Abstract
[Resumen] El objetivo de este experimento era estudiar
si los estímulos neutros reciben procesamiento
automático cuando son presentados eficazmente
enmascarados en un paradigma de priming.
Los primes consistían en las letras "o", "e", o
"u". Las mismas letras "o" y "e" fueron utilizadas
como target, dando lugar a tres condiciones
de enmascaramiento, cada una de ellas con
dos combinaciones prime/target (congruente:
e/e y %; incongruente: o/e y e/o; neutra: u/e y
u/o). Además, el target fue considerado como
un estímulo imperativo para una tarea de tiempo
de reacción (TR). Treinta y seis sujetos fueron
expuestos a 20 ensayos de cada condición
de enmascaramiento con una asincronía del
estímulos de 23 milisegundos. Los resultados
demuestran que la presentación eficazmente
enmascarada de un estímulo neutro produce
facilitación o interferencia con la tarea de TR,
dependiendo de si el target es un estímulo congruente
o incongruente con el prime.
[Abstract] Sensitivity of a reaction time task to automatic processing of neutral masked stimu1i The purpose of this experiment was to study if the neutral stimuli receive automatic processing when presented effective1y masked in a priming paradigm. The primes consisted of the "o", "e", or "u" 1etters. The same "o" and "e" 1etters were used as target, giving three masking conditions, each with two prime/target combinations (congruent -e/e and 0/0-; incongruent -o/e and e/o-; neutral -u/e and u/o-). Furthennore, the target was considered an imperative stimu1us for a reaction time (RT) task. Thirty-six subjects were exposed to 20 tria1s of each masking conditions with a stimu1us- onset asynchrony of 23 milliseconds. The results demonstrate that an effective masking presentation of a neutral stimulus produces either facilitation or interference with the RT task, depending on whether the target is a congruent or an incongruent stimu1us with the prime
