The purpose of this study was to investigate coaches’ perceptions on the impact of a coach training program designed to promote youth developmental outcomes. Participants were coaches of youth sport teams. Multiple methods were used to collect data. Coaches reported many benefits for themselves, their athletes, and their teams. They reported an increase in knowledge and a better understanding of their players. Participants perceived that the activities promoted cohesion and communication, while also contributing to the development of athlete competence, confidence, connection, and character/caring. The results provide guidance for creating and delivering coach training programs designed to promote youth developmental outcomes. 相似文献

预设路径模型(Fixed-links modeling)是在结构方程模型框架下发展出的用于分析心理学实验数据的统计模型。该类模型的主要特征是根据前期理论基础和实验设计,通过预先设定模型中显变量与潜变量之间的因素载荷矩阵实现对显变量方差的拆分。因素载荷矩阵的设定主要基于实验水平与所表征的心理过程之间的关系,选取相应函数来表征不同实验水平之间的变化趋势。该模型在表征工作记忆、注意和学习的内部加工过程及揭示不同认知过程的具体联系中发挥了重要作用。 相似文献

The relationship between attention and general intelligence was investigated considering the different types of attention: alertness, sustained attention, focused attention, attentional switching, divided attention, attention according to the supervisory attentional system, attention as inhibition, spatial attention, attention as planning, interference, attention as arousal, and attention according to the assessment tradition. In a sample of 197 participants the relationship of attention and intelligence was investigated by means of structural equation modeling. The results revealed that each type of attention was substantially related to intelligence on the latent level. Furthermore, a high degree of overlap in predicting intelligence was observed for the various types of attention. Comprehensive models based on resources theory and Posner's dimensions were also investigated. The best model of the relationship between attention and intelligence included two first-order and one second-order latent variables of attention and one of intelligence. It predicted 32% of the variance of intelligence. 相似文献

In two experiments, the contributions of memory and attention processes to the cognitive abilities of reasoning and perceptual speed were investigated. Two measures of speed of information retrieval from long-term and short-term memory (Posner paradigm, Sternberg paradigm) and two attention measures (continuous attention test, attention switching test) were included in the first experiment (N = 220). The memory tests led to correlations with the measures of cognitive abilities, whereas the attention test did not. The same tests as well as one additional memory test and one attention test (working memory test, test of covert orientation) were administered in the second experiment (N = 116). Again, the memory tests led to the larger correlations with the measures of cognitive abilities. Two components were obtained in components analysis, of which the first was characterized by high loadings of the memory tests and the second by high loadings of the attention tests. Only the memory component contributed to the prediction of cognitive abilities. 相似文献

An investigation of the cognitive bias observed in optimism and the influence of optimism on psychological well-being was conducted. The cognitive bias was assumed to be related to the repressive style of information processing, represented by the trait scale of the State-Trait Anxiety Inventory and the Social Desirability scale. Optimism and well-being were measured by the Life Orientation Test and the Social Optimism scale as well as by the Life Satisfaction and Depression scales, respectively. These scales were applied to a sample of 200 individuals. Trait Anxiety and Social Desirability led to a high multiple correlation with the Life Orientation Test (R = .54) and a moderate multiple correlation with the Social Optimism scale (R = .30). Higher correlations were obtained for the expectation of a positive than of a negative future. Both the Life Orientation Test and the Social Optimism scale contributed to the high multiple correlation with psychological well-being (R = .52). 相似文献

The present study provides a new account of how fluid intelligence influences
academic performance. In this account a complex learning component of fluid
intelligence tests is proposed to play a major role in predicting academic
performance. A sample of 2, 277 secondary school students completed two
reasoning tests that were assumed to represent fluid intelligence and
standardized math and verbal tests assessing academic performance. The fluid
intelligence data were decomposed into a learning component that was associated
with the position effect of intelligence items and a constant component that was
independent of the position effect. Results showed that the learning component
contributed significantly more to the prediction of math and verbal performance
than the constant component. The link from the learning component to math
performance was especially strong. These results indicated that fluid
intelligence, which has so far been considered as homogeneous, could be
decomposed in such a way that the resulting components showed different
properties and contributed differently to the prediction of academic
performance. Furthermore, the results were in line with the expectation that
learning was a predictor of performance in school. 相似文献

