Introduction:
Individuals who experience high levels of anxiety often struggle to manage their emotions due to their heightened self-focused attention, which can lead to various problems. Consequently, individuals with high anxiety struggle to fully benefit from positive events and are significantly affected by negative events due to excessive analytical rumination. However, there is a lack of neuroimaging investigation into how this self-focused attention occurs based on positive and negative emotions. Thus, the current study aimed to elucidate the effect of positive and negative self-talks on functional connectivity in highly anxious individuals.
Methods:
Thirty-four individuals with high level of anxiety (HA, n= 18; BAI, mean=24.3, SD=6.07) and low level of anxiety (LA, n= 16; BAI, mean=6.56, SD=1.90) were scanned using functional magnetic resonance imaging at 5-min self-respect and self-criticism tasks. A seed-to-voxel analysis was conducted using the seeds in the posterior cingulate cortex (PCC) for the default mode network and self-referential processes, the anterior cingulate cortex (ACC) for emotion regulation, and the nucleus accumbens (NAcc) and insula for the reward-motivation network. We conducted 2 (group: HA and LA) X 2 (task: self-respect and self-criticism) mixed ANOVA to identify the main effect of group and the interaction effect of group x task. Identified brain activities were correlated with psychological scales including the Level of Self-Criticism Scale and the Connor Davidson Resilience Scale.
Results:
In the self-respect task, the HA group showed significantly higher connectivity strength between the insula and left supramarginal gyrus, as well as between the insula and left cerebellum, whereas the LA group showed significantly higher connectivity strength between the ACC and left frontal pole. In the self-criticism task, the HA group showed significantly higher connectivity strength between the PCC and right middle frontal gyrus, and between the insula and left supramarginal gyrus, whereas the LA group showed significantly higher connectivity strength between the ACC and left middle frontal gyrus. Moreover, the group x task interaction effect was identified in the connection between the insula and right cerebellum, as well as between the NAcc and left pallidum. Lastly, connectivity between the insula and left cerebellum in the self-respect task, connectivity between the PCC and right middle frontal gyrus, and connectivity between the insula and left supramarginal gyrus in the self-criticism task were correlated with some psychological scale scores.
Conclusions:
This study was conducted to elucidate differences in the modulation of functional connectivity by positive and negative self-talk in highly anxious individuals compared to low-anxious individuals. Our findings suggest that, regardless of the task, highly anxious participants exert more effort to activate the reward-motivation network and default mode network, whereas they may not adequately regulate their emotions when exposed to both self-respect and self-criticism. Furthermore, correlations with psychological variables imply that the neuronal mechanisms of anxious individuals might affect other basic psychological needs, such as resilience.
