Case Study
Summary of Observations
Once you have collected a number of observations, review them and look for patterns. See if you can group the observations and make some general statements summarizing them. For example, a summary might be "the child responds better to a male voice" or "the child responds better inside than outside".
Given the following observations and levels of response, what summaries or generalizations can you make? (Note: some observations have been added.)
- In an average noise environment, when the teacher spoke, the child stopped moving and held still for about 3 seconds before moving again.
Level 2 (Attention / Alerting) - In an above-average noise environment, when the teacher sang along with music with her mouth a few inches from the child's ear, the child stopped moving for the duration of the singing.
Level 2 (Attention / Alerting) - In an above average noise environment, when the teacher sang along about 2 ft from the child's ear, the child did not respond.
NR (No Response) - In a below-average noise environment, when an unfamilar woman spoke to the child from a distance of about 3 ft, she did not respond.
NR (No Response) - In a below-average noise environment, when an unfamiliar woman spoke to the child from about 2 ft, then moved closer to a distance of a few inches, the child did not respond.
NR (No Response) - In a below-average noise environment, when the teacher spoke the child's name from a distance of 2 ft, the child stopped moving and turned her head toward the teacher.
Level 3 (Localization) - In a very noisy environment, when the teacher spoke the child's name from a ditance of 1 ft, the child did not respond.
