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? Adolescents with early life stress histories responded less accurately throughout acquisition than controls, learning punishment associations more slowly. → Harms Madeline B. 2018

q3 · i? · associational · r2
Behavioral ANOVA of the acquisition condition in 29 early-stress and 22 control adolescents showed a main effect of group: "stress-exposed adolescents responded less accurately throughout the task". A group × time interaction for punishment trials indicated slower learning of punishment cues.
"There was also a significant main effect of group, showing that stress-exposed adolescents responded less accurately throughout the task F(1,49) = 7.5, p < .001."
Discussion¶
Learner Variables¶
- Affect Regulation — predictor: learners who differ on it differ in outcomes
