Temporal Check All That Apply (TCATA) is a method for describing the multidimensional sensory properties of samples as they evolve over time. Selection and deselection of attributes are tracked continuously over time, allowing participants to characterize the evolution of sensory changes in samples. Graphical results make it possible to visualize the evolution of sensory profiles over time and to compare samples. TCATA data must be balanced, meaning that each participant must evaluate all samples in each session.

  4. Under the OPTIONS tab to the right, specify the options to enable.

    • Timer Type – Controls how the evaluation can stop/end. 
      • Timed Stop – The evaluation automatically stops when the evaluation time ends.
      • Manual Stop – The evaluation ends when the participant clicks the [Stop] button.
      • Dual Stop – The evaluation automatically stops when the evaluation time ends or when the participant clicks the [Stop] button. 
    • Time (seconds) – The amount of time in seconds the TCATA evaluation is presented.
    • Auto Advance – When the time completes the survey page is automatically submitted.
    • Show Timer – Display the active timer, counting down the remaining time in the evaluation.
    • Allow Manual Start – Requires the participant to click the [Start] button to begin the evaluation.
    • Auto Start – The evaluation time automatically starts when the question displays.
    • Response Randomization – Randomize the order of attributes.
    • Show Pop-up Notifications – Display a customized pop-up message at a specified time during the evaluation.



  5. Under the REPORTING tab to the right, specify the Time Increment to report the data by.



  6. Click anywhere off the window to close it. The question updates on the page.



  7. When finished with the questionnaire, click on the X in the upper-right corner of a questionnaire to close it. If you have outstanding changes, you will be prompted to save. RedJade returns you to the Surveys page for the test. 


  8. Continue with the Test Wizard to Create and Approve a Design then Preview and Launch Test to collect data.


  9. Click on [PREVIEW] from the Test Dashboard to review an example of how the question appears for consumers.

    • When Allow Manual Start is selected in the question options, the participant must click the [Start] button to begin the evaluation.
    • Otherwise, click an attribute to begin the evaluation. The selected attribute button turns black.
    • Click an attribute again to deselect it. The deselected attribute button turns grey.
    • When Show Timer is selected in the question options, the active timer will display counting down the remaining time in the evaluation.
    • Once the evaluation time completes, the attribute buttons are disabled and the [NEXT] button displays. If Auto Advance is selected in the question options, the page will automatically submit.



TCATA Analysis and Raw Data

The TCATA raw data can be downloaded to complete the analysis through a third-party application of your choice. TCATA Analysis within RedJade is not yet available. A "Coming Soon" message displays in the Topline Analysis.

To download the TCATA raw data:

  1. From the main menu, select ANALYSES.



  2. From the Analyses dashboard, search for the test and click on [VIEW].



  3. Click on [Download Raw Data].



  4. Open the Excel raw data file and select the TCATA Matrix tab.

    The data has as many rows as there are sample, participant and attribute combinations, and as many columns as there are time increments. The data is saved in binary form (1 if the attribute is selected, 0 otherwise).



  5. You can use the raw data matrix to complete the TCATA Analysis through a third-party application of your choice, for example XLSTAT - ANALYSIS OF TEMPORAL CHECK-ALL-THAT-APPLY (TCATA) DATA IN EXCEL.
