Helsen, Gilis and Weston (2006) err in testing the optical error hypothesis
Full text linkIn this commentary, we react to the recent study by Helsen, Gilis and Weston (2006) on judging offside in football. Helsen et al. claim that their data falsify the optical error hypothesis presented by Oudejans et al. (2000). However, as we will elucidate here, they misinterpret this hypothesis and present a data set that is seriously flawed, and hence not suited to test it. Therefore, their conclusions regarding the optical error hypothesis are in error
Police performing and training under pressure
No full textItem does not contain fulltextIn this presentation, we will present our work with police officers. First, Oudejans (2008) found that reality based practice under pressure helps in preventing degradation of handgun shooting performance under pressure for police officers. The experimental group practiced handgun shooting under pressure evoked by an opponent who fired back using marking (coloured soap) cartridges.
The control group practiced shooting on standard cardboard targets. While at the outset both groups performed worse in front of an opponent firing back compared to cardboard targets, after training,
shooting performance of the experimental group no longer deteriorated while performance of the control group was still equally harmed. These results indicate that training under pressure can
acclimatize shooting performance of police officers to those highpressure situations they may encounter during their work. Yet, this study does not provide insights into more detailed changes in
behaviour that accompany or underlie changes in performance. Therefore, in a next (pilot) study we explored changes in shooting accuracy, movement times, head/body orientation, blink and gaze
behavior of police officers shooting under pressure. Results again showed that with pressure, shooting accuracy decreased. Furthermore, participants acted faster, had a different head/body orientation, made more blinks, and seemed to have higher search rates and decreased
durations of fixations on the targets. The pilot study is currently followed-up by a training study investigating the effects of training under pressure on the same variables. It is expected that the negative changes that were found under pressure will disappear
