In the operant conditioning paradigm, extinction refers to the process of no longer providing the reinforcement that has been maintaining a behavior. Operant extinction differs from forgetting in that the latter refers to a decrease in the strength of a behavior over time when it has not been emitted.
Gel medium is an acrylic product. It comes in Heavy, Soft, and Regular and has a variety of finishes, Matte, Gloss and Semi-gloss. The basic use for these is to build texture in paintings by mixing them with acrylic paint. If you add a small bit of it to your paint it will also extend the drying time. The Soft gel is the medium that is most often used by paper artists. It can be used as a glue for collage and it is also used to make photocopy transfers.
As I mentioned before, if you want a matte finish, it is best to use matte medium only at the end of your project. I do like Claudine Hellmuthâs Studio gloss and matte âmulti mediums.â They are soft and creamy. I also really like Golden Artist Color gel mediums and other acrylic mediums, like polymer medium.And I like Liquitex gel mediums, glazing mediums, and airbrush mediums. If you want to use gel medium as a glue, a soft gel medium is recommended.el medium used as glue is archival and has a durable, water resistant, UV resistant surface. You can use gel medium as a glue with any type of surface that is suitable for water-based acrylics.
