This book of proceedings collects papers referring to three key events celebrated at the University of Trieste on 27th and 28th November, 2014:1) the sixtieth anniversary of the Kanizsa triangle; 2) the twenty-second Kanizsa Lecture; 3) the Trieste Symposium on Perception and Cognition, TSPC2014. The volume opens with the English translation of Kanizsa’s report included in the proceedings of the tenth meeting of
Italian psychologists in Chianciano Terme (10-14 October 1954), which features the first published version of the illusory triangle that would have become an icon of vision science. As a second contribution, the volume includes the speaker notes of the twenty-second Kanizsa Lecture, held by the 2014 invited speaker Barbara Gillam, University of New South Wales, Sydney, Australia, on Thursday 27 November. The
notes drive the reader through the lecture and provide a rich set of demonstrations on how perceptual grouping affects different levels of vision: from low (e.g., disparity coding) to mid level (e.g., subjective contour formation). The third part of the volume collects talks and posters presented at TSPC2014, organized by the Psychology Unit of the Department of Life Sciences, University of Trieste. The symposium included two oral sessions (on 27th and 28th November) and a poster session (November 28th).
