Effects of attentional strategies and anxiety constraints on perceptual-motor organisation of rhythmical arm movements
Court, Michael, Bennett, Simon J., Williams, Andrew M., & Davids, Keith W. (2005) Effects of attentional strategies and anxiety constraints on perceptual-motor organisation of rhythmical arm movements. Neuroscience Letters, 384(1-2), pp. 17-22.
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 (00) and anti-phase (1800) 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.
