'Seeing' proximal representations: Testing attitudes to the relationship between vision and images

Area of Science:

• Cognitive Psychology
• Visual Perception

Background:

• The visual system applies corrections, such as size constancy, to maintain a stable perception despite varying retinal images.
• Understanding how individuals perceive visual information and whether they can treat their own vision as a 2D representation is crucial.

Purpose of the Study:

• To investigate adults' willingness to perceive their own vision as an uncorrected 2D image.
• To explore resistance to deconstructing visual stability and constancy.

Main Methods:

• Participants viewed two lines of equal physical length, one closer and thus appearing longer.
• Judgments were taken based on direct visual appearance and then based on a photograph of the lines.
• Responses regarding direct vision and photographic representation were compared.

Main Results:

• Approximately 50% of participants judged the lines as appearing the same length, despite instructions to focus on appearance.
• When judging a photograph, participants correctly identified the closer line as appearing longer.
• Participants reverted to judging their direct vision as stable when asked again, indicating resistance to the 2D image perspective.

Conclusions:

• Many adults demonstrate a strong resistance to conceptualizing their own visual experience as a flat, uncorrected 2D image.
• This resistance highlights the ingrained nature of visual constancy mechanisms and challenges in adopting a purely appearance-based perspective.
• Findings contribute to understanding visual perspective-taking and the perception of visual stability.
