I'm interested in how we learn about apparently simple relationships between events based on our experience with these events, for example how we learn the relationship between "raining" and cues that precede "raining", e.g. a certain kind of clouds, people caring an umbrella and the cloud symbol on today's front page of the local newspaper. To investigate the processes and mechanisms responsible for such learning, I'm using mainly associative learning models as a theoretical basis and human causal learning and eye tracking during computer games as empirical counterparts.
Flexible representations in associative learning - a part/whole
or a capacity question?
Postdoctoral Fellowship by the German Academic Exchange Service (DAAD) and the University of Sydney, 2010-2012.
This project is linked to the debate over the way predictive stimuli and signals are represented and processed during learning. Across several experiments and papers, we established that humans differ in the way they represent and process stimuli. Furthermore and in contrast to the standard framing of the debate, we investigate whether the crucial question is not whether the stimulus representation is configural or elemental but rather whether the representation of complex stimuli is affected by normalisation processes.
In order to model the flexibility and complexity of stimulus processing during learning, complex mathematical theories are necessary. In addition to the experimental verification of these theories, one contributions of this projects to the field of associative learning consists in providing tools and examples for computational modelling of such associative learning theories
