ERP Correlates of Identity Negative Priming
Correlates of Negative Priming
Statistical Analysis of the ERPs
Procedure
systematic analysis of components
No effects found for P1 (≈ 102ms),N1 (≈ 174ms), P2(≈ 230ms) , N2 (≈ 270ms)
posterior P3 (≈ 360ms)
frontal positive slow wave (≈ 700ms)
strong priming effect on PSW peak latency, thereforeamplitude determination with individual time windows

Statistical Analysis of the ERPs
P3 Results
latency: main effect priming (p < .05)no individual significant effects
amplitude: main effect priming (p < .05)significant differences of NP, PP to CO (p < .05)
lateralization
amplitude differences for {P1, P3, P5, P7} significantlylarger than control: NP (p < .001), PP (p < .05).
no amplitude differences for {P2, P4, P6. P8}:NP (p < .22), PP (p < .11).

ERP Correlates of Identity Negative Priming
Discussion
Discussion of Experimental Results
left hemispheric reduced P300
effort of stimulus evaluation affects P300 amplitude
less effort for negative and positive priming conditionsdue to similarity of prime and probe display
result challenges inhibition based models of NP
favors episodic retrieval perspective
frontal positive slow wave
PSW amplitude reflects coordination complexity
most coordination in NP trials, least in PP-trials
episodic retrieval implies no amplitude effects NP – CO
inhibition model suggests no amplitude effects at all

ERP Correlates of Identity Negative Priming
Discussion
Conclusion
Take Home Message
finding of correlates of identity NP
lateralized smaller P300 for NP, PP
in consistence with [Stahl, Gibbons in press]
PSW reduction for NP, higher PSW for PP
Outlook
identifying sources of variance in the EEG-data
wavelet analysis for single trials
intensive data mining for identification of ERP differencese.g. classification of trials by a multilayer perceptron
