Abstract(s)
"Foram estudadas cinco mulheres adultas com disfonia num estudo exploratório prospetivo, com cinco
voluntárias saudáveis, sem perturbação vocal, para fins de controlo. A metodologia utilizada foi descritiva,
comparativa e correlacional. Realizou-se um protocolo de avaliação complexo incluindo: análise da expressão facial
(sobrancelhas, olhos e boca) durante a leitura oral de textos que representam diferentes emoções (neutro, alegria,
tristeza) e narrativas sobre acontecimentos de vida. Foram delineados como objetivos: 1) identificar as expressões
faciais utilizadas nos diferentes contextos emocionais; 2) verificar a relação entre o grau de disfonia e as expressões
faciais para diferentes contextos emocionais; 3) verificar se as mulheres com e sem disfonia apresentam expressões
faciais significativamente diferentes nos vários contextos emocionais. Os resultados mostraram diferenças
estisticamente significativas (p<0,05) entre os dois grupos na manifestação de alegria através da face. Os sujeitos com
perturbação vocal são menos expressivos facialmente, em todos os contextos e significativamente menos expressivos
ao nível da emoção alegria. O grau de disfonia encontra-se associado a uma diminuição de manifestações faciais de
alegria e a uma maior manifestação de traços associáveis à tristeza, sendo a transmissão emocional é bimodal."
"Five adult speakers with vocal perturbation were studied in a prospective exploratory study, with five healthy volunteers without vocal perturbation for control purposes. The methodology used was descriptive, comparative and correlational. A complex evaluation protocol including: facial expression analysis (eyebrows, eyes and mouth during oral reading of passages representing different emotions (neutral, joy and sadness) and talking about a personal event were carried out. The aims of this study were: 1) identification of the facial expressions used in different emotional contexts; 2) verification of the relation between the rank of vocal perturbation and the facial expressions for different emotional contexts; 3) comparison between subjects to investigate whether significant differences exist between two groups of different voice conditions on the facial expressions used in different emotional contexts. The results show statistically significant differences (p <0.05) between the two groups in the facial expression of joy. Subjects with vocal disorder are less facially expressive in all contexts and significantly less expressive of joy. The degree of dysphonia is associated with a reduction of facial expressions of joy and greater manifestation of assignable sadness features. The emotional transmission is bimodal."
