Can hearing dogs provide measurable benefit for individuals with severe or profound hearing loss?
Stuttard and colleagues (2021) examined the effects on mental well-being, anxiety, depression, functional impairments, and hearing-related difficulties for adults with either severe or profound hearing loss after having had a hearing support dog for six months. They also evaluated the cost-effectiveness of the program related to quality-adjusted life years.
Study participants were randomized to either receive a hearing dog or to a waitlist group. Statistical analyses generally found significant differences between study groups across the majority of test measures with better outcomes being reported by those who received a hearing dog. Effect sizes were reported to be small to medium.
Study results also suggested that the hearing dog program was cost effective when the expenses were covered the charity doing the study (Hearing Dogs for Deaf People), but not when the cost of providing the hearing dog was covered by the public health-care system (National Health Service).

“Huh?” is used in at least 31 languages around the world! A version of the word can be found in nearly every language on Earth (Dingemanse et al, 2013). This research concluded that all languages studied included a word similar, in both sound and function, to the English “huh?” Regardless of language, the word is…
If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
