线索折扣效应研究概述

A Review of the Research on the Cue-Depreciation Effect

线索折扣效应是指更残缺刺激的呈现使部分残缺的同一刺激的识别发生困难。目前,错误假设说、竞争激活模型、失匹配假说和特征调节搜索模型是解释线索折扣效应较有影响的四种理论。已有研究表明,初始点、注视时间、学习方式、策略使用、个体差异、空白间隔和呈现顺序均会影响线索折扣效应的产生。本文结尾从加强研究基础理论、精确使用测量指标、逐步提高应用价值以及大力拓展未知领域四个方面探讨了该领域未来发展的可能趋势。

The cue-depreciation effect is a degraded version of previously exposed stimuli which is less likely to be identified if it is preceded by even more degraded versions. There are four influential theories which explain this special effect： Erroneous Hypotheses Account, Competitive Activation Model, Mismatch Explanations and Feature Modulation Search Model. The determinants of the cue-depreciation effect found in empirical studies consists of starting point, viewing time, study style, strategies application, individual differences, unfilled interval, and presentation order. In the last part of this paper, the tendency of further research was proposed by presenting the strengthening on the research of foundmental theory, the precise applying of measure indices, the gradual raising of applied value and the exploitation of the unknown areas.
