  1. PSY 2403:Human-Technology InteractionLecture no. 4: The Embodied Mind Paradigm: Kjell Ivar ØvergårdCand. Polit

  2. Aim of this lecture You should: • Understand the central tenets of The Embodied Mind approach. • Be able to differentiate Embodiment from the information processing approach to Human-Technology Interaction. • Describe what the placement of the Embodied Mind-approach in relation to the design process. • Be able to put the Embodied Mind approach into the historical perspective of Human Factors-research. • Ask interesting questions during and after the lecture!

  3. The Embodied Mind approach [1]:History • Surfaced in the phenomenological philosophy of of Heidegger (1927) and Merleau-Ponty (1962) • Appeared in psychology & movement science in the mid./late1970’s • Began to influence Human Factors research during the mid./late 1980’s • Altered the focus away from information processing towards meaningful representations and distributed activity

  4. The embodied mind approach [2]:Central aspects • Cognition and bodily movements are inseparable • There are no disembodied planner or problem solver in the brain • The brain is an coordinative organ, not the seat of problem solving and cognition • The focus are on human activity as a temporally and spatially extended process. • Human cognition and movement are emergent properties of a reciprocal interaction between a biological system (the body) and an environment

  5. Embodiment & Human-Technology Interaction

  6. Embodiment: Two aspects • There are two different conceptualisations of ’Embodiment’ (see Hirose, 2002). • 1) ’The state of being embodied’ • This aspect is partly related to ontology • 2) ’The act of embodying’ • The way which humans relate to/in the world

  7. ’The state of being embodied’ • The mental structures of humans are related to/shaped by their bodily constitution and the world that this body inhabits (see Lakoff & Johnson, 1999). • ”That thought is thus embodied-containing within it the very essence of our bodily experience. ... What Infants do in everyday life, what they perceive, how they act, and what they remember are joined seamlessly to how they think.” (Thelen, 1995, p. 71) • ”... thinking grounded in and inseparable from bodily action.” (Thelen, 1995, p. 71, our italics)

  8. ”The act of embodying [1]” • May be described as the adaptation to new tools or environments through active use [or training], where the object are incorporated into the bodily and perceptual framework of the user. • ”Once the stick has become a familiar instrument, the world of feelable things recedes and now begins, not at the outer sking of the hand, but at the end of the stick. ... the stick is no longer an object perceived by the blind man, but an instrument with which he perceives. It is a bodily auxiliary, and extention of the bodily synthesis.” (Merleau-Ponty, 1962, pp. 175-176)

  9. ”The act of embodying” [2] • The ”blind man’s stick”-example show that the body does not end at the skin, but rather can extend out into the environment through [with the aid of] the tool. • When the tool/technology is embodied, the user acts directly on the task. • The tool becomes nonexistent as an object, and does not hinder the activity. • May be said to describe an aspect of what is called ”automated activity” (but this term is problematic as it is related to a set of different ontological statements!)

  10. The act of embodying [3] • Embodying is a continuous process, similar to perceptual adaptation. • It involves a change in the perception of both self and the environment. • Some technologies are difficult to use/learn, -they are not as easily embodied. • NOTE: Embodying is NOT the same as ’learning to use’!!

  11. The act of embodying: [4] Distributed Cognition • Cognition and problem solving also extends outside the boundaries of the skull, similarly to the extention of the body. • The mental activites of humans are distributed across an ecological context. • Called distributed cognition • Are spatially and temporally distributed (Happen in space, over time) • We use external props to guide problem solving, (e.g. maps and compass to guide navigation by high-speed boat)

  12. Distributed cognition (1) • Example of a text from the syllabus • The important characteristics of the text are similar to the other parts • However, this text can be altered to better fit with the reader (or ’operator’)

  13. Distributed cognition (2) • Same text as previous page, but now altered to fit the reader • Use of pen and paper is one of the most common aids for problem solving • Structuring of the environment to ease problem solving • This page is as much a part of human cognition as thinking/visualizing/ talking • In principle similar to navigation with maps and compass.

  14. Embodiment and Design [1] • Humans are primarily good at pattern recognition & formation, and at coordinating bodily movements. • Humans are generally poor at logical reasoning and planning • The main elements that cognitive psychology have studied  • Humans improve their mental computational power by structuring their environment, thereby allowing more complex problem solving.

  15. Embodiment and design [2] • Effective interfaces should have a meaningful and functional relationship between controls and effects. • ’Embodied’ Interfaces should (in addition) allow for: • A Possibility to distibute problem solving activities by restructuring the working space • Physical interaction with the interface • Alteration of the interface to fit changing task demands

  16. Ecological Interaction Properties • Describes physical/phenomenal characteristics of interfaces which affects the ’directness’ of the interface • Directness may be translated as the degree of problemsolving necessary to effectively interact with an interface • Direct interaction may be described as natural fluent interaction based on existing human sensori-motor qualities • Indirect interaction are equivalent with explicit abstract reasoning and/or problem solving • Human-Technology Interaction moves along the direct-indirect continuum all the time. • There may be other and/or better description of properties!

  17. EIP [2] • The Paper by Hoff et al is mainly related to the phenomenal qualities of interfaces. • Physical characteristics related to performance are also possible to describe. • It is to some degrees possible to predict performance from physical characteristics

  18. EIP & Embodiment: ”Knowledge in the World” • Affordances: Action-possibilies in the environment • Related to the individual actor/observer • Neither subjective nor objective – but both • Directly meaningful for an actor • Can be perceived directly, are specified by the ambient energy radiated from the environment
