 The weak central coherence theory attempts to explain how some people diagnosed with autism can show remarkable ability in subjects like mathematics and engineering, yet have trouble with language skills and tend to live in an isolated social world.The theory is among the more prominent conceptual models that try to explain the abnormalities of autistic individuals on tasks involving local and global cognitive processes.Uta Frith, of University College London, first advanced the weak central coherence theory in the late 1980s.
