Passive perceptual learning versus active searching in a novel stimuli vigilance task

Abstract: A criticism of laboratory vigilance or sustained attention research is the employment of static monotonous tasks with repetitive targets as opposed to the use of dynamic tasks with novel target stimuli. Unfortunately dynamic tasks employing novel stimuli may result in the mixture of two cognitive processes: active sustained attention search and passive perceptual learning. Moreover, the relative engagement of these two processes may depend on individual differences. In the present study, we examined this by ha… Show more

“…Our results agree with findings from a recent uncontrolled study that showed no change in unaided sustained auditory and sustained visual attention scores in children with APD following a 5-month RMHA intervention (Smart et al, 2018). Alternatively, the non-significant results in the Sus-AA subtest could potentially be explained by the mismatch between dynamic real-life sustained attention situations and monotonous lab-based sustained attention tasks (Head and Helton, 2015). Further RMHA intervention trials should investigate differential Sus-AA tasks with inclusion of dynamic linguistic stimuli similar to the ones that children come across in the classroom.…”

“…Indeed, this may have resulted in the A′ increase noted for this group. Increased cerebral activation has been found to predict improvements in performance in perceptual learning experiments (Ong et al 2013), and other researchers have noted concerns regarding the impact perceptual learning may have on vigilance tasks (Head and Helton 2015;Szalma et al 2004). It was expected that the circle condition would have the highest level of accuracy, followed by the reconnected condition, and the broken condition performing the worst.…”

“…There is potential that passive perceptual learning, where participants may passively learn search strategies throughout the vigil in order to become more efficient over time, influenced the trends found in the previous experiment; a possibility that was noted by the authors. It has been suggested in previous experiments that this improvement due to passive perceptual learning is greater in conditions that have a lower level of performance initially (Head & Helton, 2015). It was suggested that the previous improvement in the broken condition may have been due to this effect.…”

“…An initial increase in oxygenation is common when engaging in demanding tasks and an eventual decrease in oxygenation is not unexpected in a vigilance task (Bogler, Mehnert, Steinbrink & Haynes, 2014;de Joux et al, 2015a;de Joux et al, 2013;Derosière, Mandrick, Dray, Ward & Perrey, 2013;Hancock, 2015;Jeroski, Miller, Langhals & Tripp, 2014;Shaw et al, 2013). Researchers have noted that many vigilance tasks are often characterized by an early stage of passive perceptual learning (Ong, Russell, & Helton, 2013;Head & Helton, 2015). In this initial stage, frontal activation should be elevated and then activity should decline with experience with the task.…”
