dear all, I have remarked something strange, with which you could possibly help in interpretation. I study bilinguals in first (L1) and second (L2) language during a verb generation task. I perform within-group analyses by using an anova. I compared several (sub)groups of L1 > L2 and L2 > L1.Only one particular group showed significant activation in L1 > L2. which is strange, because you would expect - if any - activations in L2 > L1. So, to double check I took a look at the 1 sampled T test of each group seperately. I supposed that these activations found in the comparison could be either (1) actual activations of L1 or (2) deactivated clusters in L2. None of the clusters could retrieved in the one-sampled-T-test of L1, but all four in the deactivation contrast of the 1-sampled-T-test of L2. 1- am I correct in supposing that these deactivations in L2 cause the activations in L1 > L2? 2- how to interpret these "deactivations": I realise that they can be interpreted as variations in the baseline/default activation of the brain. So that if the brain becomes "active", deactivations occur in unrelevant areas. However, the areas I have got are not all "unrelevant" to a language task (right VLPFC, left SMA, Right STG, and R dorsal motor/premotor) any help is greatly appreciated! kind regards kat -- _______________________________________ Katrien Mondt Prospective Research for Brussels BHG - RBC Vakgroep Taal- en Letterkunde Faculteit Letteren & Wijsbegeerte Vrije Universiteit Brussel Pleinlaan 2 1050 Brussel tel: 00 32 2 629 2668 fax: 00 32 2 629 3684 [log in to unmask] www.vub.ac.be/DITO www.vub.ac.be/SGER _______________________________________
