A comparison of the expression of simultaneity in Thai and English adults and children using short animations

The aim of the present study was to investigate the linguistic devices that Thai and English children aged 4 years, 5 years, 6 years, 7 years and adults use to express simultaneous or overlapping temporal relations depicted in short animations. Thai has imperfective aspectual morphemes but they are not morphologically grammaticalised on the verb and usage in general is optional and not obligatory. These particular aspectual characteristics of Thai form an interesting comparison with English, which has obligatory grammaticised aspectual marking on the verb. An additional aim is to investigate if these grammatical differences and degrees of obligatoriness of aspectual marking in English and Thai affect what particular aspects of the external simultaneous events depicted in the animations are expressed, and if so, do children and adults show the same language-specific patterns
