Amusia is a deficit in musical memory, recognition, and in pitch processing that people can be born with or acquire through brain damage. Some people may think of themselves as being "tone-deaf", but most of these "bad" singers are just that. People with amusia are so unable to hear tones that they even struggle to differentiate between questions and statements when spoken. Language, like music, uses sound to convey meaning; be it a story, or simply an emotion. In fact, music and spoken language use many of the same structural elements: pitch, duration, intensity and melodic contour, to name a few. Melodic contour is the pattern in which pitch changes from high to low over time. This contouring of pitch is often used to express emotion in music. The emotional effect of contouring is appreciated across many cultures and across many age groups. In speech, melodic contour is created by intonation, which allows us to place emphasis upon certain words and distinguish the purpose of the sentence; e.g. whether it is a question, statement or command. These comparisons provide evidence for the overlap of brain areas and mechanisms that underlie speech and music processing. In addition, the storing of sound patterns in short-term memory is also overlapping for both language and music.

While this article primarily addresses the phenomenon of dysmusia, difficulty in reading music, it also talks about the cognitive underpinnings of music reading. In the brain, reading music is a widespread, multi-modal activity, meaning that many different areas of the brain are involved at the same time. It includes motor, visual, auditory, audiovisual, somatosensory, parietal and frontal areas in both hemispheres and the cerebellum - making music reading truly a whole brain activity. With training, the neural network strengthens. Even reading a single pitch activates this widespread network in musicians. The article also reiterates a pattern that researchers are finding: while text and music reading share some networks, they are largely independent. The pattern of activation for reading musical symbols and letters is different across the brain. Scientists have determined this via studies of patients with limited brain damage, as brain injury impaired reading of one coding system but spared the other.

Author Sena Moore writes about how music can re-wire our brains for speech. Singing and speaking activate similar areas on both sides of the brain, primarily in the motor production and sensory feedback areas. Singing, however, also activates the right hemisphere in some areas more strongly than the left. Speech is a left-hemisphere-dominate function. In other words, similar networks in the brain associated with vocal production are activated when a person is singing and when s/he is speaking. And the "stronger right hemisphere" activation supports the clinical observation that those who cannot speak because of damage to the left hemisphere speech areas known as Broca's area can still produce words by singing them.

What does recent research say about the potential benefits of bilingual education? Here are the main 6 findings: 1. Attention: "[Bilinguals] can pay focused attention without being distracted and also improve in the ability to switch from one task to another," says Sorace. Do these same advantages accrue to a child who begins learning a second language in kindergarten instead of as a baby? We don't yet know. Patterns of language learning and language use are complex. But Gigi Luk at Harvard cites at least one brain-imaging study on adolescents that shows similar changes in brain structure when compared with those who are bilingual from birth, even when they didn't begin practicing a second language in earnest before late childhood. 2. Empathy: bilingual children as young as age 3, because they must follow social cues to figure out which language to use with which person and in what setting, have demonstrated a head start on tests of perspective-taking and theory of mind - both of which are fundamental social and emotional skills. 3. Reading (English): students enrolled in dual-language programs outperformed their peers in English-reading skills by a full school year's worth of learning by the end of middle school. 4. School performance and engagement: compared with students in English-only classrooms or in one-way immersion, dual-language students have somewhat higher test scores and also seem to be happier in school. Attendance is better, behavioral problems fewer, parent involvement higher. 5. Diversity and integration: Because dual-language schools are composed of native English speakers deliberately placed together with recent immigrants, they tend to be more ethnically and socioeconomically balanced. And there is some evidence that this helps kids of all backgrounds gain comfort with diversity and different cultures. 6. Protection against cognitive decline and dementia: actively using two languages seems to have a protective effect against age-related demen

There is growing concern that as well as addicting users, technology is contributing toward so-called "continuous partial attention", severely limiting people's ability to focus, and possibly lowering IQ. One recent study showed that the mere presence of smartphones damages cognitive capacity - even when the device is turned off. "Everyone is distracted," Rosenstein says. "All of the time."

