q2 i? Early sign enhancement positively predicted CI-HS language after controlling early language, but sign enhancement measured in adolescence negatively predicted language outcomes. → Geers Ann E. 2011

Authors' interpretation in the Discussion of the regression findings: early sign enhancement (β = −0.181, p = .003 in Table 4 step 3) was positive once early language was controlled, whereas CI-HS sign enhancement (β = −.345, p <.001 in Table 5 step 1) was negative. The authors attribute the reversal to children with early sign enhancement having more room for improvement.

"Students with early sign enhancement exhibited higher CI-HS language scores after variance due to CI-E language was controlled. This means that signing children made greater language gains between the CI-E and CI-HS test sessions."
