Document Summary

In general, antisaccades are used to assess any clinical deficit that is thought to revolve around a deficit in inhibitory dysfunction (the inability to inhibit a wanted response: sz is a disorder that makes it hard to: Tell the difference between what is real and not real. It is a very long and sophisticated pathway that lengthens the rt: those with sz have poor inhibitory control, therefore, they make greater directional antisaccadic errors, the(cid:455) (cid:272)a(cid:374)(cid:859)t suppress the auto(cid:373)ati(cid:272) a(cid:272)ti(cid:448)it(cid:455) of perfor(cid:373)i(cid:374)g a prosa(cid:272)(cid:272)ade.
