Highlights

Visuo-attentional interventions improve reading outcomes in dyslexic children.
Improvements are equal or greater than other options and last at least two months.
Visual perceptual trainings can benefit reading fluency and comprehension.
Visually-based reading acceleration programs can improve reading accuracy and rate.
Action video games can increase reading rate and fluency.

Abstract

Dyslexia is associated with phonological and visuo-attentional deficits. Phonological interventions improve word accuracy and letter-sound knowledge, but not reading fluency. This systematic review evaluated the effectiveness of dynamic computerized visuo-attentional interventions aimed at improving reading for dyslexic and neurotypical children aged 5–15. Literature searches in Medline, PsycINFO, EMBASE, Scopus, ERIC, PubMed, Web of Science, and Cochrane Library identified 1266 unique articles, of which 18 met inclusion criteria (620 participants; 91.40% dyslexic). Three types of visuo-attentional interventions were identified. Results show that visual perceptual training (n = 5) benefited reading fluency and comprehension, visually-based reading acceleration programs (n = 8) improved reading accuracy and rate, and action video games (n = 5) increased rate and fluency. Visuo-attentional interventions are effective options for treating childhood dyslexia, improving reading generally equal to or greater than other strategies. Initial evidence indicates that visuo-attentional interventions may be efficacious in different orthographies, and improve reading for at least two months after intervention. Larger sample interventions on a wider range of reading skills with follow-up assessment are needed to further clarify their effectiveness.

5. Conclusions
The results of this review show that visuo-attentional interventions for dyslexia, though brief, are able to produce significant reading gains, without the need for explicit phonological or orthographic instruction, and for VPT and AVGs, also without any reading component. The
patterns of evidence show that VPT programs provide most benefit for reading fluency and comprehension, visually-based RAPs appear to improve reading accuracy and rate, while AVGS result in gains to reading rate and fluency. Moreover, improvements following visuo-attentional interventions are generally equal to or greater than other intervention options. The current literature, while limited, also suggests that visuo-attentional interventions can produce reading improvements that are maintained for at least two months following treatment and may also improve the reading skills of typically developing children. Emergent evidence also indicates that visuo-attentional interventions
benefit reading outcomes in both shallow and deep orthographies.
