Origins of smile and laughter: A preliminary study
چکیده انگلیسی

To present fundamental data, spontaneous smiles and spontaneous laughs (smiles accompanied by vocal sounds) were cross-sectionally observed in 10 newborn infants and longitudinally observed in six infants. Unilateral spontaneous smiles were more common than bilateral smiles in neonates, but by 2 months almost all spontaneous smiles were bilateral. All spontaneous laughs were bilateral. “Spontaneous smile” and “Spontaneous laugh” might be different behaviors from the beginning.
