Prefixed Word Forms in the German Mental Lexicon Ingrid Sonnenstuhl Meike Hadler Helga Weyerts Harald Clahsen University of Düsseldorf Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002
The Lexical Representation of Derivational Word Forms • Full form storage of all complex word forms, morphological structure plays no role.(e.g. Butterworth 1983; Rumelhart & McClelland 1986; Bybee 1995) • Full form storage of all complex word forms, morphological structure plays some role.(e.g. Lukatela, Gligorijevic, Kostic, Savier & Turvey 1980; Andrews 1986; Feldman & Fowler 1987; Schriefers, Friederici & Graetz 1992) • Decomposition of complex word forms.(e.g. Taft & Forster 1975; Taft 1979, 1981) • Transparency determines the processing of complex word forms.(e.g. Henderson, Wallis & Knight 1984; Feldman 1994; Marslen-Wilson, Tyler, Waksler & Older 1994; Drews & Zwitserlood 1995) • Different processing of prefixed and suffixed words.(e.g. Marslen-Wilson, Tyler, Waksler & Older 1994) Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002

Research Questions • Do the results from suffixed forms generalize to prefixed forms? • How are derivational forms with a limited productivity represented? Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002

Experiment 1 Frequency Effects instabil UnprimedLexical Decision Access Representations Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002
Experiment 1 Frequency Effects • Prediction: Derived word forms are stems by themselves • frequency effects for derived stems Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002
Experiment 1 Frequency Effects Results • Word- form frequency effects for both derivational forms • Full-form representations • for fully productive • and less productive • prefixed adjectives Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002

Experiment 2 Cross-Modal Priming Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002
Experiment 2 Cross-Modal Priming Predictions • No decomposition: Separate entries for derivational forms • reduced priming • Decomposition: Repeated access to the same stem • full priming • Dual-Mechanism hypothesis: • full priming for un- adjectives • reduced priming for in- adjectives Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002
Experiment 2 Cross-Modal Priming Results • Full priming for un- forms • decomposed lexical representations • Reduced priming forin- forms • full-form lexical representations Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002

Summary • Full-form frequency effects for all derivational forms • Full-form access representations for all derivational forms • Reduced priming for in- adjectives • Storage of derivational forms with limited productivity and transparency • Full priming for derived un- adjectives • Full priming for derived -ung nouns • Full priming for -chen diminutives • Decomposition of transparent and fully productive derivational forms Third International Conference on the Mental Lexicon, Banff, October 5 - 8 2002
