  1. Processing lexical semantic and syntactic information in first and second language: evidence form German and Russian S. Ruschemeyer, C. Fiebach, V. Kemp, and A. Frederici. Presented by A. Gusicova for Psych 526

  2. Purpose: • Neural networks comparison between two typologically different languages ( semantic and syntactic) German and Russian • Native (German) and non-native (German L2 Russian L1) semantic and syntactic processing

  3. Experiment 1 • Participants • 18 native German speakers (8 men; mean age 25; age range 23-30) • 7 native Russian speakers (3 men; mean age 30.5; range 23-32) • Ai Leen: Gender proportions

  4. Scott: Russian materials caused ELAN only for dlya. Ai Leen: non word after dlya. Materials

  5. Procedure: • German • 2 lists 240 items 48 per condition • Repetitions of the same participle separated by at least 20 trials • No more than three consecutive sentences belonged to the same conditionNo more then 4 consecutive trials contained either correct or incorrect sentences • 8 s each ( 0, 400, 800, 1200ms) • Russian • 200 items 40 per condition • Repetitions of a participle and null-event never occurred • No more than 3 consecutive sentences belonged to the same condition • No more then 4 consecutive trials contained either correct or incorrect sentences • 10 s each ( 0, 500, 1, 000, and 1,500ms)

  6. fMRI: • 8 axial slices 5mm thickness, 2 mm interslice distance, 64x64 data matrix 3mmx3mm inplane resolution 3T Bruker Medspec 30/100 system. • T1-weighted modified driven equilibrium Fourier transform images nonslice-selective inversion pulse followed by a single excitation of each slice.

  7. Note: Look at the accuracy rates for Russian native speakers on the correct condition Results:

  8. Bonnie: what does it mean to have decreased activation as a result of anomaly (posterior cingulate and inferior precuneus regions) ? Results: cont

  9. Results: cont

  10. Results: Cont

  11. Experiment 2: • Participants • 18 native speakers of German ( same as in Exp 1) • 14 Russian native speakers learners of German • Note: no independent measure of proficiency was reported

  12. Results:

  13. Results:

  14. Results: cont

  15. conclusions • Neural networks engaged in native speakers of typologically different languages process semantic and syntactic information are similar. • Non-native speakers rely on different areas of neural networks then native speakers while processing semantic and syntactic information.
