After reading Modules 37-41, consider how stress and emotions can alter a person’s cognitive abilities. *Remember to use APA formatting, in-text, full reference citations.

Stress and emotions have a profound impact on a person’s cognitive abilities. Research has shown that both acute and chronic stress can impair cognitive functioning, including attention, memory, and decision-making processes (McEwen, 2017). Additionally, emotions can influence cognitive processes such as perception, attention, memory, and problem-solving skills (Damasio, 1999).
One of the ways in which stress affects cognitive abilities is through its impact on attention. When individuals are under stress, their attention becomes narrowed and focused on the stressor itself, often leading to a failure to attend to other important information (Sapolsky, 2015). This narrowing of attention can impede the ability to effectively process and integrate new information and can impair performance on tasks that require divided attention or multitasking.
Stress can also have detrimental effects on memory. The stress hormone cortisol has been shown to impair memory retrieval and consolidation (McEwen, 2017). When individuals are stressed, the release of cortisol can interfere with the function of the hippocampus, a brain region crucial for memory formation and retrieval (Sapolsky, 2015). As a result, high levels of stress can lead to difficulties in remembering and recalling information.
Furthermore, chronic stress has been associated with structural changes in the brain, particularly in the prefrontal cortex, amygdala, and hippocampus (McEwen, 2017). These changes can impact executive functions such as self-regulation, decision-making, and problem-solving. The prefrontal cortex, which is responsible for these higher cognitive functions, can become impaired under chronic stress, leading to difficulties in making rational decisions and effectively solving problems (Mather & Lighthall, 2012).
Emotions, on the other hand, can shape cognitive processes through their influence on perception and attention. For example, studies have shown that positive emotions broaden individuals’ cognitive scope and enhance creativity and problem-solving abilities (Fredrickson, 2001). Positive emotions can increase the flexibility and breadth of attention, allowing individuals to think more broadly and consider multiple perspectives.
On the contrary, negative emotions can have a narrowing effect on attention and cognition. When individuals experience negative emotions such as fear or anxiety, their attention becomes narrowly focused on the potential threats, leading to a reduced ability to attend to and process other information (Eysenck et al., 2007). This narrowing of attention can impair problem-solving abilities and hinder flexible thinking.
The impact of emotions on memory is also well-documented. Emotionally salient events are often better remembered than neutral events, due to the amygdala’s involvement in the encoding and consolidation of emotional memories (McGaugh, 2015). The amygdala, a structure responsible for processing emotional stimuli, influences memory formation and can enhance the strength and vividness of emotional memories.
In conclusion, both stress and emotions have significant effects on a person’s cognitive abilities. Stress can impair attention, memory, and executive functions, while emotions can influence perception, attention, memory, and problem-solving. These findings highlight the importance of considering the emotional and stress-related factors when evaluating cognitive performance and designing interventions to improve cognitive functioning. Further research is needed to explore the underlying mechanisms and develop effective strategies for managing stress and regulating emotions to optimize cognitive abilities.
