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 i3 For bilateral MTG, positive brain-behavior correlations were found in the Quiet and SNR 20 conditions but not in the SNR -5 condition in older subjects. → Wong Patrick C. M. 2009

Brain-behavior correlation analysis in the older group (n = 12) for bilateral MTG clusters. Right MTG correlated with accuracy in Quiet (r = .786, p < .001) and SNR 20 (r = .678, p = .008) but not SNR -5 (r = .336, p = .143); left MTG showed a similar pattern (r = .552, p = .031; r = .492, p = .052; r = .328, p = .149).
"For the right MTG [63 −10 −4; 792 cubic-mm], a significant positive correlation was found in the Quiet [r = .786, p < .001] and SNR 20 [r = .678, p = .008] conditions but not the SNR -5 condition [r = .336, p = .143]."
Discussion¶
Learner Variables¶
- Auditory Processing — predictor: learners who differ on it differ in outcomes
Related Claims¶
- 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
- Older adults show reduced accuracy in severe noise (SNR -5) but perform comparably to younger adults in quiet and moderate noise (SNR 20) — related
- 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
