How emotions are processed affects people's cognition and behavior. One of the most used measures to study the physiological component of emotions is heart rate (HR), where greater HR variation (range) implies greater emotional processing. Several investigations established the importance of gender modulation of these processes due to the different cultural treatment given to emotions among genders. However, very heterogeneous results are reported today, and few studies incorporated these parameters when investigating emotion modulation of cognitive processes according to individual factors. The present work consists of two studies. In a pilot study, 97 young adults, through the Self-Assessment Manikin (SAM), ranged the valence and arousal to select two positive and neutral videos. The second study analyses the role of gender and valence in the variation of subjective (SAM) and physiological (HR) indicators of emotional processing associated with performance in two cognitive tasks (Stroop and Tower of London) under two different emotional conditions. Participants were 60 adults, who were randomly assigned to positive or neutral video visualization, and their HR was registered. There was a tendency for women to have higher HR during positive videos than in neutral. While the subjective reports indicated variances in the appraisal of the videos, the heart rate did not exhibit differences across the experimental conditions. Few studies integrate emotional and cognitive components, and include physiological and subjective measures of emotional processing. These findings illustrate the importance of including various measures of emotional and cognitive processing.
