Among executive functions (EFs), research has highlighted specific inhibition difficulties in preterm children. The present paper reviews and classifies the studies that assessed response inhibition and interference control abilities in preterm children and adolescents aged 3 to 16 years. Most behavioral studies agree on a developmental delay at early school age in inhibition abilities and a catch-up before adolescence, with lesser response inhibition difficulties at pre-adolescence. However, persisting interference control difficulties have been reported into early adulthood. These results are discussed, along with functional magnetic resonance imaging (fMRI) findings. Finally, this paper outlines methodological issues that need to be overcome in order to define the developmental trajectory of inhibition abilities in the preterm population. 相似文献

A measure of men's attitudes toward their body (MBAS) was developed and evaluated via three independent samples of college men. In Studies 1 and 2, factor analyses determined and cross-validated the MBAS's underlying structure. Three factors emerged from the items: muscularity, low body fat, and height. Studies 1 and 2 provided construct (i.e., convergent, concurrent, and discriminant) validity evidence for the MBAS total scale and subscales; they were related or not related as expected to drive for muscularity, body esteem, internalization of the muscular ideal, pressures for muscularity, pressures for thinness, self-esteem, body comparison, eating disorder symptomatology, and impression management. Study 3 revealed that the MBAS total score and subscale scores were stable over a 2-week period. The internal consistency reliabilities for the total score and subscale scores were high across all three studies. The MBAS should prove useful for researchers and clinicians interested in men's body image assessment. 相似文献

There is an increasing interest in the complexity of mainstream communication education, and in the management of today's Global Media Organizations. Real world systems in communication processes cannot be completely designed, controlled, understood, or predicted, even by the sciences of complexity, but they are more effectively understood and explained as complex systems. I explore complexity in this article, analyzing the new paradigm of Agenda-Setting of today's New Media and Communication. 相似文献

This study evaluated the degree to which an 8-subtest short form of the Wechsler Intelligence Scale for Children—Fourth Edition would yield acceptable estimates of the long-form Full-Scale IQ index while clarifying the underlying factor structure in a sample of 100 children and adolescents with traumatic brain injury. The short-form Full-Scale IQ had sufficient (i.e., at least two thirds) nonerror covariance with its full-length counterpart. In addition, a sufficient proportion (i.e., > 80%) of these short-form estimates fell within the 90% confidence interval of the respective full-length scores. Importantly, the elimination of 2 subtests, and in particular the Picture Concepts subtest, resulted in a factor structure where each remaining subtest was fairly specifically associated with its intended scale. It is concluded that this short form can be used clinically in children with traumatic brain injury without sacrificing reliability and with more straightforward interpretability at the level of the factor index scores. 相似文献

Global leadership is the pivotal point for appropriate policies and action to ensure human survival, but a fast-changing world requires a learning leadership. How can potential and serving leaders acquire the necessary skills, abilities, and attributes for them to recognize and address the threats and challenges to our survival in the contemporary world? Serving leaders have little time for formal learning. They learn on the job through reciprocal peer interaction and transactional relationships with their followers. But the global aspect demands another dimension, cybernetic learning, within which an awareness of global ethics is central. 相似文献

The growth of the modern corporation from local and nationally centered origins to the multinational and then the global level is traced on the one hand to global flows of matter, energy, and information, and on the other to the geographic and political constraints exercised by nation-states. The emergence of the global corporation follows basic laws of evolution applicable to all complex systems, whether in nature or in society. Thus the global corporation is a new but not an anomalous phenomenon on the stage of history. 相似文献

In this concluding article we further reflect on relational readings of organizational learning and how they can contribute to organization studies and organizing practices. As has been seen, the root metaphor of “organizational learning” takes a variety of forms. These include “product-oriented” pictures such as learning curves, strategy, and business processes, and the generative metaphor of organizational learning as conversations-for-new-possibilities. This special issue highlights the contribution of learning-as-conversations, especially in those organizational instances where the organizing is “in-the-making” and where the creation of a transitional space can be a new meeting ground for participants. In an increasingly globalized world we are more and more in need of the ability to construct such transitional and possibility-enabling practices. It can be a task of work and organizational psychology to contribute ideas and practices for this endeavour. 相似文献

