What did research from Taylor&Kinderman show?
Students with a poor TOM score made more paranoid style Ext. Personal attributions compared to those that did well on the TOM Q. Supports the link between TOM+attributions in PD

What did research from Sprong show?
TOM scores of SZ pps were much worse than healthy pps. The 'disorganised' SZ group had much worse TOM scores, and the poor TOM was present before the disorder began. Strong evidence for the case of SZ -> a poor TOM!
