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 Reaction times to predicted targets were significantly shorter than to random targets, with no effect of age group and no predictability × age interaction. → Thillay A 2015

Thillay A, Roux S, Gissot V, Carteau-Martin I, Knight RT, Bonnet-Brilhault F and Bidet-Caulet A (2015) Sustained attention and prediction: distinct brain maturation trajectories during adolescence. Front. Hum. Neurosci. 9:519. https://doi.org/10.3389/fnhum.2015.00519

Repeated-measures ANOVA on reaction times in the 36-participant detection task compared predicted versus random targets across the three age groups. The large predictability effect ("F(1,33) = 91.23, p< 0.001, ηp = 0.734") did not interact with age, indicating adolescents extracted and used predictive information as well as adults.
"The RT to predTs were significantly shorter than those to randTs ( F(1,33) = 91.23, p< 0.001, ηp = 0.734, power = 1.000). No effect of age group ( F(2,33) = 1.24, p = 0.302, ηp = 0.070), nor predictability × age interaction ( F(2,33) = 0.44, p = 0.645, ηp = 0.026) was found significant."

Related Claims¶
- The magnitude of ERP prediction markers correlates with the behavioral reaction-time benefit of predictability — 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
- Misconception-task accuracy increases with age between 12 and 15 years, with no age effect on reaction time — related
- Age did not significantly predict language learning aptitude in this adult sample — related
