I was an undergraduate student in Psychology at the University of Lisbon, studied for two years at the Université de Liège, Belgium, and then, in 1993, obtained my PhD. at Duke University, USA. My doctoral research on the conditions in which pigeons generate highly variable, random-like behavior received the Annual Dissertation Award from Division 25 of the American Psychological Association. From 1994 till 2000, I was a professor at Indiana University (first Assistant and then Associate with tenure). In 2000 I moved to the University of Minho where I set up the first laboratory in Portuguese Psychology Departments to study animal learning and cognition (e. g., how animals perceive time, discriminate numbers, or choose). In 2019, I joined the University of Aveiro. In most of my studies, I contrast data with the predictions of simple quantitative models of behavior. In addition to the Psychology of Learning, I have interests in the Teaching of Statistics in Psychology, Evolutionary Biology, Philosophy, and the History of Psychology. My work has been published in various journals (e.g., American Psychologist, Psychological Review, Journal of the Experimental Analysis of Behavior, Psychological Science, Behavior and Philosophy, etc.) and funded by The National Institutes of Health (NIMH - in the USA) and the Portuguese Science Foundation. I served as Chief Editor of the journal Behavior and Philosophy and as Associate Editor of the journals Learning and Behavior, Psychonomic Bulletin & Review, and the Journal of the Experimental Analysis of Behavior. I have been a member of the editorial board of several other journals. I was the Program Chair and then the President of the American Society for the Quantitative Analysis of Behavior. From 2005 till 2011 I was the first president of the Portuguese Association of Experimental Psychology.
