Sudden loss of memory, forgetfulness, poor understanding of the subject,
apathy for studies are some of the symptoms of Mental Fatigue. This test is
conducted with the help of a machine called 'Mental Fatigue Tester''. Normally
during 8 to 21 years of developing age, the physical, mental and intellectual
growths are taking place simultaneously. Sometimes this might lead to
imbalance in growth at mental or intellectual level, resulting in mental fatigue.
In effect, memory becomes weak or one can not pay due attention to study or
mental work.'
There is a small flickering lamp (LED in this case) on the stage inside the
machine. The frequency of the flicker can be changed and is displayed by the
frequency counter. The child observes the flicker through the window of the
machine and frequency is slowly increased till the child observes the flicker as
a continuous glow. This is say initial frequency. Now the child is asked to
perform a mental task e.g. solving a few math calculations or writing extracts
etc. After this task, again s/he is tested for observing the flicker. This is the
final reading. If the mental fatigue is present, the final frequency observed is
less than the initial one.
With the help of this test, the parents understand the child in proper
perspective and carry out remedial measures, which the researchers suggest
after the test.
