Research Lab



Screen Shot 2022-03-23 at 22.38.03

Our psycholingusitic lab started to operate on September 28th, 2017. It is currently located at Integrated Research Bldg. for Humanities & Social Sciences, Room 711.

We are studying language in the mind, using various experimental techniques. From time to time, we also make sure to remind ourselves of what our academic and life goals truly are. We educate ourselves on honest research conducts to avoid questionable, not to mention unethical, research practices.

The language of instruction, communication, and research is mostly English.  


Everything students need to know

Sadly, it is not uncommon to see students analyzing data a month before the deadline (and consequently writing the thesis the day before the deadline). It takes time to design a study. It takes time to collect data. It takes time to analyze data. Of course, it takes even more time to write a thesis. Whatever you do, it takes more time than you think. Please understand 10 steps in completing your thesis:

Metaphor comprehension processing in L1 and L2 


Metaphor・Figurative Language・Psycholinguistics


"Babies are angels" means a lot more than "Babies are cute". The use of metaphor enriches our imagination and helps us understand abstract features.Thus, metaphors are used not only for jokes and humor in literature, but also for  summarizing, exemplifying, describing and clarifying in academic contexts. My academic goal is to discover how metaphors are understood in L1 and L2. If you are interested in this topic  (and our lab also), don't hesitate to let me know.

Conceptualisation of Event Roles in Japanese-English Bilinguals


Event Representations, Bilinguals


I am mesmerised by linguistic relativity which studies how language influences thought and world view of its speakers. The research on this topic has been century-old and many studies have found the robust evidence of language effects on thoughts. It becomes more interesting when we approach this issue from the perspective of bilinguals. Does learning a new language change the way we think? If it does, to what extent and in what domains does it happen? I take an experimental approach to these questions. If you find this research topic fascinating as well, please feel free to contact me.

Research project



Language Processing, Mental Lexicon, Word Recognition


The processing of language in the brain is a very interesting phenomenon. It seems like the human brain is a supercomputer that is able to store and process an infinite amount of linguistic information in a few milliseconds, and it becomes even more fascinating if one can speak more than one language. As a speaker of 4 languages (Japanese, English, Persian, and Turkish), I am interested in understanding how this phenomenon takes place in the brain, and finding out if there is a special structure in the brain to accommodate for all these languages.
