    • Overgeneralization and change: The role of acquisition in diachrony 

      Westergaard, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-30)
      Cournane (this volume) argues that child language acquisition is not only responsible for innovation in language change processes but that young learners are also responsible for the incrementation of the change in a language community. She sketches an inverted U-shaped model of incrementation (p. 143), where children’s initial overgeneralization of a linguistic phenomenon (input-divergence) is ...

    • Convergent catastrophes and the termination of the Arctic Norwegian Stone Age: A multi-proxy assessment of the demographic and adaptive responses of mid-Holocene collectors to biophysical forcing 

      Jørgensen, Erlend Kirkeng; Riede, Felix (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-31)
      Using multiple archeological and paleoenvironmental proxies, this paper makes the case for a climate-induced convergent catastrophe among the human population of terminal Stone Age Arctic Norway. We show that climatic changes correlate with the termination of the so-called Gressbakken phase (4200–3500 cal BP), and unpack the middle-range mechanisms linking the Gressbakken termination to contemporaneous ...

      Le, Thanh P.; Cowan, Tovah; Schwartz, Elana K.; Elvevåg, Brita; Holmlund, Terje Bektesevic; Foltz, Peter W.; Barkus, Emma; Cohen, Alex S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-19)
      Poor social connection or loneliness is a prominent feature of schizotypy and may exacerbate psychosis risk. Previous studies have examined the inter-relationships between loneliness and psychosis risk, but critically, they have largely been conducted in non-clinical samples or exclusively used laboratory questionnaires with limited consideration of the heterogeneity within schizotypy (i.e., positive, ...
    • Sámi (re)presentation in a differentiating museumscape: Revisiting the art-culture system 

      Grini, Monica (Journal article; Tidsskriftartikkel, 2020-01-28)
      The article addresses how Sámi culture is presented by museums in Oslo. One of the findings is that the old binary of “art” and “ethnographica” is still common in this museumscape. This reflects the historical divide between the art museum showing “European” and “Norwegian” art, and the ethnographic museum showing the arts of “the rest”. It is argued that Sámi artists, works, themes, and practices ...
