University students who identify as strong in mathematics quickly forgot much of the material from a mathematics course. The explanation: We tend to forget unpleasant experiences and memories that threaten our self-image as a way to preserve our psychological well-being.
Why do some men crack sexist and anti-gay jokes or find them funny, while others do not? According to a new study, such disparaging jokes are a way for some men to reaffirm their shaky sense of self, especially when they feel their masculinity is being threatened. Interestingly, in such situations men do not revert to neutral jokes or ones containing anti-Muslim sentiments, comments the author.
Despite spending at least one quarter to one third a day sleeping, good sleep can elude many people, and the diagnosis and treatment of sleep disorders remains primitive. Researchers have designed new technology that uses machine learning to model a personal sleep pattern based on the sounds made during sleep. Because the sounds can be recorded at home with no fancy devices, it is expected that doctors using this technology could diagnose patients under normal sleeping conditions, which is expected to lead to better treatment.
Every year, falls lead to hospitalization or death for hundreds of thousands of elderly Americans. Standard clinical techniques generally cannot diagnose balance impairments before they lead to falls. But researchers have found evidence that virtual reality (VR) could be a big help - not only for detecting balance impairments early, but perhaps also for reversing those impairments and preventing falls.
Friendships play a vital role in helping people get through substantial challenges in life, according to a new study. Until now, little research has been carried out into the role friends and, in particular, best friends play in building resilience to adversity - surviving and thriving in the face of difficult times. The new preliminary study provides long-term statistical evidence of the enormous benefit these valued social relationships have on adults' resilience.
Researchers have developed a sensor-filled glove that doctors could wear to accurately measure muscle stiffness, known as spasticity, in patients suffering from stroke, cerebral palsy, multiple sclerosis and other muscle control disorders.
An estimated 1.6 to 3.8 million traumatic brain injuries occur every year. More than 75 percent of the injuries are sports-related mild traumatic brain injuries or concussions. Now a study focuses on concussion specialists using telemedicine technology to determine if a player needs to be removed from play in real time.
Electrical stimulation delivered when memory is predicted to fail can improve memory function in the human brain, a team of neuroscientists shows for the first time. That same stimulation generally becomes disruptive when electrical pulses arrive during periods of effective memory function.
The relationship between head injuries suffered during contact sport and Alzheimer’s disease is now being called into question thanks to new research that has revealed that hockey players with multiple concussions probably have other injuries in their brains.
Working with oral histories in schools has become very popular in Germany, the United States and many other countries. Eyewitnesses of the past are able to deliver authentic accounts of events in their lives which affect students more deeply than written texts. Furthermore, teachers hope that working with eyewitnesses encourages students to work like historians and, for example, to critically question their sources. But there is also criticism of this method. On the one hand, memory is a reconstructive process which can be influenced by many factors. On the other hand, the aura and authenticity of the eyewitnesses can result in an uncritical acceptance of their accounts.
Context can alter something as basic as our ability to estimate the weights of simple objects. As we learn to manipulate those objects, context can even tease out the interplay of two memory systems and shows how distraction can affect multitasking.
A new nationally representative survey of American teenagers age 13-17 finds that teens have shifted their favored social media platforms and are now most likely to use Instagram and Snapchat. The study also found that while almost all teens -- 91 percent -- use the regular text messaging tool on their mobile phones, 40 percent of teens also use messaging applications like Kik, WhatsApp, or Line on a smartphone.
Family structure including regular bedtimes, mealtimes and limited screen time appear to be linked to better emotional health in preschoolers, and that might lower the chances of obesity later, a new study suggests.
