My work is focussed on the study and refinement of psychological theories by means of formal modeling and careful experimentation. Theories in cognitive psychology often take the form of information-processing models with impressive explanatory power, but with a relative weak link to biological constraints. On the other hand, much work in neuroscience has the inverse problem. The goal of my current work is to integrate these fields by adapting existing psychological theories to low-level neurobiological constraints. A prime example is my work on interval (or brain) timing in which I am redefining the pacemaker-accumulator theories that have been prominent since the 1960s with models based on neurobiological constraints, while retaining the explanatory power of the original theories.

Wetenschap in gewone taal

["Science in plain language"]

Voor een studentenblad heb ik een inleidend stuk geschreven over het onderzoek dat ik samen met Niels Taatgen en John Anderson naar tijdswaarneming heb gedaan. Dit stuk is geschreven met het idee dat het ook voor de niet-expert goed leesbaar moet zijn. Mocht je geinteresseerd zijn in tijdswaarneming en cognitieve architecturen, kan je het stuk hier downloaden: Tijd voor Architecturen.
Samen met een afstudeerstudent heb ik een onderzoek gedaan naar hoe leren geoptimaliseerd kan worden. Dit onderzoek heeft laten zien dat de effectiviteit van leren sterk verbeterd kan worden als we gebruik maken van kennis over het menselijk geheugen. Een verslag van dit onderzoek kan hier gedownload worden: SlimStampen: Optimaal leren door kalibratie op kennis en vaardigheid.
Adamsappel is het populair wetenschappelijke TV programma van de Rijksuniversiteit Groningen. Een interview dat zij met mij hebben gehouden over een model dat Niels Taatgen heeft gemaakt van het spel Set! is hier te bekijken: Adamsappel.
