To understand how individuals adapt to and anticipate each other in joint tasks, we employ a bidirectional delay–coupled dynamical system that allows for mutual adaptation and anticipation. In delay–coupled systems, anticipation is achieved when one system compares its own time‐delayed behavior, which implicitly includes past information about the other system’s behavior, with the other system’s instantaneous behavior. Applied to joint music performance, the model allows each system to adapt its behavior to the dynamics of the other. Model predictions of asynchrony between two simultaneously produced musical voices were compared with duet pianists’ behavior; each partner performed one voice while auditory feedback perturbations occurred at unpredictable times during live performance. As the model predicted, when auditory feedback from one musical voice was removed, the asynchrony changed: The pianist’s voice that was removed anticipated (preceded) the actions of their partner. When the auditory feedback returned and both musicians could hear each other, they rapidly returned to baseline levels of asynchrony. To understand how the pianists anticipated each other, their performances were fitted by the model to examine change in model parameters (coupling strength, time‐delay). When auditory feedback for one or both voices was removed, the fits showed the expected decrease in coupling strength and time‐delay between the systems. When feedback about the voice(s) returned, the coupling strength and time‐delay returned to baseline. These findings support the idea that when people perform actions together, they do so as a coupled bidirectional anticipatory system. 相似文献

Are different responses differentially associable with their consequences? An overshadowing design was used to try to answer this question for three responses previously studied in golden hamsters. In Experiment I, scrabbling was rapidly suppressed by electric shock punishment, and it overshadowed a tone which occurred between scrabbling and shock. In Experiment II, no evidence of response-shock association was obtained when open rearing was the punished response, and open rearing did not overshadow the tone. Punishment had some effect on face washing, but there was no statistically significant overshadowing with this response. These results are consistent with the idea that differences in punishment suppression among these three responses have an associative basis. They also demonstrate the usefulness of a novel paradigm for studying “preparedness” of response-reinforcer associations. 相似文献

Children's perception of scale and contour in melodies was investigated in five studies. Experimental tasks included judging transposed renditions of melodies (Studies 1 and 3), discriminating between transposed renditions of a melody (Study 2), judging contour-preserving transformations of melodies (Study 4), and judging similarity to a familiar target melody of transformations preserving rhythm or rhythm and contour (Study 5). The first and second studies showed that young children detect key transposition changes even in familiar melodies and they perceive similarity over key transpositions even in unfamiliar melodies. Young children also are sensitive to melodic contour over transformations that preserve it (Study 5), yet they distinguish spontaneously between melodies with the same contour and different intervals (Study 4). The key distance effect reported in the literature did not occur in the tasks of this investigation (Studies 1 and 3), and it may be apparent only for melodies shorter or more impoverished than those used here. 相似文献

The views that women and girls hold about themselves contribute to the segregation of women in the labour market. Women's Training Roadshows are an example of initiatives aimed at 'cultural interruption', in that they attempt to challenge occupational stereotypes. This paper evaluates the Cardiff Women's Roadshow from the schoolgirls' perspective and discusses the implications of the findings for careers guidance at school level. 相似文献

Computer Communication and Organizational Commitment: Tracing the Relationship in a City Government 总被引:2,自引:0,他引:2
Various theories and management policies suggest that there should be a positive relationship between communication and commitment to the organization. However, support for that relationship remains equivocal. We report the results of a questionnaire on communication and commitment filled out by 376 employees of a mid-sized city government. They were asked about the mode and frequency of their communications within the organization and about their commitment to the city government. Consistent with our hypotheses about the nature of computer-mediated communication, use of computer mail and bulletin boards predicted organizational commitment, but use of the telephone and paper modes of communication did not. In addition, those most likely to benefit from the immediacy and memory of computer communication—shift workers—evidenced a stronger relationship between computer mail use and commitment than did regular employees. Two mechanisms for mediating the relationship between communication and commitment were evaluated. Evidence supports active participation in communication as a mediating mechanism in the relationship between communication and commitment. The informational value of communication does not appear to be important in this regard. 相似文献
