  ABSTRACT: The present study aimed to test the Sense Model of cross-linguistic masked translation priming asymmetry, proposed by Finkbeiner et al. (J Mem Lang 51:1-22, 2004), by manipulating the number of senses that bilingual participants associated with words from both languages. Three lexical decision experiments were conducted with Chinese-English bilinguals. In Experiment 1, polysemous L2 words and their L1 Chinese single-sense translation equivalents were selected as primes and targets. In Experiment 2, single-sense L1 words and their L2 translation equivalents with polysemous senses severed as primes and targets. We found translation priming effects in the L1-L2 direction, but not in the L2-L1 direction. In Experiment 3, presentation time of the L2 priming stimulus was prolonged, and significant translation priming effects were observed in the L2-L1 direction. These findings suggest that the Sense Model does not adequately explain cross-language translation priming asymmetry. The sense numbers of primes and targets, as well as the activation proportion of these senses between them, were possibly not the primary reason for cross-language translation priming asymmetry. The revised hierarchical model (Kroll and Stewart in J Mem Lang 33:149-174, 1994) and the BIA+ model (Dijkstra and van Heuven in Bilingualism Lang Cognit 5:175-197, 2002) better explain the cross-language translation priming asymmetry we found.

• Article: Age of acquisition affects the retrieval of grammatical category information.

  ABSTRACT: This study investigated age of acquisition (AoA) effects on processing grammatical category information of Chinese single-character words. In Experiment 1, nouns and verbs that were acquired at different ages were used as materials in a grammatical category decision task. Results showed that the grammatical category information of earlier acquired nouns and verbs was easier to retrieve. In Experiment 2, AoA and predictability from orthography to grammatical category were manipulated in a grammatical category decision task. Results showed larger AoA effects under lower predictability conditions. In Experiment 3, a semantic category decision task was used with the same materials as those in Experiment 2. Different results were found from Experiment 2, suggesting that the grammatical category decision task is not merely the same as the semantic category decision task, but rather involves additional processing of grammatical category information. Therefore the conclusions of Experiments 1 and 2 were strengthened. In summary, it was found for the first time that AoA affects the retrieval of grammatical category information, thus providing new evidence in support of the arbitrary mapping hypothesis.

• Article: [Research progress of effect of donor nerve on regeneration of recipient nerve in end-to-side neurorrhaphy].

  ABSTRACT: To review the researches of donor nerve's promoting effect on regeneration of recipient nerve in end-to-side neurorrhaphy at home and abroad. The latest original literature concerning donor nerve's accelerating effect on regeneration of recipient nerve was extensively reviewed. Proper nerve cutting may promote nerve regeneration. But how to quantize the cutting volume was still a challenge. It is important to research the donor nerve in neurorrhaphy, which can provide evidence for clinical neurorrhaphy so as to achieve good results.

• Article: Language nonselective access to phonological representations: evidence from Chinese-English bilinguals.

  Huixia Zhou, Baoguo Chen, Meiying Yang, Susan Dunlap
  [show abstract] [hide abstract]
  ABSTRACT: Four experiments with Chinese-English bilinguals were conducted in order to investigate the hypothesis of language nonselective access to an integrated lexicon for bilingual phonological representations. Results of a naming task (in Experiments 1 and 2) and a lexical decision task (in Experiments 3 and 4) showed homophone priming effects regardless of priming direction (English to Chinese, or Chinese to English) or English proficiency. Our findings are compatible with the BIA+ model of bilingual processing, provide further support for the hypothesis of language nonselective access to an integrated lexicon for bilingual phonological representations, and extend the hypothesis to language pairs with very different writing systems.

• Article: Age of acquisition affects early orthographic processing during Chinese character recognition.

  ABSTRACT: Three experiments investigated age of acquisition (AoA) effects on early orthographic processing during Chinese character recognition. In Experiment 1, we measured the accuracy of identification of brief masked characters, accuracy was higher for early compared to late acquired characters. In Experiment 2, the visual duration threshold (VDT) was measured for both early and late acquired Chinese characters. The results showed that early acquired characters were successfully identified at shorter display durations than late acquired characters. Significant AoA effects were also found in Experiment 3, using a lexical decision task requiring mainly orthographic processing (discriminating real Chinese characters from orthographically illegal and unpronounceable characters). In summary, three experiments provide converging empirical evidence, for AoA effects on the early orthographic processing stages of Chinese character recognition. These results suggest that AoA effects during word identification go beyond the phonological or semantic processing stages. These results aslo provide cross-linguistic evidence for an AoA effect on early perceptual processing during identification.

• Article: Frequency trajectory effects in Chinese character recognition: evidence for the arbitrary mapping hypothesis.

  ABSTRACT: Frequency trajectory is a better measure to investigate age-limited learning effects than age of acquisition (AoA) ratings (Zevin, J. D., & Seidenberg, M. S. (2002). Age of acquisition effects in word reading and other tasks. Journal of Memory and Language, 47(1), 1-29). The current study uses frequency trajectory as a variable to investigate age-limited learning effects in Chinese character recognition, and tests predictions of the arbitrary mapping hypothesis as applied in a non-alphabetic writing system. In Experiment 1, regression analyses showed that, compared to rated AoA, frequency trajectory of characters was less affected by other lexical properties, and could explain a significant proportion of variance of AoA. In Experiment 2, the frequency trajectory and predictability from orthography to pronunciation of characters were orthogonally manipulated in a character naming task. The frequency trajectory effect appeared only for the arbitrary mapping condition. In Experiment 3, frequency trajectory and predictability from orthography to meaning of characters were manipulated in a semantic category judgment task. The frequency trajectory effects were found only when the mapping from orthography to semantic is less consistent. In summary, the study confirmed that AoA is a genuine factor affecting word processing, and the AoA effects were limited to those situations in which mapping between input and output representation was arbitrary. These results provide strong cross-linguistic evidence in support of the arbitrary mapping hypothesis.

• Article: Chinese subject-relative clauses are more difficult to process than the object-relative clauses.

  ABSTRACT: This paper presents an experiment that compared high and low working memory span readers' abilities to process Chinese subject-relative and object-relative clause structures in a self-paced reading paradigm. Comprehension performance results indicated that the object-relative structure was easier to understand than the subject-relative structure. Reading time results showed that participants with low working memory span read the subject-relative structures more slowly than the object-relative structures, but there was no reading time difference for the high working memory span participants. The experiment provides further evidence that the Chinese subject-relative clause structure is more difficult to process than the Chinese object-relative clause structure, especially for low working memory span individuals. Furthermore, these results support a syntactic storage account of the observed complexity difference.
