Final answer:
Hearing voices ordering self-harm is classified as a hallucination, whereas believing in false personal persecution is a delusion.
The scenario likely indicates a psychological disorder where such experiences are symptoms rather than divine communications.
Therefore, the correct answer is: option "hallucination; delusion".
Step-by-step explanation:
A hallucination is a sensory experience of something that does not exist outside the mind, often audible or visual, and can occur in any sensory modality.
Conversely, a delusion is a firmly held false belief that is not consistent with the person's culture or subculture. Believing that you are being investigated and pursued when there is no factual basis to support this belief is a delusion.
In the context of the scenario provided, where a mother claims to have been ordered by God to harm her child, this could be indicative of a psychological disorder such as schizophrenia, where individuals often experience hallucinations or delusions.
It is generally accepted that such commands are not divine but symptoms of an underlying mental health issue. Most would likely agree that a divine being would not command an act of harm or violence, thus suggesting the need for psychological assessment and potential treatment for the individual.
