learning Flashcards
types of learning
conscious (facts and events)
non-conscious (implicit, non-declarative) aka riding a bike
perceptual learning
one form of skill learning.
training-induced improvements in the ability to perform a perceptual task
“Perceptual Skills (Like Threshold) Can Improve with Practice
- Should this be surprising? I think not – think learning a musical “
Applications of perceptual learning
Practical
—rehab (teach to be better musician)
—creating new expertise (being a musician)
Theoretical
—neural processing ***
—learning mechanism (what causes the brain to change)
duration discrimination
(trained, untrained freq, untrained durations)
{part of neural processing}
Cares about duration not freq. Trains certain neurons…for example neurons that respond to 100ms….those really start to like things at 100ms. But they don’t care about things at 200 ms. This shows that the system cares about duration. It doesn’t generalize across the board…in this example it gets trained at 100ms not 200ms and 300ms etc. trained-learning untrained freq-generalization untrained duration-no generalization
learning mechanism
Perceptual learning typically requires performance of the task to be learned.
need for task performance
- Lack of cross-task transfer
- Smaller or no physiological changes when stimulus exposures are not linked to task performance
frequency discrimination
Adjust freq difference until they cant tell it apart anymore.
We want to look at if there is learning? How would you tell if there is learning? The freq difference would get smaller/youd be sensitive to smaller and smaller differences.
does interval discrimination aid frequency discrimination?
no. just being exposed to stimuli doesn’t drive anything. youre approach towards the stimulus is what drives it.
task performance to frequency
The idea is that task performance has some special function. Top down (cognitive issues that go and look at lower level processing).
Task performance helps you select neurons that are important for you (not only select, but they get the neurons in a state that they’re ready to be changed);Sufficient stimulation of the sensitized neural processes leads to lasting modification
number of training trials/day
Additional daily training beyond the required amount does not enhance learning
what drives learning?
Only amplified responses contribute to learning; Lasting learning occurs if there is sufficient amplified stimulation
time constraints of the sensitized state
-Provide too few training trials to yield learning
-Add periods of additional stimulus exposure
