I've noticed this trend, too, in a lot of the articles I've posted recently. Something to be aware of: "...we worry that shorter, single-study articles can be poor models of science. ... we are troubled by the link between small study size and publication bias. Theoretically, if several small studies on a topic, each with its own small data set, are sent to publishers, the overall published results should be equivalent to the results of a single large study on that topic using a complete data set. But according to several "meta-studies" that have been conducted, this is often not the case: rather than the small studies' converging on the same result as a large study when published, the small studies give a very different result. ... Small studies are inherently unreliable - larger studies or, better still, multiple studies on the same topic, are more likely to give definitive, accurate results."

"Falsehood flies, and the Truth comes limping after it," Jonathan Swift once wrote. It was hyperbole three centuries ago. But it is a factual description of social media, according to an ambitious and first-of-its-kind study produced by MIT and published Thursday in Science. The massive new study analyzes every major contested news story in English across the span of Twitter's existence-some 126,000 stories, tweeted by 3 million users, over more than 10 years-and finds that the truth simply cannot compete with hoax and rumor. By every common metric, falsehood consistently dominates the truth on Twitter, the study finds: Fake news and false rumors reach more people, penetrate deeper into the social network, and spread much faster than accurate stories. "It seems to be pretty clear [from our study] that false information outperforms true information," said Soroush Vosoughi, a data scientist at MIT who has studied fake news since 2013 and who led this study. "And that is not just because of bots. It might have something to do with human nature."

Recent History of Our Struggle to Make Foreign Languages Core Foreign language study is in the national education Goals 2000, which states: "By the year 2000 all American students will leave grades 4, 8, and 12 having demonstrated competency in challenging subject matter including English, mathematics, science, foreign language, civics and government, arts, history, and geography..."

A new study, conducted by Dr. Catherine Birken, a pediatrician and scientist at the Hospital for Sick Children in Toronto, Ontario, revealed the following: the more time children between the ages of six months and two years spent using handheld screens such as smartphones, tablets and electronic games, the more likely they were to experience speech delays. In the study, which involved nearly 900 children, parents reported the amount of time their children spent using screens in minutes per day at age 18 months. Researchers then used an infant toddler checklist, a validated screening tool, to assess the children's language development also at 18 months. They looked at a range of things, including whether the child uses sounds or words to get attention or help and puts words together, and how many words the child uses. Twenty percent of the children spent an average of 28 minutes a day using screens, the study found. Every 30-minute increase in daily screen time was linked to a 49% increased risk of what the researchers call expressive speech delay, which is using sounds and words. Commenting on the study, Michelle MacRoy-Higgins and Carlyn Kolker, both speech pathologists/therapists and co-authors of "Time to Talk: What You Need to Know About Your Child's Speech and Language Development," offered this advice: interact with your child. The best way to teach them language is by interacting with them, talking with them, playing with them, using different vocabulary, pointing things out to them and telling them stories.

This article discusses the correlation between listening to music and cognition. They mainly used pop music and distinguished their test subjects between extraverts and introverts.

Some studies show that listening to music improves cognitive performance and focus. Certain rhythms and beats can cause shifts in emotion, which can ultimately affect the way that we comprehend things we read. In one of their studies, a controlled group of students studied with music that caused them to feel anxiety while another listened to music that evoked concentration. They also allowed a certain controlled group to listen to their favorite song and actually performed worse on their tests.

Listening to music for relaxation is common among students to counter the effects of stress or anxiety while completing difficult academic tasks. Some studies supporting this technique have shown that background music promotes cognitive performance while other studies have shown that listening to music while engaged in complex cognitive tasks can impair performance.

Listening to music while studying can be helpful for many different reasons. Since music can affect your mood, if you listen to relaxing music it can prevent you from becoming stressed while studying. Music can also help to block out other distractions while studying, especially in busy or loud environments.

"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.

