Step-by-step explanation:
In terms of schizophrenia, positive symptoms include delusions and hallucinations, while negative symptoms include a flattened emotional state and loss of pleasure. Delusions are false beliefs that are not based in reality, while hallucinations are sensory experiences that are not actually happening. On the other hand, negative symptoms refer to the absence or reduction of normal behaviors, such as a lack of emotional expressiveness and a decreased ability to experience pleasure.
