<p>Let's say that we have a set of shapes. They can be grouped according to the different Gestalt laws of grouping. However, different Gestalt principles will divide the set into different groups, e.g. grouping by proximity will give us A,B,C | D,E,F, and grouping by similarity will give us A,B,D,F | C, E.</p>

<p>Is it possible to predict which laws would gain precedence over the others? What's the "order of processing" of the different visual properties?</p>

This is a good simple experiment to do for psychologists who lack ideas.

It's a shame there's not much discussion about this, especially from the UX community. With limited theory in UX design, Gestalt principles are one of the few foundations providing a scientific basis for UX decisions. Yet, they seem to be rarely used in practice. If they were, questions like this one would be more common.

If a discovery has been made on this topic, it'd probably be mentioned here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482144/ <A Century of Gestalt Psychology in Visual Perception I.

Is it possible to predict which laws would gain precedence over the others? What's the "order of processing" of the different visual properties?

I am not sure whether there is a hierarchy as such but there is the concept of [Global vs Local Precedence](https://doi.org/10.1038/s41598-017-18664-5). Global precedence can be seen to be closely related to the Gestalt principles of grouping (particularly [the principle of similarity](https://www.usertesting.com/blog/gestalt-principles#similarity)) in that the global whole is a grouping of proximal and similar objects.

Global precedence was first studied using Navon figures ([Navon, 1977](https://doi.org/10.1016/0010-0285(77)90012-3)), where many small letters are arranged to form a larger letter that either does or does not match.

Variations of the original Navon figures include both shapes and objects ([Poirel, et al. 2008](https://doi.org/10.1016/j.actpsy.2006.12.001)).

In general, reaction time for identifying the larger letter is faster than for the smaller letters that make up the shape ([Navon, 1977](https://doi.org/10.1016/0010-0285(77)90012-3)). Navon directed participants to focus either globally (to the overall shape of the letter formed out of the smaller letters) or locally (to the small letters making up the overall shape of a letter) that were consistent, neutral, or conflicting on the global and local levels.

| Consistent | Neutral | Conflicting |
| --- | --- | --- |
| TTTTTTTTTTTT TTTTTTTTTTTT TTTT TTTT TTTT TTTT TTTT | ++++++++++++ ++++++++++++ ++++ ++++ ++++ ++++ ++++ | SSSSSSSSSSSS SSSSSSSSSSSS SSSS SSSS SSSS SSSS SSSS |

In general, reaction time for identifying the larger letter (global) is faster than for the smaller letters that make up the shape (local), showing global precedence.

However, global precedence is not a universal phenomenon ([Davidoff, et al. 2008](https://doi.org/10.1016/j.cognition.2008.06.004)). As well as Davidoff's study, Poirel, et al.
