Nonverbal expectancy violations and conversational involvement 总被引:1,自引:0,他引:1

A central feature of nonverbal expectancy violations theory is that unexpected behaviors trigger a cognitive-affective appraisal of such behavior, leading to a valencing of the behavior(s) as positive or negative. It has been proposed that communicator reward mediates the interpretation and evaluation of such violations but may be more important when the violative act is ambiguous in meaning than when it is not. Unclear is whether nonverbal behavioral composites introduce greater or less equivocality of interpretation. Two experiments employing multi-cue conversational involvement violations addressed this issue. In the first, dyads (N=51) engaged in a 10-minute baseline interview, after which participants rated each other on several measures of reward valence. One randomly selected member then served as a confederate interviewee during a second interview and either significantly increased or decreased involvement. In the second experiment, reward was manipulated as physical attractiveness, status, and task expertise. Dyads (N = 60) engaged in prolonged problem-solving discussions during which the confederates either committed an involvement violation or not. In both experiments, the involvement changes were sufficiently unexpected, arousing, and distracting to qualify as violations of expectations. Analysis of message interpretations indicated that (1) relative to normal involvement levels, increased nonverbal involvement was interpreted as most immediate/affectionate, receptive, similar, dominant, and composed, and decreased involvement as least so, and (2) reward mediated only the interpretation of formality. High involvement violations in turn produced greater attraction, credibility, and persuasiveness than low involvement violations for high as well as low-reward communicators, as predicted.where Joe Walther and Jim Baesler are doctoral students. An earlier version of this paper was presented to the annual meeting of the International Communication Association, New Orleans, May 1988. 相似文献

Two of the most striking characteristics of contraceptive practice in the world today are the wide variation in patterns of use across countries and the tendency of the distribution of use by method to persist or narrow, even as new methods become available. The argument advanced in this article is that the disposition to commit to a reduced range of methods results from positive feedback in the process of contraceptive choice, and follows the logic of path dependence. The positive feedback derives, in large part, from social interaction among both the providers and the users of contraceptive methods. The persistence of outmoded contraceptive regimes is illustrated with the experience of Mexico and Brazil. In each case, it is argued that the conditions, events, and policies in the early stage of the adoption process have had a determinant bearing on the contraceptive practice prevailing in the late 1990s. 相似文献

Randomization is a puzzle for Bayesians. The intuitive need for randomization is clear, but there is a standard result that Bayesians need not randomize. In this paper we propose a model in which randomization is a strictly optimal procedure. The most important aspect of our model is that there are several parties who make different decisions and observe different data. The result also sheds light on the ethical considerations involving randomization in a clinical trial. 相似文献

A Cross‐National Investigation of the Relationship Between Infant Walking and Language Development 下载免费PDF全文
The acquisition of walking has recently been linked with infant language development (Walle & Campos, 2014). If this relation reflects the consequence of an epigenetic event, then it should be present regardless of when the infant typically begins to walk, the infant's culture, and the infant's native language. This study sought to replicate the previously reported link between walking and language development in American infants and investigate whether this relation exists cross‐nationally in typically developing Chinese infants exposed to Mandarin. Urban Chinese infants not only provide a distinct linguistic and cultural population in which to study this relation but also typically begin walking approximately 6 weeks later than American infants. Our results demonstrated that (1) walking infants in both the American and Chinese samples had greater receptive and productive vocabularies than same‐aged crawling infants, (2) differences between crawling and walking infants were proportionally similar in each sample, and (3) the walking‐language relation was present for both noun and non‐noun vocabularies. These findings provide further support of a relation between infant walking onset and language development, independent of age. Avenues for future research of the processes involved in this relation, as well as additional populations of interest to investigate, are discussed. 相似文献

Traditionnellement, la littérature sur le développement consacrée aux marchés du travail d'Amérique latine s'est concentrée sur le nombre d'emplois et la productivité. Mais, étant donné la persistance d'une forte proportion d'emplois informels ou précaires, pour que l'analyse ait du sens, il faut aussi considérer des implications du statut professionnel sur la qualité de l'emploi. Partant d'observations faites ces dernières décennies, les auteurs concluent que la plupart des aspects de cette qualité – protection sociale comprise – dépendent de la signature d'un contrat écrit. Ce constat les conduit à formuler quelques suggestions pour stabiliser l'emploi formel et assurer un financement suffisant de la protection sociale. 相似文献

Historically, the development literature concerned with Latin American labour markets has focused on job numbers and productivity. But given the persistence of large shares of informal and now otherwise precarious employment, the authors argue that meaningful analysis also requires consideration of the implications of occupational status for the quality of employment. Based on empirical evidence from recent decades, they conclude that most dimensions of this concept – including social protection – depend on the conclusion of a written contract of employment. This finding leads them to outline policy options for stabilizing formal employment and securing adequate funding for social protection. 相似文献
