Tilting the head to one side, exposing the neck and softening the appearance.
Listening to a heartfelt account a person tilts the head gently toward the speaker. The small lean of the head softens the whole manner, signalling that the listener feels safe and engaged.
A tilt usually signals interest, empathy and a feeling of safety in the exchange. By exposing the neck it quietly shows a lack of threat, which tends to invite trust in return.
A prolonged tilt with a hard face can read as scepticism, so weigh the whole expression. The same tilt paired with narrowed eyes signals doubt rather than warmth.
