Dr. haviland is looking at mental rotation data but he forgot to label his chart. the data shows reaction times for 700 ms, 1400 ms and 1200 ms. what are the most likely corresponding degrees of rotation that will match his data? 90 degrees, 180 degrees, 120 degrees 90 degrees, 120 degrees, 180 degrees 180 degrees, 90 degrees, 120 degrees 120 degrees, 180 degrees, 90 degrees

An important part of research into mental rotations (namely the field of neurology that studies how our brains perceive figures in 3-D or 2-D and how they decide whether 2 object have the same shape) in the early days regarded the speed of recognition; it was found out that there is an increasing function relating angle of rotation and speed of the observer. This means that the more the object was rotated from its initial position, the more time was needed to decide that it is the same shape. Hence, correct is the first choice, since the inequalities in time have to be satisfied by the angles (in that order).
