SQAB Tutorial: An Invitation to Probability With Spreadsheet Simulations
Saturday, May 26, 2012
1:00 PM–1:50 PM
608 (Convention Center)
Area: EAB; Domain: Basic Research
Chair: Alliston K. Reid (Wofford College)
Presenting Authors: : ARMANDO MACHADO (Universidade do Minho)

In this tutorial I will review some fundamental ideas concerning the theory of probability. I will concentrate on the Poisson, Exponential, and Gamma random variables, review their properties, show how they are interrelated, illustrate their uses in modelling behaviour and learning, and simulate them in a spreadsheet. I will conclude with some notes concerning the Poisson Process and apply it to timing and concurrent choice.

ARMANDO MACHADO (Universidade do Minho)
Armando Machado was an undergraduate student in Portugal, studied for two years in Belgium, and then in 1993 obtained his Ph.D. with John Staddon at Duke University. His doctoral research on the conditions in which pigeons generate highly variable behavior received the Annual Dissertation Award from Division 25 of APA. From 1994 till 2000 Armando was a professor at Indiana University (first Assistant and then Associate with tenure). In 2001 he moved to the University of Minho in the North of Portugal where he continues to study a variety of issues pertaining to behavior and learning (e.g., time and number discrimination, choice). In most of his studies, Armando contrasts data with the predictions of simple mathematical models of behavior. His work has been published in various journals (e.g., JEAB, Psychological Review, Psychological Science, Behavior and Philosophy, etc) and funded by NIH and the Portuguese Science Foundation. He served as Associate Editor of Psychonomic Bulletin & Review and is currently a member of the editorial board of several journals. In collaboration with Francisco Silva from the University of Redlands, Armando has published a graphics-based workbook to be used in the teaching of learning. He is past Program Chair and past President of the Society for the Quantitative Analysis of Behavior.
