Alternatively, under the cognitive overload view, performing the SART requires constant monitoring over time, using executive resources, and as such inattentive individuals would be expected to report frequent spontaneous mind wandering, especially when the task is more difficult (when the digits are presented randomly) due to their limited working memory capacity 35 , 36 .…”
