U-shaped development, also known as U-shaped learning, is the typical pattern by which select physical, artistic, and cognitive skills are developed. It is called “U” shape development because of the shape of the letter U in correlation to a graph, skills developed in the “U shaped” fashion begin on a high position on a graph’s Y-axis. The skills start out at a high performance level and over time the skills descend to a lower position on the Y-axis. After another period of time the skill once again ascends to a higher position on the y-axis. A "U" shaped time line is created of the skills development. U-shaped development can be seen in cognitive skills such as learning new words, or doing high levelalgorithms in mathematics. The skill can also be artistic such as painting or playing a musical instrument, and physical skills such a walking and weight lifting.
Artistic skill development
This U-shaped curve is different from the other types of skill development because this skill has an artistic rating with it, which means there could be differences in opinion, but in studies where children, adultartists, and non-artist adults were all given the same directions to draw a self portrait, the children’s and the artists' were the closest of the three to depicting the face when picked by an outside group. In theory, this result is because of an innate “creative skill” in children that is either lost to age with non-artist adults or practiced by adult artists. In artists the Y-axis would be the “creative skill”, and the X-axis would be time, but in non artists the “U” shaped curve would not apply.
Physical skill development
The U-shaped development in physical skill comes from the development and recession of muscular strength, on the graph the Y-axis is muscular strength and the X-axis is time. Muscular strength develops and recedes over time because of necessity; one example of this is a baby learning to walk. The baby will gain the strength in its legs to be able to support itself and walk, but it then grows larger, and the strength in its legs becomes less than required to support itself, but then the baby’s leg strength increases again which gives it the ability to support itself again.
This developmental curve reflects the progression of intuitive thinking processes as a person develops more advanced knowledge structures in a specific area. The shape of the curve reflects the variability of general intuitional availability.This means once intuition levels increase but also s/he can make more higher order intuitive connections/understandings given a corresponding increase in expertise. In this graph the axes would be availability of intuition and level of expertise, instead of the skill level and time. The “U” curve represents two different types of intuition: which are referred to as immature intuition and mature intuition.
“cognitive theory”- Is a learning theory of psychology that explains the behavior of human through thought process. The theory states that humans are logicalbeings, that make the choices that make the most sense to them.
“humanist theory"- Is a theory that the behavior changes based on what education was received by the individual.
There are branch theories that relate to these theories and the theories have different notions on how environmental stimuli change a person, but none dismiss or disprove the U-shaped development theory.
