2 Running head: BENCHMARK – ARTICLE REVIEW Intelligence is broken down into two sub categories; fluid and crystallized intelligence. Crystallized intelligence has everything to do with the accumulation of facts, knowledge, and skills which we gain through a lifetime of experiences (Gazzaniga, Ivry & Mangun, 2018). As an individual ages and reaches late adulthood, crystallized intelligence increases due to us going through more experiences for us to gain knowledge from (Zaval, Li, Johnson & Weber, 2015) On the other hand fluid intelligence is our ability to think logically and solve our problems in novel situations. Fluid intelligence is also, entirely independent of obtained knowledge that we have learned over time. Contrary to what is known about crystallized intelligence, fluid intelligence typically declines once late adulthood is reached (Zaval, Li, Johnson & Weber, 2015). As a person ages, these two subdivisions of intelligence can be greatly affected, which can cause impairments in life, such as difficulties in decision-making. These impairments in those executive functions greatly affect the fluid intelligence and fluid intelligence also has an effect on those impairments. The purpose of this paper is to review the article, The Relationship Between Executive Functions and Fluid Intelligence in Parkinson’s Disease (Roca et al., 2012) address its major findings, and go over strengths and weaknesses. In the article, “ The Relationship Between Executive Functions and Fluid Intelligence in Parkinson’s Disease ” a study was performed showing how the decline of fluid intelligence can have disastrous affects in the frontal lobe deficits in Parkinson’s disease patients” (Roca et al.,
