Dr. Nick Perham, a lecturer in the School of Health Sciences at the University of Wales Institute, Cardiff, conducted a 2010 study, "Can preference for background music mediate the irrelevant sound effect?", that shows how music can interfere with short-term memory performance. Perham had subjects conduct a certain task, in this case recalling a series of numbers, while listening to different kinds of background music. If sound exhibits acoustical variations, or what Perham calls an "acute changing-state," performance is impaired. Steady-state sounds with little acoustical variation don't impair performance nearly as much. Perham asked his subjects how they thought they performed when exposed to different tastes in music. Each reported performing much worse when listening to disliked music, although the study's results showed no difference. However, Perham found no distinction in performance, regardless of whether the music was liked or disliked: both were "worse than the quiet control condition. Both impaired performance on serial-recall tasks." The interviewer queried how curious how prevalent serial-recall is in everyday life, and if one could get by without developing this skill. Unlikely, Perham says, as one would have tremendous difficulty recalling phone numbers, doing mental arithmetic, and even learning languages. "Requiring the learning of ordered information has also been found to underpin language learning. If you consider language, learning syntax of language, learning the rules that govern how we put a sentence together, all of these require order information . . . " Perham says.

This article talks about connections between kids with ADHD and communications impairments.

This article is about how the auditory skills of hearing impaired children is affected by the amount of music and singing is in their live. A study conducted by a University in Helsinki measured different things connected to music and singing to brain responses in children with cochlear implants.

'By studying language in people with aphasia, we can try to accomplish two goals at once: we can improve our clinical understanding of aphasia and get new insights into how language is organized in the mind and brain,' said Daniel Mirman, Professor of Psychology at Drexel University. Mirman is lead author of a new study which examined data from 99 people who had persistent language impairments after a left-hemisphere stroke. In the first part of the study, the researchers collected 17 measures of cognitive and language performance and used a statistical technique to find the common elements that underlie performance on multiple measures. Researchers found that spoken language impairments vary along four dimensions or factors: 1. Semantic Recognition: difficulty recognizing the meaning or relationship of concepts, such as matching related pictures or matching words to associated pictures. 2. Speech Recognition: difficulty with fine-grained speech perception, such as telling "ba" and "da" apart or determining whether two words rhyme. 3. Speech Production: difficulty planning and executing speech actions, such as repeating real and made-up words or the tendency to make speech errors like saying "girappe" for "giraffe." 4. Semantic Errors: making semantic speech errors, such as saying "zebra" instead of "giraffe," regardless of performance on other tasks that involved processing meaning. In the second part of the study, researchers mapped the areas of the brain associated with each of the four dimensions identified above.

Schizophrenia causes a disturbed sense of continuity of time

Excellent study. "While it has long been recognized that certain areas in the brain's left hemisphere enable us to understand and produce language, scientists are still figuring out exactly how those areas divvy up the highly complex processes necessary to comprehend and produce language. ... Two brain areas called Broca's region and Wernicke's region serve as the main computing hubs underlying language processing, with dense bundles of nerve fibers linking the two ... Working with patients suffering from language impairments because of a variety of neurodegenerative diseases, Wilsons' team used brain imaging and language tests to disentangle the roles played by the two pathways. ... The study marks the first time it has been shown that upper and lower tracts play distinct functional roles in language processing."

While the left hemisphere of the brain is where the processing and understanding of language is, different sections of the brain control different parts of language. Two separate areas of the brain control the ability to remember and understand specific words, and the other controls how we construct sentences and make sense of them. If one of these sections is damaged, the other can still work properly, so it is possible to be able to remember words and what they mean but not know how to create sentences.

Stephen Wilson, an associate professor in the University of Arizona's Department of Speech, Language, and Hearing Sciences, studied the upper and lower white-matter connecting pathways between Broca's region and Wernicke's region: the two areas of the brain that are hubs for language processing. Brain imaging and language tests were used to examine patients suffering from language impairments caused by neurodegeneration. Wilson discovered the pathways have distinct functions. Damage to the lower pathway affects lexicon and semantics: "You forget the name of things, you forget the meaning of words. But surprisingly, you're extremely good at constructing sentences." Conversely, damage to the upper pathway creates problems in syntactic processing and figuring out the relationship between words in a sentence.

Language isn't found in just one part of the brain but rather in separate individual parts that are responsible for different aspects of language. Neurodegentive diseases that target specific areas of the brain affecting language, only have a partial effect on the patients ability to understand and communicate.

Considering the cognitive and linguistic complexity of discourse production, it is expected that individuals with traumatic brain injury (TBI) should face difficulties in this task. Therefore, clinical examination of discourse has become a useful tool for studying and assessment of communication skills of people suffering from TBI.

