What makes a word so attractive? Disclosing the urge to read while bisecting

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Expert readers demonstrate systematic leftward shifts in visual bisection (pseudoneglect) and cross-over effects with orthographic stimuli.
• These phenomena are linked to asymmetrical attention allocation during visuo-verbal processing and lexical access.

Purpose of the Study:

• To investigate the specific visual features that guide the recognition of potentially orthographic materials.
• To disentangle the roles of orthography, heterogeneity, and visuo-perceptual discreteness in visual scanning mechanisms.

Main Methods:

• Utilized the bisection paradigm with Italian unimpaired adults across four experiments.
• Presented stimuli varying in discreteness and heterogeneity to assess their impact on visual processing.

Main Results:

• A cross-over effect was observed in most discrete strings, particularly those with heterogeneous elements suggestive of orthographic relevance.
• This effect consistently appeared in the processing of letter strings and words, irrespective of visual discreteness.

Conclusions:

• Neither visual discreteness nor heterogeneity alone fully explains the activation of text-exploration scanning mechanisms.
• Both factors contribute to the likelihood of a visual stimulus undergoing pre-lexical processing, influencing visual scanning behavior.
