Sida loo akhriyo natiijadaada

  • Halka buluuggaagu ka bilaabmo: midabka ay jawaabahaagu uga wareegeen "cagaar" una noqdeen "buluug". Midabku waa xagasha uu midabku kaga yaal goobo midabeed; waxaan adeegsannaa goobta midabeed ee OKLCH, oo tallaabooyinka isku midka ahi ay u muuqdaan kuwo qiyaastii isku heer u kala duwan. Miisaankeenna, cagaarku wuxuu u dhow yahay 140°, buluugguna 250°.
  • Saddexda muunadood ee midabka: mid kaa xadkaaga wax yar ka cagaaran, xadka laftiisa, iyo mid wax yar ka buluugsan. Saaxiib ayaa kan dhexe ugu yeeri kara magaca kale.
  • Dhibcaha khaladka: inta ay midabbada safafkaagu uga qalloocdeen kala horrayntooda saxda ah. Midab kastaa wuxuu helaa dhibcaha farqiga u dhexeeya iyo labada deriskiisa, iyadoo 2 laga jarayo; sidaas darteed saf si qumman u kala horreeya wuxuu helaa 0. Inta uu hooseeyo ayaa fiican.
  • Giraanta: dhammaan midabbada goobada midabeed, mid kastana midabkiisa. Qodax dheer waxay ka dhigan tahay isku qasid badan oo midabkaas ah; "isku qasidda ugu badan" waxay tilmaamaysaa aagga ugu badan.

Xadkaagu jawaab sax ah ama khaldan ma laha. Dhibcaha khaladku way leeyihiin: 0 ayaa qumman. Midkoodna ma aha natiijo caafimaad.

Buluuggaygu ma la mid yahay kaaga?

Dadku meelo kala duwan ayay xadka u dhexeeya cagaarka iyo buluugga dhigaan. Daraasadaha midabbada "gaarka ah", cagaarka saafiga ah iyo buluugga saafiga ah ee dadku doortaan aad bay ugu kala duwan yihiin, sidaas darteed buluugga qof ayaa cagaar u noqon kara qof kale [1]. Luqaduhuna way ku kala duwan yihiin: sahan lagu sameeyay 120 luqadood, 68 ka mid ahi waxay hal eray u adeegsadaan cagaarka iyo buluugga [2]. Sidaas darteed xadka saaxiibkaa wuu ka duwanaan karaa kaaga.

Xog kooban

  • Yaraanta aragga midabka: qiyaastii 8% ragga iyo 0.4% dumarka asal ahaan ka soo jeeda Yurub waxay qabaan yaraanta aragga midabbada cas iyo cagaar; sidoo kale 4 ilaa 6.5% ragga asal ahaan ka soo jeeda Shiinaha iyo Jabaan [3]. Boggan imtixaan uma aha xaaladdan.
  • Erayada iyo midabbada: Af-Ruushku wuxuu leeyahay erayo aasaasi ah oo kala gaar ah oo loogu talagalay buluugga khafiifka ah iyo buluugga madow. Hal daraasad yar, dadka ku hadla Af-Ruushku si ka dhakhso badan ayay u kala garteen laba buluug markii ay labada midab kala dhinac ka ahaayeen xadkaas; dadka ku hadla Af-Ingiriisiguna saamayntaas ma muujin [4].
  • Imtixaanka kala hormarinta caanka ah: Imtixaanka 100ka midab ee Farnsworth–Munsell, oo rugaha caafimaadka lagu isticmaalo, wuxuu leeyahay 85 dabool oo midab leh oo ku jira 4 saxaaradood. Qaybta 2aad ee imtixaankeenna isaga ayaa dhiirrigelisay, balse waxaan leenahay midabbo noo gaar ah iyo daboollo ka yar.
  • Da'da: imtixaankaas caafimaad, kala hormarinta midabku waxay ugu fiican tahay qiyaastii da'da 19, dabadeedna si tartiib ah ayay da'da ula sii adkaataa (382 qof oo araggooda midabku caadi yahay) [5].
  • Midabbada mugdiga leh: sahan internetka ah oo 1,401 qof laga qaaday oo ku saabsanaa sawirka "dharka", 57% waxay u arkeen buluug iyo madow, 30% na caddaan iyo dahab [6]. Sahan internetka ah oo ka ballaaran ayaa helay inta badan aragti ka soo horjeedda [7], sidaas darteed dadku qiyaastii laba ayay u kala qaybsan yihiin.

