Older Adults Are Better at Listening Than You Think



Contrary to popular belief, older persons may have improved hearing in noisy social settings.

Ever sneer when your grandmother asks you to help clear the table after a meal with the family or gripe when your grandfather cheats during a competitive game of gin rummy? Given the likelihood that people can hear you more clearly than you realize, you might wish to talk less loudly.

According to recent studies from Baycrest and Western University, older people may have better hearing in noisy environments than previously believed. Whether it's at a packed restaurant or a crowded family gathering, older folks may enjoy and process conversations better than earlier research have suggested. If this were to be true, it would improve their quality of life and give them the chance to meaningfully interact with people who are going through similar things, which would reduce their risk of developing dementia as social isolation is a risk factor for cognitive decline.

Scientists have long hypothesized that older persons appear to be less able to use speech "glimpses" than younger adults, which involve exploiting the speech one can hear more clearly during brief reductions in background noise to better understand conversations in noisy surroundings.

The Baycrest-Western University study suggests, however, that this may not hold true for speech that is more like human speech and may only hold true for the fairly uninteresting, jumbled, and unnatural sentences that are frequently used in laboratory settings. In other words, it might be simpler than previously thought for older persons to hear speech in noisy settings.

Younger and older adult participants in the study, which was published in the journal Scientific Reports, listened to captivating stories or disjointed words without a clear topic, such as "Smoky fires lack flame and heat." Two different types of background noise were provided by the researchers: one that fluctuated in level to allow for glances and one that did not. The speech and background noise were frequently interrupted by the researchers, who then asked the subjects to describe in detail what they had heard. The number of words that were correctly interpreted was then calculated by the researchers.

They discovered that older persons profited from speech glimpses as much as, if not more than, younger adults did for more natural speech that resembles speaking in everyday life, such as storytelling. When listening to fragmented sentences, however, they profited less.

These findings imply that older persons can be more adept at hearing in noisy social environments than previously believed. The significance of cognitive and motivational elements for speech understanding is further highlighted by our study. Senior author of this study and Baycrest's Canada Research Chair in Auditory Aging, Dr. Björn Herrmann notes that older persons who struggle with listening skills in a lab context may perform better in real-world situations.

With greater funding, Dr. Herrmann and his team could research why natural speech, as opposed to isolated laboratory sentences, benefits older persons' hearing more, as well as how natural speech might be utilized more frequently in clinical practice to test older adults' hearing.

Do You Sleep on Your Back or Side? Here's The Research on 'Optimal' Sleep Positions

Image
William Dement, a renowned sleep researcher at Stanford University, is quoted as saying that after 50 years of study, the only reason he can think of for why we sleep is "because we become sleepy." Sleep certainly matters for our health and wellbeing even though it may be, as one researcher put it, "the sole major habit in quest of a function." Do we, however, have it right? What do studies on sleeping positions say? Is there a proper sleeping position? The majority of people favor sleeping on their side. This is encouraging news because people who sleep on their backs are more likely to have trouble falling asleep or breathing during the night. Most of the time, we have a tendency to shift around quite a bit at night. According to a study involving 664 sleepers, on average, participants slept on their side 54% of the time, their back 37% of the time, and their front 7% of the time. Males are more likely to change positions throughout the night and move their arms, ...

North America’s Rarest Snake Found Dead

Image
The Tantilla oolitica (rim rock crowned snake), the rarest snake in North America, was recently rediscovered in a Florida Keys park after a four-year hiatus. Even though a snake encounter would normally be cause for celebration among conservationists, it was more of a source of astounding wonder than anything else. The snake was found to be dead, fighting a large centipede that it had partially swallowed in a lifeless battle. Experts haven't previously observed the snake's feeding patterns due to the tragic confrontation. T. oolitica is so uncommon that no one knew what it consumed until now, despite the fact that it is well known that closely related species enjoy centipedes. Researchers from the Florida Museum of Natural History CT scanned the entangled pair and just published their results in the journal Ecology. Coleman Sheehy, co-author and manager of the herpetology collection at the Florida Museum, remarked, "I was surprised when I first viewed the images. "Sam...

Breakthrough: Physicists Take Particle Self-Assembly to New Level by Mimicking Biology

Image
A group of physicists have developed a brand-new technique for self-assembling particles. This development offers fresh hope for creating intricate and cutting-edge materials at the tiny scale. Self-assembly, which was developed in the early 2000s, provides scientists with a way to "pre-program" particles, enabling the creation of materials without additional human involvement. This is essentially the smallest version of self-assembling Ikea furniture. The discovery, which was published today, September 28, in the journal Nature, focuses on emulsions—oil droplets dissolved in water—and how they might be used to help foldamers self-assemble. The sequence of droplet interactions can possibly be used to anticipate these particular shapes. Through interactions between blue-blue, blue-yellow, and eventually yellow-yellow droplets, which are all mediated by sticky DNA strands, a chain of alternating blue and yellow droplets folds into a crown shape in microscopy images. The image a...
