Neuro 201 # 3 Wrap-up

Results of brain imaging studies depend on

• the number of participants

• the technique used

• the experimental design

When using neuroimaging techniques with infants, we need to take into account some factors, such as

• tolerance of the technique by infants

• resolution of the response recorded (temporal or spatial)

• duration of the experiment

• age of the infants

To answer a research question about language development, we could use only neuroimaging techniques

• YES

• NO

Neuroimaging techniques inform about what infants perceive

• YES

• NO

• not entirely

Brain imaging techniques are objective measures meaning that the interpretations of the results are unquestionable

• YES

• NO

With infants we can use behavioral psychophysics paradigm to measure perceptual thresholds and performance to detect a stimulus

• YES

• NO

• don't know

Young infants usually show worse auditory thresholds than adults, this could relate to

• immaturity of the auditory system (perceptual factors)

• different attentional processes (cognitive factors)

• the difficulty to record infants' responses (techniques)
