Unconsouse heart rate varriation suppression for time durration tests?

Posted by StevenW on 20 Feb 2013 at 23:32 GMT

I wonder to what extent an individual judges time duration by heart rate, and suppresses variations while performing.

When younger and athletic I could hear/feel my heart beats, and used that feedback to practice my bio-feedback. and beat rate control.

Dear Steven,

thanks for your post. This is an interesting idea, although I would say that the cognitive tasks, even the easiest one were quite demanding to allow participants to concentrate in their heart beats and to use that as feedback. Moreover, if that was the case they would have been in a sort of dual-task mode, i.e., responding to the stimulus and concentrating in their HR. Then, we could have observed slower RTs in the high-fit group than in the low-fit group (we showed the reverse). In any case, this is an interesting issue that we will consider in our next experiments.
