Unit 3 Flashcards
A characteristic of a phenomenon that exists independent of its measurement
Fundamental property
Temporal locus
Temporal extent
Repeatability
Fundamental properties of behavior
A quantifiable (measurable) aspect of a fundamental property
Dimensional Quantity
Latency, Duration, Countability, IRT, Rate, Celeration
Dimensional quantities of behavior
The quantitative results of deliberate, planned, and usually controlled observation
Data
Singular form of the term ‘data’
Datum

Characteristics of a good response definition
Continuous (direct) response measures
Directly measure a dimensional quantity of behavior
Do not measure behavior directly; most measure a dimensionless quantity (usually percent)
Discontinuous (indirect) response measures
Event
Latency
Duration
IRT
Dimensional quantities of continuous response measures
Record time observation began Count the responses Record time observation ended Divide: Count/unit of time Report as rate per unit of time
Event recording (frequency recording)
Record time observation began Record each antecedent Record each response Record time observation ended Report as (Responses/Antecedents)/unit of time
Event recording of restricted operants
Duration per session
Duration per occurrence
2 Types of Duration recording
Total amount of time an individual engages
in an activity
Duration per session
Amount of time a target behavior occupies
Duration per occurrence
Specify when to start recording (at the onset or the offset of the stimulus).
Specify when to stop recording (at the beginning or end of the response cycle).
Latency Recording
Start timing at the END of the response cycle.
Stop timing at the BEGINNING of the next response cycle.
Inter-response time (IRT) recording
Use when responses are distributed across the observation period, there are no significant outliers and you know the rate. Formula: Recording interval/count
Estimating mean IRT’s
Percent occurrence Trials to criterion Discrete categorization Partial interval recording Whole interval recording Momentary time sampling PLACHECK
Dimensionless quantities of discontinuous
response measures
Similar to event recording of a restricted or discriminated operant which has been converted into a percent
Percent occurrence
A special case of percent occurrence
Percent correct
The number of consecutive opportunities to respond required to achieve a performance standard. Record each opportunity to respond until the performance standard is met.
Trials to criterion
- Determine what one trial will be
- Decide how to report (number of trials
or number of block trials) - Record count as the measure
- Present data
Trials to criterion steps
A method for classifying responses into
discrete categories
Discrete categorization (coding)
