Abstract

Abstract

The present study examined the relationship between dichotic speech recognition and state anxiety. State anxiety, as determined by the State-Trait anxiety inventory (STAI), was measured pre- and post-dichotic testing in a group of young adults with normal hearing. Dichotic speech recognition was measured for three types of speech stimuli: 3-pair digits, monosyllabic words, and consonant-vowels. Results revealed significant increases in state anxiety as a function of dichotic testing for all stimulus types. There was not a significant difference, however, in state anxiety between the stimulus types. A subset of subjects (n=44) repeated the experiment a second time. There were no significant differences in state anxiety experienced due to dichotic listening between the two sessions. Results from the present study confirm that dichotic listening induces significant increases in state anxiety in a group of young adults with normal hearing. Although statistically significant, the mean increase in state anxiety does not exceed normative levels for college students. Further, the effect of anxiety on dichotic speech recognition performance appears minimal in this population.

Sumario

El presente estudio examinó la relación entre el reconocimiento dicótico del lenguaje y los estados de ansiedad. El estado de ansiedad, determinado por el inventario estatal de rasgos de ansiedad (STAI), fue medido antes y después de las pruebas dicóticas en un grupo de adultos jóvenes con audición normal. El reconocimiento dicótico del lenguaje fue medido con tres tipos de estímulos lingüísticos: dígitos en 3 pares, monosilábicos dicóticos, y vocalesconsonantes. Los resultados revelaron aumentos significativos en el estado de ansiedad como una función de la evaluación dicóticos para todos los tipos de estímulos. No existió una diferencia significativa , sin embargo, en el estado de ansiedad entre los tipos de estímulos. Un subgrupo de sujetos (n = 44) repitió el experimento una segunda vez. No hubo diferencias significativas en el estado de ansiedad experimentado debido a la audición dicótica entre las dos sesiones. Los resultados del presente estudio confirman que la audición dicótica induce aumentos significativos en el estado de ansiedad en un grupo de adultos jóvenes con audición normal. Aunque resulte estadísticamente significativo, la media del incremento en el estado de ansiedad no excede los valores normativos para estudiantes universitarios. Más aún, el efecto de la ansiedad sobre el desempeño en el reconocimiento dicótico del lenguaje parece mínimo en esta población.
