PsychSim 5: MY HEAD IS SPINNING
Section: PSYC 101 – D22 LUO
This activity provides some background information about thinking with verbal concepts versus thinking with mental images.
• What was your train of thought as you navigated the picture of the candle?
Initially seeing the candle I was not aware of what needed to be done until the mouse was moved and I saw the match. I then preceded to drag the mouse to the candle, placed the match on top of the candle and lit the flame. The two images, the cande and the match, created a likely outcome.
Cooper & Shepard’s Results
• In the Cooper & Shepard experiment (1973), participants were asked to decide whether a stimulus (a letter) was normal (simply rotated in the picture plane) or backwards (flipped to its mirror image before the rotation). Reaction times were graphed and increased as the letters were rotated away from 0 degrees. Interestingly, reaction time decreased after 180 degrees. Can you explain why this might occur?
Reaction time increased as the the letters were rotated away from zero because there is a greater angle the closer you get to 180 degrees, taking longer to mentally roate the images .The decresed reaction time occurs because an object rotated beyond 180 can be flipped the other direction, taking less time to mentally rotate it. Rotating the images mentally takes more time per degree of rotation.
Mental Rotation Experiment
• After completing the Mental Rotation experiment and viewing your data, how would you describe the pattern of your results? Do you think that your results fit the pattern of results from the Shepard experiments?
I do believe my results fit Shepard’s experiment. It took me longer to contemplate the images when they reached 180 degress compared to zero degrees. The backward images had an increased response...
