STAGE 1
Putting things into perspective: Which visual cues facilitate automatic extraretinal symmetry representation?
Understanding how visual cues influence extraretinal representation of planar symmetry
Recommended by Grace Edwards and Zoltan Dienes based on reviews by Tadamasa Sawada, Guillaume Rousselet, Benoit Cottereau and Deborah ApthorpVisual symmetry is critical to our interaction with our environment so that when detected, symmetry automatically produces a neural marker in the form of an Event Related Potential (ERP) called Sustained Posterior Negativity (SPN). However, when symmetry is presented to the visual system slanted away from the viewer, there is a reduction in SPN, termed a perspective cost.
Considering objects are rarely presented front-on (or frontoparallel) in our natural environment, Karakashevska et al., (2023) plan to examine the extent of the perspective cost with the addition of visual cues to facilitate extraretinal representation of the visual symmetry. The authors will record electroencephalography (EEG) from 120 participants while they perform a luminance task on symmetrical and asymmetrical stimuli. The authors hypothesize perspective cost will be reduced by three perspective cues: 1) monocular viewing, when cue conflict caused by binocular viewing is eliminated, 2) a static frame surrounding the symmetrical stimulus, adding a depth cue, and 3) a moving frame, assisting 3D perception prior to the symmetry onset. If the SPN is equivalent during frontoparallel and slanted presentation in a cue condition, the authors will conclude extraretinal representation can be automatic when sufficient visual cues are available. The proposed experiment is powered to detect a relatively small difference between perspective cue conditions. This will solidify fundamental research on visual symmetry processing and will further our understanding of object perception and recognition.
The Stage 1 manuscript was evaluated over three rounds by four expert reviewers. Following in-depth review and responses from the authors, the recommenders have determined that Stage 1 criteria was met and have awarded in-principle acceptance (IPA).
