Final answer:
The general motor ability hypothesis is an outdated view that suggested a single ability was the foundation for all motor behavior, which is now replaced by more nuanced theories acknowledging the complex factors influencing motor skill development.
Step-by-step explanation:
The concept in question pertaining to motor skills and their development is known as the general motor ability hypothesis. This early theory posited the idea that there was a single global ability underlying all motor behavior. However, it has since been viewed as incorrect, with more comprehensive models like the Cattell-Horn-Carroll (CHC) theory illustrating that cognitive abilities, including motor skills, are organized into a hierarchy of general, broad, and narrow abilities, with motor skills such as newborn reflexes and the development of fine and gross motor abilities falling into the narrow spectrum. Moreover, the understanding of how motor skills develop has evolved, recognizing that factors such as nature, genes, biology, and individual experiences including cultural differences can affect the sequence and pace of motor development. This illustrates a shift towards the recognition of a more complex interplay of multiple factors influencing motor abilities rather than a single global motor ability.
