    On Meaning: A Biosemiotic Approach. [REVIEW]Maria Isabel Aldinhas Ferreira - 2010 - Biosemiotics 3 (1):107-130.
    A life form and its environment constitute an essential unit, a microcosm. This microcosm is sustained by a privileged dialectic relationship in which the embedded agent- an entity endowed with a particular physical architecture- and its specific environment, coupled, mutually influence each other. Identical principles rule both the basic forms of semiotic organisation and the upper forms. When we distinguish these two levels of semiotic structuring we are distinguishing the semiotic relations that involve a stimulus-response relationship, which is dyadic in (...)

    The Concept of Umwelt Overlap and its Application to Cooperative Action in Multi-Agent Systems.Maria Isabel Aldinhas Ferreira & Miguel Gama Caldas - 2013 - Biosemiotics 6 (3):497-514.
    The present paper stems from the biosemiotic modelling of individual artificial cognition proposed by Ferreira and Caldas (2012) but goes further by introducing the concept of Umwelt Overlap. The introduction of this concept is of fundamental importance making the present model closer to natural cognition. In fact cognition can only be viewed as a purely individual phenomenon for analytical purposes. In nature it always involves the crisscrossing of the spheres of action of those sharing the same environmental bubble. Plus, the (...)

    Modelling Artificial Cognition in Biosemiotic Terms.Maria Isabel Aldinhas Ferreira & Miguel Gama Caldas - 2013 - Biosemiotics 6 (2):245-252.
    Stemming from Uexkull’s fundamental concepts of Umwelt and Innenwelt as developed in the biosemiotic approach of Ferreira 2010, 2011, the present work models mathematically the semiosis of cognition and proposes an artificial cognitive architecture to be deployed in a robotic structure.

    Typical Cyclical Behavioural Patterns: The Case of Routines, Rituals and Celebrations. [REVIEW]Maria Isabel Aldinhas Ferreira - 2014 - Biosemiotics 7 (1):63-72.
    The dynamics inherent to the life activity of all living systems presents itself in the form of regular patterns viewed by the observer as taking place in an extended timeline. Routines, rituals and celebrations, each in their own way, are defined by the typical cyclical behavioural patterns exhibited by individuals embedded in specific semiospheres. The particular nature of these semiospheres will determine the distinct patterns of behaviour to be adopted in different life contexts so that existential functions are fulfilled. The (...)

    Interactive Bodies: The Semiosis of Architectural Forms.Maria Isabel Aldinhas Ferreira - 2012 - Biosemiotics 5 (2):269-289.
    In this paper architectural forms are presented as symbolic forms issued from the complex semiosis that characterises human cognition (Ferreira (2007, 2010)). Being semiotic objects, these symbolic forms are, consequently, context- dependent_they emerge and have meaning, i.e., they are assigned a functional and/or aesthetic value, in particular physical, social and cultural frameworks. As it happens with all semiotic objects, architectural forms, whatever their nature, are not static but highly interactive. In fact, they act as agents of specific semiotic processes, engaged (...)
