抽象。到目前为止，少数几项关于眼功能发展的研究表明，儿童和青少年时期的眼跳控制不同参数受年龄的影响。本研究的目的是确定一组22个参数的发展功能，来自检查的亲和反accades下引起的200毫秒的间隙和重叠的条件（100个试验下的四个条件）。统计分析（包括多元回归、协方差分析和主成分分析（PCA））基于199例6-28岁受试者的样本，包括66%的男性和34%的女性。主要结果如下：（1）在大多数情况下，变量“年龄-1”对因变量的预测效果优于年龄。(2)使用年龄和年龄-1作为预测因子的多元回归方法占标准方差的0-51%，这些值（调整后的R2）是大的方向错误的比例，在反突击任务（0.46-0.51），反（0.36-0.46）和前视（0.23-0.34）反应时（RT）及其标准差（0.26-0.45）居中，而快速扫视的比例可忽略不计。(3)年龄变量（特别是年龄-1），此外，预测的实验任务操纵的不同的因变量（例如，增加方向错误下的差距相比，重叠条件下的antiaccade任务）显着的一些影响。(4)主成分分析结果表明，在这个样本中的眼跳控制的5个因素：2个因素包括反眼跳参数，2个因素包括正面眼跳参数，和1个因素包括预期。最好的年龄变量与相应的因素得分的相关性，获得了2个因素相关的反跳任务参数。
Abstract. The few studies on the development of oculomotor functions conducted so far suggest strong developmental effects of age on different parameters of saccade control in childhood and adolescence. The present study aimed at determining developmental functions for a set of 22 parameters derivable from the examination of pro- and antisaccades elicited under the 200-ms gap and overlap conditions (100 trials under each of the four conditions). The statistical analyses (including multiple regression, analysis of covariance, and principal components analysis (PCA) were based on a sample of 199 subjects aged 6–28 years, including 66% males and 34% females. We obtained the following main results: (1) In most cases, the variable "age–1" predicted the dependent variables much better than age. (2) Multiple regression approaches using Age and Age–1 as predictors accounted for 0–51% of the criterion variances, these values (adjusted R2) being large for the proportion of direction errors during the antisaccade tasks (0.46–0.51), medium for anti- (0.36–0.46) and prosaccadic (0.23–0.34) reaction times (RT) and their standard deviations (0.26–0.45), and negligible for the proportion of express saccades. (3) The age variables (particularly Age–1), furthermore, predicted some of the effects of the experimental task manipulations on the different dependent variables (e.g. the augmentation of direction errors under the gap as compared to the overlap condition of the antisaccade task) significantly. (4) PCA results suggest 5 factors of saccade control in this sample: 2 factors comprising the antisaccade parameters, 2 factors comprising the prosaccade parameters, and 1 factor comprising the anticipations. The best correlations of the age variables with the corresponding factor scores were obtained for the 2 factors related to the antisaccade task parameters.
