Chapter 21 – Direct Behavioural Assessment: What to Record and How
Characteristics of Behaviour to be Recorded
Topography of Behaviour – specific movements involved in making the response
Amount of Behaviour
Frequency of Behaviour: # of instances of behaviour in a given period of time
Frequency graph: # of instances recorded within a given period of time
Cumulative graph: each response is cumulated to total responses of all previous sessions (therefore, the graph
does not ever decrease, if no instances occur, then it is a flat line)  figure 21.4
oPreferred over frequency graph when comparing 2 or more behaviours when differences are small
Relative Duration of Behaviour
oRelative duration = Duration divided by total time
oRelative duration of behaviour  length of time that the behaviour occurs within some period
oGood for behaviours that are hard to count (e.g. temper tantrums)
oUse timers/stopwatches/clocks
Intensity of Behaviour: Magnitude/force of behaviour
Stimulus of Control of Behaviour
Assess behaviours under conditions which behaviours most likely to occur
Stimulus control  correlation b/w a stimulus and response
Assessment of Basic Learning Ability Revised (ABLA-R)  assesses the person w/ intellectual disabilities to learn
oLevel 1: Imitation  copy the examiner
oLevel 2: Position discrimination  keep placing object in the container to the left
oLevel 3: visual discrimination  place objects in the yellow can
oLevel 4: visual identity match-to-sample discrimination: place yellow cylinder in yellow can; place red
cube in red box
oLevel 5: visual non-identity match-to-sample discrimination  presented w/ purple wood shaped the
word “Can” or “Box” and must place “can” in yellow can or “box” in red box
oLevel 6: auditory-visual combined discrimination  put the object in the container when examiner says
“red box” or “yellow can”
In ABLA-R, correct responses are reinforced and incorrect responses are followed by error-correction procedure

Client only passes ABLA-R in a level when client makes 8 consecutive responses
Latency of Behaviour – time b/w occurrence of stimulus and beginning of behaviour (reaction time)
Quality of Behaviour
Quality is not a characteristic of behaviour, but it is a refinement
Quality is arbitrary designation of characteristics of behaviour that has some functional or social value
