Our mind does not see, it perceives. Perception works by projecting meaning to define our experiences. Our body’s chemistry responds according to how we define what we perceive. We may perceive news of someone saving a baby from a burning building differently to news about someone who violently attacks a child. ‘Perceptually induced chemical responses’ can vary dramatically. Our definitions for what we feel when we perceive experience can include the terms ‘happy’, ‘enjoyment’, ‘bored’, ‘numb’, ‘uneasy’, ‘anxious’, ‘fear’ and ‘terrified’.
