A 2007 review by Lupien at al [8] of the effects of stress hormones (glucocorticoids, GC) and human cognition revealed that memory performance vs. circulating levels of glucocorticoids does manifest an upside-down U-shaped curve, and the authors noted the resemblance to the Yerkes–Dodson curve.

[6] Kuznets had two similar explanations for this historical phenomenon: workers migrated from agriculture to industry; and; rural workers moved to urban jobs.

In portraying the U.S. as an innocent victim of an unprovoked communist invasion and occupation of North America, Red Dawn fundamentally inverted the historical reality of U.S. Cold War foreign ...
