This study investigates whether (a) Cantonese and (b) English listeners integrally or independently perceive Thai tone and segmental information. Listeners completed a modified AX discrimination task that contained a control block (without segmental variation) and an orthogonal block (with segmental variation). Relative to their own performance in the control block, the Cantonese listeners showed increased response time, decreased proportion of accuracy, and decreased sensitivity index in the orthogonal block. By contrast, the English listeners showed similar response time, proportion of accuracy, and sensitivity index across the two blocks. These reflect integral processing among the Cantonese but not the English listeners. This finding motivates the dimensional transfer hypothesis. The hypothesis posits that L1 perceptual experience shapes the perceptual integrality (or nonintegrality) of foreign suprasegmental and segmental information.

外来片段和音调信息的感知完整性:维度转移假设
本研究调查 (a) 粤语和 (b) 英语听众是否整体或独立地感知泰语语调和片段信息。听众完成了修改后的 AX 辨别任务,其中包含控制块(无分段变化)和正交块(有分段变化)。相对于他们自己在控制块中的表现,粤语听众在正交块中表现出响应时间增加、准确性比例下降以及灵敏度指数下降。相比之下,英语听众在两个区块中表现出相似的响应时间、准确性比例和敏感度指数。这些反映了粤语听众的整体加工过程,而不是英语听众的整体加工过程。这一发现激发了维度转移假说。该假设假设 L1 感知体验塑造了外来超分段和分段信息的感知完整性(或非完整性)。
