2.2 Intelligence as a subset of creativity
In this relationship model，intelligence is a key component in the development of creativity.Theories of creativity include intelligence as a subset of creativity.
Sternberg ＆Lubart's Investment Theory.Using the metaphor of a stock market，they demonstrate that creative thinkers are like good investors—they buy low and sell high（in their ideas）.Like under／low-valued stock，creative individuals generate unique ideas that are initially rejected by other people.The creative individual has to persevere，and convince the others of the ideas value.After convincing the others，and thus increasing the ideas value，the creative individual“sells high”by leaving the idea with the other people，and moves onto generating another idea.According to this theory，six distinct，but related elements contribute to successful creativity：intelligence，knowledge，thinking styles，personality，motivation，and environment.Intelligence is just one of the six factors that can either solely，or in conjunction with the other five factors，generate creative thoughts.
Amabile's Componential Model of Creativity.In this model，there are 3 within-individual components needed for creativitydomain-relevant skills，creativity-relevant processes，and task motivation—and 1 component external to the individual：their surrounding social environment.Creativity requires a confluence of all components.High creativity will result when an individual is：intrinsically motivated，possesses both a high level of domainrelevant skills and has high skills in creative thinking，and is working in a highly creative environment.
Amusement Park Theoretical Model.In this 4-step theory，both domain-specific and generalist views are integrated into a model of creativity.The researchers make use of the metaphor of the amusement park to demonstrate that within each of these creative levels，intelligence plays a key role.
To get into the amusement park，there are initial requirements.Initial requirements are necessary，but not sufficient for creativity.They are more like prerequisites for creativity，and if an individual does not possess the basic level of the initial requirement（intelligence），then they will not be able to generate creative thoughts／behaviour.
Secondly are the subcomponents—general thematic areas—that increase in specificity.Like choosing which type of amusement park to visit，these areas relate to the areas in which someone could be creative.Thirdly，there are specific domains.After choosing the type of park to visit e.g.waterpark，you then have to choose which specific park to go to.Within the poetry domain，there are many different types that have to be selected from.
Lastly，there are micro-domains.These are the specific tasks that reside within each domain e.g.individual lines in a free verse poem／individual rides at the waterpark.
