My research interests are: sequential collaboration, wisdom of crowds, cultural consensus theory, and methods avoiding scoail desirablity in questionnaires. Right now my research mainly focuses on sequential collaboration, a collaboration type in which contributors correct each other and add information sequentially.

About a decade ago, Super-recognizers were first descirbed as individuals with exceptional face identity processing abilities. Since then, various tests have been developed or adapted to assess individuals' face identity processing abilities and identify Super-Recognizers. The extent literature suggests that Super-Recognizers may be beneficial in p...
Cultural consensus theory is a model-based approach for analyzing responses of informants when correct answers are unknown. The model provides aggregate estimates of the latent consensus knowledge at the group level while accounting for heterogeneity in informant competence and item difficulty. We develop a new version of cultural consensus theory...
Online collaborative projects in which users contribute to extensive knowledge bases such as Wikipedia or OpenStreetMap have become increasingly popular while yielding highly accurate information. Collaboration in such projects is organized sequentially, with one contributor creating an entry and the following contributors deciding whether to adjus...

Many collaborative online projects such as Wikipedia and OpenStreetMap organize collaboration among their contributors sequentially. In sequential collaboration, one contributor creates an entry which is consecutively encountered by other contributors who then decide whether to adjust or maintain the presented entry. Sequential collaboration yields...
Big data are not yet commonly used in psychological research as they are often difficultto access and process. One source of behavioral data containing both spatial andthematic information is OpenStreetMap, a collaborative online project aiming to developa comprehensive world map. Besides spatial and thematic information about buildings,streets, an...
The phenomenon of sequential collaboration and future research perspectives.
In cultures with left-right-script, agentic behavior is mentally represented as following a left-to-right trajectory, an effect referred to as the Spatial Agency Bias (SAB, Suitner and Maass, 2016 ). In this research, we investigated whether spatial representations of activities are universal across activities by analyzing the opposite concepts of...
Previous research has demonstrated that people remember information that is (emotionally) incongruent to their expectations, but it has left open the question if this memory enhancement has also an influence on our later actions. We investigated this question in one pilot study and two experiments. In all studies, participants first interacted with...
People perceive the environment in various idiosyncratic ways, letting them conceptualize places differently. Representation in a data set and communication about places, however, create the need to reach agreement in the place a symbol or word represents. People have thus to integrate their views about a place. In this paper, we discuss how idiosy...
