Abstract

Research Highlights Intra‐individual response time variability (IIRTV) during cognitive performance is increasingly recognized as an important indicator of attentional control (AC) and related brain region function. However, what determinants contribute to preschoolers’ IIRTV received little attention. The present study explored the interaction of dopaminergic polygenic composite score (DPCS) and the parent–child relationship in relation to preschoolers’ IIRTV. In the initial sample, 452 preschoolers (M age = 5.17, SD = 0.92) participated in the study. The modified Flanker task was used to evaluate children's IIRTV and their parents were requested to complete the Parent–Child Relationship Scale to assess the parent–child relationship (closeness/conflict). DNA data were extracted from children's saliva samples, and a DPCS was created by the number of COMT, DAT1, and DRD2 alleles associated with lower dopamine levels. Results showed that DPCS significantly interacted with the parent–child closeness to impact preschoolers’ IIRTV. Specifically, preschoolers with higher DPCS exhibited lower IIRTV under higher levels of the parent–child closeness, and greater IIRTV under lower levels of the parent–child closeness compared to those with lower DPCS, which supported the differential susceptibility theory (DST). A direct replication attempt with 280 preschoolers (M age = 4.80, SD = 0.86) was conducted to investigate whether the results were in accordance with our exploratory outcomes. The interactive effect of DPCS and the parent–child closeness on IIRTV was confirmed. Additionally, the significant interactive effect of DPCS and the parent–child conflict on IIRTV was found in the replication study. The findings indicate that preschoolers’ IIRTV, as an indicator of AC and related brain region function, is influenced by the interactions of dopaminergic genotypes and the parent–child relationship. We investigated the Gene × Environment mechanism to underline the intra‐individual response time variability as an indicator of attentional control (AC) in Chinese preschoolers. Dopaminergic polygenic composite score (COMT, DAT1, and DRD2) interacted with the parent–child relationship to predict preschoolers’ intra‐individual reaction time variability. A direct replication attempt has been conducted, and the results were in accordance with our exploratory outcomes, which increased the credibility of the present findings. The findings highlight the importance of considering precursors, including polygenic and environmental factors, which contribute to the development of early cognitive performance such as AC.

Abstract

Based on the biopsychosocial model of Internet addiction, this study tested a moderated mediation model of familial (i.e., perceived autonomy-supportive parenting), psychological (i.e., need satisfaction) and biological (i.e., baseline respiratory sinus arrhythmia, RSA) factors to investigate how they jointly impact Internet addiction in emerging adults; specifically, we explored whether RSA moderated the mediating effect of need satisfaction on the relation between perceived autonomy-supportive parenting and Internet addiction. A total of 146 Chinese undergraduates completed questionnaires on autonomy-supportive parenting, need satisfaction and Internet addiction. RSA data were also obtained. Path analysis was used to test the proposed mediation and moderated mediation models. The results indicated that while the impact of perceived autonomy-supportive parenting on Internet addiction was mediated by need satisfaction, RSA moderated this indirect effect. The indirect effect of autonomy-supportive parenting on Internet addiction via need satisfaction was much stronger in adults with low levels of RSA than in those with high levels of RSA. Our findings highlight the joint impact of biological, psychological, and social-environmental factors on Internet addiction and have important implications for the prevention of and intervention against emerging adults' Internet addiction., Author(s): Danni Liu [sup.1] , Zhenhong Wang [sup.1] , Xiaohui Yang [sup.1] , Yuewen Zhang [sup.1] , Runzhu Zhang [sup.1] , Shanyan Lin [sup.1] Author Affiliations: (1) grid.412498.2, 0000 0004 [...]

Abstract

As an important phase-change material, GeTe has many high-pressure phases as well, but its phase transitions under pressure are still lack of clarity. It is challenging to identify high-pressure GeTe crystal structures owing to the phase coexistence in a wide pressure range and the reversibility of phase transitions. Hence, first-principles calculations are required to provide further information in addition to limited experimental characterizations. In this work, a new orthorhombic Cmca GeTe high-pressure phase has been predicted via the CALYPSO method as the most energetically favorable phase in the pressure range between ∼30 and ∼38.5 GPa, which would update the GeTe high-pressure phase transition sequence. The crystal structure of the Cmca phase is composed of alternate stacking puckered layers of Ge six-membered rings and Te four-membered rings along the b direction. The high density of states near the Fermi level and delocalization of electrons from the two-dimensional electron localization function indicate a strong metallic property of the Cmca phase. Electron–phonon coupling calculations indicate that the Cmca phase is superconductive below ∼4.2 K at 35 GPa. The simulated x-ray diffraction pattern of the Cmca phase implies that this phase might coexist with the Pnma-boat phase under high pressure. These results offer further understanding on the high-pressure structural evolution and physical properties in GeTe and other IV–VI semiconductors. [ABSTRACT FROM AUTHOR]
