Practicing in the mind can also make you perfect | Thinking about something over and over again could actually be as good as doing it, says new study on perpetual learning. Elisa Tartaglia of the Laboratory of Psychophysics at Switzerland's Ecole Polytechnique
Federale de Lausanne (EPFL) said that perceptual learning-learning by repeated
exposure to a stimulus-could occur by mental imagery as much as by the real thing.
"When trained, radiologists are able to detect anomalies on medical images which
are extremely hard to detect for untrained people. The results of our study would
predict that mental imagery training, hence, repeatedly mentally visualizing the
anomalies that one wants to detect, would be sufficient to become able to detect
them," said Tartaglia. The researchers carried out a series of experiments, and
asked some participants to practice identifying which line, the right or the left
in a series of parallel lines, a central line was closest to and to identify it
by pushing the correct button. In follow-up, "post-training" exercises, these
participants improved their baseline performance significantly. And the same happened
when another set of volunteers who, instead of practicing with all three lines
in training, were instead asked to imagine the bisecting line's proximity based
on an audio tone. This group also improved their performance significantly in
further testing, meaning that "imagery training" was sufficient for perceptual
learning. Some experts question the relevance of mental imagery in this kind of
learning, which is generally assumed to be driven by stimulus processing-synapses
firing in response to a physical cue. Here, the researchers show that perceptual
learning can also occur by mental imagery, i.e., in the absence of physical stimulation.
The results help shine a light on what has been an ongoing puzzle in the field
and suggest an overlap in how-and possibly where-mental imagery affects perceptual
learning. The study has been published in Current Biology. |
