Karl M. Dallenbach (October 20, 1887 in Champaign, Illinois – December 23, 1971 in Austin, Texas)[1] was an American experimental psychologist whose interests in psychology were heavily influenced by John Wallace Baird.
[1] Dallenbach did not develop any major theories and he never wrote a book.
[3] However, his 94 core publications (from a total of 234) can be organized around seven themes: attention, cutaneous sensitivity, somesthetic perception, taste, visual perception, 'facial' vision, and memory and cognitive processes.
Some consider Dallenbach's studies of attention to be his most important of these contributions,[2] while others maintain that his studies on facial vision and retention during sleep belong to the classical psy- chological literature.
[3] Dallenbach owned the journal for the next forty-eight years and was its editor for forty-two.
