摘要：During the Ramadan fasting, the life style of Muslims is changed by the physiological and the mental effects of fasting, which are associated to altering metabolic and circadian rhythm. The present experiment for the first time looked into the visual spatial attention affection by Ramadan fasting via behavioral and Event Related Potential (ERP) measuring for 26 participants to reveal the temporal and spatial brain activities; before-, during-, and after- fasting periods. Besides, two factors concerning hydration, and glucose level had been evaluated. The results provedthat hydrationrate were changed significantly during the Ramadan (p<0.05). Also, the findings illustrated that the Ramadan fasting biased the visual food attention, which were supported by P1andP3, as an ERP evidence and RT as a behavioral result through both automatically and involuntary mechanisms. However, the correlation between glucose rate and biased visual food attention declared the more effective rule of energy regulation system in the dot-probe paradigm. Nevertheless, the results revealed that the highly significant increase in visual food attention during Ramadan had been more related to food reward than energy regulation system
