Semiotics Semiotics Presentation Transcript

  • Semiotics Edgar Kenji Tanaka
  • Agenda
    • What is semiotics?
    • What is a sign?
    • Types of signs
    • Why study semiotics?
    • Conclusions
  • What is semiotics?
    • Also called semiology
    • Comes from greek semeîon which means sign
    • Science which studies the role of signs as part of social life (Saussure)
    • Formal doctrine of signs (Peirce)
    • Investigates the nature of signs and the laws governing them
  • Studies in semiotics
    • Semiotics studies are in art, literature, anthropology, mass media, psychoanalysis, biology, education and computers 
    • Semiotics are studied by semioticians ( semioticistas in Portuguese)
  • What is a sign?

  • What is a sign?
    • Saussure and Peirce were concerned with the definition of sign
    • Words, images, sounds, gestures, objects
  • Ferdinand de Saussure
    • November 26, 1857 – February 22, 1913
    • Swiss linguist
    • Father of the 20-century linguistics
  • Saussure´s sign definition the form which the sign takes signification the concept it represents
  • Saussure´s sign definition
    • “ the sign is the whole that results from the association of the signifier with the signified” (Saussure)
    • Signified and Signifier are both psychological (form rather than substance)
    • Saussure´s model of the sign refers only to a concept and not to a thing
  • Saussure
    • Example
    Concept of a tree Word ‘tree’, picture of a tree, pronunciation of ‘tree’
  • Saussure
    • Example
      • Signifier – word ‘open’
      • Signified – that the shop is open for business
  • Saussure
    • Same signifier can stand for different signifieds depending on the context
    • Saussure was focusing on the linguistic sign (such as a word)
    • The link between signified and signifier is arbitrary (nothing ‘treeish’ about word ‘tree’)
    • No specific signifier is ‘naturally’ more suited to a signified than another
    • Saussure was more concerned about linguistic signs and speech
  • Charles Sanders Peirce
    • September 10, 1839 – April 19, 1914
    • American logician, philosopher, mathematician and scientist
    • Born in Cambridge, Massachusetts
    • Contributions to philosophy, mathematics, logic and semiotics
  • Peirce´s sign definition
    • “ Something which stands to somebody for something in respect or capacity” (Peirce)
  • Peirce´s sign definition
    • Representamen – form which the sign takes (not necessarily material)
    • Object – to which the sign refers
    • Interpretant – idea, interpretation in mind
  • 3 classes of signs
    • Symbol – signifier does not resemble the signified (fundamentally arbitrary or purely conventional)
    • Icon – signifier is perceived as resembling or imitating the signified
    • Index – signifier is directly connected in some way (physically or causally) to the signified
  • Highlights
    • There are no pure icons – there is always na element of cultural convention involved
    • Iconic and Indexical signs are more likely to be read as ‘natural’ than symbolic signs. (HCI)  Abstract UI (youtube)
  • Why should we study semiotics?
    • “ ...writings of semioticians have a reputation for being dense with jargon”
    • Semiotics is important because it can help us not to take ‘reality’ for granted as something having a purely objective existence which is independent of human interpretation
    • Information or meaning is NOT contained in the world
    • We live in a world of signs and we have no way of understanding anything except through signs
    • Deconstructing and contesting the realities of signs can reveal whose realities are privileged and whose are supressed
  • Conclusions
    • Peirce´s sign model seems to be more complete than Saussure´s
    • Saussure was more concerned with linguistics
    • Peirce´s model seems to be more adequate in the HCI context
    • Semiotics can help understand signs in computers
    • Semiotics can help in anything involving communication such as computer interfaces
  • Next steps?
    • Search for material involving HCI and semiotics
