Dr. Joy Hirsch, head of Memorial Sloan-Kettering Hospital's functional M.R.I. Laboratory, and her graduate student, Karl Kim, found that second languages are stored differently in the human brain, depending on when they are learned. Babies who learn two languages simultaneously, and apparently effortlessly, have a single brain region for generating complex speech, researchers say. But people who learn a second language in adolescence or adulthood possess two such brain regions, one for each language. To explore where languages lie in the brain, Dr. Hirsch recruited 12 healthy bilingual people from New York City. Ten different languages were represented in the group. Half had learned two languages in infancy. The other half began learning a second language around age 11 and had acquired fluency by 19 after living in the country where the language was spoken. With their heads inside the M.R.I. machine, subjects thought silently about what they had done the day before using complex sentences, first in one language, then in the other. The machine detected increases in blood flow, indicating where in the brain this thinking took place. Activity was noted in Wernicke's area, a region devoted to understanding the meaning of words and the subject matter of spoken language, or semantics, as well as Broca's area, a region dedicated to the execution of speech, as well as some deep grammatical aspects of language. None of the 12 bilinguals had two separate Wernicke's areas, Dr. Hirsch said. But there were dramatic differences in Broca's areas, Dr. Hirsch said. In people who had learned both languages in infancy, there was only one uniform Broca's region for both languages, a dot of tissue containing about 30,000 neurons. Among those who had learned a second language in adolescence, however, Broca's area seemed to be divided into two distinct areas. Only one area was activated for each language. These two areas lay close to each other but were always separate, Dr. Hirsch s

This article talks about how social media platforms such as Twitter, Facebook and Reddit have helped researchers track the dynamic of a relationships of people who have broken up. There are signs you might be able to detect when a relationship is about to end, even before either person consciously aware of this. The subtle changes in language leading up to a breakup, such as the use of "I"-words, talking more about other people than ideas, and referencing their partner quite a bit (because their identities are still so strongly knit), for example, can be seen as evidence of an impending split.

A Johns Hopkins study found that damage to a key structure in the brain may explain why some stroke patients can't perceive sarcasm. Researchers looked at 24 people who had experienced a stroke in the right hemispheres of their brains. Those with damage to the right sagittal stratum tended to have trouble recognizing sarcasm, the researchers found. This bundle of neural fibers connects a number of brain regions, including those that process auditory and visual information. Sarcasm can be hard to interpret; it's a complex way to communicate. First, the person has to 1. understand the literal meaning of what someone says 2. detect the components of sarcasm: a wider range of pitch, greater emphatic stress, briefer pauses, lengthened syllables and intensified loudness relative to sincere speech "There're a number of cues people use, and it's both facial cues and tone of voice," noted Dr. Argye Hillis, a professor of neurology at Johns Hopkins University School of Medicine.

This article discusses the language of lying. It talks about liars' tendencies and patterns. Lying is very complex, but language itself is very good lie-detector.

This article talks about general language disorders, how to detect impairments, options for treatment, and much more. More specifically, one portion of the article focuses on receptive versus expressive forms of language, and the characteristics that fall beneath each of these categories. Lastly, the article addresses how parents can help their child succeed from a young age.

In this article, the author explains that on top of body language, some language cues can also detect a liar. It mentioned things like liars trying not using first person pronouns and increased use of negative statements that could be subconsciously mirroring the negative emotions a liar may feel such as fear or guilt.

This paper discusses how scientists attempted to teach children with autism to understand sarcasm. Sarcasm is a prominent force in everyday social interactions, and thus enabling kids with ASD to pink up on these subtleties benefits their relationships. The experiment, though it had a small sample size, was successful, using rules and other forms of training to give autistic children guidelines to follow.

This article explains some of the many harmful effects AI and voice replication are having on the growing misinformation crisis. Some cases paint certain political figures in a negative light by creating audio clips of them saying damaging things. Between political influence and scams, several problems arise from the cheep price and accessibility of sophisticated AI programs.
