Project sheet
of the three kinds of systems, this and goal-based are cognitive systems, reflexive isn?t

Activity

complicated architecture of putting together modules

An agent is a system that ?perceives? its environment through reason and acts upon that environment through effects

Does something
That comes back and alters environment

3 kinds of systems

reflex systems directly connect the sensors and effectors in a fixed way

what it does to inputs is always the same
EX-iPod
EX-old-fashioned thermostat
EX-varilax lenses (change to sunglasses in the sun)

EX-iPod

Push skip, and it always skips to the next track

EX-old-fashioned thermostat

When it senses the temp. drop, the circuit closes and it affects environment by turning on the heat

EX-varilax lenses (change to sunglasses in the sun)

Senses sun and change into sunglasses

of the three kinds of systems, this and goal-based are cognitive systems, reflexive isn?t

Ex. of reflex system
Give one example of a goal-based system
1 EX of Learning systems
give 1 EX of a cognitive module
*See Ch. 10* (Q uine?)

Ex. of reflex system

Security system
Dead snake bite (reflexive)
Parking meter

Give one example of a goal-based system

Goal-based agent examines the consequences of various actions and chooses the one that will xent achieve the agents goals.
Have internal representational states!!
Makes a straight-forward decision on what to do
WHAT DRIVES IT? Is it environment? Is it input-output
EX-(not humans)

1 EX of Learning systems

learning agents compare feedback from the outputs and a performance standard to change outcomes and improves performance

EX-(not humans)

Roomba (robotic vaccum)
Automated chess player
GPS

learning agents compare feedback from the outputs and a performance standard to change outcomes and improves performance

EX- cruise control on car

Representation of current speed & of desired speed (standard)
Constantly comparing the two speeds

give 1 EX of a cognitive module

Fodor?s Modularity Thesis ? the mind at the level of information processing is composed of modular agents
4 characteristics of cog. Module
EX of module ? color detection
WHAT HAS ALL FOUR FEATURES? Test your knowledge of the modular system thesis

4 characteristics of cog. Module

system to count as module has to be oriented w/ a specific task (ex. cruise control speed, iPod play music)
operation is usually not effected by other tasks going on in mind
not a reflex, but at the level of information processing

EX of module ? color detection

Domain specific (color apparatus is only for color and not other tasks, ex. defining edges)
Protected functions
fast application ? automatic, happen really fast

*See Ch. 10* (Q uine?)

language processing
George Washington was the first president of the US

If your math test was in colors, you could still detect the colors of the words regardless of what they are

Argument against ? Stroop Effect ? reading the word of the color; cog. Processing of language is disrupted by things

EX ? facial recognition

That?s something hard to describe
You find that it?s difficult to even think of your mental representation of them

fast application ? automatic, happen really fast

Classical AI is not good at

Fodor?s Modularity Thesis

? the mind at the level of information processing is composed of modular agents

George Washington was the first president of the US

To understand sentence, need to refer to an enormous number of other sentences whose meaning is linked to this sentence
Unit of meaning is not a word or sentence, but a larger body of sentences bearing on the meaning of it
EX-need a large amt of other sentences to describe George Washington

Domain specific

(color apparatus is only for color and not other tasks, ex.

Protected functions

- If your math test was in colors, you could still detect the colors of the words regardless of what they are

Automatically implemented

? is pretty easy to detect color, don?t have to think about it

fast application

? automatic, happen really fast

WHAT HAS ALL FOUR FEATURES

Test your knowledge of the modular system thesis
