Final answer:
Emotional intelligence is the umbrella term that covers a specific set of traits that positively affect performance. It includes the ability to understand and manage emotions and is often considered a better predictor of success than traditional intelligence. Personality traits and various factors also significantly influence an individual's intelligence level.
Step-by-step explanation:
The umbrella term covering a specific set of traits that positively affect performance is emotional intelligence. Emotional intelligence encompasses the ability to understand one's own emotions and the emotions of others, demonstrate empathy, understand social relationships and cues, and regulate your own emotions to respond in culturally appropriate ways. High emotional intelligence typically correlates with well-developed social skills and has been suggested by some researchers, such as Daniel Goleman, to be a better predictor of success than traditional intelligence.
Personality traits are also connected to how individuals consistently think, feel, and behave, with Raymond Cattell identifying 16 personality factors, and other research focusing on the Big Five personality traits. While intelligence certainly plays a role in performance, it is also clear that personality and emotional intelligence have significant impacts. It's also important to recognize that many factors interact to influence an individual's intelligence level, including genetics and environmental influences. No single factor, such as poverty or family intelligence, determines an individual's full intellectual potential alone.
