A NEUROBIOLOGICAL ALTERNATIVE TO THE PERCEPTUAL REINFORCEMENT HYPOTHESIS OF STEREOTYPED BEHAVIOR: A COMMENTARY ON “SELF-STIMULATORY BEHAVIOR AND PERCEPTUAL REINFORCEMENT”

Effects of alternative responses on behavior exposed to noncontingent reinforcement.

Noncontingent reinforcement (NCR) may decrease the frequency of behavior by either inducing satiation or terminating the response-reinforcer contingency (extinction). Another possibility is that the target behavior is replaced by other behaviors maintained by preexisting contingencies. We conducted 2 experiments in which we allowed access to a target response and several alternatives. In Experi...

Reinforcement Learning with Perceptual Aliasing :

The Perceptual Distinctions Approach Lonnie Chrisman School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213 [email protected] Abstract It is known that Perceptual Aliasing may signi cantly diminish the e ectiveness of reinforcement learning algorithms [Whitehead and Ballard, 1991]. Perceptual aliasing occurs when multiple situations that are indistinguishable from immediat...

A component analysis of "stereotypy as reinforcement" for alternative behavior.

Results from several studies have suggested that the opportunity to engage in stereotypic behavior may function as reinforcement for alternative, more socially desirable behaviors. However, the procedural components of this intervention include several distinct operations whose effects have not been analyzed separately. While measuring the occurrence of stereotypy and an alternative behavior (m...

Differential Reinforcement of Alternative Behavior in a Child With Autism

Self-Organizing Perceptual and Temporal Abstraction for Robot Reinforcement Learning

A major current challenge in reinforcement learning research is to extend methods that work well on discrete, short-range, low-dimensional problems to continuous, highdiameter, high-dimensional problems, such as robot navigation using high-resolution sensors. We present a method whereby an robot in a continuous world can, with little prior knowledge of its sensorimotor system, environment, and ...
