Final answer:
Abnormal facial expressions and poor eye contact may inadvertently lead to social misunderstandings, which can decrease rather than increase self-confidence. The facial feedback hypothesis also suggests that our expressions can influence our emotional state.
Step-by-step explanation:
Abnormal facial expressions and issues with eye contact and affect can lead to a variety of social and psychological consequences. These conditions have been shown to be reduced in individuals suffering from posttraumatic stress disorder (PTSD). Significantly, these facial expressions, or lack thereof, can also influence a person's emotional experiences. According to the facial feedback hypothesis, there is a reciprocal relationship between facial expressions and emotions. For instance, limiting expressions through Botox injections has been associated with reported decreases in symptoms of depression.
Moreover, abnormal facial expressions may lead to misunderstandings in social interactions, as they are key in conveying emotions and intentions. In terms of social implications, a person who avoids making eye contact might be perceived as lacking confidence or as unfriendly, which can potentially hinder the development of personal and professional relationships. Conversely, maintaining appropriate facial expressions and eye contact can help establish trust and rapport. Hence, rather than increasing self-confidence, issues with facial expressions and eye contact may inadvertently result in decreased self-esteem and potential isolation.
