五名成年人在肿块检测任务中触诊硅胶乳房模型。在三个阶段中，使用离散试验（限制搜索程序）和“自由反应”（自由搜索程序）的心理物理学方法的检测几个肿块和模型特征的影响进行了研究。在第1阶段，固定钢块的尺寸和深度不同。在第二阶段，尺寸均匀、固定的团块的深度和硬度有所不同。还在第1和第2阶段研究了模拟乳腺结节的存在和深度。在第3阶段，所有乳房模型均为均匀结节状，肿块的大小、深度、硬度和固定度沿着尺寸变化。在第1阶段，肿块检出率最高，模型内肿块尺寸最大，深度最小。在第2阶段，肿块硬度和深度均不会对固定肿块的检测产生差异性影响。当乳房肿块是移动的时，在第3阶段，大小和硬度是决定检测的主要刺激尺寸。这些结果建议用于训练有效的乳房自我检查和乳房肿块检测的真实乳房模型和肿块的物理参数。
Five adult humans palpated silicone breast models in a lump-detection task. The effects on detection of several lump and model characteristics were studied in three phases, using both discrete trial (restricted search procedure) and “free response” (free search procedure) psychophysical methods. Size and depth of fixed steel lumps were varied in Phase 1. Depth and hardness of uniformly sized, fixed lumps were varied in Phase 2. The presence and depth of simulated breast nodularity were also studied in Phases 1 and 2. In Phase 3, all breast models were uniformly nodular and lumps varied along dimensions of size, depth, hardness, and fixation. In Phase 1, lump detection was greatest with maximum lump size and minimum depth within the model. Neither lump hardness nor depth differentially influenced detection of the fixed lumps in Phase 2. When breast lumps were mobile, in Phase 3, size and hardness were major stimulus dimensions determining detection. These results suggest physical parameters for realistic breast models and lumps to be used in training effective breast self-examination and breast lump detection.
