Final answer:
Continuity theories of development do not claim that development occurs solely as a result of biological processes; rather, they consider development to be a cumulative process that includes cognitive and psychosocial growth alongside biological factors.
Step-by-step explanation:
Psychologists who support continuity theories of development would likely argue that development is a progressive and gradual process rather than one that relies solely on biological processes. The statement that development occurs as a result of biological processes aligns more with nature aspects of the nature versus nurture debate, while continuity theories emphasize that development is a cumulative process that involves gradually improving on existing skills. This approach to development does not exclude biological processes, but it is not limited to them; it also encompasses cognitive and psychosocial growth, acknowledging that learning, memory, language, reasoning, and social relationships contribute to development as well.
