Behavioral Drift
The gradual deterioration or change in a learned behavior over time, typically away from the originally trained response pattern.
Full Definition
Behavioral drift refers to the progressive degradation of behavioral performance over time, where learned behaviors gradually deviate from their original form or frequency. This phenomenon commonly occurs when reinforcement contingencies become inconsistent or when environmental factors change. In behavioral medicine, drift is a significant concern for maintaining treatment gains, as patients may gradually return to previous unhealthy patterns. Understanding and preventing behavioral drift is crucial for developing effective maintenance strategies and ensuring long-term treatment success.
Usage
Usage note: Often confused with relapse, but drift is typically more gradual and less complete.
