Abstract Researchers have concentrated on studying the relationship between the factors that affect human behavior. The different human behavior and abilities have effect in the management of organizations and learning institutions. This study provides a differential approach in examining the factors that contribute to different human behavior and ability. Data pertaining to different individual measures were obtained for some 182 Organizational Behavior students. Measures on emotional intelligence, self-efficacy, and perceived stress were obtained using different instruments. A correlation analysis showed positive correlation between emotional intelligence and self-efficacy. A negative correlation was observed between perceived stress and emotional intelligence. A Similar correlation was observed between perceived stress and self-efficacy. The results illustrate the necessity of understanding emotions in managing perceived stress in different Introduction Individuals show different abilities to perform the tasks given to them in different settings like schools and places of work. Students in the learning institutions show different academic performances. Similarly, employees of an organization have different performance abilities for given tasks. Several factors may contribute to the different abilities of individuals. One such factor is self-efficacy. This may refer to the level of confidence that an individual have in his or her ability to perform a particular task and to execute a particular behavior successfully (Bandura, 1997 cited in Schyns and Moldzio, n.d). This is a flexible personal quality with its roots in the social cognitive theory (Gundlach, Martinko & Douglas, 2003, 229). The emotional intelligence of an individual is another factor that may affect the performance of the individual in different tasks. Emotional intelligence is the individual’s ability to be aware of, and manage, his emotions and the emotions of the others with whom they interact (Jordan, Ashkanasy, & Hartel, 2002, p.5; Cote et al, 2006).). The other factor that may affect performance is the perceived stress in an individual. Stress can be described as ‘the result of an imbalance between the physical or psychological demands encountered and the response capability of the individual, in case failure to meet the demands has important implications for the individual’ McGrath (1979 cited in Panda 2008). It is important to examine if the factors that affect the performance of an individual have a relationship with each other. The relationships that are observed are essential in the management of individuals with different abilities in diverse settings. Some researches have been conducted to study a relationship between these factors. Rathi and Rastogi (2008) carried out a research to investigate the relationship between self- efficacy and emotional intelligence. Another research was carried out by Panda (2008) to investigate the relationship between emotional intelligence and perceived stress. This research is based on the two previous researches and is intended to study the relationship between self-efficacy and perceived stress. The results of the researches indic
