Stroke Encoding Processes of Chinese Character During Sentence Reading.

The present study was conducted to examine whether traditional and simplified Chinese readers (TCRs and SCRs) differed in stroke encoding in character processing by an eye-tracking experiment. We recruited 66 participants (32 TCRs and 34 SCRs) to read sentences comprising characters with different proportions and types of strokes removed in order to explore whether any visual complexity effect existed in their processing of simplified and traditional Chinese characters. The present study found a cross-script visual complexity effect and that SCRs were more influenced by visual complexity change in lexical access than were TCRs. In addition, the stroke-order effect appeared to be more salient for TCRs than for SCRs.

Dual surface structured light vision system based on multidimensional parameter coding.

A dual surface structured light vision system based on the theory of multidimensional parameter coding is proposed in this paper that can provide a new high-performance and adaptive encoding robot vision perception system. Specifically, the dual surface structured light consists of an auxiliary light source and a principal structured light. Scene images from the auxiliary structured light determine the parameters of the principal structured light. The vision process system can adaptively encode the principal structured light according to types and numbers of parameters. The image formed by the encoded principal structured light can reflect the depth change details of the target object and guide the robot to locate the target object quickly and accurately. The simulation and industrial experiments show that the dual surface structured light vision system has wider application scenarios and higher accuracy than the traditional structured light vision system. According to different industrial scenes, the positioning accuracy of the vision system can reach 0.1 mm to 20 µm in 0.8 s.

Exploring the effects of knowledge of writing on reading Chinese characters in skilled readers.

Knowledge about how characters are written has been argued to play a particularly important role in how children learn to read Chinese. In the current study, we investigate the role that knowledge about writing characters plays in visual word processing in skilled adult readers. While there is clear neuropsychological evidence against the strong version of the hypothesis that reading depends on writing in Chinese even once literacy is acquired, it is still possible that writing could have a modulatory influence on how visually presented Chinese characters are processed in literate readers. The present study addressed this hypothesis using a visual same/different judgment task on pairs of characters that vary in how similar the 2 characters are visually and how similar they are in terms of motor plan, using 24 expert readers and writers of Chinese and 24 naïve participants with no prior experience with written Chinese as subjects. The results of linear mixed-effects modeling indicate that the speed of same/different judgments is influenced by visual similarity, but not by how similar they are written, even in the group of skilled readers. These results suggest that knowledge of how Chinese characters are written does not influence visual character processing in skilled readers.

Processing Homophones Interactively: Evidence from eye-movement data.

The question of how to process an ambiguous word in context has been long-studied in psycholinguistics and the present study examined this question further by investigating the spoken word recognition processes of Cantonese homophones (a common type of ambiguous word) in context. Sixty native Cantonese listeners were recruited to participate in an eye-tracking experiment. Listeners were instructed to listen carefully to a sentence ending with a Cantonese homophone and then look at different visual probes (either Chinese characters or line-drawing pictures) presented on the computer screen simultaneously. Two findings were observed. First, the results revealed that sentence context exerted an early effect on homophone processes. Second, visual probes that serve as phonological competitors only had a weak effect on the spoken word recognition processes. Consistent with previous studies, the patterns of eye-movement results appeared to support an interactive processing approach in homophone recognition.

Context Effects and Spoken Word Recognition of Chinese: An Eye-Tracking Study.

This study examined the time-course of context effects on spoken word recognition during Chinese sentence processing. We recruited 60 native Mandarin listeners to participate in an eye-tracking experiment. In this eye-tracking experiment, listeners were told to listen to a sentence carefully, which ended with a Chinese homophone, and look at different visual probes (Chinese characters or different line-drawing pictures) presented concurrently on the computer screen naturally. Different types of context and probe types were manipulated in the experiment. The results showed that (1) preceding sentence context had an early effect on spoken word recognition processes and (2) phonological information of the distracters had only a negligible effect on the spoken word recognition processes. Finally, the patterns of eye-tracking results seemed to favor an interactive approach in spoken word recognition.
