We investigated the readability of seven mental health brochures on mental, emotional, and behavioral disorders in children that were selected from a website developed by the Center for Mental Health Services at http://www.mentalhealth.org. The reading grade levels of the brochures ranged from 11.1 to 14.8 (mean 13.23), considerably higher than the 8th grade level recommended for educational material by the U. S. Department of Education (1986). On other readability variables, assessed using the Readability Assessment Instrument (RAIN; Singh, 1994), all brochures met criterion on most variables but failed on those for new words (audience appropriateness) and print size. This is a favorable result in comparison with other studies that have assessed readability of mental health information on the Internet using the RAIN, although less so with reading grade levels.  相似文献

Executive functions (EF) are crucial for the athletes’ success, and they are even more essential in open skill sports (e.g. volleyball and football). In these sports, due to continuously changing conditions, goal-directed behaviours need to be repeatedly adjusted and corrected. One of the most important EF is the ability to continuously switch between two different tasks being required in a random sequence. We used a task-switching protocol in elite volleyball athletes, usually playing different roles, with the aim of evaluating if each role is characterized by specific switching abilities. On the basis of the specific competences requested by the game, thirty-six elite volleyball athletes were assigned to three groups: Strikers, Defenders and Mixed. Each player completed a customized sport-specific task-switching paradigm. Data evidenced that each role has specific characteristics. In Reaction Times, the Strikers were the fastest to answer to stimuli, while the Defender group provided a worse performance, particularly when defensive actions, that probably require more cognitive elaboration, had to be processed. Different effects emerged by the Errors. In fact, the Mixed group, which was the one with more expertise, appeared to be more accurate in the responses.Although preliminary, these results showed a minimal degree of cognitive flexibility for highly specialized Strikers and a maximum level for Mixed, allowing thus to highlight specific profiles of athletes. Data observed indicate the possibility to develop a test assessing the executive domain during the recruitment in a team, revealing a useful tool for choosing the most suitable role.  相似文献

Preschoolers are well known for their poor working memory (WM) performance. This could result from goal neglect, which would hamper the setting of maintenance strategies. Previous studies have shown that preschoolers’ WM performance can be improved in game-like tasks, because they provide cues to support goal maintenance. However, in these studies, it was unclear what features of the task (either the main toy or the motor activity required by the game) provide efficient cues. The aim of the present study was to disentangle the two features to examine cue effects in 5- to 7-year-old children. No improvement of WM performance was observed when the toy was a potential goal cue, whereas the motor activity had a detrimental effect in all age groups. The latter effect could result from a distraction of attention from attention-based maintenance activities. Hence, preschoolers' poor WM performance would not be fundamentally due to goal neglect.  相似文献

Based on the risk homeostasis theory, the aim of this study was to assess acceptable risk, measured by personality factors, and risk perception, measured by physiological arousal, as predictors of risky behavior in young adult pedestrians, as well as to assess for gender differences. Eighty-two young adults, aged 18–30, completed self-report measures about risky pedestrian behaviors and these personality traits: impulsiveness, conscientiousness and openness to experience. Sixty-four of these participants then took part in an experimental task designed to assess their perception of the level of risk in situations involving different interactions between cars and pedestrians. Risk perception was assessed by these physiological responses: heart rate, skin conductance level, and skin conductance response. Results showed that risky behavior had significant correlations with impulsiveness, conscientiousness, and skin conductance level. Gender differences also emerged in risky behavior, impulsiveness, conscientiousness, and skin conductance level. Finally, a structural equation model showed that impulsiveness, conscientiousness and the difference in skin conductance level between risky and neutral situations predicted risky pedestrian behaviors, and explained 23.6% of the its variance, after controlling the effect of gender. Implications for evaluation, prevention, and intervention for risky pedestrian behaviors are discussed.  相似文献

In his enormously influential The Modularity of Mind, Jerry Fodor (1983) proposed that the mind was divided into input modules and central processes. Much subsequent research focused on the modules and whether processes like speech perception or spatial vision are truly modular. Much less attention has been given to Fodor's writing on the central processes, what would today be called higher‐level cognition. In “Fodor's First Law of the Nonexistence of Cognitive Science,” he argued that central processes are “bad candidates for scientific study” and would resist attempts at empirical analysis. This essay evaluates his argument for this remarkable claim, concluding that although central processes may well be “messier” than input modules, this does not mean that they cannot be studied and understood. The article briefly reviews the scientific progress made in understanding central processes in the 35 years since the book was published, showing that Fodor's prediction is clearly falsified by massive advances in topics like decision making and analogy. The essay concludes that Fodor's Law was not based on a clear argument for why the complexities of central systems could not be studied but was likely based on intuitions and preferences that were common in psychology at the time.  相似文献

