Research about the association between music and speech. Tonal languages, such as Mandarin, support theories of language developing out of a "protolanguage" comprised of sounds that were more similar to tones than words.

Including answers to questions such as: - Can you walk us through the logic Watson would go through to answer a question such as, "The antagonist of Stevenson's Treasure Island." (Who is Long John Silver?) - ...I found myself wondering whether what it does is really natural language processing, or something more akin to word association... does Watson really need to understand syntax and meaning to just search its database for words and phrases associated with the words and phrases in the clue?

"The current, long-standing theory suggests that children learn their first words through a series of associations; they associate words they hear with multiple possible referents in their immediate environment....A small set of psychologists and linguists, including members of the Penn team, have long argued that the sheer number of statistical comparisons necessary to learn words this way is simply beyond the capabilities of human memory.... rich interactions with children-and patience-are more important than abstract picture books and drilling."

A new longitudinal study, led by Mary E. Brushe, a researcher at the Telethon Kids Institute at the University of Western Australia, gathered data from 220 families across South Australia, Western Australia and Queensland with children who were born in 2017. Once every six months until they turned 3, the children wore T-shirts or vests that held small digital language processors that automatically tracked their exposure to certain types of electronic noise, as well as language spoken by the child, the parent or another adult. The researchers were particularly interested in three measures of language: words spoken by an adult, child vocalizations and turns in the conversation. They modeled each measure separately and adjusted the results for age, sex and other factors, such as the mother's education level and the number of children at home. Researchers found that at almost all ages, increased screen time squelched conversation. When the children were 18 months old, each additional minute of screen time was associated with 1.3 fewer child vocalizations, for example, and when they were 2 years old, an additional minute was associated with 0.4 fewer turns in conversation. The strongest negative associations emerged when the children were 3 years old - and were exposed to an average of 2 hours 52 minutes of screen time daily. At this age, just one additional minute of screen time was associated with 6.6 fewer adult words, 4.9 fewer child vocalizations and 1.1 fewer turns in conversation.

Novelist Kurt Vonnegut once opined, "There is no reason why the simple shapes of stories can't be fed into computers. They are beautiful shapes." Thanks to new text-mining techniques, this has now been done. Researchers at the University of Vermont's Computational Story Lab have analysed over 1,700 English novels to reveal six basic story types - you could call them archetypes - that form the building blocks for more complex stories. They are: 1. Rags to riches - a steady rise from bad to good fortune 2. Riches to rags - a fall from good to bad, a tragedy 3. Icarus - a rise then a fall in fortune 4. Oedipus - a fall, a rise then a fall again 5. Cinderella - rise, fall, rise 6. Man in a hole - fall, rise The researchers used sentiment analysis to get the data - a statistical technique often used by marketeers to analyse social media posts in which each word is allocated a particular 'sentiment score', based on crowdsourced data. Depending on the lexicon chosen, a word can be categorised as positive (happy) or negative (sad), or it can be associated with one or more of eight more subtle emotions, including fear, joy, surprise and anticipation. For example, the word 'happy' is positive, and associated with joy, trust and anticipation. The word 'abolish' is negative and associated with anger. Do sentiment analysis on all the words in a novel, poem or play and plot the results against time, and it's possible to see how the mood changes over the course of the text, revealing a kind of emotional narrative. While not a perfect tool - it looks at words in isolation, ignoring context - it can be surprisingly insightful when applied to larger chunks of text

In this study, we address the communication technologies individuals within romantic relationships are using to communicate with one another, the frequency of use, and the association between the use of these technologies and couple's positive and negative communication.Participants consisted of individuals involved in a serious, committed, heterosexual relationship. The Relationship Evaluation Questionnaire instrument was used to assess a variety of relationship variables. The majority of individuals within the study frequently used cell phones and text messaging to communicate with their partner, with ' ' expressing affection ' ' being the most common reason for contact. Younger individuals reported using all forms of media (except for e-mail) more frequently than older participants. Relationship satisfaction did not predict specific use of media but predicted several reasons for media use. Additional analyses revealed that text messaging had the strongest association with individuals ' positive and negative communication within their relationships. Specifically, text messaging to express affection, broach potentially confrontational subjects, and to hurt partners were associated with individuals' view of positive and negative communication within their relationship. Implications of the results are discussed.

