How are conditioned fear and avoidance responding connected?
A. They are always correlated throughout training; subjects' levels of fear get higher as they become more conditioned to the avoidance behaviors.
B. They are correlated throughout most of the training process; subjects' levels of fear get higher as conditioning goes on until the participant reaches a critical level of anxiety, after which they level off.
C. They are correlated intermittently; subjects' fear levels fluctuate over time, so sometimes they are afraid when the warning signal occurs, and sometimes they are not.
D. They are correlated only early in training; after being conditioned to exhibit avoidance behaviors, avoidance responding may persist without any fear being exhibited when the warning signal occurs.
