Kungani ukukhala komuntu ngokushesha ayimkhangi yethu?

Lapho uhleli a stuffy enqoleni isitimela ngesikhathi rush ihora, wena onemibuzo akulona ukuntuleka ukutholakala. Uzimisele sibekezelele izixuku zabantu ukumpintsha ezidlulileyo, kungekho conditioning air kanye ukukhathala yangasese. Kodwa ngesikhathi usana endaweni ethile eduze egcwele ukukhala, kuba kuwe sokuhlushwa babulawa zokuziphatha. Kusukela manje kuqhubeke ukugxila lokhu yinhlama kancane abamemezayo futhi ufuna ukuqeqesha athule. Ake sixoxe kungani ukukhala ngakho edonsela ukunakekela kwabantu.

Isici eyingqayizivele Screams womuntu

Ososayensi bezinzwa eNew York University muva wathola ukuthi ukukhala komuntu inesimiso eyingqayizivele, okuyinto oyenza hhayi kuphela ezindaweni sokuzwa zobuchopho, kodwa futhi endaweni obhekene nokwesaba. Uma ucele omunye isingezansi ibonwe obedlula ngendlela emgwaqeni ukuchaza ukukhala, ngiqinisekile eziningi izogxila ivolumu iphimbo umsindo. Ukuxhumana, sivamile ukhethe ibanga izwi futhi buviyoviyo of nye thuthukile niningwane. Lapho indoda ekhala, efuna ngempela izwiwe. Mhlawumbe, ukuthi lokho kutshela engozini, futhi-ke ngempela kungaba wusizo buyinqqikithi yekuchumana.

experiment Inqubekela

Abacwaningi waseNew York esetshenziswa ukukhala amavidiyo ku-YouTube, futhi bakhangwa amavolontiya. Ngenxa yalokho, kwatholakala ukuthi kunyakaza umsindo ngokushesha ukufinyelela ibanga elithile bohlu ezwakalayo. Nakhu omunye balolu cwaningo, uprofesa emkhakheni wezokusebenza kwengqondo uDavide Poppel: "Ngenxa yalokho zokuhlolwa wethu sathola ukuthi ukukhalela luthathe wonke nasembonini spectrum sokuzwa. Siye ihlolwe ezihlukahlukene umsindo futhi waqiniseka ukuthi endaweni lapho zikhona, uhlukile zazo. " Qaphela ukuthi abacwaningi beqhathanisa Screams, ukucula kanye nolimi olukhulunywa (kuhlanganise ngezinye izilimi).

I ohambisana nokumemeza, imoto alamu efanayo?

Okuxakayo ukuthi la alamu (isb, imoto alamu) kuthinte endlebeni yomuntu kanye ukukhala zasendle. Lezi imisindo kukhona impahla ezivamile, esibizwa impendulo imvamisa, eveza ngokushesha kangakanani umsindo eshintsha umthamo yayo. inkulumo Human ngokuvamile angena uhla 1 Hz, ekhala futhi wenhlabamkhosi ingahluka kubanga eliphakathi 30 futhi 150 Hz. Lapho sivivinywa isifundo New York babuzwa ukuthi yiziphi umsindo kwakubonakala esabeka kunazo zonke njalo ngokuthi amasignali nge imvamisa high impendulo.

Kwenzekani ebuchosheni?

Abacwaningi baye baphawula umsebenzi ubuchopho amavolontiya kuyilapho ukulalela ememeza. Lapho le ndlela iye yasetshenziselwa-magnetic resonance imaging. Ngenxa yalokho, izikhonzi bandisa inkonzo nobuchopho amygdala etholakele. Lokhu ingxenye yobuchopho obhekene ekucubunguleni imizwa nokwesaba. Hlale ukhumbula lokhu ngokuzayo ucabanga ukubukela ibhayisikobho ethusayo.