Abstract: Self-affirmation theory posits that people are motivated to maintain a positive self-view and that threats to perceived self-competence are met with resistance. When threatened, self-affirmations can restore self-competence by allowing individuals to reflect on sources of self-worth, such as core values. Many questions exist, however, about the underlying mechanisms associated with self-affirmation. We examined the neural mechanisms of self-affirmation with a task developed for use in a functional magnetic resonance imaging environment. Results of a region of interest analysis demonstrated that participants who were affirmed (compared with unaffirmed participants) showed increased activity in key regions of the brain's self-processing (medial prefrontal cortex + posterior cingulate cortex) and valuation (ventral striatum + ventral medial prefrontal cortex) systems when reflecting on future-oriented core values (compared with everyday activities). Furthermore, this neural activity went on to predict changes in sedentary behavior consistent with successful affirmation in response to a separate physical activity intervention. These results highlight neural processes associated with successful self-affirmation, and further suggest that key pathways may be amplified in conjunction with prospection.

Brain-imaging studies have shown that music activates many diverse parts of the brain, including an overlap in where the brain processes music and language. Brains of people exposed to even casual musical training have an enhanced ability to generate the brain wave patterns associated with specific sounds, be they musical or spoken, said study leader Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University in Illinois. Musicians have subconsciously trained their brains to better recognize selective sound patterns, even as background noise goes up. In contrast, people with certain developmental disorders, such as dyslexia, have a harder time hearing sounds amid the din. Musical experience could therefore be a key therapy for children with dyslexia and similar language-related disorders. Harvard Medical School neuroscientist Gottfried Schlaug has found that stroke patients who have lost the ability to speak can be trained to say hundreds of phrases by singing them first. Schlaug demonstrated the results of intensive musical therapy on patients with lesions on the left sides of their brains, those areas most associated with language. Before the therapy, these stroke patients responded to questions with largely incoherent sounds and phrases. But after just a few minutes with therapists, who asked them to sing phrases and tap their hands to the rhythm, the patients could sing "Happy Birthday," recite their addresses, and communicate if they were thirsty. "The underdeveloped systems on the right side of the brain that respond to music became enhanced and changed structures," Schlaug said at the press briefing.

Is social media good for you, or bad? Well, it's complicated. A UC San Diego study of 12 million Facebook users suggests that using Facebook is associated with living longer -- when it serves to maintain and enhance your real-world social ties. Those on Facebook with highest levels of offline social integration -- as measured by posting more photos, which suggests face-to-face social activity -- have the greatest longevity. Online-only social interactions, like writing wall posts and messages, showed a nonlinear relationship: Moderate levels were associated with the lowest mortality. Facebook users who accepted the most friendships also lived longest.

Brain imaging studies have explored the neural mechanisms of recovery in adults following acquired disorders and, more recently, childhood developmental disorders. However, the neural systems underlying adult rehabilitation of neurobiologically based learning disabilities remain unexplored, despite their high incidence. Here we characterize the differences in brain activity during a phonological manipulation task before and after a behavioral intervention in adults with developmental dyslexia. Phonologically targeted training resulted in performance improvements in tutored compared to nontutored dyslexics, and these gains were associated with signal increases in bilateral parietal and right perisylvian cortices. Our findings demonstrate that behavioral changes in tutored dyslexic adults are associated with (1) increased activity in those left-hemisphere regions engaged by normal readers and (2) compensatory activity in the right perisylvian cortex. Hence, behavioral plasticity in adult developmental dyslexia involves two distinct neural mechanisms, each of which has previously been observed either for remediation of developmental or acquired reading disorders.

