Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Children with language or attention disorders are more impaired than normally developing children by noise in speech perception tasks. → Klatte M 2013 q2 i? Children tested in their second language show a stronger noise effect than native children. → Klatte M 2013 (2)

Evidence¶

Klatte M 2013¶

Klatte M, Bergström K and Lachmann T (2013) Does noise affect learning? A short review on noise effects on cognitive performance in children. Front. Psychol. 4:578. https://doi.org/10.3389/fpsyg.2013.00578

q2 · i? · review · r2

The review attributes this finding, citing Geffner et al. and Ziegler et al., to the mediating role of linguistic competence and selective attention; the reviewed studies' designs are not described in the review.

"children with language or attention disorders are still more impaired than normally developing children by noise in speech perception tasks (Geffner et al., 1996; Ziegler et al., 2005, 2009 )"

Klatte M 2013 (2)¶

q2 · i? · review · r3

The review reports, citing Crandell and Smaldino, that "A stronger noise effect is also evident for children tested in their second language when compared to native children".

"A stronger noise effect is also evident for children tested in their second language when compared to native children (Crandell and Smaldino, 1996 )."

Discussion¶

Learner Variables¶

Attention — predictor: learners who differ on it differ in outcomes
Reading and Language — predictor: learners who differ on it differ in outcomes
English-Learner Status — predictor: learners who differ on it differ in outcomes

Children's speech perception in noise is more impaired than adults', requiring higher signal-to-noise ratios for comparable performance — related
Noise impairs children's performance in complex listening tasks beyond simple identification, with children affected more than adults — related
Children are more susceptible than adults to the effects of environmental noise on cognitive performance — possibly the same claim (merge candidate)
Most children with emotional and behavioral disorders have undiagnosed language impairment — related
Children with specific language impairment show reduced selective attention to and integration of audiovisual speech — related
