Description¶

The review recommends that future work fill identified gaps and report measures precisely. It concludes that "being specific about the target and background signal as well as the tested cognitive subdomain and employing the full range of available stimuli may be a way to draw out further variability in association." It also identifies cognitive performance and SiN perception combinations that have not been tested, including alerting and orienting, where only two and one studies existed and no meta-analysis was possible.

Design Implications¶

Context¶

Requirements¶

• Studies must report the SiN target type, masker type, and cognitive subdomain so results can be categorized and pooled

Constraints¶

• Some combinations (e.g., phoneme or word targets, ≤2-talker babble with most subdomains) currently lack the minimum four studies the review required for meta-analysis

Target Learners¶

• Researchers of adult speech perception and cognitive hearing science

Target Learning Goals¶

• Designing studies that resolve which cognitive abilities support speech-in-noise perception under which listening conditions

Claims¶

• Cognitive subdomains differ in association strength with SiN perception, from r = .18 (crystallized IQ, nonsignificant) to r = .39 (processing speed) [+W]
• Working-memory associations with SiN perception appear strongest under informational masking and sentence targets (r up to .43) [+W]
