1 Of the nine faces shown (or 18 half-faces), six out of 18 half-faces

are shaded. One-third of the total figure visible is therefore

shaded.

The value of the circle shown in the middle is 360. The value of

each segment is therefore 45 (360 Ä 8); the remaining angles,

therefore, are equal to 180 À 45 = 135 or 67.5 each (180 being

the sum of the internal angles of a triangle); each internal angle is

therefore 135.

9 You have drunk exactly the same amount of coffee as you have

drunk milk. The cup originally contained coffee only; you have

poured in one-third þ one-half þ one-sixth, which adds up to 1.

You have therefore poured into the cup exactly the same amount

of milk as the coffee and have, in effect, drunk one full cup of

coffee and one full cup of milk.

bag 3, four balls from bag 4 and five balls from bag 5. Place all 15

balls on the scale. The scale would register 150 Â 20 = 3000 grams

if all balls weighed 20 grams. If the scale registers 2998 grams,

then the balls in bag 1 are light; if the scale registers 2996, the

balls in bag 2 are light; if the scale registers 2994, it is the balls in

bag 3; if the scale registers 2992, it is the balls in bag 4; and if the

Chapter 4 ^ Creativity

Test 4.0

Creativity personality test

Assessment

Total score 90–125

This score indicates a high degree of creativity and means that the right,

creative, side of your brain appears to be extremely active.

People who are creative in nature are likely to have tried out many

different pursuits during their lifetime and will continue to do so in

the coming years, as they are never afraid of trying out something

new. It is even possible that you have already achieved some degree of

success and fulfilment within a creative environment, e.g. as a writer

or designer.

It is suggested that people who have achieved a high score on this

test, but who have not yet experimented with creative pursuits such

as painting, garden or interior design or music, should follow their

intuition and do so now, whatever their age, since they appear to have

the necessary qualities, which possibly have been lying dormant, to

achieve success and fulfilment in some sort of creative pursuit.

While it is difficult to be too creative, people who have scored

highly on this test should not overlook the importance of developing

their analytical and intellectual skills, as well as their creative talents.

Total score 65–89

This score indicates an average degree of creativity.

Although you may exhibit creative tendencies, a score at the lower

end of this group suggests it is possible you may have neither the

time nor the confidence to try out new creative pursuits. In order to

become more creative it may be necessary to develop more confidence

and be more relaxed about taking intellectual risks, such as sitting down

and doing some drawing or painting, or making a start on writing the

novel you always felt was inside you.

K:/Books/1387jw/0470017732/ch07/text_s/c07.3d

Answers, explanations and assessments

A score within the higher range of this group suggests that you

may have already achieved some degree of creative success, but that

you may also have major undeveloped talents waiting to surface and

be cultivated.

Generally, however, any score within this group does suggest you

are in the fortunate position of being able to balance your creative

tendencies with logical and analytically formed judgements in order to

turn many of your ideas into a single, realistic and workable concept.

Total score less than 65

Although this score indicates a lower than average degree of creative

talents there may be many reasons for this, e.g. while you may possess

a rich storehouse of ideas, it may be that you feel more comfortable

when guided by set principles and traditional conventions.

Although each one of us has the potential to be creative in some

way or other, it may be that, like many other people, you have not yet

explored your creative talents.

It is quite likely that your skill outlets have been channelled into

one particular area in order to develop a career, and as such you are a

specialist who has little time to explore other avenues.

Creativity and intellect are two quite separate brain functions and it

is thus entirely possible to be highly intellectual in some fields but not

creative, and vice versa. It is, however, possible to train yourself to

bring out latent creative talents if you have the time and inclination to

do so. By exploring new avenues and learning experiences it is possible

to broaden your horizons considerably, and possibly surprise yourself

by discovering you possess creative talents and aptitudes of which you

were previously unaware.

Test 4.1

Imaginative shapes

Assessment

You can mark this test yourself; however, it is best marked by a friend

or family member. Award one mark for each recognisable sketch,

provided that it is not similar to any of the other sketches. For

example, if you draw a face, a second face scores no points as each

sketch must have an original theme. You thus obtain marks for variety.

If you are creative, you will tend to try to draw something different

for each sketch.

There is no one correct answer to any of the eight sketches as for
