The Semantic and Phonological Priming in Written Chinese Word Recognition

Semantic priming refers to a facilitation of responding speed due to the presentation of a semantically related word, while, similarly, phonological priming refers to improved recognition of a target word preceded by a word sharing the same phonological feature. Even though both of these priming effects were proved to be effective in lexical processing, it is still uncertain about whether there is difference between semantic priming effect and phonological priming effect in visual word recognition. This study focused on semantic and phonological priming effects in reading two-character Chinese words. With the lexical decision task, 18 native Mandarin speakers voluntarily took part in the experiment. It was shown that the responding speed to the target word preceded by semantic primes was faster than that preceded by phonological primes than that preceded by unrelated control primes. In other words, there are positive semantic and phonological priming effects in reading Chinese, and the effect of semantic priming is stronger than that of phonological priming. The findings supported dual-route model in lexical processing and shed more light on the studies concerning semantic and phonological priming effects in reading Chinese words.

Linguistic emergence from a networks approach: The case of modern Chinese two-character words.

The models of linguistic networks and their analytical tools constitute a potential methodology for investigating the formation of structural patterns in actual language use. Research with this methodology has just started, which can hopefully shed light on the emergent nature of linguistic structure. This study attempts to employ linguistic networks to investigate the formation of modern Chinese two-character words (as structural units based on the chunking of their component characters) in the actual use of modern Chinese, which manifests itself as continuous streams of Chinese characters. Network models were constructed based on authentic Chinese language data, with Chinese characters as nodes, their co-occurrence relations as directed links, and the co-occurrence frequencies as link weights. Quantitative analysis of the network models has shown that a Chinese two-character word can highlight itself as a two-node island, i.e., a cohesive sub-network with its two component characters co-occurring more frequently than they co-occur with the other characters. This highlighting mechanism may play a vital role in the formation and acquisition of two-character words in actual language use. Moreover, this mechanism may also throw some light on the emergence of other structural phenomena (with the chunking of specific linguistic units as their basis).

The Effects of Orthographic Neighborhood Size and the Influence of Individual Differences in Linguistic Skills During the Recognition of Chinese Words.

There are still inconsistencies as to whether frequency and orthographic neighborhood size affect the reading and recognition of Chinese words. In addition, research on Chinese reading still adheres to the view that “all skilled readers read in the same way” and pays little attention to the influence of individual differences in linguistic skills on word recognition. In this research, we studied the recognition of Chinese two-character words in a lexical decision task (LDT) by manipulating neighborhood size and word frequency and controlling the frequency of the initial constituent character. Individual differences in linguistic skills were assessed through tests of spelling and reading comprehension. The results showed that: (1) A larger orthographic neighborhood size of the initial character had a facilitative effect on Chinese word recognition. The orthographic neighborhood size effect is modulated by word frequency, but this modulation effect was not stable. (2) Spelling and reading comprehension skills are good indicators to assess individual differences in Chinese linguistic skills, and they are significantly correlated. (3) Individual differences in linguistic skills influence the neighborhood size effect, which is moderated by word frequency.

Electrophysiological correlates of character transposition in two-character Chinese word identification

The present study investigated brain activity elicited by character transposition processing of two-character Chinese words using event-related potentials (ERPs) with a two-target rapid serial visual presentation (RSVP) task. The behavioral results showed higher accuracy with canonical and transposed words than pseudowords in the short stimulus onset asynchrony (SOA, 249 ms) condition, but not in the long SOA (581 ms) condition. Additionally, relative to the pseudoword condition, the ERP results indicated that the canonical and transposed words elicited statistically less negative N250 and N400 amplitudes. Furthermore, both the canonical and transposed words revealed no significant differences in the early N100, P200, and N250 components, whereas a significant difference was observed in the N400 amplitude regardless of the SOAs between the two constituent characters, indicating less semantic activation. Taken together, our electrophysiological data indicate that early ERP components are not sensitive to Chinese character transposition. In contrast, such morpheme transposition affects the semantic processing of Chinese compound words.

Electrophysiological Correlates of Character Transposition in the Left and Right Visual Fields.

This study examined the brain activity elicited by the hemispheric asymmetries and morpheme transposition of two-character Chinese words (canonical and transposed word) and pseudowords using event-related potentials (ERPs) with a dual-target rapid serial visual presentation (RSVP) task. Electrophysiological results showed facilitation effects for canonical words with centrally presented visual field (CVF) and right visual field (RVF) presentations but not with left visual field (LVF) presentations, as reflected by less negative N400 amplitudes. Moreover, more positive late positive component (LPC) amplitudes were observed for both canonical words and transposed words irrespective of the visual fields. More importantly, transposed words elicited a more negative N400 amplitude and a less positive LPC amplitude compared with the amplitudes elicited by canonical words for CVF and RVF presentations. For LVF presentations, transposed words elicited a less negative N250 amplitude compared with canonical words, and there was no significant difference between canonical words and transposed words in the N400 effect. Taken together, we concluded that character transposition facilitated the mapping of whole-word orthographic representation to semantic information in the LVF, as reflected by the N250 component, and such morpheme transposition influenced whole-word semantic processing in CVF and RVF presentations, as reflected by N400 and LPC components.

