Simulating bout-and-pause patterns with reinforcement learning [article]

Kota Yamada, Atsunori Kanemura
2019 bioRxiv   pre-print
The first mechanism is choice---an agent makes a choice between operant and other behaviors. The second mechanism is cost---a cost is associated with the changeover of behaviors.  ...  Previous studies have investigated how these three components are affected by experimental manipulations. However, it remains unknown what underlying mechanisms cause bout-and-pause patterns.  ...  schedule 509 without affecting the behavior for the other schedule.  ...

Concurrent Schedules of Positive and Negative Reinforcement: Differential-Impact and Differential-Outcomes Hypotheses

Michael A Magoon, Thomas S Critchfield
2008 Journal of The Experimental Analysis of Behavior  
In the present investigation, humans' mouse-click responses were maintained on similarly structured, concurrent schedules of positive (money gain) and negative (avoidance of money loss) reinforcement.  ...  This may represent the first empirical confirmation of a free-operant differential-outcomes effect predicted by contingency-discriminability theories of choice.  ...  An experimenter will record how much you earn at the end of each session. Please do not hesitate to ask the experimenter any questions you may have.  ...

Preference between variable-ratio and fixed-ratio schedules: local and extended relations

D P Field, F Tonneau, W Ahearn, P N Hineline
1996 Journal of The Experimental Analysis of Behavior  
The birds' choices of the variable-ratio schedule tracked the size of the smallest variable-ratio component.  ...  The birds' behavior was qualitatively consistent with Mazur's (1984) hyperbolic model of delayed reinforcement and could be described as approximate maximizing with respect to reinforcement value.  ...  approach is to focus on the individual components of the variable schedule and on how their respective contributions combine at a behavioral level (e.g., Shull & Spear, 1987) .  ...

Interaction Of Reinforcement Schedules, A Behavioral Prosthesis, And Work-related Behavior In Adults With Mental Retardation

Richard R Saunders, Julie E McEntee, Muriel D Saunders, Jennifer McComas
2005 Journal of Applied Behavior Analysis  
Combining the behavioral prosthesis with FR reinforcement (FR+O) increased the proportion of time spent in on-task behavior by all participants under certain FR schedule parameters.  ...  Overall, the results show how organizer and schedule parameters can be adjusted to produce an optimized balance between productivity and reinforcement while undesirable behavior is minimized.  ...  Not yet shown is how the various conditions affected the distribution of off-task and aberrant behavior within work sequences and PRPs.  ...

Chronic Exposure to Methamphetamine Disrupts Reinforcement-Based Decision Making in Rats

Stephanie M Groman, Katherine M Rich, Nathaniel J Smith, Daeyeol Lee, Jane R Taylor
2017 Neuropsychopharmacology  
Computational analyses of parameters that track choice and outcome behavior indicated that exposure to MA significantly impaired the ability of rats to use negative outcomes effectively.  ...  We suggest that the disruption in utilization of negative outcomes to adaptively guide dynamic decision making is a new behavioral mechanism by which MA rigidly biases choice behavior.  ...  ACKNOWLEDGMENTS This study was supported by public health service grants DA041480 and DA043443, NARSAD, the Charles B.G. Murphy Fund, and the State of CT Department of Mental Health Services.  ...

Effects of problem difficulty and reinforcer quality on time allocated to concurrent arithmetic problems

F C Mace, N A Neef, D Shade, B C Mauro
1996 Journal of Applied Behavior Analysis  
Unlike problem difficulty, the pairing of the lesser quality reinforcer (program money) with the richer schedule reduced the time allocated to that alternative.  ...  DESCRIPTORS: problem difficulty, reinforcer quality, matching law, concurrent schedules The matching law (Herrnstein, 1961 (Herrnstein, , 1970 states that the relative rate of responding on concurrently  ...  Experimenters can then vary the response requirements for each alternative and determine how relative differences in problem difficulty affect the relative allocation of behavior across the alternatives  ...

Choice, Matching, and Human Behavior: A Review of the Literature

W. David Pierce, W. Frank Epling
1983 The Behavior Analyst  
This review concerns human performance on concurrent schedules of reinforcement. Studies indicate that humans match relative behavior to relative rate of reinforcement.  ...  While problems with instructional control are raised, the overall findings support the matching law as a principle of human choice. Reprints may be obtained from  ...  Choice and preference are pervasive aspects of human behavior. Concurrent schedules of reinforcement (Herrnstein, 1961) provide a procedure for the experimental analysis of choice behavior.  ...
