Part I: General Cognitive Changes

Emerging Adulthood through Early Adulthood (approx. 17-25)

1. Prefrontal Cortex Maturation: During this period, the prefrontal cortex, responsible for higher-order functions such as reasoning, judgment, and problem-solving, continues to develop (Steinberg, 2014). This maturation can lead to improved decision-making skills and greater emotional self-regulation as individuals learn from their experiences.
2. Increased Cognitive Flexibility: Emerging adults often exhibit an increase in cognitive flexibility, which is the ability to adapt one's thinking and behavior to new, changing, or unexpected situations (Kuhn & Pease, 2006). This adaptability is important for navigating complex societal demands and relationships.
3. Memory Consolidation: Research indicates that memory processes, particularly encoding and consolidation, are optimized during early adulthood (Reisberg & Heuer, 2008). This allows for the efficient storage and retrieval of information, resulting in improved academic and professional performance.

Early Adulthood Through Middle Adulthood (approx. 25-45)

1. Sustained Attentional Control: Individuals in early to middle adulthood generally show sustained improvements in attentional control compared to their younger counterparts (Madden & Costello, 2015). This ability to maintain focus can enhance productivity in both personal and professional domains.
2. Executive Functioning Development: The development of executive functions—such as working memory, cognitive flexibility, and inhibitory control—continues into middle adulthood (Chevalier et al., 2020). Adults at this stage often display better planning and organizational skills, which contribute to their success in managing long-term projects.
3. Neurotransmitter Changes: Neurotransmission changes, particularly involving dopamine and serotonin, may occur, leading to altered motivation and mood regulation. These changes can affect cognitive performance, motivation, and emotional stability (Cools et al., 2008).

Middle Adulthood through Late Adulthood (approx. 45 through death)

1. Decline in Processing Speed: Cognitive processing speed generally begins to decline in middle adulthood and continues into late adulthood (Salthouse, 2010). This decline can affect task performance, particularly in complex or time-sensitive situations.
2. Working Memory Changes: Research shows a decrease in working memory capacity during middle to late adulthood, which can impact the ability to hold and manipulate information over short periods (Salthouse et al., 2014). This can affect daily tasks that require multitasking.
3. Memory Variability: While some types of memory (e.g., semantic memory, which involves facts and knowledge) remain relatively stable or even improve, episodic memory (personal experiences) typically declines with age (Schaefer et al., 2019). This shift can affect individuals' recounting of personal experiences and forming new memories.

Part II: Follow-up Questions

1. During what age range do we see the most dramatic cognitive changes occurring?
The most dramatic cognitive changes occur during emerging adulthood (approximately ages 17-25). This is when significant developments in the brain, particularly the prefrontal cortex, affect decision-making, judgment, and emotional control. Additionally, cognitive abilities, such as problem-solving and memory consolidation, continue to evolve markedly during this period (Steinberg, 2014).
2. Choose (and explain how) at least two factors that might exacerbate the cognitive changes above.
* Lack of Sleep: Insufficient sleep can exacerbate cognitive decline, negatively impacting attention, learning, and memory processes (Hirshkowitz et al., 2015). Sleep deprivation may lead to reduced cognitive flexibility and impaired judgment, particularly in emerging adults who often have demanding schedules.
* Chronic Stress: Prolonged stress has been shown to lead to cognitive deficits, particularly in working memory and decision-making abilities, exacerbating age-related declines seen in late adulthood (McEwen, 2017). Stress can impact neuroplasticity and lead to functional impairments in the prefrontal cortex.
3. What can be done to offset some of these cognitive changes?
To offset declines in processing speed observed in late adulthood, cognitive training programs that emphasize memory exercises and problem-solving strategies can be beneficial (Ball et al., 2002). Additionally, accommodating strategies such as using reminders, prioritizing tasks, and minimizing multitasking can help maintain cognitive function in elderly individuals.
4. What was your biggest take-away from this activity? What changes might you make now?
The most profound realization from this activity is the importance of maintaining cognitive health throughout adulthood. Some changes I might implement now include prioritizing sleep hygiene to combat cognitive decline, engaging in regular physical exercise to promote overall brain health, and seeking ongoing opportunities for mental challenge through learning new skills or hobbies.