This month, the journal Pediatrics published a study that used functional magnetic resonance imaging to study brain activity in 3-to 5-year-old children as they listened to age-appropriate stories. The researchers found differences in brain activation according to how much the children had been read to at home. Children whose parents reported more reading at home and more books in the home showed significantly greater activation of brain areas in a region of the left hemisphere called the parietal-temporal-occipital association cortex. This brain area is "a watershed region, all about multisensory integration, integrating sound and then visual stimulation," said the lead author, Dr. John S. Hutton, a clinical research fellow at Cincinnati Children's Hospital Medical Center. This region of the brain is known to be very active when older children read to themselves, but Dr. Hutton notes that it also lights up when younger children are hearing stories. What was especially novel was that children who were exposed to more books and home reading showed significantly more activity in the areas of the brain that process visual association, even though the child was in the scanner just listening to a story and could not see any pictures. "When kids are hearing stories, they're imagining in their mind's eye when they hear the story," said Dr. Hutton. "For example, 'The frog jumped over the log.' I've seen a frog before, I've seen a log before, what does that look like?" The different levels of brain activation, he said, suggest that children who have more practice in developing those visual images, as they look at picture books and listen to stories, may develop skills that will help them make images and stories out of words later on. "It helps them understand what things look like, and may help them transition to books without pictures," he said. "It will help them later be better readers because they've developed that part of the brain

Doctors at Beth Israel Deaconess Medical Center in Boston, Massachusetts, are treating stroke patients who have little or no spontaneous speech by associating melodies with words and phrases. "Music, and music-making, is really a very special form of a tool or an intervention that can be used to treat neurological disorders, said Dr. Gottfried Schlaug, associate professor of neurology at Beth Israel and Harvard University.

"Sustained changes in the region of the brain associated with cognitive function and emotional control were found in young adult men after one week of playing violent video games ... The results showed that after one week of violent game play, the video game group members showed less activation in the left inferior frontal lobe during the emotional Stroop task and less activation in the anterior cingulate cortex during the counting Stroop task."

Actually, there are some studies just about emotional Stroop tests that sound similar to the one in the violent video games study. This looks like a good presentation about how emotional Stroop tests work: http://frank.mtsu.edu/~sschmidt/Cognitive/Emotion1.pdf This one talks about why those Stroop tests work: "In this task, participants name the colors in which words are printed, and the words vary in their relevance to each theme of psychopathology.The authors review research showing that patients are often slower to name the color of a word associated with concerns relevant to their clinical condition." - http://brainimaging.waisman.wisc.edu/~perlman/papers/stickiness/WilliamsEmoStroop1996.pdf This is a meta-analysis of emotional Stroop test studies that describes (actually, it's critical of) how such studies are done: http://www.psych.wustl.edu/coglab/publications/LarsenMercerBalota2006.pdf

Thanks, Ryan! I will take a look at these.

"Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia ... Less day dreaming has been associated with increased happiness levels ... experienced meditators had decreased activity in areas of the brain called the default mode network, which has been implicated in lapses of attention and disorders such as anxiety, attention deficit and hyperactivity disorder, and even the buildup of beta amyloid plaques in Alzheimer's disease."

"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."

The writer discusses the benefits that one can gain from learning a foreign language in terms of money, and how even though the money gained is initially small, over time as those small earnings compound, the money gained from being bilingual can add up to about $100,000, depending on the language. He also discusses the benefits of investing more in foreign language so that countries can get more return and cut down on losses associated with not having enough language diversity within their native populations.

"The idea of assigning colors to Republicans and Democrats has been around for more than a century, though the red-blue color scheme has only been fixed relatively recently.... [In the 1900s] Democrats may have wanted to appropriate the positive connotations of blue (as in true-blue) at a time when red was becoming associated with revolutionaries and anarchists." First contemporary usage on TV in 2000, by Tim Russert.

"Most people implicitly associate positive ideas with "right" and negative ideas with "left"....The meanings of words in English, Dutch, and Spanish are related to the way people type them on the QWERTY keyboard. Words with more right-hand letters are rated as more positive in emotional valence than words with more left-hand letters, consistent with right-handers' tendency to implicitly associate "good" with "right.""
