Running head: BENCHMARK- ARTICLE REVIEW Benchmark- Article Review Elizabeth Cerda Grand Canyon University: PSY 402 December 8, 2019 1
BENCHMARK- ARTICLE REVIEW Benchmark- Article Review In 1971 a psychologist by the name of Raymond Cattell first proposed the theory of fluid and crystallized intelligence and its importance on working memory and problem solving (Harvard University, 2019). Both types of intelligence posits two distinct types of intellectual abilities. Crystallized intelligence involves the accumulation of facts, knowledge, and skills which are acquired throughout life through lessons and 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 (Zaval et al., 2015). Fluid intelligence typically declines once late adulthood is reached (Zaval et al., 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. The purpose of this paper is to review the article, Complementary Cognitive Capabilities, Economic Decision Making, and Aging (Li, Baldassi, Johnson & Weber, 2013), in attempts to discuss major findings within the study and address the strengths and weaknesses presented. Major Findings & Conclusions In the article, Complementary Cognitive Capabilities, Economic Decision Making, and Aging (Li et al., 2013), researchers hypothesized that older adults with higher levels of crystallized intelligence can offer an alternative path to good decisions when the fluid intelligence pathway declines as they get older. To accomplish this, participants were evaluated in three different sections: decision traits, temporal discounting and financial literacy. This study revealed several major findings that support the proposed hypothesis. The first major finding was found in the decision trait section, which showed that older adults who had lower levels of fluid 2
