Subclaims¶

q3 i? Significantly better right-ear results (right-ear advantage) were found on the Dichotic Words and Dichotic Sentences subtests. → Iva I. Hrastinski 2023 q3 i? On the Dichotic Sentences task, the right ear advantage decreased with increasing age; a similar trend on Dichotic Words was not statistically significant. → Iva I. Hrastinski 2023 (2)

Wilcoxon signed rank tests of ear differences across the sample. The article reports "significantly better results in the right ear, or a right-ear-advantage (REA), was noted for Dichotic Words (Z = -8.60, p = 0.00 1 ) and Dichotic Sentences (Z = -7.22, p = 0.001) subtests."

q3 · i? · associational · r2

Age-specific ear analysis on the Dichotic Sentences subtest. The article reports "the right ear advantage decreased with increasing age," while for Dichotic Words a similar trend was observed but without statistically significant differences.

"Furthermore, age-related ear differences were noted on the Dichotic Sentences task, where the right ear advantage decreased with increasing age."

Discussion¶

Related Claims¶

• Dichotic listening subtests were the most challenging PSP-1 tasks, especially for children with auditory processing difficulties
• PSP-1 performance increases with age across grades 1–4, with significant differences between adjacent age groups on total score
• Monolingual and bilingual children perform the dichotic comprehension task equivalently, with both groups finding English–English interference hardest
• Approximately 2.9% of Croatian grade 1–4 pupils meet diagnostic criteria for auditory processing disorder on the PSP-1 screening battery
