Inom ramen för den här forskningen studerar jag vår förmåga att lära oss genom att observera andra människors beteenden genom s.k. social inlärning och hur sådan inlärning kan utnyttjas för att bättre förstå hur vi utvecklar rädslor och hur vi kan förebygga och revidera redan inlärda rädslor. Min forskning utgår från etablerade inlärningsmodeller och kombinerar beteendemått, psykofysiologiska metoder och hjärnavbildning.

Forskningsprojekt 2017-2018

Ongoing behavior / psychophysiological and/or brain imaging projects focused on:

  1. The role of fear memory reconsolidation in diminishing fear
  2. The role of oxytocin in social fear and safety learning
  3. Social group biases in the transmission of fear and safety
  4. Developing dyadic social fear and safety learning models.
