Rotation of the letter R :: Essays Papers

Rotation of the letter RPsychologists have been interested in the processes that go on in the intelligence for centuries. However, a new method for assessing the various processes emerged in the 1970s. Several researchers predicted that kind imagery was treated by the brain similarly to actions dischargeed on material objects. Thus, performance in tasks involving inspection, rotation, and comparison of mental images according to size should be similar to results obtained using factual objects. Kosslyn, Ball, and Reiser (1978) asked participants to scan a mental comprise after studying a map of an island with several(prenominal) landmarks. They predicted that the further the keep between the landmarks, the lifelong it would take participants to scan from one to the next, whether using the actual map or a mental image created by intensive study. Their hypothesis was supported by their results. The closer positions took less time to subside on the participant mental maps than t he more distant places.In 1973, Cooper and Shepard asked participants to perform a mental rotation task. They gave the participants an image, and asked them to rotate it mentally by a certain angle, and then match the rotate image with one of several choices. Their prediction was that the greater the angle of rotation, the longer the task would take. This was because it would take longer to physically rotate a figure more degrees than fewer degrees. The picture supported this hypothesis The closer the angle is to 180 degrees, the longer the reaction time. Angles greater than 180 degrees do not take longer because the national will rotate it in the other direction. So the angle outgo from 180 degrees, called the angle of disparity, is directly related to the reaction time. The experiment through with(p) by the class involves looking at the letter R on a computer screen, and determining whether it is forward or reverse. The R is rotated at varying degrees, and participants must m entally rotate the R in order to determine whether it is forward or reversed. A forward R is the letter R in its usual orientation. The reversed R is backward from its usual position.There were several predictions made by the class onward the experiment was run. The highest reaction time was predicted to be at the 180 degrees condition, with the last-place reaction time at 0 degrees, increasing in both directions toward 180 degrees. Also, the average reversed-figure reaction time was expected to be high than the average normal time.
