Human
multitasking is the apparent performance by an individual of handling more than
one task at the same time. An example of multitasking is students doing homework or mathematics while
watching a Cricket match on TV; women cutting vegetables while talking on
mobile phone and watching a TV serial as well.
Though primarily intended to save time, at times, it could cause more
errors due to insufficient attention.
In
Computing, multitasking is a method
where multiple tasks (processes) are performed during the same period of time –
they are executed concurrently (in overlapping time periods, new tasks starting
before others have ended) instead of sequentially (one completing before the
next starts). The tasks share common processing resources, such as central
processing units (CPUs) and main memory.
Though in a mobile phone, several applications could be running – one
would not be in a position to hear a speech or a song – as one creates a new
mail or a SMS ! that way, multitasking
does not imply parallel execution, but still
more than one task can be part-way through execution at the same time.
Amphibious means able to use either land or water. Ambivalence is a state of having simultaneous
conflicting reactions, beliefs, or feelings towards some object. Stated
otherwise – it is "mixed
feelings" of a more general sort are experienced, or where a person
experiences uncertainty or indecisiveness.
Ambidexterity
is the state of being equally adept in the use of both left and right
hands. It is one of the most famous
varieties of cross-dominance. The degree of versatility with each hand is
generally the qualitative factor in determining a person's ambidexterity. In
modern times, it is more common to find people considered ambidextrous who were
originally left handed and who learned to be ambidextrous, either deliberately
or during childhood.
Sachin Tendulkar bats right, bowls right but uses his left hand
for writing; Sourav Ganguly was left handed batsman, bowled right and uses
right hand for writing. Since many everyday devices (such as can openers and
scissors) are asymmetrical and designed for right-handed people, many
left-handlers learn to use them right-handedly due to the rarity or lack of
left-handed models. The word "ambidextrous" is derived from the Latin
roots ambi-, meaning "both", and dexter, meaning "right" or
"favorable". Thus, "ambidextrous" is literally "both
right" or "both favorable". Many months back, MailOnline had an ‘inkredible’ report on a
Chinese woman who could write with both hands at the same time ~ that too in
different languages.
In
this age of computers and smartphones, some of us are finding it harder and
harder to write properly with one hand, let alone two. But that is no such
problem for Chinese translator Chen Siyuan. She has been amazing onlookers with
her ability not only to write with both hands at the same time, but do it in
different languages - Chinese with one and English with the other. ~ and for
good measure the 24-year-old can also perform the trick with each hand writing
in different directions. Chen, whose name means 'think further', didn't develop
her skill through hours of practice. Instead she discovered it by chance while
trying to save time on large amounts of English homework at her high school in
northern China.
She told People's Daily Online: 'When I was in
high school, I unconsciously wrote with both hands while trying to finish my
homework in a hurry. 'My classmates were curious and tried to imitate me, but
none of them succeeded.' Chen, who later obtained a college degree in English,
now uses her talent to write poetry, two sentences at a time, of course.
A web search reveals that such ambidextrous persons are twice as likely to be hyperactive as their
classmates, researchers found.They are also twice as likely to suffer from
language problems, such as dyslexia. Scientists believe that differences in how
the children’s brains work compared to others could link the problems, but
admit they do not yet understand how. An estimated 600,000 people on Britain
are thought to be ambidextrous, or mixed-handed, as it is also known. The team
behind the research say that teachers and doctors should try to identify those
children who may be at risk of suffering educational or health problems.
