Gender Differences in the Relationship Between Short-Form Video Addiction and Adolescent Depression: The Mediating Role of Attentional Bias.

Previous studies have shown that short-form video addiction (SVA) is a significant predictor of adolescent depression. However, little is known about the mediating mechanisms. Guided by the Interaction of Person-Affect-Cognition-Execution model, this study aimed to investigate the relationship between SVA and depression among Chinese adolescents and to examine the mediating role of attentional bias toward positive information (API) and negative information (ANI), including potential gender differences.

Reduce negative life events to Increase satisfaction: A daily diary study on the relationship between negative life events and life satisfaction.

Life satisfaction refers to an individual' s cognitive evaluation of the overall quality of their life considering the various aspects therein. Although the existing research has demonstrated the between-person relationship between negative life events and life satisfaction based on retrospective measures, less is known about this relationship at the within-person level. A daily diary method could examine this within-person relationship and decrease systematic recall biases.

Neural basis responsible for effect of grit on procrastination: The interaction between the self-regulation and motivation neural pathways.

Procrastination has a detrimental impact on academic performance, health, and subjective well-being. Previous studies indicated that grit was negatively related to procrastination. However, the underlying neural basis of this relationship remains unclear.

Neural basis underlying the relation between internet addiction tendency and sleep quality: The intrinsic default-mode network connectivity pathways.

Internet addiction (IA) tendency is considered an addictive behavior that results from excessive Internet use, and severely affecting an individual's physical health, emotion, and sleep. Although previous studies indicated that IA tendency was negatively correlated with sleep quality, the underlying neural basis of this relationship remained unclear. To address this issue, we utilized resting-state functional connectivity (RSFC) analysis to identify the neural pathways of the relationship between IA tendency and sleep quality.

Psychological resilience mediates the association of the middle frontal gyrus functional connectivity with sleep quality.

Psychological resilience is characterized as the ability to recover from stress, which is essential for sleep quality. However, the neurological underpinnings of psychological resilience and the neural substrates of the links between psychological resilience and sleep quality in healthy brains remain not well understood. To address these issues, we adopted the method of resting-state functional connectivity (rs-FC) analysis in 144 young college students.

The role of valence, arousal, stimulus type, and temporal paradigm in the effect of emotion on time perception: A meta-analysis.

Anecdotal experiences show that the human perception of time is subjective, and changes with one's emotional state. Over the past 25 years, increasing empirical evidence has demonstrated that emotions distort time perception and usually result in overestimation. Yet, some inconsistencies deserve clarification.

Negative emotions and brain: Negative emotions mediates the association between structural and functional variations in emotional-related brain regions and sleep quality.

Importance And Study Objective: Emotion plays an important role in sleep quality, meanwhile, poor sleep quality is usually correlated with high negative emotions (NES). However, less is known about the neural basis for NES and the underlying mechanism for how NES affect individuals' sleep quality in the health brain. The present study combined voxel-based morphometry and resting-state functional connectivity analysis to identify the relationship between brain regions and NES, and then explored how NES-related brain structures are related to sleep quality in a large sample of normal young adults.

Resting-state functional connectivity of the sensory/somatomotor network associated with sleep quality: evidence from 202 young male samples.

Previous neuroimaging studies have demonstrated that sleep is associated with brain functional changes in some specific brain regions. However, few studies have examined the relationship between all possible functional connectivities (FCs) within the sensory/somatomotor network (SSN) and the sleep quality of young male samples. The SSN consists of two motor cortices and is known to play a critical role in sleep.

Association of white matter volume with sleep quality: a voxel-based morphometry study.

Many studies have focused on the gray matter volume associated with sleep quality, little is known about the relationship between white matter volume and sleep quality. Brain white structure is a crucial component in the structural neuroanatomy. Therefore, in this study, we investigated the association between white matter volume and sleep quality.

The gray matter volume of bilateral inferior temporal gyrus in mediating the association between psychological stress and sleep quality among Chinese college students.

The role of brain regions in the relationship between psychological stress and sleep quality is unclear. This study investigates the neuroanatomical basis of the association between psychological stress and sleep quality. Data were collected using the Pittsburgh Sleep Quality Index, the Psychosomatic Tension Relaxation Inventory, and voxel-based morphometry among 318 healthy students.

The Effects of Angry Expressions and Fearful Expressions on Duration Perception: An ERP Study.

Little is known about the electrophysiological basis of the effect of threat-related emotional stimuli with different motivational direction on duration perception. Thus, event-related potentials were employed to examine the effects of angry expressions and fearful expressions on perception of different duration (490-910 ms). Behavioral results showed there was a greater underestimation of the duration of angry expressions (approach-motivated negative stimuli) than fearful expressions (withdrawal-motivated negative stimuli), compared with neutral expressions.
