Availability of advance visual information constrains association-football goalkeeping performance during penalty kicks

A pressing concern within the literature on anticipatory perceptual-motor behaviour is the lack of clarity on the applicability of data, observed under video-simulation task constraints, to actual performance in which actions are coupled to perception, as captured during in-situ experimental conditions. We developed an in-situ experimental paradigm which manipulated the duration of anticipatory visual information from a penalty taker's actions to examine experienced goalkeepers' vulnerability to deception for the penalty kick in association football. Irrespective of the penalty taker's kick strategy, goalkeepers initiated movement responses earlier across consecutively earlier presentation points. Overall goalkeeping performance was better in non-deception trials than in deception conditions. In deception trials, the kinematic information presented up until the penalty taker initiated his/her kicking action had a negative effect on goalkeepers' performance. It is concluded that goalkeepers are likely to benefit from not anticipating a penalty taker's performance outcome based on information from the run-up, in preference to later information that emerges just before the initiation of the penalty taker's kicking action.     

The role of movement exaggeration in the anticipation of deceptive soccer penalty kicks

Human movement containing deception about the true outcome is thought to be perceived differently compared to the non‐deceptive version. Exaggeration in the movement is thought to change the perceiver's mode of functioning from an invariant to a cue‐based mode. We tested these ideas by examining anticipation in skilled and less skilled soccer players while they viewed temporally occluded (?240 ms, ?160 ms, ?80 ms, 0 ms, +80 ms) deceptive, non‐deceptive, and non‐deceptive‐exaggerated penalty kicks. Kinematic analyses were used to ascertain that the kicking actions differed across conditions. The accuracy of judging the direction of an opponent's kick as well as response confidence were recorded. Players were over confident when anticipating deceptive penalty kicks compared to non‐deceptive kicks, suggesting a cue‐based mode was used. Furthermore, there was a significant relationship between less skilled players’ confidence ratings and their accuracy 80 ms before ball‐foot contact in the deceptive and non‐deceptive‐exaggerated conditions, but not the non‐deceptive condition. Because both deceptive and non‐deceptive‐exaggerated kicks contained exaggeration, results suggest exaggerated movements in the kickers’ action at 80 ms before ball‐foot contact explains why a cue‐based mode prevails when anticipating deceptive kicks at this time point.     

“Get it out the way. The wait's killing me.” hastening and hiding during soccer penalty kicks

ObjectivesIt has been suggested that hastening and hiding—rushing through penalty preparation and not looking at the goal when preparing the penalty kick—are associated with negative penalty taking performance. In the present study, we investigated how opposing players perceived these nonverbal behaviors, how they affect outcome expectations, and how they affect the behavior of opposing goalkeepers.DesignThe present study employs an experimental research design (Experiment 1: 2 (gaze behavior) × 3 (preparation time) design; Experiment 2: 2 (gaze behavior) × 2 (preparation time) design).MethodWe examined the perception of nonverbal hastening and hiding behavior using the point-light technique during the soccer penalty kick among goalkeepers (Experiment 1a; n = 20), and among outfield soccer players (Experiment 1b; n = 29). Furthermore, we analyzed how these respective penalty preparation strategies influenced the behavior of high-level goalkeepers (n = 12) under in situ conditions (Experiment 2).ResultsThe results from Experiment 1 demonstrated that penalty takers showing hastening and hiding behaviors are perceived more negatively by both soccer goalkeepers and outfield players: (i) they are considered to possess less positive attributes, (ii) to have less accuracy in their penalties, and (iii) likely to perform less well in penalty situations. Experiment 2 provided first evidence that goalkeepers initiate their movement later following the observation of hastening and hiding behaviors during the penalty preparation.ConclusionsOur findings demonstrate the importance of investigating nonverbal behavior in sports as these have a major impact on impression formation, expected performance, and actual behavior of opposing players in the soccer penalty situation.     

Studying the effects of self-talk on thought content with male adult tennis players

The current study examined the effects of self-talk on thought content during a tennis forehand crosscourt exercise. 16 adult tennis players (M age = 37.3 yr., SD = 8.31) were randomly assigned to either an experimental or a control group. After completing three baseline assessments, the players of the intervention group developed and implemented self-determined instructional cue words throughout three intervention trials. The participants' thought content was divided into three categories, and repeated-measures analyses of variance indicated a significant group by time interaction for execution-related thoughts and outcome-related thoughts, but not for circumstance-related thoughts. Follow-up comparisons showed that the experimental group players' execution-related thoughts increased and outcome-related thoughts decreased significantly, whereas thought content did not change significantly in the control group. The results of this study provided evidence for the effects of self-talk on players' thought content and supported the idea that self-talk could help athletes to focus on task relevant information.     

