“Sometimes baby talk is associated with nonsense words and sounds and even distorts sounds of words, providing inaccurate models of the infants and developing child, this is not encouraged,” says Kathleen Czuba, speech language therapist, Loyola University Health System. “Research in the field of child development and speech and language acquisition instead recommends the use of ‘parentese.’ This type of speech has been shown to positively support the development of speech and language.”

“Challenges with speech and language are likely to have an impact on the child’s overall development including in the areas of socials skills, academia and even can impact a child’s behavior,” says Kathleen Czuba, speech-language therapist, Loyola University Health System. “The earlier a child's speech and language problems are identified and treated, the less likely it is that problems will persist or get worse.”

Studies have shown that individuals with hearing loss or who are listening to degraded speech – think of a loud room -- have greater difficulty remembering and processing the spoken information than individuals who heard more clearly. Now researchers are investigating whether listening to accented speech similarly affects the brain's ability to process and store information. Their preliminary results suggest that foreign-accented speech, even when intelligible, may be slightly more difficult to recall than native speech.

A McGill University/UQAM research team has discovered that 6-month-old infants appear to be much more interested in listening to other babies than they are in listening to adults. The researchers believe that an attraction to infant speech sounds may help to kick start and support the crucial processes involved in learning how to talk.

When it comes to rewards and punishments, which is more effective — the carrot or the stick? A simple experiment devised at Washington University in St. Louis suggests that punishments are more likely to influence behavior than rewards. The results, which stem from a study involving 88 students at the university, are available online in the journal Cognition.

The University of Washington study is among the first to identify structural brain differences between children with the two learning disorders and between those children and typical language learners. Researchers say the findings prove that using a single category of learning disability to qualify for special education services is not scientifically supported.

Epigenetic marks on our DNA account for how all cells in the body have the same DNA sequence, inherited from our parents, but nonetheless there are hundreds of different cell types. The body uses epigenetics as its principal control system, to increase or decrease the expression of our genes, and epigenetic processes are known to be important in memory and other aspects of brain function. The new research used umbilical cord tissue collected at birth and identified epigenetic marks in a key brain development gene called HES1 that were linked to the child’s ability to learn and their cognitive performance at ages 4 and 7 years. The findings in two groups of children in Southampton, UK, were accompanied by additional findings in children from Singapore that HES1 epigenetic marks at birth were associated with aspects of socially disruptive behaviour that have previously been linked with a reduced school performance.

Mood disorder research suggests that early life stress may cause excess serotonin release, resulting in a serotonin deficit where the brain needs it most. The data suggest a reason why SSRI medications may fail in many patients, and why depressed patients may benefit from strategic SSRI-augmenting treatment approaches.

Georgia Tech study challenged younger and older people to look at faces at names while either listening to non-lyrical music or nothing at all. The college-aged participants had no problems - the music didn't affect their performance. But the older adults remembered 10 percent fewer names when listening to background music or musical rain (as compared to silence).
