Schizophrenia causes cognitive problems including impaired attention, processing speed, working memory, language, reasoning, and social cognition. Apart from having a difficult time recognizing emotions in other people and responding appropriately, individuals with schizophrenia also have trouble processing humor. Humor is used to facilitate social bonds and increase morale through social cognition. When someone is not able to understand humor, opportunities to forge social bonds with others and experience increased morale are lost.
