In a differential human fear conditioning paradigm evidence for ABA-renewal was obtained manipulating the lighting in the experimental room. During acquisition in either a dark or illuminated room, one neutral slide was sometimes paired with a loud aversive noise whereas another slide was not. Subsequently, extinction took place in the opposite lighting context. When afterwards the participants were tested again in the original acquisition context, measurements revealed a recovery of the conditioned electrodermal response and an increase in the retrospective verbal US-expectancy ratings. No response recovery was obtained in an AAA-group that received acquisition, extinction and test trials in one and the same context. Several theoretical explanations for this type of return of fear as well as implications for clinical practice are discussed.

Exposure therapy has been shown to be useful for the treatment of anxiety disorders. However, there are individual differences in the extent to which this intervention is effective in reducing symptoms, and a substantial number of patients may experience a return of fear (ROF). The factors associated with successful therapy outcomes are an important topic of investigation as these factors might influence the nature of the interventions as well as enhance our understanding of the process associated with the disorder and its treatment.

Background: Ostomy education and support is instrumental in surgical recovery and adaptation. We aimed to evaluate 1) challenges faced by fecal ostomy patients with colorectal cancer and 2) resources necessary for recovery.
Methods: We recruited patients 21-90 days after scheduled fecal ostomy surgery for locally advanced or metastatic colorectal cancer from a single, tertiary academic center.

Purpose: To investigate return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR), differences based on sex and concomitant meniscal repair, and identify reasons why patients do not RTS.
Methods: Overall, 232 patients undergoing ACLR, with or without concomitant meniscal repair, that were actively participating in pivoting sports at the time of injury, were prospectively recruited. At 2 years, return to preinjury pivoting sport was investigated and, if they had returned, whether they felt their performance was at (or better) or below preinjury status.

Daily life for humans and other animals requires switching between periods of threat- and reward-oriented behavior. We investigated neural activity associated with spontaneous switching, in a naturalistic task, between foraging for rewards and seeking information about potential threats with 7T fMRI in healthy humans. Switching was driven by estimates of likelihood of threat and reward.
