The word "reflex" can be described as an involuntary or automatic response to a stimulus. Antonyms for this word would include deliberate, intentional, or conscious actions. When making deliberate actions, we take time to think before making a decision or response, which is opposed to reflexes that occur without our conscious control. Antonyms for "reflex" can include voluntary, planned, or purposeful. For example, instead of having a reflex reaction to a loud noise, a person may choose to respond purposefully by covering their ears or investigating the source of the noise. Refining the ability to consciously act rather than relying on reflexes is an important skill for personal growth and development.
