During the 1890s William James and Carl Georg Lange's works on emotion were discussed in psychological journals under the heading of the “James–Lange theory” of emotion. Yet Lange's work is much less known because it was linked with James' theory and because later neurophysiological research demonstrated that Lange's proposed mechanism for processing emotion could not be correct. However, a reappraisal of his work is warranted for several reasons: For his attempt to ground the emotions in physiology at a time when (...) psychologists advocated a purely spiritual conception of emotions, for his insights in biological psychiatry, for postulating a neuroanatomical centre for processing emotion. Finally, in the light of contemporary research, because Lange deconstructed the emotions into combinations of components, which makes his work a precursor to component and appraisal theories of emotion.

Illustrations played an important role in the articulation of Wundt’s experimental program. Focusing on the woodcuts of apparatus and experimental designs in the six editions of his Grundzüge der physiologischen Psychologie (published between 1873 and 1911), we investigate the uses and functions of illustrations in the experimental culture of the physiological and psychological sciences. We will first present some statistics on the increasing number of illustrations Wundt included in each new edition of his handbook. Next we will show how Wundt (...) managed to introduce the material and literary technologies of physiology into the ‘new psychology’. The distribution of Wundt’s material technology will be further demonstrated by highlighting the crucial role of technicians and instrument-makers. We will use Shapin and Schaffer’s notions of the ‘three technologies’ and ‘virtual witnessing’, combined with Latour’s concept of ‘immutable mobiles’, as analytical tools to explore the strategic aspects of Wundt’s illustrations.
