10. What is one scientific result that invalidates the common myth of cramming?
Answer: D
Intense studying releases stress hormones like cortisol
Cramming can lead to intense studying, which has been shown to cause the release of stress hormones such as cortisol. This physiological response can hinder cognitive functions and impede effective learning, thereby invalidating the myth that cramming is an effective study method.
A) Short-term memorization fails with prolonged study sessions
While it is true that short-term memorization may not be effective, this option does not directly address the specific physiological effects of cramming. It fails to highlight how the stress response associated with cramming negatively impacts retention and performance.
B) The brain is limited in its ability to adapt in response to experiences
This statement is overly broad and does not specifically pertain to the effects of cramming. It incorrectly suggests a general limitation of the brain rather than focusing on the negative outcomes associated with intense study sessions and the stress they induce.
C) A negative feedback loop is initiated with heavy memorization
Although heavy memorization can create stress, the concept of a negative feedback loop is not clearly articulated here. This option lacks the specific connection to the release of stress hormones, which is crucial in understanding the adverse effects of cramming.
D) Intense studying releases stress hormones like cortisol
This option accurately identifies a significant scientific result that invalidates the myth of cramming. The release of cortisol during intense studying clearly demonstrates how cramming can negatively affect cognitive processes, making it a detrimental study strategy.
Conclusion
Option D is definitively correct as it directly links the physiological effects of cramming to the release of stress hormones like cortisol, which impairs learning and memory retention. All other options either misrepresent the effects of cramming or fail to connect with the critical physiological responses that invalidate the effectiveness of this study method.
