It is a familiar experience to perceive a material object as maintaining a stable shape even though it projects differently shaped images on our retina as we move with respect to it, or as maintaining a stable color throughout changes in the way the object is illuminated. We also perceive sounds as maintaining constant timbre and loudness when the context and the spatial relations between us and the sound source change over time. But where does this perceptual invariance ‘come from’? (...) What is it about our perceptual systems that makes them able to ‘transform’ incoming unstable and fluctuating sensory inputs into generally stable and coherent conscious experiences? And what exactly do we experience as invariant in cases like those described above? There are two main approaches to the Problem of Perceptual Invariance: the Local-Inferential approach and the Global-Structural approach. Although both approaches include an account of the sub-personal perceptual mechanisms ‘stabilizing’ variant and invariant components in incoming sensory stimulation and a proposal regarding the phenomenology of perceptual invariance, in this paper I argue that the latter provides a better solution to the problem overall.

Confronting any science studies or learning sciences researcher in the 21st century is the reality of interdisciplinary science. New hybrid fields1 collaboratively build new concepts, combine models from two or more disciplines and forge inter-reliant relationships among specialists with different skill sets to solve new problems. This paper emerges from our recognition that inescapable psychological factors, including identity dynamics, must be described and analyzed in order to better understand the social and cognitive practices specific to interdisciplinary science. In analysis of (...) the foundations and opportunities for an... (shrink)

The journal Mind is now a wholly philosophical journal. At the time of its founding, in 1876, however, its mission was rather different in character. Its aim was to discover whether scientific psychology was a truly viable enterprise and, if so, what its boundaries with philosophy, with other scientific disciplines, and with the earlier generation of discredited attempts at `scientific' studies of the mind (e.g. phrenology, mesmerism) might be. Although at first Mind published mostly philosophical pieces and literature reviews, by (...) the mid-1880s it was publishing primary experimental research, mostly by American psychologists who as yet had few outlets of their own. For a time it was the leading journal of experimental psychology in the English-speaking world. As the international competition among scientific and scholarly journals intensified in the 1890s, however, Mind started to lose its share of experimental contributions, and with the editorial takeover of the journal of George Stout in 1892, the journal soon became one dedicated purely to philosophy.

This paper studies the constellations of attitudes––sentimental, moral, epistemological, and social––that three leading psychologists active in turn-of-the-twentieth-century America took to be essential to the production of scientific knowledge. William James, G. Stanley Hall, and Edward Titchener located the virtues and traits proper to the scientific frame of mind, and combined them into normative images of the man of science, or, ‘scientific personae’ as I use the term here. I argue that their competing formulations of the scientific ethos informed their psychological (...) practice and epistemological commitments. James, Hall, and Titchener mobilized their representations of the man of science in order to reconfigure the field of psychology and redefine its boundaries, as well as to promote forms of sociability and define the proper role of scientists both within the academy and in the wider polity.

Histories of psychology regularly celebrate the foundational role played in the development of early American psychology by Darwin's theory of evolution through natural selection, and in particular the development of functional psychology and behaviorism. In this article it is argued that although Darwin's theory did play an influential role, early American psychology did not generally reflect the hereditarian determinism of his theory of evolution by natural selection. However, early American psychologists did accept one critical implication of Darwin's theory, which is (...) that evolution by natural selection does not ensure the highest development of the human race. This partly explains the social interventive zeal that was a distinctive feature of early American psychology. (shrink)

We historically and conceptually situate distributed cognition by drawing attention to important similarities in assumptions and methods with those of American ?functional psychology? as it emerged in contrast and complement to controlled laboratory study of the structural components and primitive ?elements? of consciousness. Functional psychology foregrounded the adaptive features of cognitive processes in environments, and adopted as a unit of analysis the overall situation of organism and environment. A methodological implication of this emphasis was, to the extent possible, the study (...) of cognitive and other processes in the natural (real world) contexts in which they occur. We therefore emphasize commonalities and differences between functional psychology and D-Cog. One purpose of the comparison is to consider the extent to which criticisms directed at functional psychology are relevant to D-Cog. We also examine the relation between functional psychology and philosophical pragmatism and conclude that D-Cog's conceptual framework would be strengthened through more explicit adoption of philosophical pragmatism, consistent with the eventual trajectory of functional psychology.
