Abstract
The positive effects of interest on different aspects, e.g., learning and education, economy, psychological well-being, and social relations, have been widely addressed by many psychological and physiological studies in the last two decades. While the psychological work has investigated this impact of interest theoretically, the physiological studies have focused more on the modulatory effects. However, some studies have addressed both sides of the effects. In this work, we conduct a comprehensive review of physiological studies on interest detection, from different perspectives carried out between 2003 and 2019. A lack of connection between the psychological and physiological studies was identified. Therefore, this paper aims to integrate the unique psychological and physiological aspects and characteristics of interest to form a base for future research by considering the pros and cons of the included studies. For example, considering the two types of interest (situational and individual) the detected interest in learning, gaming, and advertisement’s physiological experiments could be referring specifically to situational interest. Hence, bridging the gap between both physiological and psychological studies is essential for improving the research on interest. Furthermore, we propose several suggestions for future work direction.

Summary
Definitions, hypotheses, and experiments regarding interest were proposed in the late 19th century. This work led to the proposal of a variety of definitions, and concepts, regarding interest. It is difficult to combine the conclusions of this research in one concept because of the uncontrolled settings of the experimental studies, or often, missing connections between the different fields of study. What could be so interesting about interest that grasped researchers’ attention and led to efforts to study and explore this area of research? Many researchers have proposed the idea of interest as a motivational variable and an important and basic element of productive learning. These researchers include Silvia [4], U. Interest has cognitive effects and physiological effects
