360°-multiple object tracking in team sport athletes: Reliability and relationship to visuospatial cognitive functions

IntroductionIn team sports, the ability to visually track the movements of teammates and opponents simultaneously is a critical aspect of success. In sports psychology, this ability can be examined with the help of the multiple object tracking paradigm. The current study investigated the relationship between task performance in a novel 360°-multiple object tracking task and visuospatial cognitive functions as well as the reliability of the task.MethodsIn a sample of 153 team sport athletes the relationships between performance in the 360°-multiple object tracking task and performance in a spatial attention task, a spatial working memory task, and a fluid intelligence task at a first time of measurement were investigated. Additionally, at a second time of measurement the test-retest reliability of the 360°-multiple object tracking task was measured over a six-week interval in a subsample of 65 athletes.ResultsThe expected significant correlations between the performance in the 360°-multiple object tracking task and the tasks measuring spatial attention and working memory were observed. Test-retest reliability analysis indicated a good reliability of the procedure.ConclusionsThe results of this study demonstrate that the novel 360°-multiple object tracking task allows the reliable assessment of visuospatial cognitive performance of athletes in a dynamic 360°-environment.     

Sports Media Representations of Concussions in the National Rugby League

Objective

Concussion is poorly understood by the general public who are regularly exposed to this type of injury via televised sports such as the National Rugby League (NRL). This study investigated media representations of concussion by examining the terminology used by the commentators during the 2010 and 2011 NRL seasons.

Method

Data was obtained through a surveillance design where commentary statements were recorded for each observable concussion.

Results

Dramatic terminology was the most frequently used followed by entertaining and humorous terminology. Commentators often portrayed the way the incident had occurred and the player's reaction to being concussed. However, information about a player sustaining an injury that required medical attention was rarely conveyed.

Conclusion

Media tend to trivialise concussion and this may have an impact on the public's knowledge of, and influence their response to, concussion.     

Development of the Sports Performance Inventory: A Psychological Measure of Athletic Potential

The current study extends existing sport psychology research by developing a more comprehensive athlete attitudinal survey—the Sports Performance Inventory (SPI). A multiple item survey consisting of sport-related attitudinal items was distributed to 274 students enrolled in a large Division I Midwestern university. A principal components analysis with varimax rotation performed on the original survey items resulted in an 83 item survey with six interpretable factors: Competitiveness, Team Orientation, Mental Toughness, Emotional Control, Positive Attitude, and Safety Consciousness. All subscales demonstrated adequate item discriminability and internal consistency. Important statistically significant differences between college/novice and male/female athletes were found: (1) College athletes were found to have a higher SPI composite than novice athletes; (2) College athletes were found to have a more positive attitude than novice athletes; (3) College athletes were more competitive than novice athletes; (4) Females were more team oriented than males; and (5) Novice males were more competitive than novice females, while college females were more competitive than college males. Implications of these findings and suggestions for future research are discussed.     

Cohesiveness, coach's interpersonal style and psychological needs: Their effects on self-determination and athletes' subjective well-being

GoalThe goal of this study was to test the impact of cohesiveness and coaches' controlling interpersonal style on athletes' perceptions of autonomy, competence and relatedness. A contextual motivation sequence [Vallerand, R. J. (1997). Toward a hierarchical model of intrinsic and extrinsic motivation. In M. Zanna (Ed.), Advances in experimental social psychology, Vol. 29 (pp. 271–360). New York: Academic Press.] was tested whereby social factors supporting the satisfaction of basic needs would increase the level of sport self-determination, which in turn, should predict subjective well-being in athletes.MethodThe proposed sequence was tested with 197 basketball players using structural equation modeling. The hypothesized model was supported.ResultsPerceptions of cohesiveness positively predicted the satisfaction of the basic needs. Perceptions of coaches' controlling interpersonal style negatively impacted feelings of autonomy. In turn, psychological needs predicted self-determination in sports ensuing greater sport satisfaction and positive emotions in sports. Tests of indirect effects also supported the mediating role of psychological needs and self-determination.ConclusionResults are discussed in light of the different types of motivational antecedents and their influence on the psychological needs.

