In a series of experiments involving college students, drawing pictures was found to be the best strategy for remembering lists of words.

A study involving 60 undergraduate students confirms the value of even a single instance of retrieval practice in an everyday setting, and also confirms the value of cues for peripheral details, which are forgotten more readily.

A Canadian study involving French-speaking university students has found that repeating aloud, especially to another person, improves memory for words.

In the first experiment, 20 students read a series of words while wearing headphones that emitted white noise, in order to mask their own voices and eliminate auditory feedback. Four actions were compared:

We know that the neurotransmitter

Sleep, as I have said on many occasions, helps your brain consolidate new memories. I have reported before on a number of studies showing how sleep helps the learning of various types of new information. Most of those studies have looked at procedural learning (learning new skills), or verbal learning. A new study adds to these by looking at face-name associations.

Mindfulness meditation is associated with various positive benefits, one of which is improved attention, but it might not be all good. A new study suggests that it may have negative cognitive consequences.

The study included three experiments, in the first two of which undergraduates carried out a 15-minute guided exercise: one group was instructed to focus attention on their breathing without judgment (mindfulness group); the other group was told to think about whatever came to mind (mind-wandering group; the control).

A small study using an artificial language adds to evidence that new vocabulary is learned more easily when the learner uses gestures.

“Vimmish”, the artificial language used in the study, follows similar phonetic rules to Italian. The German-speaking participants were given abstract and concrete nouns to learn over the course of a week. In the first experiment, the 21 subjects heard the words and their translations under one of three conditions:

I've written at length about implementation plans in my book “Planning to Remember: How to Remember What You're Doing and What You Plan to Do”. Essentially, they're intentions you make in which you explicitly tie together your intended action with a specific situational cue (such as seeing a post box).

This is just a preliminary study presented at a recent conference, so we can't give it too much weight, but the finding is consistent with what we know about

A review of meditation research reported in January last year concluded that there were insufficient good studies to allow us to say that meditation clearly improves attention and cognition. Studies from 2014 suggest three factors that might be part of the reason for inconsistent research findings:

In 2013 I reported how a 3-second interruption while doing a task doubled the rate of sequence errors, while a 4s one tripled it. A new study has attempted to measure just how much ongoing interruptions can negatively affect the quality of a complex creative task.

I’ve reported often on the perils of multitasking. Here is yet another one, with an intriguing new finding: it seems that the people who multitask the most are those least capable of doing so!

The study surveyed 310 undergraduate psychology students to find their actual multitasking ability, perceived multitasking ability, cell phone use while driving, use of a wide array of electronic media, and personality traits such as impulsivity and sensation-seeking.

Online social networking, such as Facebook, is hugely popular. A series of experiments has explored the intriguing question of whether our memories are particularly ‘tuned’ to remember the sort of information shared on such sites.

I’ve discussed before how hard it is to correct false knowledge. This is not only a problem for the classroom — the preconceptions students bring to a topic, and the difficulty of replacing them with the correct information — but, in these days of so much misinformation in the media and on the web, an everyday problem.

Here’s an encouraging study for all those who think that, because of age or physical damage, they must resign themselves to whatever cognitive impairment or decline they have suffered. In this study, older adults who had suffered from aphasia for a long time nevertheless improved their language function after six weeks of intensive training.

I reported recently on how easily and quickly we can get derailed from a chain of thought (or action). In similar vein, here’s another study that shows how easy it is to omit important steps in an emergency, even when you’re an expert — which is why I’m a great fan of checklists.

Sometime ago, I reported on a study showing that older adults could improve their memory for a future task (remembering to regularly test their blood sugar) by picturing themselves going through the process. Imagination has been shown to be a useful strategy in improving memory (and also motor skills). A new study extends and confirms previous findings, by testing free recall and comparing self-imagination to more traditional strategies.

More evidence that even an 8-week meditation training program can have measurable effects on the brain comes from an imaging study. Moreover, the type of meditation makes a difference to how the brain changes.

In my last report, I discussed a finding that intensive foreign language learning ‘grew’ the size of certain brain regions. This growth reflects gray matter increase. Another recent study looks at a different aspect:

A small Swedish brain imaging study adds to the evidence for the cognitive benefits of learning a new language by investigating the brain changes in students undergoing a highly intensive language course.

Back in 2010, I briefly reported on a study suggesting that a few minutes of ‘quiet time’ could help you consolidate new information. A new study provides more support for this idea.

Here’s an exciting little study, implying as it does that one particular aspect of information processing underlies much of the cognitive decline in older adults, and that this can be improved through training. No, it’s not our usual suspect,

Spatial abilities have been shown to be important for achievement in STEM subjects (science, technology, engineering, math), but many people have felt that spatial skills are something you’re either born with or not.

I’ve reported, often, on the evidence that multitasking is a problem, something we’re not really designed to do well (with the exception of a few fortunate individuals), and that the problem is rooted in our extremely limited

My recent reports on brain training for older adults (see, e.g., Review of working memory training programs finds no broader benefit; Cognitive training shown to help healthy older adults; Video game training benefits cognition in some older adults) converge on the idea that cognitive training can indeed be beneficial for older adults

Adding to the growing evidence for the long-term cognitive benefits of childhood music training, a new study has found that even a few years of music training in childhood has long-lasting benefits for auditory discrimination.

I’ve reported before on how London taxi drivers increase the size of their posterior

Meditation may improve multitasking

I recently reported that developing skill at video action games doesn’t seem to improve general multitasking ability, but perhaps another approach might be more successful. Meditation has, of course, been garnering growing evidence that it can help improve attentional control. A new study extends that research to multitasking in a realistic work setting.

The research is pretty clear by this point: humans are not (with a few rare exceptions) designed to multitask. However, it has been suggested that the modern generation, with all the multitasking they do, may have been ‘re-wired’ to be more capable of this. A new study throws cold water on this idea.

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.

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.

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.

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.

I have said before that there is little evidence that

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.

I’ve talked before about Dr Berman’s research into Attention Restoration Theory, which proposes that people concentrate better after nature walks or even just looking at nature scenes. In his latest study, the findings have been extended to those with clinical depression.

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.

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.

Data from the very large and long-running Cognitive Function and Ageing Study, a U.K. study involving 13,004 older adults (65+), from which 329 brains are now available for analysis, has found that cognitive lifestyle score (CLS) had no effect on Alzheimer’s pathology. Characteristics typical of Alzheimer’s, such as plaques,

Previous research has been equivocal about whether cognitive training helps cognitively healthy older adults. One recent review concluded that cognitive training could help slow age-related decline in a range of cognitive tasks; another found no evidence that such training helps slow or prevent the development of Alzheimer’s in healthy older adults. Most of the studies reviewed looked at single-domain training only: memory, reasoning, processing speed, reading, solving arithmetic problems, or strategy training (1).
