Document Summary
Posner cueing task: measures endogenous attention, because the orienting of attention to the cue is driven by the su(cid:271)je(cid:272)t(cid:859)s goals, rather tha(cid:374) (cid:373)erel(cid:455) its ph(cid:455)si(cid:272)al features and the salience of these features. Neglect patients given the posner cueing task: valid cues resulted in faster rts, regardless of which hemispace the target stimulus appeared. Defined by the symptom of patients behaving as though parts of objects, and/or the world around them, do not exist and they are largely unaware of this deficit. Typically associated with strokes or brain injuries to the right parietal and frontal cortices. The specific location of cortical damage that causes visual neglect is a matter of fierce debate stroke may cause lesions across many different regions, only some of which contribute to neglect. Studies have highlighted than lesions of the right inferior parietal lobe centred on the angular gyrus are most likely to cause neglect.
