In 2020 Adolfo García, a neurolinguist at Argentina’s College of San Andrés, experienced a prospect come across with a photographer who amused his products by chattering to them backward—the Spanish phrase casa (property) grew to become “asac,” for instance. Upon discovering that the photographer had been fluent in “backward speech” due to the fact childhood and was capable of holding a discussion solely in reverse, García established out to review the phenomenon.
His research on this amusing talking style drew adequate focus to garner him an Ig Nobel Prize, an award sponsored by Harvard University considering that 1991 for study that “first will make persons snicker and then consider.” Backward speech confers no realistic benefit to its speakers. Most likely it basically exists for the sheer enjoyment of the speaker and listener, who figure out the appears in asac or “onom,” which is from the Spanish term mono (monkey). Nonetheless, this skill, which García says was to begin with dismissed by his acquaintances and colleagues as “ridiculous and useless,” is by no means a complete squander because it offers insights into how the human mind processes language in atypical methods.
“We had the prospect to explore one thing unusual, even, at occasions, absurd,” García suggests of the 2020 Scientific Reviews study for which he and his crew won the Ig Nobel. This recognition took him by shock, especially taking into consideration that he did not carry on to go after this distinct line of investigation soon after the research was published. His investigation now focuses on addressing language problems in autistic people and in individuals with ataxia, Parkinson’s condition or neurodegenerative ailments. But García stays an ardent advocate for producing backward speak extra than a linguistic oddity. He hopes, in actuality, that his work will verify useful in developing additional helpful therapies for language issues.
All around the La Plata River estuary, which abuts the province of Buenos Aires and some components of southern Uruguay, the language of phrase inversion belongs to a style of slang termed lunfardo, which is the products of immigrant languages from the late 19th and early 20th hundreds of years. This linguistic marvel works by using only letters or syllables swapped from back to entrance. In lunfardo, the phrase vesre represents the Spanish term for “reverse”—revés—with its syllables pronounced backward.
There are still legions of passionate lunfardo speakers now. Hundreds of exchanges transform up in regular conversation: feca (café, or espresso), choborra (borracho, or drunk) or rioba (barrio, or neighborhood). In Argentina and Uruguay these phrases are element of the society. They typically clearly show up in tango lyrics but are sprinkled as solitary words and phrases into conversation by nearly all people, though not as constant backward speech as shown by the photographer encountered by García.
Backward speech can be practiced in any language that has a “transparent” grammar, that means that phonemes—the unique sound units of a language—have the exact same sound irrespective of their place relative to other sections of a word, in accordance to María José Torres Prioris, a researcher in the college of psychology at the University of Málaga in Spain and at the Biomedical Study Institute of Málaga, who co-authored the Scientific Stories examine.
Term reversals are achievable in languages this kind of as Spanish, Basque or some Mayan languages, in which there is a immediate one-to-one particular correspondence amongst letters and sounds. For occasion, Spanish has five vowels, and each individual one has a distinctive sound that remains reliable throughout all words. In distinction, English, considered an “opaque” language, has 12 various sounds for these very same five vowels. In Spanish, the letter A has a constant seem and is created the identical way, when in English, it can make diversified appears, as observed in terms such as “back” (/æ/) or “far” (/ɑ/). In some circumstances, it may well be listened to without the need of being explicitly written, such as in “cup” (/ʌ/). Torres Prioris acknowledges that persons can converse backwards in English as effectively, but the speaker and listener can get perplexed between how a word is pronounced and how it is penned. That confusion of sounds does not exist in Spanish.
Backward talking is not confined to the La Plata River area. In France talking backward is termed verlan, a phrase that is the inversion of the syllables of l’envers, indicating “the inverse.” Verlan includes expressions such as cimer for merci (thank you) or jourbon for bonjour (good day). Some thing related exists in Medellín, Colombia, the place folks carry on in parlache, and in Panama, which has slang named reversina.
