Data can be collected on a target in a variety of ways. This is done by selecting a target type when a target is created. What follow are the available target types, a brief description, and a screenshot of the associated data collection screen that displays on the app.
This article defines the following target types:
[Anecdotal] [Conditional Discrimination] [Discrete Trial Target] [Duration] [Echoic] [Fluency/Rate] [Frequency] [Grouped Frequencies] [Jump-To Target] [Quantity] [Task Analysis] [Toileting] [Whole/Partial Interval]
Anecdotal Targets allow users to enter free-form textual responses for an individual item, instead of checking boxes.
Conditional Discrimination Targets allow data to be recorded to a set of stimuli compared against each other. Conditional Discrimination Targets can have 3-6 sub-Target stimuli and will require a prompt schedule to determine the desired Most to Least (MTL) prompt order.
The teaching trials prompt users to:
- Conduct Targets in a specific order.
- Use the controlling prompt in a MTL sequence with prompt fading.
- Place the stimulus array in a specific counterbalanced order.
An incorrect response will result in the Target prompting the user to increase the prompt level. The scoring allows users to evaluate whether there is a stimulus or positional bias.
DDT uses up to 8 prompt codes to measure a student’s response to a specific SD. If a Target is defined here as DTT, trials are performed in DTT sessions. Correct responses allow the user to move to the next Target, while incorrect responses lead to one correction trial before moving to the next Target.
Users can customize correction trials and other DTT settings under Setup subtab > Student Settings.
Duration Targets are used to record a time interval for a specific action. When creating a duration Target, users can specify a Target time period. Once the duration timer on the app reaches that goal, the timer begins to count upward and a notification will be displayed. Data are collected on the entire duration recorded, and are graphed showing the average duration for the day, as well as the total duration.
Echoic targets are for recording data on measurements of prosody. Users can rate characteristics of speech targets, including: Articulation, Volume, Speed, Tone, and Rhythm, for any specific echoic sound, word, or phrase. Users can rate student responses as a 0, .5, 1, or N/A across each of these dimensions. Users can also collect and store audio recordings of students' echoic responses. Sounds can be recorded on the device and synced to the portal.
Fluency/Rate targets allow users the ability to gather data that can be graphed as a rate. When creating a Fluency/Rate target, users will be asked to provide an amount of time that data should be gathered for the item. From the app, the user will start the target's timer, and tally responses to be captured within that interval.
A Frequency target is used to record the frequency or number of times a specific target occurs. These targets are visible on the bottom of the app during all data collection sessions and will tally each response throughout the day until midnight when the data collection intervals will be reset.
Grouped Frequencies group all users to compile a percentage for frequency targets (e.g., % prompted vs. % unprompted mands). Grouped Frequencies are graphed as the percentage of opportunities.
Jump-To targets are unique to Catalyst. This categorization is typically used for targets that should not automatically present during a DTT session, such as standing in line before recess, initiating peer conversation, or requesting to swing when on the playground. Jump-To targets allow users to access them at any time, during DTT sessions or otherwise.
Quantity targets allow users to score numerical amounts for a target. From the app, users can select a numerical value to assign to an item. This can be used to denote measures such as distance, amount, or quiz/test scores.
Task Analysis (TA) targets are single targets comprised of several ordered behaviors or steps. Data can be collected on each individual step and is graphed as a percentage of total steps for the specific trial. Users can customize the TA setting so that each step is either a pass/fail item, or users can record the prompt level needed to elicit the correct response for each step.
Note: Users can navigate away from a TA at any point during the scoring process and return to see steps that have initially been scored.
Toileting targets are used when implementing a toilet-training program. Use this target to capture sit duration, type of void, accidents and initiations in one place.
Whole Interval allows users to record target behaviors occurring throughout the duration of a user-specified interval. e.g., Whether a child is exhibiting the behavior for the entire interval.
Partial Interval allows users to define an Observe and Record interval for a skill. A Partial Interval target measures whether a target occurred at any point during a specified time interval.
