**Short Abstract**
We explore an information-theoretic account to the usage of topic drop
(Ross 1982; Fries 1988), i.e. the omission of a preverbal constituent in
German, based on data from a corpus study and two rating studies. We
investigate the influence of several factors that impact the processing
effort of topic drop: grammatical person, verb surprisal, verb type and
topicality. To account for the results, we argue that the use of topic
drop follows information-theoretic processing constraints as modeled by
the /Uniform Information Density hypothesis/ (Levy & Jaeger 2007).
