Differences in the neurocognitive profiles of professional and semi-professional male South African rugby union players

This study investigated possible cognitive functioning profile differences between professional and semi-professional rugby players. Seventy-nine male rugby union players (professional = 55, semi-professional = 24; age range = 19–37 years) participated in the study. The players completed a battery of neuropsychological functioning tests covering the following domains: memory tasks, attention and behavioural tasks, sensory-motor tasks, executive functioning tasks, verbal tasks, and emotion identification tasks. Results following Fisher’s exact test comparisons revealed no significant group differences in the cognitive functioning profiles.     

Modulation of brain oscillations during fundamental visuo-spatial processing: A comparison between female collegiate badminton players and sedentary controls

ObjectivesThe present study aimed to investigate the difference in fundamental cognitive processing and neural oscillations between badminton players and sedentary controls.DesignA cross-sectional design was adopted to address this issue.MethodsWe compared time-frequency electroencephalographic (EEG) activity from collegiate female badminton players (n = 12, aged 20.58 ± 2.75 years) and age-and gender-matched sedentary non-athletic controls (n = 13, aged 19.08 ± 2.10 years) when they performed a task that involves visuo-spatial attention and working memory.ResultsWe observed that players responded faster than controls on the task without suffering any increase in error responses. Correspondingly, the players, relative to controls, exhibited higher task-related modulations in beta power in the attention condition as well as in theta and beta power in the working memory condition. Notably, the behavior-EEG correlations revealed that better attention performance is associated with lower beta power, while greater working memory is related to higher theta power.ConclusionsOur results shed light on the mechanisms of athletic superiority in fundamental cognitive functioning: the higher theta synchronization points to a greater engagement of attention, whereas the higher beta desynchronization supports the contribution of processing speed (or motor-related processing) to better performance in athletes. This study extends current understanding by suggesting that enhanced neurocognitive function seen in athletes may transfer to fundamental tasks, giving insight into the generalizability of sport experience to neurocognitive functioning.     

Mental rotation performance in soccer players and gymnasts in an object-based mental rotation task

In this study, the effect of motor expertise on an object-based mental rotation task was investigated. 60 males and 60 females (40 soccer players, 40 gymnasts, and 40 non-athletes, equivalent males and females in each group) solved a psychometric mental rotation task with both cube and human figures. The results revealed that all participants had a higher mental rotation accuracy for human figures compared to cubed figures, that the gender difference was reduced with human figures, and that gymnasts demonstrated a better mental rotation performance than non-athletes. The results are discussed against the background of the existing literature on motor experts, mental rotation performance as well as the importance of the testing situation and the test construction.     

中国人社会认知研究的沿革、趋势与理论建构

社会认知是指个体对社会性客体和社会现象及其关系的感知与理解。根据对象可以分为自我认知、人际认知、群际认知以及以社会决策为核心的社会事件认知。针对以上四个方面, 国内学者开展了一系列有益的探索, 为中国人社会认知的研究做出了先驱性贡献。但无论就理论建构、研究范式还是研究内容而言, 大量研究沿袭了国外研究的预设前提与范畴, 即“本位认知”, 脱离了中国人社会认知滋长的基础--以“差序格局”为基调的传统文化以及当前剧烈的社会变迁背景下转型期的文化。通过梳理与整合涉及社会认知主题的研究及其内在逻辑, 发现中国人社会认知的根本特点为“他位认知”, 并且集中体现为“差序格局”文化衍生与发展的“群际认知(阶层认知)”, 进而尝试围绕“群际认知”这条主线解读与建构中国人社会认知的理论框架, 推进中国人社会认知的深层研究, 具有深刻的理论与现实意义。     

You can't tell the players without a scorecard: A typology of horse players

Horse racing, America's number one spectator sport, attracts a loyal core of patrons who persist at gambling on horses despite the low probability of financial gain. Traditional perspectives which view gambling as a social problem and the behavior of its regular participants as deviant have narrowly restricted scientific investigation into a track milieu, and the wide range of behaviors demonstrated by these gamblers have never been placed into a systematic framework. Using data collected from an empirical investigation of several race track settings, I identify a community‐designated typology of “horse players.” This typology is unique and serves as an initial conceptual model for objective inquiry into behavior of inveterate horse race gamblers.     

