Lecture 9 Flashcards
Cognitive Control
What is cognitive control?
Physiological processes contributing to planning, controlling and regulating information flow
Where is the prefrontal cortex?
The frontal cortex without the motor cortex
What makes up the prefrontal cortex?
Dorsolateral, orbitofrontal, ventrolateral and medial prefrontal cortices as well as the anterior cingulate cortex
What part of Phineas Gage’s PFC was damaged?
Mainly orbitofrontal cortex
What are delay cells?
Cells firing during delay, are keeping rules in working memory
Is the PFC involved in memory?
Yes, people with damage to the PFC have worse working memory
What is the n-back test?
Tests working memory, press button when stimulus appears and have certain rules + lures
What does dorsolateral PFC activation correlate to?
Better working memory, less likely to respond to lures, so maybe is suppressing non-relevant information
Also better at tower of London test
What is the tower of London test?
Balls on sticks and have to make certain arrangement in as little moves as possible
What is self-control?
Suppressing highly reinforced behaviours
What is the hot system?
Governed by emotions, do what you want. Reflexive and fast and develops early
What is the cold system?
Governed by logic, do what is best. Slow and reflective, develops later
What is utilisation behavior?
Behaviour triggered by stimulus e.g put glasses on. Often done by people with PFC damage
What is the Wisconsin sorting task?
Card matches one card of list depending on one feature and after a while the rule changes.
How do people with PFC damage do in the Wisconsin sorting task?
Have trouble changing to new rule and will continue with old rule over and over
