Journal of the Experimental Analysis of Behavior
|January 1, 1975
Summary
Maintaining stimulus control in animal studies is challenging. New methods improved rat auditory threshold accuracy by adjusting stimulus intensity and reinforcement rates.
Area of Science:
- Behavioral neuroscience
- Auditory psychophysics
Background:
- Maintaining stimulus control is crucial for reliable animal psychophysical studies.
- The tracking method often suffers from wandering thresholds and false responses.
Purpose of the Study:
- To develop and evaluate procedures for improving stimulus control in rat auditory psychophysical studies.
- To obtain reliable auditory intensity thresholds using an improved tracking method.
Main Methods:
- Rats were trained to lick for auditory stimuli, with lever responses reinforced by food.
- Two procedures were implemented: increasing stimulus intensity after incorrect responses and maintaining reinforcement rates.
Main Results:
- The implemented procedures significantly improved and maintained stimulus control.
- Reliable auditory intensity thresholds were successfully obtained in the rats.
Conclusions:
- The modified tracking method enhances stimulus control in animal psychophysical research.
- These findings offer a more robust approach for auditory threshold determination in rodents.
