Hello,
A few years ago I came across the following design:
ArArArArBrBrBrB
with r being a 'baseline' condition while A and B were 'neutral'
and 'emotional' conditions, respectively (r=15 sec, A and B = 30 sec
each). The rationale of the authors was that they wanted to avoid having
condition A contaminated by condition B (assuming it could happen if a
block or blocks of B were to be placed before a block of A during a given
run).
Is there anything wrong with this design (e.g. is it susceptible to low
frequency noise? Is it sub-optimal for some other reason?).
Thank you in advance,
Sherif
