The idea of how social interaction anxiety is related to language competence, fear of negative evaluation, and personality has led to the following research questions. 1. How are formal perceived competence, casual perceived competence, and Fear of Negative Evaluation correlated? 2. Do personality factors and FNE predict SIA? We predict the effects of the personality factors as follows: openness to new experiences will have a positive correlation with formal perceived competence and casual perceived competence but a negative correlation with FNE. Neuroticism will have a negative correlation with casual perceived competence, no correlation with formal perceived competence and a positive correlation with FNE. Extraversion will have a negative correlation with FNE and a positive correlation with casual perceived competence, but no correlation with formal perceived competence. Agreeableness will have a negative correlation with FNE but a positive correlation with formal and casual perceived competence. Conscientiousness will not have any correlations with FNE, formal perceived competence, or casual perceived competence.
