标志性是遍布许多标志语言（包括美国手语（ASL））的词典的属性。标志性的标志在其含义的符号形式之间表现出动机的非保证映射。我们研究了标志性是否增强了ASL的语义启动效应，以及是否比非偶像迹象更快地识别标志性符号（控制标志性，语义相关性，熟悉性和可像性的强度）。二十个聋人签名者对主要目标对的第二项做出了词汇决定。标志性的目标符号先于（a）标志性和语义相关的主要符号，（b）非偶像和语义相关，或（c）语义无关。此外，在语义上无关的素数之前，一组非偶像目标符号。当目标符号在语义上相关的素数之前，观察到目标符号的显着促进。但是，标志性并没有增加启动效果（例如，目标标志钢琴是由标志性的标志吉他和非偶像符号音乐平等启动的）。另外，与非偶像符号相比，标志性符号未更快或更准确地识别。这些结果证实了手语的语义启动的存在，并暗示标志性在在线词汇处理中不起作用。
Iconicity is a property that pervades the lexicon of many sign languages, including American Sign Language (ASL). Iconic signs exhibit a motivated, nonarbitrary mapping between the form of the sign ant its meaning. We investigated whether iconicity enhances semantic priming effects for ASL and whether iconic signs are recognized more quickly than noniconic signs are (controlling for strength of iconicity, semantic relatedness, familiarity, and imageability). Twenty deaf signers made lexical decisions to the 2nd item of a prime target pair. Iconic target signs were preceded by prime signs that were (a) iconic and semantically related, (b) noniconic and semantically related, or (c) semantically unrelated. In addition, a set of noniconic target signs was preceded by semantically unrelated primes. Significant facilitation was observed for target signs when they were preceded by semantically related primes. However, iconicity did not increase the priming effect (e.g., the target sign PIANO was primed equally by the iconic sign GUITAR and the noniconic sign MUSIC). In addition, iconic signs were not recognized faster or more accurately than were noniconic signs. These results confirm the existence of semantic priming for sign language and suggest that iconicity does not play a robust role in online lexical processing.