Chinese Emotional Two-character Word Processing in Sentence Reading

Compared to the processing of the words alone, the processing of Chinese two-character words in sentences will be closer to a natural scenario, and the understanding of the sentence will be influenced by both linguistic contexts and the non-linguistic contexts. This study, in a moving-window self-paced word-by-word sentence reading task, experimentally explored the processing of Chinese sentences with emotional two-character words using reversible words and reaction time as materials and index respectively. The experimental results showed that emotional words may facilitate the processing of its following two words; there might exist subsequent processing in the third word behind the emotional word; there might exist lexical access and whole-word access, processing of morpheme positioned information in the processing of Chinese two-character words in sentence reading; the processing of Chinese two-character words may be similar with that of word alone. This study expands the research of Chinese emotional two-character words processing.

Morpheme Transposition of Two-Character Chinese Words in Vertical Visual Fields.

The present study explored the morpheme transposition process of two-character Chinese words in the upper and lower visual fields by adopting a dual-target rapid serial visual presentation paradigm. The results showed that the identification accuracy of canonical words was better in the lower visual field, whereas the accuracy of transposed words was almost identical in the upper and lower visual fields. Furthermore, there was no significant difference between canonical and transposed words at 0°, 2°, 4°, and 6° eccentricities in the upper visual field. However, the accuracy of canonical words was markedly higher than that of transposed words at 2°, 4°, and 6° eccentricities in the lower visual field. Finally, the character order errors mainly occurred at 0°eccentricity with a duration of 100ms in vertical visual fields. These findings, taken together, indicated that the character transposition affected the lexical process of two-character Chinese words in the lower visual field but not in the upper visual field, and the character order of words was more likely to be reversed at 0° eccentricity and the initial stage of visual word processing in vertical reading.

Compound word frequency modifies the effect of character frequency in reading Chinese.

In two eye-tracking studies, reading of two-character Chinese compound words was examined. First and second character frequency were orthogonally manipulated to examine the extent to which Chinese compound words are processed via the component characters. In Experiment 1, first and second character frequency were manipulated for frequent compound words, whereas in Experiment 2 it was done for infrequent compound words. Fixation time and skipping probability for the first and second character were affected by its frequency in neither experiment, nor in their pooled analysis. Yet, in Experiment 2 fixations on the second character were longer when a high-frequency character was presented as the first character compared with when a low-frequency character was presented as the first character. This reversed character frequency effect reflects a morphological family size effect and is explained by the constraint hypothesis, according to which fixation time on the second component of two-component compound words is shorter when its identity is constrained by the first component. It is concluded that frequent Chinese compound words are processed holistically, whereas with infrequent compound words there is some room for the characters to play a role in the identification process.

A Database of Chinese-English Bilingual Speakers: Ratings of the Age of Acquisition and Familiarity.

Recently, considerable attention has been given to the effect of the age of acquisition (AoA) on learning a second language (L2); however, the scarcity of L2 AoA ratings has limited advancements in this field. We presented the ratings of L2 AoA in late, unbalanced Chinese-English bilingual speakers and collected the familiarity of the L2 and the corresponding Chinese translations of English words. In addition, to promote the cross-language comparison and motivate the AoA research on Chinese two-character words, data on AoA, familiarity, and concreteness of the first language (L1) were also collected from Chinese native speakers. We first reported the reliability of each rated variable. Then, we described the validity by the following three steps: the distributions of each rated variable were described, the correlations between these variables were calculated, and regression analyses were run. The results showed that AoA, familiarity, and concreteness were all significant predictors of lexical decision times. The word database can be used by researchers who are interested in AoA, familiarity, and concreteness in both the L1 and L2 of late, unbalanced Chinese-English bilingual speakers. The full database is freely available for research purposes.

Concreteness/abstractness ratings for two-character Chinese words in MELD-SCH.

The concreteness-abstractness continuum is considered a primary dimension in the representation of semantic networks. Its theoretical importance and clinical significance are widely acknowledged. To assist and enhance future research, this study collected and evaluated concreteness/abstractness ratings for 9,877 two-character Chinese words retrieved from the MEga study of Lexical Decision in Simplified CHinese (MELD-SCH, Tsang et al, 2018). The ratings were validated through comparisons with previous rating studies on concreteness and imageability of smaller word samples. Relations of word concreteness with word frequency, age-of-acquisition, and efficiency of lexical processing were also examined. These ratings provide an additional dimension of information to two-character words in the database MELD-SCH, permitting not only more comprehensive research on the Chinese language, but also cross-language investigation of the concreteness effect between Chinese and other languages such as English and Dutch where a large database of concreteness ratings is also available.

