In this protocol we describe a method of operant learning using sensory stimuli as a reinforcer in the mouse. It requires no prior training or food restriction, and it allows the study of motivated behavior without the use of a pharmacological or natural reinforcer such as food.

This protocol describes how to build a small and versatile video camera, and how to use videos obtained from it to train a neural network to track the position of an animal inside operant conditioning chambers. This is a valuable complement to standard analyses of data logs obtained from operant conditioning tests.

The ability to assess executive functions such as behavioral flexibility in rats is useful for investigating the neurobiology of cognition in both intact animals and disease models. Here we describe automated tasks for assessing strategy shifting and reversal learning, which are particularly sensitive to disruptions in prefrontal cortical networks.

This article describes a new protocol for the quantitative measurement of social motivation in mice using operant conditioning for a social reward. The protocol is useful for the measurement of social motivation in mouse models of autism and other disorders of social behavior.
FAQs
The contingency specifies which action produces the programmed consequence and under what condition. This link lets researchers distinguish behavior that changes because a defined response was reinforced from behavior occurring without that relationship. By holding the contingency steady or changing it systematically, investigators can examine how learning develops and how response rates change.
Shaping builds a target behavior gradually by arranging reinforcement as the animal moves toward the specified response. This approach is useful when the complete action does not initially occur reliably, because the training sequence can support progressive improvement rather than requiring immediate mastery. The chamber then records whether the response becomes established across trials or sessions.
Changing programmed reinforcement schedules gives researchers a way to compare learning under different consequence arrangements. Reinforcement therefore becomes more than a simple reward delivery; its programmed pattern can be varied while responses are measured consistently. These comparisons help investigators evaluate how schedule conditions relate to acquisition and response rates.
The recorded responses can support separate analyses of acquisition, extinction, discrimination, and motivation. Acquisition concerns the development of responding, whereas extinction and discrimination examine how performance changes under altered conditions. Together, these measures provide a broader account of learning than a single endpoint, such as whether an animal eventually performs the trained action.
A typical setup requires a controlled chamber, a response device such as a lever or nose-poke port, a programmed consequence such as food, and a recording system. The apparatus must detect the defined response and apply the contingency consistently. These components connect the animal’s behavior with measurable training data and controlled reinforcement.
Researchers standardize the chamber environment and the programmed response–consequence relationship so that experimental variables can be changed deliberately. Consistent recording helps separate changes caused by the planned manipulation from differences in measurement or setup. This control makes the technique suitable for comparing learning across reinforcement conditions, environmental variables, or experimental groups.
The method is useful when investigators need precise behavioral measurements while studying learning principles, behavioral pharmacology, or environmental effects on behavior. It can reveal changes in response rate and other learning outcomes under defined conditions. Because the procedure combines controlled contingencies with recorded performance, it supports systematic comparisons across experiments.
