Study- Yantis 1993 This study was done by Steven Yantis and it is related to Ulric Neisser’s visual search study. This experiment compared different kinds of singletons in a display (i.e. one red letter in a set of green letters) to determine whether any of them capture attention differently. The research found that onset singletons (items that appear suddenly) capture attention, but that other types of singleton (color or brightness) do not. This agree with my hypothesis which is that the average mean time is higher when the background is similar to item in front. Note that this is only the case if participants have been informed that the singletons that will appear are irrelevant to the task they are performing.

    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.
