title: Fluctuations in pre-trial attentional state and their influence on goal neglect.
abstract: Fluctuations in attentional state and their relation to goal neglect were examined in the current study. Participants performed a variant of the Stroop task in which attentional state ratings were given prior to each trial. It was found that pre-trial attentional state ratings predicted subsequent trial performance, such that when participants rated their current attentional state as highly focused on the current task, performance tended to be high compared to when participants reported their current attentional state as being unfocused on the current task. This effect was larger for incongruent than congruent trials leading to differences in the magnitude of the Stroop effect as a function of pre-trial attentional state. Furthermore, variability in attentional state was correlated with overall levels of performance, and when attentional state was covaried out, the Stroop effect was greatly reduced. These results suggest a link between fluctuations in pre-trial attentional state and goal neglect.
