Question Type: Flash Profiling

Question Type: Flash Profiling

Overview

The Flash profiling testing is a sensory testing method that helps us understand the sensory positioning of products. It allows both trained and untrained panelists to evaluate a group of samples simultaneously and create their own attributes to describe the samples. Panelists are then prompted to rank the samples for each attribute they created.

This time- and cost-effective technique can be used at the initial stage of a project to create the sensory attributes for conventional Descriptive Analysis, for example. It can also be used as a rapid technique for identifying discriminating products in a large pool of products. Instead of using line or category scales, this method has the panelist rank the samples for the created attribute.


Question Compatibility

The Flash profiling question is compatible with the Standard test type.


Add the Question:

  1. In the Build tab of your test, in the left sliding pane, click the Preference question. This will add the question to the bottom of your questionnaire.


    You are able to drag and drop a new question to the location of your choice in your questionnaire.
    You can also move your questions after adding them by using the Move question option, or by using the cross-hairs handle.


  2. Click in the Add question name box and update the name to reflect the nature of the question. 

  3. The Preference question will have preset instructions for panelists. Click in the text area to update as needed.
Images, Wildcards , and Snippets can be added in the panelist instructions.



Question Options

By default, the Flash profiling question is set to appear for all samples at first opportunity. This means that if your questionnaire contains other question types in addition to the Flash profiling question, the Flash profiling question will be displayed to panelists once while other questions that may be set to display monadically will display for each sample individually in the position in the questionnaire you placed them in.

Enter the number of attributes panelists must evaluate. The default is 2.



Max attributes (unlimited = 0) 


Enter the total number of attributes panelists can evaluate. The default is 0 (unlimited).


The attributes created by multiple panelists that are spelt the same are consolidated in the analysis and in the exported raw data. Attributes that are not spelt the same are not consolidated in the analysis (e.g. 'crisp' and 'crispy' are treated as two different attributes). You have the flexibility to reorganize the raw data exported into an Excel file prior to analyzing it in the XLStat.
