Chapter 6 : Attention Flashcards
What is the concept of change blindness in terms of the variable of attention?
” You may not track it, if you are not focused on it.”The door study was when people were so focused on giving them person directions that they didn’t notice when the person changed, once the door passed.There are several perceptual changes, like the door study, that we can miss a lot of changes around us. This is because we can only pay attention to a few things at a time.
What is change blindness?
We are bad at detecting changes that occur when we don’t know where to look and don’t know where to direct our attention. IN real life, we usually don’t jump back and forth between changes because something usually changes permanently. The change is not always processed.
What does attention imply in regards to energy and withdrawling things?
Attention implies that we may withdrawal some things to deal effectively with others. It is based on windows where we devote our attention at a time. Energy mya be a limited resource
The more complex and unfamiliar the task, will there be more or less resources needed to allocate to the task?
More mental resources
What is an example of selective attention and what is it?
An example is the ability to focus your attention on just one friend. It is selecting which stimuli to attend to and which one to be ignored.
Which part of the brain does attention focus on?
Chiefly the frontal lobe.
Directing attention involves directing what to relevant areas of the brain? Where would blood go for an auditory task? Reduction in blood flow explains what?
Blood flow. To the temporal lobe. Decrease in memory, capability, attention, and control of body functions as we age.
Why is there a significant increase in rCBF during the first few years of life?
This is because of the intense demand for attention, learning, and metabolism in the early stages of life.
Why is ADHD related to blood flow?
If there is lack of blood flow to important regions of the brain it can affect the function that the region of the brain is reponsible for. Reduced brain size also means reduced blood flow.
What is the function of Guanfacine? Does that decrease of increase parasympathetic or sympathetic activity?
It can treat ADHD & high blood flow, by decreasing the heart rate to allow for better blood flow. It would increase parasympathetic activity.
How is attended information treated differently than unattended information?
Different processing occurs. But we can miss extremely noticeable things that happen in front of us.
What is the downside of selective attention? What is it? What can it result in?
Inattentional Blindness. It is contradicting because people believe we may see everything, even unexpected things. It can result in missing information ( like the hat tapping test,) or unlawfully putting people in jail in the cop pursuit.
Searching for a single feature that is fast and requires little attention is what type of search?
A feature search. ( Finding red amongst green lines.)
What type of feature is slower and more complex because you are looking for a combination of features?
A conjunctive search. ( Finding vertical red amongst horizontal/vertical other colored lines.)
If our attention is elsewhere, what can happen to things we are looking directly at?
We will fail to see it and you won’t notice things you aren’t looking for.
