An ironic statement transmits the opposite meaning of its literal counterpart. The cognitive processes that may support the interpretation of irony include the Theory of Mind (ToM), executive functions, and processing style. The brain areas associated with irony detection are the medial prefrontal cortex, inferior frontal gyrus (IFG), posterior superior temporal gyrus (pSTG), precuneus, and inferior parietal lobule, among others. This study aims to analyze the cognitive processes and neural correlates involved in irony detection in Mexican adults. Forty-five participants underwent a cognitive assessment and performed a contextual discrepancy task during fMRI acquisition. The behavioral results showed that the detection of nonliteral statements (irony, unrelated, and white lies) requires ToM and verbal abilities. In addition,...

Thus, it has been proposed to be a good indicator of social communication ability. Prosody and facial expression are two crucial paralinguistic cues that can facilitate the understanding of ironic statements. The primary aim of this study was to create and evaluate a task of irony identification that could be used in neuroimaging studies. We independently evaluated three cues, contextual discrepancy, prosody and facial expression, and selected the best cue that would lead participants in fMRI studies to identify a stimulus as ironic in a reliable way. This process included the design, selection, and comparison of the three cues, all of which have been previously associated with irony detection. The secondary aim was to correlate irony comprehension with specific cognitive functions. Results showed that psycholinguistic properties could differentiate irony ...