Sida uu u shaqeeyo imtixaanka aragtida midabka

  1. Buluug mise cagaar? Hal midab ayaa mar kasta soo baxaya, isagoo dul saaran cawl dhexdhexaad ah. Taabo Cagaar ama Buluug, ama riix ← iyo →. Ku jawaab aragtidaada koowaad.
  2. U soo dhowaanshaha xadka. Laba taxane oo midabbo ah ayaa isku mar socda; mid wuxuu ka bilaabmaa dhinaca cagaarka, midna dhinaca buluugga, mid kastaana wuxuu leeyahay 12 midab. Jawaabta "cagaar" waxay taxanahaas u dhaqaajisaa dhinaca buluugga, jawaabta "buluug" na dhinaca cagaarka; tallaabooyinkuna mar kasta way yaraadaan markaad beddesho jawaabtaada. Labadu waxay ku kulmaan agagaarka xadkaaga.
  3. Midabbada kala hormari. Markaas waxaa lagu siinayaa 4 saf oo midkiiba ka kooban yahay 12 midab. Saf kastaa labada geesoodba wuxuu ku leeyahay midab go'an; jiid midabbada ama taabo laba si aad isu weydaarsato, ilaa midabbada safku si habsami leh isu raacaan. Waqti laguma xaddidayo.

Dhammaan 52 midab ee qaybta 2aad hal mar ayay ku wareegaan goobada midabeed, iyagoo isu jira qiyaastii 6.9° oo midab ah, dhalaalkooda iyo xoogga midabkooduna isku mid yihiin; sidaas darteed midabka keliya ayaa is beddela. Xadku waa barta 50% ee qalooc laga waafajiyay jawaabahaaga. Dhibcaha khaladku waxay raacaan xeerka imtixaanka 100ka midab.

Maxaa saamaynaya natiijadaada?

  • Shaashaddaada. Shaashaduhu waxay ku kala duwan yihiin midabka, dhalaalka iyo dejimaha. Habka habeenkii, shaandhooyinka iftiinka buluugga, "true tone" iyo shaashad daciif ahi dhammaantood midabbada ayay huruud u riixaan. Xitaa samayaha imtixaanka caafimaad ee 100ka midab wuxuu sheegay in nooc internet ahi aanu go'aan kama dambays ah bixin karin, maadaama shaashaduhu kala duwan yihiin [8]. Natiijooyinka ku barbar dhig isla shaashadda.
  • Qolka. Iftiin xooggan ama midab leh oo kugu hareeraysan wuxuu beddelaa sida shaashaddu u muuqato.
  • Luqaddaada. Erayada aad midabbada ugu isticmaasho waxay qaabeeyaan halka aad xadka dhigto. Luqadaha si gaar ah u magacaaba buluugga khafiifka ah iyo kan madow, ama hal magac ugu yeera cagaarka iyo buluugga, xuduudo kala duwan ayay dhigaan [2][4][9].
  • Da'da iyo daalka. Kala hormarinta midabku way adkaataa marka da'du korodho [5], indhaha daallanna waxay ku adkeeyaan kala saaridda midabbada isu dhow.
  • Aragga midabka. Dadka qaba yaraanta aragga midabbada cas iyo cagaar badanaa safafka qaarkood ayay aad ugu dhibtoodaan. Haddii qaybo ka mid ah imtixaanku kuu muuqdeen wax aan suurtagal ahayn, dhakhtar indhaha ama takhtar aragga ayaa si habboon u baari kara araggaaga midabka.

