question 210

Essay

Steven is 24 years old and recently moved back in with his parents after two years of living on his own. He has begun to exhibit behaviors that concern his parents. He has become uncommunicative and ignores questions directed at him. He does not seem to care about things that used to interest him and has no appetite. Although most of the time he shows no emotion at all, Steven seems to take pleasure in watching the family cats fight, and he laughed when he overheard a conversation between his mother and a neighbor about the neighbor's miscarriage. Which of these behaviors may be symptoms of schizophrenia? Do Steven's behaviors indicate more positive or more negative symptoms?
