✦ Synopsis


This study investigated vocal and facial expression matching in 24 10-month-old infants. Half of the mothers had reported depressive symptoms [i.e., elevated scores on the Center for Epidemiological Studies-Depression Index (CES-D)] during the previous week. Infants were tested using a two-screen preference procedure in which they were presented side-by-side videos of different facial expressions modeled by one female reciting a children's story. A centrally located speaker was used to present a vocal expression soundtrack that matched one of the facial expressions. Separate analyses of variances (ANOVAs) were conducted to analyze the proportion total matching and proportion total looking to the happy and sad expressions. Infants of mothers who reported depressive symptoms displayed less accurate matching of the happy facial and vocal expressions and looked more to sad facial expressions compared to infants of mothers who had not reported depressive symptoms above the normal range. Infants' performance on the expression matching task appears to be related to their primary caregivers' reports of depressive symptoms during the previous week. However, other factors that may be related to the group differences also need to be considered. For example, maternal reports of depressive symptoms may be a marker for other underlying factors that may have affected their infants' performance.

RESUMEN: Este estudio investigó el apareamiento de la expresión vocal y la facial en 24 infantes de 10 meses. La mitad de las madres había reportado síntomas depresivos (v.g. altos puntajes en el CES-D) durante la semana anterior. Los infantes fueron puestos a prueba usando un procedimiento de preferencia con dos pantallas. Se les presentó al mismo tiempo videos de diferentes expresiones faciales modeladas por una mujer que contaba una historia para niños. Un altavoz central se usó para presentar el sonido de una expresión vocal que correspondía a una de las expresiones faciales. ANOVAs separadas fueron llevadas a cabo para analizar la total proporción de emparejamiento y la proporción total de mirada a las expresiones felices y tristes. Los infantes de madres que habían reportado los síntomas depresivos mostraron menos efectividad de apareamiento de las expresiones vocales y faciales de felicidad, y miraron más hacia las expresiones faciales de tristeza, comparados con los infantes de madres que no habían reportado síntomas depresivos más allá de lo normal. La actuación de los infantes en esta tarea de apareamiento de expresiones parece estar relacionada con los reportes de síntomas depresivos durante la semana anterior reportados por quienes primariamente les cuidaban. Sin embargo, otros fac-
