Direct linkMelinger, Alissa; Abdel Rahman, Rasha – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2013
In this study, we present 3 picture-word interference (PWI) experiments designed to investigate whether lexical selection processes are competitive. We focus on semantic associative relations, which should interfere according to competitive models but not according to certain noncompetitive models. In a modified version of the PWI paradigm,…

Aristei, Sabrina; Melinger, Alissa; Abdel Rahman, Rasha – Journal of Cognitive Neuroscience, 2011
In this study, we investigated semantic context effects in language production with event-related brain potentials, extracted from the ongoing EEG recorded during overt speech production. We combined the picture-word interference paradigm and the semantic blocking paradigm to investigate the temporal dynamics and functional loci of semantic…

Wirth, Miranka; Abdel Rahman, Rasha; Kuenecke, Janina; Koenig, Thomas; Horn, Helge; Sommer, Werner; Dierks, Thomas – Neuropsychologia, 2011
Excitatory anodal transcranial direct current stimulation (A-tDCS) over the left dorsal prefrontal cortex (DPFC) has been shown to improve language production. The present study examined neurophysiological underpinnings of this effect. In a single-blinded within-subject design, we traced effects of A-tDCS compared to sham stimulation over the left…
