is this right? i mean....limbs, sure, but pictures too?? i highly doubt this. the person can perceive, say, people around him/her with his/her one side, but not the other. however, i'm sure the person can draw those people he/she sees with her 'working' eye just fine. What i'm trying to say is that: this demonstration seems inaccurate, as the person can easily see the picture through one eye, unless the picture is held up right against the person's face.
Dear jaejunie,I would like to point out few details to clear misunderstandings that your comment might cause to other readers. First of all, unilateral neglect is a disorder that has nothing to do with the eye-condition (referring to what you addressed as 'working eye'). That is, neglect patients fail to attend and respond to stimuli presented on the side of space opposite to the brain lesion. However, the eyes are intact.
sorry for the confusion - it's just that from this case that i had read, the person could perceive the people on the right as being in the room, but not the ones on the left until it had been pointed out by others (and still had doubts!) so i thought maybe it has to do with the left eye right eye perception
@jaejunie Spatial neglect can be further divided into peripersonal neglect and extrapersonal neglect. Peripersonal neglect refers to neglect behaviors occurring within reaching space (near space). An example of peripersonal neglect is failure to eat the food on one half of a plate (Plummer et al., 2003).
@jaejunie Extrapersonal neglect refers to neglect behaviors occurring in far space. An example of extrapersonal neglect is inadvertently contacting obstacles such as a doorway when walking (Plummer et al., 2003). Therefore, this demonstration IS ACCURATE. Incomplete drawing or copying with omissions or gross distortions on the contralesional side during Copy-a-scene task is considered indicative of Unilateral Left Neglect.
@skunkfcuk Hi, The example was made to go along with a presentation about possible future direction for treatment of unilateral neglect. Due to ethics it's always hard to find videos of how patients perform during this task, and by closely following previous findings and reports we were able to reproduce what this might look like. Thanks for your comments and questions!
Hi! This is a demonstration of what this drawing might look like if done by a patient. The choice of the lines that were not copied during this video are however based on reported findings in published papers on unilateral neglect. Due to the lack of videos on these tests we tried to reproduce them as accurately as possible based on reported findings. Hope you find it helpful :)
i just learned about this today in cognitive psychology!! this is crazy and so interesting. goes to show just how complex the brain is.

Thanks for commenting!
P.S. I apologize for the cropped comments, it wouldn't let me post such a long text at once!
