Shelby is a very outgoing person who likes being around other people and socializing with them. According to the Big Five trait theory of personality, Shelby would be considered:

a. showing signs of her masculine archetypes in her collective unconscious.

b. high on the stable and enduring personality disposition known as extraversion.

c. conditioned through past reinforcements to be uncomfortable in social settings.

d. using defense mechanisms to protect herself from feelings of inferiority.

I think it is b.

I agree.

To determine the correct answer, let's break down the question and analyze the options given:

The question states that Shelby is an outgoing person who enjoys being around others and socializing with them.

The options given are:

a. showing signs of her masculine archetypes in her collective unconscious.
b. high on the stable and enduring personality disposition known as extraversion.
c. conditioned through past reinforcements to be uncomfortable in social settings.
d. using defense mechanisms to protect herself from feelings of inferiority.

Option a: "showing signs of her masculine archetypes in her collective unconscious" is not directly related to Shelby's behavior of being outgoing and social. This option suggests a different theoretical framework, namely Carl Jung's theory of archetypes, which is not specifically addressed in the question.

Option b: "high on the stable and enduring personality disposition known as extraversion" suggests that Shelby's behavior aligns with the trait of extraversion. This option refers to the Big Five trait theory, which categorizes personality into five broad traits, one of which is extraversion. Being outgoing and enjoying socializing are typical traits associated with extraversion.

Option c: "conditioned through past reinforcements to be uncomfortable in social settings" contradicts the information provided in the question. Shelby is described as an outgoing person who enjoys being around others, which means that she is comfortable in social settings. This option does not align with the information given.

Option d: "using defense mechanisms to protect herself from feelings of inferiority" does not relate to Shelby's outgoing and social personality traits. It refers to defense mechanisms, which are psychological processes used to cope with anxiety or protect oneself from perceived threats. This option does not explain Shelby's behavior as described in the question.

Based on the analysis, it is clear that the best answer is b. Shelby would be considered high on the stable and enduring personality disposition known as extraversion, according to the Big Five trait theory of personality.
