Benchmark- Article Review Raymond Cattell was a psychologist who first projected the theory of fluid and crystallized intelligence and its significance on working memory and critical thinking (Harvard University, 2019). Both types of intelligence suggest that there are two distinct types of intellectual abilities, known as crystallized intelligence and fluid intelligence. Crystallized intelligence is known as the accumulation of knowledge, skills, and facts which are often times acquired throughout life by life lessons and life experiences. As an individual ages, crystallized intelligence increases (Zaval, Li, Johnson & Weber, 2015). On the contrary, fluid intelligence is the capacity to think logically and problem solve in novel situations and is entirely independent of obtained knowledge. Fluid intelligence typically declines once late adulthood is reached (Zaval et al., 2015). As a person ages, these two pieces of a humans’ intelligence can be greatly affected. This eventually can cause deficiencies in life, including having a difficult time making decisions. This paper is being written to review the article, Complementary Cognitive Capabilities, Economic Decision Making, and Aging (Li, Baldassi, Johnson & Weber, 2013), in efforts to examine significant discoveries inside the investigation and address the qualities and shortcomings introduced. Major Findings and Conclusions In the article Complementary Cognitive Capabilities, Economic Decision Making, and Aging (Li et al., 2013), analysts conjectured that adults who are more seasoned in age have more elevated levels of crystallized intelligence, and accordingly they can offer an elective way to making better choices as the fluid intelligence pathway will diminish as they grow older in age. To achieve this, members were assessed in various areas. These three areas are: financial literacy, temporal discounting and decision traits. This examination uncovered a few significant 2
discoveries that help the proposed theory. The most significant finding was that in the decision trait section, which presented that more established adults who had lower levels of fluid intelligence reflected lower choice execution, yet those adults who had elevated levels of crystallized intelligence helped balance the negative age effects in a specific way.
