| summary | Cognitive models of decision making often focus on simple decisions between two alternatives (e.g., Ratcliff, 1978). Typically, the assumption is that there is a perceptual stage, a decision stage, and a response stage, and that differences in behavior are due to differences in the decision stage. However, many decisions require a choice from more than two options, and the decision making behavior may result form a complex interaction between multiple
processing stages.
This is particularly clear in language production, where many stages are involved at which a choice has to be made to eventually utter a word (Levelt, 1989). For example, first a message that is going to be conveyed is chosen, and then an appropriate syntactic form is selected, and finally the required motor program is selected.
During my talk I will introduce our modeling approach to these complex choice problems (Van Maanen et al., 2009; Van Maanen & Van Rijn, 2010). I will briefly discuss the cognitive architecture ACT-R (Anderson, 2007) in which our models are rooted, as well as traditional models of decision making. Finally I will show how a combination of these two modeling approaches provides a new perspective on behavior in the Stroop task and picture-word interference, as well as on the role of attention in these tasks. |