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. :-)

Examining the results and methodology of a large Whorfian study (17 languages), which tested differences if there are differences in cognition between speakers of verb-frame languages (like Spanish, if the "Path is characteristically represented in the main verb or verb root of a sentence") and satellite-frame languages (like English, if the path is "characteristically represented in the satellite and/or preposition"). Important conclusion regarding study methodology: "Strong claims regarding the (in)validity of the Whorfian hypothesis in the encoding of motion events cannot be made on the basis of a limited number of languages or a restricted range of manner and path contrasts." They could have reached opposite conclusions if they only compared certain language pairs.  This is made in contrast with studies by, e.g., Boroditsky, which had relatively small sample sizes.

This article shows how listening to music while studying can impair one's performance while studying.

Listening to music while studying can cause major setbacks in your work

Does the Turkish word küçük (pronounced coo-chook) mean "big" or "small"? If you guessed the latter without knowing the language, you're right-and there may be a cognitive explanation for your instinct. In a study published in Cognition earlier this year, researchers tested people's ability to guess at the meanings of words based on their sounds. The lead researcher of the study, Kaitlyn Bankieris, a cognitive scientist from the University of Rochester, noted, "Our study provides a potential neural grounding for sound symbolism." In linguistics, the idea of "sound symbolism" is that there's an underlying relationship between how words sound and what they mean-and it is sometimes used to support the theory that there's some underlying cross-language meaning that humans are hardwired to attach to certain sounds.

Teenagers use text messaging more than any other mode of communication, so it may be hard to tell. But youngsters who check their phones continually, snap if you interrupt them and are so preoccupied with texting that they skip sleep and don't get their work done may be compulsive texters, a new study says. Overall, girls text compulsively at a far higher rate than boys do. And unlike girls, boys in the study who were compulsive texters were not at risk of doing poorly in school. Dr. Lister-Landman hypothesized that girls' texts may focus more on relationships and be more emotionally laden, causing them anxiety. Studies have shown that communicating by cellphone about problems or negative feelings is more common among young women than among men.

A connection has been found between students who study foreign language and higher SAT scores. For each additional year that students study a foreign language, they are expected to perform better on both the math and language portions of the SAT. Although the SAT is not a direct measure of intelligence by any means, this gives evidence to support that studying a foreign language helps develop both math and English language skills. I would be interested in seeing how foreign language study affects IQ Test scores.

A Liverpool University study found reading poetry lights up both the left part of the brain concerned with language, as well as the right hemisphere, an area that relates to autobiographical memory and emotion. Reading triggers "reappraisal mechanisms" that cause people to reflect on their own experiences in light of what they read. The study might also suggest that word choice and sound are crucial elements in creating beneficial literary experiences: more "challenging" prose and poetry (striking wording/phrasing, complex syntax) sparks far more electrical activity in the brain than more pedestrian translations of those passages.

Mental agility can be boosted by even a short period of learning a language, a study suggests. Tests carried out on students of all ages suggest that acquiring a new language improves a person's attention, after only a week of study. Researchers also found that these benefits could be maintained with regular practice.

(This article was by my college friend, Quinn Eastman, who's a trained scientist and science writer for Emory University.) Listening to metaphors involving arms or legs loops in a region of the brain responsible for visual perception of those body parts, scientists have discovered. The finding, recently published in Brain & Language, is another example of how neuroscience studies are providing evidence for "grounded cognition" - the idea that comprehension of abstract concepts in the brain is built upon concrete experiences, a proposal whose history extends back millennia to Aristotle. When study participants heard sentences that included phrases such as "shoulder responsibility," "foot the bill" or "twist my arm", they tended to engage a region of the brain called the left extrastriate body area or EBA. The same level of activation was not seen when participants heard literal sentences containing phrases with a similar meaning, such as "take responsibility" or "pay the bill." The study included 12 right-handed, English-speaking people, and blood flow in their brains was monitored by functional MRI (magnetic resonance imaging). "The EBA is part of the extrastriate visual cortex, and it was known to be involved in identifying body parts," says senior author Krish Sathian, MD, PhD, professor of neurology, rehabilitation medicine, and psychology at Emory University. "We found that the metaphor selectivity of the EBA matches its visual selectivity." The EBA was not activated when study participants heard literal, non-metaphorical sentences describing body parts. "This suggests that deep semantic processing is needed to recruit the EBA, over and above routine use of the words for body parts," Sathian says. Sathian's research team had previously observed that metaphors involving the sense of touch, such as "a rough day", activate a region of the brain important for sensing texture. In addition, other researchers have shown t

