A Study on the Cognitive Process of Isolating Language for Developing Software User Interface

This research focuses on the cognitive process in Thai language because the 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, which sometimes leads to ambiguity. This research studies the cognitive processing and influence of final consonants and non-final consonants by using word identification tasks to verify the differences in time spent to answer and correct data consisting of 4 main variables: Types of question divided by single words and sentences; Types of option word or word choices divided by words with consonants and without consonants. The level of difficulty was divided into 3 levels: easy, middle, and hard, while the Type of word was divided into 4 types: Uncontrolled, Homophone, Homograph, and Semantic. The differences of average duration for identifying target 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. It works as the accelerator of competency in cognition of Thai language and helps learners to receive more precise and faster information.
