Ok. I’m going through papers I’ve read. First hit: There’s a reference to his work on straight lines in a paper I read in 2020 on human vision and lines, “The awakening of Attneave’s sleeping cat: Identification of everyday objects on the basis of straight-line versions of outlines” – I’d vaguely recognized a name “Hoffman” associated with straight lines and yes, it’s the same guy. “we can also examine whether segmentations of these stimuli confirm segmentation rules like the minima rule by Hoffman and Richards (1984; see De Winter and Wagemans 2006), whether fragmented versions are indeed easier to recognise with fragments around inflections than around extrema, as suggested in the study by Kennedy and Domander (1985; see Panis et al 2008), and whether curvature extrema are more salient than other points, as suggested by Attneave’s first demonstration (figure 1a) and confirmed by a more thorough study with random shapes (Norman et al 2001; see De Winter and Wagemans 2008). “
