Reaches, performed by 5 infants, recorded at 19 weeks of age and every third week thereafter until 31 weeks of age, were studied quantitatively. Earlier findings about action units were confirmed. At all ages studied, movements were structured into phases of acceleration and deceleration. Reaching trajectories were found to be relatively straight within these units and to change direction between them. It was also found that at all ages, there was generally one dominating transport unit in each reach. The structuring of reaching movements changed in four important ways during the period studied. First, the sequential structuring became more systematic with age, with the dominating transport unit beginning the movement. Second, the duration of the transport unit became longer and covered a larger proportion of the approach. Third, the number of action units decreased with age, approaching the two-phase structure of adult reaching. Finally, reaching trajectories became straighter with age. 相似文献

The effects of sex and personality traits on self-estimates of intelligence were examined in a sample of 302 Austrian adults (143 men, 159 women). Confirming previous research, men had higher self-estimates of logical and spatial abilities than did women, and these differences were partly explained in terms of women's higher Neuroticism scores. Neuroticism (negatively) and Openness (positively) accounted significantly for variances in self-estimates of spatial and logical intelligence. However, sex had stronger direct and indirect effects on self-estimates of intelligence. Sex and personality effects appear to be largely independent. Thus, being male, emotionally stable, and open to new experiences is likely to result in higher self-estimates of spatial and logical abilities. 相似文献

Hertzog et al. evaluated the statistical power of linear latent growth curve models (LGCMs) to detect individual differences in change, i.e., variances of latent slopes, as a function of sample size, number of longitudinal measurement occasions, and growth curve reliability. We extend this work by investigating the effect of the number of indicators per measurement occasion on power. We analytically demonstrate that the positive effect of multiple indicators on statistical power is inversely related to the relative magnitude of occasion‐specific latent residual variance and is independent of the specific model that constitutes the observed variables, in particular of other parameters in the LGCM. When designing a study, researchers have to consider trade‐offs of costs and benefits of different design features. We demonstrate how knowledge about power equivalent transformations between indicator measurement designs allows researchers to identify the most cost‐efficient research design for detecting parameters of interest. Finally, we integrate different formal results to exhibit the trade‐off between the number of measurement occasions and number of indicators per occasion for constant power in LGCMs. 相似文献

Power has been found to increase risk‐taking (Anderson & Galinsky, 2006 ) but this effect appears to be moderated by individual differences in power motivation (Maner, Gailliot, Butz, & Peruche, 2007 ). Among individuals high in power motivation, the experience of power leads to more conservative decisions. As testosterone is associated with the pursuit of power and status (Dabbs & Dabbs, 2000 ), we reasoned that high‐testosterone individuals primed with power might be similarly risk‐avoidant. Conversely, we hypothesized that high‐testosterone individuals primed with low power, would see risk‐taking as a vehicle for pursuing potential gains to their status and resources. We report findings from two experiments that are consistent with these predictions. In Experiment 1, higher testosterone males (as indicated by second–fourth digit ratio) showed greater risk‐taking when primed with low power. Experiment 2 replicated this effect and also showed that when primed with high power, higher testosterone males took fewer risks. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

We used data from a large, longitudinal study of children in the community, the NICHD Study of Early Child Care and Youth
Development, to examine how well earlier measures of delay capacity, inhibitory control, planning, and attention predicted
symptoms of attention deficit hyperactivity disorder (ADHD) assessed in third grade. Children with elevated symptoms of both
inattention and hyperactivity-impulsivity (n = 57) and with inattentive symptoms only (n = 80) were identified via mother and teacher reports using the “or” rule, as were children without significant symptoms (n = 790). Multinomial logistic regression analyses indicated that poorer performance on earlier measures of resistance to temptation,
delay of gratification, response inhibition, attention, and planning obtained from 36 months to 1st grade predicted membership
in the two symptom groups relative to the comparison group in 3rd grade, albeit with somewhat different patterns of predictors.
Controls for 36 month school readiness and externalizing symptoms indicated that these results were generally robust and not
an artifact of initial cognitive or behavioral differences. Implications for developmental models of ADHD are discussed.

ABSTRACT— Older adults express greater prejudice than younger adults, but it is not clear why. In a community-based sample, we found that older White adults demonstrated more racial prejudice on an implicit measure, the race Implicit Association Test, than did younger adults. Process-dissociation procedures indicated that this difference in implicit prejudice was due to older adults having less control of their automatic prejudicial associations rather than stronger automatic prejudicial associations. Furthermore, this age difference in control was mediated by age-related deficits in inhibitory ability. White participants showed stronger automatic prejudicial associations than did Black participants. 相似文献

Although research has focused on how service employees regulate their emotions, few studies have explored why they do so. In this article, we first described which kinds of motives for emotion regulation exist in customer interactions. Second, we investigated how the motives are related to four emotion regulation strategies. The application of an explorative approach resulted in a list of 10 motives, which could be classified into the three motive categories: pleasure, prevention, and instrumental. Hierarchical linear modelling of 421 reported service interactions from a diary study revealed that the motive categories were differently related to the emotion regulation strategies. Motives of the instrumental category were only significantly positively related to surface acting. Motives of the pleasure category were positively related to deep acting and automatic regulation as well as negatively related to surface acting and emotional deviance. Motives of the prevention category were positively related to deep acting, surface acting, and emotional deviance as well as negatively related to automatic regulation. These results can be used by organizations not only to enhance the motivation of employees towards emotion regulation, but also towards more authentic emotional expressions. 相似文献

In many countries in Western Europe today, religion is an important factor in public debates. Contrary to most expectations, religion has not vanished or even become subordinate under the influence of secularism. While this phenomenon has put the general theory of secularization under pressure, an alternative model for explaining the place of religion in Western Europe is only slowly taking shape. The present article is a contribution to this discussion. Making use of discourse analysis as it has been developed in the sociology of knowledge and in historiography, the article problematizes and transcends the secular–religious divide. It is argued that the entanglement of religious and secular discourses has produced new meanings and new realities since the rise of secularism in the eighteenth century. Four perspectives on the reconfiguration of the religious fields of discourse are introduced that have shaped contemporary religious landscapes in Western Europe. These perspectives are discussed with special attention to the situation in the Netherlands. 相似文献

The current paper introduces a novel feature of implicit association tests (IATs) by demonstrating their potential to change implicit attitudes. We assume that such changes are driven by associative learning mechanisms caused by carrying out an IAT task. Currently, evaluative conditioning appears to be the only widespread paradigm for changing implicit attitudes. An IAT task could provide an alternative. In two experiments, participants initially reacted to only one IAT task. Implicit preferences subsequently assessed with different implicit measures depended on the initial IAT task. This was shown for implicit self-esteem and for implicit attitudes towards well-known candy brands. Findings are discussed in relation to task-order effects in IATs. 相似文献
