Txhua tus tswj hwm tus kheej uas tua ib qho kev sib txuas los yog cov neeg soj xyuas cov tub sab, nws xav kom muaj xws li hauv nws qhov kev tsim tawm nrog ib lub polygraph los yog tsawg kawg yog ib qho ntawm nws. Yog li ntawd, nws zoo li tias daim tshev rau lub polygraph yog unmistakable, thiab yog nws tau dag siab dag ntes - ib tug ntaus nruab nrog ib pawg ntawm cov sensors uas ntsuas txhua txhua lub cev ntawm peb lub cev? Nws hloov tawm hais tias qhov no tsis yog qhov zoo tag nrho raws li peb tau hais hauv cov duab.
Dab tsi yog ib tug polygraph?
Lub tsab ntawv ntawm lub polygraph tshwm nyob rau hauv lub xyoo 1920, tab sis lub sij hawm twb thawj hais nyob rau hauv 1804. John Hawkins hu ua lub tshuab ntaus ntawv, uas ua rau nws tsim tau cov qauv luam tawm ntawm cov ntawv nyeem. Thiab tom qab no lub sij hawm no yog siv los ua ib qho dag ntes. Thawj cov cuab yeej tau nruab nrog tsuas sensors uas sau cov mem tes ua pa thiab siab. Tab sis niaj hnub polygraphs tau sau txog li 50 physiological tsis. Ntxiv rau cov teev tseg, qhov no suav cov kev hloov hauv qhov tob thiab qhov ua tsis taus pa, cov ntaub ntawv ntawm palpitation, palpitation, lub ntsej muag txawv, cov lus teb rau cov menyuam kawm ntawv, qhov ntswg zaus, thiab qee zaum sau npe hluav taws xob ntawm lub hlwb. Nws tsis yog xav tsis thoob tias lub cuab yeej zoo li yog lub xeem chaw nyob rau hauv kev tshawb nrhiav qhov tseeb. Tom qab tag nrho, nws ntseeg tias yog ib tug neeg hais lus, nws lub suab yuav pauv, nws txhais tes hws, nws cov menyuam kawm ntawv loj yuav hloov, qhov kub ntawm daim tawv nqaij nyob ze nws lub qhov muag lossis lub plawv yuav nce, thiab lub polygraph muaj txhua yam tsim nyog los kho cov kev hloov no.
Puas yog nws ua tau kom dag tau cov lus dag?
Muaj ntau tus paub zoo tias yuav ua licas thiaj li paub tias lawv ntseeg koj. Koj yuav tsum ntseeg thawj zaug ntawm koj cov lus dag , yog tias qhov no tau tshwm sim, ces nws yuav nyuaj rau nws paub. Tab sis yog nws tau dag tau ib tug polygraph (lie detector) li no? Cov kws tshawb fawb ntawm Northwestern University kuj tau xav ua qhov teeb meem no, thiab coj ntau cov kev tshawb fawb, cov kev tshwm sim uas tau cuam tshuam ib qho kev lag luam loj heev rau lub koob npe ntawm ib qho kev ua yuam kev loj heev. Tau kawg, lawv tsuas xav xav teb cov lus nug seb nws puas tau dag tau dag ntes, thiab lawv tsis tau npaj yuav luam tawm hom no, tab sis lawv tsis ua raws li lawv tau ua.
Muab faib ua ob pawg, lawv pom tias txhua tus neeg hais lus tsis tseeb. Tsuas yog cov neeg koom ntawm thawj pab pawg tau raug sim tam sim ntawd, thiab lub thib ob - muaj me ntsis sij hawm rau kev npaj. Cov neeg koom tes hauv pawg thib ob tau tswj hwm tau qhov kev dag lub tswv yim, teb cov lus nug raws li nws yuav tsum tau ua - sai thiab meej. Raws li txoj kev tshawb nrhiav, cov kws tshawb fawb tau pom zoo tias tub ceev xwm yuav tsum tau tshawb nrhiav tam sim ntawd tom qab raug kaw, tsis tas muab lub sij hawm txhaum los npaj cov lus dab neeg. Txawm hais tias, tej zaum, cov tub ceev xwm tau paub txog cov nuances no.
Thiab qhov tseem ceeb tshaj plaws yog tias kev sim nrog ib tug polygraph, nyob rau hauv dav dav, yog tsis ncaj qha scientific. By thiab loj, qhov no tsis yog ntau qhov kev tshawb txuj ci li ib daim duab, vim nws yog ib qho tsim nyog tsis yog los txhim kho cov kev tshwm sim xwb, tab sis kuj yog los txhais cov lus kom yog. Thiab txoj hauj lwm no tsis yog yooj yim thiab yuav tsum tau muaj kev tsim nyog ntawm ib tug kws kho mob tshwj xeeb.
