Early visual deprivation in 34 Ethiopian children with bilateral congenital cataracts leaves global motion integration intact, but impairs attention-dependent motion coherence performance.
- Why it matters: Prior work linked global motion deficits to faulty integration of local motion signals, but it did not separate integration from attentional selection demands.
- What they did: Children were tested years after gaining pattern vision; they matched typically developing peers on direction-integration tasks modeled by population vector averaging, but were worse on motion-coherence tasks requiring a dominant direction.
- The result: A model adding attention-dependent top-down amplification explained the dissociation, and late sighted showed broader impairments across attention-demanding tasks, supporting disrupted attentional selection rather than impaired integration.
