امواج قلبی و عملکرد حافظه آینده‌نگر زمان‌محور دانشجویان دانشگاه کردستان در سال 95-1394

Background and Objective: Prospective memory performance is vital in everyday life. And considering the relationship between cognitive activity and cardiac parameters, this study aimed to evaluate heart waves and the time-based prospective memory performance and was conducted among university students of Kurdistan in 2015-2016. Materials and Methods: This study was a descriptive study that its statistical population included all university students of Kurdistan in the 2015-2016 school year. To obtain a prototype, at first a number of university students of Kurdistan through convenience sampling and calling were given some necessary information in relation to attending the research and reseach purposes andconduction method; among them 70 students who wish to participate in the study were evaluated. According to the study, after analysis of the results, results of 50 students (22 with strong time-based prospective memory performance and 28 with poor time-based prospective memory performance) were selected and studied. Time-based prospective memory computer tools and ProComp 2 Biofeedback System device to record the heart waves were used. The obtained data was analyzed using multivariate analysis of variance. Results: The results showed significant differences between the two groups with strong and poor time-based prospective memory scores in heart waves in the band (BVP IBI std. Dev. (SDRR)) that in fact, measures heart rate variability at the level of (p<0.05) This means that individuals with strong time-based prospective memory have a higher heart rate variability than those with poor time-based prospective memory. Conclusion: These findings show that attention to the results of heart rate variability during cognitive tasks can possibly show qualitative differences in cognitive function between individuals. So the results indicate a two-way communication between heart and brain function.
