Abstract:

Age-related declines for many sensory and cognitive abilities are greater for males than for females. The primary purpose of the present investigation was to consider whether age-related changes in lipreading abilities are similar for men and women by comparing the lipreading abilities of separate groups of younger and older adults. Older females, older males, younger females and younger males completed vision-only speech recognition tests of: (1) 13 consonants in a vocalic /i/-C-/i/ environment; (2) words in a carrier phrase; and (3) meaningful sentences. In addition to percent correct performance, consonant data were analyzed for performance within viseme categories. The results suggest that while older adults do not lipread as well as younger adults, the difference between older and younger participants was comparable across gender. We also found no differences in the lipreading abilities of males and females, regardless of stimulus type (i.e., consonants, words, sentences), a finding that differs from some reports by previous investigators (e.g., Dancer, Krain, Thompson, Davis, & Glenn, 1994).

El deterioro relacionado con la edad de muchas habilidades sensoriales y cognitivas es mayor para los hombres que para las mujeres. El propósito primario de la presente investigación fue considerar si los cambios relacionados con la edad en la habilidad de leer los labios eran similares para hombre y mujeres, comparando las habilidades de lectura labial de grupos separados de adultos jóvenes y viejos. Mujeres viejas, hombres viejos, mujeres jóvenes y hombres jóvenes completaron pruebas de reconocimiento del lenguaje únicamente por medio de la visión de: (1) 13 consonantes en un ambiente vocálico /i/-C-/i/; (2) de palabras en una frase portadora; y (3) de frases significativas. Además del porcentaje correcto de desempeño, los datos de las consonantes se analizaron en cuanto a desempeño dentro de las categorías de visemas. Los resultados sugieren que mientras los adultos más viejos no leen los labios tan bien como los adultos más jóvenes, las diferencias entre participantes más viejos y más jóvenes fueron comparables entre los géneros. Tampoco encontramos diferencias en las habilidades de lectura labial de hombres y mujeres, sin importar el tipo de estímulo (p.e., consonantes, palabras, frases), un hallazgo que difiere con algunos reportes de investigadores previos (p.e., Dancer, Krain, Thompson, Davis, & Glenn, 1994).
