“…The decibel level at which the auditory stimuli were presented was adjusted individually for each participant at the beginning of the experiment, in order to be clearly audible but not unpleasant. The individual decibel level for each participant was recorded, and it ranged from 60 to 75 dB, which is within the range used by previous studies (see e.g., [ 2 , 3 , 14 , 22 ]).…”

“…If, however, a spatially congruent auditory cue is presented, visual attention is oriented to the perceived origin of the cue, aligning the fovea with the latter [ 3 ]. Thus, the spatial auditory cue limits the effective extent of the visual search field, and enhances visual attentional processing in the cued area, which results in an improved target detection performance [ 13 , 14 ]. If, however, the spatial origin of the auditory cue and the position of the visual target do not coincide, attention has to first be disengaged from the incorrectly cued location and shifted (i.e., reoriented) to the target location, which results in an impaired target detection performance (e.g., [ 2 , 13 , 15 ]).…”

Attentional reorienting triggers spatial asymmetries in a search task with cross-modal spatial cueing

Cross-modal spatial cueing can affect performance in a visual search task. For example, search performance improves if a visual target and an auditory cue originate from the same spatial location, and it deteriorates if they originate from different locations. Moreover, it has recently been postulated that multisensory settings, i.e., experimental settings, in which critical stimuli are concurrently presented in different sensory modalities (e.g., visual and auditory), may trigger asymmetries in visuospatial attention. Thereby, a facilitation has been observed for visual stimuli presented in the right compared to the left visual space. However, it remains unclear whether auditory cueing of attention differentially affects search performance in the left and the right hemifields in audio-visual search tasks. The present study investigated whether spatial asymmetries would occur in a search task with cross-modal spatial cueing. Participants completed a visual search task that contained no auditory cues (i.e., unimodal visual condition), spatially congruent, spatially incongruent, and spatially non-informative auditory cues. To further assess participants’ accuracy in localising the auditory cues, a unimodal auditory spatial localisation task was also administered. The results demonstrated no left/right asymmetries in the unimodal visual search condition. Both an additional incongruent, as well as a spatially non-informative, auditory cue resulted in lateral asymmetries. Thereby, search times were increased for targets presented in the left compared to the right hemifield. No such spatial asymmetry was observed in the congruent condition. However, participants’ performance in the congruent condition was modulated by their tone localisation accuracy. The findings of the present study demonstrate that spatial asymmetries in multisensory processing depend on the validity of the cross-modal cues, and occur under specific attentional conditions, i.e., when visual attention has to be reoriented towards the left hemifield.

“…Visual stimuli and visual search task. Previous studies using spatialized auditory and audio-tactile cues have been conducted in the Auditory Localization Facility (ALF) of the AFRL/WPAFB, which is a physical geodesic sphere suspended within an anechoic chamber, used for conducting research on spatial audition (e.g., Haggit, 2014;Mateo et al, 2012). In order to ensure comparability of outcomes between physical-and virtual-worlds, we created the experimental virtual space to contain a sphere with the same radius (2.3 m) as ALF.…”

“…Recent research has shown the benefits of providing spatial information via multimodal cueing, particularly using spatialized auditory displays (e.g., Simpson, Brungart, Dallman, Joffrion, Presnar, & Gilkey, 2005). Whereas researchers have conducted studies in two-dimensional dynamic environments (e.g., McIntire, Havig, Watamaniuk, & Gilkey 2010) or three-dimensional static environments (e.g., Mateo, Simpson, Gilkey, Iyer, & Brungart, 2012), they have not examined the benefits of display types in threedimensional (360-degree) and dynamic (moving) environments. And yet, dimensionality and movement are fundamental components of applied visual search tasks, such as pilots searching for other airborne aircraft.…”

Maintaining spatial awareness is a primary concern for operators, but relying only on visual displays can cause visual system overload and lead to performance decrements. Our study examined the benefits of providing spatialized auditory cues for maintaining visual awareness as a method of combating visual system overload. We examined visual search performance of seven participants in an immersive, dynamic (moving), three-dimensional, virtual reality environment both with no cues, non-masked, spatialized auditory cues, and masked, spatialized auditory cues. Results indicated a significant reduction in visual search time from the no-cue condition when either auditory cue type was presented, with the masked auditory condition slower. The results of this study can inform attempts to improve visual search performance in operational environments, such as determining appropriate display types for providing spatial information.
