Chapter 5 Ledford Flashcards
dimensions of behavior
time and number
reversible behaviors
likely to revert to baseline levels if an intervention is removed
non-reversible behaviors
changes are not permanent but are likely to maintain in the absence of an intervention
variables to consider when selecting a recording procedure
- target behavior
- objective of intervention
- practical constraints of the setting behavior will be measured
- sensitivity to document behavior change
direct, systematic observation and recording (DSOR)
- most common dependent variable assessment
- continuous and non-continuous recording
free-operant events
events that re free to occur at any time
trial-based events
have specific antecedent conditions
Partial interval recording
- most widely used interval system
- suggested when
- feasible to use small interval lengths
- behavior has short duration
- dimension of interest is count
- it is reported as an estimated count rather than percentage of intervals
whole interval recording
least widely use interval system
construct validity
- whether measurement procedures accurately reflect the concept interested in measuring
blind observers
data collectors who do not know the condition in effect for the data they are collecting
discrepancy discussion
a discussion about any difference between observers where a consensus is agreed to
occurrence agreement formula
(# agreements for occurrence trials/# agreements for OT + # of disagreements for OT) x100
Non-occurrence agreement formula
(# agreements for non-occurrence trials/# agreements for no + # disagreements for not) x100
agreement formula
(# agreements within time window/# agreements + #disagreements) x100
