Response-specificity or response-generality of inhibition in an operant feature-negative discrimination: Influence of the amount of inhibition training and attention to the response.

The suppression of behavior that occurs in instrumental extinction is strikingly specific to the response. In contrast, Steinfeld and Bouton (2022) recently reported that inhibition developing in an operant feature-negative (FN) discrimination is not specific to the response. In two experiments, we tested two potential explanations of why inhibition in FN learning is relatively response-general.

Physician Associate/Assistant Program Medical Directors Are Important Advocates for the Physician Associate/Assistant Profession: Results From a National Pilot Study.

Introduction: This pilot study aimed to evaluate whether and how physician associate/assistant (PA) program medical directors play a role in advocating on behalf of PAs and what factors correlate with this.

Methods: The study used a mixed-methods grounded theory approach and was deemed institutional review board exempt. After literature review, a survey was developed and piloted by study personnel and faculty to affirm validity.

Cylindroma of the Breast: A Rare Differential for Breast Cancer on Core Biopsies, Case Report and Review of Literature.

Breast cancers of either ductal or lobular pathology make up the vast majority of breast malignancies. Other cancers occur rarely in the breast. Benign pathology can at times mimic breast cancers on imaging and initial needle biopsies.

An analysis of reinstatement after extinction of a conditioned taste aversion.

Taste aversion learning has sometimes been considered a specialized form of learning. In several other conditioning preparations, after a conditioned stimulus (CS) is conditioned and extinguished, reexposure to the unconditioned stimulus (US) by itself can reinstate the extinguished conditioned response. Reinstatement has been widely studied in fear and appetitive Pavlovian conditioning, as well as operant conditioning, but its status in taste aversion learning is more controversial.
