Question 21

Ferret Navigation Study

Researchers wanted to investigate how different reinforcement schedules and consequences influence learning in ferrets.

Ferrets were trained to navigate a sequence of three tube entrances (Left, Right, Middle) in a specific order.

Each ferret was randomly assigned to one of four conditions:

  • Condition 1: A drop of sweet water was delivered every time the ferret performed the correct sequence of choices exactly 5 times in a row.
  • Condition 2: A drop of sweet water was delivered after the ferret performed the correct sequence a variable number of times, averaging 3 sequences (the exact target changed unpredictably after each reward).
  • Condition 3: A drop of sweet water was delivered every 45 seconds, provided the ferret had performed the correct sequence at least once during that time increment.
  • Condition 4: A brief, harmless puff of air was directed at the ferret's snout immediately if they made an incorrect choice in the sequence.

The table below shows the results of the 15-minute experimental trials.

Condition 16248
Condition 210482
Condition 33222
Condition 482

Using research evidence or psychological concepts, explain how operant conditioning theory could support the findings of the ferret navigation study.
