Iyintoni imfihlelo yevumba elimnandi leentsana ezisanda kuzalwa?

Ngaba ukhe waliva ivumba losana oluncinane, kwiinyanga zalo zokuqala?
Wonke umntu okwenzileyo oku uyaqinisekisa ukuba lelinye lawona mavumba amnandi! Kutheni, Terry?

Ivumba lomntwana linika umama imvakalelo efanayo naleyo esiyivayo xa silambile kwaye sisitya. Okanye indlela elivakalelwa ngayo ikhoboka lazo xa lifumana into elikhoboka layo.

Ivumba lomntwana osandula ukuzalwa yikhemikhali etsalela umama kumntwana kwaye ivule indawo yomvuzo wengqondo esebenzayo xa sisitya into esiyithandayo okanye esiye saba likhoboka layo.

Abaphandi bathi xa ibhinqa livakalelwa, ngokubanzi, lifuna "ukutya" umntwana ezandleni zakhe, nokuba lo mfazi akayena unina, le mvakalelo iyinto eqhelekileyo. Yimpendulo eqhelekileyo yebhayoloji enxulunyaniswa nomvuzo wendawo ye-neural yengqondo.

Inkcazo yesayensi ithi ukusebenza kwale ndawo kukhupha emzimbeni i-hormone dopamine, enoxanduva lokonwaba, ukuphumla kunye nolonwabo.

Uphononongo lubonisa ukuba ivumba leentsana ezisandul’ ukuzalwa lidlala indima ekukhuleni kweempendulo zeemvakalelo kwaye likhuthaza umama ukuba amkhathalele umntwana kwaye limkhuthaza ukuba ancancise kwaye amkhusele umntwana wakhe kuyo nayiphi na ingozi.
