目的：本研究旨在验证语义表征深度对幼儿词汇提取的影响。在实验条件下，手势引起对物体形状（SHP）或功能（FNC）的注意。没有语义线索下提供的控制条件（CrL）。单词学习条件发生在3天的每一天。在第4天，在3个水平的支架（无线索图片命名，线索图片命名，图片识别）上评估单词提取。语义表征的证据提供了在快速和缓慢的映射intervention.Results：较少的脚手架是必要的词检索（无线索和线索命名）在实验条件下比在CTL条件下。然而，更多的SHP比FNC条件的目标被检索到的无线索图片命名。后一种差异可能与SHP条件下目标的上级快速映射有关。幼儿陈述的目标功能（慢映射）在实验条件下，但这是上级CTL条件performance.Conclusions：词检索是一个连续的行为，是积极的影响，语义表征。物体的语义知识可以通过形状或功能手势来丰富，从而提高幼儿的物体词产生。形状线索似乎更有效地达到这一目的。
Purpose: This study tested the hypothesis that depth of semantic representation influences toddlers' word retrieval.Method: Nineteen toddlers participated under 3 word learning conditions in this longitudinal study. Gestures cued attention to object shape (SHP) or function (FNC) in the experimental conditions. No semantic cue was provided under a control condition (CrL). Word learning conditions occurred on each of 3 days. On the 4th day, word retrieval was assessed across 3 levels of scaffolding (uncued picture naming, cued picture naming, picture recognition). Evidence of semantic representation was provided at fast and slow mapping intervals.Results: Less scaffolding was necessary for word retrieval (uncued and cued naming) under experimental conditions than under the CTL condition. However, more SHP than FNC condition targets were retrieved for uncued picture naming. This latter difference may be related to the superior fast mapping of targets under the SHP condition. Toddlers stated object functions (slow mapping) comparably in the experimental conditions, but this was superior to CTL condition performance.Conclusions: Word retrieval is a continuous behavior that is positively influenced by semantic representation. Semantic knowledge of objects can be enriched by shape or function gestures, thereby improving toddlers' object word productions. Shape cues appear to be more effective for this purpose.
