In addition, this study addressed whether the acoustic similarity between lexical tones could have any effects on perceptual development. Through the international collaboration with a world-leading infant study laboratory at the University of Washington, we have established the infant speech perception laboratory during the first project year. We also collected the infant data for the Experiment 1 that was designed to test the age effect on tone perception. The perceptual change of 7- and 11-month-old Mandarin-learning infants discriminating lexical tones was examined by utilizing a Mandarin Tone 1 vs. Tone 3 contrast. The results of the older infant group demonstrated that this tone contrast was not difficult for this age group to discriminate (mean percent correct = 80.49%) and no significant gender difference on perceiving this tone contrast was obtained for the 10-12 month-old Mandarin-learning infants. In addition to testing younger infants on the same tone contrast, the on-going project will use various tone contrasts to examine the tone perception development in the following second project year.application/pdf157530 bytesapplication/pdfzh-TW國立臺灣大學心理學系暨研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9748/1/932413H002028.pdf
