Compared to the sham taVNS, taVNS improved SWM performance in older patients with schizophrenia. Furthermore, the SWM performance after a single session of taVNS showed fewer errors in the taVNS group, whereas no such improvement was observed in the sham taVNS group. Unlike in SWM, there were no significant between\u2010group differences in RTI, PAL or MTT after either a single stimulation or a session of 10 stimulations.\n                    <\/jats:p>\n
