儿童的检测时与智力

采用三种视觉检测时任务，考察了儿童的检测时的特点以及儿童的检测时与智力之间的关系。结果发现：随着年龄的增长，儿童的检测时有逐步减小的趋势；儿童的检测时依赖于加工任务的类型。儿童的检测时与智力测验分数之间具有中等程度的负相关，并且两者之间的相关程度受加工任务和年龄因素的影响；与检测时快的儿童组相比，检测时慢组的检测时能够更好预测其智力测验分数。

THE RELATIONS BETWEEN INSPECTION TIME AND INTELLIGENCE OF CHILDREN

Studied the relationship between intelligence test performance and 3 visual inspection time measures including classical line inspection time, digital inspection time and component of Chinese character inspection time. 84 children, including 7 year olds, 9 year olds and 11 year olds, attended the test for 3 kinds of inspection time, all subjects also completed the Cattell's culture free test. Results indicated that inspection time in various tasks all showed trends of decreasing with increasing of ages. However, there were different speed of processing and change of development in the different tasks: the digital inspection time was longest in all tasks and the component of Chinese character inspection time was the shortest. From 7 year olds to 11 year olds, the line inspection time decreased slowly, while digital inspection time decreased quickly. No differences had been found between the sexes in different inspection time tasks. Experiments had showed that although inspection time of children is moderately correlated with intelligence test scores, the strength of the correlation between inspection time of children and intelligence test scores is attenuated relatively after controlling age factor. Correlation between inspection time of children and intelligence test scores is influenced by different inspection time tasks: digital inspection time task is sensitive to age variance, while line inspection time task is sensitive to within-group variance. Experiments also displayed correlation between faster inspection time groups, slower inspection time groups and intelligence test scores. Results showed that slower inspection time of children was significantly correlated with intelligence test scores, while faster inspection time of children and intelligence test scores were unrelated after controlling age factor.This finding suggested that worst performance (i.e., slower inspection time ) was a better predictor of IQ than best performance ( i.e. , faster inspection time).
