contents Psychological and Cardiovascular Effects of Guaraná and Yerba Mate: A Comparison with Coffee Katherine Meyer Peter Ball Psicología Coffee guaraná yerba mate performance An exploratory experiment was conducted to investigate the effects of coffee, guaraná, and yerba mate onmood and performance, and to determine any potential of these beverages to overcome the soporific effects oflunch. Seventy-one female students were assigned to four beverages, including a decaffeinated coffee control,and tested on two days (lunch/no lunch), over three sessions (prior to drinking the beverage, and again 60 and150 minutes after drinking the beverages). Lunch had little effect other than to increase pulse. Guaraná increasedsystolic blood pressure and accuracy on a vigilance task; coffee increased accuracy on the vigilance task; butyerba mate had no significant effects. Further research is recommended before any definitive conclusionsabout the effects of guaraná and yerba mate are reached. 2004 artículo científico 0034-9690 https://www.redalyc.org/articulo.oa?id=28438110 en http://www.redalyc.org/revista.oa?id=284 Revista Interamericana de Psicología/Interamerican Journal of Psychology application/pdf Sociedad Interamericana de Psicología Revista Interamericana de Psicología/Interamerican Journal of Psychology (Puerto Rico) Num.1 Vol.38
