| Outline of Research at the Start |
This project examines how kanji and kana are processed. Particularly, whether kanji and kana both evoke lexical items to the same extent (e.g. do 犬 and いぬ equally evoke “dog” in the Japanese mind?). This project uses behavioral and brain experiments to discover the precise answer to this question.

| Outline of Annual Research Achievements |
One paper is published (2021) in the Memory & Cognition Journal. In this paper we manipulated the script type of Japanese distractor words in the phonological Stroop task (see Verdonschot & Kinoshita, 2018). We found that color-naming responses were faster when the initial phoneme was shared between the color name + romaji distractor than when the initial phoneme was different, thereby showing a phoneme-based phonological Stroop effect. Next, in collaboration with Prof. Miyaoka we have begun recording EEG using a picture naming task with different script as distractors (kanji vs hiragana). Unfortunately, these experiments had to be put on hold due to the COVID outbreak.
