to T/SC discrimination. Surprisingly, after filled delays, T/SC discrimination was superior to T/DC. When only filled delays were tested, T/SC discrimination did not decline over the longest delays. T/DC performance declined more than did T/SC performance across both empty and filled delays. Tonality was an important factor only for T/SC discrimination after filled delays. T/DC performance was better with rhythmically intact folk melodies than with artificial isochronous melodies. Although T/SC performance improved over filled delays, it did not overtake T/DC performance. These results suggest that (1) contour and pitch-interval information make different contributions to recognition, with contour dominating performance after brief empty delays and pitch intervals dominating after longer filled delays; (2) a coherent tonality facilitates the encoding of pitch-interval patterns of melodies; and (3) the rich melodic—rhythmic contours of real melodies facilitate T/DC discrimination. These results are discussed in terms of automatic and controlled processing of melodic information. 相似文献

In a continuous-running-memory task, subjects heard novel seven-note melodies that were tested after delays of 11 sec (empty) or 39 sec (filled). Test items were transposed to new pitch levels (to moderately distant keys in the musical sense) and included exact transpositions (targets), same-contour lures with altered pitch intervals, and new-contour lures. Melodies differed in tonal strength (degree of conformity to a musical key) and were tonally strong, tonally weak, or atonal. False alarms to same-contour lures decreased over the longer delay period, but only for tonal stimuli. In agreement with previous studies, discrimination of detailed changes in pitch intervals improved with increased delay, whereas discrimination of more global contour information declined, again only for tonal stimuli. These results suggest that poor short-delay performance in rejecting same-contour lures arises from confusion that is based on the similarity of tonality between standard stimuli and lures. If a test item has the same contour and a similar tonality to a just-presented item, subjects tend to accept it. After a delay filled with melodies in other tonalities, the salience of key information recedes, and subjects base their judgments on more detailed pattern information (namely, exact pitch intervals). The fact that tonality affects judgments of melodic contour indicates that contour is not an entirely separable feature of melodies but rather that a melody with its contour constitutes an integrated perceptual whole. 相似文献

This paper describes the development of the training programme offered at the Family Institute in Cardiff and presents the results of a retrospective survey reflecting the 'consumers' views of the programme. Questionnaires were sent to all students who had trained at the Institute between 1972 and 1977, to elicit information about their views of the placement, as well as their post-qualifying experience, activities and interest in family therapy. A briefer preliminary report has been published earlier (Dowling and Seligman, 1980). 相似文献

Splitting up the familiar tune “Yankee Doodle” by placing successive notes in different octaves makes it very difficult to recognize. The present experiments generalize this finding to more than one familiar tune and to presentation by actual musical instruments. Tunes differ in the degree to which their recognizability is affected by scrambling into different octaves, but recognition of all 10 tunes investigated was substantially diminished by the distortion. Increasing pitch proximity of temporally adjacent notes by leaving pairs or triples of successive notes intact within the same octave increases recognizability of at least some scrambled tunes. Leaving the melodic contour (the pattern of ups and downs) intact while splitting up the melody increases recognizability for subjects informed of the preservation of contour, though recognition is still worse than for undistorted versions. 相似文献

This study was designed to investigate whether the neuropsychological correlates of the symptom dimensions of schizophrenia vary with the clinical state in patients followed from the acute to stable the phase of the illness. Fifteen patients were assessed for symptoms (SAPS-SANS) and undergone a complete neuropsychological assessment at two sessions. The first session (S1) was carried out within six days after admission, i.e., acute phase and the second (S2) at least two month after hospitalization, i.e., stable phase. The data were analyzed using stepwise regression models in which neuropsychological scores were in entered to predict each dimensional score. This analysis was applied on the S1 and S2 data as well as on the S2-S1 difference to assess the neuropsychological predictors of clinical changes. Generally, the results replicate the previous associations between neuropsychological and dimensional measures found in stable patients. In addition, this study shows if each dimension appears to rely on a key structure, symptom variations seems to involve changes in the spread of the dysfunction and/or changes in the connectivity between the key and other regions. The results also suggest that functional changes related to some symptoms dimensions occur to compensate for the dysfunction associated with other symptoms. 相似文献

Emerging adulthood is an important period in the development of one's identity and autonomy. The ways in which identity and autonomy are viewed by emerging adults and how they impact quality of life (QoL) in individuals with early-onset neuromuscular conditions is not yet known. This study focused on understanding and exploring relationships between self-perceptions of emerging adulthood, autonomy, and QoL. Five previously validated measures were incorporated into an online survey and distributed to young adults with early-onset neuromuscular conditions and unaffected controls. Topics explored included individuals' views regarding their overall QoL, disease-specific QoL, components of emerging adulthood, and autonomy. We found that a sense of higher disease impact was associated with a lower Overall General QoL. Additionally, perceptions of key autonomy factors "negativity" and "instability" were uniquely associated with Overall General QoL in the case group as compared to controls, whereas "attitudinal autonomy" (attaining the ability to plan and follow through with goals) was important to this age group regardless of health status. The specific factors of emerging adulthood and autonomy that were significantly correlated with Overall General QoL can be used for developing targeted counseling and interventions to improve QoL for individuals and their families. 相似文献

Preventive interventions have historically focused on reducing risk factors for psychological difficulties. Recent research has found that prevention programs are more effective when they enhance strengths, rather than merely reduce risk factors. An increased focus on strengths is consistent with a positive psychology perspective. In fact, hope has been found to be a central human strength in the positive psychology literature. Hope is associated with better adjustment, lower anxiety, lower depression, greater academic performance, and greater athletic achievement. In addition, individuals with high hope are able to respond more adaptively after traumatic events and physical illnesses. Intervention studies have shown that hope can be increased in individuals, and hope has been shown to predict more positive outcomes in psychotherapy. Future directions for research are outlined, including investigating hope as a preventive intervention for members of stigmatized groups, including ethnic minorities and lesbian, gay, and bisexual individuals. 相似文献
