5 important questions on Fundamentals of Cognition - PowerPoint
How does the Baddeley and Hitch working memory model look?
- Baddeley and Hitch
- Central executive, mental workspace for complex tasks and control of behavior
- Coordinates, controls, diversity, unity
- Updating, Shifting, Inhibition
- Visuospatial Sketchpad: maintain and manipulate visual information, spatial insight, mental rotation
- Phonological Loop: speech sounds 2.5 sec (EN: 6.6 words, Fin: 5.8 words)
What is updating, inhibition and shifting
- Pictures 1, black screen, picture 1 or 2 -> same or different? Black screen, new face -> same or different
- Simon-effect (incongruent response-stimulus location)
- Stroop Effect
- Stop Signal
- Wisconsing Card Sorting Task
- Longer reaction time, lower accuracy
What are .. Of Long-term memory?
Explicit: conscious, (cued) recall, recognition
Implicit: unconscious, familiarity, procedural
Three stages:
- Encoding
- Existing schema's
- Elaboration
- Yerkes Dodson Law
- Storage
- Interference
- Decay
- Retrieval
- Spontaneous recall (57%)
- Cued recall (67%)
- Recognition (83%)
- Forgetting due to:
- Insufficient encoding
- Decay/interference in retrieval
- Insufficient cues
- Induced forgetting
- Reconsolidation
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are strategies for decision making?
- Low effort, fast but sloppy
- Bias
- Improves with experience
Normative models
- Best decision, accurate but slow
- Algorithms: rules, operators
What is the role of emotion in decision making?
(1) People differ in emotional (body state) awareness
(2) Better awareness → better decision making (Iowa Gambling Task)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
