Method of constant stimuli

An implementation of the method of constant stimuli of Brener, Liu and Ring [Brener et al., 1993] is planned for Cardioception. Tones are presented at several fixed delays spanning the cardiac cycle, commonly from R+0 to R+500 ms. Participants judge whether each was simultaneous with a heartbeat sensation.

A review of the literature will accompany the implementation. For an introduction, see A stronger measure of heartbeat timing.
