Last-in/ First-out principle |
data storage mechanism in which the most recently stored input in a memory register must also be the first to be removed from that register. Applies to attentional development. Sensory operations develop first and cognitive operations over time. as we age, the order in which they are developed will most likely be the order they go as well. |
|
|
which is developed first, cortical or subcortical brain areas? |
subcortical |
|
|
What are some obstacles that researchers face when studying children? |
1. subjects are too young to understand experimental instructions 2. subjects are not content to sit still for very long or to participate in an experiment without distraction |
|
|
how to researchers overcome the obstacles faced when studying children? |
they must make inferences about attentional processing primarily on the basis of overt orienting responses |
|
|
studies of visual orienting of infants typically involve....? |
1. the use of sudden external events as stimuli 2. sufficient novelty of these events so that subjects do not habituate to their onset |
|
|
What replaces the central fixation point in some experiments with infants? |
a toy appears through an opening in the chamber to act as a fixation point |
|
|
Why are children "unable" to voluntarily shift their attention in response to symbolic cues? |
1. young subjects are unable to understand the instructions they must follow to perform the task 2. voluntary symbolic cue use appears to involve cognitive operations that are not fully developed |
|
|
How does the Stroop effect differ with children and adults? Why does this difference occur? |
it is more pronounced with children than with adult subjects. children are less able to filter out the irrelevant information |
|
|
Why is sugar the worst for you? |
increases inflammation in the body (including the brain!), making your body work in over drive. and can make you insulin resistant (pre-diabetic) |
|
|
Why are vegetables so good for you? |
|
|
|
why is diet important for brain health? |
