Being aware of our surroundings is a fundamental aspect of our existence. But what in our biological makeup determines how we access and interpret the endless stream of information around us? A new Tel Aviv University study published in Current Biology suggests that noradrenaline, a neurotransmitter responsible for arousal in the brain, plays a vital

Our eye hosts a powerful biological computer, the retina. Understanding how the retina transforms images from the outside world into signals that the brain can interpret would not only result in insights into brain computations, but could also be useful for medicine. As machine learning and artificial intelligence develop, eye diseases will soon be described

A fulsome smile in a photo makes it easier for people to identify the individual, say researchers at the University of York. Previous research at York has shown that it is difficult for people to match a pair of unfamiliar faces in photographs, presenting significant issues for authorities to spot identity fraud. Research has also

New research suggests that if people perceive the rise of vegetarianism as a threat to their way of life they are more likely to care less for some animals. Researchers from the University of Kent in the UK and Brock University in Canada studied the impact of human supremacy beliefs and vegetarianism on whether people

Dogs are capable of understanding the emotions behind an expression on a human face. For example, if a dog turns its head to the left, it could be picking up that someone is angry, fearful or happy. If there is a look of surprise on a person’s face, dogs tend to turn their head to

(HealthDay)—Dorsal reduction has a greater effect than tip manipulation in adding value to social perception of the facial profile of patients undergoing cosmetic rhinoplasty, according to a study published online June 7 in JAMA Facial Plastic Surgery. Cherian K. Kandathil, M.D., from Stanford University in California, and colleagues assessed the social perception of four patients

What makes someone go from simply being hungry to full-on “hangry”? More than just a simple drop in blood sugar, this combination of hunger and anger may be a complicated emotional response involving an interplay of biology, personality and environmental cues, according to research published by the American Psychological Association. “We all know that hunger

Struggling to finish that report for your boss? One way to increase your interest in a task is to add immediate rewards, rather than wait until the end to reward yourself, according to new Cornell research published in the Journal of Personality and Social Psychology titled “It’s About Time: Earlier Rewards Increase Intrinsic Motivation.” Kaitlin

‘Inattentional smell blindness’, or inattentional anosmia, has been proven to exist in a study from the University of Sussex. Just as it has previously been found that people can miss visual cues when they are busily engaged in a task, the same is true of smells. And unlike visual stimuli, which would be noticed once

It can be distressing to witness the pain of family, friends or even strangers going through a hard time. But what if, just like strengthening a muscle or learning a new hobby, we could train ourselves to be more compassionate and calm in the face of others’ suffering? That is the question behind research from

When was the last time you watched a Michael Jackson music video? If your answer is “never” or “not for quite a while,” you are really missing a treat. According to Rolling Stone, “No single artist … shaped, innovated or defined the medium of ‘music video’ more than Michael Jackson.” Back in the 1980s and

Bochum-based philosopher Dr Beate Krickel has used psychoanalysis to investigate why people are often not aware of their prejudices. In her accounts, she has been elaborating how prejudices can become unconscious. As researcher at the Institute of Philosophy II at Ruhr-Universität Bochum, she outlines her theory in the journal Philosophical Psychology from May 15, 2018.

Top-ranked reviewers on online retail sites such as Amazon.com may influence purchases, but a research study from Indiana University’s Kelley School of Business finds that those who post reviews less often and more informally can be seen as more trustworthy and have more of an impact on sales. Shyam Gopinath, assistant professor of marketing at

We rely on our ears to tell us where sounds — from the chirp of a bird to the call of your name in a crowd — are coming from. Locating and discriminating sound sources is extremely complex because the brain has to process spatial information from many, sometimes conflicting, cues. Using virtual reality and

Sorry, new moms and dads — even though your infants really do appreciate your squeaky coos, they would prefer to hear sounds from their peers — other babies. Even at the pre-babbling stage — before they can form sounds resembling syllables like “ba ba ba” — infants recognize vowel-like sounds, but they tend to dwell

Scientists have shone new light on how the human brain uses past experiences and generalizes them to future events, helping us safely navigate the world around us, a study in eLife reveals. Our ability to ‘generalize’ is an important survival technique, but over-generalizing from bad events could explain why some people fear and then avoid

We rely on our ears to tell us where sounds—from the chirp of a bird to the call of your name in a crowd—are coming from. Locating and discriminating sound sources is extremely complex because the brain has to process spatial information from many, sometimes conflicting, cues. Using virtual reality and other immersive technologies, researchers

Blurry and clear versions of an image are represented similarly in the brain, according to a neuroimaging study published in eNeuro. The research shows how the visual system fills in missing information to maintain perception when visibility is low. Vision arises from a “bottom-up” process that transduces light into neural signals and a “top-down” process

Neuroscience has studied music for decades, and it has been found to activate both the cortical and deeper brain areas. Neuroscience of dance, instead, is a young but quickly growing field. In her doctoral dissertation, Master of Science Hanna Poikonen developed methods for understanding the processes that dance generates in the cortex at the Cognitive

People rely on financial managers, doctors and lawyers to be as objective as possible when making decisions about investments, health and legal issues, but findings from a new study suggest that an unexpected factor could be influencing these choices. In a series of experiments, researchers found that people at higher elevations in an office building
