The present survey was conducted to examine the development of syntactic comprehension in neurotypical children. Prior to the main survey, a preliminary survey was conducted involving 45 children aged between 3 and 10 years old to determine sentence patterns and the frequencies for which the tasks should be implemented. The subjects were 125 neurotypical infants aged 3 ‒ 6 years old. Eight syntactic tasks （involving comparative, causative, and passive sentences, as well as those expressing the acts of giving and receiving） were prepared, and a correct response rate of 60% for each age group was deﬁned as the passing point for each task. Correlations among each of the eight syntactic tasks, the Test for Delayed Language Development Based on Sign-Signiﬁcant Relations （S-S test）, the Picture Vocabulary Test ‒ Revised （PVT-R）, and short version of the Question-Answer Interaction Test were examined. The correct response rates increased with age in all of the tasks. Infants in all age groups did not have satisfactory skill levels to understand causative sentences, and those associated with the acts of giving and receiving. Correlations were observed between the tasks in the present test and the PVT-R and short version of the Question-Answer Interaction Test. The results suggested that syntactic comprehension is associated with the development of vocabulary comprehension.
