How do we acquire expertise and what fails us?
How is expert’s performance different from the novice or mildly experienced performer? I will make a case for expertise acquisition as a switch in the underlying mechanisms from on-line computations to mostly scheme based performance. This switch is attained when basic task-relevant regularities can be successfully detected and stored in posterior, perceptual areas of the neo-cortex. This “backsourcing” processes transforms cognitive-based performance to perception based. I will give examples from simple auditory discriminations to complex reading acquisition, and their relative failure in the case of dyslexia.
