question 218

Multiple Choice

Shepard and Metzler tested subjects by showing them a series of pictured geometric shapes. Then they showed them a set of pictures containing the same shapes, rotated into different positions, and shapes they had never seen before. The researchers found that

• A) the more the objects had to be rotated imagery, the longer it took the subjects to decide if the picture matched the original shape
• B) the more objects needed to be manipulated, the more the subjects could not do the experiment, revealing that images have a limited range of motion.
• C) the longer it took to rotate the object imagery, the quicker the subjects correctly dismissed shapes they had not seen before.
• D) None of the subjects were able to correctly identify objects whose picture showed them a position of rotation more than 145 degrees from their original orientation.
