All of the choices represent manifestations of disorganized thoughts in the speech associated with a paranoid schizophrenia. This described as "disorganized speech" and represents a symptom that is characteristic of paranoid schizophrenia. "Tangentiality" is steering away from the topic at hand. For instance: 

Q: Have you been nervous or tense lately?

A: No, I got a head of lettuce.

"Derailment" occurs when the topic is constantly being changed. If asked whether or not they like TV, then a paranoid schizophrenic might respond with "My sister likes TV. I dance to what's on the TV. I like to draw and read stories." The patient can also cleverly coin new terms on the spot, which are called "neologisms." Last, excessive rhyming or almost poetic-like speech is calling "clanging." 

All of the answer choices represent cognitive symptoms commonly associated with paranoid schizophrenia (i.e. symptoms regarding thinking, focus, and memory). Negative cognitive symptoms include a lack of concentration, memory, and an inability to express one's thoughts. On the other hand, positive cognitive symptoms include disorganized thinking that is generally chaotic and irrational.

Positive symptoms are defined as behaviors or patterns that are "added" to an individual possessing a mental disorder as opposed to symptoms that are taken away. "Affective flattening," "avolition," and "alogia" are all defined by the absence of certain aspects of cognition that a non-affected person would possess. On the other hand, "hallucinations," that is distortions in perception of what is real, are a positive symptom of paranoid schizophrenia.

Alogia can be one of the symptoms that paranoid schizophrenic experiences. It is a negative symptom characterized by a lack of language production as a result of "blocked thought." This is often manifested in short, empty phrases.

Delusions are firmly held erroneous beliefs that are a product of distortions or exaggerations of reasoning and/or misinterpretations of perceptions or experiences. When someone has paranoid schizophrenia, delusions of being followed or watched are common; furthermore, those suffering from this disorder may believe that radio or TV programs are sending them special messages. This is paranoid thinking, which is the identifying pattern of the illness. It creates a world for the affected person where everyone is "out to get them."

Clanging is a positive symptom of schizophrenia where the affected person will rhyme words despite the resulting utterance meaning nothing. For instance, although "I had my lunch when it's brunch it makes a crunch in a bunch" may convey meaning it will often not mean anything in context. The other answers are examples of a neologism, tangentiality, and an unrelated speech production error common among non-affected people (e.g. "I don't bike lats").

All of the answer choices are kinds of delusions that a paranoid schizophrenic typically experiences. "Paranoid delusions" are "beliefs of persecution" typified by a conception of the world as a place where everyone is out to get you. "Delusions of grandeur" involve beliefs that you possess special powers such as the ability to see the future. "Somatic delusions" involve false beliefs about abnormalities in the individual's body. Last, "delusions of reference" involve beliefs that things in your environment are directly related to you somehow, like believing someone built a random building for you.

All of these are kinds of hallucinations a paranoid schizophrenic may experience, an additional one being gustatory hallucinations (i.e. tasting things that aren't there). "Visual," "auditory," "tactile," and "olfactory" hallucinations are when one believes they are seeing, hearing, touching, and smelling things that are not there. Hallucinations are disturbing experiences that perpetuates the paranoid schizophrenic's sense of fear.

Schizophrenia is a severe mental disorder that can be passed down genetically though is more often inherited by men. Symptoms are often seen in adolescence to early adulthood and are sometimes triggered by environmental stressors such as the death of a family member, physical illness or other trauma. Much research has been done on the disease and the exact causes and origins are largely unknown though nature and nurture play a huge role.
