Talk:Illusory contours

Merger proposal
Formal request has been received to merge: Ehrenstein illusion into Illusory contours; dated: October 2020. Proposer's Rationale: stubby sub-set of the target article. Discuss here. GenQuest "Talk to Me" 01:02, 12 October 2020 (UTC)

If these are merged then it should be done under a new page - Illusory Form - as these to effects both create illusory form, but for different (although related) reasons. Another Partial Success (talk) 09:58, 26 March 2021 (UTC)
 * My problem with the term 'Illusory Form' is that the term 'Form' also evokes other possibilities: three-dimensional forms, forms in motion (which evoke the detection of patterns with spatial frequencies), material forms (which are real), and algebraic forms (which are mathematical abstractions). The articles under discussion, Ehrenstein illusion and Illusory contours, describe two-dimensional visual patterns which exemplify the human brain filling-in a percept (a perceived form). --Ancheta Wis   (talk  &#124; contribs) 11:00, 26 March 2021 (UTC)
 * What do the RS call them? GenQuest  "scribble" 13:50, 12 May 2021 (UTC)
 * Both Ehrenstein illusion and Illusory contours are visual/optical phenomena. To merge them into a Form article is feature creep into other sensory domains involving touch, motion, abstraction ... which are ill-defined compared to Visual systems. --Ancheta Wis   (talk  &#124; contribs) 18:36, 12 May 2021 (UTC)
