This suggests iconicity as a functional mechanism in language. To examine the underlying cognitive processes, a holistic operationalization of iconicity in ...

In this dissertation, I present the advantages of new state-of-the-art item and person sampling procedures in the context of personality development research (manuscript 1). ...
