KUPHELE IXESHA -Abantwana abachitha ixesha elingaphantsi kweeyure ezimbini ngosuku kwizikrini benza ngcono kwimemori, ukucinga kunye neemvavanyo zolwimi kunabantwana abasebenzisa izikrini ngakumbi, kufunyanwa isifundo esikhulu.
Phantse isibini kwabathathu abantwana base-US bachitha ngaphezulu kweeyure ezimbini ngosuku bejonga izikrini, uhlalutyo olutsha lwamanqanaba omsebenzi alufumanayo. Kwaye abo bantwana benza kakubi kwimemori, ulwimi kunye kwiimvavanyo zokucinga kunokuba abantwana abachitha ixesha elincinci phambi kwesixhobo, uphononongo lwabantwana abaneminyaka eyi-4,500 8- ukuya kwi-11.
Ukufumana, ukupapashwa kwi-intanethi kaSeptemba 26 kwi ILancet yaBantwana kunye neMpilo yaBafikisayo, ii-bolsters zixhalabisa ukuba ukusetyenziswa okunzima kwee-smartphones, iitafile okanye iithelevishini zinokwenzakalisa iingqondo ezikhulayo. Kodwa ngenxa yokuba uphononongo lubamba umfanekiso omnye ngexesha, akukaziwa ukuba ixesha elininzi lesikrini linokwenzakalisa ukukhula kwengqondo, iingcali zilumkise.
Abaphandi basebenzise idatha efunyenwe kubantwana kunye nophando lwabazali ngexesha lesikrini yemihla ngemihla, ukuzivocavoca kunye nokulala, ukuqokelelwa njengenxalenye yomzamo omkhulu obizwa ngokuba yiAdolescent Brain Cognitive Development Study. Amandla okuqonda nawo avavanywa kolo phando lukhulu. Njengophawu lomlinganiso wesifundo esitsha, abaphandi basebenzise izikhokelo zobungcali ezisethwe kwi-2016 leyo ucebise ukuba angabi ngaphezu kweeyure ezimbini yexesha lokuzihlaziya ngokusemva kwemini, iyure yokuzivocavoca kunye naphakathi kwethoba kunye ne11 iiyure zobusuku bokulala.
Ngokubanzi, iziphumo zinxulumene, utsho uJoquy Walsh, ugqirha wezomzimba owayeselwazini ngelo xesha besesibhedlele saBantwana kwi-Eastern Ontario Research Institute eOttawa, eCanada. Iipesenti ze-5 kuphela zabantwana eziye zahlangana kuzo zontathu ezi zikhokelo ngexesha lesikrini, ukuzivocavoca kunye nokulala, uhlolo olutyhiliweyo. Amashumi amabini anesithoba eepesenti yabantwana awakhange ahlangane nasiphi na isikhokelo, oko kuthetha ukuba "bafika phantsi kweeyure ezilithoba, balale kwizikrini ixesha elingaphezulu kweeyure ezimbini kwaye abakasebenzi ngokwasemzimbeni, U-Walsh uthi. "Oku kuphakamisa iflegi."
Ngokomndilili, abantwana kwisifundo bachitha iiyure ze-3.6 ngosuku besebenzisa izikrini zemidlalo yevidiyo, iividiyo kunye nolunye ulonwabo. Abantwana abachitha ixesha elingaphantsi kweeyure ezimbini kwizikrini befumana amanqaku, ngokomyinge, malunga neepesenti ze-4 ngaphezulu kwibhetri yovavanyo olunxulumene nokucinga kunabantwana abangazange bahlangane nasiphi na isikrini, ukuzivocavoca okanye isikhokelo sokulala, abaphandi bafumene.
"Ngaphandle kokujonga okwenziwa ngabantwana ngezikrini zabo, sibona ukuba uphawu lweyure ezimbini lubonakala licebiso elihle lokuzuza ukuqonda, utshilo uWalsh, ngoku kwiDyunivesithi yaseBritish Columbia e-Okanagan.
Abantwana abaye bahlangabezana neengcebiso zombini ixesha lesikrini kunye nokulala kuvavanywa ngcono. Xa kucazululwa ngokwabo, ukulala kunye nokuzivocavoca umzimba akubonakali ngathi kuphembelela iziphumo zovavanyo
Isifundo asinakuthetha ukuba ixesha lescreen- okanye ukungabikho kweminye imisebenzi-izakhono zokucinga ezithoba kubantwana. “Akwazi ukuba yeyiphi yenkukhu kwaye yeyiphi iqanda apha,” ulumkisa ugqirha wezingane uMichael Rich weSibhedlele saBantwana saseBoston. Kungenzeka ukuba abantwana abalumkileyo kunqabile ukuba uchithe ixesha elininzi kwizikrini, utsho.
Ukukhangela ukuba ityala lisuswe ngokucacileyo yinto ethile ebulala "i-herring ebomvu," kusho u-rich. Unobangela wolwalamano kunye nomphumo oqhelekileyo uhlala ungekho kwindlela yokuziphatha kwabantu kunye nophuhliso. Endaweni yokuthetha, "kufuneka sivumelanise oko sikufunda kwisayensi sikusebenzise umntwana."
Ngokujonga indlela yokuziphatha ngokudibeneyo, iziphumo zibonelela ngokujonga ngokubanzi impilo yabantwana, enye efuneka kakhulu, utshilo u-Eduardo Esteban Bustamante, unesiologist kwi Dyunivesithi yase-Illinois eChicago. “Asazi okuninzi ngoku malunga nokuba ezi ndlela zokuziphatha zinxibelelana njani ukuze zibe nefuthe ekukhuleni kwengqondo yabantwana,” utshilo.
Isifundo sokuPhuhliswa kwengqondo yeAdolescent sityatyelwe ukuqhubeka nokuqokelela idatha efanayo kwezi ntsapho kude kube yi-2028. "Ndichulumancile kukubona ukuba olu luhlu lophando luya phi," utshilo uBustamante.
