Introception detects sensations from which source?

• A. Internal organs
• B. External light
• C. External sounds
• D. Skin temperature only

Answer: (A)

Interoception is about sensing signals from inside the body, especially from visceral organs, such as the heart, stomach, and lungs. It covers sensations like fullness, hunger, and internal discomfort, rather than what comes from the outside world. External light and external sounds are detected by senses that gather information from outside the body (vision and hearing), so they fall under exteroception. Skin temperature is a somatosensory cue from the skin, not the internal organs, so it isn’t the primary source described by interoception. Therefore, the sensation source described by interoception is the internal organs.
