The mechanisms of automated negotiation, such as argumentation, can be used in Ubiquitous Group Decision Support Systems (UbiGDSS) to help decision makers find a solution based on their preferences. However, the decision\u2010making process is much more than just a simple criteria and alternative analysis. There are many cognitive and affective issues that affect the outcome, and these issues should not be ignored; otherwise, the quality of the decision could be compromised. In this paper, we detail an UbiGDSS architecture and explore 2 cognitive and affective methods that are essential to the group decision\u2010making process. We explain how agents can reason about self\u2010expertise and other decision makers' credibility, and how agents can verify and react to tendencies throughout the decision\u2010making process. We intend agents to achieve higher quality and more consensual decisions. In any simulation environment that we tested, agents that analysed credibility, expertise, and\/or analysed tendencies always achieved a higher consensus compared to agents that used neither of the proposed methods. Likewise, agents that used neither of the proposed methods or only performed tendencies analysis obtained the worst average satisfaction levels for each simulation environment.<\/jats:p>","DOI":"10.1111\/exsy.12257","type":"journal-article","created":{"date-parts":[[2017,11,23]],"date-time":"2017-11-23T10:12:45Z","timestamp":1511431965000},"source":"Crossref","is-referenced-by-count":5,"title":["How cognitive and affective aspects can influence the outcome of the group decision\u2010making process"],"prefix":"10.1111","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1430-5465","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Carneiro","sequence":"first","affiliation":[{"name":"GECAD Instituto Superior de Engenharia do Porto R.
