Here, we use a previously validated questionnaire [ 17, 18] in order to test the hypothesis that AMD is associated with fear of falling.
Our hypothesis was that a positive history of falls, slower gait speed, and impaired balance would predict future falls in older cancer survivors.
(Note: Although we refer to both of these hypotheses as falling under a "core deficit", other authors have termed the latter hypothesis the "access deficit" hypothesis [ 36].) According to the triple-code model of numerical cognition [ 58, 59], numbers are represented in three primary codes: visual (Arabic digits), verbal (number words), and analog (magnitude representation).
Among these alternatives, two quickly gained traction: the role of obstetrical complications and the infectious hypothesis, falling in line with a neurodevelopmental model of schizophrenia.
But in recent years, the Sapir-Whorf hypothesis has fallen out of favor as scholars have come under the sway of new approaches stressing the universal aspects of language and cognition.
The insular dwarfism hypothesis had fallen out of favor recently, however, because many researchers thought that the Hobbit's brain, often estimated at 400 cubic centimeters in volume, was too small to have evolved from the larger H. erectus brain, which was at least twice as big.
Although Hypsilophodontidae was interpreted as a natural group in the early 1990s, this hypothesis has fallen out of favor and Hypsilophodontidae has been found to be an unnatural family composed of a variety of animals more or less closely related to Iguanodontia (paraphyly), with various small clades of closely related taxa.
The biological mechanism underlying these shifts has been a matter of debate, with hypotheses falling into two camps: (1) the shift is driven by changes in host abundance, or (2) the shift is driven by seasonal changes in the foraging behavior of mosquitoes.
