幻觉振动触觉运动可用于在皮肤上提供定向触觉信息。我们的研究问题是演示方法如何影响振动触觉运动的感知。左前臂背侧引发振动触觉内侧运动的错觉，以研究振动触觉刺激的认知和情感体验。十八名参与者接受了传递到线性排列的三个振动触觉执行器的刺激。使用三种呈现方法——跳跃、幅度调制和混合方法——形成 12 种不同的运动模式。首先，使用两种选择的强制选择程序（相同或不同的判断）对刺激进行两两比较。其次，使用三个九点双极量表对刺激进行评级，测量每个刺激的连续性、愉悦性和唤醒度。使用调幅方法呈现的刺激明显更连续、更令人愉悦，并且较少引起兴奋。研究发现，与认知相关的连续性量表与与情绪相关的愉悦感和兴奋度量表之间存在很强的相关性：连续性刺激越多，人们就越感到愉快，而唤起性越低。
Illusory vibrotactile movement can be used to provide directional tactile information on the skin. Our research question was how the presentation method affects the perception of vibrotactile movement. Illusion of vibrotactile mediolateral movement was elicited to a left dorsal forearm to investigate cognitive and emotional experiences to vibrotactile stimulation. Eighteen participants were presented with stimuli delivered to a linearly aligned row of three vibrotactile actuators. Three presentation methods were used--saltation, amplitude modulation, and a hybrid method--to form 12 distinct patterns of movement. First, the stimuli were compared pairwise using a two-alternative forced-choice procedure (same-different judgments). Second, the stimuli were rated using three nine-point bipolar scales measuring the continuity, pleasantness, and arousal of each stimulus. The stimuli presented with the amplitude modulation method were rated significantly more continuous and pleasant, and less arousing. Strong correlations between the cognition-related scale of continuity and the emotion-related scales of pleasantness and arousal were found: More continuous stimuli were rated more pleasant and less arousing.
