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? A condition × group interaction showed early stress and control groups differed more in reversal than in acquisition. → Harms Madeline B. 2018

q3 · i? · associational · r2
A 2 (condition) × 2 (trial type) × 2 (group) ANOVA on blocks 2–8 found a condition × group interaction: "early stress and control groups differed more in reversal" than in acquisition, indicating flexibility demands amplified the deficit.
"there was a condition × group interaction, F(1,45) = 6.40, p <.02, which reflects that early stress and control groups differed more in reversal, F(1,47) = 12.58, p <.001, than in acquisition F(1,47) = 6.53, p <.02)."
Discussion¶
Related Claims¶
- ACC activation to reward during reversal is positively associated with reversal learning performance in stress-exposed adolescents — related
- Stress-exposed adolescents show impaired cognitive flexibility in reversal learning — related
- Stress-exposed adolescents learn reward-punishment associations more slowly than controls during acquisition — related
- Lifetime stress severity correlates with poorer learning performance and reduced putamen/ACC activation — related
- Nonmaltreated adolescents are more accurate than maltreated adolescents on a go/no go task, with the group difference more pronounced on no go trials requiring inhibitory control — related
