Behavioral flexibility, the ability to change behavior in accordance with the changing environment, was studied in pigeons using a series of reversal learning paradigms. All experiments involved a series of 5-trial sequences and I was interested in whether pigeons are sensitive to the reversal by switching to the other alternative after a single error. In Experiments 1 and 2, the overall probability of the two stimuli was equated over sequences, but the probability correct of the two stimuli changed across trials. In both experiments, subjects showed no sensitivity to the differences in sequence type. Instead they used the overall average …

Effects Of A Short-Term Mindfulness Intervention On Depression And Immune Function, Erin C. Walsh
Theses and Dissertations--Psychology
Pro-inflammatory cytokines have been implicated in the pathophysiology and maintenance of depression. This study investigated the effects of a short mindfulness intervention on pro-inflammatory correlates of depression (IL-6 and TNF-α) and selfreported psychological health. Sixty-four college females were assigned to a four-week mindfulness training group or a contact-control group. Cytokines and psychological health were assessed at baseline, post-treatment, and 3-month follow-up (mindfulness group only). IL-6 and TNF-α significantly decreased from baseline to post-treatment in the mindfulness group only; these changes were sustained at 3-month follow-up. No between-group differences in psychological health emerged. Although reductions in proinflammatory cytokines in the mindfulness …
