One significant concern that pilots have about cockpit auditory warnings is that the signals presently used lack a sense of priority. The relationship between auditory warning sound parameters and perceived urgency is, therefore, an important topic of enquiry in aviation psychology. The present investigation examined the relationship among subjective assessments of urgency, reaction time, and brainwave activity with three auditory warning signals. Subjects performed a tracking task involving automated and manual conditions, and were presented with auditory warnings having various levels of perceived and situational urgency. Subjective assessments revealed that subjects were able to rank warnings on an urgency scale, but rankings were altered after warnings were mapped to a situational urgency scale. Reaction times differed between automated and manual tracking task conditions, and physiological data showed attentional differences in response to perceived and situational warning urgency levels. This study shows that the use of physiological measures sensitive to attention and arousal, in conjunction with behavioural and subjective measures, may lead to the design of auditory warnings that produce a sense of urgency in an operator that matches the urgency of the situation.

This article talked about how language has an influence on how we perceive time. Researchers first found this to be true in bilinguals, as they are capable of code-switching. After, researchers were able to identify that each language perceives time in different durations. Also, bilingual speakers, when switching between languages, use the specific time duration measure of that language.

Some languages, like Swedish and English, describe time as length. Other languages, like Spanish and Greek, describe time as size. These differences in language lead to differences in how people perceive time. Spanish-Swedish bilinguals' perception of time changes depending on the language they are thinking in.

This article explores how dogs perceive human language and whether tone of voice matters. Through this experiment, it was discovered that dogs respond positively to a positive tone of voice and neutrally to a neutral tone of voice. However, if the dog was reprimanded in a positive tone of voice, the dog would perceive that as a praise. In terms of language evolution, it suggests that the ability to "process meaning and emotion in different parts of the brain and tie them together is not uniquely human."

The German poet Christian Morgenstern once said that "all seagulls look as though their name were Emma." Though Morgenstern was known for his nonsense poetry, there was truth in his suggestion that some linguistic labels are perfectly suited to the concepts they denote. Similar to what we've learned about metaphors, labels and names influence how we think and behave. Studies suggest as soon as you label a concept, you change how people perceive it (aka the Heisenberg principle.) Words evoke images such as 'bouba' and 'kiki' from James Geary's TedTalk, directional concepts such as are "north" with up and "south" with down, and simplicity of pronunciation and spelling all affects how one perceives another.

The culture of Okinawa, Japan is quite distinct from other Japanese islands. It became a part of Japan in 1879, but has a strong American influence because of three decades of military occupation following WWII. Today, 20% of the island is made up of over 30 U.S. military bases. This history has resulted in the near extinction of the Okinawan language, called Uchinaguchi, which was systematically suppressed when the island was annexed by Japan. Because of ubiquitous U.S. presence, Okinawans perceive more of a need for English competence than for learning the language of their ancestors. Once the U.S. ceded control of the island back to Japan in the 1970's, the island underwent changes that many Okinawans perceived as another occupation, but this time instead of U.S. military projects, Japanese business took over the island. Japanese power over Okinawa can even be seen in the language politics: Uchinaguchi was long considered a dialect of Japanese despite the two languages having less than 60% in common. In 2009 UNESCO recognized Okinawan as its own language along with five others spoken in the region, all of which are endangered. Native speakers are aging and dying off. Efforts to revitalize Uchinaguchi on the island are regularly stifled by the local government's indifference towards the language. Nonetheless, the language is praised for its folkloric value and is featured in local theater. Some schools offer language classes, such as Okinawa Christian University. Because Uchinaguchi is a low priority in the political field, the cultural field is the site of language revitalization and resistance to its extinction. One benefit of promoting the language through culture is that, unlike the government, the culture can have influence overseas.

This Scientific American blog article provides a handy run-down of research findings re: music's effect on the brain, including 1. Musicians are better able to process foreign languages because of their ability to hear differences in pitch, and have incredible abilities to detect speech in noise. Even those w/ a few years of music training showed more robust neural processing of sounds. Music "tones auditory fitness", critical for perceiving speech and distinguishing, recognizing and processing conversation in noisy environments. 2. Musical training and education may confer linguistic, mathematical, and spatial benefits, and promote social development/"team player" capacities.

As anti-Muslim rhetoric increases, American officials are cautioning that it could validate extremists' perceptions that Americans are waging a war on Islam. New research from Northwestern University's Kellogg School of Management lends credence to this fear. Research conducted by Ntour Kteily (Northwestern assistant professor of management and organizations), Gordon Hodson (Canada's Brock University), and Emile Bruneau (U. Penn. neuroscientist) shows that feeling dehumanized by another group can lead you to dehumanize that group in return, which can increase support for aggressive actions against them. Meaning, if Americans think that Muslims see them as savages, Americans will be more likely to return the "favor," perceiving Muslims to be savages. And both groups will be more likely to support aggressive acts-like drone strikes or torture-against the other.

