coughing classical music

  • Todo está en silencio. Los instrumentos de cuerda, los de viento y percusión esperan la señal del director para empezar la pieza. Al otro lado está el público callado, tragando más espeso y conteniendo la tos. Hay alguien que no lo puede evitar y con el primer acorde empieza a toser. ¿Por qué siempre ocurre esto?
  • "Toda la estadística existente sugiere que la gente tose dos veces más durante los conciertos", le dijo Wagener a la BBC.
  • El especialista descubrió que la acción de toser no es completamente aleatoria. La pieza que se escucha también incita a toser más o menos.

  • "Si se trata de conciertos más modernos, como por ejemplo música clásica del siglo XX, los movimientos más lentos y los silencios son interrumpidos con mayor frecuencia".
  • cuando alguien empieza a toser y contagia a los otros.
  • "Creo que muchas personas cuando van a conciertos clásicos se dan cuenta que el nivel de ruido es mucho menor que la música a la que están acostumbradas a oir a través de sus auriculares o conciertos de música pop", agregó la pianista.
  • ese silencio en los conciertos acústicos es reconfortante, para otros puede originar inconformidad que se manifiesta en la acción de toser.
  • Andreas Wagener se mostró parcialmente de acuerdo con la teoría de Tomes, pues "cuando alguien va a un concierto (de música clásica) sabe que debe permanecer en silencio".
  • "Es una cuestión de etiqueta, saben que no deben hablar o caminar, hacer ruido o toser, pero la gente sigue tosiendo en exceso".
  • con la tos no se puede saber si es deliberado o involuntario.
  • "Creo que a veces la gente no esta consciente de como suena para el concertista. Es un factor muy distractor".

    I realize that this article is in Spanish, so those who don't understand the language will likely be confused, but I thought that it was very interesting, and related to TOK. Essentially, the article talked about a study that Andreas Wagener, a German scientist did, in which it was discovered that people cough twice as much at classical music concerts than otherwise. Wagener also found that the amount of coughing was not random; rather, it was dependent on the style, tempo, etc. of the music being played. The slow, more modern pieces often elicited more coughs. Additionally, Wagener found that, similar to how we think about yawning, coughing is contagious; one cough can cause an avalanche of other coughs. The article also noted the possibility that some of the coughing going on during a classical music concert may not be the typical, involuntary, reflexive cough, but a deliberate cough of social interaction. In terms of TOK, I thought that this article was most interesting in that, when put into a situation in which we may be uncomfortable (often with silence), we cough more. I related this to my own experiences at Friends, during MFW, when people often seem to cough out of a need for interaction. It would be interesting to see if Wagener could work with some geneticists and biologists to discover if a connection between slow classical music and more coughing is purely biological, or if it stems from another causation of human behavior.

  • a number of "social X-ray specs" that are set to transform how we interact with each other. By sensing emotions that we would otherwise miss, these technologies can thwart disastrous social gaffes and help us understand each other better.
  • In conversation, we pantomime certain emotions that act as social lubricants. We unconsciously nod to signal that we are following the other person's train of thought, for example, or squint a bit to indicate that we are losing track. Many of these signals can be misinterpreted - sometimes because different cultures have their own specific signals.

  • In addition to facial expressions, we radiate a panoply of involuntary "honest signals", a term identified by MIT Media Lab researcher Alex Pentland in the early 2000s to describe the social signals that we use to augment our language. They include body language such as gesture mirroring, and cues such as variations in the tone and pitch of the voice. We do respond to these cues, but often not consciously. If we were more aware of them in others and ourselves, then we would have a fuller picture of the social reality around us, and be able to react more deliberately.

  • Some of our body's responses during a conversation are not designed for broadcast to another person - but it's possible to monitor those too. Your temperature and skin conductance can also reveal secrets about your emotional state, and Picard can tap them with a glove-like device called the Q Sensor. In response to stresses, good or bad, our skin becomes clammy, increasing its conductance, and the Q Sensor picks this up.
  • Physiological responses can now even be tracked remotely, in principle without your consent. Last year, Picard and one of her graduate students showed that it was possible to measure heart rate without any surface contact with the body. They used software linked to an ordinary webcam to read information about heart rate, blood pressure and skin temperature based on, among other things, colour changes in the subject's face

  • The court decided that, although the doctor was innocent, circumcising an infant for non-medical reasons violates Germany's constitutional protection of every person's bodily integrity—and should thus be a crime.