Using robots to understand animal cognition

In recent years, robotic animals and humans have been used to answer a variety of questions related to behavior. In the case of animal behavior, these efforts have largely been in the field of behavioral ecology. They have proved to be a useful tool for this enterprise as they allow the presentation of naturalistic social stimuli whilst providing the experimenter with full control of the stimulus. In interactive experiments, the behavior of robots can be controlled in a manner that is impossible with real animals, making them ideal instruments for the study of social stimuli in animals. This paper provides an overview of the current state of the field and considers the impact that the use of robots could have on fundamental questions related to comparative psychology: namely, perception, spatial cognition, social cognition, and early cognitive development. We make the case that the use of robots to investigate these key areas could have an important impact on the field of animal cognition.     

How we think and act together

In this paper, I examine the challenges socially extended minds pose for mainstream, individualistic accounts of social cognition. I argue that individualistic accounts of social cognition neglect phenomena important to social cognition that are properly emphasized by socially extended mind accounts. Although I do not think the evidence or arguments warrant replacing individualistic explanations of social cognition with socially extended explanations, I argue that we have good reason to supplement our individualistic accounts so as to include the ways in which situational context affects social interactions. The result, I hope, is a more sophisticated individualism that offers a more comprehensive account of how we think and act together.     

Predicting consumer satisfaction from CD players

This paper explores the relationship between expectations and product satisfaction evaluations in a high‐involvement product category. While doing so, the paper attempts to develop a regression model to predict the overall level of consumer satisfaction derived from CD players, using a number of explanatory variables within an ordinary least squares framework. This regression model links overall satisfaction to confidence in other people's opinions, expectations of product quality, experience with product quality, replacement rate and the importance of price. The model predicts fairly well for cross‐sectional data, with an adjusted R² of 57 per cent, and appears to be robust. Finally, the implications of these results for marketers are discussed.

The commitment of young soccer players

The main purpose of this study was to test the Sport Commitment Model in young soccer players. Participants' ( N = 437) age ranged from 14 to 16 years. Based on the sport commitment model proposed by Scanlan and colleagues, 6 scales and 28-items constitute the Sport Commitment Questionnaire (SCQ). Results of this study provide some support for the reliability and validity of the SCQ, using a sample of young soccer players. Reliability analysis provided acceptable internal consistency for four scales: Sport Commitment, Sport Enjoyment, Involvement Alternatives and Social Constraints. Sport Enjoyment (Beta= .56, p <.001) and Involvement Alternatives (Beta= -.40, p <.001) were the strongest sport commitment predictors. Further studies with a broader age range, different genders, and other sports or competitive levels are required to continue analyzing the sport commitment model.     

Personality profiles of young chess players

Although the game of chess has often featured in psychological research, we know very little about people who play chess, especially about children who take up chess as a hobby. This study presents the personality profiles as measured with the Big Five model (BFQ-C; Barbaranelli, Caprara, Rabasca, & Pastorelli, 2003) of 219 young children who play chess and 50 of their peers who do not. Children who score higher on Intellect/openness and Energy/extraversion are more likely to play chess while children who score higher on Agreeableness are less likely to be attracted to chess. Boys with higher scores on Agreeableness are less likely to take up chess than boys with lower scores. Considering that girls score higher on Agreeableness, this factor may provide one of the possible reasons why more boys are interested in chess. Although none of the Big Five factors were associated with self-reported skill level, a sub-sample of 25 elite players had significantly higher scores on Intellect/openness than their weaker chess playing peers.

