Effect of Block Technique
Block Technique is one of the art therapy methods and clients express anything they desire by using LEGO® blocks on the plate. It was developed based on the theory of sandplay therapy. The main theoretical feature is constructing anything we like using ready-made objects in the secure framework. It has therapeutic effects to us and I examine its effects by using statistical methods.

Example of Expression

Our clients express their inner unconscious image by using toy blocks on the plate.
The plate has an important role as a secure framework and this structure holds clients' expression safety.
We therapists also watch over and protect their expression process and interpret the meaning of it.
This process is quite therapeutic and Block Technique is useful for art therapy.
Many kind of psychological factors such as personality are projected into their expression.
Therefore, Block Technique is useful as a projective method for a psychological assessment.
It is also available in the group situation.
Studies shows some positive effect on the group work using block technique.
For example, social skills are facilitated through collaborative block creation with others.
