For me, I was reading &quot;fear response&quot; as physiological. A ball comes flying towards my face, my body releases adrenaline, my heart rate spikes, I tense or flinch. In that case I <i>also</i> experience the emotion of fear.<p>But sometimes the emotion is absent, see generalized anxiety disorder. I wasn&#x27;t <i>afraid</i>, but if you observed my heart rate, breathing, blood pressure two summers ago you would&#x27;ve thought I was having a constant panic attack. I wasn&#x27;t experiencing any fear (emotion), if anything it was confusion (I&#x27;d not experienced anxiety on that level in years so I wasn&#x27;t prepared for it again).
