Objectives

This study aimed to establish the prevalence, pattern and nature of coaches’ verbal behaviour at children’s (ages 6-12 years) team sports events. The study draws upon the motivational model presented by Mageau and Vallerand (2003) to examine the influence of global (gender), contextual (sport related), and social (athlete gender) factors on coach comments.

Design

A cross-sectional observational study of coaches stratified across four team sports: Rugby Union, Netball, Association Football and Touch Rugby.

Method

The Observation Instrument at Sports Events was used to categorise covertly recorded verbal comments made by coaches at organised team sports games.

Results

Overall, 10,697 comments were recorded at 72 games at a rate of 3.71 comments/minute; 35.4% were categorised as positive, 21.6% as negative, and 43.0% as neutral. Significant differences in negative comments were identified between sport (p < .001) with rugby coaches recording the highest percentage of negative comments and the lowest percentage of positive comments; by coach gender (p < .001), with male coaches recording higher rates of negative comments; and by athlete gender (p < .001), with coaches of male-only teams recording higher rates of negative comments. When simultaneously included in a Poisson regression model the difference in negative comments between sports remained statistically significant (p < .001) whereas coach gender was no longer significant.

Conclusions

The ratio of negative coach comments for all sports gives cause for concern. These findings suggest that sports of national and cultural significance are a key driver of coaching behaviours in a competitive environment.  相似文献

The self-concept is one of the main organizing constructs in the behavioral sciences because it influences how people interpret their environment, the choices they make, whether and how they initiate action, and the pursuit of specific goals. Because belonging to social groups and feeling interconnected is critical to human survival, the authors propose that people spontaneously change their working self-concept so that they are more similar to salient social categories. Specifically, 4 studies investigated whether activating a variety of social categories (i.e., jocks, hippies, the overweight, Blacks, and Asians) increased associations between the self and the target category. Whereas Studies 1 and 2 focused on associations between stereotypic traits and the self, Studies 3 and 4 examined self-perceptions and self-categorizations, respectively. The results provide consistent evidence that following social category priming, people synchronized the self to the activated category. Furthermore, the findings indicate that factors that influence category activation, such as social goals, and factors that induce a focus on the interconnectedness of the self, such as an interdependent vs. independent self-construal, can impact this process. The implications of changes to the working self-concept for intergroup relations are discussed.  相似文献

We examined the developmental sequence of letter name knowledge acquisition by children from 2 to five years of age. Data from 2 samples representing diverse regions, ethnicity, and socioeconomic backgrounds (ns = 1074 and 500) were analyzed using item response theory (IRT) and differential item functioning techniques. Results from factor analyses indicated that letter name knowledge represented a unidimensional skill; IRT results yielded significant differences between letters in both difficulty and discrimination. Results also indicated an approximate developmental sequence in letter name learning for the simplest and most challenging to learn letters--but with no clear sequence between these extremes. Findings also suggested that children were most likely to first learn their first initial. We discuss implications for assessment and instruction.  相似文献

A familiar strategy of argument to the effect that natural-language predicates are semantically context dependent rests on constructing what I term Travis cases: different contexts for the use of a predicate are imagined in which its semantic (typically, truth-conditional) properties are claimed to differ. I propose an account of the semantic properties of predicates that give rise to Travis cases; I then argue that the account underwrites a genuine alternative to the standard explanations of Travis cases to be found in the literature; I close with a brief sketch of the connections, required by a fuller development of my account, among the semantic notion of a predicate??s content, the metaphysical notion of a property??s instantiation, and the cognitive notion of a language user??s perspective in using a predicate.  相似文献

The current work examined contributions of emotion-resembling facial cues to impression formation. There exist common facial cues that make people look emotional, male or female, and from which we derive personality inferences. We first conducted a Pilot Study to assess these effects. We found that neutral female versus neutral male faces were rated as more submissive, affiliative, na?ve, honest, cooperative, babyish, fearful, happy, and less angry than neutral male faces. In our Primary Study, we then "warped" these same neutral faces over their corresponding anger and fear displays so the resultant facial appearance cues now structurally resembled emotion while retaining a neutral visage (e.g., no wrinkles, furrows, creases, etc.). The gender effects found in the Pilot Study were replicated in the Primary Study, suggesting clear stereotype-driven impressions. Critically, ratings of the neutral-over-fear warps versus neutral-over-anger warps also revealed a profile similar to the gender-based ratings, revealing perceptually driven impressions directly attributable to emotion overgeneralisation.  相似文献

This study assessed the factor structure, internal consistency, and concurrent validity of a revised instrument, the Composite Codependency Scale (CCS), a 19‐item measure designed to assess codependent traits. Exploratory factor analysis of the CCS, using data from 301 adults from the general population and 49 attending members of Codependents Anonymous (CoDA), yielded three factors: self‐sacrifice, interpersonal control, and emotional suppression. The scale and its subscales exhibited good internal consistency. Consistent with the tenets of the codependency model, higher codependency scores were significantly associated with higher levels of depression, anxiety, stress, and familial dysfunction and lower levels of narcissistic tendencies, self‐esteem, and emotional expressivity. Furthermore, the revised measure effectively discriminated members of CoDA from those in the general population.  相似文献

Two experiments examined whether learning a virtual environment was influenced by field of view and how it related to prior video gaming experience. In the first experiment, participants (42 men, 39 women; M age = 19.5 yr., SD = 1.8) performed worse on a spatial orientation task displayed with a narrow field of view in comparison to medium and wide field-of-view displays. Counter to initial hypotheses, wide field-of-view displays did not improve performance over medium displays, and this was replicated in a second experiment (30 men, 30 women; M age = 20.4 yr., SD = 1.9) presenting a more complex learning environment. Self-reported video gaming experience correlated with several spatial tasks: virtual environment pointing and tests of Judgment of Line Angle and Position, mental rotation, and Useful Field of View (with correlations between .31 and .45). When prior video gaming experience was included as a covariate, sex differences in spatial tasks disappeared.  相似文献

Structural equation models are increasingly used as a modeling tool for multivariate time series data in the social and behavioral sciences. Standard error estimators of SEM models, originally developed for independent data, require modifications to accommodate the fact that time series data are inherently dependent. In this article, we extend a sandwich-type standard error estimator of independent data to multivariate time series data. One required element of this estimator is the asymptotic covariance matrix of concurrent and lagged correlations among manifest variables, whose closed-form expression has not been presented in the literature. The performance of the adapted sandwich-type standard error estimator is evaluated using a simulation study and further illustrated using an empirical example.  相似文献

Against its prominent compatiblist and libertarian opponents, I defend Galen Strawson’s Basic Argument for the impossibility of moral responsibility. Against John Martin Fischer, I argue that the Basic Argument does not rely on the premise that an agent can be responsible for an action only if he is responsible for every factor contributing to that action. Against Alfred Mele and Randolph Clarke, I argue that it is absurd to believe that an agent can be responsible for an action when no factor contributing to that action is up to that agent. Against Derk Pereboom and Clarke, I argue that the versions of agent-causal libertarianism they claim can immunize the agent to the Basic Argument actually fail to do so. Against Robert Kane, I argue that the Basic Argument does not rely on the premise that simply the presence of indeterministic factors in the process of bringing an action about is itself what rules out the agent’s chance for being responsible for that action.  相似文献
