Read the following Case-Study and answer the question that follow.

Vijay graduated from college and got a job at a local grocery store. After working for six months he began to hear voices of people hatching a plan to poison him. He stopped eating and drinking anything in the shop as he felt it tasted bitter and looked green in colour. He reported smelling strange odour in the shop, He would take long winding detours on his way home as he felt people were following him. He told his family that the supervisor was against him and would one day burn down the shop in an attempt to kill him. One day he slapped a customer and swore that someone else made him slap him using his hand. No evidence was found to support his allegations.

Identify the hallucination that Vijay is NOT suffering from:

Tactile

The correct answer is Option (3) → Tactile 

Vijay is experiencing:

• Auditory hallucination (hearing voices plotting to poison him),

• Visual hallucination (seeing food as green in colour),

• Gustatory hallucination (believing food tastes bitter),

• and Olfactory hallucination (smelling strange odours).

There is no mention of tactile hallucination (false perception of touch or bodily sensations), hence it is the one he is not suffering from.

• Auditory Hallucination: This involves hearing things that aren't there, such as voices. Vijay hears voices of people hatching a plan to poison him, which indicates he is experiencing auditory hallucinations.
• Visual Hallucination: This involves seeing things that aren't real. Vijay reports that the food and drink in the shop "looked green in colour," which suggests he is perceiving something visually that isn't accurate, indicating a visual hallucination.
• Tactile Hallucination: This involves feeling sensations on the skin or body that aren't real, such as feeling bugs crawling on you. Vijay does not report any such sensations, like feeling touched, burned, or any physical sensation that isn't real. His act of slapping a customer and claiming someone else made him do it seems more related to a delusion of control rather than a tactile hallucination (where he would feel something physical).
• Gustatory Hallucination: This involves tasting things that aren't real. Vijay mentions that the food and drink "tasted bitter," which suggests he is experiencing a gustatory hallucination, as this perception of taste is likely not based on reality (since he also stopped eating and drinking due to his suspicions).
