Personality and Nomophobia: A Moderated Mediation Model of Self-Esteem and Non-Self-Determined Solitude

Background:With the development of information technology,mobile phone has brought much convenience to people’s lives but also caused many negative consequences due to excessive use,such as mobile phone addiction and nomophobia.Previous studies have explored the relationship between the Big Five Personality and proble-matic mobile phone use(PMPU).However,they focus on mobile phone addiction.Although there is a correlation between nomophobia and mobile phone addiction,the psychological structure is different.Therefore,it is neces-sary to explore the relationship between personality and nomophobia and the underlying mechanism.This study aims to examine the relationship between Big Five Personality and nomophobia,then construct a moderated mediation model to explore the mediation effect of solitude between Big Five Personality and nomophobia,as well as the moderation effect of self-esteem.Method:Data from 678 college students(351 females,51.77%)were collected.Participants completed the Big Five Personality Inventory,Solitude Behavior Scale,Nomophobia Scale and Self-esteem Scale.Analyses were conducted via mediation and moderated mediation.Results:Structural equation models revealed that solitude mediated the relationship between neuroticism and nomophobia.The results showed that neuroticism positively predicted solitude,which in turn positively predicted nomophobia.Four types of solitude partially mediated the relationship between neuroticism and nomophobia.We also found that self-esteem moderated the association between neuroticism and non-self-determined solitude.It is note-worthy that high self-esteem cannot protect people from negative factors.However,because of its characteristics,it is easy to receive more social information,and people high in neuroticism are sensitive to negative social infor-mation.It may cause maladaptive behavior.Conclusion:Findings demonstrated a process through which neu-roticism relates to nomophobia and a context under which these relationships may have occurred.

College Students’Academic Stressors on Mental Health during the COVID-19 Pandemic: A Comparison between Graduating Students and Non-Graduating Students

The study aimed to investigate the influence of academic stressors on mental health and the mediating effect of social support and self-identity among college students and further studied the difference between the graduating students and non-graduating students during the COVID-19 Pandemic.Recruiting 900 college students as sub-jects,used the college students’academic stressors questionnaire,social support questionnaire,self-identity scale and depression anxiety stress scales(DASS-21).The results showed that:(1)The college students’academic stressor posi-tively predicted mental health;(2)Social support and self-identity mediated the relationship;(3)The model also held when academic stressors was replaced by work stressor,but there were differences between the graduating and non-graduating students;(4)The direct effect work stressor on mental health in the graduating group was not significant;(5)The non-graduating students’work stressor could not predict mental health through social support.

Evolutionary Psychology： How Psychological Mechanisms Shaped by Natural Selection for Ancestral Environments Produce Current Behaviours

The central purpose of this paper is to explain how Darwin′s theory of evolution by natural selection can be used in understanding current human behaviour. First, Darwin′s logic is briefly described. Development is an important issue when applying evolutionary theory to human behaviour. The notion of innate developmental organization of psychological mechanisms is introduced. The possible social and political outcomes produced when different levels of innate developmental organization are paired with different beliefs about it are considered. The notion of psychological mechanisms as evolved adaptations is considered in some detail. Then I discuss different ways evolutionists think about how genes are involved in the development of adaptations. The paper concludes with a framework for considering how ancestral adaptations function in current environments and outlines some ways of studying them. In China and many other parts of the world people desire a more harmonious society. I hope that this paper will be of some small help in achieving this great task.

Neural correlates of audio-visual modal interference inhibition investigated in children by ERP

In order to detect cross-sectional age characteristics of cognitive neural mechanisms in audio-visual modal interference inhibition,event-related potentials(ERP) of 14 10-year-old children were recorded while performing the words interference task.In incongruent conditions,the participants were required to inhibit the audio interference words of the same category.The present findings provided the preliminary evidence of brain mechanism for the children's inhibition development in the specific childhood stage.
