Measurements of Behavior Flashcards
Operationalism
belief that scientific concepts must be defined in terms of observable operations
Operational Definition
a precise description of a procedure used to empirically test a theoretical concept
Scientific Method
- make observations
- develop hypothesis
- test hypothesis
- gather data
- evaluate data
- evaluate results
- replicate
Variables
aspect of a testing condition that changes with different conditions
Types of Variables
- independent variables (IV)
- dependent variable (DV)
- confound variable (anything happening at the same time as the IV; undesired)
Writing Criteria for Operational Target Behavior Definitions
- accurate
- complete
- concise
- inclusions
- exclusions
Characteristics of Good Definitions
- objective : refers only to the observable
- clear : readable and unambiguous
- complete : delineate boundaries of definition
Purpose of Good Definitions
- precise and concise description
- reliable observation
- accurate recording
- agreement and replication
Testing a Definition
- can you count the number of occurrences? (should be yes)
- will a stranger know what to look for based on definition alone? (should be yes)
- can you break the target behavior down to smaller, more specific components? (should be no)
Behavioral Measurement
- frequency / rate
- duration
- latency
- locus
- topography
- force
Taking data
- event recording
- timing
- time sampling
Event Recording
procedures for detecting and recording the number of times a behavior is observed
Time Sampling
variety of methods for observing and recording behavior during intervals or at specific moments in time
observation is divided into intervals, presence or absence of behavior recorded for each interval
Partial Interval Recording
record whether the behavior happened at any time during the interval.
tends to underestimate high-frequency behavior and overestimate duration
Whole Interval Recording
at the end of each interval it is recorded if the behavior happened during the whole interval.
the longer the interval the more whole interval will underestimate the occurrence of the behavior
