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 Across time, all participants in all conditions increased N-Back performance, with the largest increase from baseline to T1, reflected in a strong multivariate main effect of time. → Scheibe 2009
Evidence¶
Scheibe 2009¶
Scheibe, S., & Blanchard-Fields, F. (2009). Effects of Regulating Emotions on Cognitive Performance: What Is Costly for Young Adults Is not so Costly for Older Adults. Psychology and Aging, 24(1), 217-223. https://doi.org/10.1037/a0013807
q3 · i3 · causal · r2
Omnibus repeated-measures ANOVA of combined N-Back performance at baseline and three post-induction time points. The article reports a main effect of time with η2 = .48 and that "all participants in all conditions increased their performance." No further practice gains appeared at the two subsequent measurements.
"there was a strong multivariate main effect of time, F (3, 134) = 41.91, p = .001, η2 = .48. Across time, all participants in all conditions increased their performance, with the largest increase from baseline to T1."

- Instructions to maintain feelings of disgust do not disrupt working memory performance in either age group — related
- The experience of disgust per se does not affect the trajectory of working memory performance in either young or older adults — related
- The disgust film induction elevated disgust ratings comparably in young and older adults, with no age differences in reactivity or recovery after baseline — related
- Adults show higher overall working memory accuracy than adolescents, and adults but not adolescents increase startle reactivity with load — related
