Abstract
Zusammenfassung. Im Anschluß an eine einführende Übersicht zu experimentalpsychologischen Untersuchungen unter Verwendung von Homonymwörtern werden die Ergebnisse einer Normierungsstudie von 68 deutschen Homonymen an einer Normalpopulation von 100 gesunden Probanden dargestellt. Berichtet werden Frequenz und Polarität der Homonyme sowie U-Werte (Index der Ambiguität). 49 Homonyme wiesen eine eindeutige semantische Präferenz für ein Bedeutungsfeld auf, 7 Homonyme waren balanciert und bei 12 Homonymen entfielen auf die inferioren Wortbedeutungen jeweils weniger als 5 % der Nennungen. Studien 2a und 2b replizieren frühere Befunde zur Resolution semantischer Ambiguität. Für diskordante Triplett-Bedingungen ließen sich bei längerem Interstimulusintervall zwischen Homonym und Zielreiz Hemmeffekte nachweisen, während eine (insignifikante) Reaktionserleichterung bei kürzerem Intervall gefunden wurden. Die Ergebnisse von Studie 2 bestätigen kontext-sensitive Modelle der Homonymverarbeitung, wonach es im Anschluß an eine initiale Aktivierung distinkter Wortbedeutungen eines Homonyms zu einer kontextgeleiteten Inhibition zusammenhangsferner Assoziationen kommt.
Abstract. Norms for 68 German homophonic homographs were collected in a normal population comprising 100 subjects. Frequency and polaritiy as well as U-scores (index of ambiguity) are presented. 49 of the words revealed a clear dominance for only one meaning. 7 homophonic homographs were balanced, and for 12 words less than 5 % of all associations were given for each of the inferior meanings. Studies 2a and 2b are a replication of previous findings on the resolution of semantic ambiguity. Inhibition effects were revealed for discordant triplet conditions which contained a long interstimulus interval between homograph and target, whereas an (insignificant) facilitation effect occured for trials with a shorter interval. Results of study 2 are in line with context-sensitive models which claim that after the initial activation of all meanings of a homograph a context-guided process leads to a suppression of context-irrelevant homograph information.
