Stephen,
The Tests of Within-Subjects effects Greenhouse-Geisser is significant .040 and Huynh-Feldt is
significant .027 for the MOVES*IAC interaction.
The Tests of Within Subjects Contrasts indicates a significant cubic effect (.039) for MOVES*IAC.
So yes.

Paul,
Do you have a significant interaction between MOVES and IAC (i.e., is there
evidence that the slope of the within-subject factor varies as a function of
the between-subject factor)?
Best,

Subject: repeated measures custom contrasts for linear trends
Hi,
I have a customer with a within-subject factor (MOVES) with 10 levels and a
between subject factor
with 3 levels (IAC).
He wants to test if there is a linear trend at each of the 3 between subject
factor levels.
What would be the syntax for this?
I currently have the syntax below:
GLM
moves1 moves2 moves3 moves4 moves5 moves6 moves7 moves8 moves9 moves10 BY
iac
/WSFACTOR = trial 10 Polynomial
/METHOD = SSTYPE(3)
/EMMEANS = TABLES(iac) COMPARE ADJ(BONFERRONI)
/EMMEANS = TABLES(trial) COMPARE ADJ(BONFERRONI)
/EMMEANS = TABLES(iac*trial) COMPARE(iac) ADJ(bonferroni)
/EMMEANS = TABLES(iac*trial) COMPARE(trial) ADJ(bonferroni)
/PRINT = DESCRIPTIVE
/CRITERIA = ALPHA(.05)
/WSDESIGN = trial
/DESIGN = iac .
Thanks,
Paul
