Category Induction Task
Use this task to have your participants put the stimuli in one of a number of categories chosen by you, or by them.
- Instruction hint
- This will be displayed on the screen during the task. Max 80 characters
- Extended instruction
- Shown when the user hovers over the hint. Max 500 characters
- Item Size
- Height of the stimuli in % of the width of the field. Default 8%. Must be between 2% and 20%. The width is adapted according to the original aspect ratio of the image.
- Change categories
- This creates a circle in the task, named "new category". If the participant drops a stimulus in this circle, the new category is created, and the stimulus placed in the new category. This also add close buttons ("x") to each of the circles, so they can be removed.
- Clone stimuli
- This creates a circle in the task, named "copy". If the participant drops a stimulus in this circle, the stimulus is copied. If you want the participant to be able to disregard unintentional copies, we suggest instructing them to create a "thrash bin" category.
- Maximum number of categories
- This is not currently enforced. In the future, the participant may be limited to this number of total categories if "Change Categories" is enabled. Default 100.
Each Category has the following parameters:
- The name of the category as shown to the participant.
- Is selector
- If you enable this, a subsequent task that has its Stimuli configured to be based on this Category Induction task, will include the stimuli in this category.
Participant responses are matched to qualification criteria differently if the participant was allowed to create their own categories or not:
If the participant was not allowed to create their own categories, the placements are compared based on the name of the category. If there is an 80% match with the placements in the criteria, the participant qualifies.
If the participant was allowed to create their own categories, category names may obviously differ from the ones chosen in the criteria, or even be meaningless (if so instructed). Therefore, in this case, clusters of stimuli are only defined by which other stimuli they are placed together with. There must be a 100% match with the criteria of these clusters.
