请各位帮我解答这个题目~ 谢谢!!
In a research study, participants had to decide whether
rotated letters were normal or mirror images of themselves.
An analysis of participant reaction times indicated that
A) the task proved impossible for most participants to perform
B) the farther a letter was from normal, the faster it was mentally
rotated by the participant
C) decision times were proportional to the degree to which each
letter had to be mentally rotated
D) there was little relationship between the degree to which each
letter had to be mentally rotated and reaction times
我找了很久，还是不知道正确答案到底是哪一个
我觉得答案是Ｃ
这是成大９８年转学考的考题
顺便想请问有没有人有成大心理学的解答？？
谢谢
