| 摘 要： | 采用"预警提示-目标探测"范式,对视觉刺激探测的警觉性注意特征进行初步探索。实验一表明,随着预备到目标刺激的时间间隔(interstimulus interval,ISI)变化,固定位置上探测目标刺激的速度也随之变化,并且对大概率刺激的探测更快,表现出了警觉性注意的稳定性和选择性特征。实验二进一步考察了目标刺激在不同ISI和不同空间位置的情况,除发现与实验一相似的结果以外,被试探测目标刺激的速度随注意视角增大而下降,表现出了警觉性注意的集中性特征。 |

| Abstract: | Using "warning-target detection" paradigm,this study explored the attributes of vigilant attention in visual detecting task.The results of experiment 1 showed that the reaction times on distinguishing the stimulus that has a fixed position vary with the change of interstimulus interval(ISI)between ’ready’ and ’target’,and were shorter for probability stimulus,as a reflection of selectivity and stability of vigilant attention.Experiment 2 examined the factor of spatial locations in visual detecting task,and a similar phenomenon was observed as experiment 1.Moreover,the RTs on detecting a stimulus in unfixed position decreased significantly with the increase of visual angle,most likely was related to the concentrativeness of vigilant attention. |
| Keywords: | vigilant attention stability selectivity concentricity |
