拖延的认知神经机制与基因:行为-脑-基因的多角度研究
Neural mechanisms and gene of procrastination based on a behavior-brain-gene perspective
摘要
Abstract
Established as a widespread problematic behavioral and a stable individual tendency across time and different contexts,procrastination is harmful to the procrastinator's psychological,physical,and financial well-being.Given the cognitive mechanism of procrastination is unclear and methodologies in previous studies was dated,we are developing studies from a behavior-brain-gene perspective,using a multi-modal MRI (Task,Resting,VBM and DTI) methodology and considering HTR2B gene as a breakthrough direction,to reveal the cognitive mechanisms,neural mechanisms and hereditary basis of procrastination systematically.In addition,we intended to design interventions for procrastination as well.Our studies will includes four aspect:(1) from a behavioral perspective,we are exploring the cognitive mechanism of deciding to procrastinate by combining paradigm of dread studies with intertemporal choice task;(2) from a neural perspective,we are using a multi-modal MRI methodoloty to reveal the neural mechanism of procrastination;(3) from a genetic perspective,we are utilizing molecular genetic methods and taking the HTR2B gene as our targeted gene to disclose the genetic mechanism of procrastination and test a mediating role of neural structure or function between hereditary basis and procrastination;(4)Considering intervention for procrastination and malleability of brain,we also intend to design training program to reduce procrastination and test procrastination related neural plasticity.关键词
