Abstract

Equivalent of stimuli's model for the analysis of anxiety disorder: the effects of experimental history and stimulus characteristics in anxious and non-anxious subjects. Eight subjects, four anxious and four non-anxious (the free choice group) were exposed to a conditional relation task, with threatening and non-threatening stimuli. The subjects could form homogeneous relations (only threatening stimuli or only non-threatening ones) and mixed relations (threatening and no threatening stimuli). Eight other subjects, four anxious and four non-anxious (the forced choice group) could only form mixed relations. After a training of mixed relations, the non-anxious in the free choice group formed as many mixed classes as homogeneous ones while the anxious, only formed homogeneous relations. In the forced choice group neither neither a nxious nor non-anxious subjects showed any preference to form either one of these types of classes. The data suggest that the difficulty which anxious subjects have in forming mixed relations is due to pre-existing threatening and non-threatening stimulus-classes. Furthermore, a preceding context of forced mixed choices can interfere in the patterns of emergent relations.

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.
