Studies have demonstrated a morphological decomposition process in the initial stages of visual word recognition based on orthographically defined morphemes and independent of semantic and lexical information. The present study sought to investigate this phenomenon in adult Brazilian Portuguese-speaking readers.
Participants performed a lexical decision task preceded by primes at two Stimulus Onset Asynchrony (SOA): 33 or 250 ms. The primes had one of the following relations with the target word: morphological (porteiro [DOORKEEPER]-PORTA [DOOR]), morpho-orthographic (cordeiro [LAMB]-CORDA [ROPE]), orthographic (abril [APRIL]-ABRIU [OPENED]), semantic (abelha [BEE]-MEL [HONEY]), or no relation (pessoa [PERSON]-DADO [DICE]).
Priming effects were observed for the morphological and semantic conditions at both SOAs but not for the orthographic and morpho-orthographic conditions.
Our results suggest that semantic representations mediate morphological priming in Brazilian Portuguese since the early stages of visual word recognition.
研究表明，在视觉单词识别的初始阶段，存在一个基于正字法定义的语素且独立于语义和词汇信息的形态分解过程。本研究旨在调查成年巴西葡萄牙语读者中的这一现象。
参与者在两种刺激起始异步（SOA）条件下进行词汇判断任务，SOA分别为33毫秒或250毫秒。启动刺激与目标词具有以下关系之一：形态关系（porteiro[看门人]-PORTA[门]）、形态正字法关系（cordeiro[羔羊]-CORDA[绳子]）、正字法关系（abril[四月]-ABRIU[打开]）、语义关系（abelha[蜜蜂]-MEL[蜂蜜]）或无关系（pessoa[人]-DADO[骰子]）。
在两种SOA条件下，均观察到形态和语义条件下的启动效应，但正字法和形态正字法条件下未观察到。
我们的结果表明，自视觉单词识别的早期阶段起，语义表征就在巴西葡萄牙语中介导形态启动。
