Hi again
My own speculations regarding my previous email :)
I surfed through SPM resources and came up with the following. Please correct me if I'm wrong. For the first question I should use two-way between-subjects ANOVA (proficiency (low/high)*type of word(noun/verb). I did it in the full factorial section of the batch
and created 4 cells in the batch. Did I proceed the right steps? Only the proficiency main effect turned out significant. The interaction was not significant. Does that make sense?
For the second question, I guess I should follow the same steps mentioned in the previous question adopting another two-way between-subjects ANOVA? Since proficiency main effect was significant in the previous analysis, then I should do two separate analyses, one for low proficient bilinguals and one for high proficient bilinguals.
For the last question, I should do four different two-way ANOVAs, two for the low proficiency group and two for the
high. In the low group, first I compare bilinguals' Persian representation with that of monolinguals, and then I compare bilinguals' English representation with monolinguals' Persian representation. I do the same for the high group. Am I right in my hunches? Is there any other way so that I can reduce the number of analyses?
I highly appreciate your comments
Looking forward to reading you soon

Dear all
I am extremely confused as to what
kind of design I should adopt in my group level model specification SPM batch. Let
me clarify on the data a little bit and the questions I am seeking. I have two
groups: bilinguals (20 subjects) and monolinguals (14 subjects). The bilinguals
group is divided into two groups based on their proficiency: low and high. Bilinguals
produced English nouns, English verbs, Persian nouns, and Persian verbs in the
scanner; while, monolinguals produced only Persian nouns and verbs. Now what I
want from the data. First, I would like to determine the differences between
low proficiency and high proficiency bilinguals in the neural representation
and processing of both English nouns and verbs. Second, I would like to compare
noun and verb processing in bilinguals’ both languages. Finally, I would like
to compare Persian noun and verb processing and English noun and verb
processing in each group of bilinguals with Persian noun and verb processing in monolinguals.
What kind of design should I choose in the design section of the model
specification batch? Is that a factorial design? Should I do different analyses
for each of the mentioned questions or just one single analysis suffices? I
highly appreciate your kind comments and suggestions
Best wishes
