To investigate the influence of sign phonology and iconicity during sign processing in deaf children, the roles of these sign features were examined using an experimental sign-picture verification paradigm. Participants had to make decisions about sign-picture pairs, manipulated according to phonological sign features (i.e., hand shape, movement, and location) and iconic sign features (i.e., transparent depiction of meaning or not). We found that phonologically related sign pairs resulted in relatively longer response latencies and more errors whereas iconic sign pairs resulted in relatively shorter response latencies and fewer errors. The results showed that competing lexical sign candidates (neighbor signs) were activated during sign processing by deaf children. In addition, deaf children exploit the iconicity of signs during sign recognition.
为了研究聋童在手势处理过程中手势语音学和象似性的影响，使用实验性的手势-图片验证范式来检验这些手势特征的作用。参与者必须对手势-图片对做出判断，这些对根据手势语音特征（即手型、动作和位置）和象似手势特征（即是否透明地描绘意义）进行操纵。我们发现，语音相关的手势对导致相对较长的反应潜伏期和更多错误，而象似手势对导致相对较短的反应潜伏期和更少错误。结果表明，在聋童的手势处理过程中，相互竞争的词汇性手势候选（相邻手势）被激活。此外，聋童在手势识别过程中利用了手势的象似性。
