Quiet-eye training for soccer penalty kicks

Anxiety has been shown to disrupt visual attention, visuomotor control and subsequent shot location in soccer penalty kicks. However, optimal visual attention has been trained in other far aiming skills, improving performance and resistance to pressure. We therefore asked a team of ten university soccer players to follow a quiet eye (QE; Vickers 1996) training program, designed to align gaze with aiming intention to optimal scoring zones, over a 7-week period. Performance and gaze parameters were compared to a placebo group (ten players) who received no instruction, but practiced the same number of penalty kicks over the same time frame. Results from a retention test indicated that the QE-trained group had more effective visual attentional control, were significantly more accurate, and had 50% fewer shots saved by the goalkeeper than the placebo group. Both groups then competed in a penalty shootout to explore the influence of anxiety on attentional control and shooting accuracy. Under the pressure of the shootout, the QE-trained group failed to maintain their accuracy advantage, despite maintaining more distal aiming fixations of longer duration. The results therefore provide only partial support for the effectiveness of brief QE training interventions for experienced performers.     

Peer-based control in self-managing teams: linking rational and normative influence with individual and group performance

The authors use a multilevel framework to introduce peer-based control as a motivational state that emerges in self-managing teams. The authors specifically describe how peer-based rational control, which is defined as team members perceiving the distribution of economic rewards as dependent on input from teammates, extends and interacts with the more commonly studied normative control force of group cohesion to explain both individual and collective performance in teams. On the basis of data from 587 factory workers in 45 self-managing teams at 3 organizations, peer-based rational control corresponded with higher performance for both individuals and collective teams. Results further demonstrated that the rational and normative mechanism of peer-based control interacted to explain performance at both the individual and team levels. Increased peer-based rational control corresponded with higher individual and collective performance in teams with low cohesion, but the positive effects on performance were attenuated in cohesive teams.     

On the Ternary Relation and Conditionality

One of the most dominant approaches to semantics for relevant (and many paraconsistent) logics is the Routley?CMeyer semantics involving a ternary relation on points. To some (many?), this ternary relation has seemed like a technical trick devoid of an intuitively appealing philosophical story that connects it up with conditionality in general. In this paper, we respond to this worry by providing three different philosophical accounts of the ternary relation that correspond to three conceptions of conditionality. We close by briefly discussing a general conception of conditionality that may unify the three given conceptions.     

Neurobiological correlates of cognitions in fear and anxiety: a cognitive-neurobiological information-processing model

We review likely neurobiological substrates of cognitions related to fear and anxiety. Cognitive processes are linked to abnormal early activity reflecting hypervigilance in subcortical networks involving the amygdala, hippocampus, and insular cortex, and later recruitment of cortical regulatory resources, including activation of the anterior cingulate cortex and prefrontal cortex to implement avoidant response strategies. Based on this evidence, we present a cognitive-neurobiological information-processing model of fear and anxiety, linking distinct brain structures to specific stages of information processing of perceived threat.     

Wishing for Change in Japan and Canada

Japanese and Canadian university students were compared on the changes they wanted in their lives. Contrary to their characterization as self-effacingly relational and group-minded, Japanese were no more likely than Canadians to wish for social or collective goods. Rather, Japanese were more likely than Canadians to wish for money or material goods, and less likely than Canadians to wish for better family relations, increased self-understanding, and improved academic performance. Whether these findings reflect dissimilar cultural priorities, unequal opportunities and constraints, or both, is discussed.
