Broderick & Blewitt (2015) define fluid intelligence as “basic operational characteristics that seem to directly reflect how well the hardware of the nervous system is working, affecting the efficiency of processes like reasoning.” Crystallized intelligence is defined as “the compilation of skills and information we have acquired in the course of our lives.” In simpler terms, fluid intelligence can be seen as the speed and efficiency of our intellectual processes. Crystallized intelligence is the accumulated knowledge of a person’s lifetime that includes things like languages, skills, and other things that a person has memorized.
As adults age, their level of fluid intelligence seems to decrease, which results in slower and less efficient processing ability. Older adults can also still learn, though it will be a slower and more difficult process due to the decline in working memory. However, older adults tend to be better at solving familiar, every-day problems and memory games than younger adults due to their large crystallized resources (Broderick & Blewitt, 2015).
Professionals could use this information to support positive adjustment for aging adults by providing more relatable examples in training for a new role or being patient when the older adult is learning something new. Additionally, fluid intelligence should be assessed directly for older adults because it cannot be significantly predicted using subjective or objective measure (Shakeel & Goghari, 2017). Since fluid intelligence cannot be predicted, this encourages a case-by-case approach to the training or education of older adults. Interestingly, Cooper et al. (2009) found that moderate alcohol consumption was associated with better cognition in regions of France. However, that study’s results would need further research to eliminate any confounds and expand applicability. If the effect still stands, moderate alcohol intake could be advised to older adults to benefit their cognition.
