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.
q3 i? Normal-hearing 18- and 21-month-olds looked significantly longer to the target than the nontarget, while 12- and 15-month-olds did not. → Derek M. Houston 2012
Evidence¶
Derek M. Houston 2012¶
Derek M. Houston, Jessica Stewart, Aaron Moberly, George Hollich, and Richard T. Miyamoto. (2012). Word learning in deaf children with cochlear implants: effects of early auditory experience. Dev Sci. 2012 May ; 15(3): 448–461. https://doi.org/10.1111/j.1467-7687.2012.01140.x
q3 · i? · associational · r2
Repeated-measures ANOVA on NH groups' longest looks during test blocks. The 21-month-olds showed a significant target preference (F(1, 27) = 7.05, p = .01, ηp2 = .21); 12- and 15-month-olds did not look significantly longer to the target versus the nontarget.
"Looking time preference for the target approached statistical significance in the 18-month-olds (F(1, 24) = 3.06, p = .08, ηp2 = .11) and was significant in the 21-month-olds (F(1, 27) = 7.05, p = .01, ηp2 = .21)."
Discussion¶
Related Claims¶
- Early implanted children and their NH age-matched peers demonstrated word learning, while late implanted children did not unlike their peers — related
- Early implanted children performed significantly better on the word-learning task than late implanted children — related
- Word-learning performance correlates with vocabulary production in normal-hearing children but not with sentence length — related