Systems Neuroscience Philadelphia, PA (Scicasts) - The exchange of words, speaking and listening in conversation, may seem unremarkable for most people, but communicating with others is a challenge for people who have aphasia, an impairment of language that often happens after stroke or other brain injury.

"...when the exact same material is presented in both media, there is no measurable difference in student performance. ... However, there are some subtle distinctions that favor print, which may matter in the long run. ... First, more repetition was required with computer reading to impart the same information. "Second, the book readers seemed to digest the material more fully. ... seemingly irrelevant factors like remembering whether you read something at the top or the bottom of page - or whether it was on the right or left hand side of a two-page spread or near a graphic - can help cement material in mind. ... spatial context may be particularly important because evolution may have shaped the mind to easily recall location cues so we can find our way around ... E-books, however, provide fewer spatial landmarks than print."

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

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.

In a group of internationally adopted children with cleft lip and/or palate, speech at age five is impaired compared to a corresponding group of children born in Sweden, a study shows. The adopted children also need more extensive surgery, which may be due to their surgical interventions taking place later in life.

This experiment dealt with patients who have Aphasia (an impairment of language due to a stroke or brain injury) and mapped out the brain to see what areas of the brain are affected and how their brains differ.

While this article is directed towards teachers, students can leverage this information to their advantage. Employ the following five strategies to aid retention: 1. Teach a friend. When students explain what they've learned to peers, fading memories are reactivated, strengthened, and consolidated. This strategy not only increases retention but also encourages active learning (Sekeres et al., 2016). 2. The spacing effect: Instead of covering a topic and then moving on, revisit key ideas throughout the school year. Research shows that students perform better academically when given multiple opportunities to review learned material. For example, teachers can quickly incorporate a brief review of what was covered several weeks earlier into ongoing lessons, or use homework to re-expose students to previous concepts (Carpenter et al., 2012; Kang, 2016). 3. Frequent practice tests: Akin to regularly reviewing material, giving frequent practice tests can boost long-term retention and, as a bonus, help protect against stress, which often impairs memory performance. Breaking down one large high-stakes test into smaller tests over several months is an effective approach (Adesope, Trevisan, & Sundararajan, 2017; Butler, 2010; Karpicke, 2016). 4. Interleave concepts: Instead of grouping similar problems together, mix them up. Solving problems involves identifying the correct strategy to use and then executing the strategy. When similar problems are grouped together, students don't have to think about what strategies to use-they automatically apply the same solution over and over. Interleaving forces students to think on their feet, and encodes learning more deeply (Rohrer, 2012; Rohrer, Dedrick, & Stershic, 2015). 5. Combine text with images: It's often easier to remember information that's been presented in different ways, especially if visual aids can help organize information. For example, pairing a list of countries occupied by German forces during World War II wi

This research article was published to the Journal of Experimental Psychology, but this experiment did include linguistics. The experiments purpose was to see if more engaged working memory could quickly determine whether a word was really a word, thus the effect of the working memory on semantic meaning. They found that a high working memory load impaired the prime and task efficiency.

Scientists are reporting in the journal Science that they have identified specialized brain cells that help us understand what a speaker really means. These cells do this by keeping track of changes in the pitch of the voice. "We found that there were groups of neurons that were specialized and dedicated just for the processing of pitch," says Dr. Eddie Chang, a professor of neurological surgery at the University of California, San Francisco. Chang says these neurons allow the brain to detect "the melody of speech," or intonation, while other specialized brain cells identify vowels and consonants. "Intonation is about how we say things," Chang says. "It's important because we can change the meaning, even - without actually changing the words themselves." The identification of specialized cells that track intonation shows just how much importance the human brain assigns to hearing, says Nina Kraus, a neurobiologist who runs the Auditory Neuroscience Laboratory at Northwestern University. "Processing sound is one of the most complex jobs that we ask our brain to do," Kraus says. And it's a skill that some brains learn better than others, she says. Apparently, musicians, according to a study conducted by Kraus, are better than non-musicians at recognizing the subtle tonal changes found in Mandarin Chinese. On the other hand, recognizing intonation is a skill that's often impaired in people with autism, Kraus says. "A typically developing child will process those pitch contours very precisely," Kraus says. "But some kids on the autism spectrum don't. They understand the words you are saying, but they are not understanding how you mean it." The new study suggests that may be because the brain cells that usually keep track of pitch aren't working the way they should.

Alcohol consumption, in small amounts, can improve a person's ability to speak a second language. It was also focused on how people who drank the alcohol had better pronunciation in the second language. Although a small amount of alcohol can be beneficial to using language, it is actually reversed if too much is consumed.

This article outlines a study done that found that low levels of alcohol intake can improve bilingual speaker's use of their second language. Although it may seem alcohol would impair language ability because of the executive functions needed when speaking, alcohol lowers social anxiety and increases confidence - which is helpful when learning to speak a second language.