Cultural adoration for backward communicate perhaps reaches an apex in San Cristóbal de La Laguna, a city in Spain’s Canary Islands exactly where citizens are pushing for formal recognition of backward discuss. In this article the custom acquired began in the 1930s by a barber who spoke backward. Nowadays people he affected have asked the United Nations Instructional, Scientific and Cultural Corporation (UNESCO) to declare the exercise an “intangible cultural heritage of humanity.” Some San Cristóbal inhabitants have even quarreled with Spanish-language professors and authorities at the Canarian Language Academy who contend that this way of speaking equates to nothing far more than a linguistic recreation.
The Ig Nobel–winning researchers’ prize consisted of an out-of-circulation Zimbabwean banknote and a PDF that could be printed out and folded to kind a miniature cola box. The backward speakers in their examine possessed an “extraordinary ability” to swiftly reverse terms (even invented types), sentences and texts. These men and women could rearrange seems but preserve a word’s identity effortlessly, García and Torres Prioris’s workforce discovered. As an alternative of expressing plata (money), for example, they reported atalp. They reversed the letters in the term, not the syllables, and even maintained the appropriate accents. “It is a a lot far more intricate mechanism” than a foolish sport, Garcia emphasizes.
In the Scientific Stories study, the scientists created many tasks to evaluate the participants’ capability to make words and phrases backward and forward. The scientists calculated accuracy and pace in rearranging phoneme sequences, and they acquired structural and purposeful magnetic resonance imaging recordings.
A person of the study’s results shows that the individuals experienced an potential to quickly interact in phrase reversal that could not be stated by, say, getting a remarkable doing work memory (the variety of memory that enables people to briefly try to remember a phone variety, for example). Additionally, these persons did not show any other reversal abilities, this sort of as mirror writing, or crafting in reverse.
Neuroimaging revealed that backward speakers experienced much more gray matter quantity and connections amid neurons, not only in areas connected with phoneme processing (along what is called the dorsal pathway of the still left hemisphere) but also in other mind places involved in semantic procedures, selected visual functions and cognitive manage. Backward speech therefore brings into participate in cognitive mechanisms past classical language circuits.
A different intriguing aspect of the team’s conclusions, in accordance to Torres Prioris, reveals that the brain plasticity shown by the study’s backward speakers enabled them to “accomplish the similar activity with distinct neural methods.”
María Castelló, an affiliate professor of research in integrative and computational neurosciences at Clemente Estable Organic Exploration Institute in Uruguay, who was not involved in this research, thinks that it has opened “a window into the mechanisms of phonological coding”—the recording of written, orthographic information and facts into a sound-based mostly code. Precisely, it sheds gentle on “an region that has been minor explored in neurolinguistics,” Castelló says.
“Neuroimaging experiments have disclosed that the distinct mind regions involved can vary among individuals, underscoring the plasticity of the human brain in adapting to extraordinary linguistic capabilities,” she adds. The most significant contribution of this analyze, Castelló states, is that it offering insights that enhance knowing of the neural mechanisms included in processing sounds and setting up text.
Backward speak may possibly seem to some like an absurd indulgence that does nothing far more than provoke laughter amid close friends in sites this kind of as San Cristóbal de La Laguna. But García and Torres Prioris argue that this investigation is suitable for a deeper comprehension of neurological ailments that influence language. “I just can’t say that this study has a immediate scientific influence, but I do feel it goes in that course,” Torres Prioris suggests.
Due to the fact the publication of the team’s posting, Torres Prioris has targeted on researching attribute indications of poststroke aphasia, which affects the means to discuss and success from accidents to the brain regions accountable for language. People with aphasia may perhaps show linguistic faults these kinds of as the inversion, substitution, addition or subtraction of phonemes when speaking. In this context, the identification of neural circuits associated with backward speech is, in her watch, “a phase forward” for the progress of noninvasive mind stimulation remedies for people with this affliction. And in the foreseeable future, she hopes to derive an efficient remedy from the final results of learning backward speech.
“When confronted with some thing seemingly absurd or absurd, it is quite simple to dismiss it as if scientific benefit lies in grandiose, groundbreaking and transcendent matters,” García suggests. “A lesson from this review is that if we see something absurd, and we are unsuccessful to find inspiration, we are not contemplating deeply plenty of.”
