Danilo Díaz Granados read: The act of drawing something has a “massive” benefit for memory compared with writing it down

giphyBy Emma Young

A picture is worth a thousand words…. When it comes to conveying a concept, this sentiment can certainly be true. But it may also be the case for memory. At least that’s the message from Myra Fernandes and colleagues at the University of Waterloo, Canada – writing in Current Directions in Psychological Science, they argue that their research programme shows that drawing has a “surprisingly powerful influence” on memory, and as a mnemonic technique, it could be particularly useful for older adults – and even people with dementia.

Fernandes and her colleagues first established what they call the “drawing effect” – getting people to draw quick pictures of words in a list (such as “truck” or “pear”) led to much better recall of those words than writing them out multiple times. Creating just a four-second drawing was also superior to imagining the items or viewing pictures of the words. 

This was proof of principle type work. The researchers next looked at whether drawing aids memory of more complex terms and concepts. They found that study participants who had a minute to draw an image representing “isotope” or “spore”, for example, were more likely to remember the meaning than people who were asked to copy out the definitions instead. “As with single words, we reasoned that drawing facilitates retention, at least in part, because it requires elaboration on the meaning of the term and translating the definition to a new form (a picture),” the researchers write. 

In fact, there are various components to the process of drawing a picture of a word or concept, each of which seem to cumulatively aid memory. Getting people to trace over an existing drawing (so getting them to make relevant arm and hand movements, but not allowing personal elaboration), or to create a drawing which they were then not allowed to see (so allowing the physical movements and personal elaboration, but depriving them of the visual memory of the end result) both improved memory – but not as much as when all of these stages were allowed. “Memory scaled up as components were added to the encoding task,” the researchers note. 

Fernandes and her colleagues went on to find that although older adults performed worse than younger adults at remembering words they had learned by writing, there was no difference between the two age groups in their ability to remember words they had drawn. Encouraged by these results, the team then asked 13 people diagnosed with dementia and living in a long-term care facility to either draw or write 60 words that were read aloud by an experimenter. The results showed a “massive” memory benefit for words that had been drawn rather than written. If it can be shown that drawing also helps with other sorts of memory – for where things are kept, perhaps – this strategy could be practically useful for people with dementia.

In some cases, the patients’ drawings looked just like scribbles. But how good – or bad – the drawings were didn’t seem to matter. In fact, in most of the experiments, the researchers assessed their participants’ ability to create vivid images and also their experience at drawing, and neither was correlated with memory performance. Even people who struggle to create a stick figure should, then, get memory benefits from drawing. 

There’s still plenty of work to be done to investigate whether drawing terms, events or concepts that you want to recall can bring real-world benefits – whether in the classroom or in a care home. But this is a comprehensive set of studies, all pointing in the same direction. “Taken together, the evidence…demonstrates that drawing is a robust encoding strategy that can, and does, improve memory performance dramatically,” the researchers conclude.

Danilo Díaz Granados read: “Skunk” Cannabis Disrupts Brain Networks – But Effects Are Blocked In Other Strains

By Matthew Warren Over the past decade, neuroimaging studies have provided new insights into how psychoactive drugs alter the brain’s activity. Psilocybin – the active ingredient in magic mushrooms – has been found to reduce activity in brain regions involved in depression , for example, while MDMA seems to augment brain activity for positive memories . Now a new study sheds some light into what’s going in the brain when people smoke cannabis – and it turns out that the effects can be quite different depending on the specific strain of the drug. The research, published recently in the Journal of Psychopharmacology , suggests that cannabis disrupts particular brain networks  – but some strains can buffer against this disruption. Cannabis contains two major active ingredients: tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is responsible for many of the drug’s psychoactive effects, such as the feeling of being stoned and the anxiety that people sometimes feel, as well as ...

Danilo Díaz Granados read: Beyond the invisible gorilla – inattention can also render us numb and anosmic (without smell)

By Emma Young It’s well-known that we can miss apparently obvious objects in our visual field if other events are hogging our limited attention. The same has been shown for sounds: in a nod to Daniel Simons’ and Christopher Chabris’ famous gorilla/basketball study that demonstrated “inattentional blindness”, distracted participants in the first “inattentional deafness” study failed to hear a man walking through an auditory scene for 19 seconds saying repeatedly “I am a gorilla”. Now, two new studies separately show that a very similar effect occurs in relation to touch ( inattentional numbness ) and to smell   ( inattentional anosmia ).   Sandra Murphy and Polly Dalton (a co-author on the inattentional deafness paper) at Royal Holloway, University of London report in the journal Cognition on inattentional numbness. They wanted to go beyond the way we rapidly tune out ongoing tactile stimulation, like the sensation of our clothes, and explore what happens when we’re tou...

Danilo Díaz Granados read: A New Study Has Investigated Who Watched The ISIS Beheading Videos, Why, And What Effect It Had On Them

By Emma Young In the summer of 2014, two videos were released that shocked the world. They showed the beheadings, by ISIS, of two American journalists – first, James Foley and then Steven Sotloff. Though the videos were widely discussed on TV, print and online news, most outlets did not show the full footage. However, it was not difficult to find links to the videos online. At the time, Sarah Redmond at the University of California, Irvine and her colleagues were already a year into a longitudinal study to assess psychological responses to the Boston Marathon Bombing, which happened in April 2013. They realised that they could use the same nationally representative sample of US adults to investigate what kind of person chooses to watch an ISIS beheading – and why. Their findings now appear in a paper published in American Psychologist .   By late spring 2013, the researchers had recruited 4,675 adults online, and assessed their mental health, TV-watching habits, demographics,...
