CLASS EXPERIMENT
1

 Close your eyes and imagine that insects are crawling on you skin
2

 Close your eyes and imagine the insects are present. (not touching you)
3

 Speculate as to the reason why we did this experiment.
4

 What role did the student observers play in this experiment?

OBSERVATIONS
(PAGE 24 PORTFOLIO)

Time Sampling
 A technique in which the observer defines several target behaviors, divides the observation period into short intervals, and then alternates from observing to recording every other interval.

Event Sampling
 The observer defines a target behavior and records every instance of that behavior as it occurs throughout the observation period.

Narrative Recording
 A running description of behavior in which everything that is said or done during the observation period is recorded.

Time Sampling
 I will play the video one minute at a time.
After a minute I will pause the video and you will write down your observation in the chart.
I will repeat this process for the duration of the 10 minute video.





Jumping - a form of locomotion or movement in which an organism propels itself through the air.
Running - traveling on foot at a fast pace.
Grooming - to clean and maintain the appearance.
Display – puffs up chest, makes body seem bigger, in effort to show off.
Aggression – hitting, pushing, fighting (not playing)
Submission – running from or obviously avoiding contact with another individual.

Post Observation
 Individually tally the number of intervals in which each behavior occurred. Then, answer the following questions:
 Which behavior occurred most often?
 Which behavior occurred least often?
 Are there any behaviors that seem to always, or almost always, occurring during the same intervals?

Post Observation
 Pair up with another student and compare your answers to the preceding questions.
 Did you disagree on any of the previous questions? If so, which one(s)? Why did you disagree?

Final Question


What are the strengths and weaknesses of observations as a method of research.
If you could change anything about the previous observation, what would it be?
