The provided sources investigate the effects of visual distractors and cognitive mechanisms of distraction, but do not establish that specific neurophysiological mechanisms are consistently associated with it.
<h4>Introduction</h4>This study investigates the effects of visual distractors in virtual reality (VR) environments on sustained attention, focusing on how visual distraction modulates neural mechanisms of attentional allocation and regulation.<h4>Methods</h4>Behavioral and electroencephalographic (EEG) data were collected from 66 participants performing a Go/No-go continuous performance test (CPT) in a virtual classroom under conditions with (Y-D) and without (N-D) visual distractors. We analyzed behavioral performance (commission/omission errors, multipress, reaction time), event-related potential (P300) characteristics (latency, amplitude), and nonlinear dynamics (sample entropy, fuzzy entropy) of the EEG signals.<h4>Results</h4>Behavioral results revealed that visual distractors significantly increased commission errors, omission errors, and multipress (all <i>p</i> < 0.001), with no significant difference in reaction time. EEG analysis demonstrated that distractors significantly prolonged P300 latency, particularly at CPz, Pz, and Oz electrodes, and increased P300 amplitude at Fz, FCz, and Oz. Furthermore, both sample entropy and fuzzy entropy values were significantly higher under distraction conditions in the frontal, central, and parietal regions.<h4>Discussion</h4>These findings indicate that visual distractors disrupt cognitive processes related to visual information integration, attentional control, and decision-making, leading to decreased behavioral performance and increased neural complexity. This study deepens the understanding of the neural mechanisms of attention processing under ecological conditions and provides a scientific basis for optimizing educational environments and developing attention assessment tools based on neuroengineering.
raction is presented in Figure 1 . At the beginning, we have a primary task that needs to be focused on while we perceive all kinds of task-irrelevant distractions in the surrounding environment, including different types of sensory stimuli and task-unrelated thoughts generated within our minds ( Kandel et al., 2021 ; Wong et al., 2022 ). As we focused on our primary task, certain distractions are resisted within the distraction capacity and have no distractive influence on task performance. Such cognitive system explains how focused attention can be achieved and how the distractive influence of certain distractions is resisted. However, not all distractions can be continuously resisted by distraction capacity. The distractive influence of certain distractions may exceed the distraction capacity, inevitably leading to the conscious awareness of being distracted. Then the attention control system is involved for actively determining whether to ignore this distraction and re-focusing on primary task or relinquishing our focused attention on task and indulging our attention to focus on the perceived distraction. Deciding to re-focus on primary task represents the success of controlling attention and resisting distraction, whereas shifting attention to distraction is a representation of failing to control attention and resist distraction.

The cognitive process of distraction. Meanwhile, it is extremely important to note that the premise of proposed cognitive process of distraction, which is actively focusing on the primary task. In other words, distraction is only a problem when we need to achieve focused attention on a task. Otherwise, as Eyal (2019) mentioned, you cannot be distracted if you are entertaining. Without the need to focus on a task, the problem of distraction ceases to exist. Therefore, having such a premise is indispensable for understanding the cognitive process of distraction.
