Keysar等把由于使用外语和母语而导致不同结果的现象概括为外语效应。大量研究表明,使用不同语言会深刻地影响个体的认知、情绪和生理状态。外语效应在道德判断领域已被表明是稳定存在的,且表现形式多样。目前的研究主要包括以Costa等为主的“控制加工假说”和以Geipel等为主的“自动加工假说”。未来研究有必要探索道德外语效应的核心心理机制,进一步界定道德外语效应的影响范围和存在方式。 Keysar et al. Summarize the phenomenon of different outcomes due to the use of foreign and native languages ​​as a foreign language effect. Numerous studies show that the use of different languages ​​will profoundly affect the individual’s cognitive, emotional and physiological status. Foreign language effects have been shown to be stable in the field of moral judgment, with diverse forms of presentation. The current research mainly includes “Control Machining Hypothesis” mainly based on Costa and “Automatic Machining Hypothesis” based on Geipel. It is necessary for future research to explore the core psychological mechanism of moral foreign language effect and to further define the scope and existence of moral foreign language effect.
