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 i3 The predictability effect on CNV amplitude preceding targets and on target-P3 latency each correlated with the predictability benefit in reaction time. → Thillay A 2015

Pearson correlation analyses in the 36-participant sample related ERP predictability effects to the behavioral RT benefit. The study also reports the P3 latency predictability effect correlated with the RT benefit ("r = 0.519, b = 0.632, p = 0.001"), supporting CNV and P3 responses as markers of prediction abilities.
"Predictability effect on the amplitude of the CNV preceding targets (difference in CNV amplitude between randTs and predTs) at Cz was correlated with the predictability benefit in reaction time (difference in reaction time between randTs and predTs; r = 0.547, b = 0.009, p = 0.001)."
Discussion¶
Related Claims¶
- Old high performers show larger CNV amplitudes than old middle and low performers, comparable to middle-aged and young adults — related
- Behavioral performance on the toddler Oddball task is uncorrelated with target P3 amplitudes and latencies — related
- CNV and P2/N2 amplitudes are correlated in old high performers but not in other groups — related
- CNV and P3 scalp topographies show a frontal shift with increasing age during adolescence — related
- Predictability enhances P3 amplitude, CNV amplitude, and shortens target-P3 latency equally at all ages, indexing mature prediction encoding, preparation, and implementation — related
- Reaction-time benefit from predictive context is similar across ages 12–24, suggesting mature prediction abilities by age 12 — related
