[Transsexuals' life satisfaction after gender transformation operations].

Background: More and more frequently, the registration of life satisfaction is being used to evaluate different medical treatments. So far, there have been only few such surveys on transsexuals (TS). Therefore, the aim of this study was to evaluate the general and the health-related life satisfaction of transsexuals after gender transformation operations.

[Avoidance learning in a social situation- extinction resistance and defense reaction under stress. A pilot study].

Two successive experiments were conducted resulting from observations of the stability (resistance to extinction) of avoidance reactions and the manifestation of such reactions beyond the specific avoidance conditions in which they were acquired: a) 15 subjects were set the task to avoid an aversive acoustic stimulus for a helpless experimental partner. They could achieve this by reacting with contraction of either the forearm or the calf muscles in a difficult discrimination task. The stability of these avoidance reactions was assessed on different levels of forced extinction.
