In addition, we showed that perinatal FLX exposure impairs the display of prosocial behavior in female rats. Moreover, we found no signs of prosocial behavior in CTR- and FLX-males after natural aggressive encounters. After white-noise exposure the effects in third party prosocial behavior of CTR-females ceased to exist. We conclude that female rats are able to show prosocial behavior, possibly in the form of consolation behavior. In addition, the negative effects of perinatal fluoxetine exposure on prosocial behavior could provide additional evidence that SSRI treatment during pregnancy could contribute to the risk for social impairments in the offspring. In one human predictive learning experiment, we demonstrated that an individual's propensity for response recovery following discrimination reversal learning is stable over time. Participants received four sessions of training with the first three sessions being separated by one week each, while the last session was conducted after a delay of four weeks. During each session, participants initially received discrimination training (E+, F-) in one context, followed by discrimination reversal training (E-, F+) in another context. Sessions each completed with a test, in which the stimuli were presented in the context of initial acquisition. Each test revealed response recovery according to the initially acquired stimulus-outcome contingencies. Furthermore, the strength of response recovery was correlated across sessions that were separated by one week (Sessions 1 and 2), and across sessions separated by four weeks (Sessions 3 and 4). Overall, intra-individual test behavior was stable in 87 % of participants across two sessions, and in 79 % of participants across four sessions. Our resul
