Three important types in the body: mechano-receptors (touch, pressure, vibration, movement) Yes, if sensations are pervasive and strong (e. g. extreme hunger, fatigue, pain) No, for weaker sensations; often ambiguous (e. g. correlation between perceived heart rate and actual heart rate is small (r = . 10); same for perceived vs. actual blood pressure and body temperature) Outdoor joggers pay less attention to their symptoms of fatigue.