Effect of verbal cueing on trajectory anticipation in the penalty kick among novice football goalkeepers

The effect of a cueing technique on novice goalkeepers' anticipation of trajectory in penalty kicks was investigated. 28 novice football goalkeepers from junior teams were randomly selected and divided into experimental (n = 14) and control (n = 14) groups. Following a pre-test, participants performed 30 trials of a simulated penalty-kicking task in a spatially occluded condition. They were required to react to penalty kicks and were informed of their performance in anticipating the direction in which the ball was kicked. The experimental group received cues about the position of the non-kicking foot of the kicker, but the control group did not. The two-way analysis of variance showed the significant main effects of blocks of trials and group, but the interaction was not significant. The experimental group more accurately anticipated the direction of the penalty kicks than the control group. The cueing technique benefited the novice goalkeepers in anticipating the direction of penalty kicks, due to the informative nature of the cue for skill execution.     

Differential effects of task-specific practice on performance in a simulated penalty kick under high-pressure

ObjectivesThe current study investigated to what extent task-specific practice can help reduce the adverse effects of high-pressure on performance in a simulated penalty kick task. Based on the assumption that practice attenuates the required attentional resources, it was hypothesized that task-specific practice would enhance resilience against high-pressure.MethodParticipants practiced a simulated penalty kick in which they had to move a lever to the side opposite to the goalkeeper's dive. The goalkeeper moved at different times before ball-contact.DesignBefore and after task-specific practice, participants were tested on the same task both under low- and high-pressure conditions.ResultsBefore practice, performance of all participants worsened under high-pressure; however, whereas one group of participants merely required more time to correctly respond to the goalkeeper movement and showed a typical logistic relation between the percentage of correct responses and the time available to respond, a second group of participants showed a linear relationship between the percentage of correct responses and the time available to respond. This implies that they tended to make systematic errors for the shortest times available. Practice eliminated the debilitating effects of high-pressure in the former group, whereas in the latter group high-pressure continued to negatively affect performance.ConclusionsTask-specific practice increased resilience to high-pressure. However, the effect was a function of how participants responded initially to high-pressure, that is, prior to practice. The results are discussed within the framework of attentional control theory (ACT).     

Short cue presentations encourage advance task preparation: a recipe to diminish the residual switch cost

In the task-switching literature, it has frequently been demonstrated that although advance task preparation reduces the switch cost, it never really eliminates the switch cost. This remaining residual switch cost received much attention, and it has been argued that advance preparation is restricted in nature. In the present study, the role of task-cue presentation in the establishment of the residual switch cost was investigated. In 4 experiments, the cue was removed during the preparation interval, and it was hypothesized that this would encourage participants to complete advance task preparation. The results of all 4 experiments provided support for this hypothesis: When the cue was presented for a short time and then removed, the residual switch cost completely disappeared. This was found for different cue types. Furthermore, Experiment 3 demonstrated that it was not the presence of the cue itself but merely differences in advance task preparation that caused the effects. This suggests that advance task preparation is not as restricted in nature as previously assumed.     

The power of nonverbal behavior: Penalty-takers’ body language influences impression formation and anticipation performance in goalkeepers in a simulated soccer penalty task

Previous research showed that penalty-takers’ body language affects the impressions goalkeepers form about them. Furthermore, it is often assumed that body language influences goalkeepers’ performance. However, as yet, there is no empirical evidence that indicates whether this latter effect exists. The present research was aimed at (1) replicating and offering more insight in the initial impression formation effects (Experiment 1-3) and (2) providing evidence that signals of dominance and submissiveness affect participants’ anticipation performance within a simulated soccer penalty task (Experiment 3). We report three experiments demonstrating that participants form more positive impressions and have less confidence in saving penalty kicks from dominant penalty-takers (or scoring against dominant goalkeepers, Experiment 1) than submissive penalty-takers (goalkeepers). However, we did not find evidence that participants’ automatic associations with dominant and submissive players underlie these findings (Experiment 2). Finally, we demonstrate that anticipation of kick direction is influenced by penalty-takers’ body language (Experiment 3). Participants performed worse in the simulated soccer penalty task against dominant than submissive penalty-takers. No mediation of impression formation was found.     

