Midterm Flashcards
Event sampling definition:
The observer waits for and records a specific preselected behavior.
What is ES used for?
to study the conditions under which behaviors occur OR the frequency of behaviors
Advantages of ES:
- Can be used to study infrequent behaviors
- Notes behaviors each time they occur
- Notes the preceding circumstances
- Notes the consequences of the behavior
Disadvantages of ES:
- Focuses on only one or a few behaviors
2. Does not have as much detail as running record or anecdotal record
Guidelines for ES:
- Clearly identify and operationally define the behavior that you want to study.
- Know enough about the behavior in general that you know where and when to observe
- Determine what kind of information you want to record
- Make your recording sheet as easy to use as possible
Time Sampling definition:
To observe specified behavior of an individual or group, and record the presence or absence of this behavior during short time intervals of uniform length.
Advantages of TS:
1) Takes less time than running record and anecdotal records
2) Can record data on many children at once
3) It provides useful information about the intervals or
frequency of behavior
4) Counts of behavior can be used for research purposes
Disadvantages of TS:
1) May miss important behaviors
2) Context of behavior not noted: does not focus on the causes and consequences of the behavior
3) It is limited to behaviors that occur frequently and not rare behaviors that might also be important
Developing a TS Schedule
Sampling of children’s behavior can be done in a number of ways:
1) Use a check to indicate whether a behavior occurred
2) Tally the number of times a behavior occurs
Guidelines for TS:
1) It is appropriate only for behaviors that occur fairly frequently- once every fifteen minutes on the average
2) It should be used only for behaviors that are easily observable
Operational Definition:
assigns meaning to a construct or a variable by specifying the activities or “operations” necessary to measure it
Checklist:
List  of specific traits or behaviors arranged in logical order.
What is a checklist useful for?
Types of behavior or traits that can be easily and clearly specified.
(Info from anecdotal and running records can be transferred to checklists to make interpretations)
Advantages to checklists:
1) Used to condense info. from RR or Anecdotal
2) Helps to focus observation on many behaviors at once
3) Little Training Required
4) Easy to use
Disadvantages to checklists:
1) Not very detailed
2) Little info. regarding context or sequence of events
3) May miss important information not on checklist
4) Notes if a behavior occurred, but not how often or duration
