Research

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

 

Learned Predictiveness und Predictability and how previous experience influence subsequent learning
DFG Project, 2014-2017.

As we learn faster about stimuli that previously were highly predicitive, do we also learn faster about stimuli that were highly predictable? This project investigates whether the successful prediction of an event in the past influences learning about this event in new situations. It focusses on questions concerning the rate at which humans learn about a stimulus and its associations with other events, its associability. First, how is associability influenced by the extent to which that stimulus has been predictable in the past, that is the predictability of the stimulus? Second, how does the influence of stimulus predictability interact with the already known effects of the utility of the stimulus in predicting other events, that is the learned predictiveness of the stimulus? In addition to the causal learning paradigm, which is the standard procedure for the learned predictiveness effect, the current project will take advantage of an original paradigm for classical conditioning of the gaze that was developed in cooperation with J. Harris and E. Livesey from the University of Sydney and allows the simultaneous measurement of learning and attentional effects.

This project is done in close collaboration with Evan Livesey, University of Sydney, and my PhD student Wei Liu.


Connecting associative learning theories with other research fields

When I started, my research focused on eye blink conditioning and skin conductance conditioning. During my PhD, I switched to more cognitive paradigms, like causal and predictive learning. This familiarity with historically rather distinct methods and concepts allows me to approach my projects from a unique position and the question which learning processes control and interact in which paradigm remains a constant thread in my research. In collaborations with colleagues, I'm also interested where and which of these processes govern behaviour outside the conditioning laboratory, in particular the clinical relevance of conditioning and learning processes.
