This study examined the connection\nbetween HRV and cardiac timing to learning.\nParticipants took part in single cue trace eye-blink conditioning. The stimuli were timed to the systolic or the diastolic phase of the cardiac cycle. HRV and EEG were recorded for the period of the task and for five minutes before and after. Six HRV variables were analysed: mean RR interval (MRR), root mean square of the successive differences (RMSSD), high frequency absolute power (HFA), low frequency absolute power (LFA), high frequency peak (HF peak), low frequency peak (HF peak) and high frequency/low frequency ratio (HF/LF ratio). Event related potentials (ERPs) were compared between the cardiac time groups and between good and poor learners.\nResults showed that the change of the MRR differed between good and poor learners. The MRR grew in good learners and declined in poor learners. The LFA increased and the LF peak was bigger in poor learners. There were no differences in learning between the systolic and diastolic groups, but N1 amplitudes were significantly bigger within the systolic group compared to the diastolic group.\nThe results imply that poor learners were more likely to lose interest in the task. Bigger N1 amplitudes in the systolic group could suggest that while on the sensory processing level there were\ndifferences, there are too many contributing factors to learning for the cardiac timing to affect it on a behavioural level. Further studies should be done to explore if learning is affected by HRV and/or cardiac timing in more complicated learning tasks.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Hanna Halkola (hakahalk) on 2018-02-05 09:52:01.680129.
