The present study aimed to investigate the effects of exposure to a protocol of chronic mild stress (CMS) on the maintenance of a previously learned operant discrimination. Four experimentally naive male Wistar rats were subjected to 10 sessions of discriminative training (multiple VI 15 s / Extinction), 28 sessions of discriminative training concomitantly with exposure to CMS, and five sessions of discriminative training after the exposure to stress protocol. As a result, the discriminative indexes decreased, and the frequency of responses increased in the first two weeks of exposure to the stress protocol. In the last two weeks of exposure to the stress protocol, these effects reversed for most subjects. The frequency of reinforcement was maintained relatively constant throughout the study. When the CMS was interrupted, the discriminative indexes were superior to that observed in the baseline for most subjects. The results suggest that the first weeks of exposure to stress protocol can impair the discriminative control previously established.

Pre-Print, Accepted Manuscript, and Final Published Version Archiving, Sharing and Re-Use Policy
The authors’ contribution to RBTCC has three versions, which are defined below and can be archived, shared, and re-used under the following conditions:
1. A pre-print (or original submission) is the author’s version of the article before peer-review has taken place. Prior to acceptance for publication, author(s) retain the right to make a Pre-Print of their article available: on their own personal, self-maintained website; or on a legally compliant pre-print server (e.g., PsyArXiv, arXiv). Once the article has been published, the author(s) should update their acknowledgement and provide a link to the definitive version on RBTCC’s website, adding a text such as: “This is a pre-print of an article published in the Brazilian Journal of Behavioral and Cognitive Therapy. The final authenticated version is available online at: https://doi.org/[insert DOI]”. RBTCC encourages posting of preprints of manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration from RBTCC. Authors should disclose details of preprint posting - including DOI and licensing terms - upon submission of the manuscript or at any other point during consideration at RBTCC publication process.
2. An accepted manuscript is the version accepted for publication in RBTCC following peer review but prior to copyediting and typesetting that can be made available under the following conditions:
(i) on their own personal, self-maintained website immediately on acceptance,
(ii) for public release, 12 months after first publication (i.e., "Embargo Period"), on any of the following: their employer’s internal website; their institutional and/or funder repositories. Accepted manuscripts may also be deposited in such repositories immediately on acceptance, provided that they are not made publicly available until after the Embargo Period.
An acknowledgement in the following form should be included with a link to the published version on the publisher’s website: “This is a post-peer-review, pre-copyedit version of an article published in the Brazilian Journal of Behavioral and Cognitive Therapy. The final authenticated version is available online at: http://dx.doi.org/[insert DOI]”.
3. The final published (PDF) version is the copy-edited and typeset RBTCC’s PDF, the same version published on the journal’s website. It can be archived in institutional or funder repositories and can be made publicly accessible immediately.
Any re-use terms for users of websites and repositories (where your pre-print or accepted manuscript are posted) are restricted to non-commercial and no derivative uses.
The authors may not republish or translate any version of their contribution in another journal without prior permission from RBTCC’s Editor-in-Chief.
