摘要
口音、口味和身份认同三件伴随终身的大事表面上看似毫无关联,实则有着深刻的内在联系.它们都是在童年这个关键期初步形成、逐渐发展并趋于稳定,而且其时间进程和发展规律基本一致.三者一致的关键期效应并非仅源自感性认识和生活经验,更非偶然巧合,而是直接关联人类大脑和肠道菌群发育过程的生理基础.这一观点在一项针对当代青年的问卷调查中得到有力确认.据此,深刻理解并充分用好语言习得、口味形成和情感身份认同的内在联系及关键期效应,有助于从孩童时期起建立个体对家乡故园和国家民族稳定恒久的情感认同和心理归属.
Abstract
Accent,taste,identity are three lifelong matters that may initially appear disparate.However,a closer examination reveals their profound interconnections.They are all formed,developed,and stabilized during the critical period of childhood,demonstrating remarkable synchronicity in their development timelines and patterns.This consistent critical period effect among the three transcends perceptual knowledge and life experience,nor is it a mere coincidence.Instead,it is directly related to the biological foundations of human brain and gut microbiota development.We then conducted a questionnaire survey among the contemporary youth,yielding compelling evidence in support of this view.This paper highlights the pivotal role of childhood as the critical period.By fully utilizing the critical period effect,we can foster bilingual or multilingual language acquisition,cultivate a diverse taste and food preferences,and nurture a stable and enduring emotional connection and sense of belonging to one's hometown and motherland.
