The Development of Preschool Children’s Awareness of Semantic Radicals in Chinese Characters

The present study investigated the development of Chinese preschool children’s awareness of semantic radicals in Chinese characters. The two specific areas of focus were the development of awareness of the category consistency of the semantic radical and awareness of the semantic radical. A sample of 55 four-year-old children and 61 five-year-old children were randomly selected from a public preschool that did not include formal literacy education in its curriculum. Experiment 1 found that the children’s awareness of the category consistency of semantic radicals had not yet developed, regardless of the configuration of characters. Experiment 2 found that the children showed no obvious awareness of the semantic radical and had a strong bias toward using phonetic radicals rather than semantic radicals to classify characters, with the bias being significant for characters of left-right configuration. The current findings suggest that Chinese preschool children have an awareness of radicals in Chinese characters and they are more sensitive to the phonetic radical than to the semantic radical and, consequently, prioritize the former.

Effects of Phonological Consistency and Semantic Radical Combinability on N170 and P200 in the Reading of Chinese Phonograms

Studies have suggested that visually presented words are obligatorily decomposed into constituents that could be mapped to language representations. The present study aims to elucidate how orthographic processing of one constituent affects the other and vice versa during a word recognition task. Chinese orthographic system has characters representing syllables and meanings instead of suffixation roles, and the majority of Chinese characters are phonograms that can be further decomposed into phonetic radical and semantic radical. We propose that semantic radical combinability indexed by semantic radicals and the effect of phonological consistency indexed by phonetic radicals would interact with each other during the reading of Chinese phonograms. Twenty-six right-handed native Chinese speakers were recruited to the study. Participants were presented with phonograms divided into four conditions following their semantic radical combinability (large vs. small) and phonological consistency (high vs. low). EEG signals were recorded throughout the covert naming task. Our results show that there is an interaction effect between phonological consistency and semantic radical combinability on the right hemisphere N170 activity while reading phonograms. Semantic radical combinability influenced the right hemisphere N170 during the process of low-consistency character reading but not high-consistency character reading. On the other hand, the left hemisphere N170 revealed a more significant activity during reading high-consistency characters and was not affected by radical combinability. In addition, while low-consistency characters revealed a larger P200 than high-consistency characters, the semantic radical combinability effect on P200 was only significant when participants were reading high-consistency characters but not low-consistency characters. These results provide new information about how ERPs are involved in word recognition within the context of interaction among orthographic and phonological dimensions.

The Graded Priming Effect of Semantic Radical on Chinese Character Recognition

This study used priming paradigm with lexical decision task to examine the effects of different levels of semantic relatedness on the identification of Chinese phonetic–semantic compound characters. Unlike previous studies that simply classify Chinese compound characters as semantically transparent or opaque, we categorize the semantic relatedness between semantic radicals (i.e., prime) and the target characters containing them into five levels: highly related (i.e., high condition; e.g., prime ± vs. target 地), moderately related (i.e., moderate condition; e.g., prime ± vs. target 场), minimally related (i.e., minimal condition; e.g., prime ± vs. target 塔), unrelated but sharing the semantic radical (i.e., form-only condition; e.g., prime ± vs. target 坏), and unrelated without sharing the semantic radical (i.e., control condition; e.g., prime ± vs. target 涌). Moreover, three stimulus-onset asynchrony (SOA)s (i.e., 57, 140, and 243 ms) were used in this study to dissociate the radical- and character-level semantic priming effects. Results revealed a graded priming effect of the semantic radical on character recognition in Chinese readers for all SOAs. More specifically, the facilitative effect of the semantic radical on character processing was most evident for the high condition, followed by the minimal, form-only, and control conditions. This suggests a graded priming effect of the semantic radical on character identification.

