  2. Overview

    Slide 2 - Overview

    • 1. Chapter 1: Theoretical Framework
    • 2. Chapters 2, 3 and 4: Grounding of Dominance in Bodily Strength
    • 3. Chapters 5, 6 and 7: Bodily actions influence Face Evaluation
    • 4. Chapter 8: General Discussion

  4. Research Questions

    Slide 4 - Research Questions

    • Can face evaluation be embodied?
    • Face evaluation is linked to our systems of perception and action or not?
    • Can the way our bodies interact with the surrounding environment shape the way we evaluate faces?
  5. Ecological Approach to Face Perception

    Slide 5 - Ecological Approach to Face Perception

    • Adaptive Function
    • Affordance
    • Perceiving is for doing
  6. The Two-Dimensional Model

    Slide 6 - The Two-Dimensional Model

  7. Chapters 2, 3 and 4

    Slide 10 - Chapters 2, 3 and 4

  8. Chapter 2

    Slide 11 - Chapter 2

    • HYPOTHESIS
    • Physical strength predicts social dominance
  9. Slide 12

    • p < .001
  10. Chapter 3

    Slide 15 - Chapter 3

    • HYPOTHESIS
    • Physical strength representation in the human face is very similar to the representation of dominance
  11. Chapter 4

    Slide 20 - Chapter 4

    • GOAL
    • Explore the relationship of physical strength and dominance across different spatial interactions
  12. Chapters 5, 6 and 7

    Slide 23 - Chapters 5, 6 and 7

  13. Chapter 5

    Slide 25 - Chapter 5

    • Hypothesis
    • Bodily postures change our sensitivity to different levels of facial dominance
  14. Chapter 6

    Slide 29 - Chapter 6

    • Hypothesis
    • Bodily postures change the mental representation of our own face
  15. How to create visual representations of mental images?

    Slide 30 - How to create visual representations of mental images?

    • Reverse Correlation Approach
    • Use of a two-forced choice paradigm
    • Every image has always the same base face
    • Random-noise pattern is added and subtracted
  16. Powerful Posture

    Slide 31 - Powerful Posture

    • Submissive Posture
  17. Chapter 7

    Slide 32 - Chapter 7

    • Hypothesis
    • Synchronous behavior change the representation of trustworthiness in the human face
  18. General Discussion

    Slide 38 - General Discussion

  19. Summary of the Main Findings

    Slide 39 - Summary of the Main Findings

    • Physical Strength predicts Dominance
    • The representation of Physical Strength and Dominance are very similar
    • Bodily interactions with others change how we represent trustworthiness
    • Physical Strength and Dominance are still related across different spatial relations
    • Bodily actions change how we perceive dominance
  20. General Discussion: Face evaluation as an embodied mechanism

    Slide 40 - General Discussion: Face evaluation as an embodied mechanism

  21. Base Image

    Slide 42 - Base Image

  22. Examples of Stimuli: (left) negative noise pattern superimposed on the base face, and (right) positive noise pattern superimposed on the base face.

    Slide 43 - Examples of Stimuli: (left) negative noise pattern superimposed on the base face, and (right) positive noise pattern superimposed on the base face.
