Atención y nicotina

Abstract

El principal objetivo de esta investigación fue evaluar el efecto del consumo de nicotina y su abstinencia sobre procesos atencionales, utilizando la prueba de evaluación "Attentional Networks Task" (ANT). Participaron en el estudio 67 estudiantes de Psicología en las siguientes condiciones: (1) Sujetos fumadores, (2) sujetos fumadores en abstinencia y (3) sujetos no fumadores. Los resultados arrojaron diferencias entre los grupos solo en la variable orientación, donde los grupos de las condiciones control y con abstinencia se beneficiaron más de las claves espaciales para resolver la tarea, obteniendo valores superiores en esta variable. Con respecto al tiempo de reacción hallamos diferencias significativas entre grupo abstinente y grupo sin abstinencia, mostrando este último menor tiempo de reacción. Los resultados hallados en este trabajo se discuten en relación con estudios similares, sugiriendo que una interrupción del consumo habitual de nicotina y la correspondiente abstinencia pueden interferir en el funcionamiento de la atención.

The main objective of this research was to evaluate the effect of nicotine and nicotine withdrawal on attentional processes, using the Assessment Test "Attentional Networks Task" (ANT). Sixty seven students participated in the study under the following conditions: (1) Smokers subjects; (2) Smokers subjects under abstinence; and (3) non-smoking subjects. The results showed differences among the groups only in the orientation variable, in which the control and abstinence groups improved their performance when spatial cues were presented, showing higher orientation scores. With respect to the reaction time, significant differences were found between abstinent group and group without abstinence, the latter showing lower reaction time. Present results are discussed with respect to previous studies, suggesting that a disruption of regular consumption of nicotine can interfere with attention function.
