As we mature into old age, our ability to remain focused and quickly choose the correct response from a set of competing responses tends to diminish. Can mindfulness training help us retain our attention, executive control and emotional regulation as we age? Malinowski, et al [Mindfulness] randomly assigned mature adults to either mindfulness training or an active comparison group, and assessed the changes in their ability to perform a task that demanded focused attention, executive control, and emotional regulation while their brain activity was measured.
The researchers assigned a predominantly female cohort of 56 British older adults (average age = 64) to either mindfulness training or a “brain training” comparison condition. Mindfulness training entailed four 90-minute group-training sessions in breath-focused concentration meditation with instructions for maintaining a non-judgmental, non-elaborative attitude. Mindfulness trainees practiced meditation at home at least 10 minutes a day, five days a week, over 8 weeks.
The comparison condition met as a group for an equivalent amount of time. Both groups entailed psychoeducation, group discussion, and skills practice, but the “brain training” group practiced mental arithmetic instead of meditation, both in the groups and at home.
All participants completed the Five Facet Mindfulness Questionnaire (FFMQ) and a Stroop task, before and after training. The Stroop task required participants to count the number of words they saw that were presented on a computer screen. Sometimes the words’ meanings interfered with their counting (e.g., when the word “two” appeared three times) or had emotional connotations that could slow their processing speed. Participants needed to ignore the meanings and stay focused on the task.
Electroencephalography (EEG) concurrently measured the participants’ evoked response potentials (ERPs), which are […]
