A new study at from the Center for Healthy Minds suggests that people can train their minds to stay focused.
The study, led by UW–Madison scientist Antoine Lutz, involved subjects interested in meditation in an effort to see whether voluntary mental training can affect attention. Results suggest that attention stability is not a fixed capacity, and that it can be improved by directed mental training, such as meditation.
“Everyone is familiar with daydreaming,” says Lutz, who works jointly with the Waisman Brain Imaging Lab and the new Center. “These momentary lapses into mind-wandering occur even when a person is trying to stay focused on a chosen object. The difficulty of focused attention is evident both in everyday experiences and in the laboratory.”
Being able to sustain attention on a chosen object through time is a critical component of attention regulation, explains the study’s senior scientist Richard Davidson, director of the Center and professor of psychology and psychiatry at UW–Madison.
“In untrained individuals, one gets easily distracted, requiring a refocusing of attention,” says Davidson. “Such ongoing fluctuations in attention stability are thought to reflect competitive interactions between task-related and task-unrelated processes, such as mind-wandering. Our work holds that the capacity to stabilize attention is best regarded as a skill that can be trained.”
Participants were presented with frequent standard and rare deviant tones in both ears, and asked to pay attention only to tones presented in one ear and to press a button each time they detected an intermittent deviant tone. Deviant tones were slightly higher in frequency than standard tones. Lutz and colleagues investigated the moment-to-moment stability of attention by quantifying the trial-to-trial variability of both reaction time in response to attended deviant tones and consistency of brain responses, as measured by electroencephalography (EEG).
