The Effect of Final Consonants in the Cognitive Process of Thai Language

Written nature of Thai language does not have spaces in a sentence like English and does not have Kanji characters as in Japanese. Words will be written continuously until the end of the sentence the judgement for separate words depends on human decisions. Therefore, cognitive processing is very important to separate words in the Thai language. This research studied the cognitive processing and influence of final consonants in the Thai language by using word identification tasks to verify the difference in time spent answering and correcting data, as there is no direct measurement. Therefore, the time spent on selected word and correctness ratio was the most important variable in the cognitive processing test. The differences of average duration for selected words were analyzed by ANOVA and t-test that is statistical analysis. The results showed that final consonants work as the space in English is used for separating words and sentences and can make the Thai language easier for detect words in Thai language and also reduce the confusion when separating words in the long run on sentences. It works as the accelerator of competency in cognition of Thai language and helps learners to receive more precise and faster information.
