触觉防御（TD）的特征是对触觉刺激做出反应，如摩擦、抓伤、消极表达、退缩或回避等行为。文献中暗示了抑制缺陷，这也是本研究的重点。首先使用三种措施评估患有发育障碍的学龄儿童的 TD 水平。随后，孩子们在玩电脑游戏时受到重复的触觉刺激。每次试验都会记录反应的强度、持续时间和潜伏期。据推测，较高水平的 TD 与 (a) 较高的反应能力和 (b) 对触觉刺激的较慢的适应率有关。使用三个单独的 TD 测量值和一系列 3 x 10（试验中响应性的 TD 水平）重复测量方差分析的相关性来检验这两个假设。在一些初步测量中表现出较高水平 TD 的儿童在实验情况下也表现出较高的反应能力。不存在一般的习惯效应，并且有限的试验组相互作用无法解释。我们的结论是，有证据表明 TD 存在差异敏感性，但没有抑制缺陷。另一个重要发现包括 TD 与发育年龄之间的负相关。
Tactile defensiveness (TD) is characterized by behaviors such as rubbing, scratching, negative expressions, withdrawal, or avoidance in response to tactile stimulation. An inhibition deficit has been implied in the literature and is the focus of this study. School-aged children with developmental disabilities were first assessed for level of TD using three measures. Later, the children were presented with a repeated tactile stimulus while engaged in a computer game. Intensity, duration, and latency of the responses were recorded on each trial. It was hypothesized that higher levels of TD would be associated with (a) greater responsiveness and (b) slower habituation rates to the tactile stimulus. Correlations of three separate TD measures and a series of 3 x 10 (Level of TD by Responsiveness across trials) repeated measures ANOVAs were used to test the two hypotheses. Children who demonstrated higher levels of TD on some of the preliminary measures also showed higher responsiveness in the experimental situation. There was no general habituation effect, and the limited group by trials interactions were not interpretable. We concluded that there is evidence for a differential sensitivity in TD, but not an inhibition deficit. Another significant finding included a negative correlation between TD and developmental age.
