Does framing an assignment as involving one or multiple components influence subjective experiences of attentional engagement?

Across two studies, we explored whether framing an assignment as involving either multitasking or single-tasking (Srna et al. Psychol Sci 29(12):1942-1955, 2018) leads to differences in both subjective ratings of attentional engagement (i.e., depth of concentration and attentional control) and performance during the assignment. In Experiment 1, we manipulated task framing in the context of an assignment in which participants (N = 238) simultaneously completed a word-search and an anagram task (Srna et al. Psychol Sci 29(12):1942-1955, 2018). While we replicated prior findings that participants who receive multitasking instructions perform better than those who receive single-tasking instructions, we did not find any influence of task framing on participants' subjective evaluations of their attentional engagement. Exploratory analyses, however, revealed that regardless of group assignment, those who believed they were multitasking reported greater levels of attentional engagement than those who believed they were single-tasking. In Experiment 2 (N = 238), task framing was varied in the context of the 2-back task (Kirchner J Exp Psychol 55(4): 352, 1958). Unexpectedly, we found that, relative to participants who received single-tasking instructions, those who received multitasking instructions reported exerting less attentional control over their thoughts and showed a greater number of incorrect responses to non-target trials on the 2-back. Taken together, the results do not support a straightforward conclusion regarding the influence of task framing on either subjective reports of attentional engagement or task performance. Nevertheless, they provide insight into our understanding of the role of task framing in contexts ranging from commonly performed real-world tasks to typical laboratory tasks.
