Ubesabe kokuba ekitazana, hhayi kuphela abantu, kodwa futhi amagundane, nezinkawu. Ososayensi namanje ukuthi kungani umphumela esikhumbeni ihlanganisa kwezinye izindawo kubangela injabulo yomuntu, squeals uhleko, kanye kungani lezi umuzwa reflex azizange zinyamalale e inqubo yokuziphendukela kwemvelo. Namuhla, njengoba umthetho, abantu bakitaza nomunye ihlaya, futhi nje ukwenza umuntu hleka. Kodwa kuvela, akajabuli ngakho.
izinyawo silume - sokuhlushwa elicwengiweyo
US sokusebenza kwengqondo Christina Harris kanye isifundo. Yena izithombe abantu ngesikhathi tickling wafica Inkulumo ngobuso babo akuyona injabulo nokuhlupheka. Kulesi sisekelo, singaphetha ngokuthi le ndoda Nokho bakitaza, futhi uyahleka, kodwa azizwa awunakuthokoza nokuhlushwa. Qinisekisa lokhu futhi abanye amaqiniso angokomlando. Ngakho, amaRoma endulo ndlela izinyawo tickling sokuhlushwa. Emagatsheni isisulu ayethe njo esimweni umile, futhi umuntu ngamunye odlulayo kungaba bhala izinyawo zakhe elingenalutho. Foot Itchy ekhiqizwa nezindlela ezingcono, isibonelo, unyawo afafazwe ngosawoti, okuyinto kamuva ikhotha imvu.
Kungani-ke laughable?
UCharles Darwin kanye wasikisela ukuthi tickling izinyawo noma ezinye izindawo umzimba kusiza nokuqinisa isibopho nomphakathi. Ngokuphambene, odokotela bengqondo zanamuhla oyikholelwayo ukuthi umuzwa eyenziwe ke - uhlobo reflex ezenzelwe ukuvikela izindawo sengozini zomzimba. Izindawo ezizwelayo kakhulu ukuhlekisa - izinyawo, emakhwapheni, okhalweni esifundeni. Lesi senzo ibonwa umzimba njengenhlangano umfutho kwangaphandle, lapho kufanele kugwenywe. Yingakho sizama ibuyisele Dodge lapho sithinte bezindawo ebucayi kakhulu.
guys Abaningi bacabanga amantombazane tickling izinyawo nge ukukhanya feather limnandi kakhulu, futhi ngenxa yalokho ngokuvamile bakwenza. Mhlawumbe, nakuba ngendlela ongasinika ubumnandi. Kodwa lapho umuntu echayeke tickling eqinile ukuthi ukhiqiza squeals uhleko, imizwa emnandi yena neze azizwa. Odokotela bengqondo bakholelwa ukuthi okuholela ukuhlekisa uhleko - kuba reflex okumsulwa. Omunye umbono ukuchaza ngokuthi uhlobo ukuphumula umzimba: lokuqala umuntu enomuzwa kokwesaba, futhi eqaphela ukuthi akukho ingozi, iqala ukuhleka. Darwin, Nokho, lesi simo ahlanganiswa ukuncokola.
Kodwa kungani tickling uqobo akusho ukukhiqiza uhleko? Aristotle wacabanga ngawo. Weza esiphethweni sokuthi yisiphi isinyathelo lovela indoda ngokwayo, akuyona eziyingozi, ngakho-ke engayinaki umzimba ngoba. conjecture Aristotle kuqinisekiswa abacwaningi yesimanje. Omunye sokuhlola, ekhiqizwa ngosizo-magnetic resonance imaging wabonisa ukuthi ubuchopho babantu ngubani bakitaza omunye, ubekhona kakhulu ngaphezu kwalabo bakitaza yena. Okuningi kuxhomeke ekutheni ukufunde ngubani ngokuqondile kukuthinta kanjani. Ngokwesibonelo, abazali bezingane tickling izinyawo ubulala izingane uhleko. Kodwa zokukhwabanisa efanayo izingane angajwayelekile noma ezingathandeki kubantu umzimba uqala ukwenqaba simelane umthelela.
