Abstract
In social psychology, self-monitoring refers to the way in which individuals regulate the manner in which they present themselves to others. High self-monitors are those who are driven to fit in, and strategically adapt their presentation of self to cultivate a specific image of themselves. Low self-monitors are driven more by their personal values and are less likely to adjust their behaviors situationally. One component of self-monitoring is emotional regulation, where high self-monitors are more adept at regulating the presentation of their emotions, (e.g. concealing and faking them), than low self-monitors. We used functional near-infrared spectroscopy (fNIRS) to study how brain activation differs in high and low self-monitors in a self-monitoring task. fNIRS uses two wavelengths of near-infrared light to measure cortical activity by detecting levels of oxygenated hemoglobin. Participants were asked to fill out a self-monitoring questionnaire to determine whether they are high or low self-monitors. Then, while monitoring neural activity with fNIRS, participants viewed a series of positive, neutral, and negative images while completing one of three self-monitoring tasks: inhibiting facial expressions, producing a facial expression consistent with the emotion elicited by the image, and producing an expression inconsistent with the emotion elicited by the image. High self-monitors, being more skilled at emotional regulation, are expected to have an easier time inhibiting facial expressions and producing inconsistent facial expressions in comparison to low self-monitors. We hope to determine the regions of the brain involved with self-monitoring, and to detect any differences between high and low self-monitors while performing this self-monitoring task.

Hello my name is Ambriel Cohen and my study looks at the social psychology phenomenon of self-monitoring using fNIRS, which is a brain imaging technology. fNIRS stands for functional near infrared spectroscopy and it uses two wavelengths of near-infrared light to measure the concentration of oxygenated and deoxygenated hemoglobin in the brain, which gives us an approximation of brain activity.
Specifically in this study, we’re looking at self-monitoring, which is the extent to which one regulates their outward presentation of themselves to produce a certain image of themselves in others. One aspect of this is emotional regulation, in which high self-monitors tend to more easily regulate the presentation of their emotions, while low self monitors tend to do this a little bit less. To study this, we had participants fill out the Snyder self-monitoring scale to determine whether they were high or low self monitors. Then participants were hooked up to an fNIRS machine and viewed a series of images that were positive, neutral, and negative, while doing one of three tasks: either inhibiting all facial expressions; producing an expression that is consistent – that is, the same as the emotion they feel; or making a facial expression that is inconsistent – that is something other than what they actually feel. This third condition of making inconsistent facial expressions is one that especially activates self-monitoring.
When looking at the association between high, low and mid self-monitoring and the task they were completing, our results showed that in the orbital frontal cortex – which is a region that has already been associated with self-monitoring, high self monitors producing inconsistent facial expressions had an interesting trend. There was actually lower brain activation than the mid and low koiself-monitors. This is seen only in the orbital frontal cortex – in some of the other areas like the ventrolateral prefrontal cortex, you don’t see the same trend. This may be due to the fact that high self monitors are more used to practicing their emotional regulation and therefore it doesn’t take as much effort, leading to lower activation.
We also found that there was a significant association between the emotional valence of the images viewed and the expressive tasks participants were completing in brain regions that were associated in emotional processing. This makes sense with the knowledge that these regions are important and emotional processing but it is interesting to see that there is also the connection with emotional expression in these regions. We hope to keep exploring this association, as we keep collecting and analyzing data.
Thank you and let me know if you have any questions!
