RT Journal Article T1 Morphological effects in word identification: tracking the developmental trajectory of derivational suffixes in Spanish A1 Lázaro López-Villaseñor, Miguel A1 Illera, Víctor A1 Acha, Joana A1 Escalonilla, Ainoa A1 García, Seila A1 Sainz Sánchez, Francisco Javier AB The role of morphological processing has been shown to be highly relevant in learning to read. However, there is little evidence on the processing ofderivational suffixes from a developmental perspective. The aim of this study is to assess the developmental emergence of suffixes as meaningful processing units inword recognition. To that aim, 96 children from fourth, fifth and sixth grade, as well as adults, took part in a masked priming lexical decision task (go/no-go version).Complex and simple words were primed by other words sharing the suffix (as in lechero/milkman/-[ jornalero/laborer/) and word ending (as in araña/spider/-[España/Spain/) or by words not sharing an ending (surfista/surfer/-[jornalero/ laborer/; carpeta/folder/-[España/Spain/). Results in adults replicate previousstudies by showing that only the related condition of complex words elicits a significant facilitation (see Dun˜abeitia, Perea, & Carreiras, 2008). With respect tochildren, only sixth graders generated a similar pattern to adults. Children in fourth and fifth grade showed no morphological effect.
