要約(日本語): Language is essential to every aspect and interaction in everyday lives. Strong language skills are assets that will promote a lifetime of effective communication. In communication, language can be interpreted differently depending on emotional context. Therefore, language learning is important to sharpen cognitive and life skills. One of techniques to learn a new language is shadowing. Shadowing is an advanced learning technique - listening to a text in the target language and then speaking it aloud at the same time with a native speaker, even if we do not understand a word of it. It is basically learning another language in a way that is similar to how we learn our first language - repeating sounds exactly as we hear them. There have been many studies on the emotional contexts and language processing. Most studies have found that the result of the mood induction is a change in the performance of cognitive tasks. The objective of this research is to determine whether sentences with emotions can affect the language area in the brain for language learning. In this study, the authors conducted an experiment and twenty seven Japanese subjects participated in the experiments. Malay language was used because it is a new language to the Japanese subjects. A near-infrared spectroscopy (NIRS) system was used for the experiments to observe the brain activity of each subject. Spectroscopic measurements have been performed by using NIRS in order to obtain the relative concentration of the oxygenated hemoglobin (Hb), deoxygenated Hb, and its total Hb. A survey was conducted to validate Malay sentences with emotions before the NIRS measurement experiment. Twenty-seven Japanese students participated in the experiment. In this study, relative changes of blood Hb concentration in the brain were observed by using NIRS to see the brain function activities of each subject when he/she was listening to the sentences with and without emotions. The results of the experiment showed that the Hb concentration changes of the subjects’ brain for Malay sentences with emotions were higher than those without emotions on average. In particular, the front polar region of the brain, which roughly corresponds to Brodmann Area (BA) 10, also tended to experience a higher level of changes in Hb concentration while listening to Malay language with emotions. The results of the experiment in this study showed less activation of the language area in the brain while listening to the emotional context. This suggests that subject’s brain gave too much attention to the emotions rather than to the language itself. BA 10, which relates to working memory, was also activated when listening to the sentences with emotions. These results indicate that sentences with emotions have an impact on working memory and emotional sentences may not be suitable for language learning. On the other hand, they suggest that emotional sentences can affect the working memory, and thus emotional contents of stimuli modulates can enhance working memory processes, which are known to be essential to language learning.
