Abstract

fetched live from OpenAlex

After lesions to primary visual cortex, patients lack conscious awareness of visual stimuli. Interestingly, however, some retain the ability to make accurate judgments about the visual world (i.e., so-called blindsight). Similarly, damage to inferior occipitotemporal regions of cortex (e.g., lateral occipital cortex) can result in an inability to perceive object properties while retaining the ability to act on them (i.e., visual form agnosia). In the present work, we demonstrate that the ability to interact with objects in the absence of conscious awareness is not isolated to those with restricted neuropathologic conditions. Specifically, neurologically intact individuals are able to program and execute goal-directed reaching movements to a target object without awareness of extrinsic target properties; they accurately tune the dynamics of their movement and modulate it online without conscious access to features of the goal object. Thus, the planning and execution of actions are not dependent on conscious awareness of the environment, suggesting that the phenomenon of blindsight (and agnosia) reflect normal conditions of the visual system.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
