Four studies involving a total of more than 300 younger adults (20-24) have looked at information processing on different forms of media. They found that digital platforms such as tablets and laptops for reading may make you more inclined to focus on concrete details rather than interpreting information more abstractly.
As much as possible, the material was presented on the different media in identical format.
A study into how well students understand specific diagrams reminds us that, while pictures may be worth 1000 words, even small details can make a significant difference to how informative they are.
The study focused on variously formatted cladograms (also known as phylogenetic trees) that are commonly used in high school and college biology textbooks. Such diagrams are hierarchically branching, and are typically used to show the evolutionary history of taxa.
I always like studies about embodied cognition — that is, about how what we do physically affects how we think. Here are a couple of new ones.
A pilot study involving 10 patients with moderate Alzheimer's disease, of whom half were randomly assigned to the treatment, has found that two weeks of receiving daily (25 minute) periods of repetitive transcranial magnetic stimulation to the prefrontal lobes produced a significant improvement in the patients’ ability to understand spoken language. Correct answers on a comprehension test rose from 66% to over 77%. Two further weeks of the treatment produced no further improvement, but the improvements were still evident eight weeks after the end of the treatment.
