Operational definitions
function
defines changes in the environment
topography
defines the form of the behavior
- use when you cannot access functional outcomes, behavior does not produce outcome
Importance of Operational Definitions
so everyone knows what the behavior looks like
- so everyone is on same page on intervention
can all measure the behavior the same
can properly treat behavior
write them out to determine loop holes: isn’t set in stone, should be shifting as intervention continues
allow at least two ppl to evaluate to ensure clarity
observe several times to ensure definition indeed captures behavior
Functions of Behavior
entire purpose is finding a function
behavioral consequences
payoffs: attention, avoidance, control, escape, communication, isolation, anger-release, stimulation
costs: reprimands, instructions, loss of privileges, ignoring, time-out
access to social attention
ex: child starts screaming, the consequence is social attention
access to tangibles or preferred activities
ex: child throwing tantrum, results in access to candy, toy, etc.
escape, delay, reduction or avoidance of tasks
ex: child banging head on desk to escape, delay, reduce, avoid task or demand such as homework or laundry, delay reading activity or chores
automatic
regardless of environment variables, the behavior is occurring
ex: stereotypy behavior- hand flapping, no demands present, preferred activities and such are all available.
whether in an enriched or barren environment it occurs
additional functions
additional
- synthesized: behavior occurring due to several functions. things together in environment
FBA
functional behavior assessment: behavior analyst determine the function of behavior
Second hand observation
indirect measures, live interviews, assessment forms
- getting info from others that have first hand knowledge
first hand observation
descriptive assessment, antecedent-behavior-consequence (ABC) data
Main components of FBA
Why FBAs?
Indirect methods
second hand methods: used to gain info from others who do have first hand experience from behavior 3 components: what we do what we say what we observe
Questions on setting events
- greg hanley question: if i gave you one million dollars how could you get the behavior to occur/behavior not to occur?