Media and violence: The case of professional football championship games

Recently much research has linked media violence with actual violence. The most serious violence, suicides, and homicides have been connected to events portrayed in the mass media. In this study I examine the effect of NFL football playoff games on the relative incidence of homicides between standard metropolitan statistical areas (SMSAs) with and without participating teams. Results show that homicides may be related to participation. Specifically, SMSAs with losing teams experience significantly more homicides than SMSAs with winning teams.     

Does game pressure affect hand selection of NBA basketball players?

PurposeThe purpose of this study was to compare hand selection and accuracy of technical skills between low- and high-pressure games of the National Basketball Association (NBA) in the 2018–2019 regular season and playoffs.MethodA notational analysis was conducted on 24 games of four teams (12 low-pressure games and 12 high-pressure games, six of each team, three in each condition). One- or two-handed actions were recorded for dribbling, passing, catching, and shooting (layups, dunks, hooks, and tips) skills.ResultsDuring high-pressure games, players significantly increased the frequency of right-handed passing. High-pressure games also increased the frequency of left-handed catching. For dribbling and shooting, no differences were observed in hand frequency between conditions. The success rate of all analyzed skills was similar between the hands in both low- and high-pressure conditions.ConclusionOur results showed that game pressure could selectively modulate hand preference for passing and catching skills in elite-level basketball while presenting no significant effect on performance between hands.     

Elite golfers are characterized by psychomotor refinement in cognitive-motor processes

The present study extends the sport neuroscience literature by comparing elite and amateur golfers during golf putting and examining the essential cognitive-motor processes that may contribute to understanding the superior cognitive-motor performance of skilled performers. Twenty elite and 18 amateur golfers were recruited to perform 60 putts while individual EEGs were recorded. Compared with the amateur golfers, the elite golfers were characterized by (1) lower alpha 2 power at Pz and T8 2 s before putt release; (2) lower alpha 2 power at Fz and T8 and lower mu 2 power 1 s before putting; and (3) lower alpha 2 coherence at Fz–T7 and Fz–T8. This suggests that the elite golfers had higher levels of attention to response motor programming and visuospatial attention and less cognitive-motor interference before putting. These findings not only point to the importance of refining brain processes but also specify essential cognitive-motor processes for superior performance in athletes.     

Reexamining the Calculus of Voting

This study applies social cognitive theory to the study of voter turnout, examining the effects of self‐efficacy on citizens' decisions of whether or not to vote. Consistent with recent arguments in cognitive psychology ( Fenton‐O'Creevy, Nicholson, Soane, & Willman, 2003, 2005 ), I argue that excessive perceptions of self‐efficacy lead some citizens to overestimate their vote's impact in close elections and to vote as a consequence of these perceptions. This illusion of control is further engendered by the features of skill‐based activities such as choice, personal involvement, stimulus familiarity, and exertion of effort ( Langer, 1975 ) that are inherent in the act of voting. Employing both cross‐sectional and panel data, I find that individuals with high levels of self‐efficacy are more likely to be moved to vote by perceptions that an election will be close than are citizens with low levels of self‐efficacy.     

“The ball don't lie”: How inequity aversion can undermine performance

Previous research has found that people are often averse to inequity, even when it works to their own advantage. The present research extends previous demonstrations of inequity aversion by examining how it plays out in a real-world context in which self-interest motivations and competitive pressures are substantial. National Basketball Association games were examined and instances of obviously incorrect foul calls were identified. Players were found to make a substantially lower percentage of the foul shots they were awarded as a result of incorrect calls, indicating that they were troubled by the inequity. This drop-off in performance was only observed when the shooter's team was ahead, highlighting the trade-off between the two conflicting motives of self-interest (the desire to win) and inequity aversion.
