【摘要】：激活狀態(tài)是對即將發(fā)生的行為做反應(yīng)的準備情況,被試自身的激活狀態(tài)會影響其反應(yīng)表現(xiàn)。有研究認為根據(jù)任務(wù)和條件調(diào)整自身行為狀態(tài)的能力即狀態(tài)調(diào)節(jié)能力有缺損才是ADHD的關(guān)鍵問題,抑制缺損只是一種較低級的缺陷。作為一種更高一級的缺陷,狀態(tài)調(diào)節(jié)能力會影響反應(yīng)表現(xiàn)。本研究主要探討ADHD兒童的狀態(tài)調(diào)節(jié)能力對其反應(yīng)執(zhí)行和反應(yīng)抑制的影響,以及ADHD兒童是否存在狀態(tài)調(diào)節(jié)、反應(yīng)執(zhí)行、反應(yīng)抑制的缺損。 本研究所有的實驗通過刺激呈現(xiàn)速度影響被試的激活狀態(tài),不同激活狀態(tài)下的反應(yīng)差異體現(xiàn)狀態(tài)調(diào)節(jié)能力。通過設(shè)置時間隔控制刺激呈現(xiàn)速度,時間間隔為1秒的快速呈現(xiàn)速度引發(fā)被試過度激活的狀態(tài),時間間隔為4秒的中等呈現(xiàn)速度引發(fā)正常的激活狀態(tài)。實驗一要求被試完成在兩種刺激呈現(xiàn)速度(快速、中速)下朝向眼跳與反向眼跳組合的眼跳任務(wù),通過潛伏期、眼跳方向錯誤率分別考察被試的反應(yīng)執(zhí)行能力、反應(yīng)抑制能力。實驗二在實驗一的基礎(chǔ)上添加了線索以控制注意,考察控制注意后狀態(tài)調(diào)節(jié)能力對反應(yīng)執(zhí)行和反應(yīng)抑制的影響模式是否發(fā)生變化。實驗二采用Posner的空間啟動范式,分別從內(nèi)源、外源線索兩種線索考察狀態(tài)調(diào)節(jié)能力對反應(yīng)的影響模式。實驗二通過潛伏期、預(yù)期眼跳率分別考察反應(yīng)執(zhí)行能力、反應(yīng)抑制能力。 研究的主要結(jié)論是：(1)與正常兒童相比,ADHD兒童存在反應(yīng)抑制能力缺損,反應(yīng)執(zhí)行能力無損傷,與正常兒童基本一樣。(2)與正常兒童相比,ADHD兒童的反應(yīng)執(zhí)行能力不易受狀態(tài)調(diào)節(jié)能力影響,加入無效內(nèi)源線索后改變了影響模式,即狀態(tài)調(diào)節(jié)能力對其產(chǎn)生了影響；ADHD兒童的反應(yīng)抑制能力易受狀態(tài)調(diào)節(jié)能力影響,加入提示線索(有效、無效)后改變了影響模式,即狀態(tài)調(diào)節(jié)能力對反應(yīng)抑制能力的影響不顯著。(3)內(nèi)源和外源兩種線索對狀態(tài)調(diào)節(jié)和反應(yīng)執(zhí)行的影響模式不同,加入內(nèi)源線索后改變了狀態(tài)調(diào)節(jié)對反應(yīng)執(zhí)行的影響模式,而加入外源線索后影響模式?jīng)]變化。(4)與證常兒童相比,ADHD兒童的狀態(tài)調(diào)節(jié)能力有缺損。
[Abstract]:The activation state is the readiness to respond to an impending behavior, Some studies suggest that the ability to adjust their behavioral state according to tasks and conditions, that is, the defective ability of state regulation, is the key problem of ADHD. Inhibition of defect is only a lower level defect. As a higher level defect, the ability of state regulation will affect the response performance. This study mainly studied the effect of state regulation ability of ADHD children on their response execution and response inhibition. And whether there is a defect of state regulation, response execution, and response inhibition in ADHD children. In some experiments, the activation state of the subjects was affected by the rate of stimulus presentation, and the response differences in different activation states reflected the ability of state regulation, and the speed of the stimulation was controlled by setting time intervals. A fast rendering rate with a time interval of 1 second leads to a state of over-activation, while a moderate rendering speed of 4 seconds leads to a normal state of activation. Under moderate speed), the task of saccade in combination with reverse saccade was used to investigate the ability of reaction execution and inhibition of reaction through incubation period and error rate of direction of saccade. Experiment 2 added clues to control attention on the basis of experiment 1. To investigate whether the mode of influence of state regulation ability after control attention on reaction execution and response inhibition has changed. Experiment 2 adopts the spatial priming paradigm of Posner, which is derived from endogenous, respectively. Exogenous cues were used to investigate the effects of state regulation on response. In experiment 2, the ability of execution and inhibition of response were examined by latent period and the expected rate of knuckles. The main conclusion of the study is: compared with the normal children, ADHD children have the ability of response inhibition, and the ability of response execution is not impaired. The response ability of ADHD children is not easily affected by the state regulation ability compared with the normal children. After adding invalid endogenous cues, the influence mode is changed. That is, the ability of state regulation had an effect on the response inhibition ability of ADHD children, and the response inhibition ability of ADHD children was easily affected by the ability of state regulation. After adding cues (effective and ineffective), the influence mode was changed. The effects of endogenous and exogenous cues on state regulation and response execution were different, and the influence mode of state regulation on response execution was changed after the addition of endogenous cues. However, the influence mode of ADHD was not changed after the addition of exogenous cues. 4) the ability of state regulation of ADHD children was impaired compared with that of normal children.
