This study investigates the contributions of semantic, phonological, and orthographic factors to morphological awareness of 413 Chinese-speaking students in Grades 2, 4, and 6, and its relationship with reading comprehension. Participants were orally presented with pairs of bimorphemic compounds and asked to judge whether the first morphemes of the words shared a meaning. Morpheme identity (same or different), whole-word semantic relatedness (high or low), orthography (same or different), and phonology (same or different) were manipulated. By Grade 6, children were able to focus on meaning similarities across morphemes while ignoring the distraction of form, but they remained influenced by whole-word semantic relatedness. Children's ability to overcome the distraction of phonology consistently improved with age, but did not reach ceiling, whereas the parallel ability for orthography reached ceiling at Grade 6. Morphological judgment performance was a significant unique predictor of reading comprehension when character naming and vocabulary knowledge were accounted for.

The research reported in this paper investigated the effects of semantic relatedness of words (closely related vs. distantly related) and morpheme type (free morpheme vs. bound morpheme) on young Chinese children's homophone awareness, an aspect of morphological awareness, in two experiments. The first experiment was a cross-sectional study including 39 children in a beginning kindergarten class, 39 children in an intermediate kindergarten class, and 36 children in a senior kindergarten class. The second experiment was a 7-month longitudinal study involving 43 first graders and 50 second graders at the beginning of the study. In both experiments, the children judged whether orally presented words shared the same morpheme or contained homophonous morphemes. The results suggest that homophone awareness emerges in Chinese children in the kindergarten years. Children's morpheme identification is facilitated by the semantic proximity of words that share a morpheme, and awareness of free morphemes is developed before that of bound morphemes. Furthermore, although semantic relatedness is the most prominent factor in kindergarten, its effect varies as a function of morpheme type in the early primary grades. Our research sheds light on the developmental course of morphological awareness and the factors that influence it.Morphemes are the smallest units of meaning in language. In all languages, morphemes are combined in a rule-based manner to form morphologically complex

Qian and Schedl's Depth of Vocabulary Knowledge Test was administered to 31 native-speaker undergraduates under an "unconstrained" condition, in which the number of responses to headwords was unfixed, whereas a corresponding group (n = 36) completed the test under the original "constrained" condition. Results revealed lower accuracy in the unconstrained condition and in paradigmatic versus syntagmatic responses. Native speakers failed to reach the 90% criterion on most unconstrained and many constrained items. Although certain modifications could improve such a test (e.g., eliminating psycholinguistically anomalous headwords, such as adjectives, or presenting responses to headwords discontinuously), two intransigent problems impede test validity. First, collocates in the mental lexicon differ in tightness and vary across dialects, sociolects, and age groups. Second, it is more serious that second-language Depth of Vocabulary Knowledge Tests are likely spot checks of metalinguistic knowledge rather than depth tests that reflect what learners would actually produce in spontaneous utterances.The last two decades have seen a renewal of interest in vocabulary and a surge in the number of studies on second-language (L2) lexical acquisition. Despite this progress, L2 lexical studies frequently remain uninformed by current psycholinguistic research. Nowhere is this more evident than in the case of lexical testing and the linguistic and psycholinguistic frameworks within which lexical testing is conducted. Standardized, valid, and reliable vocabulary measures are still scarce, particularly so when one considers languages spoken outside the few countries able to sustain lexical testing research. As would be expected, the situation is the best in the case of English, for which there are now quite a few lexical tests
