The effects of visual complexity for Japanese kanji processing with high and low frequencies
نویسندگان
چکیده
The present study investigated the effects of visual complexity for kanji processing by selecting target kanji from different stroke ranges of visually simple (2–6 strokes), medium (8–12 strokes), and complex (14–20 strokes) kanji with high and low frequencies. A kanji lexical decision task in Experiment 1 and a kanji naming task in Experiment 2 were administered to native Japanese speakers. Results of both experiments showed that visual complexity inhibited the processing of lowfrequency kanji, whereas such consistent, inhibitory effects of visual complexity were not observed in the processing of high-frequency kanji. Kanji with medium complexity were processed faster than simple and complex kanji in high frequency.

Logographic Kanji versus phonographic Kana in literacy acquisition: how important are visual and phonological skills?
It is well-established that phonological skills are important for literacy acquisition in all scripts. However, the role of visual skills is less well understood. For logographic scripts in which a symbol represents a whole word or a meaningful unit, the importance of visual memory in literacy acquisition might be expected to be high because of the visual complexity of logographic characters, b...
متن کاملNeural basis of hierarchical visual form processing of Japanese Kanji characters
INTRODUCTION We investigated the neural processing of reading Japanese Kanji characters, which involves unique hierarchical visual processing, including the recognition of visual components specific to Kanji, such as "radicals." METHODS We performed functional MRI to measure brain activity in response to hierarchical visual stimuli containing (1) real Kanji characters (complete structure with...
متن کاملA cross-linguistic evaluation of script-specific effects on fMRI lateralization in late second language readers
Behavioral and neuroimaging studies have provided evidence that reading is strongly left lateralized, and the degree of this pattern of functional lateralization can be indicative of reading competence. However, it remains unclear whether functional lateralization differs between the first (L1) and second (L2) languages in bilingual L2 readers. This question is particularly important when the p...
متن کاملAn fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli
ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...
متن کاملDissociating Congruence Effect in Letters versus Shapes: the Case of Kanji and Kana in Japanese
Alphabet letters and non-letter shapes are dissociated at the early visual processing stage, which was demonstrated by positive congruence effect for non-letters and negative congruence effect for letters. The present study reviewed attempts extending those findings into other orthographic system, kanji and kana in Japanese. Letters and pseudo-letters were targets in a choice-response task. Tar...
