Study Notes
Chapter 1: History of Cognitive Psychology
- Cognitive psychology studies human intelligence and its workings.
- Cognition is mental activity, including acquiring, storing, transforming, and using knowledge.
- Wundt studied behavior, mental processes, and perception, emphasizing public testing, explanation, and replication of research findings.
- Ebbinghaus researched memory, using the "method of savings" to study forgetting over time, particularly the forgetting curve.
- James proposed functionalism, contrasting with structuralism (focusing solely on observable components), and identified two parts of memory.
- Thorndike, Watson, and Skinner championed behaviorism.
- Gestalt psychology opposed behaviorism.
- Bartlett's work contributed to cognitive neuroscience, exploring how cognitive processes are related to brain structure and function.
- Neuroscience may pinpoint where a process occurs, but not necessarily how it happens. Techniques range from invasive to non-invasive.
Chapter 2: Visual Recognition
- Perception involves recognizing, organizing, and interpreting sensory input.
- Perception, including labels and distinctions, results from a combination of learned and innate processes.
- Percepts are mental representations of perceived stimuli, which may differ from reality.
From Sensation to Perception
- Cues: Monocular cues (one eye) include texture gradient, linear perspective (depth/distance), relative size, and interposition.
- Binocular cues (both eyes) include convergence and disparity.
Perceptual Consistencies
- Size, shape, and brightness constancy allow consistent perception despite changing sensory input.
Gestalt Principles of Organization
- Principles of figure-ground, proximity, similarity, closure, continuity, and connectedness describe how we group visual elements.
Theoretical Approaches to Perception
- Pattern Recognition
- Template Matching: Comparing sensory input to stored templates; impractical due to vast variation in object forms.
- Feature Analysis: Identifying distinctive features of stimuli and their presence or absence to recognize patterns.
- Recognition by Components (RBC): Breaking down objects into geons (geometric ions) for recognition, more accurate for brief presentations.
Object Recognition
- Presentation Rates:
- Shorter presentation times (65-100ms) favor geon-based recognition (component deletion effects).
- Longer presentation times (200ms) favor midsegment-type deletions.
Top-Down Processing
- Higher-level mental processes (e.g., knowledge, experience) influence object recognition.
- Examples include the word superiority effect, better letter recognition within a word context.
- Top-down processing is important in situations like texting and driving, where relevant information is prioritized.
Inattentional and Change Blindness
- Inattentional blindness: Failing to notice a salient visible object while attending to something else.
- Change blindness: Failing to detect changes in a scene or object.
Bottom-Up Processing
- Object recognition based solely on sensory input features.
- Crucial for face perception, which differs across individuals.
Face Perception and Deficits
- Prosopagnosia: Inability to recognize faces due to brain region damage.
- Agnosia: Difficulty perceiving sensory information.
- Visual agnosia: Difficulty recognizing objects despite sufficient visual input; varying severities.
- Simultagnosia: Difficulty paying attention to more than one object at a time.
- Spatial agnosia: Difficulty navigating due to impaired spatial reasoning.
- Associative agnosia: Difficulty applying visual perception to naming objects.
- Color agnosia: Inability to name colors despite understanding color differences.
Color Perception
- Types of color blindness include monochromacy and dichromacy, such as red-green color blindness (deuteranopia, protanopia, tritanopia).
Chapter 3: Attention
- Attention combines concentration and focalization, which are selective.
- Divided attention involves attending to multiple tasks simultaneously; selective attention focuses on a specific task.
- Dichotic listening demonstrates selective attention, as subjects preferentially pay attention to one channel.
- The Stroop effect illustrates difficulties in task conflict, such as naming colors. Incongruent (color words in different color) tasks display longer reaction times.
- Other research indicates automatic processes (like recall) and interfering processes impact attention, exemplified by tasks like driving.
- Bottle Neck Theories: Broadbent's filter theory, Treisman's attenuation theory, and Deutsch & Deutsch's late filter theory (late-selection) describe models of attentional filtration.
- Attention Theories: Schneider & Shiffrin (1977) explored automatic processing vs. controlled processing related to attention.
- Feature Integration Theory describes how we combine features to form perceptions (distributed vs. focused attention).
Adaptation and Habituation
- Adaptation: Changes in sensory and perceptual responses to continuous stimuli.
- Habituation: Reduced responsiveness to repeated stimuli. Habituation can be controlled and influenced by stimulus variation and frequency of exposure.
- Dishabituation: Restoration of attention to a previously habituated stimulus.
Chapter 4: Working Memory
- Working memory involves temporary storage and manipulation of information.
- Miller's concept of "chunking" improves memory span.
- The Brown-Peterson task and the serial position effect indicate primacy of early items and recency of last items.
- The Atkinson-Shiffrin model provides a framework for memory.
Baddeley's Working Memory Model
- Working memory comprises independent components; important for understanding the multitasking capabilities of the human mind.
- The central executive (CE) coordinates tasks, including suppression and language.
- The phonological loop handles verbal information.
- The visuo-spatial sketchpad handles visual and spatial information.
- The episodic buffer integrates info from various sources for processing (e.g., visuo-spatial sketchpad and phonological loop) into a cohesive whole.
Neuroscience of Working Memory
- Frontal lobe activity is higher during complex executive functions.
- PET scans and other techniques reveal brain regions associated with working memory processes.
Working Memory Deficits
- Damage to the frontal lobes can impair working memory functions.
