检测时是信息加速度度的重要指标，检测时实验是当前智力研究领域中的一个重要范式。研究者试图通过检测时与智力之间的关系研究，探索人类智力的基础和智力个体差异的原因。关于检测时与智力之间的关系研究起源于70年代，但直到近几年，才真汇开始深入研究。日前，研究主要集中在探讨两者关系的实质上。研究对象基本上为正常成人。对儿童的检测时进行系统的研究还很少。本研究以7, 9, 11岁的城市小学儿童为研究对象，采用]检测时多任务作业方法。着重探讨了四个问题:(1)儿童检测叼的发展特点(2)儿童检测时与智力之间相关的普遍性;(3)从发展的角度，探讨检测时与智力之间的相关特点;(4)儿章检测时与认知能力之间的关系。研究结果如下:
Inspection time (IT) is an important key index of Speed of Information Processing (SIP) and IT experiment is an important paradigm in the domain of intelligence. Researchers try to explore the reasons of the differences between the basis of human's intelligence and individual's intelligence, through studying the relation between IT and intelligence. The study of the relation between IT and intelligence came from 70s, but the deeper study did not begin until recent years. At present the study focuses on discussing the essential of the relation between the two and the participators of these studies are usually normal adults. So there are few systematicly studies of IT which focus on the children. Thus this study focused on the children in urban whose ages are 7, 9 and 11 and used the methods of multitasks of IT to probe:
(1)The characteristics of the development of the children's IT. (2) The universalism of the relation between IT and intelligence of children. (3) exploring the characteristics of relation between IT and the intelligence of the children from the angle of development. (4) The relation between IT and the cognitive ability of the children.
From the present research, the following conclusions were drawn:
l.the characteristics of the children's IT represent as follows: firstly, with the increasing of the ages, IT has the trends of decreasing. Secondly, the speed of the development of the children's IT is influenced by the ages and the tasks of information processing. Thirdly, there are different speeds of the children's IT under different IT's tasks.
2. There is a significant correlation between IT and the scores of the intelligent tests of the children and the result has the universality. Seeing from the relations between IT and intelligence in different groups of ages, there is a moderately negative correlation between IT' and the scores of the intelligent tests of the children. With the increasing of the ages, the degree of the correlation between them has a certain fluctuation, which represents the trend of decreasing comparatively. It reflects that the increasing of experience and knowledge have effect on the relation between IT and the intelligent tests. Actually IT can reflect the liquid intelligence better.
3. There are different relations between IT and the intelligence to the children who have different levels of IT. Though there is obvious correlation between IT and intelligent tests to the children who are in both fast or slow IT groups, the groups which get slow IT can predict the scores of the intelligence better.
4. There is significant correlation between IT of children and the cognitive tasks which have the limitation of speed. It shows that the speed of center information processing has universal effect on the cognitive ability, which has the limitation of speed.
5. The basic units of IT's materials have a certain specialization to the cognitive ability. After controlling the factor of ages, the specialization has different representation on the different levels of cognitive tasks. In the general intelligent tasks it represents specialization, but in the factor of Gv there are no.
This study hinted that IT relate to two indiscerptible parts, which are the speed of central information processing and the basic units of materials. Thereinto, the speed of center information processing has universal effect on various cognitive activities and
