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? Voxel-wise ANOVA showed a main effect of group with reduced right superior temporal activation but increased posterior parietal (precuneus) and prefrontal activation in older subjects. → Wong Patrick C. M. 2009

q3 · i? · associational · r1
Three-dimensional mixed effects voxel-wise ANOVA on fMRI beta values from 24 subjects (12 younger, 12 older) across three listening conditions. Table 1 cluster statistics showed e.g. right aSTG/insula Group F(1,22) = 16.617, p < 0.001 (Young > Old) and right precuneus Group F(1,22) = 15.391, p < 0.001 (Old > Young).
"Generally speaking, in terms of sensory area, older subjects showed a reduced activity in the right superior temporal region. However, for posterior parietal (precuneus) and prefrontal (dorsal medial) areas, older subjects generally showed increased activation."
Discussion¶
Learner Variables¶
- Auditory Processing — 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
- Activation in frontal and parietal cognitive regions is positively correlated with speech-in-noise behavioral performance in older listeners, supporting a compensatory role — related
- Group x condition interactions show condition-dependent activation differences in superior temporal, parietal, cingulate, medial frontal, and middle temporal regions — 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
