Mental Rotation of Tactical Instruction Displays Affects Information Processing Demand and Execution Accuracy in Basketball

Purpose: In sports games, coaches often use tactic boards to present tactical instructions during time-outs (e.g., 20 s to 60 s in basketball). Instructions should be presented in a way that enables fast and errorless information processing for the players. The aim of this study was to test the effect of different orientations of visual tactical displays on observation time and execution performance. High affordances in visual-spatial transformation (e.g., mental rotation processes) might impede information processing and might decrease execution performance with regard to the instructed playing patterns. Method: In a within-subjects design with 1 factor, 10 novice students were instructed with visual tactical instructions of basketball playing patterns with different orientations either showing the playing pattern with low spatial disparity to the players’ on-court perspective (basket on top) or upside down (basket on bottom). Results: The self-chosen time for watching the pattern before execution was significantly shorter and spatial accuracy in pattern execution was significantly higher when the instructional perspective and the real perspective on the basketball court had a congruent orientation. Conclusion: The effects might be explained by interfering mental rotation processes that are necessary to transform the instructional perspective into the players’ actual perspective while standing on the court or imagining themselves standing on the court. According to these results, coaches should align their tactic boards to their players’ on-court viewing perspective.     

Books: Seekers and persuaders in a brave new world

Rhetoricians have historically been compelled to consider the pragmatic role of intentional obsurity in human communication. This essay examines the highly cohesive directions for obscurantist style in the works of three Hellenistic critics: Demetrius Dionysius of Halicarnassus, and Longinus. Aristides’ encomium To Rome is analyzed briefly to illustrate rhetorical practice which parallels the ancient obscurantist theories.     

Audience support and choking under pressure: A home disadvantage?

This paper highlights the not-so-obvious but compelling reasons why the same supportive audiences that can help performers attain their highest potential also may increase performers' risk of choking under pressure. Drawing primarily from social psychology research and theory, we conclude that audience support magnifies performance pressure and induces performers to avoid failure rather than seek success during the most critical moments of performance contests. Although supportive audiences can inspire performers to excel when motivation would otherwise be lacking, audiences may also lead performers towards maladaptive self-monitoring and overcautiousness when the stakes are highest. The increased self-focus that supportive audiences induce can disrupt the automatic execution of the skills performers possess. Dispositional and situational moderators of the relationship between audience support and performance are reviewed.     

One task,divergent solutions: high- versus low-status sources and social comparison guide adaptation in a computer-supported socio-cognitive conflict task

This experimental study extends conflict elaboration theory (1) by revealing social influence dynamics for a knowledge-rich computer-supported socio-cognitive conflict task not investigated in the context of this theory before and (2) by showing the impact of individual differences in social comparison orientation. Students in two conditions (N = 59) compared their self-created task solution with a partly correct solution presented additionally, deviating from their solution. The other solution’s source was introduced either as a low status source (“peer”) or as a high status source (“textbook”) whereas the presented solution was identical. In a baseline condition, this comparison possibility was missing. Students in the textbook condition experienced more socio-cognitive conflict and adapted their solution more often to the correct aspect of the presented solution than students in the peer condition. Students low in social comparison orientation adapted their solution more extensively in the textbook condition than in the peer condition.
