This introduction to a special section of Phenomenology and the Cognitive Sciences reviews some historical and contemporary results concerning the role of development in cognition and experience, arguing that at this juncture development is an important topic for research in phenomenology and the cognitive sciences. It then suggests some ways in which the concept of development is in need of rethinking, in relation to the phenomena, and reviews the contributions that articles in the section make toward this purpose.

I engage phenomenological and empirical perspectives on dialogical relations in infancy in a mutually enlightening and challenging relation. On the one hand, the empirical contributions provide evidence for the primacy of first-to-second person interrelatedness in human sociality, as opposed to the claim of primary syncretism heralded by Merleau-Ponty, and also in distinction from the ego-alter ego model routinely used in phenomenology. On the other hand, phenomenological considerations regarding the lived affective experience of dialogical relatedness enrich and render intelligible the psychological (...) accounts of dialogue in terms of observable behavior. Phenomenological and empirical perspectives on dialogical relatedness thus combine to offer an affectively charged and conversationally patterned notion of primary intersubjectivity in the I-you mode.
