摘要/Abstract

摘要： 根据反应抑制的独立和交互竞赛模型，在E-Prime 2.0软件平台上完成停止信号任务，提出一种新的跨通道停止信号任务用于检测被试者反应抑制的监测和调整。在此基础上，将设计好的程序对一组小学生被试者和一组大学生被试者进行实测，结果提示随着年龄的增加，反应被试者抑制能力的停止信号反应时间逐渐缩短，体现了抑制能力在儿童时期到青少年期逐步增强的发展规律。研究证明了设计程序的正确性和可靠性，并可为进一步的临床应用提供技术支持。

Abstract: A visual-auditory cross-model stop signal task is designed to test monitoring and adjustment of response inhibition based on the independent and interactive race models using E-Prime 2.0 software，one group of students from elementary school and anther from university participated in the task.The Stop Signal Reaction Time（SSRT） decreases with the age grow，which indicates the inhibition ability improves from childhood to adolescent period.The experimental results suggest that this program is correct and reliable and can provide technique support for further clinical application.

Key words: response inhibition, stop signal task, stop signal reaction time, E-Prime
