Study Notes

Definition and Differentiation of Cognitive Psychology

Cognitive psychology studies mental processes and human cognition through cognitive tasks.
Cognitive neuropsychology examines brain function by studying individuals with brain damage.
Cognitive neuroscience integrates brain evidence with behavioral data to understand cognition.
Computational cognitive science models human cognitive processes using computer algorithms.

Distinction from Previous Approaches

Cognitive psychology differs from behaviorism, which focuses solely on stimuli and responses, ignoring mediational processes.
Cognitive psychology examines internal processes between stimulus and response.

Information Processing Models

The brain/mind is likened to a computer, processing stimuli into perceptions and cognitive actions leading to decisions.

Processing Types

Bottom-up Processing: Direct processing based solely on sensory input.
Top-down Processing: Influenced by prior knowledge, expectations, or goals.
Serial Processing: One cognitive process occurs at a time; each must finish before starting the next.
Parallel Processing: Multiple cognitive processes occur simultaneously.

Limitations of Cognitive Psychology

Concerns regarding ecological validity, questioning the real-world applicability of findings.
Experimenter bias can skew participants' behaviors, influencing results.

Assumptions of Cognitive Neuropsychology

Modularity: The brain comprises independently functioning modules.
Domain Specificity: Each module serves a specific cognitive purpose.
Anatomical Modularity: Modules correspond to certain brain areas.
Uniformity of Functional Architecture: Assumes brain modules are similarly organized across individuals.
Substantivity: Injuries to a module impair its function without creating new functions.

Utility of Dissociations

Single Dissociations: Evidence that two tasks rely on different cognitive modules.
Double Dissociations: Confirm separate cognitive functions are processed in distinct modules.
Associations: Impairment across tasks may suggest shared cognitive functions within the same module.

Brain Lobes Overview

Parietal Lobe: Top and back of the brain, involved in sensory processing.
Frontal Lobe: Front of the brain, associated with reasoning and decision-making.
Occipital Lobe: Back of the brain, responsible for visual processing.
Temporal Lobe: Side of the brain, involved in memory and auditory processing.

Neuroimaging Techniques

Spatial Resolution: Ability to determine where brain activity occurs.
Temporal Resolution: Ability to measure when brain activity occurs.
EEG: High temporal resolution, poor spatial resolution.
MEG: Good spatial and temporal resolution.
PET: Decent spatial, poor temporal resolution.
MRI: Good structural imaging.
fMRI: Measures BOLD signals; good spatial, moderate temporal resolution.
TMS: Non-invasive technique affecting brain activity temporally.

Converging Operations

Different methodologies reaching the same conclusions increase confidence in findings.
Discrepancies signify the need for further research and theoretical refinement.

Visual Processing: Rods and Cones

Rods: Handle low light and motion; located in the periphery.
Cones: Responsible for color and detail; concentrated in the fovea.
Retinal ganglion cells transmit signals through the optic nerves to visual processing areas.

Visual Pathways

M Pathway: Processes movement, primarily from rods.
P Pathway: Processes color and fine detail, mainly from cones.
Dorsal Pathway: Deals with spatial awareness, faster processing.
Ventral Pathway: Focuses on object identity and detail.

Dual Process Theory

Suggests color perception relies on trichromatic processing followed by opponent process theory.
Three cone types: short (blue), medium (green), and long (red) wavelengths.

Visual Recognition Conditions

Prosopagnosia: Impairment in face recognition.
Achromatopsia: Absence of color perception.
Akinetopsia: Impaired motion perception.
Optic Ataxia: Difficulty with visually guided movements.
Visual Form Agnosia: Severe shape perception issues.
Dichromacy: Missing one type of cone affects color vision.
Object Agnosia: Difficulty recognizing objects despite intact intelligence.

Distinction Between Recognition Types

Pattern Recognition: Identifying two-dimensional patterns.
Object Recognition: Identifying three-dimensional objects.

Gestalt Psychology Laws

Explore organization of complex visual stimuli.
Law of Pragnanz: Stimuli are perceived in the simplest form.
Law of Proximity: Elements close together are perceived as grouped.
Law of Similarity: Similar elements are grouped.

Object Recognition Theories

Two-Systems Model: Object recognition primarily occurs in the ventral stream, global processing involves the dorsal stream.
Recognition-by-Components Theory: Objects are recognized by their basic shapes (geons) and combinations.

Holistic vs. Configural Processing

Holistic Processing: Integrating information from the entire object.
Configural Processing: Integrating information from individual parts.
Face-inversion effect: Inverted faces are harder to recognize due to more holistic processing.
Part-whole effect: Better recognition of face parts when integrated as a whole.

Fusiform Face Area (FFA)

Located in the ventral temporal cortex, specialized for face processing.
Activates during face recognition tasks.

Expertise

Involves advanced knowledge and skills in a specific area, achieved through extensive practice.

Bruce and Young Model for Face Processing

Initial face detection, followed by structural encoding, then recognition of attributes like emotion and gender or retrieving face memories.
