In the figure, dots are closer within small clusters than between clusters. Which Gestalt grouping principle organizes them?

The figure shows identical circles. Which principle makes viewers see them as three horizontal bands?

The figure shows an even grid where some circles share the same color, so viewers see color-based columns. Which principle is at work?

In the figure, spacing is even, but matching shapes seem to belong together. Which Gestalt principle explains that grouping?

The figure leaves gaps in a familiar outline, yet viewers perceive a complete shape. Which principle explains that perception?

A broken outline in the figure is still seen as one complete object. Which Gestalt principle best fits this display?

The figure shows crossing paths, and viewers tend to follow the smooth path rather than sharp turns. Which grouping principle is shown?
