The use of the “ Take The Best ” Heuristic under different conditions , modeled with ACT-R Stefani Nellen

Empirical evidence is accumulating which suggests that the use of the “Take The Best” Heuristic (TTB), one of the “Simple Heuristics that make us smart” (Gigerenzer, Todd & the ABC Research Group) can be induced by factors such as appropriate feedback (Otto & Rieskamp, 2002) or the cost of information search (Bröder, 2000). Using an ACT-R simulation, I demonstrate that these findings can be due to the fact that the utility of heuristics can be learned under some conditions, but not under others: The use of heuristics is conceptualized as being rooted in reaction rather than selection. The theoretical and practical implications of both views are discussed.
