Motivating Operations
Motivating operations based on learning history that alter reinforcer effectiveness and evoke/abate behaviors
CMO
When discrimination between the comparison stimuli depends on the sample stimulus present in each trial
conditional discrimination
The extent that observed value (recorded data) matches true value
accuracy
A complex form of stimulus control, requiring discrimination between stimulus classes and stimulus generalization within a stimulus class
concept
A stimulus that evokes operant behavior because its presence signals the availability of reinforcement
discriminated stimulus
Recording whether the target behavior occurred at any time during the specified time interval
partial-interval recording
Stimulus that increases the reinforcing effectiveness of another stimulus due to learning history
CMO-T
A measurement of the number of occurrences of a behavior
count
Stimuli sharing a relationship that all evoke the same operant or respondent behavior
antecedent stimulus class
The force or intensity with which a response is emitted
magnituitde
Measurement conducted in a way that some responses of the target behavior may not be detected
discontinuous measurement
When observers are influenced by the knowledge that others are evaluating their data
observer reactivity
A variable that alters the effectiveness of a reinforcer (or punisher)
Motivating Operation
Recording the presence or absence of behaviors at the end of specified time intervals
momentary time sampling
A measurement of rates of response over time
celeration
Measurement that should detect all occurrences of the target behavior in an observation period
continuous measurement
Measuring behavior after the behavior has occurred using the effects that the behavior produced on the environment
measurement by permanent product
Recording whether the target behavior was occurring throughout the entire specified time interval
whole-interval recording
MO altering reinforcer effectiveness without dependence on learning history
UMO
Unconditioned Motivating Operation
Graphic depiction of the degree of stimulus generalization/discrimination, where a steep slope indicates strong discrimination
stimulus generalization gradient
The time from the onset of the behavior to its end
duration
count/time
rate
A discrete trial procedure for investigating conditional relations and stimulus equivalence
match-to-sample procedure
The physical form or shape of a behavior
topography
Stimulus acquiring MO effects by pairing with another MO, sharing its value- and behavior-altering effects
CMO-S
A ratio or proportion formed by combining the same dimensional quantities
percentage
A variable that signals the availability of a reinforcer (or punisher)
discriminated stimulus
When responding occurs only in the presence of SD, not in the presence of SΔ
stimulus discrimination
The extent to which repeated measurement of the same event yields the same value
reliability
The time between two successive responses
interresponse time
This type of variable will have a value-altering effect and behavior-altering effect
Motivating Operation
Stimuli evoking the same response but without shared physical or relational features
arbitrary stimulus class
Measurement that yields data directly relevant to the phenomenon measured
validity
Measure of how often behavior occurs
rate
The extent to which a researcher convinces themselves and others that the data should be trusted and interpreted
believability
Stimuli sharing common physical structures or relational properties
feature stimulus class
Stimulus acquiring MO effectiveness by preceding worsening or improvement, evoking behavior to address it
CMO-R
An unintended change in the way an observer uses a measurement system that results in measurement error
observer drift
Alteration in behavior frequency, latency, duration, or amplitude due to the presence or absence of antecedent stimuli
stimulus control
A time sampling variation in which group members doing a target behavior are tallied at specific points in time
planned activity check (PLACHECK)
When a behavior is evoked by other stimuli with similar physical properties to the controlling antecedent stimulus
stimulus generalization
When two or more separately established antecedents evoke the same response topography simultaneously
joint control
