Summary: | The main goal of this research has been to elucidate the role played by words morphological
structure in the organization of the internal lexicon and, consequently, in the strategies used to access
word mental representations. Three experiments were performed, based on a lexical decision task and
on the use of a word priming technique. Response latencies for word/nonword classification were
measured. Experiments 1 and 2 used visual stimuli, where as experiment 3 used auditory stimuli.
Results obtained under both perceptual modalities show, the same pattern: 1) there is a facilitatory
effect in recognition (lower RTs) either in the repetition condition or with a previous presentation of a
morphologically related word: 2) the repetition effect is, in any event, higher than the facilitatory
effect due to rnorphological relation; 3) within the facilitation by morphological relation, there are not
significant differences botween the base for priming over the derived form and the priming of the
latter over the former. These result seem to support an abstract code of representation which includes
under the sarne lexical entry a whole family of morphologically related words. Even in the case of
separated lexical entries for each particular form, some other mechanism ought to be postulated in
order to account for the role played by morphological information in the general organization of the
internal lexicon.
El objetivo principal de esta investigación es el de contribuir a un mayor conocimiento del
papel que desempeña la estructura morfológica de las palabras en la organización del léxico interno y,
por consiguiente, en las estrategias que emplean los sujetos para acceder a la representación mental de
las palabras. Se han realizado tres experimentos, basados en una tarea de decisión léxica y en la
utilización de la técnica de priming o presentación previa de un supuesto elemento facilitador del
reconocimiento de cada estímulo. Se midió la latencia de respuesta para clasificar los estímulos como
palabras o no-palabras del idioma. Los dos primeros experimentos se efectuaron bajo la modalidad
visual de reconocimiento y el tercero bajo la modalidad auditiva. Los resultados obtenidos bajo las dos
modalidades perceptivas son coincidentes y ponen de manifiesto.que: 1) se da un efecto de facilitación
en el reconocimiento, tanto al presentar una palabra precedida por sí misma (repetición) como al
presentarla precedida por otra relacionada morfológicamente; 2) el efecto de |
