Roshini Ninan Cognitive Psychology Seminar Two: Thur. February 6, 2014 Rossetti, Y., et al. (1998). Prism adaptation to a rightward optical deviation rehabilitates left hemispatial neglect. Nature, 395, 166-169. 1. Define unilateral visual spatial neglect in your own words. How do we know that neglect is an attention problem and not just a loss of visual ability in the left visual field (i.e., a “visual field cut”)? - Unilateral visual spatial neglect occurs when one hemisphere of the brain is damaged and the person has trouble with doing activities and awareness and vision occurring on the opposite side of their body. We know that neglect is an attention problem and not a loss of visual ability in the left visual field because a person with a visual field cut would not be able to see the object, on the other hand neglect just doesn’t bring an object into the person’s conscious field of vision so they cannot perceive it. 2. Imagine that you are working with a person with left spatial neglect. He failed to locate or use objects on the left and he could not read because he only read the words from the midline to the right side of the page. When maneuvering his wheel chair, he consistently bumped people and objects on the left. What are some treatments that you would devise to draw his attention to the left? He would you know if the treatment was working? - Some treatment methods I would use would be encouraging him to move his head to the left side to see objects, if he could not do this alone, I would assist in moving his head. I would also encourage his family members to touch that side of his body to make him more aware of that side, as well as encouraging him to use the left hand in other daily activities.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
