Why Does Mental Rotation Take Longer for More Rotated Objects?

💡 The Answer

• Shepard and Metzler's classic experiment revealed a linear relationship between rotation angle and response time.
• Our brains simulate physical rotation mentally, requiring more time for greater angular disparities.
• This effect demonstrates that mental imagery operates analogously to actual visual perception.
• The parietal cortex is heavily involved in rotating objects in the mind's eye.
