Research advances on the duration aftereffect / 生理学报

Recent sensory history plays a critical role in the perception of event duration. For example, repetitive exposure to a particular duration leads to the distortion of subsequent duration perception. This phenomenon, termed duration adaptation, induces a robust repulsive duration aftereffect. In particular, adaptation to relatively long sensory events shortens the perceived duration of a subsequent event, while adaptation to relatively short sensory events lengthens the perception of subsequent event durations. This phenomenon implies the plasticity of duration perception and offers important clues for revealing the cognitive neural mechanism of duration perception. Duration aftereffect has received more and more attention in recent years. In this review, we introduce recent research advances in our understanding of duration aftereffect, especially with regards to its manifestations, origin, and cognitive neural mechanisms. We also propose possible directions for future research. In sum, we posit that studies on the duration aftereffect phenomenon are helpful in understanding general duration perception, and as such, should receive more attention in future.

Research on mental health of landless farmers / 中国康复理论与实践

@#ObjectiveTo explore the mental problems of landless farmer for improving their mental health.MethodsThe questionnaire was used in a survey of 322 landless farmers in east and west China and the impacts of demographic and psychosocial factors on mental problems of landless farmers were also analyzed.ResultsThe landless farmers in China had little symptoms of mental problems, but the status of mental health for landless farmers in west China was worse that those in east China. The different mental symptoms of landless farmers were affected by demographic and psychosocial factors in different degrees.ConclusionThe study reveals that special attention and concern might be attached to the employment and the vocation training of landless farmers, especially to the landless farmers in west China.
