| Research Abstract |
The aim of this study was to elucidate the relationship between salivary cortisol diurnal rhythm and emotional memory consolidation in healthy subjects. Salivary cortisol levels were measured at four time points(8:00, 11:00, 15:00, 20:00) at the experimental day. The participants viewed emotionally arousing story and one week later they were asked to return to the laboratory and were given a surprise memory test. The story consisted of three phases and emotionally arousing narration occurred during phase 2. The slope of diurnal cortisol variation was calculated using a regression of log-transformed cortisol concentrations on sample collection time. Only the flat slope group did not exhibit a memory score difference among the three phases.
