Particularly Broca’s aphasia has been associated with difficulties in processing pseudowords. In aphasia studies, they are often used to measure syllable frequency by having patients attempt to pronounce them.[7] Also, patients with left hemisphere damage (LHD) tend to have significantly greater difficulty writing pseudowords than those with right hemisphere damage.[8] This specific deficit is known as the lexicality effect. It occurs in the presence of perisylvian, rather than extrasylvian, damage in the left hemisphere.[9]
