COURT, M, BENNETT, S, WILLIAMS, A and DAVIDS, K (2005). Effects of attentional strategies and anxiety constraints on perceptual-motor organisation of rhythmical arm movements. Neuroscience Letters, 384 (1-2), 17-22.Full text not available from this repository.
Effects of anxiety on perceptual-motor organisation of rhythmical forearm movements were examined using an interrupted time series design with staggered baselines. Participants were exposed to repeated baseline sessions interrupted with two anxiety-inducing sessions. Results showed that under moderate levels of anxiety, determined from CSAI-2 and heart rate data, phase relations between oscillating forearms became more stable in in-phase (0°) and anti-phase (180°) modes, although these patterns were not maintained in baseline sessions following the anxiety manipulation. Data were consistent with participants employing a strategy of allocating greater attentional effort in stabilizing preferred co-ordination patterns under anxiety-inducing conditions. Results suggest that anxiety can temporarily act as a source of behavioural information, leading to the re-parameterisation of participants’ intrinsic dynamics.
