Abstract

This study investigates whether threat-related words are especially likely to be perceived in unattended locations of the visual field. Threat-related, positive, and neutral words were presented at fixation as probes in a lexical decision task. The probe word was preceded by 2 simultaneous prime words (1 foveal, i.e., at fixation; 1 parafoveal, i.e., 2.2 deg. of visual angle from fixation), which were presented for 150 ms, one of which was either identical or unrelated to the probe. Results showed significant facilitation in lexical response times only for the probe threat words when primed parafoveally by an identical word presented in the right visual field. We conclude that threat-related words have privileged access to processing outside the focus of attention. This reveals a cognitive bias in the preferential, parallel processing of information that is important for adaptation.

En el presente estudio se investiga si las palabras relativas a peligros se perciben fuera del campo de atención visual. En una tarea de decisión léxica se presentaron como estímulos de prueba palabras representativas de peligro, otras de contenido emocional positivo, y otras neutras. La palabra de prueba iba precedida por 2 palabras-contexto simultáneas (1 en posición foveal, en el centro del campo visual; 1 parafoveal, desplazada 2.2 grados a izquierda o derecha) durante 150 ms. Una de las palabras-contexto era idéntica a la de prueba o bien no estaba relacionada ésta. Los resultados mostraron facilitación en la tarea de decisión léxica para las palabras de peligro cuando estaban precedidas por una palabra idéntica en el campo parafoveal derecho. Se concluye que las palabras de peligro tienen un acceso privilegiado (en comparación con las neutras y con las positivas) para ser analizadas fuera del foco de atención. Esto revela un sesgo cognitivo en el procesamiento preferente y en paralelo de la información con importancia adaptativa.