Functional research and cognitive‐process research in behavioural science: An unequal but firmly connected pair

Drawing on illustrative examples of the functional and cognitive psychology in contemporary research, the present article emphasizes the primacy of functional relationships, which provide the fundament for all attempts to uncover invisible cognitive processes. Cognitive research is not only inherently more difficult and much more ambitious than functional research. It also suffers from several home‐made problems, such as unwarranted inferences from model fitting, the mediation‐analysis cult and the failure to take environmental influences into account. However, despite the primacy of functional psychology and the problems associated with the ambitious goals of cognitive research, the two partners in this unequal pair are firmly connected and jointly responsible for the most impressive examples of progress in behavioural science.     

Controlling competitive anger among male soccer players

Abstract

This study examined the effectiveness of anger awareness training (i.e., self-monitoring) and role-playing (i.e., modeling and behavioral rehearsal) in reducing participants’ angry behavior and angry feelings. Male participants (N = 57) from intact soccer teams were randomly assigned to a role-playing, an anger awareness, or a control group. Pretreatment anger scores indicated that all three groups exhibited similar anger dispositions before the study began. Following pretreatment assessment, angry behavior and self-reported anger were observed and measured during a 15-game round-robin soccer season. Analyses revealed that although angry feelings remained consistent across the duration of the study, the role-playing group was more effective than both the anger awareness and control groups in controlling angry behavior. Findings indicate that although the use of anger awareness and role-playing interventions can reduce angry behavior, the role-playing intervention was a more effective method.

Excess of mixed-footedness among professional soccer players

This study concerns the distribution of footedness among professional soccer players (n=415) and nonsporting university students (n=430). Chi-squared showed that there were statistically significant differences between the proportion of mixed-footedness in the two groups (p<.0001). It appears that mixed-footedness or the ability to use both feet with an almost equal consistency is an important factor in the potential of individuals to reach high skill in soccer play. The mixed-footedness of these professional soccer players can be understood best in terms of both the nature of the game and genetic predisposition. This result is of direct interest in the context of those activities in which structural and functional biases in the lower extremities are important variables in acquisition and performance of motor skill.     

Mood states of professional female tennis players

To develop a psychological profile of professional female athletes, specifically of elite tennis players, 16 professional female tennis players from five countries were given the Profile of Mood States to measure six mood states: tension, depression, anger, vigor, fatigue, and confusion. When age was controlled in the design, older female athletes exhibited the "iceberg profile," i.e., they scored higher on the vigor mood state and lower on all other mood states than college-age women. Younger athletes scored like college-age women. These results only partially support the 1987 work of Morgan, O'Connor, Sparling, and Pate.     

Proximity and precedence in arithmetic

How does the physical structure of an arithmetic expression affect the computational processes engaged in by reasoners? In handwritten arithmetic expressions containing both multiplications and additions, terms that are multiplied are often placed physically closer together than terms that are added. Three experiments evaluate the role such physical factors play in how reasoners construct solutions to simple compound arithmetic expressions (such as “2?+?3?×?4”). Two kinds of influence are found: First, reasoners incorporate the physical size of the expression into numerical responses, tending to give larger responses to more widely spaced problems. Second, reasoners use spatial information as a cue to hierarchical expression structure: More narrowly spaced subproblems within an expression tend to be solved first and tend to be multiplied. Although spatial relationships besides order are entirely formally irrelevant to expression semantics, reasoners systematically use these relationships to support their success with various formal properties.     

How extending your middle finger affects your perception of others: Learned movements influence concept accessibility

Body movements both express and influence how people feel and think. Conceptualizations of this bidirectional influence assume that movement-concept associations can be innate or learned, although evidence for learned associations remained ambiguous. Providing a conservative test of learned movement-concept associations, two studies investigate the influence of culture-specific body movements, which involve an arbitrary relationship between movements and associated concepts. Paralleling the influence of hostility primes, extending the middle finger influenced the interpretation of ambiguously aggressive behaviors as hostile, but did not influence unrelated trait judgments (Study 1). Paralleling the effects of global evaluative primes, upward extension of the thumb resulted in more positive evaluations of the same target along all trait dimensions and higher liking of the target (Study 2).
