Traditional methods for quantifying sport performances are limited in their capacity to describe the complex interactions of events that occur within a performance over time. The following article outlines a new approach to the study of actions between players in team sports—mainly, soccer. Since the observational design is nomothetic, point, and multidimensional, an observational and data-collecting instrument has been developed. The instrument is mixed and combines a field format with a category system for game events, as well as an ad hoc instrument that considers the game actions of one or both teams, each recorded according to the same criteria. The article also outlines a new approach to the analysis of time-based event records—in this case, sports performance—known as T-pattern detection. The relevant elements of the T-pattern detection process are explained, and exemplar data from analyses of soccer matches are presented to highlight the potential of this form of data analysis. The results suggest that it is possible to identify new kinds of profiles for both individuals and teams on the basis of observational criteria and a further analysis of temporal behavioral patterns detected within the performances.  相似文献

Speech is produced mainly in continuous streams containing several words. Listeners can use the transitional probability (TP) between adjacent and non-adjacent syllables to segment "words" from a continuous stream of artificial speech, much as they use TPs to organize a variety of perceptual continua. It is thus possible that a general-purpose statistical device exploits any speech unit to achieve segmentation of speech streams. Alternatively, language may limit what representations are open to statistical investigation according to their specific linguistic role. In this article, we focus on vowels and consonants in continuous speech. We hypothesized that vowels and consonants in words carry different kinds of information, the latter being more tied to word identification and the former to grammar. We thus predicted that in a word identification task involving continuous speech, learners would track TPs among consonants, but not among vowels. Our results show a preferential role for consonants in word identification.  相似文献

The aim of this study was to develop a Self-Talk Inventory for young adults. This inventory consisted of two scales. The Negative Self-Talk Scale included three categories of self-talk (depressive, anxious, and angry thoughts) and the Positive Self-Talk Scale, three categories (minimization, positive orientation, and coping self-instructions). Participants were 982 undergraduate students (Mean age = 20.35 years, SD = 2.16). They completed the self-talk scales together with the following scales to measure symptoms of affective disorders: the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), and the State-Trait Anger Expression Inventory (STAXI-T). Factor analyses confirmed the hypothesized structure for the Self-Talk Inventory. The relations between self-talk and symptoms of affective disorders (depression, anxiety, and anger) were also evaluated. In general, states-of-mind -SOM- ratios and negative cognitions showed a greater association with psychological symptoms than did positive cognitions. Results concerning the cognitive characteristics of depression, anxiety, and anger were mixed and partially supported the cognitive content specificity theory.  相似文献

McArthur LH  Holbert D  Peña M 《Adolescence》2005,40(160):801-816
Using survey methodology, this exploratory study examined the attitudinal and perceptual dimensions of body image among 1,272 eighth- and ninth-grade males and females from higher and lower socioeconomic backgrounds in Buenos Aires, Argentina (n = 195), Guatemala City, Guatemala (n = 212), Havana, Cuba (n = 213), Lima, Peru (n = 218), Panama City, Panama (n = 195), and Santiago, Chile (n = 239). The two dimensions of body image were assessed by showing the participants nine male and nine female silhouettes depicting body sizes ranging from extremely thin (#1) to extremely obese (#9). Approximately 50% of the male and female adolescents chose silhouette #3 as best depicting the attractive male body. Silhouette #2 was chosen by 45% of the females as best depicting feminine attractiveness, while 45% of the males chose silhouette #3. When identifying the silhouette that best depicted the healthy male body, 26% of the participants chose silhouette #2, 41% chose #3, and 19% chose #4. Silhouette #2 was selected by 33% of the adolescents as best depicting the healthy female body, 38% chose #3, and 14% chose #4. In all cities, the effect of body mass index (BMI) on body satisfaction was highly significant (p < 0.001). Almost 40% of the middle weight adolescents indicated a preference to be thinner, even though 72% of the males and 84% of the females in this subgroup already perceived themselves as thin. Similarly, 89% of the heavier weight participants indicated a preference to be thinner, even though only 10% of the males and 2% of the females in this subgroup perceived themselves as heavy. In five of the six cities, a significantly higher (p < 0.05) percentage of females than males desired to be thinner, the exception being Havana, where the distribution of desired change in body size was almost identical for males and females. Findings suggest a need for culturally sensitive, age- and gender-specific preventive interventions focusing on the importance of achieving a healthy weight during adolescence to promote body size acceptance among adolescents who are at a healthy weight.  相似文献

