The study assessed the eye movements of 60 adult German readers during silent reading of target words, consisting of two and three syllables, embedded in sentences. The first objective was to assess whether the inhibitory effect of first syllable frequency, which was up to now primarily shown for isolated words, generalises to natural reading. The…

In this paper we investigate whether homophones have "shared" (e.g., Dell, 1990; Levelt, Roelofs, & Meyer, 1999) or "independent" (e.g., Caramazza, Costa, Miozzo, & Bi, 2001) phonological representations. We carried out a homophone reading aloud task with low frequency irregular homophones and matched low frequency…

Two experiments are reported which investigated morphological processing in English using bilexemic compound words. Long and short compound words were presented in neutral sentences and eye movements were recorded while participants read the sentences to investigate the time course of compound word recognition. In Experiment 1, the frequency of…

In three experiments, we explore the effects of phonological properties such as neighbourhood density and frequency on speech production in Spanish. Specifically, we assess the reliability of the recent observation made by Vitevitch and Stamer (2006), according to which the neighbourhood effect in Spanish has a reverse polarity to that observed in…

In psycholinguistic research, there is still considerable debate about whether the type or token count of the frequency of a particular unit of language better predicts word recognition performance. The present study extends this distinction of type and token measures to the investigation of possible causes underlying syllable frequency effects.…

Do native readers segment polysyllabic words based on orthographic/morphological criteria or phonological criteria? Research by Taft (1979, 2001) argues in support of the former, as readers were faster in split-word lexical decision tasks when the words were segmented by orthographic/ morphological principles based on Basic Orthographic Syllable…

Assessed encoding of suffixed words (both derivations and inflections) by monitoring eye movements during reading English sentences in which target words were embedded. Whole-word frequency and root frequency were independently manipulated, where pairs of words differing on one variable and matched on the other were inserted into the same sentence…

Elicited acceptability ratings from native-English-speaking adults for regular and irregular past tense forms and their stems, in sentence contexts, analyzing them for frequency and phonological neighborhood effects. Results indicate that irregular past tenses are retrieved from associative memory, whereas regular past tenses are produced by a…

Atypical vocabulary has been reported as one of the most notable features of the language of adolescents and adults with Williams syndrome (WS), including use of unusual or low frequency words. Two hypotheses were identified regarding the developmental origins of this phenomenon. The "intra-lexicon" hypothesis views the cause in terms of…

Four visual lexical decision experiments using the masked priming paradigm tested for effects of prime word frequency and cumulative root frequency with primes varying in degree of morphological and orthographic overlap with free root targets in French. (Author/VWL)

Three experiments used the differential frequency effect as a diagnostic tool to investigate the mental representation of disyllabic compound words in Mandarin Chinese. The results indicated that, when both word frequency and morpheme frequency were held constant, high-frequency first syllables slowed responses to real words. (41 references) (MDM)

Examines Nickels's claim that interactive models of lexical access in speech production cannot account for naming data from a group of anomic patients. This paper reiterates that the behavior of connectionist models is not easily predictable without running the appropriate simulations, and discusses the role of frequency in lexical access in…

Different models of spoken word production make different predictions regarding the extent of effects of certain word properties on the output of that model. This article examines these predictions with regard to the effect of these variables on the production of semantic and phonological errors by aphasic subjects. (60 references) (Author/CK)

Current models of spoken-word recognition describe access to lexical representations in terms of activation and decay. This research investigated an important aspect of activation: the impact of processing time. The results showed a separable impact of time and signal on the activational state of lexical elements.
