Summary
Pigeons anticipate and perseverate during reversal learning tasks, even when timing cues are removed. Humans, however, adapt by using a win-stay/lose-shift strategy when reversal points vary.
Area of Science:
- Cognitive Psychology
- Animal Behavior
Background:
- Reversal learning involves adapting to changes in stimulus-reward contingencies.
- Previous studies suggest time can act as a cue in discrimination tasks.
Purpose of the Study:
- To investigate if pigeons and humans use temporal cues in reversal learning.
- To examine behavioral strategies in response to predictable versus unpredictable reversals.
Main Methods:
- Pigeons and humans performed a two-choice simultaneous discrimination task with reversals.
- Reversal points were either fixed or variable within sessions.
- Error types (anticipatory and perseverative) were analyzed.
Main Results:
- Pigeons showed anticipatory and perseverative errors, suggesting reliance on temporal cues.
- Humans also anticipated reversals with fixed timing but lacked perseverative errors.
- When reversal timing varied, humans employed a win-stay/lose-shift strategy, minimizing errors.
Conclusions:
- Pigeons appear to use temporal cues in reversal learning, exhibiting anticipatory and perseverative errors.
- Humans demonstrate strategic flexibility, adapting to variable reversal schedules by employing a win-stay/lose-shift approach.

01:08Timing and Consequences on Behavior
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...

01:05Instinctive Drift
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
01:24Generalization, Discrimination, and Extinction
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

01:12Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
01:14Avoidance Learning and Learned Helplessness
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
