In 7 experiments the authors investigated the locus of word frequency effects in speech production. Experiment 1 demonstrated a frequency effect in picture naming that was robust over repetitions. Experiments 2, 3, and 7 excluded contributions from object identification and initiation of articulation. Experiments 4 and 5 investigated whether the effect(More)
Lexical access in object naming involves the activation of a set oflexical candidates, the selection of the appropriate (or target) item, and the phonological encoding of that item. Two views of lexical access in naming are compared. From one view, the 2-stage theory, phonological activation follows selection of the target item and is restricted to that(More)
Timed picture naming was compared in seven languages that vary along dimensions known to affect lexical access. Analyses over items focused on factors that determine cross-language universals and cross-language disparities. With regard to universals, number of alternative names had large effects on reaction time within and across languages after target-name(More)
Picture naming is a widely used technique in psycholinguistic studies. Here, we describe new on-line resources that our project has compiled and made available to researchers on the world wide web at The website provides access to a wide range of picture stimuli and related norms in seven languages. Picture naming norms,(More)
f ur K unstliche Intelligenz GmbH, DFKI) in the Computational Linguistics area. I am grateful to these institutes for their support. Many, many people have helped me not to get lost during the development of this thesis. Hans Uszkoreit, my main supervisor, provided a motivating, enthusiastic, and critical atmosphere during the many discussions we had. It(More)
The degree of interference caused by different kinds of stimuli on memory for tonal pitch was studied. Musically trained and untrained subjects heard a sequence of two tones separated by an interval of 5 sec. The tones were either identical in pitch or differed by a semitone. Subjects had to decide whether the tones were identical or not. The interval was(More)
In the present study musicians and normal control subjects performed an S1-S2 pitch comparison task, which included the presentation of intervening tones during the retention interval. The time for encoding and storing the pitch of S1 was varied between 200 and 1,500 ms by changing the pause between the S1 offset and the onset of the intervening tones.(More)
In 2 picture-naming and 2 grammaticality judgment experiments, the authors explored how the phonological form of a word, especially its termination, affects gender processing by monolinguals and unbalanced bilinguals speaking German. The results of the 2 experiments with native German speakers yielded no significant differences: The reaction times were(More)
In 5 picture-word interference experiments the activation of word class information was investigated. The first experiment, in which subjects used bare nouns to describe the pictures, failed to reveal any interference effect of noun distractor words as opposed to closed-class distractor words. In the next 4 experiments the pictures were named by using a(More)
