Emotion in Cognition and Action:

WP7 Exemplars

WP4 Workshop

WP7: Emotion in Cognition and Action


The Task of WP7

WP7 task (Exemplar):

Shared understanding of mechanisms underlying the involvement of emotion in
cognition and action (decision making)

Comparative approaches to emotion
oriented agent architectures: assumptions,
guidelines, and integration challenges

Working groups within this task:

WG1: Emotion in “lower
lever” cognition and action


WG2: Emotion in “higher
level” cognition and action

Uni. Bari
, France Telecom RD, QUB, EPFL, GERG

WG3: Bridging gap between “lower
” and “higher
level” cognition & action


WG4: Emotion in Social Cognition and Interaction

UH, Paris8


WP7: Emotion in Cognition and Action


WG1: Emotion in “lower
level” C&A

“fast pathway”; Embodied AI approach (Perception
Action models)

Mechanisms underlying emotional modulation of cognition & action:

Neuromodulation of cognition and action (of basic robotic architectures)

Incremental approach
> increasing complexity and flexibility

up approach
> how emotions “emerge”

Critical analysis from psychology, neuroscience, philosophy

Principled design of “emotivated” architecture for action selection

“Modulated” robot architecture (UH), analysis in terms of appraisal

Feedback from appraisal theory to add relevant elements; e.g. what triggers
“neuromodulations”? nature of stimuli, what is relevant, how to process them

Focus on perception
> from signals to signs of emotion in robots? (WP4)

Integration of paradigms (cybernetics, dynamical systems, ethology,
neuromodulation, appraisal)


WP7: Emotion in Cognition and Action


WG2: Emotion in “higher
level” C&A

“slow pathway”; Symbolic AI approach (cognitive BDI&E models)

Evaluation of cognitive models of emotion activation

BDI models of event
based emotions (OCC) that might be activated in a
making process (e.g. car driving, Haptek agent player)

Evaluating them in terms of sensitivity to individual parameters and of
uncertainty in the probability of emotion activation in a given condition

Extension to ‘HCI emotions’ (anxiety, frustration, satisfaction, etc); + WP3

Recognition and interpretation of emotional states

Integrating recognition of emotion (recognition methods; WP4) + (cognitive
models for) interpretation of its causes

Recognize emotional state of users in natural language interaction (corpus of
‘natural’ dialogs collected through Wizard of Oz tool; WP5, WP9)

Build model of interlocutor to interpret their possible causes (incrementally)


WP7: Emotion in Cognition and Action


WG3: Bridging the gap

The gap:

Behavioral architectures (embodied agents):

Good for low
level, pre
attentive accounts of emotion, fast reactions

BUT reactive
> subject to problems of local decision

Symbolic AI architectures (rule
based systems):

Good for high
level appraisal
based accounts of emotion (planning, rich
expectations and action sequences into the future)

BUT problems with sensor

and environment
directed (multi
task) processing,
brittle and unreceptive to changes in the world

Task of WG: integrate both types of architectures using a model of affect

Proposed work: motivation
driven continuous planner (hybrid)
architecture, extension of TABASCO

NOT another hybrid, multi
layer architecture but
critical analysis of
integration challenges


WP7: Emotion in Cognition and Action


WG4: Social cognition and interaction

Two goals:

Critical understanding of (selected) key mechanisms and key issues to take into
account social aspects in emotion
oriented agent architectures

Guidelines for integration of emotion
oriented architecture (WP7) & expressive
behaviors (WP6)

Moods and appraisal in social interaction: DFKI

based model that generates both emotions and moods based on a
configurable, subjective appraisal component, in multiple animated
conversational characters

Compute social aspects for interpersonal relationships, longer lasting affective
state: overall mood (‘morale’ vector) of group, social integrity, ‘mood groups’

Emotion in social dynamics (agent
based simulations)

Mutual support role of emotions and social norms: OFAI

Emergence of groups with different dynamics and structure: UH


WP7: Emotion in Cognition and Action


WG4: Social cognition and interaction

Automatic and low
level mechanisms in social interaction

Action model to study the role of affect in imitation of movements,
emotional contagion (synchrony, mimicry) using robots: UH

Artistic framework: synchronization and coordination of movements in dance
(humans and robots): DIST

Social attention and memory
: Paris8

General environmental attention mechanism for early social interaction; e.g.
visual attention towards faces, other features (change, movement?) WP4

Memory: autobiographical, social

Generation of socially meaningful emotional behavior

Standards for translating a cognitive process into body behavior

Definition of basic “units” that control body behavior

Take advantage of animation systems that result in realistic body animations


WP7: Emotion in Cognition and Action


Interaction with WP4

WP4 to WP7:

Signs of emotion in different modalities for different types of architectures and

WG1: signals to signs of emotions for robots (e.g. robotic “biosensors”)

WG2: emotion recognition methods for symbolic processing

WG3: signs of emotion for “fast” and “slow” processing simultaneously

WG4: focus on movement; faces?

WP7 to WP4:

Specifications on constraints imposed by different architectures and platforms
for the interpretation / processing of signs of emotion

Generalization of Markov analysis from ethology & dynamical systems theory
to data analysis (non
linearity problems); complementing it with information
theory => Rene


WP7: Emotion in Cognition and Action


Guidelines for exemplars

Informed by critical analysis of our existing models / systems / tools

Guided by analysis of needs (think ahead, goals, “visions”)

Exemplars / Exemplar: “modules” under common “umbrella”

Theoretical + pragmatic criteria, e.g. meaningful publications

Integration effort:

Within “modules”: across areas / problems / disciplines

Across “modules”: self
critical + think positive

Our scope, our limitations, what we intend to and can / cannot achieve

What others can do that I can’t, insights / know
how I could gain

What I could contribute to other “modules” and approaches

What? Goals & Tasks of WP 7


Achieve shared understanding of basic issues and basic research topics

Set the grounds to advance the state of the art

Disseminate the achieved research results and conclusions


Task 1: Integration of existing know

Task 2: Plans to advance the state of the art

Task 3: Dissemination of gained insight


WP7: Emotion in Cognition and Action


Integration effort?

Shed light towards development of sound computational models that:

Enhance behavior & interactions of emotion
oriented systems

Feed back to emotion theorists (synthetic approach)

Integrated effort (
≠ IP!!
), shared critical reflection about:

Key conceptual issues

Assumptions and dependencies

Open research problems

Key research and application scenarios

Critical analysis of existing approaches, systems and tools

Analysis of needs and directions for future research and applications

Evaluation methods, scenarios, tools

Recommendations for good practice, usability requirements

Potential for cross
fertilization among disciplines
