Time reallocation in a multiresponse environment: Effects of restricting response classes
Journal of the Experimental Analysis of Behavior
|May 1, 1984
Summary
Behavioral studies on rats found that restricting access to certain responses, like darkness or noise escape, did not follow predictive rules for how behavior redistributes. Empirical assessment is crucial for understanding restriction effects.
Area of Science:
- Behavioral science
- Animal behavior studies
- Operant conditioning
Background:
- Understanding how animals redistribute their behavior after experiencing response restriction is key in operant conditioning.
- Previous models proposed rules for predicting behavioral changes, but empirical validation is often lacking.
Purpose of the Study:
- To test four predictive rules regarding behavioral redistribution following response restriction in rats.
- To investigate the effects of restricting low- and high-probability responses on behavior.
Main Methods:
- Four adult male rats were exposed to an apparatus with six distinct location-defined responses for three hours daily.
- An A-B-A-C-A design was used, manipulating the restriction of darkness (low-probability) and noise escape (high-probability) responses.
- Behavioral redistribution was measured as the percentage of session time spent in each compartment.
Main Results:
- None of the four tested predictive rules (constant-ratio, equal time redistribution, most probable alternative, sequential-dependency) were supported by the data.
- The study found that the actual redistribution of behavior did not align with theoretical predictions.
Conclusions:
- The findings suggest that current predictive rules for behavioral redistribution after response restriction are inadequate.
- Empirical assessment of restriction effects is essential for accurate reinforcement studies, especially those involving extended response durations.

02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
01:13Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

02:01Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
01:25Dose-Response Relationship: Selectivity and Specificity
Drugs exert their therapeutic effects by interacting with receptors, enzymes, or ion channels that are present throughout the human body. The strength and duration of the interaction between a drug and its target receptor are characterized by the selectivity and specificity of the drug. Selectivity refers to a drug's strong preference for its intended target over other targets. For instance, isoprenaline, a non-selective β-adrenergic agonist, interacts with both β1- and β2-adrenergic receptors...
01:21Dose Response Curve: Conventional Versus Nonmonotonic
The correlation between a drug's dosage and its impact on a biological system is a cornerstone of pharmacology and toxicology. Conventional dose–response curves, which include graded and quantal relationships, are key to this understanding. Graded dose–response curves depict the spectrum of a biological reaction to different doses within an individual, indicating that as the drug dosage increases, so does the intensity of the response. On the other hand, quantal dose–response relationships...
01:09Censoring Survival Data
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different reasons...
