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? For the frustrated instructor, agent presence interacted with emotion ratings, with the agent present condition better than the agent absent condition for recognizing frustration. → Lawson 2022

q3 · i? · causal · r2
Repeated measures ANOVA on ratings of the frustrated instructor in the Mturk within-subjects experiment. The article reports a significant "interaction between agent presence and emotion" favoring the agent present condition; with voice only, frustrated ratings were similar across all emotion scales.
"but there was an interaction between agent presence and emotion, F(3, 294) = 11.19, p < 0.001, in which the agent present condition appears to be better than the agent absent condition in recognizing the instructor's frustrated emotional tone."
Discussion¶
Related Claims¶
- Voice alone conveys the emotional tone of happy, content, and bored instructors as accurately as voice plus an embodied onscreen agent — related
- Participants rated happy and content instructors higher on positive than negative emotion scales, supporting the positivity hypothesis — related
- Participants detected emotional valence but did not distinguish between discrete emotions of the same valence — related
- Participants rated frustrated and bored instructors higher on negative than positive emotion scales, with the frustrated effect stronger when the agent was on screen — related
