1.1. Key Concepts

1.1.1. Processing Bottom up vs. Top Down Serial vs. Parallel Also: Cascade

1.1.2. Approaches Experimental Cognitive Psych Cognitive Neuropsych Uses Associations Uses Dissassociations Computational Cognitive Science create computer programs that model human cognitive mechanisms. Cognitive Neuroscience Brain structure/function vs. cognitive processing Techniques:

1.2. Historical Perspectives

1.2.1. Introspection

1.2.2. Behaviorism

1.2.3. Cognitive Revolution Transcendental Method "Inference to best explanation"

2. Visual Perception & Object Recognition

2.1. Object Recognition

2.1.1. Approaches Bottom-Up vs. Top-Down Viewpoint-dependent vs. Viewpoint-Invariant Viewpoint-Dependent Viewpoint-Invariat examples: Greebles Where happening in the brain? :46min

2.2. Visual Perception

2.2.1. Perceptual Constency size ex: railroad tracks shape ex: opening door color

2.2.2. Perceptual Segregation Gestaltism 6 laws of P.S. Figure-Ground Segregation

2.2.3. Why important? Apply knowledge take action! Learning combining info Needed for Object Recognition Challenges

2.2.4. Awareness of a Stimulus Subjective Threshold fails to report conscious awareness Objective Threshold point at which no evidence aware of it often used as a prime falls to chance level aka Subliminal Perception


2.3.1. Recognition-By Components Theory geons as building blocks though segmentation and edge extraction viewpoint invariant -:

2.3.2. Marrs Theory of Visual Object Recognition 3 stages of processing 2D primal sketch 2.5 D sketch 3D model is made + includes both top down and bottom up specified in adequate detail to be simulated by a computer

2.3.3. NEG (-): no address how you recognize particular object rather than A object (your labtop vs a labtop) Not enough with importance of context Applies to clear parts/shapes

2.4. Deficits

2.4.1. Agnosia visual agnosia :55 apperceptive agnosia associative agnosia distinguish between the two simultagnosia Spatioal agnosia prosopagnosia human faces or holistic processing

2.4.2. Delusional MisID Capgras Fregoli Syndrome Different ppl are the same individual morphing in appearance

2.4.3. Blindsight Damage to V1, primary visual cortex Respond to visual stimuli, even though not perceiving

3. Attention and Executive Function

3.1. Definitions and Models

3.1.1. Stimulus Awareness HOW unaware? below sensory threshold sensory adaptation Habituation

3.1.2. Processing Automatic unintentional few resources parallel fast! Controlled DEF: TYPES: Auto ----> Controlled? Automatization

3.2. Impairments and Assessments

3.2.1. Deficits RHD Hallmarks How assess? Treatment approaches ADHD Types Executive Function Deficits ex: Phineas Gage TBI Stroke Developmental Disorders Neurogenerative disease TBI Attentional Deficits Executive Function Deficits Organizational Deficits Social probs Synthesis/Integration Goal Formation Frontotemporal Dementia often misdiagnosed as Alzeheimers or psych NonVerbal Learning Disorder Concrete, difficulty with abstract Poor organization Poor Social skills Poor visual discrimination good decoders, terrible at comprehension

3.2.2. Assessing Executive Function Defictis 3 behaviors to look at: Propositional Interactional Nonverbal Tasks Cancellation Mazes Clock Drawing Problem solving tasks


4.1. CLASS 5

4.1.1. TYPES working memory LTM semantic episodic perceptual representation system procedural

4.1.2. MODELS Braddeley & Hitch visuospatial sketchpad Phonological loop Central Executive Episodic buffer Levels of Processing Thry Examples rehearsed through: note....encoding/retrieval types must match!

4.1.3. Operations of Memory Encoding consolidation Storage free recall Retrival availability accessibility

4.1.4. TASKS Recall v Recognition Recall Recog Explicit v Impilicit Explicit Impliciit Retrospective v Prospective Retro Prospective

4.1.5. Forgetting WM Interference Decay

4.2. CLASS 6:

4.2.1. Neural Basis of Memory Amygdala consolidation esp. if emotional Hippocampus encoding consolidation Frontal Lobe Episodic memory Basal Ganglia and Cerebellum Skill learning Phonological store wernickes Articulatory Rehearsal left prefrontal areas say information to yourself in your head, putting it into phonological store

4.2.2. Exceptional Mnemonist Strategists Naturals

4.2.3. Disorders Amnesia loss of EXPLICIT Implicit and STM usually intact Temporal Gradient TBI Stroke Multiple Sclerosis Cerebral Tumors Alzheimer's Disease 1st sign is episodic memory then semantic nondeclarative last **loss of acetylcholine

4.3. Assessing


5.1. Types of Reps

5.1.1. concrete images=analouge codes simultanously convey info details about specific case

5.1.2. abstract symbolic codes Propositions convey info serially ability to generalize perfect for categorical info

5.1.3. Dual Coding Theory

5.2. Concepts and Categories

5.2.1. concepts fundamental unit of symbolic knowledge "mental glue" of past to present experiences allow us to: make predictions organize and rep knowledge communicate

5.2.2. cateogories

5.2.3. Stored in LTM Defining Attribute all category members are equally rep'd -: Characteristic attributes Prototype each category has a rep-ing prototype -: Exemplar final thoughts Feature based + prototype approaches?

5.2.4. Schematic Networks schemas influence how we learn concepts Semantic Networks interconnected NODES BASIC LEVEL=preferred specificity

5.2.5. Connectionist Networks reped by the PATTERN of activation aka Parallel Distributed Processing (PDP) models



7.1. Language and Thought

7.1.1. Properties: Arbitrary Symbolic Regularly structured at mulitple levels! Generative Dynamic ex: Beowolf

7.1.2. Components Form Syntax Morphology Phonology Content Semantics Use Pragmatics Deep vs. Surface Structure Surface Deep Prosody

7.1.3. Whorfian Hypothesis can lang influence... Color perception/memory spatial relationships

7.2. Bilingualism
