Motion processing specialization in Williams Syndrome Jason E. Reiss, James E. Hoffman, Barbara Landau U. of Delaware, Johns Hopkins Vision Research, 45 (2005) 3379-3390
3
Why is motion perception an interesting topic here? Atkinson et al (1997, 2003): dorsal breakdown behind WS (based on poor performance on a single motion task: motion coherence) However: Motion perception is not a unitary function!!! Therefore: It is important to look at subfunctions
4
Different classes of motion perception – different neural circuitries: motion coherence: V5/MT (dorsal) biological motion: STS (both ventral and dorsal) form from motion: V5/MT – V4/LO - IT

Conclusions: Not a general motion deficit in WS Cannot be attributed to dorsal dysfunction
