Wonke umqondisi ozihloniphayo oshiya uchungechunge oluthatha uchungechunge noma i-thriller yezinhloli, uzama ukufaka endaweni yakhe yesikhala nge polygraph noma okungenani ukukhulunywa ngakho. Ngakho-ke, kubonakala sengathi isheke kwi polygraph akunakwenzeka, futhi kungenzeka yini ukukhohlisa umtshina wamanga - idivaysi enesisindo sezinzwa eziqondile ezilinganisa zonke izimo zomzimba wethu? Kuvela ukuthi le ndlela ayiyona ephelele njengoba sinikezwe kumafilimu.
Iyini i-polygraph?
Umdwebo we-polygraph wabonakala ngawo-1920, kodwa leli gama lakhulunywa okokuqala ngo-1804. UJohn Hawkins ubizwa ngokuthi idivaysi, okwenza kube lula ukudala amakhophi athile amatheksthi ngesandla. Futhi kamuva leli gama lisetshenziselwa ukukhomba umtshina wamanga. Amadivaysi okuqala afakwe izinzwa kuphela ezirekhoda ukuphefumula nokucindezela. Kodwa i-polygraphs yesimanje ingakwazi ukurekhoda kuze kube yimingcele engama-50 yemvelo. Ngaphandle kwezinkomba ezibalwe, lokhu kufaka phakathi izinguquko ekujuleni nokuvama kokuphefumula, idatha nge-palpitation, palpitation, ukukhwabanisa komzimba, izimpendulo ze-pupillary, imvamisa yokukhanya, futhi ngezinye izikhathi ubhalise umsebenzi kagesi wengqondo. Akumangazi ukuthi le divayisi ibonakala iyindlela yokugcina ekufuneni iqiniso. Phela, kukholelwa ukuthi uma umuntu elala, izwi lakhe lizoshintsha, izandla zakhe ziyokhukhuma, ubukhulu bayo buzoshintsha, ukushisa kwesikhumba eduze kwamehlo akhe noma ukushaywa kwenyuka kuzokwandisa, futhi i-polygraph inakho konke okudingekayo ukulungisa lezi zinguquko.
Kungenzeka yini ukukhohlisa umtshina wamanga?
Abaningi bazi kahle ukuthi bangakhohlisa kanjani ukuze bakholwe wena. Kumele uqale ukholelwe emangeni akho, uma lokhu kwenzeka, khona-ke kuyoba nzima kakhulu ukukubona. Kodwa kungenzeka yini ukukhohlisa i-polygraph (amanga umtshina) ngale ndlela? Ososayensi baseMelika abavela eNorthwestern University nabo banesithakazelo kulokhu kukhishwa, futhi bahola izifundo eziningana, imiphumela eyabhekana nokwehluleka okukhulu kwidumela le polygraph elingenakwenzeka. Yiqiniso, befuna kuphela ukuphendula umbuzo ukuthi kungenzeka yini ukukhohlisa umtshina wamanga, futhi abahlose ukushicilela le ndlela, kodwa benza ngokuzikhandla.
Ukuhlukanisa izihloko zibe ngamaqembu amabili, basikisela ukuthi wonke umuntu akhulume amanga. Abahlanganyeli beqembu lokuqala kuphela abahlolwe ngokushesha, kanti okwesibili - banesikhathi esincane sokulungiselela. Abahlanganyeli eqenjini lesibili baphumelela ukudlula umtshina wamanga, baphendule imibuzo njengoba kufanele - ngokushesha futhi ngokucacile. Ngenxa yesifundo, abacwaningi bancoma ukuthi amaphoyisa aphenywe ngokushesha ngemuva kokuboshwa, ngaphandle kokunikeza isikhathi sobugebengu ukulungisa indaba. Nakuba, mhlawumbe, iziphathimandla zomthetho zase zikwazi kakade lezi zingu-nuances.
Futhi okumangalisa kakhulu ukuthi ukuhlolwa nge-polygraph, ngokujwayelekile, akusiyo nje isayensi. Ngokuvamile, lokhu akuyona isayensi eningi njengezobuciko, ngoba kubalulekile hhayi kuphela ukulungisa imiphumela, kodwa futhi ukuyihumusha kahle. Futhi lo msebenzi awulula futhi udinga isitifiketi esiphakeme sesazi.
