- BACKGROUND
-
- Intelligence tests and IQ scores were
- not as popular as they once were but
- most of us at one time or another
- have done some form of aptitude or
- intelligence test at some stage in
- our lives. You may have done them at
- school or may have sat for one when
- applying for a job.
-
- I.Q. stands for Intelligence Quotient.
- It is calculated by dividing a
- person's theoretical mental age by
- their actual chronological age,
- which is rounded off to the nearest
- month.
-
- If a person's level of achievement is
- equal to the average of a particular
- age group then their IQ score is 100.
- Hence if an 7 year old performs equal
- to the average of a 14 year old then
- their mental age is considered to be
- twice their chronological age.
- In other words they would have an IQ
- of 200.
-
- A person scoring average for their age
- is considered to have an IQ of 100.
- e.g. A 10 year old scoring equal to
- the average 15 year old would be
- considered to have an IQ of 150.
-
- A ten year old scoring equal to the
- average 8 year old would have an IQ
- of 80.
-
- Past the age of about 15 and a half,
- chronological age becomes irrelevant
- and the score is not modified by age.
-
- Scores loosely follow the so-called
- normal distribution which forms a
- graph approximately shaped like an
- inverted U. When all the results of
- a group of individuals are taken
- into account, most will have scores
- around the mean while there will be
- fewer and fewer people scoring at
- the lower and upper bounds.
-
- Last century, there was a school of
- thought which held that a person's
- `intelligence' could be measured by
- the size of a persons brain.
- Ironically, one of the chief fans
- of phrenology turned out to have quite
- a small brain when his skull was
- examined after death.
-
- Around the turn of the century a
- Frenchman by the name of Binet
- developed tests which were aimed at
- identifying schoolchildren who would
- likely to have trouble with academic
- type thinking and may need remedial
- assistance.
-
- These tests were altered and made
- considerably more competitive, by
- pupporting to quantify
- `intelligence' and place all
- individuals on a scale, with the
- highest scoring being the most
- intelligent and the lowest scoring
- the least. The modified forms of the
- original tests became known as the
- Stanford-Binet (After Stanford
- University in California).
-
- This test became the standard and
- even today, tests are standardized
- (modified to match with) with the
- Stanford-Binet.
-
- The way these particular tests are
- scored is based on comparing the
- scores of a number of individuals
- with their scores on an official
- IQ test and also by estimating the
- relative difficulty of the questions
- and the time allowed for them with
- tests in a few books on popular
- psychology.
-
- I cannot guarantee a 100%
- correlation with the Standford-Binet
- or statisticly viable tests unless
- I have the results of thousands of
- people from all walks of life.
-
- With a bit of luck, initial scores
- at least, should not be too
- different from what you would score
- on a standard test (but no
- guarantee!).
-
- The first instances of mass testing
- occurred during the recruitment of
- U.S. soldiers in the first world
- war. What tasks a soldier was given
- to perform, and which soldiers were
- to be trained as officers, were
- determined by results in these
- tests.
-
- Mass testing spread to schools etc.
- In Britain the Eleven-plus tests
- were devised, which were used to
- determine whether children entered
- grammar school, high school or
- technical shool. In Australia
- similar `streaming' has been
- widely used.
-
- It was hoped by some, that an IQ
- score would be a good indication of
- a person's current or potential
- social standing. Though there is
- some correlation with the type of
- occupation, it is amusing to note
- that in one study, derelicts and
- tramps, who were expected to rank
- at the bottom, averaged better than
- policemen, firemen and salesgirls.
- In some instances, people who had
- been placed in institutions, scored
- better than the average university
- student. Ironically, a system which
- some people expected to rank
- people according to their social
- status and breeding, turned out to
- be an equalizer in this instance.
-
- For a large part of this century, it
- Several decades ago there were some
- half baked theories being thrown
- around that performance on these
- of tests was relatively fixed and
- did not change significantly during
- a lifetime. This was supposed to be
- because they tested some kind of
- "innate intelligence" which was
- fixed by your genes.
-
- Middle class people with
- enriched intellecual environments
- tend to do better on these kinds of
- tests. For example, a correlation
- between IQ scores and the number of
- books in a household has been found.
-
- Because of this,there have been some
- attempts at using so called `culture
- fair' tests, in which verbal items
- were tended to be replaced with
- non-verbal ones.
-
- I believe that tests of any sort are
- a test of an acquired skill and that
- different thinking skills can be
- acquired the same as anything else.
-
- It is presumed that you have basic
- numeracy and literacy. If you don't
- this may be a handicap in the
- quizzes.
-
- I have tried to only use commonly
- used (high frequency) words in the
- tests, particuarly in the verbal
- tests wich can easily become a
- straight vocabuarly test. Ideally,
- these should test how clearly you
- can think, not how much you know.
-
- Other basic skills, which would have
- been acquired by most people with
- even an only elementary standard of
- education are presumed.
-
- Assets such as a wide vocabuarly and
- a good general knowledge are NOT
- necessary to obtain good scores in
- these tests. More important are
- speed, accuracy, concentration and
- imagination.
-
- Remember you are trying to maximize
- your score. Try and give the answer
- that is expected rather than try
- to find obscure alternative answers.
- No doubt on some questions there may
- be the possibility that an unusual
- alternative answer exists, but this
- is hardly your objective.
-
- Here is your chance to have a fling
- at some puzzles resembling these
- tests for your own enjoyment.
- Hopefully, you will find that
- practice will greatly improve your
- scores and the idea of an aptitude
- score being fixed can be debunked.
-
- Questions are randomly picked, and
- in some cases randomly created so
- the tests are different each time
- and can be done again and again.
-
- In this version of the program there
- are over 300 questions are in the
- complete version(recieved after you
- have paid your shareware
- contribution) there are over 600.
-
- Have fun and good luck!
