Cells show numbers for each item except SPAN Composite and Age, which show mean (SD). SPAN data for four participants (one HCC and three LCC) were lost at a later date due to technical difficulties. Polypharmacy was defined as taking more than one psychotropic medication. One SZ subject was taking lithium in addition to antipsychotics and one SZ subject was taking Adderal. HCC = high cognitive control group; LCC = low cognitive control group; SZ = schizophrenia group.
