How Smartphones Could Revolutionize Scientific Experiments

Nick Clayton:

Cognitive psychology is, broadly, the study of mental processes almost as if the human mind was a type of computer. It is generally a highly empirical academic discipline relying on experimentation to study faculties such as language, attention and memory. It could be revolutionized by smartphones.

The current problem, according to a paper in peer-reviewed publication PLoS One, is that experiments usually rely on groups of volunteers coming to a research facility. By using smartphone technology instead, data could be collected from thousands of subjects across the world.

The paper comes from an international group of researchers who have been running a classic experiment which asks users to distinguish rapidly between words and non-words. (Its results can be used, for example, in the diagnosis of reading impairments.) Participants in the experiment downloaded a free app from iTunes to use on their iPhone or iPad.
