Can we become smarter? Fluid Intelligence (Gf) is the ability to reason and solve new problems independently with respect to previously acquired knowledge. Gf is important for a wide range of cognitive tasks and is considered one of the most important factors in learning. There is a long history of research demonstrating improved Gf when trained. Furthermore, research has shown that the increase in intelligence depends on the amount of training: the more training, the greater the increase in Gf. Therefore, according to some studies, it is possible to improve fluid intelligence. However, other scientists insist that it is extremely difficult for people to move beyond a certain level of reasoning and improve their intellectual functioning. This goes hand in hand with the idea of ​​fluid intelligence as a trait with a strong hereditary factor that is resistant to training. The purpose of this article is to provide a brief overview of studies that have shown improved intelligence after certain interventions. The studies reviewed are divided into several groups: studies that used approaches focused on working memory (WM) training and studies that involved other approaches, as well as research that goes against increasing intelligence. Introduction The definition of intelligence has been a major source of debate. It seems that there are as many definitions of intelligence as there are individuals called upon to define the concept. One possible definition is that “general intelligence is actually a conglomerate of perhaps 100 abilities that work together in various ways in different people to bring out different intelligences” (Plucker 2007). This theory of general intelligence was originally identified by Raymond Cattell and eventually...... half of the article...... Jaeggi, Martin Buschkuehl, John Jonides and Walter J.
