Abstract

BACKGROUND: Previous research suggested that vigilance may moderate the functioning of other attentional components. However, vigilance is usually neglected when comparing the attentional functioning between groups of clinical and/or healthy participants. NEW METHOD: We combined data from several studies using the Attention Network Test for Interactions and Vigilance (ANTI-V), which includes a vigilance measure plus phasic alertness, orienting, and executive control scores. We estimated, for the first time, the reliability of the vigilance performance indices in the ANTI-V, by analyzing split-half correlations of 10,000 permutations of the trials. In addition, we tested whether a different attentional functioning would be found across the group of healthy participants varying in their vigilance performance, by using a considerably larger sample size (226 participants) than previous studies.

RESULTS: Vigilance indices were the most reliable among the different attentional scores. Regression models show an inverse relationship between vigilance and phasic alertness and executive control. COMPARISON WITH EXISTING METHODS: No previous study has analysed the reliability of the vigilance performance indices in the ANTI-V. In comparison with other ANT variations, the ANTI-V provides a reliable measure of vigilance together with the typical phasic alertness, orienting and executive control scores. In addition, we provide estimates, based on a large sample size, of the magnitude of the link between vigilance and other attentional functions.

CONCLUSIONS: When assessing the multiple functions of attention, the current study highlights the importance of measuring vigilance, which may modulate the functioning of other attentional components, such as phasic alertness or executive control.
