******** is the decrease or cessation of all feelings of pleasure (which thus affects enjoyment, happiness, fun, interest, and satisfaction). Emotions relating to pleasure will not be expressed as much or at all because they are literally not experienced or are decreased. A person with ******* may be unable to laugh or smile, for example. Conversation will not be pleasurably stimulating for a person with extreme ******** , and thus that person may not be as responsive to conversation or its emotional subject matter.
