Algorithmic basis of reward-based decisions in dynamic environment In probabilistic reward foraging task (Fig.1A) animals’ choices tend to reflect the previous rewards, in a way that biases animals’ future choices to options from which they recently received the rewards. In addition to the reward history effects, curiously animals choices also depend on the previous choices, phenomenon that is not easily explained by the current computational models (Fig.1B). We are formulating normative accounts of why choice history effects should persist in animals. The insight into this phenomenon may give

As a father of six, Donald Torry, PhD, has some experience with pregnancy. Helping women who develop preeclampsia has become his life’s work. Preeclampsia is a pregnancy condition in which high blood pressure and protein in the urine develop after the 20th week (late second or third trimester). Preeclampsia develops in 5-10 percent of pregnancies and, aside from anti-hypertensives to try to control spiraling blood pressure, the only “cure” is delivery.
