“…We previously reported early target detection in tasks involving prolonged fixations when participants were asked to detect a subtle change in a synthetic stimulus (Kamienkowski et al, 2012) or when naturally looking for a face in a crowded scene, that is, producing fixations in the order of 200–250 ms (Kamienkowski et al, 2018), but not when they were instructed to prioritise accuracy in each fixation over time, producing longer fixations to avoid missing the target (Kaunitz et al, 2014). This is also consistent with studies reporting that target identification can be detected from the EEG signal prior to fixation onset (Dias et al, 2013; Stankov et al, 2021).…”

“…The system identification approach taken here has focused on a continuous feature of the stimulus. But the same approach can be used if one is interested instead in responses to discrete events in time (Dimigen & Ehinger, 2021; Gonçalves et al, 2014; Stankov et al, 2021). What was new here is that the continuous feature was resolved in visual space, which in the present task also carried semantic meaning.…”

It is well established that neural responses to visual stimuli are enhanced at select locations in the visual field. Although spatial selectivity and the effects of spatial attention are well understood for discrete tasks (e.g. visual cueing), little is known for naturalistic experience that involves continuous dynamic visual stimuli (e.g. driving). Here, we assess the strength of neural responses across the visual space during a kart‐race game. Given the varying relevance of visual location in this task, we hypothesized that the strength of neural responses to movement will vary across the visual field, and it would differ between active play and passive viewing. To test this, we measure the correlation strength of scalp‐evoked potentials with optical flow magnitude at individual locations on the screen. We find that neural responses are strongly correlated at task‐relevant locations in visual space, extending beyond the focus of overt attention. Although the driver's gaze is directed upon the heading direction at the centre of the screen, neural responses were robust at the peripheral areas (e.g. roads and surrounding buildings). Importantly, neural responses to visual movement are broadly distributed across the scalp, with visual spatial selectivity differing across electrode locations. Moreover, during active gameplay, neural responses are enhanced at select locations in the visual space. Conventionally, spatial selectivity of neural response has been interpreted as an attentional gain mechanism. In the present study, the data suggest that different brain areas focus attention on different portions of the visual field that are task‐relevant, beyond the focus of overt attention.

“…Visual search is a common daily behavior; for example, recognizing a street sign in a busy cityscape. Experimentally, this behavior has been explored through various tasks like finding a target letter among a set of other letters ( Horowitz and Wolfe, 1998 ; Höfler et al, 2014 ), identifying a word on a list ( Lawrence, 1971 ; Radhakrishnan et al, 2022 ), or locating one specific image among a collection of images ( Yang and Zelinsky, 2009 ; Höfler and Hübel, 2018 ; Stankov et al, 2021 ).…”

Visual search, the process of trying to find a target presented among distractors, is a much-studied cognitive task. Less well-studied is the condition in which the search task is interrupted before the target is found. The consequences of such interruptions in visual search have been investigated across various disciplines, which has resulted in diverse and at times contradictory findings. The aim of this systematic review is to provide a more cohesive understanding of the effects of interruptions in visual search. For this purpose, we identified 28 studies that met our inclusion criteria. To facilitate a more organized and comprehensive analysis, we grouped the studies based on three dimensions: the search environment, the interruption aftermath, and the type of the interrupting event. While interruptions in visual search are variable and manifest differently across studies, our review provides a foundational scheme for a more cohesive understanding of the subject. This categorization serves as a starting point for exploring potential future directions, which we delineate in our conclusions.
