Unit 3 EBQ: Impact of Sleep Deprivation on Cognitive and Physical Health
Using the sources provided, develop and justify an argument about the impact of sleep deprivation on cognitive and physical health.
Group 1
Although numerous studies have investigated the relationship between sleep and students’ academic performance, these studies utilized subjective measures of sleep duration and/or quality, typically in the form of self-report surveys; very few to date have used objective measures to quantify sleep duration and quality in students. Our aim in this study was to explore how sleepiness affects university students’ academic performance by objectively and ecologically tracking their sleep throughout an entire semester By collecting quantitative sleep data over the course of the semester on nearly 100 students, we are motivated to relate objective measures of sleep duration, quality, and consistency to academic performance from test to test and overall in the context of a real, large university college course. A secondary aim was to understand gender differences in sleep and academic performance.

The study by Alhola and Polo-Kantola (2007) aimed to investigate the neurophysiological effects of total sleep deprivation (TSD) on cognitive performance in healthy adults. Sleep deprivation is a common issue in modern society, with significant implications for cognitive function and overall health. Previous research has shown that lack of sleep impairs various cognitive domains, including attention, memory, and executive functions. This study sought to elucidate these effects through a controlled experimental design.

Knutson K.L. investigates the potential link between sleep duration and obesity risk. The study is grounded in the growing body of evidence suggesting that modern lifestyle changes, including reduced sleep, may contribute to the obesity epidemic. The primary objective is to explore how insufficient sleep may influence metabolic processes and behaviors that contribute to weight gain.

Question 1a
Propose a specific and defensible claim based in psychological science that responds to the question.
Support your claim using at least one piece of specific and relevant evidence from one of the sources. (i) Explain how the evidence from Part B (i) supports your claim using a psychological perspective, theory, concept, or research finding learned in AP Psychology.
Support your claim using an additional piece of specific and relevant evidence from a different source than the one that was used in Part B (i). (ii) Explain how the evidence from Part C (i) supports your claim using a different psychological perspective, theory, concept, or research finding learned in AP Psychology than the one that was used in Part B (ii).
