Behavior Measurement Procedures

14 important questions on Behavior Measurement Procedures

What is Behavior Measurement?

The process of tracking data and analyzing specific dimensions of behavior over time. Concerns taking quantitative data.

What are examples of continuous and discontinuous behavior measurement?

Continuous:
  • frequency/rate
  • duration
  • percentage correct

Discontinuous:
  • interval (partial and whole)
  • momentary time sampling
  

What are the dangers of inaccurate data?

Data should reflect the true nature of the behavior! Inaccurate data collection can cause a variety of problems for the learner and jeopardize the effectiveness of the intervention procedures. It can lead to:
  • erroneous decision making
  • problems with instructor consistency
  • inhibits monitoring of actual progress
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

What are 2 primary guidelines for data collection?

  1. Data should be recorded immediately after the occurrence of the behavior to facilitate validity and accuracy.
  2. Data should contain all relevant information regarding the observation and occurrence of the behavior to provide a complete account of the behavior.

What is Inter Observer Agreement (IOA)?

Method of measuring data reliability by calculating the degree to which two people agree on a behavior that they have both observed, measured, and recorded.
  • High agreement = valid data (high similarity means high reliability, good data)
  • Low agreement = invalid data (low similarity means low reliability, problematic data)

What are some considerations for data collection?

  • Some behaviors can be easily observed and recorded throughout a session or period of time
  • Other behaviors may be difficult to record for extended periods of time
  • Continuous vs discontinuous measurement procedures

What are the 2 main categories of recording procedures within continuous measurement?

  1. Event recording
    1. Count
    2. Frequency/rate
  2. Timing
    1. Duration
    2. Latency
    3. Inter Response Time (IRT)

What is count (from event recording within continuous measurement)?

  • Counting the number of times that a behavior occurs
  • Appropriate for behaviors that have a very clear, discrete onset and offset
  • Requires continuous observation and recording in order to accurately measure
  • Used when the observation period is always a consistent length of time

What is frequency (from event recording within continuous measurement)?

  • Counting the number of times a particular behavior occurs within a standard unit of time
  • Appropriate for behaviors that have a very clear, discrete onset and offset
  • Useful measurement for free operant behaviors (behaviors that can happen at any time, not dependent on a certain SD being presented)

What is rate (from event recording within continuous measurement)?

  • How often the behavior occurs per unit of time
  • Used when the observation period varies in duration

What is duration (from timing within continuous measurement)?

  • Measurement of the length of time a behavior occurs, from onset to offset
  • Duration can be measured for each behavior or for total cumulative time engaged in the behavior
  • Duration of behavior should be reported in standard units of time
  • Can be effective for behaviors of long duration

What is Inter Response Time or IRT (from timing within continuous measurement)?

  • The amount of time between consecutive occurrences of the same behavior or how much time passes between one occurrence of the behavior to the next occurrence
  • Used to determine the average time between occurrences of the behavior

What are 3 other behavior measurement procedures?

  1. Percentage/trial by trial data
  2. Permanent Product Data
  3. Task Analysis Data

What is percentage data/trial by trial data?

A comparison of two quantities or types of data for the same behavior.
  • Typically used to determine how often the behavior occurs within a set number of opportunities to respond
  • Percentage = the percentage of time the behavior occurs when the opportunity to respond is presented

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