This illustrated video from Mental Floss explores word doubles in English: a phenomenon which springs from Germanic and Latin linguistic influences. The video also explores why Latinate words are often perceived as being more elegant and erudite than their Anglo-Saxon (Germanic) counterparts.

ABSTRACT: The present investigation examined the impact of bicultural identity, bilingualism, and social context on the psychological adjustment of multicultural individuals.......We concluded that, in the process of managing multiple cultural environments and group loyalties, bilingual competence, and perceiving one's two cultural identities as integrated are important antecedents of beneficial psychological outcomes.

"Tweenage girls who spend endless hours watching videos and multitasking with digital devices tend to be less successful with social and emotional development ... The girls' answers showed that multitasking and spending many hours watching videos and using online communication were statistically associated with a series of negative experiences: feeling less social success, not feeling normal, having more friends whom parents perceive as bad influences and sleeping less. ... The survey findings are bad news, given that the 8 to 12 age range is critical for the social and emotional development of girls, and because children are becoming active media consumers at an ever-younger age. ... Higher levels of face-to-face communication were associated with greater social success, greater feelings of normalcy, more sleep and fewer friends whom parents judged to be bad influences. Children learn the difficult task of interpreting emotions by watching the faces of other people, Pea said. ... For the negative effects of online gorging, "There seems to be a pretty powerful cure, a pretty powerful inoculant, and that is face-to-face communication," Nass said."

Can babies learn to read? While parents use DVDs and other media in an attempt to teach their infants to read, these tools don't instill reading skills in babies, a study by researchers at New York University's Steinhardt School of Culture, Education, and Human Development has found. In their study, which appears in the Journal of Educational Psychology, the researchers examined 117 infants, aged nine to 18 months, who were randomly assigned to treatment and control groups. Children in the treatment condition received a baby media product, which included DVDs, word and picture flashcards, and flip books to be used daily over a seven-month period; children in the control condition did not receive these materials from the researchers. Over the course of seven months, the researchers conducted a home visit, four laboratory visits, and monthly assessments of language development. To test children's emerging skills in the laboratory, the researchers examined the capacity to recognize letter names, letter sounds, vocabulary, words identified on sight, and comprehension. A combination of eye-tracking tasks and standardized measures were used to study outcomes at each stage of development. Using a state-of-the art eye-tracking technology, which follows even the slightest eye movements, the researchers were able to closely monitor how the infants distributed their attention and how they shifted their gaze from one location to another when shown specific words and phrases. No discernible differences were observed between the results of the experimental group vs. the control; yet parents of the infants in the experimental group perceived that their children were, in fact, acquiring words. :-)

How different aspects of speech, such as intonation and dynamics, affect how we perceive other people's personalities

"Thoughtful questions often prompt thoughtful analysis and recently a series of questions from a reader regarding 'micro-expressions' had such an effect on me. His questions made me stop and think about how the public perceives 'micro expressions' and their significance in our overall understanding of body language, and more importantly, their relevance in detecting deception."

Our words shape the way we perceive, describe, and remember things.

"An array of electrodes receiving input from a non-tactile information source (a camera, for instance) applies small, controlled, painless currents...to the skin at precise locations according to an encoded pattern. The encoding of the electrical pattern essentially attempts to mimic the input that would normally be received by the non-functioning sense. ... When the encoded pulses are applied to the skin, the skin is actually receiving image data." "After training in laboratory tests, blind subjects were able to perceive visual traits like looming, depth, perspective, size and shape."

Just having a feminine voice means you're probably not as capable at your job. At least, studies suggest, that's what many people in the United States think. There's a gender bias in how Americans perceive feminine voices: as insecure, less competent and less trustworthy.

This article reminds me of the "Singing Neanderthals" reading that we did. Perhaps whales, like babies, hear tones instead of actual words and can also perceive emotions of other whales they communicate with. If this is so, would this 'tone communication' be considered a language in of itself?

A really interesting study combining linguistics and behavioral economics. "To judge a risk more clearly, it may help to consider it in a foreign language: A series of experiments on more than 300 people from the U.S. and Korea found that thinking in a second language reduced deep-seated, misleading biases that unduly influence how risks and benefits are perceived."

It's not just what you say, it's the way that you say it. The sound of our voices, including its pitch, accent and inflection, has all sorts of subtle effects on how we are perceived by other people. This article lists 10 ways that our voices influence others' conception of us and provides links to the relevant studies.
