Introduction: Abnormal behavior can cause harm or loss to oneself, the family, and society and may be related to psychological endurance levels. With early identification and early intervention, the occurrence of harm can be prevented and the loss can be reduced. Now there is no clear definition of psychological endurance levels and no accurate measurement tools yet.

In this study, 2 experiments were conducted to investigate whether motivation and positive affect can alleviate ego depletion and to elucidate their possible mechanisms. In Experiment 1, a crossing-out-letter task was adapted to reach an ego depletion state for Chinese participants. Participants were then randomly assigned to the extrinsic motivation group, the positive affect group or the depletion control group.

As children become proficient readers, there are substantial changes in the eye movements that subserve reading. Some of these changes reflect universal developmental factors while others may be specific to a particular writing system. This study attempts to disentangle effects of universal and script-dependent factors by comparing the development of eye movements of English and Chinese speakers.

Article Synopsis
  • The study analyzes over 3 million genetic variations from the International HapMap Project to identify regions of the human genome that have undergone positive natural selection.
  • Using advanced methods, researchers pinpointed over 300 candidate regions, specifically narrowing down to 22 strong areas for further scrutiny.
  • The analysis highlights 26 specific gene variations under positive selection, demonstrating similar evolutionary pressures in related genes across different populations, including regions tied to virus infection and traits like skin pigmentation and hair follicle development.

We describe the Phase II HapMap, which characterizes over 3.1 million human single nucleotide polymorphisms (SNPs) genotyped in 270 individuals from four geographically diverse populations and includes 25-35% of common SNP variation in the populations surveyed. The map is estimated to capture untyped common variation with an average maximum r2 of between 0.

The International HapMap Consortium has developed the HapMap, a resource that describes the common patterns of human genetic variation (haplotypes). Processes of community/public consultation and individual informed consent were implemented in each locality where samples were collected to understand and attempt to address both individual and group concerns. Perceptions about the research varied, but we detected no critical opposition to the research.
