Absence
Absence, when used in medicine or psychology, refers to a lack of presence of overt symptoms, skills, or traits. For instance, someone who is known to have the power of speech stops speaking. This absence of speech is a symptom that something is wrong. Another example would be the trait of psychopaths to have an absence of empathy for others.
