Ayikho enye inkulumo ye-feline ethinta abantu ngendlela efana neyesikhala sekhati. I-purr ingazwakala kodwa ingakhulumi, noma iqhudumise nge-gusto yeloli likaMack. Ngenkathi abantu abaningi becabanga ukuthi i-purr isebenza njengokubonisa ukwaneliseka kwe-kitty, umsindo ongaqondakali - ukuthi uyadalwa kanjani, futhi kungani-akuyona into elula.
Indlela ama-Cats Purr
Ochwepheshe abakazange baphakamise indlela eqondile eyenza i-purr, eyenzekayo kokubili ukuguqula nokukhipha umsindo ozwakalayo.
Amakati alahlekelwa yi "meows" (exhale) ngenxa yokulimala ahlale ekwazi ukuhlanza, kepha amakati anesifo sokukhubazeka alahlekelwa yi-purr. Kubonakala sengathi imisipha yangaphakathi yama-laryngeal, elawula ukuvula nokuvala isikhala phakathi kwezingcingo zamagama (glottis), yenza umsindo ozwakalayo. Ucwaningo luye lwabonisa ukuthi lokhu kuhamba kwemisipha yomsindo kulawulwa yi-"oscillator ye-neural" eyingqayizivele ebuchosheni bekati.
Ukuxhumana kwe-Kitten
I-purr's mother's purr isebenza njengebhektha-viboni esitshela izingane zakhe ezingaboniyo nezisithulu ezingabantwana bayo. Ama-kittens aqala ukuhlanza ngezinsuku ezimbili ubudala.
I-Purring ingaba isici sezinyosi eziqondene nezinsana ezigcinwa ngabantu abadala. Izinsana zivame ukuzibandakanya ekuziphatheni kokugwedla ngenkathi zihlanza. Ukugcoba ama-kittens, noma ukuhamba ngezinyawo eziphambili, ngokumelene namabele omama-cat ukuhambisa ubisi lwakhe ukuba lugele njengoba belalisa. Amakati amadala avame ukugcina lokhu kuziphatha, ikakhulukazi uma befuna.
I-Feline Smile
Abantu bavame ukucabangela ukuhlanza ukubonisa uthando, futhi ngokusobala kuyithuluzi lokuxhumana. Amakati kanye nama-kitten akavamile ukuhlanza lapho bewodwa. Ama-Purrs ahloselwe amanye amakati noma abantu. I-purr ichazwe ngokuthi i-feline efana nokumomotheka, okwenza kube nomqondo omuhle. Ngempela, abantu bayamamatheka ngenxa yezizathu eziningi - injabulo, izinzwa, ukwesaba - futhi ukumamatheka (noma i-purr) akusho neze injabulo.
Ama-Purrs agxuma ngazo zonke izinhlobo zezikhathi, ngisho nalapho uKetty esaba noma ebuhlungu. Abanye abaziphatha kahle bakhombisa ukuthi i-purr iyisibonakaliso sokuzithoba okubonisa amanye amakati nabantu ukuthi, "Angiyikusongela" noma, "ngiduduze." Kungenzeka ukuthi lokho kusetshenziswe kokubili ngesikhathi sokugcwala ukuveza injabulo, futhi ngezikhathi zokucindezeleka ekunciphiseni ukucindezeleka. Uma ikati lakho lifika kuwe ngama-paws wokugcoba kanye ne-purrs ekhangayo, mhlawumbe leyo yindlela yakhe yokukubiza ngokuthi "umama."
Akuwona wonke ama-cats purr. Lokhu akusho ukuthi bacindezelekile noma bajabule. Kungase kusho nje ukuthi ikati lihle kakhulu futhi lizizwa lingekho isidingo sokuhlanza. Emndenini wezinkampani eziningi, inkokhelo enamandla kakhulu yokulawula ingase ifune kancane ngenxa yokuthi isivele iphethe, kuyilapho enye i-kitties ingaphezulu ngokuchasene nesimo sakhe.
Ukuphulukisa ama-Purrs?
Abanye ososayensi bathi inhlanzi iyasebenza njengendlela yokuphulukisa. Ngokusho kwe-Scientific American, "I-Cats purr ngenkathi kokubili ukuphuza nokuphumula ngokwephethini eguquguqukayo kanye nemvamisa phakathi kuka-25 no-150 Hertz. Abaphenyi abahlukahlukene baye babonisa ukuthi amafrimu aphikisayo kulolu hlu angathuthukisa ubukhulu bamathambo futhi akhuthaze ukuphulukiswa."
Amathambo e-feline aphulukisa ngokushesha kakhulu kunezinye izilwane ezincelisayo, futhi emithini yomuntu, ukudlidliza kwemvamisa efanayo ehlathini kubonakala sengathi kuphuthumayo ukuphulukisa.
Kungenzeka yini ukuthi i-purf ye-feline ibe yinto yokuziphendukela kwemvelo yamakati ethu?
Ama-Purrs akhethekile
Amakati amancane kuphela anekhono lokuhlanza, kanti izihlobo ezinkulu zekhati njengezingonyama ziyakwazi ukubhonga. Ama-tigers ane-"silence" ephansi ye-frer purr engaphezu kwezinga lokuzwa futhi okwenzeka ngesikhathi esifanayo. Lelizwi elizwakalayo le-tiger linamandla okufiphala kancane kancane.
Amakati ethu asekhaya nawo anamandla okungaqondakali-ahlanzekile. UDkt. Karen McComb ungumlobi oholayo wocwaningo e-University of Sussex eNgilandi, okwakushicilelwa encwadini ye-Current Biology ngo-2009. Wachaza ukuthi "ukucela isikhala" kunemisindo yansuku zonke, eyayinezikhathi ezifanayo zokukhala umntwana wesintu.
Leli phunga elikhethekile elinomvuthwandaba ophezulu ohlanganisiwe latholakala ukuthi lisetshenziswe ngamakati esifundweni njengendlela ephumelelayo yokuthola abanikazi bembhedeni ukuba bagcwalise isitsha sokudla.
Ngokusobala, ukukhala kuhlale kusezingeni eliphansi ekuhlanzeni okujwayelekile, kepha amakati anesihlobo esiseduze nabanikazi bawo abonakala efundela ngokugqamile ukuthi yini eyenza abantu baphendule. Smart kitties, eh ?!
Kungakhathaliseki ukuthi kungani ikati lisizathu se-purr, thina bantu siyajabula ngokuzwakalayo (ngaphandle uma ekuseni kakhulu ekuseni). I-purr iyillaby feline ekhuthaza umculi kanye nomphefumulo womlaleli.
