    A comparison of the cognitive actions of designers in geometry-based and parametric design environments
    (2020) Tunger, Cetin; Pektas, Sule Tasli; 0000-0003-0596-6405; B-9453-2008
    Purpose - This paper aims to compare designers' cognitive behaviors in geometry-based modeling environments (GMEs) and parametric design environments (PDEs). Design/methodology/approach - This study used Rhinoceros as the geometric and Grasshopper as the parametric design tool in an experimental setting. Designers' cognitive behaviors were investigated by using the retrospective protocol analysis method with a content-oriented approach. Findings - The results indicated that the participants performed more cognitive actions per minute in the PDE because of the extra algorithmic space that such environments include. On the other hand, the students viewed their designs more and focused more on product user relation in the geometric modeling environment. While the students followed a top-down process and produced less number of topologically different design alternatives with the parametric design tool, they had more goal setting activities and higher number of alternative designs in the geometric modeling environment. Originality/value - This study indicates that cognitive behaviors of designers in GMEs and PDF-s differ significantly and these differences entail further attention from researchers and educators.

    A scientometric analysis and review of spatial cognition studies within the framework of neuroscience and architecture
    (2021) Pektas, Sule Tasli; 0000-0003-0596-6405; B-9453-2008
    Although there is a large potential overlap between neuroscience and architecture, the studies bridging these fields are rare and newly emerging. Moreover, a gap is observed between the constructs, terminologies and research methods of architecture and neuroscience. In order to alleviate these problems, this study investigates main research themes and developments in spatial cognition research over the past two decades on the basis of the author keywords of published articles. Vosviewer (c) bibliometric analysis software was utilized to conduct keyword co-occurrence analysis, keyword clustering, and timeline analysis of keywords and current research on spatial cognition is discussed accordingly. The paper also reviews existing research at the intersection of neuroscience and architecture and comments on how this nexus could evolve in the future. It is concluded that embodied spatial cognition and affordances of architectural design provide a robust framework to guide further studies in this track.
