Hi, everyone
I make a design by the following method:
(1)blocked were used including two type of stimulus: Semantic task and Phonetic task.
(2)the control task is fixation
(3)the duration for stimulus block is 10TR(30s), the duration for control task is 7TR(21s)
(4)the sequency of those blockes are S C P C P C S C P C S C S C P C (4 block for Semantic, 4 block for Phonetic and 8 for Control)
(5)TR 3s, Total scan 136. Total duration 6min 48s
(6)the first two scan needed to removed
(7)i want to the following result: (a). S-C (b) P-C (c)(S-C)-(P-C) (d)(P-C)-(S-C)
I very appreciated if anyone can tell me how to model this design in SPM:
Pull down menu: Would you like to...
Interscan interval -
Scans per session -
Number of conditions or trials -
Condition or trial name -
Stochastic design -
SOA (Stimulus Onset Asynchrony) -
SOA (scans) for active -
First trial (scans) -
Parametric modulation -
Are these trials -
Select type of response... (PullDown) -
Convolve with HRF -
add temporal derivatives -
epoch length {scans} for active -
interactions among trials (Volterra) -
user specified regressors -
