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.
Major beer companies have rolled out marketing campaigns and products -- such as 'fan cans,' store displays, and billboard ads -- that pair beer with university colors, mascots, and logos. Research shows that such campaigns may enhance the motivational significance of marketed beer brands, especially for students who identify strongly with their university. The researchers conclude that this effect could potentially increase underage students' alcohol consumption.
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.
For patients who have never been prescribed opioids, larger numbers of tablets given with the initial prescription is associated with long-term use and more tablets leftover that could be diverted for misuse or abuse. Implementing a default option for a lower quantity of tablets in the electronic medical records (EMR) discharge orders may help combat the issue by “nudging” physicians to prescribe smaller quantities consistent with prescribing guidelines.
Ethicists have outlined a new biosecurity framework specific to neurotechnology. While the researchers declare an outright ban of dual-use technology ethically unjustified, they call for regulations aimed at protecting the mental privacy and integrity of humans.
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.
While some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet's animals and plants experiencing the most stress.
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.
Frequently encountered in the elderly, Alzheimer's is considered a neurodegenerative disease, which means that it is accompanied by a significant, progressive loss of neurons and their nerve endings, or synapses. A new study now challenges this view.
A new study of nursing homes in California, the nation's largest system found that some nursing homes inflate their self-assessment reporting to improve their score in the Five-Star Quality Rating System employed by Medicare to help consumers.
Recording brain activity via electrodes placed directly on the cortical surface (ECoG) provides much clearer views of thinking activity and how the prefrontal cortex coordinates the brain's response to a perception. With the help of 16 epilepsy patients, neuroscientists tracked the brain's activity as it detects, interprets, settles on a response and activates motor areas to respond. The brain prepares to respond very early, even before we know how we will respond.
