Week 8 H9 Flashcards
What does the Mental schema theory by Norman and Shallice describe?
The theory describes routine and non-routine automatic processes and how schemas for routine actions are activated or inhibited.
In the context of the Mental schema theory, what determines the selection of a routine action?
The contention scheduling (CS) chooses the strongest schema to perform the routine action.
What role does the supervisory attentional system (SAS) play in non-routine actions according to Norman and Shallice?
The SAS inhibits routine schema selection and switches to an approach requiring executive functions.

Define Multimodal working memory model by Baddeley and Hitch.
It describes three models of working memory: Phonological loop, Visuospatial sketchpad and episodic buffer are directed by the Central executive.

The shielding-shifting dilemma in executive functioning involves what two main aspects?
It involves protecting goal against distraction (shielding) and adapting to the goal (shifting).
In the shielding-shifting dilemma, what factor often causes a shift towards flexibility over stability?
A positive state often leads to more flexibility.
What potential flaw exists in the unitary view of executive functions?
The flaw is the risk of developing an endless hierarchy of executive functions.

How does the criticism of fractionation approach relate to specific brain areas?
The criticism highlights that not every brain area that gets activated while performing a task necessarily controls that task.
Is there a hierarchy in the way nodes in the network handle executive processes?
No, in the current belief, there’s no hierarchy; any node in the network can be in control and can be controlled by others.
How do the unitary and fractional views on executive functions connect?
executive functions can be broken down into distinct components (fractional view),
but
these components do not operate in isolation but are highly integrated and coordinated by higher-level cognitive control processes (unitary view).
Match the following fronto-subcortical networks with their importance:
1First network
2Second network
3Third network
a. Important for motivation and can lead to apathy if damaged.
b. Important for planning and problem solving.
c. Important for social-cognitive behavioral functions and can lead to personality changes if damaged.

According to Spreng, what role does the frontoparietal control network (FPCN) play?
The frontoparietal control network monitors the balance between the dorsal attentional network (DAN) and the default mode network (DMN), particularly when an external task needs to be performed.
What are the two basic attention networks identified by Corbetta et al.?
The dorsal attentional network (DAN) and the right hemisphere ventral attentional network (VAN)/salience network.
Which brain areas does the dorsal attentional network (DAN) specifically involve?
The DAN involves the intraparietal sulcus and the frontal eye fields in both cerebral hemispheres.
