Measuring behaviour Flashcards
What are informal ways of measuring behaviour?
Retrospectively through memory
What are the two ways of formally recording behaviour?
Continuous recording and interval recording
What is continuous recording?
Recording each and every occurrence of a target behaviour within a given period
What is interval recording?
Recording whether a behaviour occurs during each of a series of short intervals within an observation period
What is inter observer reliability?
A measure of the degree of agreement in data tallies made by two or more observers
How many people should rate behaviour?
Two or more
What are acceptable reliability scores in measuring behaviour?
90, anything below 80 would be seen as unreliable.
How can you improve inter observer reliability?
Incresae the observer’s idea of what teh target behaviour is
What is a simple frequency graph?
A graph in which each data point indicates the number of times a behaviour occurred over a period of time
What is a cumulative frequency graph?
A graph in which each data point indicates the total number of times the behaviour has occurred up to that point in time
What method is used to evaluate an intervnetion in behavioural analysis?
Single case experimental designs (SCEDs)
What do SCEDs look at?
Practical significance not statistical significance
What is the definition of a SCED?
A research design in which the behaviour of an individual is compared under experimental and control conditions
What is a basline in SCED research?
A period during which the behaviour under study is recorded, but no attempt is made to modify it
What are the three types of SCEDs?
- ABAB reversal design
- Multiple baseline design
- Alternating treatment design
