The Role of Behavioral Activation/ Inhibition System and Morningness and Eveningness type with Student's Positive academic Emotions

The aim of the current research was to study the role of behavioral activation/ Inhibition system and morningness and eveningness type with student's positive emotion achievement. Its descriptive and correlational design and statistical population included all first-grade high school male students in Chaypareh City in 2019-2020. In the same light, 211 subjects were selected using the multi-stage cluster sampling method. The Pekrun's achievement emotions, the Carver and White's Behavioral activation/ Inhibition, and the Horne and Östberg's morningness and eveningness type inventories were used to gather the data. Multivariate regression revealed that behavioral activation/ inhibition system and morningness and eveningness type significantly predict positive achievement emotions. Biological factors seem to play a role in morningness and eveningness type and the regulation of behavioral inhibition and activation systems as well, the morningness types and behavioral activation systems play a role in positive achievement emotions.
