Hi!
According to John Horn, fluid intellugence steadily declines from middle adulthood onward.
Historians use a standard shorthand, “Gold, God, and Glory,” to describe the motives generating the overseas exploration, expansion, and conquests that allowed various European countries to rise to world power between 1400 and 1750. “Gold” refers to the search for material gain through acquiring and selling Asian spices, African slaves, American metals, and other resources. As merchants gained influence in late-medieval western Europe, they convinced their governments to establish a direct connection to the lucrative Asian trade, leading to the first European voyages of discovery in the 1400s. “God” refers to the militant crusading and missionary traditions of Christianity, characterized in part by rivalry with Islam and hatred of non-Christian religions. “Glory” alludes to the competition between monarchies. Some kings sought to establish their claims to newly contacted territories so as to strengthen their position in European politics and increase their power at the expense of the landowning nobility. They also embraced the ideology of mercantilism, which held that governments and large private companies should cooperate to increase the state’s wealth by increasing the reserves of precious metals. Motivated by these three aims, several western European peoples gained control or influence over widening segments of the globe during the Early Modern Era. By 1914 Europeans dominated much of the world politically and economically. Hope this helps!
I believe the answer is: testing effects
Testing effects refers to the perception long term memories tend to be increased when our brain is dedicated to retrieving a certain type of information over and over again. When studying, this tend to make people become bias and overconfident after repeating a certain topic, making them believe that they do not need to study the topic again before test.
