Tabiiy va aniq fanlar

Odamning diqqatini talab etadigan faoliyati vaqtidagi aqliy ishchanlik qobiliyatini aniqlash.
Hozirgi vaqtda AIQni aniqlash uchun korrektsiyalovchi jadvaldan (Anfimov jadvali) keng foydalaniladi. Bu jadval bilan ishlash aniqlik, tezlik va diqqatni bir joyga jamlashni talab qiladi.
Tajriba davomida ishni sifat va miqdor jihatlari baholanadi. Quyidagi formulalar yordamida tajriba natijalari aniqlanadi.
A - aniqlik koefitsienti,
M- o’chirilgan harflar soni,
N –ko’rilgan harflar soni.
R=A×S R – AIQ. koefisienti,
S – ko’rilgan umumiy harflar soni
O’quvchilarga Anfimov jadvali tarqatiladi. Jadvaldagi 1 ta harfni 4 daqiqa davomida belgilashlari kerak. Bu tajriba jadvaldagi barcha harflar bilan takrorlanadi. Ish davomida tezlik, diqqat va aniqlik talab qilinadi. Belgilangan harflar alohida sanaladi va quyidagi jadval to’ldiriladi.

Ish vaqti	Berilgan harflar	4 daqiqa davomida topilgan harflar soni	Jadvalda mavjud harflar soni	Jami va topilgan harf sonlari farq

Ishning tezligi to’g’risida 4 daqiqa ichida ko’rib chiqilgan belgilarning umumiy miqdoriga qarab, aniqlik esa 4 daqiqa ichida qilingan hatolarning umumiy miqdoriga qarab mulohaza qilinadi.
