Several decades of behavioral research have established that variations in socioeconomic status are related to differences in cognitive performance. Neuroimaging and psychophysiological techniques have recently emerged as a method of choice to better understand the neurobiological processes underlying this phenomenon. Here we present a systematic review of a particular sub-domain of this field. Specifically, we used the PICOS approach to review studies investigating potential relationships between SES and scalp event-related brain potentials. This review found evidence that SES is related to (...) amplitude variations in a diverse range of ERPs: P1, N1, N2, Error-Related Negativities, N400, auditory evoked potentials, negative difference waves, P3 and slow waves. These ERPs include early, mid-latency and late potentials that reflect a broad range of cognitive processes. In this review, all SES effects on ERPs appeared to reflect an impairment or a less efficient form of task-related neural activity for low-SES compared to high-SES individuals. Overall, these results confirm that a wide variety of distinct neural processes with different functional meanings are sensitive to SES differences. The findings of this review also suggest that the relationship between SES and some ERP components may depend on the developmental stage of study participants. Results are further discussed in terms of the current limitations of this field and future avenues of research. (shrink)

The world faces unprecedented challenges because of the Coronavirus Disease 2019. Existing theories of human flourishing and coping efficacy are too broad and general to address COVID-19 unprecedented mental health challenges. This study examined two main objectives, first the associations between psychological outcomes and psychological wellbeing of this phenomenon, and second, moderating and mediating factors emotions, resilience and coping self-efficacy. A nationwide survey was carried out on a Malaysian sample. Participants completed an on-line survey that assessed psychological outcomes, psychological wellbeing, (...) positive–negative emotions, resilience, and coping self-efficacy. The relationship between psychological states and psychological wellbeing was successfully mediated by coping self-efficacy and resilience. Moreover, positive emotion significantly moderated depression and anxiety with psychological wellbeing. Findings highlighted the importance of these factors in developing a dedicated model to be built into the recovery plan to ameliorate the negative impact of COVID-19 on psychological wellbeing. Hence, the Positive Emotion-Resilience-Coping Efficacy Model was developed. (shrink)

Studies have reported high rates of childhood maltreatment among individuals with drug addiction problems; however, investigation about the potentially protective factors to mitigate the effects of maltreatment experiences on motivation to engage in addiction treatment has received less attention. This study aims at exploring the mediating effects of forgiveness and self-efficacy on the association between childhood maltreatment and treatment motivation among drug addicts. A total of 360 male drug addicts were recruited from three mandatory inpatient rehabilitation centers in Malaysia. Participants (...) completed a package of self-report questionnaires including measures of childhood maltreatment experiences, forgiveness, self-efficacy, and motivation for treatment. The analysis conducted using the structural equation model revealed that childhood maltreatment significantly predicted lower treatment motivation, while forgiveness and self-efficacy played a fully mediating role regarding the effect of childhood maltreatment on treatment motivation. In conclusion, these findings suggest that combining the element of forgiveness and self-efficacy in treatment programs appears to benefit the drug addicts with childhood maltreatment history.
