✦ Synopsis

Three experiments examined the relative importance of attributes determined largely by the eciency of the visual/central nervous system versus cognitive domain-speci®c skills, in the determination of expertise in soccer. In Experiment 1, expert and intermediate soccer players were assessed on various non-speci®c abilities including: processing (simple reaction time, peripheral reaction time, visual correction time), optometric (static, dynamic and mesopic acuity), and perimetric parameters (horizontal and vertical peripheral range). In Experiment 2, domain-speci®c variables were assessed including complex decision speed and accuracy, number of visual ®xations, ®xation duration, and ®xation location in solving game problems. Stimuli were initially presented by slides (Experiment 2) and later by 16 mm ®lm (Experiment 3). Eye movements were recorded and analysed. A stepwise discriminant analysis of both non-speci®c abilities and soccer-speci®c skills revealed an average squared canonical correlation 0.84, with the signi®cant step variables all being domain-speci®c skills.

This review describes the use of frequency-selective filters for the design of selective NMR experiments. Frequency-selective filters constitute 'user-friendly' and efficient alternatives to selective excitation in most applications. Different selective schemes are discussed, which are based either

The Theory of Planned Behaviour was proposed by Ajzen (1985) in an attempt to expand the applicability of the Theory of Reasoned Action (TRA) to situations where behaviour is not under complete volitional control. However, recent research does not address the issue of the stability of intentions, ye
