Copy a Scene Task (Unilateral Neglect)

Patients will be asked to copy a scene on a horizontal A4 sheet. The total score is 6 points: 1 for the trees on the right (omission of the left half of a tree = 0.5), 2 for the house (omission of a window, the door or a part of the roof = 0.5; omission of the left half of the house = 1), and 1 for the trees on the left. Scores are considered pathological when superior or equal to 0.5 (Gainotti, DErme, Monteleone, & Silveri, 1986).

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.

@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.

Thanks for commenting!

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

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.

i just learned about this today in cognitive psychology!! this is crazy and so interesting. goes to show just how complex the brain is.

@KocaniCanada

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

@KocaniCanada

thank you!! i'll look into those