What Is Synesthesia? Definition and Types - 0 views

shared by runlai_jiang on 15 Jan 18 - No Cached
  • The term "synesthesia" comes from the Greek words syn, which means "together", and aisthesis, which means "sensation." Synesthesia is a perception in which stimulating one sensory or cognitive pathway  causes experiences in another sense or cognitive pathway. In other words, a sense or concept is connected to a different sense or concept, such as hearing a color or tasting a word. The connection between pathways is involuntary and consistent over time, rather than conscious or arbitrary.
  • Types of SynesthesiaThere are many different types of synesthesia, but they may be categorized as falling into one of two groups: associative synesthesia and projective synesthesia. An associate feels a connection between a stimulus and a sense, w
  • There are at least 80 known types of synesthesia, but some are more common than others: Chromesthesia: In this common form of synesthesia, sounds and colors are associated with each other. For example, the musical note "D" may correspond to seeing the color green.Grapheme-color synesthesia: This is a common form of synesthesia characterized by seeing graphemes (letter or numerals) shaded with a color. Synesthetes don't associate the same colors for a grapheme as each other, although the letter "A" does appear to be red to many individuals. Persons who experience grapheme-color synesthesia sometimes report seeing impossible colors when red and green or blue and yellow graphemes appear next to each other in a word or number. Number form: A number form is a mental shape or map of numbers resulting from seeing or thinking about numbers.Lexical-gustatory synesthesia: This a rare type of synesthesia in which hearing a word results in tasting a flavor. For example, a person's name might taste like chocolate.Mirror-touch synesthesia: While rare, mirror-touch synesthesia is noteworthy because it can be disruptive to a synesthete's life. In this form of synesthesia, an individual feels the same sensation in response to a stimulus as another person. For example, seeing a person being tapped on the shoulder would cause the synesthete to feel a tap on

  • How Synesthesia WorksScientists have yet to make a definitive determination of the mechanism of synesthesia. It may be due to increased cross-talk between specialized regions of the brain. Another possible mechanism is that inhibition in a neural pathway is reduced in synesthetes, allowing multi-sensory processing of stimuli. Some researchers believe synesthesia is based on the way the brain extracts and assigns the meaning of a stimulus (ideasthesia).
  • Who Has Synesthesia?Julia Simner, a psychologist studying synesthesia at of the University of Edinburgh, estimates at least 4% of the population has synesthesia and that over 1% of people have grapheme-color synesthesia (colored numbers and letters). More women have synesthesia than men. Some research suggests the incidenc
  • Can You Develop Synesthesia?There are documented cases of non-synesthetes developing synesthesia. Specifically, head trauma, stroke, brain tumors, and temporal lobe epilepsy may produce synesthesia. Temporary synesthesia may result from exposure to the psychedelic drugs mescaline or LSD, from sensory deprivation, or from meditation.

  • We form beliefs in a haphazard way, believing all sorts of things based just on what we hear out in the world but haven’t researched for ourselves.
  • It turns out, though, that we actually form abstract beliefs this way: We hear something; We believe it to be true; Only sometimes, later, if we have the time or the inclination, we think about it and vet it, determining whether it is, in fact, true or false
  • “People are credulous creatures who find it very easy to believe and very difficult to doubt. In fact, believing is so easy, and perhaps so inevitable, that it may be more like involuntary comprehension than it is like rational assessment.”

  • Under any sort of pressure, they presumed all the statements were true, regardless of their labeling.
  • How we form beliefs was shaped by the evolutionary push toward efficiency rather than accuracy.
  • Before language, our ancestors could form new beliefs only through what they directly experienced of the physical world around them. For perceptual beliefs from direct sensory experience, it’s reasonable to presume our senses aren’t lying. Seeing is, after all, believing. In fact, questioning what you see or hear can get you eaten. For our evolutionary ancestors, it was better to be safe than sorry, especially when considering whether to believe that rustling in the grass is a lion.As a result, we didn’t develop a high degree of skepticism when our beliefs were about things we directly experienced, especially when our lives were at stake.
  • As complex language evolved, we gained the ability to form beliefs about things we hadn’t actually experienced for ourselves–and tended to believe them just as strongly.
  • The bigger risk is in failing to update our beliefs when new information arises
  • we still form beliefs without vetting most of them, and maintain them even after receiving clear, corrective information.
  • The next time you argue with someone about something you believe to be true, step back and ask yourself how you came to this conclusion.

Nobody Really Knows Why We Dream | JSTOR Daily - 0 views

shared by blythewallick on 19 Oct 19 - No Cached
  • In an extensive 2012 literature review, the psychologist Matthew Merced notes that, even though nobody knows for certain why we dream, advances in the technology and techniques of brain research have at least helped explain how we dream. Humans, at least, dream a lot, multiple times a night, and the brain is very active during dream periods. Dreaming must be important, even if it remains mysterious.
  • Early dreaming studies were, frankly, pretty primitive. Researchers would wait for the Rapid Eye Movement (REM) sleep to begin, then wake the subject up and ask about any dreams. Dreaming occurs during non-REM (NREM) sleep as well, but those dreams tend to be less vivid. Now, thanks to PET scans, it is known that large areas of the brain, covering such functions as motor control and sensory processing, all become active during dreams. Chemical changes occur as well, especially during REM: acetylcholine, a neurotransmitter that fires up the brain and forces muscles to contract, ramps up production. Unsurprisingly, areas of the brain controlling awareness and consciousness remain dormant.
  • Assuming there is a purpose, natural selection suggests that dreaming must provide some sort of survival benefit. Why spend energy on involuntary movements and brain activation if nothing is being achieved? One possibility is that dreams are kind of a virtual reality world, a space where humans can safely practice coping with threats (being chased, for example, is pretty common). REM sleep and dreaming may also help process important or traumatic memories. Finally, there is a theory that dreams are a way for the brain to rid itself of information it isn’t using, a sort of “psychic disk cleanup.” According to Merced, any of these explanations could be correct. Sweet dreams to all, humans and octopuses alike!
