Components of attentional effort for repeated tasks

Abstract

This paper identifies four attentional processes that increase efficiency and accuracy in repeated lexicographic tasks using an instructed strategy approach. We propose a framework to decompose attentional effort used to make a decision into four components: Orientation, Wrong Target, Duration, and Repetition. Orientation assesses attention to decision rules and the location of relevant information. Wrong Target measures wasted effort on unneeded information. Duration gauges time spent on each piece of needed information. Repetition measures the number of views on each relevant item. Greater Orientation is associated with lower effort in other components and increased accuracy. Repetition is most variable across individuals but generates the greatest improvement with practice. Duration is less affected by the other components and shows minimal improvement with experience. Finally, Wrong Target

Modeling Eye Movements During Decision Making: A Review

“…For example, visual factors, which have a large impact on choice decisions (Orquin et al, 2021 ), are typically absent. Extant models do not account for consecutive refixations on the same object (Chandon et al, 2009 ; Krajbich et al, 2010 ; Martinovici et al, 2021 ; Yang et al, 2015 ), which is a striking characteristic of scan-paths across a wide range of tasks (Liechty et al, 2003 ; Musalem, Montoya, Meißner, & Huber, 2021 ; Rayner, 1998 ; van der Lans et al, 2008b ).…”
