What is executive attention
|
Selective attention that typically acts on the contents of working memory and directs processing to achieve a goal.-multiple processes operating on representations- chess when you attend to various pieces
|
|
What are the 5 processes of executive processes?
|
1. executive attention2. switching executive attention from one activit to another3. ignoring or inhibiting information already percieved4. scheduling a sequence of activities.5. monitoring performance- how are you doing with the boiling pot?
|
|
What are executive processes?
|
Processes that modulate the operation of otehr porcesses and coordinate mental activity for a particular goal.
|
|
What is closed head injury
|
Injury caused by an external bump that does not pierce the skull. -Gages injury changed his behavior drastically.- he had lost all the abilities to organize and control his cognitive abilities.
|
|
What is frontal lobe syndrome and what does it entail?
|
Anterior damage in the prefrontal cortex-breakdown of executive processes, such as inability to appreciate oneself, inability to juggle different life responsibilites and loss of ability to put activities into motion to achieve a goal.
|
|
What is the frontal executive process?
|
Conceptual framework for thinking that all executive processes are alike in critical ways- top down processing on other neural stuctures, including perception of objects.
|
|
What is the point of the stroop test?
|
Tell us how executive processes work by looking at attentional functioning . normal patients can get correct answers on compatible and incompatible tirals, but it takes longer- attention and inhibition are involed together
|
|
What is Wisconsin Card Sort task and waht does it test?
|
Test of frontal-lobe damage- four cards are arrayed in front of the participant each with a design of colors and symbols- there is no difference in normal patients and those with damage other than that of switching attention.
|
|
What is another test that looks at testing executive fuction based on the prefrontal cortex?
|
Tower of Hanoi Problem- must move some disks, while ignoring others and swtich attention between mental move and updating working memory
|
|
What is a stimulus-response compatibility and what process is it under.
|
It is under executive attention and means the measure of the degree to which the assignment of the correct response to a stimulus is how you would normally expect people to act.
|
|
What happens when you have two stimuli that that are incompatible?
|
It requires more time and must attend to relevant information, and inhibit the automatic connection, such as pushing button with right hand when hear sound in left ear.
|
|
Explain how information flows
|
Only in upward direction with three layers, input layer, hidden layer, and the response layer (Cohen)
|
|
What is considered automatic in the stroop test?
|
Reading a certain color that is written in any color- response node for the color WORD will usually be activated
|
|
What is the role of the attentional controller?
|
CONTAINS AN indication of the current goal and activates to nodes relevant to that goal, so when we need to name color, it activates all the color nodes in teh hidden layers so that their responses are stronger than what we would typically expect
|
|
What is the conflict monitor and what does it do?
|
Monitors conflict between the nodes at the response level and as conflict increases, the monitor engages executive attion on the needed outcome.