Explicit and implicit memory biases in depression and panic disorder   总被引:2,自引:0,他引:2  
The purpose of the present study was to investigate the presence of a bias for emotional information (panic-related, depression-related, positive and neutral) in explicit memory and implicit memory (by means of free recall and word-stem completion tasks, respectively) among depressed (N=20) and panic (N=20) patients. Three different encoding conditions (graphemic, semantic and self-reference) were used. The results of this study failed to show the existence of a mood-congruent memory bias for both implicit and explicit memory in these emotional disorders. According to the correlational analyses performed, differences among categories of emotional words meant less than the difference among various types of encoding and memory bias in order to differentiate among groups.  相似文献

Relations between mothers’ tendency to comment appropriately on their 8-month-olds’ internal states (mind-mindedness) and children’s behavioral difficulties (Strengths and Difficulties Questionnaire) at ages 44 and 61 months were investigated in a socially diverse sample (N?=?171, 88 boys). Controlling for maternal depressive symptoms, perceived social support, sensitivity, child language ability, and child gender, maternal mind-mindedness was negatively related to children’s externalizing and internalizing behaviors specifically in low socioeconomic status (SES) families. Furthermore, behavioral difficulties at age 44 months mediated the relation between maternal mind-mindedness and behavioral difficulties at age 61 months, but only for low SES families. These findings are discussed with reference to possible ways in which mind-mindedness could inform interventions targeted at at-risk groups.  相似文献

Resumen

En este artículo se realiza una aproximación al estudio y evaluación del lenguaje desde una perspectiva psicosocial. El objetivo prioritario de esta investigación es conocer y exporter la importancia y relevancia que poseen ciertas variables socioeconómicas culturales, tipificadas como indicadores sociales, sobre el rendimiento en lenguaje, evaluado a través del I.T.P.A., de una muestra de escolares del Ciclo Medio de la E.G.B, en Galicia.  相似文献

In recent years, public science events have been designed as a means to foster a dialogue between science and the public and to contribute to ongoing policy processes. Regardless of their tangible outcome, such events rely on a certain framing, reconfigure scientific knowledge and conceptualise the public in specific ways. These constructs are exemplified by a science festival that was held in the train station hall in Zurich. Novel insights can be gained from a spatial, an object and an actor-related approach borrowed from the artistic context: the discussions about the White Cube can be adapted to contribute to the analysis of the science festival. When we look into the spatial situation created to foster exchange about scientific knowledge, we find how the exhibition display is taking care of minor details. While the organisers transformed the station hall into a laboratory, they created a kind of dialogic situation that filled an authority gap as it equally enabled exchange. The objects put in place in the exemplary case helped to design a customer–supplier relationship between the public and science. Under the umbrella of the science event, a range of diverse research endeavours was homogenised and unified. The audience, finally, was invited to familiarise itself with scientific knowledge. However, they were allocated a consumer role that obliged them to remain guests in the laboratory environment of the station hall. Thus, public science events may be successful in attracting large attendance and allowing more experiences with science, but while they create novel forms of familiarisation with science for visitors, they do not necessarily remedy public doubts about science and technology.  相似文献

RESUMEN

En esta entrevista Bem comenta la relación entre sus aportaciones científicas -el estudio psicológico de los roles sexuales a nivel tanto instrumental como conceptual- y su compromiso personal a favor de unas relaciones más igualitarias entre las personas, ofreciendo una visión comprehensiva de su evolución profesional y personal y repasando las cuestiones más interesantes de la etapa de estudios sobre androginia (1974–1979) y de su actual enfoque cognitivo. Tras comenzar explicando su formación y trayectoria científica, así como las motivaciones que han guiado su trabajo, la autora realiza un análisis crítico del Bem Sex Role Inventory (BSRI). Seguidamente profundiza en diversos aspectos del concepto “androginia” acuñado por ella y explica las razones por las que a partir de 1979 los sujetos tipificados sexualmente se convierten en el blanco de su teoría sobre el esquema cognitivo del género, así como la caracterización de los conceptos masculinidad y/o feminidad como constructos cognitivos. La entrevista finaliza con algunas alusiones acerca de cómo educar a los niños de una “forma no esquemática” con respecto al género y señalando sus preocupaciones científicas más recientes en torno al concepto de género en los niños.  相似文献
