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 A strong simple effect of Source on perceived expertise (η²p=.417): the researcher was rated more expert than the consumer. → Colin Lescarret 2022
q3 i3 A main effect of Source on perceived trustworthiness (η²p=.185): the researcher was rated more trustworthy than the consumer. → Colin Lescarret 2022 (2)
Evidence¶
Colin Lescarret 2022¶
Colin Lescarret, Julien Magnier, Valérie Le Floch, Jean-Christophe Sakdavong, and 2 more. (2022). Do you trust this speaker? The impact of prompting on middle-school students’ consideration of source when watching conflicting videos. Preprint, Research Square. https://doi.org/10.21203/rs.3.rs-1998147/v1
q3 · i3 · causal · r2
Mixed ANOVA on post-viewing perceived expertise ratings (McCroskey items, α=0.88) with effect size "η²p=.417" (F(1,254)=182.049, p<.001). Students judged the researcher more expert than the consumer, 95% CI [4.99:5.31] vs [3.14:3.47], M difference=1.85, t(254)=13.5, pbonferroni<.001, supporting Hypothesis 2a.
"Within-subjects effects revealed a strong simple effect of the factor Source, F(1,254)=182.049, p<.001, η²p=.417"
Colin Lescarret 2022 (2)¶
Colin Lescarret, Julien Magnier, Valérie Le Floch, Jean-Christophe Sakdavong, and 2 more. (2022). Do you trust this speaker? The impact of prompting on middle-school students’ consideration of source when watching conflicting videos. Preprint, Research Square. https://doi.org/10.21203/rs.3.rs-1998147/v1
q3 · i3 · causal · r2
Mixed ANOVA on perceived trustworthiness ratings (α=0.85) with effect size "η²p=.185" (F(1,125)=57.595, p<.001). The researcher was judged more trustworthy than the consumer, 95% CI [4.89:5.20] vs [4.02:4.31], M difference=0.886, t(245)=7.59, pbonferroni<.001.
"A main effect of the factor Source was noted, F(1,125) = 57.595, p<.001, η²p=.185"

- Watching the sourcing instructional video unexpectedly lowered students' trustworthiness ratings of the interviewees — related
- Learners are more willing to act on feedback when they perceive the sender as credible and trustworthy — related
