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 i? At low ACS (-1 sd), the conditional indirect effect of public speaking anxiety on judged quality via speech length was negative and statistically significant (95% CI = -.13 to -.02). → Jones Christopher R. 2012

q3 · i? · associational · r1

Moderated-mediation analysis reported in a footnote, using bootstrap resampling (5000 samples) with the modmed macro in the same 61-participant sample. The conditional indirect effect was significant only at low ACS: "95%CI = (-.13, -.02)"; at mean and high ACS the confidence intervals included zero.

"At low ACS (-1 sd), the conditional indirect effect of PRCS on judged quality via speech length was negative and statistically significant—the interval did not contain zero: 95%CI = (-.13, -.02)."

Discussion¶

Learner Variables¶

Academic Anxiety — predictor: learners who differ on it differ in outcomes
Attention — moderator: an instructional effect differs with it

Public speaking anxiety is associated with poorer judged speech performance only among individuals low in attentional control — a broader claim this one bears on
Attentional shifting, but not focusing, significantly moderates the effect of speech anxiety on judged quality — related
Greater public speaking anxiety correlates with shorter and more poorly received speeches — a broader claim this one bears on
