To examine whether or not children's cognitive development occurs in stages, Professor Blue observes four groups of children. Each child's performance on cognitive tasks is observed two or more times over a period of 2 years. Which group is MOST likely to lead Professor Blue to conclude that development occurs continuously?
A) group A, whose performance on a single task is observed twice each year
B) group B, whose performance on multiple tasks is observed twice each year
C) group C, whose performance on a single task is observed every week
D) group D, whose performance on multiple tasks is observed every week

Quizplus · Accepted Answer

Group D is the most likely to lead Professor Blue to conclude that development occurs continuously because their performance on multiple tasks is observed every week, allowing for more frequent and continuous observation of their cognitive development over time. This frequent observation reduces the likelihood of missing important developmental changes that may occur in a shorter time frame. Groups A, B, and C are all observed less frequently, which may make it harder to detect continuous development over time.