Differentiation of radical processing strategies in character decoding by L2 learners of Chinese according to L1-type

This study investigates the productive use of semantic and phonetic radicals for Chinese character decoding by Chinese as a foreign language (CFL) learners at different levels of L2 proficiency, focusing on the application of radical knowledge according to the learners’ L1 language families. Using a pseudo-word test developed by Williams, Clay. 2014. The development of intra-character radical awareness in L1 Chinese children: Changing strategies. Journal of the Chinese Language Teachers Association 49(2). 1–26 to measure subject preference for semantic versus phonological decoding processes, subjects are asked to match a provided definition and pronunciation with a character in a multiple choice format which included two pseudo characters designed with radicals which corresponded with the provided definition or pronunciation, respectively. The results demonstrate that reliance on semantic or phonological radicals for character identification varies according to the L1 of the CFL learners; subjects whose L1 is relatively orthographically transparent predominantly make use of phonological processing strategies at all levels of proficiency, whereas those whose L1 are more orthographically opaque demonstrate more malleable processing preferences, with relatively strong semantic radical reliance in the early stage of their language learning, and considerable variability between semantic and phonological processing at intermediate and advanced proficiency levels. The findings suggest that developmental trends of using radical decoding strategies differ among CFL learner groups with varying L1 literacy strategy preferences.

Phonological, not semantic, activation dominates Chinese character recognition: Evidence from a visual world eye-tracking study

Combining eye-tracking technique with a revised visual world paradigm, this study examined how positional, phonological, and semantic information of radicals are activated in visual Chinese character recognition. Participants’ eye movements were tracked when they looked at four types of invented logographic characters including a semantic radical in the legal (e.g., [Formula: see text]) and illegal positions ([Formula: see text]), a phonetic radical in the legal (e.g., [Formula: see text]) and illegal positions (e.g., [Formula: see text]). These logographic characters were presented simultaneously with either a sound-cued (e.g., /qiao2/) or meaning-cued (e.g., a picture of a bridge) condition. Participants appeared to allocate more visual attention towards radicals in legal, rather than illegal, positions. In addition, more eye fixations occurred on phonetic, rather than on semantic, radicals across both sound- and meaning-cued conditions, indicating participants’ strong preference for phonetic over semantic radicals in visual character processing. These results underscore the universal phonology principle in processing non-alphabetic Chinese logographic characters.

Eye-tracking the effect of semantic decoding on orthographic learning in Chinese

Most Chinese compound characters represent meaning explicitly and systematically via the semantic radical. Previous research has shown that readers can use the semantic radical to infer the meaning of unknown compound characters (i.e., semantic decoding). Yet it is unclear whether it influences reading in natural texts or facilitates orthographic learning. Across two eye-tracking experiments, we exposed adult native speakers (n= 25 and n=16) to sixteen pseudocharacters embedded in sentences. Half of the pseudocharacters contained semantic radicals related to the meaning conferred by the sentential context (i.e., transparent); the other half were unrelated (i.e., opaque). After reading, participants completed written cloze, orthographic decision and definition production tasks. In both experiments, eye-tracking results showed a reduction in fixation times and regressions over the five exposures for the pseudocharacters. The post-test outcomes provided evidence for orthographic and semantic learning. There was no difference in eye-movement measures or in written cloze and orthographic decision between transparent and opaque items, but definition was better for the transparent pseudocharacters. We conclude that semantic decoding does not affect the reading of novel compound characters in natural texts or orthographic learning, but that it does seem to assist in learning semantics.

The effectiveness of guided inductive instruction and deductive instruction on semantic radical development in Chinese character processing

This study compared the effectiveness of deductive instruction and guided inductive instruction for developing semantic radical knowledge of Chinese characters. The evaluation was conducted through a quasi-experimental 3-week intervention involving 46 intermediate learners of Chinese as a foreign language (CFL). The results indicated that guided inductive instruction generated significantly greater gains in learners’ use of radical information for radical form-meaning mapping and for Chinese character recognition and inferencing. This study further found that the effectiveness of inductive instruction in strengthening radical form-meaning mapping varied for semantic radicals of different complexity levels. These findings suggest that instructors should apply guided induction in teaching semantic radicals, but also be flexible in varying instruction in response to the complexity of semantic radicals. The findings suggest that the inductive-deductive nature of instruction and the complexity of semantic radicals are important variables to consider in future research on the learning and instruction of Chinese characters.