Recently, people have been returning to writing basics: handwriting, notebooks, pens, paper, and stationary. While technology can certainly provide an edge for certain tasks, digital overload, addiction, and distraction are growing concerns. many studies indicate that multitasking is bad for us and makes our brains more scattered. In contrast, several studies suggest that pen and paper have an edge over the keyboard. In three studies, researchers found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. Those who took written notes had better comprehension and retention of material because they had to mentally process information rather than type it verbatim. And, another study, published in the Journal of Applied Cognitive Psychology, showed that people who doodle can better recall dull information. Writing it down also sparks innovation. Being innovative and creative is about "getting your hands dirty" a feeling that is lacking when you use technology or gadgets, says Arvind Malhotra, a professor at the University of North Carolina Kenan-Flagler Business School."Research has also shown that tactile sensory perceptions tend to stimulate parts of the brain that are associated with creativity. So, touch, feel and the sensation you get when you build something physical has also got a lot to do with creativity," he says.

"Web addicts have brain changes similar to those hooked on drugs or alcohol, preliminary research suggests. ... Dr Hao Lei and colleagues write in Plos One: 'Overall, our findings indicate that IAD has abnormal white matter integrity in brain regions involving emotional generation and processing, executive attention, decision making and cognitive control.' ... Prof Gunter Schumann, chair in biological psychiatry at the Institute of Psychiatry at King's College, London, said similar findings have been found in video game addicts. ... further studies with larger numbers of subjects were needed to confirm the findings."

A study conducted by neuroscientists from Northwestern University showed that the adolescent brain still has a considerable amount of neuroplasticity. The study also verified that music students developed improvements in auditory processing, which is crucial for verbal processing.

Schizophrenia is a very disabling psychiatric illness affecting about 2 to 3 million Americans. Contrary to popular perception, it has nothing to do with a "split personality." Schizophrenia is a chronic brain disorder involving "positive" and "negative" symptoms. Positive symptoms include hallucinations (hearing voices or seeing visions that aren't real), delusions (fixed false beliefs), and disorganized thinking or speech. A recent study in the Archives of General Psychiatry by Paul Grant, Aaron Beck, and their colleagues found that a modified version of cognitive-behavioral therapy (CBT), a specific type of talk therapy, can produce clinically significant improvement in patients with schizophrenia. Importantly, significant improvement was seen in certain negative symptoms-apathy/avolition (lack of drive)-as well as in positive symptoms. These results are impressive, especially considering that the participants had been ill for an average of 18 years and suffered from severe symptoms. In this study, study participants were divided into two groups. One group received CBT in addition to "standard treatment," which included treatment with antipsychotic medications. The other group received standard treatment alone. CBT has been shown to be effective in a variety of psychiatric illnesses. It uses pragmatic techniques to help a person correct inaccurate or dysfunctional thoughts and emotions by promoting critical comparison of those thoughts with observable facts. For example, if a person believes that he/she is "doing absolutely nothing," one CBT technique would be to encourage the person to keep a detailed diary of daily activities. The therapist would later review this diary with the patient and facts would be compared to perceptions. Homework assignments would include strategies to increase productive activities. In the study mentioned above, the researchers focused CBT "on identifying and promoting concrete goals for improving quality of life and
