Personal literature has been involving especially when the correlation between personality traits is the subject of the matter. Consistency in psychometrics of correlations between traits has been difficult given the fact that human beings are distinct and dynamic, and so do their characters. However, some predictive validity between different personality traits can be achieved to help in describing the general correlation of different characteristics.
Predictive validity is defined as the degree in which a score under one scale for a given trait predicts the outcome of the score when an unusual feature is investigated. Despite the underlying difference of the extraversion impact on the level of positive affect, there exists a relationship between extraversion and positive affectivity, whereby they both classify an individual as either an introvert or an extrovert, and biological concept in which the dopamine receptor impacts on positive affect and also the biological factor influence feeling of pleasure.
Extraversion
Extraversion and positive affect have been discussed and proven to correlate. According to
Srivastava, Angelo, and Vallereux (2008), extraversion is the behavior that is depicted by
individuals who are talkative, outgoing, and energetic. Nonetheless, it is with no doubt that every
person exhibit either extraverted or introverted behaviors. However, Jung (1995) reiterates that the
dominant behavior helps in classifying people as either extroverts or introverts. Therefore, the
concentration of interest and the general attitude of an individual towards external objects are
essential when carrying out such classifications. Based on the big five classifications of personal
traits, positive affect is often classified under extraversion, thus portraying a relationship
between the two aspects.
Positive Affect
Positive affect has a broad definition based on the individual interpretation of affective space.
Patterson, DeBarishe, and Ramsey (2017) describe positive affect as the pleasant condition induced
into a person by little things and events that happen daily throughout life. The link between
positive affect and extraversion can be cyclic given that their association can be counter
directional. Positive affect can be either low or high. However, extraversion is said to have less
influence on the level of positive affect of an individual. The underlying disparity on positive
affect among individuals is attached to the personal perception of pleasure. De Young (2013)
indicates that genetics play an important role in creating a disparity between high and low positive
affect valences. As Lucas and Baird (2004) support, this factor considers the genetic makeup of an
individual as playing a considerable role in influencing the manner and level of perception that an
individual has when exploring the environment. Therefore, the high and low positive affect valences
are not correlated to extraversion. However, the general pleasure that an individual feels is
motivated by the level of extraversion that person depicts.
Biological Concepts
The relationship between positive affect and extraversion goes beyond the environmental factors. In
this regard, the biological component of an individual has been found to influence the feeling of
pleasure. Studies have revealed that frequency and intensity of pleasure have been linked to
extrovert personality (Westen and Rosenthal, 2005). In addition, the dopamine receptor subtypes in
individuals influences the intensity of positive affect that different individuals experience. The
dopamine receptor has been scientifically proven to influence circuit activation which
consequentially influences intensity of positive affect. Hass et al. (2006) reinstate the fact that
genetic differences in individuals is responsible for divergence valence of positive affect
experienced by extroverts. On the other hand, neuroticism has been found to influence low positive
affect in response to negative stimuli.
Conclusion
Personal traits are very distinct and dynamic given that human beings are also different and potent.
Nonetheless, the predictive validity of an extrovert experiencing positive affect is high. This is
confirmed even though individuals do encounter varied valences of positive affect. Various studies
have confirmed that such disparities are associated with individual genetic makeup as well as
biological influences. In addition, the relation between extraversion and positive affect is cyclic
in nature, and thus sociability of an individual is the cord that links the two elements.
