Answer:
Jake has gotten much quicker at creating databases after taking an online course.
Explanation:
Cognitive development can be defined as the development of thought processes, skills, knowledge and problem-solving abilities from infancy through adulthood.
Jean Piaget was a developmental biologist and psychologist who worked extensively on cognitive development in infants and teenagers; these are judgement, knowledge and thoughts.
Jean Piaget's stages of cognitive development in an ascending order are;
I. Sensorimotor: this is between 0 - 2 years (18 - 24 months) where the child exhibits object permanence.
II. Preoperational: this is age 2 - 7 years where the child acts in an egocentric manner.
III. Concrete operational: this is age 7 through age 11 and the child thinks logically at this stage.
IV. Formal operational: this is from adolescence (11 years) through adulthood and focuses on logically thinking about abstractions.
Simply stated, ability can be defined as the capacity (skill and competence) of an individual to perform a task.
The scenario which best demonstrates a person's ability is that, Jake has gotten much quicker at creating databases after taking an online course.
