Under many conditions auditory input interferes with visual processing, especially early in development. These interference effects are often more pronounced when the auditory input is unfamiliar than when the auditory input is familiar (e.g. human speech, pre‐familiarized sounds, etc.). The current study extends this research by examining how auditory input affects 8‐ and 14‐month‐olds’ performance on individuation tasks. The results of the current study indicate that both unfamiliar sounds and words interfered with infants’ performance on an individuation task, with cross‐modal interference effects being numerically stronger for unfamiliar sounds. The effects of auditory input on a variety of lexical tasks are discussed. 相似文献

Lay conceptions of personality change and continuity were examined in a sample of 112 undergraduates. Participants rated their personal change over 5 years (past or future), the change they perceived to be normative over 10-year age spans between 15 and 65, their beliefs about whether personality is fixed or malleable (“lay theories”) and their beliefs about the causes of personality change and continuity. Beliefs about normative personality change generally corresponded to research evidence on adult trajectories of the Big Five factors, with some age bias, whereas recalled and anticipated personal change tended to be more positive than these norms. Participants tended to endorse environmental causes more for personality change than for continuity. Lay theories were not consistently associated with these causal beliefs, or with beliefs about personal and normative change. 相似文献

Moral Conviction and Political Engagement 总被引:1,自引:0,他引:1
The 2004 presidential election led to considerable discussion about whether moral values motivated people to vote, and if so, whether it led to a conservative electoral advantage. The results of two studies—one conducted in the context of the 2000 presidential election, the other in the context of the 2004 presidential election—indicated that stronger moral convictions associated with candidates themselves and attitudes on issues of the day uniquely predicted self-reported voting behavior and intentions to vote even when controlling for a host of alternative explanations (e.g., attitude strength, strength of party identification). In addition, we found strong support for the hypothesis that moral convictions equally motivated political engagement for those on the political right and left and little support for the notion that a combination of morality and politics is something more characteristic of the political right than it is of the political left. 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

The integrity of cerebral white matter is critical for efficient cognitive functioning, but little is known regarding the
role of white matter integrity in age-related differences in cognition. Diffusion tensor imaging (DTI) measures the directional
displacement of molecular water and as a result can characterize the properties of white matter that combine to restrict diffusivity
in a spatially coherent manner. This review considers DTI studies of aging and their implications for understanding adult
age differences in cognitive performance. Decline in white matter integrity contributes to a disconnection among distributed
neural systems, with a consistent effect on perceptual speed and executive functioning. The relation between white matter
integrity and cognition varies across brain regions, with some evidence suggesting that age-related effects exhibit an anterior–posterior
gradient. With continued improvements in spatial resolution and integration with functional brain imaging, DTI holds considerable
promise, both for theories of cognitive aging and for translational application. 相似文献

A new illusion in which the apparent number of elements of two kinds is determined by their spatial arrangement is described. The illusion is such that one large cluster appears to contain more elements than several small clusters, clustering being determined by Gestalt principles. The illusion was found both in adults and in children of 8 years. 相似文献

Goal orientation: effects on backing up behavior, performance, efficacy, and commitment in teams 总被引:1,自引:0,他引:1
Porter CO 《The Journal of applied psychology》2005,90(4):811-818
The author examined the predictive validity of goal orientation in teams on both team process and outcome variables. Results indicate that when mean goal orientation scores were used as a way of describing team members' inputs, learning orientation was related to backing up behavior, efficacy, and commitment. The relationships between performance orientation and efficacy and commitment, however, were more complex and were clarified when task performance was also taken into account. Performance orientation had a negative effect on efficacy when task performance was low and a positive effect on commitment when task performance was high. The implications of these findings for theory and research on goal orientation in teams and team staffing are discussed. 相似文献

A list of gender-related and gender-neutral words for use in testing gender stereotyping and memory was created and evaluated.
Words were rated by samples of undergraduates at universities located in the northeast, southeast, and south-central United
States. A substantial list of masculine, feminine, and gender-neutral words was identified. These lists allow researchers
to construct large lists of gender-associated words while being able to control for extraneous variables, such as word frequency
and word length. In addition, the high reliability across the samples suggests that gender ratings are a fairly stable phenomenon.
Applications for this list are discussed. The word lists presented in Tables 1–3 and the raw data analyzed in this article