In category-specific agnosia (CSA) patients typically have more trouble naming animals, fruits, and vegetables than tools, furniture, and articles of clothing. A crucial exception to this living vs nonliving rule involves the category of musical instruments. Patients with problems naming living objects often repeatedly fail to name musical instruments. In CSA it is crucial to equate living and nonliving object lists on object name frequency, complexity, and familiarity. The present study shows, however, that even the most rigorously controlled object lists can lead to erroneous conclusions if nonliving stimuli contain an overrepresentation of musical instruments. Naming capabilities of a herpes encephalitis patient were assessed using matched lists of living and nonliving objects and showed no indication of category-specific deficits. When exemplars were separated into biological objects, musical instruments and man-made artifacts, strong category-specificity emerged: artifact naming was flawless whereas musical instrument and biological object naming were both severely impaired. It is concluded that CSA is a veridical phenomenon but that our understanding of CSA is limited by adhering to the spurious living/nonliving distinction. 相似文献

The production of transitive limb gestures is optimized when the appropriate tool can be physically manipulated. Little research has addressed the independent contributions of visual and nonvisual sources of sensory information to this phenomenon. In this study, 12 control, 37 LHD, and 50 RHD stroke patients performed transitive limb gestures to pantomime (to verbal command with the object visible) and object manipulation. Performance was more accurate in the object manipulation condition, suggesting that haptic and kinesthetic cues are important for transitive gesture production. Various patterns of performance were observed in the stroke groups, indicating that selective damage to the haptic/kinesthetic processing system is possible and common following unilateral stroke. 相似文献

Participants with a lifetime history of posttraumatic stress disorder (PTSD) and trauma-exposed controls with no PTSD history completed an emotional working memory capacity (eWMC) task. The task required them to remember lists of neutral words over short intervals while simultaneously processing sentences describing dysfunctional trauma-related thoughts (relative to neutral control sentences). The task was designed to operationalise an everyday cognitive challenge for those with mental health problems such as PTSD; namely, the ability to carry out simple, routine tasks with emotionally benign material, while at the same time tackling emotional laden intrusive thoughts and feelings. eWMC performance, indexed as the ability to remember the word lists in the context of trauma sentences, relative to neutral sentences, was poorer overall in the PTSD group compared with controls, suggestive of a particular difficulty employing working memory in emotion-related contexts in those with a history of PTSD. The possible implications for developing affective working memory training as an adjunctive treatment for PTSD are explored. 相似文献

Conclusion The systems T
N and T
M show that necessity can be consistently construed as a predicate of syntactical objects, if the expressive/deductive power of the system is deliberately engineered to reflect the power of the original object language operator. The system T
N relies on salient limitations on the expressive power of the language L
N through the construction of a quotational hierarchy, while the system T
Mrelies on limiting the scope of the modal axioms schemas to the sublanguage L
infM
+, which corresponds exactly with the restrictive hierarchy of L
N. The fact that L
infM
+ is identical to the image of the metalinguistic mapping C
+ from the normal operator system into L
M reveals that iterated operator modality is implicitly hierarchical, and that inconsistency is produced by applying the principles of the modal logic to formulas which have no natural analogues in the operator development. Thus the contradiction discovered by Montague can be diagnosed as the result of instantiating the axiom schemas with modally ungrounded formulas, and thereby adding radically new modal axioms to the predicate system.The predicate treatment of necessity differs significantly from that of the operator in that the cumulative models for the predicate system are strictly first-order. Possible worlds are not used as model-theoretic primitives, but rather alternate models are appealed to in order to specify the extension of N, which is semantically construed as a first-order predicate. In this manner, the intensional aspects of modality are built into the mode of specifying the particular set of objects which the denotation function assigns to N, rather than in the specification of the basic truth conditions for modal formulas. Intensional phenomena are thereby localised to the special requirements for determining the extension of a particular predicate, and this does not constitute a structural modification of the first-order models, but rather limits the relevant class of models to those which possess an appropriate denotation function. 相似文献
