Department of Psychology, Washington University, St Louis, MO 63130, USA
Percept Psychophys 67:219-23. 2005..One possible explanation is that the onset of motion captures attention because it serves as a strong cue to animacy--and the detection of nearby animals can have important consequences for survival... - Executive control of learning and memory in children with bilateral spastic cerebral palsyDesiree A White
