Babies are adept at getting what they need -- including an education. New research shows that babies organize mothers' verbal responses, which promotes more effective language instruction, and infant babbling is the key.

Chances are someone in your life causes a lot of tension and stress. Difficult relationships are common and hard to evade. New research suggests that difficult people are likely to be found in contexts where people have less freedom to pick and choose their associates. Often it's family and co-workers - people you're stuck with, either because you need them or because you can't ignore them -- making it difficult to cut the cord.

Despite increasing numbers of underrepresented minority (URM) trainees in the biomedical sciences, there is a persistent shortage of URM faculty who are involved in basic biomedical research at medical schools. Investigators examined the entire training pathway of potential faculty candidates to identify points of greatest loss of URM trainees. Two key points of loss: during undergraduate education and in transition from postdoctoral fellowship to tenure-track faculty.

A new study provides one of the first looks inside the infant's brain to show where the sense of touch is processed -- not just when a baby feels a touch to the hand or foot, but when the baby sees an adult's hand or foot being touched, as well. Researchers say these connections help lay the groundwork for the developmental and cognitive skills of imitation and empathy.

Most people think of vision as simply a function of information the eye gathers. For cognitive psychologists vision is a little more complicated than that. One researcher now faces head-on the notion that her experimental subjects have been victims of a psychological phenomenon called response bias.

Dyslexia is a learning difficulty which affects the ability to adopt the automatic reflexes needed to read and write. Several studies have sought to identify the source of the problems encountered by individuals with dyslexia when they read. Little attention, however, has been paid to the mechanisms involved in writing. Researchers have recently looked at the purely motor aspects of writing in children diagnosed with dyslexia. Their results show that orthographic processing in children with dyslexia is so laborious that it can modify or impair writing skills, despite the absence of dysgraphia in these children.

In three separate studies with over 350 five- to 12-year-old white children, researchers found that children show an implicit pro-white bias when exposed to images of both white and black children. But the type of bias depended on what children were asked to do. The goal of the research was to gain a better understanding of children's automatic racial attitudes.

Researchers found that mothers of teenagers with autism spectrum disorder (ASD) or intellectual disability (ID) reported higher levels of stress and other negative psychological symptoms -- think depression or anxiety -- than mothers of teenagers with typical development (TD). Those levels climbed even higher when teenagers with ASD or ID also showed signs of clinical-level disruptive behavior disorders.

Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people's brains also wired differently to those of less intelligent persons? A new study supports this assumption. In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.

By six to nine months, babies already have a basic understanding of words for food and body parts. Researchers show that babies also recognize that words like 'car' and 'stroller' are more alike than 'car' and 'juice.' By analyzing home recordings, the team found that overall, babies' word knowledge correlated with the proportion of time they heard people talking about objects in their immediate surroundings.

Centuries of study have yielded many theories about how the brain gives rise to human intelligence. Some think it arises from a single region or neural network. Others argue that metabolism is key. A new article makes the case that the brain's dynamic properties -- how it is wired but also how that wiring shifts in response to changing intellectual demands -- are the best predictors of intelligence in the human brain.

Children who have been spanked by their parents by age 5 show an increase in behavior problems at age 6 and age 8 relative to children who have never been spanked, according to new findings. The study, which uses a statistical technique to approximate random assignment, indicates that this increase in behavior problems cannot be attributed to various characteristics of the child, the parents, or the home environment - rather, it seems to be the specific result of spanking.

When it comes to naming colors, most people do so with ease. But, for odors, it's much harder to find the words. One notable exception to this rule is found among the Jahai people, hunter-gatherers living in the Malay Peninsula. For them, odors are just as easy to name as colors. Now a new study suggests that the Jahai's special way with smell is related to their hunting and gathering lifestyle.

A musician's brain is different to that of a non-musician. Making music requires an interplay of abilities which are also reflected in more developed brain structures. Scientists have discovered that these capabilities are embedded in a much more finely tuned way than assumed: The brain activity of jazz pianists differs from those of classical pianists, even when playing the same piece of music.

When you catch a nasty cold, curling up in bed to sleep may be the only activity you can manage. Sleeping in response to stress isn't a uniquely human behavior: many other animals have the same reaction, and it's not clear why. While the circadian sleep that follows the pattern of the clock has been studied extensively, sleep that's triggered by stress is far less understood.

Recalling the names of old classmates 50 years after graduation or of favorite childhood television series illustrates the amazing abilities of human memory. Emotion and repeated exposure are both known to play a role in long-term memorization, but why do we remember things that are not emotionally charged and have only been seen or experienced a few times in the past? To answer this question, scientists decided to challenge the memory of individuals they had tested in the laboratory a decade previously. They discovered that participants recognized images seen for only a few seconds ten years earlier.

New research shows that challenging situations make it harder to understand where you are and what's happening around you. Researchers showed participants three clips from feature films -- one neutral, two challenging.

After humans and Neanderthals met many thousands of years ago, the two species began interbreeding. Recent studies have shown that some of those Neanderthal genes have contributed to human immunity and modern diseases.

Investigators took the pulse of fans during a hockey game and found that on average, their heart rate increased by 75 percent when watching on TV, and by a whopping 110 percent (more than doubled, equivalent to the cardiac stress with vigorous exercise) when watching in person.

Music touches. Until recently, this was only meant in a figurative way -- now it can also be taken literally. Scientists have now found that touch is perceived differently, depending on the music being played.

A new study provides the first in-depth analysis of the mouth clicks used in human echolocation.