In recent studies, Professor Gabrielle S. Adams, of the London Business School, found that misunderstandings often exist between the victims of harm and the people who committed the harm. In many cases, the transgressors did not intend a negative effect, whereas the victims tended to think that the damage was intentional. In addition, transgressors frequently felt guilty and wanted to be forgiven much more than their victims realized. When someone feels wronged, it can help to actively empathize with the person who is perceived as the wrongdoer, according to a study that Professor Adams conducted along with M. Ena Inesi, also of the London Business School. That can enable the victim to realize that the transgressor may well wish to be forgiven, their study found. By making it a point to resolve conflicts by encouraging empathy and forgiveness, workers and managers can improve workplace conditions.

"...people who speak more than one language don't exhibit symptoms of Alzheimer's disease until they have twice as much brain damage as unilingual people. It's the first physical evidence that bilingualism delays the onset of the disease. ... Despite the fact that both groups performed equivalently on all measures of cognitive performance, the scans of the bilingual patients showed twice as much atrophy in areas of the brain known to be affected by Alzheimer's."

This article is about the Icelandic language, which is seen as a source of identity and pride, is being damaged by the widespread use of English. Former president of Iceland, Vigdis Finnbogadottir, is worried that the Icelandic language will end up in the "Latin bin".

Neuroimaging studies suggest that sign languages are complex linguistic systems processed much like spoken languages, even though they're gestural/visual, not oral. Wernicke's area activates when perceiving sign language; Broca's when producing sign language. In deaf people, lesions in left hemisphere "speech centres" like Broca's and Wernicke's areas produced significantly more sign errors on naming, repetition and sentence-comprehension tasks than signers with damaged right hemispheres.

The author, a specialist and researcher in linguistics and discourse analysis, was interested in communication between individuals from different cultures. The misunderstandings it provokes are often based on unconscious reflexes and reference points which makes them all the more damaging. Communication between humans would be very difficult, if not impossible, without discursive memory. Our memories allow us to understand each other. Gregory Charles says in a tweet after the attack at the Grand Mosque in 2017, "Every nasty word we utter joins sentences, then paragraphs, pages and manifestos and ends up killing the world." This idea is defined by specialists in discourse analysis by theconcent of interdiscoursement. Not being aware of this discursive mechanism can cause many misunderstandings. Understanding it certainly helps to communicate better. Putting yourself in your audience's place is the key to good communication.

The Latin word anathema has evolved over time. Today, it means "a strongly disliked person or thing," e.g. "bullying is anathema to me." In medieval times, however, "anathema" means "an excommunicated person, also the curse of excommunication." In medieval, pre-printing press times, books were highly valued and rare, as they were laboriously handwritten by monks, and sometimes took years to produce. Given the extreme effort that went into creating books, scribes and book owners had a real incentive to protect their work. They used the only power they had: words. At the beginning or the end of books, scribes and book owners would write dramatic curses threatening thieves with pain and suffering if they were to steal or damage these treasures. They did not hesitate to use the worst punishments they knew-excommunication from the church and horrible, painful death. Steal a book, and you might be cleft by a demon sword, forced to sacrifice your hands, have your eyes gouged out, or end in the "fires of hell and brimstone." "These curses were the only things that protected the books," says Marc Drogin, author of Anathema! Medieval Scribes and the History of Book Curses. "Luckily, it was in a time where people believed in them. If you ripped out a page, you were going to die in agony. You didn't want to take the chance."

Researchers have found that people who speak multiple languages are twice as likely to recover their mental functions after a stroke as those who speak one language. The study gathered data from 608 stroke patients in Hyderabad, India, who were assessed, among others, on attention skills and the ability to retrieve and organise information. Bilinguals and multilinguals have better cognitive reserve - an improved ability of the brain to cope with damaging influences such as stroke or dementia - due to the mental challenge of speaking multiple languages and switching between them.

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.
