Visual scanning of social stimuli in preterm and autism spectrum disorder children
ABSTRACT Objective: To evaluate the pattern of eye-gaze of preterm (PT), autism spectrum disorder (ASD) and neurotypical (Ty) children. Methods: A cross-sectional study with eight preterm (born with ≤2000 g weight), nine ASD and five Ty male children, between six and nine years old, was performed. T...

Summary: | ABSTRACT Objective: To evaluate the pattern of eye-gaze of preterm (PT), autism spectrum disorder (ASD) and neurotypical (Ty) children. Methods: A cross-sectional study with eight preterm (born with ≤2000 g weight), nine ASD and five Ty male children, between six and nine years old, was performed. The eye gaze was evaluated presenting a board with a couple in social interaction, and a video with four children playing with blocks, projected in a screen computer, successively, evaluating the time that the children looked at each stimulus. Results: Although all the groups focus on the central social figure with no significant differences, ASD presented significant differences in time fixation of the objects (p=0.021), while premature children fixated more time in the central social interaction than in the whole scene than typical children. Conclusions: Although this study found noteworthy differences in the eye-gaze patterns among the three groups, additional research with a more extensive participant pool is necessary to validate these preliminary results.
RESUMO Objetivo: Avaliar o padrão de fixação visual de crianças nascidas prematuras (PT), com transtorno do espectro do autismo (TEA/ASD) e neurotípicas (Ty). Métodos: Estudo transversal incluindo oito meninos prematuros (nascidos com peso ≤2000 g), nove TEA e cinco Ty, com idade entre 6 e 9 anos. A varredura visual foi avaliada apresentando-se imagem de casal em interação social e vídeo com crianças brincando. A figura e o vídeo foram projetados em tela de computador, sucessivamente, sendo avaliado o tempo de fixação para cada estímulo. Resultados: Apesar de os três grupos de crianças focarem o olhar na figura social central sem diferenças significativas, crianças com TEA apresentaram diferenças significativas no tempo de fixação em objetos (p=0,021), enquanto prematuros fixaram o olhar mais tempo na interação social central do que na cena como um todo. Conclusões: Embora tenham sido notadas algumas diferenças significativas nos padrões de olhar para os três grupos, é necessário realizar mais pesquisas com uma amostra maior para confirmar esses resultados iniciais. |
