Exploring the Role of Distraction in Weak Flow–Performance Link Based on VR Searching Tasks

Abstract

The weak association between flow experience and task performance (also known as weak flow-performance link) can reduce the positive effect of virtual reality (VR) applications. Distraction caused by incongruence between the primary task and interactive artifacts may be a direct factor leading to the weak link, but it has still not been tested. To empirically test this assumption and explore approaches to alleviate it, we developed the ‘VR searching paradigm’ and a prototype VR system, based on which three comparative experiments were conducted. Study 1 tested the effect of distraction and proved that high levels of distraction caused by incongruence can lead to the weak link (β =0.198, p = 0.391). Next, two common design guidelines were proposed to deal with distraction. Study 2 tested the effect of reducing conspicuous but task-irrelevant distractors (guideline 1) on flow-performance link. Study 3 tested the effect of providing visual cues (utilizing distractors to achieve task-oriented selective attention), which is guideline 2, on flow-performance link. The results of studies 2 and 3 revealed that both guidelines helped enhance the task performance without damaging flow experience, alleviating the weak link problem (β = 0.351, p = 0.031; β = 0.255, p = 0.041). Our results provide the first piece of evidence that directly proves the effect of distraction on weak flow-performance link, which helps improve the explanation of the mechanism. Moreover, this paper is the first that proves the effectiveness of two easy approaches to alleviating the weak link by way of guiding the user’s task-relevant attention.
