Introducton: all cognitive processes somehow relate to brain states. Prospective memory, remembering cognitive ability to perform specific actions at some time in the future. Studies have shown that during the prospective memory tasks, the frontal, Coupled with frontoparietal networks, Anterior Cingulate Cortex, Posterior Cingulate Cortex, temporal cortex and insula are more activity in maintenance and understanding the intentions of prospective memory. The heart rate and heart rate variability during cognitive tasks can be predict qualitative differences in cognitive function between people. This study aims to assess neurocognitive and physiological in individuals with good and poor Prospective memory performance using computerized cognitive task and brain and heart frequency bands. Methods: In this study 68 students (22 with good Prospective memory performance and 29 with poor Prospective memory performance) were selected using call and screening method (computerized cognitive task TBPM) and were studied according to a causal- comparative method. computer cognitive task (TBPM) was used to evaluate prospective memory and Procomp2 -Thought Technology Ltd was employed for EEG recordings at Fz (10-20 International Placement System. Multivariate analysis of variance (MANOVA) was used for comparesons between groups. Results: The results showed significant difference between the two groups with good and poor Prospective memory performance scores in brain wave of Alph band) Low alpha Ep mean) (p<0.001), (Low alpha Ep mean (long)) (p<0.0009(, (Alpha Ep mean) (p<0.001),) Alpha Ep mean (long)) (p<0.0009), (Alpha mean) (p<0.001). and heart wave of (BVP IBI std. dev. (SDRR)) (p<0.01), (BVP VLF total power mean) (p<0.02). Conclusion: Results showed that brain waves in the alpha band and heart waves on the heart rate variability is higher in individuals with good prospective memory performance. In fact, heart rate variability during prospective memory cognitive task can be to ex
