Members,
I am looking for assistance in interpreting results of a study. It
involved the testing of three different music practicing conditions. I
performed a GLM-repeated measures with three factors (modeling,
self-listening, self-evaluation) in addition to a repeated measure
(test). There was a significant interaction for test x modeling x
self-evaluation. There was also a significant result for test x
modeling. Does the higher-order interaction negate the results the
"main effects" or lower-order interaction?
Specifically, musicians who listened to "model" performance improved
their performance more than those that did not listen to a model.
Great. For the interaction (test x modeling x self-evaluation), the
modeling/self-evaluation group improved more than did the no
modeling/self-evaluation group (reinforcing the results for modeling
only). HOWEVER, the same result did not occur for the groups that did
not self-evaluate. They improved similarly to each other.
So...listening to a model is more effective than not listening to one
when there is no-self-evaluation.
What then does this mean as far as the results for the test x modeling
result? I guess my question is does a higher-level interaction
"overrule" a lower-level interaction?
I appreciate your help!
TIA
