The aims of the current research programme were, first, to examine expertise effects with regard to anticipation skill and the perception of deceptive movement, and, second, to examine how knowledge of the probability of behavioural events influences anticipation performance and visual search behaviour. In addition, this thesis sought to test the predictions of attentional control theory (ACT) in examining how anxiety affects the influence of top-down probability information on anticipation skill and visual search behaviour. In Chapter 3, skill-based differences in anticipation and decision making were examined using judgement accuracy and confidence ratings. High-skilled soccer players demonstrated superior anticipatory performance and were less susceptible to deception compared with low-skilled players. In Chapters 4 and 5 Posner’s spatial cueing paradigm was adapted to examine the influence of top-down probability information on anticipation skill and visual search behaviour. High-skilled participants were found to be more accurate and demonstrate more efficient visual search behaviour compared to low-skilled participants. However, findings demonstrated that both groups benefited from the provision of probability information, and performance was moderated by the degree of certainty conveyed through the probability information. In Chapter 6, the same anticipation task and process tracing measures were used to examine the effects of heightened anxiety on the processing of probability and visual information. The findings supported the predictions of ACT, as the influence of top-down information was suppressed during high-pressure conditions, owing to an increased influence of the stimulus-driven attentional control system. The series of studies in this thesis are the first to explore the influence of top-down probability information on anticipation performance and the perception of deception. Study 4 is also the first to test the predictions of ACT regarding the processing of (top-down) explicit knowledge and (bottom-up) visual information under pressure during a simulated soccer anticipation task. The use of probability information through performance analysis feedback plays a prominent role across a number of sports, and the present findings highlight the importance of understanding the costs and benefits associated with such information. It is concluded that future perceptual training interventions should incorporate context-specific information that mimics the real-life demands of competitive sport, and should be directed towards enhancing players' ability to detect deception rather than training players to become attuned to non-deceptive movement.
