Expectation predicts performance in the mental heartbeat tracking task

The mental heartbeat tracking task by Schandry is sensitive to non-interoceptive (top-down) influences, e.g., estimation of heart rate and expectation. two studies reported here investigated the impact these factors on outcome task. In Study 1, performance-related expectation was assessed between training interval real trials. Performance strongly related (? = .595, p < .001) even after controlling for sex, body fat, resting rate. 2, before Group 1 respectively. strong association (r 0.78, performance replicated 2; however, a moderate 0.39, .01) also found in 1. People with high may be prone categorize count vague sensations, such as attention evoked heartbeats; this can lead an inflated Schandry-score.
