Argumentative modality regarding type of task and group size
The types of argumentation modes are analyzed according to the size of the group (dyads and triads) and the type of task (reading of tables of 3 entries, causal explanation of physical phenomena, decision making regarding moral dilemmatic situations and explanation cause of social phenomena). It is an experimental design in which the effect of the independent variables indicated (analyzed separately and interactively) on the type of argumentation is analyzed. Three types of argumentation are described: dialogical argumentative resolutions (RAD), “individualistic” argumentative resolutions (RAI), non-argumentative and dialogical resolutions (RNA). The results indicate that the “individualistic” argumentative resolutions prevail in dyads; while the triads prevails argumentative dialogical resolutions. Regarding the type of task, RAD predominate in logical tasks, while RAI are more frequent in opinion tasks. However, these relationships between type of evidence and argumentative modality are better clarified in an interactive analysis depending on the size of the group.
