This systematic review and meta-analysis examined the effects of neurofeedback training (NFT) on attentional performance in healthy adults. Six databases (PubMed, Scopus, Web of Science, PsycInfo, JDreamIII, and Ichu-shi) were searched up to June 2022 for randomized controlled trials (RCTs) comparing attentional performance following NFT to a control group. Risk of bias was determined using the Cochrane Collaboration’s tool. We identified 41 RCTs for qualitative synthesis and 15 RCTs without high risk of bias (including 569 participants) for meta-analysis using a random-effects model. The overall effect of NFT on attentional performance was significant (standardized mean difference = 0.27, 95% confidence interval = 0.10–0.44). However, approximately half of the studies did not compare its effects with sham-NFT, and no significant pooled effect of NFT was found in the studies compared to a sham-NFT group. Furthermore, subgroup analyses revealed variable effects on individual attentional performance subsets (executive function, spatial orientation, and arousal). Future large-scale sham-controlled RCTs are needed to confirm the efficacy of NFT for improving attentional performance. |
