Cognitive Control Flashcards
What is cognitive control?
One exerts cognitive control when they consciously control a task. This one is pretty self-explanatory, and I don’t know how to better say it.
Three types of inhibition tasks featured in the lecture are…
antisaccades, go/no-go tasks, and countermanding.
Antisaccade Task
An antisaccade task involves moving eyes away from a presented stimulus. We did this in class.
Go/No-Go Tasks
In the example in class, the black circle after a break meant press a button. A black square meant DO NOT press the button. Participants were trying to go fast, so it was naturally VERY HARD to not press the durn button.
Countermanding Tasks
The countermanding example from class occurred when participants looked at a fixation point and were told to make saccades to places, but cancel the saccade if the fixation point reappeared.
What are the 2 classes of FEF neurons?
The 2 classes of FEF neurons are saccade neurons and fixation neurons.
Race Model (of Saccade Neurons)
Suggests that Go and Stop signals race to reach a threshold that determines which will prevail and whether or not the thing will happen.
SSRT
Stop Signal Reaction Time
Which brain region really helps inhibition?
Right PFC really helps in inhibition. Check this, people.
Which brain region helps tilt the race in favor of the inhibitory signals?
The Supplementary Eye Fields hold the inhibitory control signals and also monitor the performance of the subject post-trial.
Which brain area helps tell the Supplementary Eye Fields the rules by which the
The Dorsolateral Prefrontal Cortex (DLPFC)!!!
Gratton Effect
An incompatible trial will have greater successful recognition after an incompatible trial than a compatible trial.
