The hypotheses of this investigation were based on conceiving of facial mimicry reactions in face-to-face interactions as an early automatic component in the process of emotional empathy. Differences between individuals high and low in emotional empathy were investigated. The parameters compared were facial mimicry reactions, as represented by electromyographic (EMG) activity, when individuals were exposed to pictures of angry or happy faces. The present study distinguished between spontaneous facial reactions and facial expressions associated with more controlled or modulated emotions at different information processing levels, first at a preattentive level and then consecutively at more consciously controlled levels: 61 participants were exposed to pictures at three different exposure times (17, 56, and 2350 ms). A significant difference in facial mimicry reactions between high- and low-empathy participants emerged at short exposure times (56 ms), representing automatic, spontaneous reactions, with high-empathy participants showing a significant mimicking reaction. The low-empathy participants did not display mimicking at any exposure time. On the contrary, the low-empathy participants showed, in response to angry faces, a tendency to an elevated activation in the cheek region, which often is associated with smiling.  相似文献

Model misspecifications may have a systematic effect on parameters, causing biases in their estimates. In the application of structural equation models, every interesting model is fallible. When simultaneously evaluating a model, it is of interest to study whether all parameters are affected by a misspecification. This paper provides three procedures for evaluating such an effect: (1) analyzing the path, (2) using a functional relationship, and (3) using a significance test. Analyzing the path is illustrated through a confirmatory factor model. This method is ad hoc but intuitive. A more rigorous approach is built upon the concept of orthogonality of two sets of parameters. When parameter a is orthogonal to parameter b, omitting parameter b will not affect the estimation of parameter a. The functional relationship of two sets of parameters is used to check their orthogonality. The distribution of the difference between estimates based on different models is obtained, which provides a Hausman–like way to check significant parameter differences that are due to biases. Examples illustrate that these procedures can provide valuable information on identifying parameter estimates that are systematically affected by a model misspecification.  相似文献

This longitudinal study of forty‐four families explored fathers’ as compared to mothers’ specific contribution to their children's attachment representation at ages 6, 10, and 16 years. In toddlerhood, fathers’ and mothers’ play sensitivity was evaluated with a new assessment, the sensitive and challenging interactive play scale (SCIP). Fathers’ SCIP scores were predicted by fathers’ caregiving quality during the first year, were highly consistent across 4 years, and were closely linked to the fathers’ own internal working model of attachment. Qualities of attachment as assessed in the Strange Situation to both parents were antecedents for children's attachment security in the Separation Anxiety Test at age 6. Fathers’ play sensitivity and infant–mother quality of attachment predicted children's internal working model of attachment at age 10, but not vice versa. Dimensions of adolescents’ attachment representations were predicted by fathers’ play sensitivity only. The results confirmed our main assumption that fathers’ play sensitivity is a better predictor of the child's long‐term attachment representation than the early infant–father security of attachment. The ecological validity of measuring fathers’ sensitive and challenging interactive play behavior as compared to infant proximity seeking in times of distress is highlighted. Findings are discussed with respect to a wider view on attachment in that both parents shape their children's psychological security but each in his or her unique way.  相似文献

This study explores the similarity of touch behavior and touch attitudes among dating and married couples. Touch behavior showed a strong matching effect for seriously dating and married couples. Z-tests revealed that correlations between relational partners were significantly stronger for marrieds than for serious or casual daters. Results for attitudes concerning touch showed a statistically significant but weak relationship between dyadic partners though the correlation strengthened in closer relationships. As was the case in previous studies, results showed that women reported less positive attitudes toward opposite-sex touch than men. A linear contrast in proportions demonstrated that men initiated touch significantly more in casual romantic relationships, but women initiated touch more in married relationships. Together, these data suggest that patterns of matching may vary as a function of relationship stage, while patterns of touch initiation may vary as a function of both relationship stage and sex.She will be at Pennsylvania State University in the Fall.An earlier version of this paper was presented at the 1991 meeting of the Western States Communication Association, Phoenix, AZ.

This article explores how development programming in rural poverty and the environment can work with indigenous peoples. It draws on research conducted in Asia and Latin America to suggest how indigeneity can be understood as specific kinds of marginalisation intersecting with self‐identification and recognition as indigenous. Current obstacles to effective engagement with indigenous peoples are outlined, and suggestions are offered for pro‐actively addressing their experience. Two critical areas where there are opportunities for donors to support indigenous peoples' priorities include ‘FPIC’ (Free Prior and Informed Consent) and a careful consideration of the implications of niche‐market engagement.  相似文献
