    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.
