Visual Selective Behavior Can Be Triggered by a Feed-Forward Process

By analyzing the time course of reaction times in a masked natural scene categorization paradigm, it is shown that the human visual system can generate selective motor responses based on a single feed-forward pass and feedback loops do not appear to be mandatory for visual processing.

Effects of task requirements on rapid natural scene processing: from common sensory encoding to distinct decisional mechanisms.

A masking procedure was used to compare 4 tasks in which sensory, decisional, and motor aspects were systematically varied to suggest that the initial part of the sensory encoding relies on common and parallel processing across a large range of tasks, whether participants have to categorize the image or locate a target in 1 of 2 scenes.

The Time Course of Visual Processing: From Early Perception to Decision-Making

It is shown that visual categorization of a natural scene involves different mechanisms with different time courses: a perceptual, task-independent mechanism, followed by a task-related, category-independent process.

ULTRA RAPID FACE DETECTION IN NATURAL IMAGES : IMPLICATIONS FOR COMPUTATION IN THE VISUAL SYSTEM

New data are presented with the same task that show that face detection is even more efficient and it seems clear that only a feedforward pass through the visual pathways can be performed in so little time.

The time course of visual processing: Backward masking and natural scene categorisation

Timecourse of neural signatures of object recognition.

These results imply that the neural signatures of recognition have a substantially later and variable time of onset, compared to previous studies suggesting that the early, presentation-locked component of neural activity is correlated to recognition.

A Limit to the Speed of Processing in Ultra-Rapid Visual Categorization of Novel Natural Scenes

This rapid processing mode was seen with a wide range of visual complex images, challenging the idea that short reaction times can only be seen with simple visual stimuli and implying that highly automatic feed-forward mechanisms underlie a far greater proportion of the sophisticated image analysis needed for everyday vision than is generally assumed.
