To maximize the production and detection of training effects in biofeedback-assisted control of peripheral skin temperature, this study incorporated these methodological features: differential feedback between dominant and nondominant hands, monetary incentives, within-subjects manipulation of training direction and multiple-training sessions, graphic-based visual feedback, and no-feedback self-control periods. Eight male subjects participated in eight sessions each consisting of adaptation (22 min.), bidirectional self-control (10 min.), and bidirectional feedback training (35 min.). Mean differential temperature changes were significantly different for increase and decrease conditions, but the magnitude of control did not change over sessions. Differential feedback control was of small magnitude and tended to be accomplished by decreasing both hands at different rates; self-control did not develop during the course of training. This methodology did not produce large-magnitude feedback, or self-control, but differential feedback is recommended for further study as an experimental paradigm.
为了在生物反馈辅助控制外周皮肤温度中最大限度地产生和检测训练效果，本研究纳入了以下方法学特征：优势手和非优势手之间的差异反馈、金钱激励、训练方向的受试者内操作和多次训练、基于图形的视觉反馈以及无反馈自我控制期。八名男性受试者参加了八次实验，每次实验包括适应阶段（22分钟）、双向自我控制阶段（10分钟）和双向反馈训练阶段（35分钟）。平均温差变化在升温条件和降温条件下有显著差异，但控制幅度在各次实验中没有变化。差异反馈控制幅度较小，倾向于通过以不同速率降低双手温度来实现；在训练过程中没有形成自我控制。这种方法没有产生大幅度的反馈或自我控制，但差异反馈作为一种实验范式，建议进一步研究。
