This article presents a study of errors made by hearing adult L2 learners of Swiss German Sign Language
(Deutschschweizerische Gebärdensprache, DSGS). As part of a statistical analysis of single-parameter errors,
movement was found to be the parameter most susceptible to errors, followed by location, orientation, and handshape. An analysis
of production errors with respect to combinations of manual parameters was also conducted, something that previously has not been
undertaken. The parameter combination most frequently involved in errors was movement with location. Possible aspects contributing
to the higher error rate for movement are suggested, among which are the inherent complexity of the movement parameter. Finally,
the article discusses factors influencing the judgment of errors.