Effects of threat cues on attentional shifting, disengagement and response slowing in anxious individuals

According to cognitive models of anxiety, attentional biases for threat may cause or maintain anxiety states. Previous research using spatial cueing tasks has been interpreted in terms of difficulty in disengaging attention from threat in anxious individuals, as indicated by contrasts of response times (RTs) from threat cue versus neutral cue trials. However, on spatial cueing tasks, differences in RT between threat cue and neutral cue trials may stem from a slowing effect of threat on RT, as well as effects on allocation of visuospatial attention. The present study examined the effects of threat cues on both attentional cueing and response slowing. High and low anxious individuals completed a central cue task, which assessed threat-related response slowing, and a spatial cueing task, which assessed attentional biases for angry, happy and neutral faces. Results indicated that interpretation of the anxiety-related bias for threat depended on whether the effect of response slowing was taken into account. The study illustrates an important problem in using the modified spatial cueing task to assess components of threat-related attentional bias. As this experimental method may reflect both threat-related attentional cueing and response slowing effects, it cannot be assumed to provide pure measures of shift or disengagement components of attention bias.     

A paradigm for exploring what the mind does while deciding what it should do.

One widespread belief about automatic mental processes is that, among other characteristics, they are involuntary. No initial conscious intent is necessary because such processing is stimulus initiated. This claim was studied in the context of a novel task-choice procedure in which subjects were informed as to which of two tasks they should perform on a letter string either well in advance of a target, or when the target appeared. The hypothesis that initial processing of the target occurs without intent predicts that the effect of contrast reduction will be absent when the task cue appears synchronously with the target. This is because initial processing of the target should be completed during the time taken to decode the task cue. The results are inconsistent with this account. Instead, they support an account in which functional target processing is delayed until the subject knows what the task is. Some directions for future investigations are noted.     

Modulation of the Spatial Extent of the Attentional Focus in High-level Volleyball Players

In this study, we explored the ability of first league professional volleyball players to modulate the allocation of attentional resources in the visual space by adapting the size of the attentional focus. Like Castiello and Umilta (1990), we employed an experimental procedure that is a variation of Posner's (1980) paradigm for exploring covert orienting of visuospatial attention. In a signalled reaction time task, a peripheral cue of varying size was presented unilaterally or bilaterally of a central fixation point, followed by a target at different stimulus onset asynchronies. The target could occur validly inside the cue or invalidly outside it with varying spatial relation to its boundary. Our results suggest that volleyball players are better able than controls to modulate the distribution of attentional resources within and around peripherally cued areas. Moreover, volleyball players seem to be able to flexibly adapt the gradient of attentional resources around the cued area, as would be expected from their sport practice.     

The role of eye‐gaze in understanding other minds

From an early age, infants are sensitive to eye‐gaze direction. This study examined Baron‐Cohen's (1994, 1995) claim that the ability to use eye‐gaze plays a crucial role in the child's developing understanding of other minds. Children aged 3 and 4 years participated in a face‐reading task, which assessed their capacity to infer mental states from a character's direction of eye‐gaze, and in a false‐belief task. As predicted, no child passed the false‐belief task without prior success on the face‐reading task. However, contrary to a central claim within Baron‐Cohen's model of mind‐reading, presentation of an eye‐gaze cue in the false‐belief task did not enhance children's performance. Furthermore, children did not solely rely on eye‐gaze as a cue, but used another directional cue (an arrow) in inferring a character's desire and intention. These results question the special role of eye‐gaze in the child's developing ability to mind‐read.     

Emotional modulation of attention orienting: A classical conditioning study

Emotional modulation of attention shifting was investigated in Posner's (1980) spatial orienting task by conditioning the attention cue to an aversive white noise. Prior to the attention task, the Conditioning group received a 90dB white noise unconditioned stimulus (UCS) contingent upon the frame-lit rectangle attention cue, while the Control group received non-contingent presentations. The Conditioning group evidenced greater skin conductance responses to the frame-lit rectangle in the conditioning phase, reflecting an electrodermal conditioned response. In the attention phase, the frame-lit rectangle served as the attention cue in the spatial orienting task. The Conditioning group showed equally fast reaction times (RTs) to targets presented outside the location of the cue as to targets at the same location as the cue, reflecting elimination of the cognitive cost usually involved in shifting attention. The Control group evidenced the regular cost of shifting attention away from the location of the cue. The Conditioning group also evidenced a larger N1-component with a parietal distribution of the event-related brain potentials to the cue and a larger N1-component at the frontal regions to targets presented outside the cued location. This suggests that both visual orienting to the cue and attention shifting from cue to target on invalid trials were amplified by the emotional salience attached to the cue through the classical conditioning procedure.     