ABSTRACT Objective: Few studies have addressed whether the metabolic syndrome (MetS) and its individual components are associated with cognitive function in middle-aged and older populations, as well as whether specific areas of cognition are more affected than others. We examined the cross-sectional association between MetS and six areas of cognitive function in healthy cognitively intact adults without diabetes (n?=?853, mean age 61 years) randomized in two intervention trials. Methods: The National Cholesterol Education Program (NCEP) criteria were used to identify subjects with MetS. Cognitive function was assessed with a neuropsychological battery. A principal components analysis was used to extract five uncorrelated factors interpreted to represent five areas of cognition, and a measure of global cognition was calculated. Results: MetS was weakly but non-significantly associated with lower verbal learning (β?=??.14 [SE(β)?=?0.09], p?=?.15). As the number of MetS criteria increased, scores on global cognition (p trend?=?.01), verbal learning (p trend?=?.06) and semantic memory (p trend?=?.04) decreased. Hypertension was the only MetS risk factor that was independently correlated with lower verbal learning (β?=??.17 [SE(β) =?0.08], p?=?.04), semantic memory (β?=??.26 [SE(β)?=?0.08], p?=?.001) and global cognition (β?=??.15 [SE(β)?=?0.07], p?=?.04). Conclusion: This study adds to the evidence of an association between MetS and lower cognitive function among healthy middle-aged and older adults without CVD and diabetes, as well as confirms the correlation between hypertension and lower cognition. 相似文献

ABSTRACT It has been well documented that education influences the individual's performance on category fluency tasks but it is still unclear how this effect may differ across the different types of category tasks (i.e., animals, fruits, vegetables and clothing). This study aims (1) to analyze the effect of the level of education on four different types of category fluency tasks among elder Hispanic Americans and (2) to provide normative information on a population with different education levels that was previously screened for neurological and psychiatric conditions. In addition this study examines the semantic strategies used by these individuals to complete the fluency tasks. The sample included 105 healthy Hispanic individuals (age 55–98; 29 males and 76 females) divided into three education groups (<6, 6–11 and >11 years of education). Results showed that after controlling for age and gender, education has a main effect and is a strong predictor of performance in verbal fluency for the categories animals and clothing with increasing educational attainment being associated with higher category fluency scores and with more switches between categories. These findings suggest that the category fruit is less influenced by level of education than the other three semantic categories and may be a more appropriate test across different educational groups. Results from this study provide a reference for clinicians assessing verbal fluency in Spanish speaking populations. 相似文献

ABSTRACT Episodic memory is the first and most severely affected cognitive domain in Alzheimer's disease (AD), and it is also the key early marker in prodromal stages including amnestic mild cognitive impairment (MCI). The relative ability of memory tests to discriminate between MCI and normal aging has not been well characterized. We compared the classification value of widely used verbal memory tests in distinguishing healthy older adults (n = 51) from those with MCI (n = 38). Univariate logistic regression indicated that the total learning score from the California Verbal Learning Test-II (CVLT-II) ranked highest in terms of distinguishing MCI from normal aging (sensitivity = 90.2; specificity = 84.2). Inclusion of the delayed recall condition of a story memory task (i.e., WMS-III Logical Memory, Story A) enhanced the overall accuracy of classification (sensitivity = 92.2; specificity = 94.7). Combining Logical Memory recognition and CVLT-II long delay best predicted progression from MCI to AD over a 4-year period (accurate classification = 87.5%). Learning across multiple trials may provide the most sensitive index for initial diagnosis of MCI, but inclusion of additional variables may enhance overall accuracy and may represent the optimal strategy for identifying individuals most likely to progress to dementia. 相似文献
