Brain Responses to Peer Feedback in Social Media Are Modulated by Valence in Late Adolescence

Abstract

Previous studies have examined the neural correlates of receiving negative feedback from peers during virtual social interaction in young people. However, there is a lack of studies applying platforms adolescents use in daily life. In the present study, 92 late-adolescent participants performed a task that involved receiving positive and negative feedback to their opinions from peers in a Facebook-like platform, while brain activity was measured using functional magnetic resonance imaging (fMRI). Peer feedback was shown to activate clusters in the ventrolateral prefrontal cortex (VLPFC), medial prefrontal cortex (MPFC), superior temporal gyrus and sulcus (STG/STS), and occipital cortex (OC). Negative feedback was related to greater activity in the VLPFC, MPFC, and anterior insula than positive feedback, replicating previous findings on peer feedback and social rejection. Real-life habits of social media use did not correlate with brain responses to negative feedback.

Keywords: brain; fMRI; feedback; late adolescence; peers; social media.

FIGURE 1
An example screenshot (translated from Finnish to English for descriptive purposes) of the mock Facebook environment used in the study. The response of the participants to a controversial statement is presented as a “post” in a generic Facebook group. The post is followed by four comments from perceived peers. In this example, the participant has responded with “agree” to a controversial statement and has received negative peer feedback to their “post” from peers.

A schematic illustration (translated from Finnish to English) of the procedure of the study. In the sequence of an example trial, where the participants are presented with a controversial statement, they respond with “agree,” and then receive negative peer feedback from peers.

Brain responses to emotionally valenced vs. neutral stimuli. (A) Brain regions showing significantly stronger activity in response to viewing controversial (valenced) statements than to viewing neutral statements. (B) Brain regions showing on average significantly stronger activity in response to positive or negative peer feedback (i.e., valenced feedback) than to neutral feedback. Voxel-level family-wise error corrected p < 0.05, cluster size > 100 voxels for both.

Brain responses to negative vs. positive peer feedback. Brain regions showing significantly higher activity in response to negative than positive peer feedback (yellow areas), and vice versa (red areas). Cluster-level family-wise error corrected p < 0.05, cluster size > 100 voxels.
