The Influence of Self-Referential Processing on Attentional Orienting in Frontoparietal Networks

Abstract

Self-referential processing refers to the processing of information relevant to oneself and plays an important role in cognition. Behavioral studies have shown that directional cue stimuli have a qualitatively different function during attentional orienting after presentation of the cue associated with the self. However, it is necessary to determine how neural activity is influenced by self-referential processing during attentional orienting. The present study involved establishing an association between non-predictive arrow cues and the “self” during a training task and then investigating the influence of self-referential processing on neural activity during attentional orienting. Enhanced neural activity was observed in cortical midline structures (CMS) during the use of self- vs. neutral-arrow cues, which suggests that the arrow associated with the “self” triggered self-referential processing during attentional orienting due to the experiences of the participant in the training task. Comparison of obtained under the incongruent and congruent conditions revealed a qualitative difference in neural activities between the self- and neutral-arrow cues associated with attentional orienting. Furthermore, when the neutral-arrow cue was treated as a baseline condition, neural activity was reduced in the frontoparietal attention networks by self-referential processing under the incongruent condition, but it was enhanced under the congruent condition. Thus, the stimulus modulated subsequent attentional neural processes after being associated with the self as a cue, which indicates that this process may be triggered by self-reference to automatically and effectively capture information. Our findings extend those of previous behavioral studies of neural activity, suggesting that directional cues were qualitatively influenced by self-referential processing, and showed different functions during attentional orienting. Moreover, the present study provides important evidence of how self-referential processing affects attentional orienting in the frontoparietal network.Highlights Enhanced activity was observed in CMS due to self-referential processing.The influence of self-referential processing differed in the frontoparietal network.Activity was enhanced by self-referential processing under the congruent condition.Activity was reduced by self-referential processing under the incongruent condition.

RETRACTED: Therapeutic interventions impact brain function and promote post-traumatic growth in adults living with post-traumatic stress disorder: A systematic review and meta-analysis of functional magnetic resonance imaging studies

“… Wei et al (2017) , for example, have explored how a cohort of adults exposed to the Tianjin explosion incident exhibited greater activation of the left hemisphere of the dorsolateral prefrontal cortex (L dlPFC), which they identify as a crucial region of interest (ROI) implicated in PTG because it regulates distressing affect and irregular heart rate. Similar findings about the L dlPFC were presented by Nakagawa et al (2016) after assessing survivors of the East Japan Great Earthquake, adding that activation of both hemispheres of the anterior cingulate cortex (L/R ACC) was similarly important because these ROIs help individuals with the synthesis of thoughts and feelings into a self-referential worldview and belief system ( Yoshimura et al, 2009 ; Yang et al, 2012 ; Nejad et al, 2013 ; Wagner et al, 2015 ; Zhao et al, 2018 ). One might observe that highlighting the L dlPFC over other prefrontal brain regions in the process of PTG may appear odd because it is often the ventromedial prefrontal cortex (vmPFC) that facilitates self-referential cognition in humans ( D’Argembeau, 2013 ; Konu et al, 2020 ; Park et al, 2020 ; Stendardi et al, 2021 ; Yin et al, 2021 ).…”

Altered resting-state neural networks in children and adolescents with functional neurological disorder

“…The precuneus is involved in emotion regulation, self-agency, and self-referential processing: the spontaneous causal attributions (self-agency or lack of self-agency) that an individual makes in relation to events that elicit positive and negative emotions ( Loeffler et al, 2018 ). Self-referential processing also affects episodic memory: the recall of memories is better when it is related to the self ( Zhao et al, 2018 ). Of particular interest here is a recent EEG study showing the precuneus to be overactive in children with mixed FND ( Kozlowska et al, 2018 ).…”

Spatio-temporal brain dynamics of self-identity: an EEG source analysis of the current and past self

“…Apps et al ( 2012 , 2015 ) have found that a set of unimodal and multimodal areas are sensitive to self-adulthood identification. It has been shown that fronto-parietal attentional networks could be recruited by the presence of self-related stimuli (Humphreys and Sui 2016 ; Zhao et al 2018 ). Hence, the role of the inferior parietal areas deserves more dedicated studies to clarify whether it entails a static representation of the physical identity.…”
