Abstract
Commentary: When the brain takes a break: a model-based analysis of mind wandering.
Highlights
In recent years, the importance of integrating cognitive modeling with neuroimaging experiments has been repeatedly emphasized (e.g., Forstmann et al, 2011; Brown, 2014)
The recent work of Mittner et al (2014), which explored the mechanisms of mind-wandering using a combination of brain imaging, pupillometry and cognitive modeling, serves as an important illustration of how this methodological amalgam can be effectively implemented
About 15% of the pseudorandom “go-trials” were followed by thought probes, requiring participants to rate their level of mind-wandering during the preceding trial
Summary
The importance of integrating cognitive modeling with neuroimaging experiments has been repeatedly emphasized (e.g., Forstmann et al, 2011; Brown, 2014). The recent work of Mittner et al (2014), which explored the mechanisms of mind-wandering using a combination of brain imaging, pupillometry and cognitive modeling, serves as an important illustration of how this methodological amalgam can be effectively implemented. The main benefit of using a combination of brain imaging, pupillometry, and behavioral measures over a typical behavioral experiment (e.g., Mcvay and Kane, 2012) was that it provided an estimation of mindwandering levels for hundreds of consecutive trials, without the added distraction of incessant thought probes.
