Optokinetic Observation

Another current study looked into whether optokinetic stimulation, when projected onto a see-through head-mounted display, could help treat neglect subjects in a new form of therapy. In this study, Improvement of hemispatial neglect by a see-through head-mounted display: a preliminary study, fourteen patients with neglect performed the simple task of line bisections on a computer screen. The patients performed this with and without optokinetic stimulation, which was delivered either by the display or on the computer screen. The researchers found that optokinetic stimulation projected onto the display improved neglect, suggesting that the development of a comparable, more transportable device could potentially be a significant aid in the treatment
In the study, Hemispatial neglect in young children with early unilateral brain damage, thirty three infants and toddlers and twenty seven preschool children with “either left or right hemisphere damage of pre or perinatal onset” were studied against thirty six control children, through two object removal preference tasks. The children with the hemisphere damage preferentially removed objects from the “ipsilateral side of their lesion first and the contralateral side last” while the control children showed no partiality. The researchers concluded that neglect may indeed be found in young children after unilateral brain damage, but that there may be a different distribution of attention to space when comparing mature to immature brains (Trauner,
The doctor holds out his arms, placing them wide, so that they are in a normal person’s unobstructed line of vision. He instructs Simon to tell him which finger he sees move or both if they both move. After Simon fails to see the finger on the left side move, the doctor slowly begins to move his hand in. Only when his hand is in the middle of Simon’s vision does Simon see it. He continues to get the fingers correct, but fails to see them move at the same time. The doctor performs another test with Simon, showing him a straight line drawn on a piece of paper. The doctor asks Simon to mark the middle of the line. Simon mark halfway between the halfway point and the right edge of the line. After the paper is moved to the right side of his visual field, he notices that he hadn’t seen the entire line before (S, 2013). It is clear the Simon presents the classic symptoms of neglect. From the personal recollections, the doctor’s assessments, to the evidence of his drawings, Simon tends to ignore the left half of his work. Although it was not explicitly mentioned, I would predict that Simon’s neglect came on after suffering from a stroke given the source of the video. The tests that the doctor performed on Simon shows that his field of vision is limited, cutting out the majority of his left side. However, Simon usually realizes his errors after they are pointed out to him. These realizations are also classic in
