时间压力、属性数量影响决策信息加工的研究

本研究采用决策研究的信息板技术,以模拟的购房决策为实验任务,探讨了时间压力（高时间压力、低时间压力、无时间压力）和属性数目对决策者信息加工的影响。研究共包括两个实验。预备实验通过计算机编制的模拟购房决策任务,测得了不同时间压力状态下的决策时间。正式实验是在预备实验的基础上,探讨时间压力和属性数目对决策信息加工的影响。结果显示：（1）在选择时间和信息搜索深度上,时间压力和属性数目主效应以及两者交互作用显著;（2）在信息搜索模式上,时间压力和属性数目的主效应显著,但交互作用不显著。无时间压力和低时间压力状态下,决策者多采用以选项为主的决策策略。而高时间压力状态下,决策者为了适应严格的时间限制,多采用以属性为主的决策策略。

Influences of Time Pressure, and Number of Attributes on Information Processing in Decision Making

The research employed the technology of information board,used the housing purchase as the experimental task,and explored the influences of time pressure（high time pressure,low time pressure and no time pressure） and the numbers of property on the decision makers＇ information processing.The study included two experiments.Preparative experiment tested the time of decision making under different time pressure via the simulated housing purchase tasks programmed with the computer.Formal experiment explored the influences of time pressure and the numbers of Attributes on decision making information processing,on the basis of preparative experiment.The results showed that（1） in the depth of selected time and information search,time pressure and the numbers of property had a significant main effect and crossing effect.（2） On the mode of information search,time pressure and numbers of property had a significant main effect,but no significant crossing effect.And decision makers usually applied decision making strategy according to choices under no and low time pressure.But they mostly applied decision making strategy according to properties,for the sake of strict time restriction under high time pressure.
