Brunswikian Lens Model

A framework for the study of emotional communication

the lens model

cues

physical or social environment

observer (organism)

The Lens Model
  • is used in several fields to study how observers correctly and incorrectly use objective cues to perceive physical or social reality
  • cues have a probabilistic (uncertain) relation to the actual objects
  • a (same) cue can signal several objects in the environment
  • cues are (often) redundant
lens model research
Lens model research
  • Developed for the study of visual perception Brunswik (1956)
  • Immediately applied to judgment analysis (decision making, medical diagnosis, weather forecast)Hammond (1955)
  • Rapidly oriented towards interpersonal perception
    • Interpersonal dispositions(dominant, extraverted, agreeable …) Gifford (1994)
    • Intelligence Reynolds & Gifford (2001)
    • RapportBernieri & Gillis (2001)
    • Emotions (but only in music) Juslin (1998)
  • Some authors introduced modified versions of the lens

emotional communication

Loud voice

High pitched

Frown

Clenched fists

Shaking

Important issues:

- To be measured, cues must be identified a priori

- Inconsistencies on both sides (indiv. diff., broad categories)

- Cue utilization could be different

on the left and the right side (e.g. important cues not used)

Example:

cues

Vocal cues

Facial cues

Gestures

Other cues …

Expressed emotion

Emotional attribution

expressed anger ?

perception ofanger?

encoder

decoder

Emotional communication
implications for hmi

cues

Expressed emotion

Emotional attribution

relation of the cues to the perceived emotion

relation of the cues to the expressed emotion

matching

Implications for HMI
  • If matching is low…

Important for Automatic Recog..

Important for ECAs

  • ECA developers should focus on the relation of the cues to the perceived emotion
  • Automatic recognition system developers should focus on the relation of the cues to expressed emotion
  • (… Mind individual differences)
  • (… Mind broad/abstract categories)
