Abstract
To follow up children who required attention in health examination when they were 18 months, the authors provide developmental counseling services for parents who have children aged 24 months in Sakaide, Kagawa Prefecture. The purpose of this present study is to produce a vocabulary checklist that can be used for screening in counseling. Therefore, we carried out a questionnaire survey to clarify the vocabulary development in 2 years old. The subjects of the survey were 161 parents who have children were 23-35 months and belong to 12 nursery schools in Sakaide. In the survey, we used a checklist as a questionnaire including 452 words; nouns, pronouns, abstract words, verbs, adjectives, adjective verbs, adverbs, and interjections. This present study focused on abstract words and pronouns. In discussion, we discussed about abstract words and pronouns that children tended to have been acquired between 24 and 30 months. At first, the abstract words were“simple concepts about number, color, space, and time”, “concepts allowing visual comprehension”, and “cenesthetic abstract concepts”. Second, the pronouns were“demonstrative pronouns associated with [ko] ”, and“demonstrative pronouns associated with [a]”; [ko] is the Japanese that means [this] and these indicate objects in the domain of the self and parents, and [a] which indicate objects in the domain of the third person is [that] . Next, the words that had been acquired only by less than 60% of children aged even 34-35 months were“abstract words associated with invisible phenomena and psychological states”and“highly abstract concepts about position and direction”, “demonstrative pronouns associated with [so] that indicate objects present between the self and parents”, and“sets of persons including the self”. These are difficult for 2-year-old children to understand.
