Abstract
Un tema clave en psicología cognitiva se centra en cómo el reconocimiento de una palabra-test resulta influido por otras palabras ortográficamente similares (“palabras
vecinas”). En este estudio se manipuló el número de vecinos de las palabras-test, utilizando la técnica de “priming enmascarado” (Forster y Davis, 1984), con una tarea
de decisión léxica y una asincronía estimular señal-test de 33 ms. El objetivo fue analizar si la magnitud de los efectos de “priming” ortográfico (v.g., tigus-TIFUS) y de repetición
(tifus-TIFUS) se ve modulada por el número de vecinos de las palabras-test. Dada la breve asincronía estimular señal-test utilizada se adoptó una metodología psicofísica
(con pocos participantes, pero bien entrenados). Los modelos activacionales predicen una interacción entre “priming” ortográfico (y de repetición) y el número de vecinos,
mientras que el modelo de búsqueda serial de Forster (1987; Forster y Davis, 1984) predice una interacción del número de vecinos con el “priming” ortográfico, pero no
con el “priming” de repetición. Los resultados muestran una interacción de la densidad de vecindad tanto con el “priming” ortográfico como con el de repetición, lo cual
resulta más consistente con los modelos activacionales. Finalmente, se examinaron las posibilidades de emplear una metodología psicofísica con la técnica de “priming enmascarado”.
One of the most central issues in cognitive psychology is how the processing of a given word is affected by its similarly spelled words (the so-called “orthographic neighbors”). In the present study, we analyzed how the magnitude of orthographic/repetition priming (e.g., tigus-TIFUS and tifus-TIFUS) is modulated by the number of neighbors of a target word. We used the masked priming technique (Forster & Davis, 1984) at a 33 ms stimulusonset asynchrony (SOA) in the lexical decision task. Be-cause of the very brief SOA, a psychophysical methodol-ogy (i.e., few but well-trained participants) was adopted. Activation-based models predict greater ortho-graphic/repetition effects for the words with few neighbors, whereas the entry-opening model (Forster & Davis, 1984) predicts an interaction between number of neighbors and orthographic (but not repetition) priming. The results show greater repetition/orthographic priming effects for hermit words than for words with many neighbors, which is consistent with an activation account. Finally, we examine the advantages of using a psychophysical methodology combined with the masked priming technique.