How do word frequency and memory task influence directed forgetting: An ERP study

In daily life, it is important either to remember sometimes or to intentionally forget on other occasions. The issue of forgetting following instructions (i.e. directed forgetting, DF) has been broadly studied; however, whether the frequency of contents would matter in DF remains unclear, and the understanding of its neural mechanism in both circumstances of item memory and source memory requires improvement in depth. For these purposes, the current study manipulated word frequency and memory task to investigate relevant behavioral features and neural activities of DF. Adopting event-related potential (ERP) technique, this study applied two-character Chinese words of two types of word frequency (high vs low) in the item-method DF paradigm. During encoding, we found that the increased frontal positivity, an index of active inhibition, was regulated by both word frequency and memory task, while the enhanced parietal positivity reflecting selective rehearsal didn't fluctuate across conditions. In the course of test, three ERP old/new effects were identified: the familiarity-based FN400 and the recollection-driven LPC were both modulated by word frequency and memory task, but the right frontal old/new effect was significant solely in source memory; also, these effects provided compelling evidence for the influences of word frequency and memory task on DF. Our results reinforce the differentiation between absolute familiarity and relative familiarity in memory, reveal their sensitivity to DF, and also support the dual-process interpretation. Implications are made to examine more influential factors for future research.

The role of lexical variables in the visual recognition of two-character Chinese compound words: A megastudy analysis

To examine the effect of lexical variables on two-character Chinese compound word processing, we performed item-level hierarchical regression analyses on lexical decision megastudy data of 18,983 two-character Chinese compound words. The first analysis determined the unique item-level variance explained by orthographic (frequency and stroke count), phonological (consistency, homophonic density), and semantic (transparency) variables. Both character and word variables were considered. Results showed that orthographic and semantic variables, respectively, accounted for more collective variance than phonological variables, suggesting that Chinese skilled readers rely more on orthographic and semantic information than phonological information when processing visually presented words. The second analysis tested interactive effects of lexical variables and showed significant semantic transparency × cumulative character frequency and word frequency × cumulative character frequency interactions. The effect of cumulative character frequency was stronger for transparent words than for opaque words and was stronger for low-frequency words than for high-frequency words. However, there was no semantic transparency × word frequency interaction in reaction time. Implications of the current findings on models of Chinese compound word processing are discussed.

Tracking the Eye Movement of Four Years Old Children Learning Chinese Words.

Storybook reading is the major source of literacy exposure for beginning readers. The present study tracked 4-year-old Chinese children's eye movements while they were reading simulated storybook pages. Their eye-movement patterns were examined in relation to their word learning gains. The same reading list, consisting of 20 two-character Chinese words, was used in the pretest, 5-min eye-tracking learning session, and posttest. Additionally, visual spatial skill and phonological awareness were assessed in the pretest as cognitive controls. The results showed that the children's attention was attracted quickly by pictures, on which their attention was focused most, with only 13% of the time looking at words. Moreover, significant learning gains in word reading were observed, from the pretest to posttest, from 5-min exposure to simulated storybook pages with words, picture and pronunciation of two-character words present. Furthermore, the children's attention to words significantly predicted posttest reading beyond socioeconomic status, age, visual spatial skill, phonological awareness and pretest reading performance. This eye-movement evidence of storybook reading by children as young as four years, reading a non-alphabetic script (i.e., Chinese), has demonstrated exciting findings that children can learn words effectively with minimal exposure and little instruction; these findings suggest that learning to read requires attention to the basic words itself. The study contributes to our understanding of early reading acquisition with eye-movement evidence from beginning readers.

An early locus of associative and categorical context effects in speech production: evidence from an ERP study using the picture–word interference paradigm

ABSTRACTA picture–word interference (PWI) experiment with concurrent electroencephalogram (EEG) recording was conducted to investigate the time course of categorical and associative context effects in spoken word production. Mandarin-speaking participants were asked to name individually presented target pictures and ignore a superimposed two-character Chinese word distractor. The target and distractor were either categorically related (belonging to the same semantic category), associatively related (semantically related but not categorically related), phonologically related, or unrelated. The typical categorical interference (slower picture naming with a categorically related distractor relative to an unrelated control) was found. Furthermore, significant event-related brain potential effects were obtained in categorical and associative conditions in the time window between 275 and 450 ms post-target. By using response-locked analysis, significant effects of Target-distractor Relatedness were observed only in the associative condition within the 300-ms pre-response period. These results are consistent with the theories that assume lexical selection by competition in explaining the categorical interference effect.

