However, studies investigating this attentional bias in individuals with ASD vary in paradigms and results. Methods We conducted a meta-analysis across different reaction time tasks, including dot-probe, spatial cuing, visual search and emotional Stroop tasks, to examine the attentional bias toward threatening emotional faces in individuals with ASD. Narrative synthesis further summarized possible moderators affecting attentional bias. Results We used systematic searches to identify 21 empirical studies with 1,805 participants in total (ASD n = 909). Individuals with ASD showed a small but significant attentional bias toward threatening emotional faces over other faces (g = 0.162), which was similar to individuals with typical development (g = 0.203). Moderator analysis showed that adults with ASD showed a larger attentional bias than children with ASD. For the dot-probe and spatial cuing paradigms, attentional bias toward threatening emotional faces was observed when stimuli were presented for less than 500 ms, and bias away from threatening emotional faces was shown when stimuli were presented for over 500 ms. For the visual search paradigm, attentional bias was significant in button-press tasks, but not in touch-screen tasks. Furthermore, attentional bias was only observed when the stimuli were schematic faces and reference materials were happy faces. Conclusions Individuals with ASD showed a small but significant attentional bias toward threatening emotional faces. Furthermore, significant moderators included stimulus presentation, response type, reference face type, stimulus type, and age. Thus, more research is needed to further explore attentional bias toward threatening emotional faces in individuals with ASD.

The effect of omega-3 fatty acid supplementation on autism spectrum disorder: A meta-analysis / Jia-Qi JING ; Li-Xin YI ; Chang-Jiang YANG in Research in Autism, 126 (August 2025)  

Public ISBD [article]  inResearch in Autism > 126 (August 2025) . - p.202642 Titre : The effect of omega-3 fatty acid supplementation on autism spectrum disorder: A meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Jia-Qi JING, Auteur ; Li-Xin YI, Auteur ; Chang-Jiang YANG, Auteur Article en page(s) : p.202642 Langues : Anglais (eng) Mots-clés : Omega-3 fatty acid  ASD  Meta-analysis Index. décimale : PER Périodiques Résumé : Background Omega-3 therapy for ASD is often used as a complementary and alternative medical approach, however, its impact on the core symptoms of ASD is controversial. Therefore, accurately determining the role of Omega-3 in ASD can establish a foundation for parents and doctors to formulate treatment plans. The current study aimed to include randomized controlled trials and provide a meta-analysis to evaluate the impact of Omega-3 fatty acids on the core symptoms of ASD. Method We searched the papers published in the Web of Science, PubMed, Medline, Scopus, EBSCO, SpringerLink, and Wiley Online Library databases until 10th April 2024 with 11 articles included. The meta-analysis evaluated the overall effects of Omega-3 fatty acids on core ASD behaviors and the effects on hyperactivity behavior, stereotype behavior, communication difficulty, and emotional difficulty. Results Results indicated that, compared to placebo, the Omega-3 fatty acids had a small and non-significant effect on the overall behavior [SMD= ?0.1, 95 % CI (?0.36,0.17), p = 0.47], with the same effect on hyperactivity behavior [SMD= ?0.24, 95 % CI (?0.55,0.08), p = 0.14], stereotyped behavior [SMD= ?0.2, 95 % CI (?0.47,0.07), p = 0.15], communication difficulty [SMD= ?0.09, 95 % CI (?0.42,0.24), p = 0.60], and emotional difficulty [SMD= ?0.15, 95 % CI (?0.45,0.14), p = 0.3]. Conclusions Overall, Omega-3 fatty acids have a minor and insignificant effect on ASD behaviors, which may be related to treatment protocol and appropriateness of participants. In the future, more large-scale and rigorous randomized controlled trials are needed to further obtain more convincing conclusions.
