Tai Chi improves cognition and brain size in older adults

The study involved 120 healthy older adults (60-79) from Shanghai, who were randomly assigned to one of four groups: one that participated in three sessions of tai chi every week for 40 weeks; another that instead had ‘social interaction’ sessions (‘lively discussions’); another in which participants engaged in walking around a track; and a non-intervention group included as a control. Brain scans were taken before and after the 40-week intervention, and cognitive testing took place at 20 weeks as well as these times.

Boost creativity by living abroad

A couple of years ago I briefly reported on a finding that students who had lived abroad demonstrated greater creativity, if they first recalled a multicultural learning experience from their life abroad. A new study examines this connection, in particular investigating the as-yet-unanswered question of whether students who studied abroad were already more creative than those who didn’t.

Sleep learning making a comeback?

Back when I was young, sleep learning was a popular idea. The idea was that a tape would play while you were asleep, and learning would seep into your brain effortlessly. It was particularly advocated for language learning. Subsequent research, unfortunately, rejected the idea, and gradually it has faded (although not completely). Now a new study may presage a come-back.

Immediate reward improves low-performing students’ test scores

In contradiction of some other recent research, a large new study has found that offering students rewards just before standardized testing can improve test performance dramatically. One important factor in this finding might be the immediate pay-off — students received their rewards right after the test. Another might be in the participants, who were attending low-performing schools.

Review of working memory training programs finds no broader benefit

I have said before that there is little evidence that working memory training has any wider benefits than to the skills being practiced. Occasionally a study arises that gets everyone all excited, but by and large training only benefits the skill being practiced — despite the fact that working memory underlies so many cognitive tasks, and limited working memory capacity is thought to negatively affect performance on so many tasks.

Extra-large letter spacing improves reading in dyslexia

It’s generally agreed among researchers that the most efficient intervention for dyslexia is to get the child reading more — the challenge is to find ways that enable that. Training programs typically target specific component skills, which are all well and good but leave the essential problem untouched: the children still need to read more. A new study shows that a very simple manipulation substantially improves reading in a large, unselected group of dyslexic children.

Blind people are 'serial memory' whizzes

In a demonstration of the benefits of mental training, a study tested the memory of 19 congenitally blind individuals and individually matched sighted controls. Those who were blind recalled more words than the sighted, but their greatest superiority was the ability to remember longer word sequences according to their original order. This is probably a result of blind people’s everyday reliance on serial-memory strategies to identify otherwise indistinguishable objects. The finding that the blind showed a better memory for all of the words regardless of where they fell (rather than the first and last word advantage more typically found) suggests that the key to their success may lie in representing item lists as word chains, perhaps by generating associations between adjacent items.

Brain Imaging Identifies Best Memorization Strategies

Why do some people remember things better than others? An imaging study has revealed that the brain regions activated when learning vary depending on the strategy adopted. The study involved 29 right-handed, healthy young adults, ages 18-31, all of whom had normal or corrected-to-normal vision and reported no significant neurological history. Participants were given interacting object pair images (such as a turkey seated atop a horse and a banana positioned in the back of a dump truck) and told to study them in anticipation of a memory test. Earlier studies had indicated that while individuals use a variety of strategies to help them memorize new information, the following four strategies were the main strategies:

1) A visual inspection strategy in which participants carefully studied the visual appearance of objects.

2) A verbal elaboration strategy in which individuals constructed sentences about the objects to remember them.

3) A mental imagery strategy in which participants formed interactive mental images of the objects.

4) A memory retrieval strategy in which they thought about the meaning of the objects and/or personal memories associated with the objects.

Both visual inspection and verbal elaboration resulted in improved recall. Imaging revealed that people who often used verbal elaboration had greater activity in a network of regions that included prefrontal regions associated with controlled verbal processing compared to people who used this strategy less frequently. People who often used a visual inspection strategy had greater activity in a network of regions that included an extrastriate region associated with object processing compared to people who used this strategy less frequently.

Sleeping after learning is most effective

We know that we remember more 12 hours after learning if we have slept during that 12 hours rather than been awake throughout, but is this because sleep is actively helping us remember, or because being awake makes it harder to remember (because of interference and over-writing from other experiences). A new study aimed to disentangle these effects.

In the study, 207 students were randomly assigned to study 40 related or unrelated word pairs at 9 a.m. or 9 p.m., returning for testing either 30 minutes, 12 hours or 24 hours later.

How action videogames change some people’s brains

Following on from research finding that people who regularly play action video games show visual attention related differences in brain activity compared to non-players, a new study has investigated whether such changes could be elicited in 25 volunteers who hadn’t played video games in at least four years. Sixteen of the participants played a first-person shooter game (Medal of Honor: Pacific Assault), while nine played a three-dimensional puzzle game (Ballance). They played the games for a total of 10 hours spread over one- to two-hour sessions.
