Our previous work demonstrated that changing the interaction style via different feedback etiquette strategies has differential effects on students\u2019 motivation, confidence, satisfaction, and performance. The best etiquette strategy was also determined by user frustration. <\/jats:p><\/jats:sec><jats:sec><jats:title>Method:<\/jats:title><jats:p> Based on these findings, a rule set was developed that systemically selected the proper etiquette strategy to address one of four learning factors (motivation, confidence, satisfaction, and performance) under two different levels of user frustration. We explored whether etiquette strategy selection based on this rule set (systematic) or random changes in etiquette strategy for a given level of frustration affected the four learning factors. Participants solved mathematics problems under different frustration conditions with feedback that adapted dynamic changes in etiquette strategies either systematically or randomly. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> The results demonstrated that feedback with etiquette strategies chosen systematically via the rule set could selectively target and improve motivation, confidence, satisfaction, and performance more than changing etiquette strategies randomly. The systematic adaptation was effective no matter the level of frustration for the participant. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> If computer tutors can vary the interaction style to effectively mitigate negative emotions, then ITS designers would have one more mechanism in which to design affect-aware adaptations that provide the proper responses in situations where human emotions affect the ability to learn. <\/jats:p><\/jats:sec>","DOI":"10.1177\/0018720818765266","type":"journal-article","created":{"date-parts":[[2018,3,28]],"date-time":"2018-03-28T16:06:35Z","timestamp":1522253195000},"page":"510-526","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Affect-Aware Adaptive Tutoring Based on Human\u2013Automation Etiquette Strategies"],"prefix":"10.1177","volume":"60","author":[{"given":"Euijung","family":"Yang","sequence":"first","affiliation":[{"name":"Iowa State University, Ames"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6386-4787","authenticated-orcid":false,"given":"Michael C.","family":"Dorneich","sequence":"additional","affiliation":[{"name":"Iowa State University, Ames"}]}],"member":"179","published-online":{"date-parts":[[2018,3,28]]},"reference":[{"key":"bibr1-0018720818765266","doi-asserted-by":"publisher","DOI":"10.1007\/s40593-014-0023-y"},{"key":"bibr2-0018720818765266","first-page":"30","volume-title":"Proceedings of the 7th International Conference on Learning Sciences","author":"Baylor A.
