Research Interest: Understanding human thinking and especially human problem
solving, reasoning, and decision making:
A model of human reasoning, AMBR,
has been developed which is supposed to unify analogy. deduction, and generalization. The
model integrates the subprocesses of memory access, mapping, transfer, evaluation, and
perception and learning in perspective. Access, mapping, transfer, and evaluation are
running in parallel and interacting with each other, which is in contrast with the
dominating sequencial models of processing.
AMBR is build on a general cognitive architecture, DUAL,
which integrates the symbolic and connectionist approches at the mirco-level. All
cognitive processes modeled on DUAL are emergent computations from the collective behavior
and interactions of many hybrid micro-agents.
Understanding the role of context for human thinking and the dynamics of context
influence on human cognitive processes. A theory of context has been proposed,
Context and priming effects on reasoning and decision-making have been demonstrated in
psychological experiments and simulated in DUAL and AMBR. Thus AMBR accounts for the
dynamic context-sensitive nature of human thought.
