Boris Is Trying to Use Classical Conditioning to Teach His

Boris is trying to use classical conditioning to teach his goldfish to come to the top of the tank to eat whenever he turns on the aquarium light. He drops food into the tank and then turns on the light. After several such trials, the fish show no more inclination to come to the top of the tank when the light is turned on than they did on the first trial. What would you suggest that Boris do to improve his training technique?

A) He should turn on the light before he drops the food into the tank.
B) He should intermittently turn the light on and off during feeding time.
C) He should drop something other than food into the tank to alert the fish.
D) He should provide more food than usual during the trials.
