The Science of Happiness Sounds Great. But Is the Research Solid?
In a new review in the journal Nature Human Behavior, researchers Elizabeth Dunn and Dunigan Folk found that many common strategies for increasing our happiness may not be supported by strong evidence. In fact, almost 95% of experiments on three common strategies—spending time in nature, exercise and engaging in mindfulness/meditation—did not hold up to even the most basic of current best practices for showing psychological effects. ...

Silence Is a ‘Sound’ You Hear, Study Suggests
The hush at the end of the musical performance. The pause in a dramatic speech. The muted moment when you turn off the car. What is it that we hear when we hear nothing at all? Are we detecting silence? Or are we just hearing nothing and interpreting that absence as silence? The “Sound of Silence” is a philosophical question that made for one of Simon & Garfunkel’s most enduring songs, but it’s also a subject that can be tested by psychologists. In a paper published Monday in the Proceedings of the National Academy of Sciences, researchers used a series of sonic illusions to show that people perceive silences much as they hear sounds.

To Stay Sharp as You Age, Learn New Skills
In most adults, learning and thinking plateau and then begin to decline after age 30 or 40. People start to perform worse in tests of cognitive abilities such as processing speed, the rate at which someone does a mental task. The slide becomes steeper after 60 years of age. These changes are often ascribed to normal aging. But what if instead they represent something more like the “summer slide” that schoolchildren experience? Every year teachers and parents observe how summer vacations lead some children’s academic progress to backslide.

Trouble Achieving Goals? Why Your Brain Needs Reminders.
Many of us set goals, but sometimes we fail to achieve them. There is a way, though, to increase our chances of hitting our goals: Set reminders. “It’s quite hard to achieve our goals,” said Sam Gilbert, professor of cognitive neuroscience at the University College London. “There are many, many reasons why we get led astray, or we don’t manage to realize our goals.” One common, but addressable reason is that we simply forget them. Psychological studies suggest that 50 to 70 percent of our everyday memory failures involve forgetting our intentions. Creating reminders can help address this problem. Research explains why.
