Visual plots depicting the relationship between L2 prosodic proficiency and auditory processing at the beginning (T1, left panel) and end (T2, right panel) of the project. Word stress production is represented by green dots and intonation production by yellow dots. The lines represent linear trendlines, with shaded regions indicating the 95% confidence intervals. Higher prosodic proficiency scores indicate more advanced proficiency, while lower auditory processing scores signify more precise pitch discrimination. At T1, the role of auditory processing in L2 prosodic proficiency remained nonsignificant. At T2, participants with more precise auditory processing demonstrated significantly more advanced L2 prosodic proficiency.
