Syllabus: How Does Experience Change Behavior?
Use the behavioral characteristics to turn an everyday observation into a discriminating comparison. Keep habituation and sensitization distinct.
Why you’re reading it. Introduce a form of learning that does not require pairing two different events, while ruling out simpler explanations for reduced responding.
A question to consider. The volunteer stops turning toward a repeated background sound. How could you distinguish habituation from fatigue or reduced hearing?
Why this reading
A diminishing response is easy to observe and easy to misinterpret. This short synthesis explains the comparisons that help identify habituation, introducing learning without requiring an association between two distinct events.
Before you read
Habituation is a decrease in responding after repeated stimulation that is distinguishable from sensory adaptation or motor fatigue. Sensitization is increased responsiveness and can occur alongside habituation. A stimulus is an event that an organism can detect; a response is the measured reaction.
Read for
- Compare the original and revised characteristics and ask what each revision makes easier to observe or distinguish.
- Track stimulus specificity, recovery after a pause, and dishabituation: recovery of the response to the original stimulus following a different stimulus.
- Distinguish a behavioral pattern from a claim about one universal neural mechanism.
Consider afterwards
- A person reacts less to a repeated background sound. Which comparison would help distinguish habituation from an inability to hear or respond, and what would recovery after a pause add?
Editorial context
The article synthesizes work across species and procedures; it is not a new controlled experiment. Its characteristics guide investigation with stated qualifications. Sensitization is acknowledged but not reviewed in comparable depth. The 2008 online date and the 2009 journal issue refer to the same work; the citation uses the issue year.
