The Mechanism Of Action Of The Types Of Clue And The Risk Level To The Decision-making Tendency And Evaluation Of Its Result

Traditional risk decision-making research still do studies on situations(Event1or Event2) thatone must make a choice between two alternatives. Currently,a new field of the risk decision-making hascaught the researchers attention,which suggests that we would not have to make a choice instead ofchoosing to accept or give up both of them.. The former belongs to merit-based decision-making, the latteris named the accept or abandon pattern the decision making. Merit-based decision-making and acceptand abandon pattern decision making are different, so the decision-making process of neural mechanismsbetween them probably different. In this thesis, we use the ERP technology to explore the neuralmechanisms of “to accept or to abandon”decision-making in the condition that whether there is a externalclue in the risk situation. In this thesis, we design two experiments: Experiment1represents non-cluesituation; Experiment2represents situations with clues.In the general experiment, Experiment3is represents the risk decision feedback mechanismunder no clues, and Experiment1represents the neural mechanism of risk decision propensity under noclues; Experiment3is represents the risk decision feedback mechanism with clues, and Experiment2(B)represents the neural mechanism of risk decision propensity under clues.Finally,we make a comparisonbetween Experiment3and Experiment2,and do the same to the Experiment3with the Experiment3.Thepurpose of the former experiment is to explore the difference of the wave amplitudes on FRN、N1、P3under the venture decision feedback, the latter one focus on the difference of the wave amplitudes betweenN1and P1under the risk decision propensity.The Statistics results show that the main effect is firstly related to decision potency of the FRN,N1, P3component amplitude in the no clues conditions were significantly different,and the differenceunder the condition of clues is not significant. Description, FRN, N1, P3components and intrinsic cues,factors, feedback, attention, probability by memory etc.Brain regions activated have frontal, central andparietal regions. The decision feedback mechanism for conflict were significantly, there is no relationshipbetween external cuing effect, prove FRN, N1, P3belong to psychological endogenous components,eventually reached the same conclusions with previous. Secondly, and decisions tend to related components: N1, P1, commonly known as clues to the effectiveness of the indicators, at the same time of non spatialattention direction.According to the experimental I and II, the amplitude of P1in significant wirelesscable decision-making under presence of clues risk decision tendency, the significance of N1, P1withclues conditions between, no significant under no clues.Frontal brain regions activated with frontalarea,central region, temporal region, occipital area.which belongs to the exogenous component of decisionmaking.
