2019, Psychiatry ResearchCitation Excerpt :Increased interference in the card Stroop task has also been demonstrated in schizophrenia, reflecting a reduced ability to suppress irrelevant responses and selectively attend when salient distracters are present. Thus our current findings are broadly consistent with an existing tradition in the schizophrenia research literature of deficits in attentional tasks (Gooding et al., 2006), as well as studies reporting correlations between reality distortion and attentional impairments, usually in chronic populations (Berman et al., 1997; Ventura et al., 2010). Along with evidence from human experimental psychology, our data provide increased support for neuropsychological theories of delusions (Blackwood et al., 2001) hypothesising that subtle deficits in attentional or information processing capability contribute to the formation and maintenance of delusions and hallucinations.
