Spontaneous microstates related to effects of low socioeconomic status on neuroticism

Abstract

Individuals with high neuroticism had the decreased control functions of anterior cingulate cortex (ACC) over amygdala (emotion regions) and low socioeconomic status (SES) had negative effects on the functions of ACC. Based on these, we hypothesized that the decreased functions of ACC might make individuals with low SES had high level of neuroticism. According to the score of objective SES (OSES) and subjective SES (SSES) scales, subjects were divided into four groups (low SSES, high SSES, low OSES and high OSES) to investigate the roles of dynamic characteristics related to the ACC in the relationships between SES and neuroticism using resting-state EEG (RS-EEG) microstates analysis. It had been found that RS-EEG microstates can be divided into four types (MS1, MS2, MS3 and MS4) and the MS3 was related cingulo-opercular brain networks (including ACC and anterior insular). As our prediction, SSES had direct effects on neuroticism relative to OSES. Moreover, the neuroticism for low SSES was positively related to the occurrence and contribution of MS3, as well as the possibilities of transitions between MS3 and MS1. Based on these, we thought that low-SSES individuals might be more difficult to inhibit the negative emotions, especially inhibit the spontaneous thoughts related to these emotions.

Gender difference in the relationship between personality traits and changes in depressive symptoms before and after the COVID-19 outbreak: A follow-up study among Chinese adults

“…Firstly, our findings suggest a positive correlation between neuroticism, openness, and changes in depressive symptoms, which aligns with previously reported studies. It is well-established that individuals with high neuroticism are more prone to sadness, anxiety, self-consciousness, and vulnerability and are more likely to experience negative emotions ( Guo et al, 2020 ). Neuroticism is also an independent predictor of depressive symptoms and anxiety ( Van Loey et al, 2014 ).…”

Influence of depressive disorders, stress, and personality traits on quality of life after cochlear implantation

“…Presumably, this is because psychosocial symptoms are more strongly presented in the WHOQOL-BREF than in the NCIQ. It is well known that individuals with high neuroticism are more prone to sadness, anxiety, vulnerability, and negative emotions [ 48 ]. Additionally, previous research has highlighted neuroticism as a predictor of depressiveness and perceived stress [ 25 , 26 ].…”

EEG Microstates in Social and Affective Neuroscience

“…Microstate analysis of continuous EEG has been used to illuminate the sources of individual differences in socio-affective traits, in domains such as aggression (Kleinert and Nash 2022 ), anxiety (Schiller et al 2019b ; Du et al 2022 ; Nash et al 2023 ), approach vs. withdrawal tendency (Takehara et al 2020 ; Kaur et al 2020 ), disgust sensitivity (Li et al 2021 ), empathy (Zhang et al 2021 ), personality (Zanesco et al 2020 ; Guo et al 2020 ; Tomescu et al 2022 ), prosociality (Schiller et al 2020b ), religious belief (Schlegel et al 2012 ; Nash et al 2022 ), or somatic awareness (Pipinis et al 2017 ; Tarailis et al 2021 ; Zanesco et al 2021a ). The majority of these studies have relied on regression or correlation analysis to uncover associations between features of the prototypical microstate classes (e.g., duration, occurrence, coverage, transition probabilities; see Box 4 ) and socio-affective traits (see Fig.…”
