Definition

Noun: * The process of perceiving or the faculty of perceiving stimuli that originate from outside the body. It is the sensory awareness of the external environment, as opposed to interoception (internal bodily sensations) or proprioception (body position).

Usage

Exteroception is a technical term used primarily in psychology, neuroscience, and physiology. It refers to the collective function of the senses that gather information about the world external to the organism. * The five classic senses—sight, hearing, touch, taste, and smell—are all modes of exteroception. * It is often discussed in contrast to other sensory systems like interoception.

Examples

• Noun:
  • Vision and hearing are the primary channels of human exteroception.
  • The study focused on how exteroception is integrated with proprioception to guide movement.
  • Damage to the sensory cortex can impair exteroception.

Advanced Usage

• Exteroceptive (adjective): Pertaining to exteroception.
  • Exteroceptive signals from the skin provide information about texture and temperature.
• The term is central to discussions of perception, distinguishing external sensory input from internal (interoceptive) states like hunger or heartbeat.

Variants and Related Words

• Exteroceptive (adj): Of or relating to exteroception.
• Exteroceptor (n): A sensory receptor, such as those in the eye, ear, or skin, that responds to external stimuli.

• Proprioception (n): The sense of the relative position of one's own body parts and strength of effort being employed in movement. (Contrast)

Synonyms

• External perception
• External sensibility
• (In specific contexts) Sensory perception (though this can include interoception)

Antonyms
