Summary of DamasioWhat is Emotion?

Biological, evolutionary perspective on emotion

Biologically shared mechanism of homeostasis

Emotions arise in three steps

1 Induction2 Processing3 Bodily/Brain reaction

Emotional reactions are coordinated quick, non-consciouschanges to the whole organism

This allows the organism to reliably produce complexbehaviors in important circumstances

Emotion is thus a powerful mechanism for copingw/complex environment, scarce resources & high risks

Summary of DamasioEmotions and Feeling

Emotions can happen w/o awareness of feeling

Recall the curious case of David

Emotions are felt when brain perceives reaction

Reflexivity: common idea about consciousness (Dennett,Lycan, Dretske)

According to Damasio, this also involves thecharacteristic feature of consciousness:

The perception is ‘bound to the self’

Damasio’s Slogan (From Interview)

We are not thinking machines. We are feeling machines thatthink. (http://youtu.be/Aw2yaozi0Gg)

Damasio and EmotionsImplications for Research on Emotional Machines

Emotional Machines

If Damasio is right, you can create an emotional machinew/o creating a conscious one

In building emotional machines, focus on replicatingemotional induction, processing & reaction

Suppose we really are feeling machines that think, andpart of feeling is perceiving emotional reactions

Then even to understand how cognition works, we mustsimulate the embodied emotional reactions that pervadeour interactions

Why Emotional Robots?Motivation

Okay, so emotion is relevant to this abstract questionabout whether machines could have minds

Why bother trying to build an emotional machine?

Other than that emotion is a powerful tool for adaptivebehavior (Damasio)

Cynthia Breazeal (bruh-zill) and Rosalind Picard haveprovided powerful answers to this question

Emotional RobotsThe Road Map

Human interaction relies heavily on emotion

So it provides particularly powerful space ofman-machine interactionsAnd it is a particularly important part of making robotsthat interact w/people in a compelling way

Doing this does not require building a robot that can feelits emotions, just one that has them

Induction, processing, reaction

By producing a robot w/emotional and cognitive systems,test ideas about how the two interact

Let’s look at Breazeal’s robot Kismet

So it provides particularly powerful space ofman-machine interactions

And it is a particularly important part of making robotsthat interact w/people in a compelling way

Reflecting on KismetWhy Facial Expressions

Kismet’s Expressions (Breazeal & Brooks, p.306)

“...It is certainly possible to use other information-baseddisplays to reveal the internal state of the robots: flashinglights, laser pointers, graphics, etc.

However, people wouldhave to learn how to decipher such displays to understandwhat they mean. Furthermore, information-based displays failto leverage from the socio-affective impact and intuitivemeaning that biological signals have for people.”

Reflecting on KismetThe Message

Reflecting on Kismet (Breazeal & Brooks, p.307)

“As robot builders, we shall continue to design integratedsystems for robots with internal mechanisms that complementand modulate its cognitive capabilities to improve the robot’soverall performance.

Several of these mechanisms may beclose analogs to those regulatory, signaling, biasing, and otheruseful attention, value-assessment, and prioritizationmechanisms associated with emotions in living creatures. As aconsequence, we will effectively be giving robots a system thatserves the same useful functions that emotions serve in us –no matter what we call it.”
