Some researchers were interested in studying whether or not Sam and Sally "talk to themselves" as they work on difficult math problems. The researchers shot 20-minute videotapes of Sam and Sally as they worked on math problems when they were in the first grade, third grade, and finally the fifth grade. The 20-minute videos captured __________ development, and a comparison of the first, third, and fifth grade videotapes captured _________ development.

The 20-minute videos captured microgenetic development, as this term refers to the observation of changes over a relatively short amount of time, such as how Sam and Sally's self-talk behavior might change during the course of solving math problems. A comparison of the videos from first, third, and fifth grade captured ontogenetic development, which refers to the development of an individual over time, in this case, observing how their behaviors change as they grow from first to fifth grade.
