As the older population grows in numbers, there is an increasing social urgency to find ways to maintain or even improve one’s cognitive health.  As we age, declines in memory, attentional control, speed of processing, and problem-solving abilities are expected and are considered to be typical of normal, healthy aging. Past studies have shown the links between participation in cognitive, leisure and social activities with improved cognitive ability, as well as a decreased risk of Alzheimer’s Disease.  However little evidence has been found on whether sustained lifestyle engagement can help to maintain or improve cognitive function.  This study by Park et al. (2013) sought to examine the impact of sustained engagement on the cognitive abilities of older adults. This study is called the “Synapse Project” because unlike normal cognitive training, in which participants come in for an experiment that typically last a few hours or a few days, the participants in this study agree to make a lifestyle change in that they are learning new, demanding real-world skills in a social environment.

Surprisingly, recent data have shown that approximately a third of witnesses for line-ups are children younger than 16 years old. The data also show that about a third of these children under 16 are likely to make a false identification of an innocent person as the culprit. It goes without saying that there can be very serious and severe outcomes for people as a result of false identification. For these reasons, research on eyewitness testimony has become more important and prominent in recent times.  Read more…
