Comparisons
Attention Theories Comparison
Theory | Description | Key Findings |
|---|---|---|
Broadbent’s Filter Theory | Early selection based on physical traits | Does not explain Cocktail Party Effect |
Treisman’s Attenuation Theory | Unattended info is weakened, not blocked | Explains why we still notice important info |
Late-Selection Theory | All information is processed for meaning | Unattended stimuli can influence behavior |
Capacity Model (Kahneman) | Attention is a resource allocated flexibly | High arousal increases cognitive resources |
Feature Integration Theory | Perception occurs in two stages | Attention is needed to bind object features |
Memory Models Comparison
Model | Description | Key Findings |
|---|---|---|
Modal Model (Atkinson & Shiffrin) | Information moves through sensory, STM, and LTM | STM is limited in capacity and duration |
Working Memory (Baddeley) | Active processing system with multiple components | Involves phonological loop, visuospatial sketchpad, and central executive |
Levels of Processing (Craik & Lockhart) | Deeper processing leads to better retention | Semantic processing improves memory |
Memory Processes Comparison
Process | Description | Key Findings |
|---|---|---|
Levels-of-Processing | Deeper encoding leads to better memory | Semantic processing enhances recall |
Encoding Specificity | Retrieval improves when conditions match encoding | Context-dependent learning is effective |
Reconstructive Memory | Memories are actively rebuilt, not exact copies | Schema-driven errors occur in recall |
Flashbulb Memories | Vivid, emotional event memories | May be distorted over time |
