The goalkeeper’s difficulty in the soccer penalty kick originates from the extreme spatiotemporal constraints of the situation. The present review claims that the current understanding is biased toward attributing a goalkeeper’s success in saving a penalty kick to perceptual–cognitive skill. To investigate the goalkeeper’s skill, researchers have often adopted video tasks. In doing so, they studied perceptual skill in isolation from action. We use affordance-based control theory to propose an alternative understanding and research methodology. We argue that goalkeepers in the penalty kick situation should regulate their actions in ways that sustain the perception of stoppability. To capture this, we outline the building blocks for a required lateral velocity model, in which the goalkeepers’ required actions are scaled to their maximum capabilities. In doing so, we provide new directions for research. Die Schwierigkeiten für den Fußballtorhüter beim Strafstoß beruhen auf den extremen räumlich-zeitlichen Einschränkungen der Situation. In der vorliegenden Übersicht postulieren wir eine Verzerrung der aktuellen Deutung dahingehend, dass der Erfolg eines Torhüters beim Parieren eines Strafstoßes der perzeptorisch-kognitiven Fertigkeit zugeschrieben wird. Zur Untersuchung der Fertigkeit des Torhüters werden häufig Videoaufgaben genutzt. Auf diese Weise wird die perzeptorische Fertigkeit isoliert von der Handlung betrachtet. Ausgehend von der Theorie der affordanzbasierten Kontrolle schlagen wir eine alternative Deutung und Forschungsmethodik vor. Wir argumentieren, dass Torhüter in der Strafstoßsituation ihre Handlungen so steuern sollten, dass die Wahrnehmung der Haltbarkeit aufrechterhalten bleibt. Zur Erfassung umreißen wir die Bausteine eines Modells der erforderlichen lateralen Geschwindigkeit, in dem die erforderlichen Handlungen der Torhüter auf ihr maximales Leistungsvermögen skaliert sind. Damit werden neue Forschungsimpulse gesetzt.
It is widely accepted that the sources of information used to guide interceptive actions depend on conflicting spatiotemporal task demands. However, there is a paucity of evidence that shows how information pick-up during interceptive actions is adapted to such conflicting constraints. The present study therefore examined the effects of systematic manipulations of spatiotemporal constraints on performance, timing and gaze in an in situ interceptive action. To this end, expert futsal goalkeepers faced penalty kicks taken from 10 m and 6 m. With the more lenient spatiotemporal constraints (i.e., kicks from 10 m), the goalkeepers saved more kicks, initiated their actions later, and looked longer toward ball relative to the penalty takers' body. Furthermore, analysis of gaze patterns showed that interindividual variations in information pick-up were related to the unfolding of the penalty taker's action, revealing a less variable, funnel-like gaze pattern toward the end of the action. These findings are interpreted to reflect that changes in spatiotemporal demands induce the differential use of information for the accurate control of interceptive actions. (PsycINFO Database Record

This study addressed the question whether coaches better allow athletes to self-control their decisions when under pressure or whether to impose a decision upon them. To this end, an experiment was conducted that manipulated the soccer kickers’ degree of control in decision-making. Two groups of elite under-19 soccer players (n = 18) took penalty kicks in a self-controlled (i.e., kickers themselves decided to which side to direct the ball) and an externally controlled condition (i.e., the decision to which side to direct the ball was imposed upon the kickers). One group performed the penalty kick under psychological pressure (i.e., the present coaching staff assessed their performance), while the second group performed without pressure. Just before and after performing the kicks, CSAI-2 was used to measure cognitive and somatic anxiety and self-confidence. Further, the number of goals scored, ball placement and speed, and the duration of preparatory and performatory behaviors were determined. The results verified increased levels of cognitive and somatic anxiety after performing the kicks in the pressured group compared to the no-pressure group. In addition, degree of self-control affected the participants’ performance, particularly in the pressured group. They scored more goals and placed the kicks higher in the self-controlled than in the externally-controlled condition. Participants also took more time preparing and performing the run-up in the self-controlled condition. Findings indicate that increased self-control helps coping with the debilitating effects of pressure and can counter performance deteriorations. The findings are discussed within the framework of self-control theories, and recommendations for practitioners and athletes are made.
Several recent studies have shown that the performance of a skill that involves acting on a goal object can influence one's judgment of the size of that object. The present study investigated this effect in an aviation context. Novice pilots were asked to perform a series of visual approach and landing manoeuvres in a flight simulator. After each landing, participants next performed a task in which runway size was judged for different simulated altitudes. Gaze behaviour and control stick kinematics were also analyzed. There were significant relationships between judged runway size and multiple action-related variables including touchdown velocity, time fixating the runway, and the magnitude and frequency of control inputs. These findings suggest that relationship between the perception of a target object and action is not solely determined by performance success or failure but rather involves a relationship between multiple variables that reflect the actor's ability.
