Older adults who take up drawing could enhance their memory, according to a new study from the University of Waterloo. Researchers found that even if people weren’t good at it, drawing, as a method to help retain new information, was better than rewriting notes, visualization exercises, or passively looking at images.
As part of a series of studies, the researchers asked both young people and older adults to do a variety of memory-encoding techniques and then tested their recall. The researchers believe that drawing led to better memory when compared with other study techniques because it incorporated multiple ways of representing the information—visual, spatial, verbal, semantic, and motoric. The researchers compared different types of memory techniques in aiding retention of a set of words in a group of undergraduate students and a group of senior citizens. Participants would either encode each word by writing it out, by drawing it, or by listing physical attributes related to each item. After performing each task, memory was assessed. Both groups showed better retention when they used drawing rather than writing to encode the new information, and this effect was especially large in older adults.
Retention of new information typically declines as people age due to deterioration of critical brain structures involved in memory such as the hippocampus and frontal lobes. In contrast, visuospatial processing regions of the brain, involved in representing images and pictures, are mostly intact in normal aging and in dementia.
Melissa Meade, PhD candidate in cognitive neuroscience at Waterloo, conducted this study with Myra Fernandes, a psychology professor in cognitive neuroscience at Waterloo, and recent UW PhD graduate Jeffrey Wammes. The study, “Drawing as an encoding tool: Memorial benefits in younger and older adults,” appears in Experimental Aging and Research.

of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally
accepted citation style for scientific papers:

About the ICMJE and citation styles
The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.
An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.
BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:
- Only the first three authors are listed, followed by "et al."
- There is no period after the journal name.
- Page numbers are not abbreviated.
