“Mom, can you bring me a glass of juice?” a young woman comfortably says from the couch. “I didn’t realize you had both legs broken,” her mother quickly responds, criticizing her daughter’s lack of initiative.
Sarcasm is sharp and intense. It pushes irony to its extreme, typically aiming to challenge or ridicule. Comprehending it involves engaging multiple layers.neural connectionsimmediately and understanding how to adjust to the situation, which is why researchers examine it with special focus on mental and nervous system conditions.
Until now, knowledge about this form of biting humor was limited to its application in English. However, Argentine scientists have recently published thefirst preliminary resultsRegarding the Spanish language, it confirms that understanding sarcasm is a challenging task for the brain. One of the goals of the research is to explore if the difficulty in grasping sarcasm could serve as a dependable sign in diagnosing neurological conditions and mental health issues.
“I believe we will be able to offer that answer within a year,” says Bautista Elizalde Acevedo, one of the study’s contributors. He is a physician specializing in Biomedical Sciences and a researcher at the National Scientific and Technical Research Council of Argentina (CONICET). The researchers are conducting this study with the aim of utilizing it for patients withschizophreniaindividuals who frequently struggle to recognize sarcastic scenarios, figurative language, or intonation—messages where the meaning relies on the tone of voice—among other aspects of pragmatic communication.
The study is also groundbreaking: it employs a straightforward approach of presenting realistic scenarios in the form of comic books, which were entirely developed by the researchers. The experiment carried out in Spanish ultimately revealed more extensive neural connections compared to those conducted in English.
This research — in contrast to earlier studies — demonstrated the activation of a highly widespread brain network. “This is what sets it apart from other studies that have been conducted. We aren’t sure if it’s because we performed it in Spanish, or because our test involved a lower cognitive demand compared to the tasks used by others.”
“In those instances, a significant amount of previous information was needed to arrive at the sarcastic stimulus, whereas our approach was more straightforward and closely resembled real-life scenarios,” says Nicolás Vassolo, the study’s lead author. “In a basic image with simple text, we already had a stimulus that included sarcasm,” adds Vassolo, who holds a Psychology degree and works as a researcher at CONICET.
Sarcasm relies on irony and double meanings, which demands the ability to grasp another person’s thoughts and the tone they are using. Researchers refer to this mental skill — similar to empathy — as “theory of mind” (ToM).
“It’s not mind-reading; the individual grasps the direction of the conversation through the context, their facial expressions, and what they are saying to you,” explains Mariana Bendersky, one of the study’s authors. “This is essential for sarcasm. Without this comprehension, you’re confused. You interpret things literally: you might take it incorrectly or correctly, but you didn’t realize they were joking with you,” adds Bendersky, a medical doctor who is also the artist responsible for illustrating the comics used in the experiment.
As explained by Lucy Alba Ferrara, a neuroscience doctor and CONICET researcher, “language has a highly concise processing system in the brain, featuring key nodes that are frequently reused.” When this kind of humor is processed, these nodes connect with others that are more variable and widely distributed across the cortex.
This is because sarcasm overlaps with other abilities related to theory of mind, along with the contextual details needed for accurate interpretation. “That’s why the brain connections associated with sarcasm are so intriguing,” Ferrara notes.
This intricacy is one of the factors that make it challenging for AI-based language models to recognize sarcasm. They fail to reach the same degree of complexity as the neural connections that generateinterpersonal skills.
A comparable issue arises on social media. In the absence of context, body language, or vocal inflection, understanding becomes susceptible to a literal approach. “The words are present, so people can infer their meaning. It can be understood in multiple ways,” explains Bendersky. “Furthermore, it greatly reduces the richness of language, as messages are very brief, somewhat like telegrams, restricted by character limits, and not very elaborate. When you read them, you sense that their language and grammar are declining. If we take into account that this also influences the brain, it’s concerning.”
The research team will keep exploring the brain to compare the results of this study with those observed in individuals diagnosed with schizophrenia. “Now, we aim to examine a group in which the function shows changes directly in behavior—rather than just in the brain—and in this way, compare the two groups: healthy brains and those with some form of disorder,” explains Elizalde.
Nevertheless, setting aside mental health conditions, being healthy alone is not sufficient to understand sarcasm. You require a sense of humor, practical intelligence… and as the song saysLa Bamba goes, “un poco de gracia— a touch of elegance.