Reading monomorphemic and compound words in Chinese

Abstract Two lexical decision experiments were conducted to study the recognition of two-character Chinese monomorphemic and compound words by adult native Chinese readers. In Experiment 1, the words appeared non-spaced, whereas in Experiment 2 a space was inserted between the two characters. An interaction between word type and spacing reflects a trend for spacing to slow down the recognition of monomorphemic words and speed up that of compound words. The word frequency effect was steeper for monomorphemic than compound words. The number of strokes in the first and the second character influenced the recognition time for compound words, but not for monomorphemic words. The results are interpreted in the light of the parallel dual route model of morphological processing. The holistic route is more prevalent in recognizing Chinese monomorphemic, while the morphological decomposition route is more prevalent in processing Chinese compound words.

Character Decomposition and Transposition Processes of Chinese Compound Words in Rapid Serial Visual Presentation.

Character order information is encoded at the initial stage of Chinese word processing, however, its time course remains underspecified. In this study, we assess the exact time course of the character decomposition and transposition processes of two-character Chinese compound words (canonical, transposed, or reversible words) compared with pseudowords using dual-target rapid serial visual presentation (RSVP) of stimuli appearing at 30 ms per character with no inter-stimulus interval. The results indicate that Chinese readers can identify words with character transpositions in rapid succession; however, a transposition cost is involved in identifying transposed words compared to canonical words. In RSVP reading, character order of words is more likely to be reversed during the period from 30 to 180 ms for canonical and reversible words, but the period from 30 to 240 ms for transposed words. Taken together, the findings demonstrate that the holistic representation of the base word is activated, however, the order of the two constituent characters is not strictly processed during the very early stage of visual word processing.

The effect of character contextual diversity on eye movements in Chinese sentence reading.

Chen, Huang, et al. (Psychonomic Bulletin & Review, 2017) found that when reading two-character Chinese words embedded in sentence contexts, contextual diversity (CD), a measure of the proportion of texts in which a word appears, affected fixation times to words. When CD is controlled, however, frequency did not affect reading times. Two experiments used the same experimental designs to examine whether there are frequency effects of the first character of two-character words when CD is controlled. In Experiment 1, yoked triples of characters from a control group, a group matched for character CD that is lower in frequency, and a group matched in frequency with the control group, but higher in character CD, were rotated through the same sentence frame. In Experiment 2 each character from a larger set was embedded in a separate sentence frame, allowing for a larger difference in log frequency compared to Experiment 1 (0.8 and 0.4, respectively). In both experiments, early and later eye movement measures were significantly shorter for characters with higher CD than for characters with lower CD, with no effects of character frequency. These results place constraints on models of visual word recognition and suggest ways in which Chinese can be used to tease apart the nature of context effects in word recognition and language processing in general.

Comparing the Frequency Effect Between the Lexical Decision and Naming Tasks in Chinese

In psycholinguistic research, the frequency effect can be one of the indicators for eligible experimental tasks that examine the nature of lexical access. Usually, only one of those tasks is chosen to examine lexical access in a study. Using two exemplar experiments, this paper introduces an approach to include both the lexical decision task and the naming task in a study. In the first experiment, the stimuli were Chinese characters with frequency and regularity manipulated. In the second experiment, the stimuli were switched to Chinese two-character words, in which the word frequency and the regularity of the leading character were manipulated. The logic of these two exemplar experiments was to explore some important issues such as the role of phonology on recognition by comparing the frequency effect between both the tasks. The results revealed different patterns of lexical access from those reported in the alphabetic systems. The results of Experiment 1 manifested a larger frequency effect in the naming task as compared to the LDT, when the stimuli were Chinese characters. And it is noteworthy that, in Experiment 1, when the stimuli were regular Chinese characters, the frequency effect observed in the naming task was roughly equivalent to that in the LDT. However, a smaller frequency effect was shown in the naming task as compared to the LDT, when the stimuli were switched to Chinese two-character words in Experiment 2. Taking advantage of the respective demands and characteristics in both tasks, researchers can obtain a more complete and precise picture of character/word recognition.

Conceptual fluency increases recollection: behavioral and electrophysiological evidence.

It is widely established that fluency can contribute to recognition memory. Previous studies have found that enhanced fluency increases familiarity, but not recollection. The present study was motivated by a previous finding that conceptual priming affected recollection. We used event-related potentials to investigate the electrophysiological correlates of these effects with conceptually related two-character Chinese words. We found that previous conceptual priming effects on conceptual fluency only increased the incidence of recollection responses. We also found that enhanced conceptual fluency was associated with N400 attenuation, which was also correlated with the behavioral indicator of recollection. These results suggest that the N400 effect might be related to the impact of conceptual fluency on recollection recognition. These study findings provide further evidence for the relationship between fluency and recollection.
