Modern Psychology of Reasoning is driven to know what kinds of strategies subjects use to make inferences and the variables which determine the conclusions reached. To that end, empirical investigation has used several experimental tasks and paradigms. This work centres on one in particular: The THOG problem. The fundamental objectives of it are: to present the main lines of empirical investigation developed around this task and set out the most relevant theoretical explanations which have analysed reasoning with the THOG. Likewise, the repercussion which the research has had on this hypothetico-deductive problem will be analysed, for the general study of human reasoningeng© 2019 The AuthorsTHOG problemDisjunctive reasoningDeductionHypothesis testingHypothetico-deductive reasoningDual process theoryTheory of hypothetical thinkingMental models theoryCognitive psychologyReasoningThinkingconference outputopen access
