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? Bilateral STG showed increased activation with noise in younger subjects but lower, condition-undifferentiated activation in older subjects; MTG showed the opposite pattern with increased activation in older subjects in SNR -5. → Wong Patrick C. M. 2009

q3 · i? · causal · r1
Voxel-wise mixed effects ANOVA (n = 24) identified regions with significant group x condition interactions (Table 2), e.g. right STG Interaction F(2,44) = 16.509, p < 0.001 (SNR -5: Young > Old, p = .005) and right MTG Interaction F(2,44) = 18.420, p < 0.001 (SNR -5: Old > Young, p = 0.028).
"In terms of sensory areas, bilateral superior temporal regions showed increased activation as noise increases in younger subjects, while an overall lower level of activation and activation undifferentiated by condition was seen in the older group"
Discussion¶
Learner Variables¶
- Auditory Processing — predictor: learners who differ on it differ in outcomes
- Sensory Integration — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Older adults show a more diffused cortical network involving frontal and ventral regions, whereas younger adults show a streamlined auditory network during speech-in-noise processing — related
- Older adults show reduced activation in auditory cortex and increased activation in prefrontal and precuneus regions during speech-in-noise processing — related
- Activation in frontal and parietal cognitive regions is positively correlated with speech-in-noise behavioral performance in older listeners, supporting a compensatory role — related
- Middle temporal gyrus activation in older listeners correlates with performance only in non-debilitating listening conditions, not in severe noise — related
- Older adults show reduced accuracy in severe noise (SNR -5) but perform comparably to younger adults in quiet and moderate noise (SNR 20) — related
- A peer audience differentially modulates fronto-parietal activation by age: increased in adolescents, decreased in adults — related
