We examined the behavioral response (BR) and threshold (T) axes of Dunn's four-quadrant model of sensory processing (1997). We assessed whether they are ordinal ranges and if variation is associated with other similarly described characteristics: Introversion/Extraversion (I/E) of Eysenck's personality model (Sato, 2005), and somatosensory event related potentials (SERP) and their gating (Davies & Gavin, 2007). From healthy adults ( = 139), we obtained: Adult/Adolescent Profile (A/ASP, Brown & Dunn, 2002) and Eysenck's Personality Questionnaire, Brief Version (Sato, 2005) scores and peak amplitude and gating factor of SERP P50. We found that BR scores did not differ across normative categories of the A/ASP, but T scores significantly increased along the axis. I/E scores did not vary with BR scores. There were no differences or correlations in P50 amplitudes and gating with T scores. The findings suggest that the BR axis may not reflect a construct with ordinal range, but the T axis may. Dunn's concept of BR appears to be distinct from Eysenck's concept of I/E. SERP and its gating may not be directly reflective of sensory processing thresholds in healthy adults. Conclusions are limited by having few participants with passive behavior regulation or low threshold patterns of processing.
我们研究了邓恩（1997年）感觉加工四象限模型的行为反应（BR）轴和阈值（T）轴。我们评估了它们是否为有序范围，以及变化是否与其他类似描述的特征相关：艾森克人格模型（佐藤，2005年）的内向/外向（I/E），以及体感事件相关电位（SERP）及其闸门控制（戴维斯和加文，2007年）。从139名健康成年人中，我们获取了：成人/青少年概况（A/ASP，布朗和邓恩，2002年）以及艾森克人格问卷简版（佐藤，2005年）的得分，还有SERP P50的峰值幅度和闸门控制因子。我们发现，BR得分在A/ASP的不同标准类别间没有差异，但T得分沿轴显著增加。I/E得分与BR得分没有变化关系。P50幅度及闸门控制与T得分之间没有差异或相关性。研究结果表明，BR轴可能并不反映一个具有有序范围的结构，但T轴可能反映。邓恩的BR概念似乎与艾森克的I/E概念不同。SERP及其闸门控制可能并不直接反映健康成年人的感觉加工阈值。由于具有被动行为调节或低阈值加工模式的参与者较少，研究结论受到限制。
