Vagally mediated heart rate variability and safety learning: Effects of instructions and number of extinction trials.

abstract：:Sensitivity to heartbeat sensations is commonly assessed using tasks that require individuals to judge the simultaneity of heartbeats and tones. In two experiments, we investigated the suitability of this paradigm for examining cardioception. In the first experiment, participants judged the simultaneity of near-thresh...
