摘要
采用结构方程模型的方法探讨中央执行系统与时距加工过程的关系,考察三种中央执行子功能(转换,抑制,刷新)对预期式长、短时距估计(两种标准时距:2s,5s)的作用模式。结果发现刷新功能对长、短时距估计任务都产生影响;抑制功能只作用于长时距估计;转换功能不参与单独的预期式时距估计过程。结果表明,三种执行子功能对预期式短时距加工和长时距加工的作用不同,支持时距加工的差异机制假设。
Time is a fundamental property of matter. Duration judgment is of great significance for human beings to survive and adapt to environments. Extended resource allocation model of duration judgment considers that duration judgment primarily depends on attentional and working memory resources. The demonstration bidirectional interference effect between duration judgment and non-temporal task that associated with executive processes in dual-task paradigm of time and non-time provide support for that duration judgment is affected by central executive function. Miyake et al. （2002） identified three relatively independent sub-functions of central executive function, which they termed “switching”, “inhibition” and “updating”. Switching involves shifting attention back and forth between multiple tasks or cognitive operations. Inhibition is a basic executive control process that includes suppressing dominant, automatic responses and resisting distractions. Updating refers to updating information in working memory contents by people as needed. When appropriate, information that is no longer current or relevant is replaced with newer information. Researches abroad on the relationship between duration judgment and central executive function show that the effects of different central executive sub-functions on duration judgment are not the same. Previous researches were limited for deciding which of two models better describes the empirical data. Therefore, we established structural equation modeling as a methodological approach to test the relationship between different executive sub-functions and duration judgment, the extent of the impact of executive sub-functions on duration judgment, and further investigate the validity of the common timing and the distinct timing hypotheses. The experiment of this study included three executive function tasks and two different lengths of perspective duration judgment tasks. The three executive tasks which represented shifting function （Local-Global task）, inhibition
