POWERPOINT 2 How does a production system reduce the homunculus problem What is the homunculus problem 7 Model can t make decisions Production systems 7 Decision making done by i Without 7 Are production systems really scienti c theories or human behavior Good ones because 7 tested against experimental data from people 7 Re ned until t human data well What human data do prod systems t 7 Answers time steps Strengths amp weaknesses 7 Good for analyticconscious thinking 7 Bad for automaticunconscious thinking PDP Models PDP Parallel Distributed Processing Good explanation of 7 Unconscious automatic cognition Connectionist models 7 m Networks of Nodes Connected by links Links vary in strength More activation goes through a stronger link 7 Operation mental activation owing through network Closer to ne grained brain neurophysiology than production systems 7 Nodes represent neurons cell body or groups of neurons 7 Links represent axons connections Output Activation Moses Noah Connection Weights Input Activation The Bible What cognitive processes can the connectionist model explain 7 Recognizing words from text 7 Learning rules for forming pasttense of words eg jumpOjumped goOwent Connectionist Model Production Systems Format Activation owing in Symbols in memory buffers networks transformed by rules Works best for Automatic unconscious Analytic conscious Processes processes Limitations Can t explain some ignores automatic analytic reasoning processes Hybrid model may be best COGNITIVE NEUROSCIENCE One general method in cognitive neuroscience is 7 Identify speci c brain locations for speci c cognitive functions 7 Eg attending to a location in space done in posterior attention network 7 How did we discover this We deiscovered this by the tools on the following slide METHODS OF CORELLATING COGNITION AND BRAINS time spatial scale resolution invasive Positron emission 30s precise yes tomography PET Functional magnetic 05s precise no resonance imaging fMRI Eventrelated OOls very coarse no potential ERP LAB We can miss things that are very obvious because of focal or focused attention where we are focusing on other things and we don t notice big things Inattentional blindness is when we see the things happening we aren t actually blind to it but since we didn t attend to it in our mind we were blind to it How can knowing the brain locations of cognitive function help us understand cognition Example 7 Step 1 know initial visual retinal input to the occipital cortex is retinoptically mapped ie cortex copies spatial pattern on retina 7 Step 2 This tells us how initial visual info is represented in occipital cortex ie cortex copies spatial pattern on retina 7 Step 3 know other cog functions also located in initial occipital cortex Eg mental imagery Hypothesize these cog functions also involve spatial representation 2 Broad Types of Intentional Processes Distributed Focused selective attention Automatic conscious ControlledConscious amp Unconscious Distributed and focused attention work together on most things however For simple arti cial tasks in studies Distributed OR focused might predominate 2 Types of Tasks where distributed and focused attention are used Perceptualmotor tasks 7 perception action eg visual search auditory shadowing steering Auditory tasks eg dichotic listening i 7 Cocktailparty effect focus on 1 conversation ignore another Evidence for focusing can follow conversation Evidence for ignoring don t notice change in language in unattended ear What visual attention effect is this like Inattentional blindness Central tasks 7 Higherlevel cognition eg decsion making 7 multitasking eg driving talking Distributed Focused 1 selective atth Parallel Serial simultaneous processing lbyl processing Bottomup Topdown stimulus directed goal directed Automatic Controlled little effort parallel hard serial Unconscious Unconscious amp conscious some processes unconsc end product is conscious Focused Attention Characteristics Characteristics Serial Focusing amp ignoring Bene t Recognition of conscious object Cost 7 Ignoring potentially useful info 7 Topdown processing ie search guided by Focused Attention Examples Inattentional blindness 7 Person change task What noticed change 7 0 7 Flicker task TeXt What kind changes easier to nd in icker task 7 Task relevant changes 7 This shows focused attention is goaldirected Topdown processing Inattentional blindness 7 Gorilla demo Matlin what noticed gorilla 7 overall 54 7 If focus on white shirts 0 7 7 If focus on black shirts 0 7 7 Shows focused attention can be guided by 7 Distributed Attention Characteristics Characteristics 7 Parallel 7 Bottomup processing stunykys durected Process features of stimuli feature integ theoryi Attention capture stimuli interrupt s focused attn and cause it to focus on that stimuli hey watch me brings a stimuli into focused attention How do we know attn capture is PARALLEL Single Feature Search Much easier to nd Conjunction Search Harder to find 1 For the 2 targetpresent conditions which shows a set size effect WH Y 7 2 Why does it take longer to respond for the targetabsent than targetpresent conditions Feature Integration Theog Recognized object 0 in WM Serial attention 0 assembles features into 1 object Parallel processing 0 of indep features stimulus 0
