Abstract Fear conditioning is an established model for investigating posttraumatic stress disorder (PTSD). However, symptom triggers may vaguely resemble the initial traumatic event, differing on a variety of sensory and affective dimensions. We extended fear-conditioning to assess generalization conditioned fear processing neurocircuitry in PTSD. Military veterans ( n =67) consisting PTSD =32) trauma-exposed comparison =35) groups underwent functional magnetic resonance imaging during low...

Significance Traditional laboratory-based fear-conditioning approaches are often limited in their generalizability to real-world encounters where threats dynamic and embedded contextually rich environments. Moreover, while spatial distance a threat organizes defensive responses, our understanding of the neurobehavioral mechanisms relating proximity fear learning is lacking. To address these limitations, we developed three-dimensional (3D) virtual reality simulation that provides more...
There are concerns regarding what young people exposed to on TikTok due trending content promoting e-cigarette use through humour, marketing and lifestyle acceptability.

Randomized controlled trials (RCTs) are the gold standard for making causal inferences, but RCTs often not feasible in addiction research ethical and logistic reasons. Observational data from real-world settings have been increasingly used to guide clinical decisions public health policies. This paper introduces potential outcomes framework inference summarizes well-established analysis methods observational data, including matching, inverse probability treatment weighting, instrumental...
