Final answer:
Cognitive symptoms of schizophrenia include decision-making problems, attentional problems, and memory problems. Manic episodes, while impacting mental functioning, are not characteristic of schizophrenia but rather bipolar disorder.
Step-by-step explanation:
Characteristic Cognitive Symptoms of Schizophrenia
Cognitive symptoms of schizophrenia can significantly impair a person's daily life and ability to function. These symptoms include: decision-making problems, which refers to difficulties in making choices and assessing the consequences of actions; attentional problems, which include an inability to focus or pay attention, leading to challenges in processing information and staying on task; and memory problems, which manifest as impairments in both short-term and long-term memory functions. It is important to note that while manic episodes might be associated with other conditions like bipolar disorder, they are not characteristic cognitive symptoms of schizophrenia.