Waxa imtixaankani kuu sheegi karo iyo waxa aanu kuu sheegi karin

Imtixaanka aragtida midabku wuxuu muujinayaa halka aad shakhsi ahaan ka dhigto xadka u dhexeeya cagaarka iyo buluugga, iyo sida aad si fiican ugu kala hormarin karto midabbo isu eg oo shaashaddan ku jira. Waa ciyaar ku salaysan hawlo cilmi-baariseed. Ma aha imtixaan lagu ogaado indho-la'aanta midabka, ma aha baaritaan caafimaad, mana aha imtixaanka Farnsworth–Munsell laftiisa: dhibcihiisa laguma barbar dhigi karo heerarka caafimaad. Xiriir lama lihin X-Rite ama Munsell.

Haddii aad u malaynayso inaad indho-la'aan midab leedahay, takhtar aragga ama dhakhtar indhaha ayaa kugu baari kara jaantusyo iyo iftiin ku habboon.

Su'aalaha inta badan la isweydiiyo

Buluuggaygu ma la mid yahay buluuggaaga?

Mar walba maya. Marka dadku doortaan cagaarkooda iyo buluuggooda ugu saafiga ah, doorashooyinku aad bay qofba qofka kale uga duwan yihiin; buluugga qof ayaa cagaar u noqon kara qof kale [1]. Imtixaanka aragtida midabka ee Helibrain wuxuu helaa xadkaaga gaarka ah ee u dhexeeya cagaarka iyo buluugga, si aad saaxiibkaa ugula barbar dhigi karto isla shaashadda.

Turquoise-ku ma buluug baa mise cagaar?

Turquoise-ka iyo buluug-cagaarku waxay ku yaallaan xadka u dhexeeya cagaarka iyo buluugga, taas ayaana keenta in dadku isku khilaafaan. Inaad buluug ama cagaar ugu yeerto waxay ku xiran tahay indhahaaga, shaashaddaada iyo luqaddaada: 120 luqadood oo la dersay, 68 waxay hal eray u adeegsadaan cagaarka iyo buluugga [2]. Imtixaanku wuxuu muujinayaa dhinaca aad u janjeerto.

Kani ma yahay imtixaan indho-la'aanta midabka?

Maya. Imtixaanka aragtida midabka ee Helibrain ma baadho indho-la'aanta midabka, waxna kama ogaan karo cudur. Imtixaannada indho-la'aanta midabku waxay adeegsadaan jaantusyo gaar ah iyo iftiin la xakameeyay. Qiyaastii 1 ka mid ah 12 nin ayaa qaba yaraanta aragga midabka [3][10]; haddii aad ka shakisan tahay inaad qabto, u tag takhtar aragga ama dhakhtar indhaha.

Maxay natiijadaydu shaashad kale ugu beddelmaysaa?

Shaashaduhu midabbada si kala duwan ayay u muujiyaan, dejimaha sida habka habeenkii, shaandhooyinka iftiinka buluugga iyo dhalaalkuna intaas ayay sii beddelaan [8]. Xad lagu cabbiray telefoon habka habeenkii shidan yahay wuu ka duwanaan karaa mid lagu cabbiray kombiyuutar la qaadan karo. Isbarbardhig caddaalad ah awgiis, mar kasta adeegso isla shaashadda iyo isla dejimaha.

Kani ma yahay imtixaanka Farnsworth–Munsell ee 100ka midab?

Maya. Qaybta 2aad waxaa dhiirrigeliyay imtixaanka Farnsworth–Munsell ee 100ka midab, waxayna adeegsataa xeerkiisa dhibcaha; hase yeeshee midabbadayadu waa kuwo noo gaar ah, way ka yar yihiin tiradoodu, shaashad ayaana lagu muujiyaa halkii ay ahaan lahaayeen daboollo dhab ah oo lagu eego iftiin caadiyeysan. Dhibcihaya laguma barbar dhigi karo heerarka caafimaad.

Imtixaanka aragtida midabka ee Helibrain runtii ma bilaash baa?

Haa. Imtixaanka iyo natiijadaada oo dhan waa bilaash: isdiiwaangelin, iimayl iyo lacag-bixin midna looma baahna. Helibrain wuxuu dakhli ka helaa abka, kaas oo leh qorshe bilaash ah iyo qorshayaal lacag leh; abka uma baahnid si aad imtixaanka u gasho.
