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

Most previous research found negative effects on learning outcomes when interesting but irrelevant information (i.e., seductive details) is added to an instruction. To what degree such effects are bound to specific conditions is in the focus of this special issue. Specifically, 11 empirical studies are reported within this special issue. They all address the topic of seductive details in learning and instruction by focusing either on cognitive moderators (e.g., working memory capacity and current beliefs) or on noncognitive moderators (e.g., arousal and affect) of the seductive details effect. Taken together, results from the empirical studies hint towards new moderators and suggest that the negative effects of seductive details on learning outcomes may be smaller than expected based on previous research. 相似文献

Research has shown that greater stress responses predict worse sleep and that the quality of one's current romantic relationship predicts one's sleep. Despite these established links, research has not examined connections between ongoing patterns of interpersonal experiences and competencies (relationship effectiveness) and stress exposure on sleep. Participants in the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) completed measures assessing relationship effectiveness and stress exposure at ages 23 and 32 years, as well as sleep quality/duration at age 37 years. Analyses demonstrate that relationship effectiveness at age 23 years positively predicts sleep quality—but not sleep duration—at age 37 years via reduced stress exposure at age 32 years. These findings highlight the effects of relationship effectiveness and stress exposure across early to middle adulthood on sleep. 相似文献

Online review helpfulness ratings are an important indicator of the impact of online reviews. Often times, helpfulness is explained in terms of observable qualities of online reviews that predict helpfulness ratings. This research proposes that focusing on the psychological processes that underlie helpfulness voting informs a better understanding of what shapes review helpfulness ratings. Specifically, because goal orientation influences information processing, consumers’ regulatory orientation interacts with review valence to determine review helpfulness. When review valence and regulatory orientation match, consumers are more likely to express helpfulness through voting. The findings show that this effect occurs at least in part because matching review valence and regulatory orientation instills feelings of gratitude towards the reviewer. As a consequence, consumers are more likely to reward the reviewer with a helpfulness vote to express their feeling of gratitude through actions. However, when reviewers actively state expectations of reciprocal behavior by readers, gratitude is reduced and so is the likelihood that a review receives a helpfulness vote. Evidence from five studies using review data and online experiments show support for these effects. 相似文献

Using data from the Austrian National Election Study (Study 1) and the American National Election Study (Study 2), this research investigated the role of right-wing authoritarianism (RWA) in shaping attitudes toward governmental action related to the redistribution of wealth. We show that RWA is a relevant variable in explaining attitudes toward redistribution policies, and that the association between RWA and redistribution attitudes is moderated by political sophistication. RWA was associated with opposition to redistribution policies among individuals high in political sophistication, while among individuals low in political sophistication, RWA was either associated with support for redistribution policies (Study 1) or unrelated to redistribution attitudes (Study 2). Results suggest that exposure to the political discourse in a society affects how psychological needs and motives are related to preferences regarding the redistribution of wealth through the government. 相似文献
