“The quality of your attention determines whether you are present and alert, or mentally and/or emotionally distracted. The good news is that it’s possible to train your attention and gain the associated benefits, and practicing mindfulness offers one of the most accessible and effective approaches.” – Deborah David
One of the primary effects of mindfulness training is an improvement in the ability to pay attention to the task at hand and ignore interfering stimuli. This is an important consequence of mindfulness training and produces improvements in thinking, reasoning, and creativity. The importance of heightened attentional ability to the individual’s ability to navigate the demands of complex modern life cannot be overstated. It helps at work, in relationships, or simply driving a car. Being effective socially demands accurately assessing the emotional states of other people. This requires attention to the non-verbal subtle signals of facial expression, body posture, and gestures. In this context, attention to these subtleties is a prerequisite for appropriate interactions. As a result, mindfulness improves social interactions.
There is evidence that mindfulness training improves attention by altering the brain. It appears That mindfulness training increases the size, connectivity, and activity of areas of the brain that are involved in paying attention. A common method to study the activity of the nervous system is to measure the electrical signal at the scalp above brain regions. Changes in this activity are measurable with mindfulness training. One method to observe information processing in the brain is to measure the changes in the electrical activity that occur in response to specific stimuli. These are called evoked potentials or ERPs. The signal following a stimulus changes over time. The fluctuations of the signal after specific periods of time are thought to measure different aspects of the nervous system’s processing of the stimulus.
The N100 response in the evoked potential (ERP) is a negative going response occurring around a tenth of a second following a visual stimulus presentation. The N100 response has been associated with the engagement of visual attention. So, the N100 response is often used as a measure of brain attentional engagement with the larger the negative change the greater the attentional focus. The N200 response in the evoked potential (ERP) generally follows shortly after the N100 response. It is a negative change that is maximally measured over the frontal lobe. The N200 response has been associated with the resolution of conflicting response expectations. The P300 response occurs around a quarter of a second following the stimulus presentation. It is a positive change that is maximally measured over the central frontal lobe. The P300 response has been associated with holding back expected actions (response inhibition).
The relationship of mindfulness to the brain’s processing of social/emotional stimuli was investigated in today’s Research News article “Trait Mindfulness Predicts Efficient Top-Down Attention to and Discrimination of Facial Expressions.” See:
or see summary below. Quaglia and colleagues recruited college students and measured their levels of mindfulness, social anxiety, and attentional control. The participants’ EEG was measured while performing a go/no-go task in which they were asked to press a button to a picture of a face if it expressed a target emotion (happy, neutral, or fearful) and refrain from responding if a different emotion was being portrayed.
They found that the higher the levels of the students’ mindfulness the faster they responded to the faces. In addition, they found that the higher the levels of mindfulness the larger the N100 and N200 responses. With the P300 response, high levels of mindfulness were only found to be associated with larger responses on no-go trials, when they withheld a response to a non-target emotion. There was no difference in the P300 response to go trials.
These results suggest that mindfulness improves attention to emotionally significant stimuli and does so by heightening the brain’s response to these stimuli.. This is supported by the faster response times by highly mindful participants. In, addition, the neural responses indicate better processing with the heightened N100 and N200 responses indicating greater attention and better decision processes while the heightened P300 response indicating better ability to withhold responses to stimuli when appropriate. Hence, the results suggest that attention to and responding to emotionally significant stimuli is improved with mindfulness. This may be one of the mechanisms by which mindfulness improves emotion regulation in general.
So, pay attention with mindfulness.
“Mindfulness refines our attention so that we can connect more fully and directly with whatever life brings. So many times our perception of what is happening is distorted by bias, habits, fears, or desires. Mindfulness helps us see through these and be much more aware of what actually is.” – Sharon Salzberg

Abstract
In social situations, skillful regulation of emotion and behavior depends on efficiently discerning others’ emotions. Identifying factors that promote timely and accurate discernment of facial expressions can therefore advance understanding of social emotion regulation and behavior. The present research examined whether trait mindfulness predicts neural and behavioral markers of early top-down attention to, and efficient discrimination of, socioemotional stimuli. Attention-based event-related potentials (ERPs) and behavioral responses were recorded while participants (N = 62; White; 67% female; Mage= 19.09 years, SD = 2.14 years) completed an emotional go/no-go task involving happy, neutral, and fearful facial expressions. Mindfulness predicted larger (more negative) N100 and N200 ERP amplitudes to both go and no-go stimuli. Mindfulness also predicted faster response time that was not attributable to a speed-accuracy trade-off. Significant relations held after accounting for attentional control or social anxiety. This study adds neurophysiological support for foundational accounts that mindfulness entails moment-to-moment attention with lower tendencies toward habitual patterns of responding. Mindfulness may enhance the quality of social behavior in socioemotional contexts by promoting efficient top-down attention to and discrimination of others’ emotions, alongside greater monitoring and inhibition of automatic response tendencies.