Hagger (2019) offers an insightful synthesis of recent theoretical and empirical developments in understanding of habit and its relevance to physical activity. This commentary extends coverage of one such advance, namely the distinction between two manifestations of habit in physical activity: habitually ‘deciding’ to engage in activity (i.e. habitual instigation), and habitually ‘doing’ the activity (habitual execution). We explore the rationale for this distinction and argue that most contemporary theory and evidence around habitual physical activity – and by extension, Hagger’s review – implicitly focuses on instigation and neglects execution. We offer hypotheses around the potential roles that habitual execution may play in physical activity. Broadening the scope of inquiry within the field to more fully encompass habitual performance would achieve a more comprehensive and informative account that incorporates concepts of skill acquisition and mastery.  相似文献

In Religion in an Age of Science , Ian Barbour concludes that the contemporary evolutionary worldview with its emphasis on the interplay of law and chance, relationality and autonomy, can be properly accounted for only by something like the process-relational metaphysics of Alfred North Whitehead. At the same time, he expresses serious reservations about certain features of Whitehead's scheme, notably, his perceived inability to account for the ongoing identity of the human self and for the fact of multilevel organization within organisms and in the world of inanimate compounds. In this article, I suggest that both of these difficulties can be resolved if one adopts a revisionist understanding of the Whiteheadian category of society according to which democratically organized societies possess an ontological unity and exercise a corporate agency proper to their own level of existence and activity. Furthermore, if one applies this revisionist understanding of societies to the Whiteheadian doctrine of God, a Trinitarian understanding of God becomes possible within the overall parameters of process-relational metaphysics. In this way, traditional belief in the doctrine of the Trinity can be reconciled with a scientifically credible worldview.  相似文献

Individual differences in spatial memory among young and aged rats were assessed using memory tasks related to integrity of the hippocampus and the neostriatum. Relationships were then examined between measures of spatial memory and regional choline acetyltransferase (ChAT) activity, a marker for cholinergic integrity. Twenty-four-month-old Long-Evans rats were impaired in comparisons with 6-month-old rats on measures of place learning, working memory, reference memory, and perseveration in water-maze tasks. Aged rats that were impaired on one measure of memory, however, were not necessarily impaired on other measures. ChAT activity in the ventromedial and dorsolateral neostriatum of aged rats was significantly reduced in comparisons with young rats whereas no difference was found in the hippocampus. Aged rats with the most ChAT activity in the anterior ventromedial neostriatum performed best on the place-learning and reference memory tasks but also made the most perseverative errors on the working memory task. In addition, young and aged rats with the most ChAT activity in the anterior dorsolateral neostriatum were those with the least accurate working memory. No relationships were found between ChAT activity in the hippocampus and spatial memory. Thus age-related memory impairment has components that can be segregated by measuring relationships between cholinergic integrity in subregions of the anterior neostriatum and memory tasks with different strategic requirements.  相似文献

This research examines how social trust translates into dynamics of mobilisation for inclusion or exclusion in Swiss cantons by studying how social trust is linked to equality‐directed protest intention versus radical right support, comparing individual‐level and contextual‐level relationships. The study is based on data from the Swiss Household Panel collected between 2002 and 2008. The impact of individual‐level and contextual‐level social trust is analysed in three‐level regression models of repeated observations, nested in individuals who are nested in cantons. The results indicate complex patterns that depend on the level at which social trust is assessed and confirm the need for a contextualised view of social trust and social capital. For individuals, higher social trust is associated with higher protest intention and lower radical right support. However, in cantons characterised by higher rates of social trust, individuals are less likely to engage in protest actions and more likely to support the radical right. Further analyses show that canton‐level social trust is intertwined with other contextual factors, suggesting that in certain configurations, that is, combined with low levels of cultural and social diversity, climates of social trust may be linked to more restricted forms of solidarity and the persistence of inequality.