On the cued activation of situational motivation

We examined the hypothesis that situational (or state) motivation can generalize from one situation to another via activation by associated cues. In an experimental setting, a neutral cue (a computer tone sequence) was paired repeatedly with controlling feedback. We then assessed the effect of presenting this conditioned cue during a subsequent task on participants’ motivation for that novel task. In two studies we found evidence that cued activation of controlledness significantly undermined participants’ self-determined motivation toward this subsequent task. These findings demonstrate that subtle cues, including contextual primes, can influence people’s motivational state.     

Examination of gaze behaviors under in situ and video simulation task constraints reveals differences in information pickup for perception and action

Queensland University of Technology, Brisbane, Queensland, Australia Gaze and movement behaviors of association football goalkeepers were compared under two video simulation conditions (i.e., verbal and joystick movement responses) and three in situ conditions (i.e., verbal, simplified body movement, and interceptive response). The results showed that the goalkeepers spent more time fixating on information from the penalty kick taker’s movements than ball location for all perceptual judgment conditions involving limited movement (i.e., verbal responses, joystick movement, and simplified body movement). In contrast, an equivalent amount of time was spent fixating on the penalty taker’s relative motions and the ball location for the in situ interception condition, which required the goalkeepers to attempt to make penalty saves. The data suggest that gaze and movement behaviors function differently, depending on the experimental task constraints selected for empirical investigations. These findings highlight the need for research on perceptual— motor behaviors to be conducted in representative experimental conditions to allow appropriate generalization of conclusions to performance environments.     

The obligation to succeed when it matters the most–The influence of skill and pressure on the success in football penalty kicks

In order to gain a more comprehensive understanding of the influence of skill and pressure on the success in football penalty kicks, we analyzed 1711 penalties taken over a 15-year period in major international tournaments. We conducted a multiple correspondence analysis in order to reduce six variables that are associated with skill and pressure to two dimensions that reflect our target concepts. Then, we used these two factors as independent variables in a logistic regression and fit different models using three binary dependent variables. The results show that high situational pressure significantly increases the probability of missing the goal entirely by about 6%, independent of the player’s skill level. The probability that the goalkeeper saves a penalty significantly decreases by roughly 4% when a highly skilled player takes the shot. In general, high situational pressure decreases the probability of scoring a penalty kick. Furthermore, the probability to score a penalty increases if a highly skilled player takes the kick which indicates that a high skill level can act as a kind of buffer against debilitating effects caused by performance pressure.     

Effects of public posting,goal setting,and oral feedback on the skills of female soccer players

We evaluated the effects of public posting, goal setting, and oral feedback on the skills of 3 female high school soccer players during practice scrimmages. The dependent variables were the percentage of appropriate responses when the player (a) kept and maintained possession of the ball, (b) moved to an open position during a game restart (e.g., goal or corner kick), and (c) moved to an open position after passing the ball. We also assessed the extent to which changes in practice performances generalized to games. A social validity questionnaire was completed by both players and coaches to assess the acceptability of the intervention's goals, procedures, and outcomes. Results indicate that the intervention was effective in improving performances during practice scrimmages but produced limited generalization to game settings.     

The relationship between expertise and visual search strategy in a racquet sport

The visual search characteristics of 15 expert and 16 novice badminton players were recorded as they performed a film test designed to assess their anticipatory cue usage. Experts were found, from the film task, to be able to pick up earlier advance information than novices and this appeared to be related to their reliance upon the arm, in addition to the racquet, as a source of anticipatory information. These differemces in information-extraction, however, were not matched by differences in visual search characteristics with the location, duration and sequence of the novices' fixations on the film display being indistinguishable from those of the experts. It is concluded therefore that the major source of expertise-related differences in sport perception is not the visual search (or reception) strategy per se but rather the use to which the received information is subsequently put. Some experimental and practical implications of the observed discrepancy between visual orientation and information-extraction are considered and the normal search strategy adopted in badminton by both expert and novice players is described in some detail.     

Dissociating the components of switch cost using two-to-two cue-task mapping

In the task switch paradigm, a switch of task is typically accompanied by a change in task cue. It has been proposed that the performance deficit usually observed when switching tasks is actually the result of changing cues. To test this possibility, we used a 2:2 cue-task mapping in which each cue indicated 2 different tasks. With advance presentation of a cue, the cost associated with changing cues disappeared, though a substantial task switch cost remained. Without advance cues, the relative contributions of task switch cost and cue change cost differed by transition frequencies. The results suggest that task execution contributes to switch cost independent of cue changes.
