Measuring attention and vigilance in the laboratory vs. online: The split-half reliability of the ANTI-Vea

Abstract

Over the past few years, there has been growing interest in using online methods for collecting data from large samples. However, only a few studies have administered online behavioral tasks to assess attention outside the lab. In the present study, we assessed the classic attentional functions and two vigilance components using two versions of the Attentional Networks Test for Interactions and Vigilance-executive and arousal vigilance components (ANTI-Vea): (1) a standard version, performed under typical experimental conditions (n = 314), and (2) an online version, completed outside the lab (n = 303). Both versions were equally effective in assessing (1) the main effects and interactions of phasic alertness, orienting, and executive control, and (2) the executive (i.e., a decline in the ability to detect infrequent critical signals) and the arousal (i.e., a progressive slowness and variability in responses to stimuli from the environment) vigilance decrement across time on task. Responses were generally slower in the online than in the standard version. Importantly, the split-half reliability observed for both tasks was (1) higher for executive control (~.67) than for phasic alertness and orienting (< .40), as observed in previous versions of the task, and (2) between .71 and .99 for the executive and arousal vigilance measures. We expect the present study will be of interest to researchers aiming to assess attentional functions with a valid and reliable method that, importantly, is publicly available on an open website ( https://www.ugr.es/~neurocog/ANTI/ ) and is easy to use in applied contexts.
