Infant EEG and fNIRS - What kind of questions can we address?
7 important questions on Infant EEG and fNIRS - What kind of questions can we address?
What do we measure with EEG?
Toybox ERP study:
- 8 to 11-month-old infants make visual anticipations to future actions based on statistical regularities
How do 2.5-year-old toddlers perceive feedback? -> Experiment:
50% chance
-> get feedback
-> ask again (100% predictable)
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Results of feedback experiment (lions)
Adults are faster -> peak is earlier, less variability
Infants have noisier data -> individual differences, how much do they learn from feedback
Lower frequencies when they were younger
Change in power of different frequencies
- Characterised by certain phase and amplitude
- give different frequency bands, depending on:
- condition
- extracting power
- phase
2 frequency bands of interest (FOI)
- Central alpha -> mu
- beta
What happens to the frequency bands when perform an action?
- Suppression of alpha in motor area,
- because alpha is inhibitory
OR:
- when they do not move: they are all in synchrony but when they move they go out in synchrony
Less power in mu when performing an action
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
