Abstract

‘Butterfly effects’ in Perceptual development

How might atypicalities in early perceptual development impact later

proficiencies? We consider one sliver of what is likely to be a complex

and multifaceted answer. In the specific context of children who have been

created for congenital blindness, we and others have found some consistent

deficits in post-operative recognition performance. These deficits have

typically been attributed to the pre-operative deprivation the children

experienced during 'sensitive periods' of development. However, we suggest

that there may be an additional factor at work: Differences in

post-operative visual experiences of newly-sighted children relative to

those of typically developing infants. These differences may skew early

visual learning and lead to abnormalities in recognition processes. We

call these 'butterfly effects' given that they involve potentially large

consequences of small initial perturbations in visual experience. Such

hypothesized butterfly effects have relevance for three goals – accounting

for observed deficits in newly-sighted children, understanding why some

aspects of normal visual development unfold in the way they do, and

formulating effective training regimens for computational vision systems.
