A visual perception track enables most people to recognize objects at nearly the same time that a visual action track enables them to avoid bumping into the objects.This best illustrates

A) sequential processing.
B) change blindness.
C) dual processing.
D) blindsight.

Dual processing refers to the idea that our brain can process information both consciously and unconsciously at the same time. This is exactly what is happening in the scenario described in the question - the visual perception track is processing information about the object consciously, while the visual action track is processing information about how to avoid the object unconsciously. Sequential processing refers to the idea that we process information one step at a time, which is not what is happening in this scenario. Change blindness refers to the phenomenon where people fail to notice changes in their environment, which is not what is happening in this scenario either. Blindsight refers to the phenomenon where people with damage to the visual cortex are still able to perceive some aspects of their visual environment unconsciously, which is not what is happening in this scenario either.
