Forstmann1 1 University of Amsterdam, Department of Psychology, Netherlands 2 University of Amsterdam, Department of Psychology, Netherlands 3 University of Bergen, Department of Biological and Medical Psychology, Norway 4 University of Connecticut, Department of Educational Psychology, United States The Linear Ballistic Accumulator modeling framework (LBA) provides an elegant and simple way of summarizing behavioral decision-making data (Brown & Heathcote, 2008). In addition, the specific parametrization of the LBA model may be used to identify neural correlates of strategic decision making-processes (e.g., Forstmann et al, 2008; 2010). However, the LBA does not provide insights in the properties of single trials. In this work, we study how the parameters in default LBA emerge from parameters on a single trial level using Markov-Chain Monte Carlo simulations of the parameter distributions. This enables us to study individual trial fluctuations in neural activation and how these relate to decision making.
