N2  - One important organizational property of morphology is competition. Different means of expression are in conflict with each other for encoding the same grammatical function. In the current study, we examined the nature of this control mechanism by testing the formation of comparative adjectives in English during language production. Event-related brain potentials (ERPs) were recorded during cued silent production, the first study of this kind for comparative adjective formation. We specifically examined the ERP correlates of producing synthetic relative to analytic comparatives, e.g. angriervs. more angry. A frontal, bilaterally distributed, enhanced negative-going waveform for analytic comparatives (vis-a-vis synthetic ones) emerged approximately 300ms after the (silent) production cue. We argue that this ERP effect reflects a control mechanism that constrains grammatically-based computational processes (viz. more comparative formation). We also address the possibility that this particular ERP effect may belong to a family of previously observed negativities reflecting cognitive control monitoring, rather than morphological encoding processes per se.

T1  - Uninstructed BIAT faking when ego depleted or in normal state
BT  - differential effect on brain and behavior
T2  - BMC neuroscience
N2  - Background:
Deception can distort psychological tests on socially sensitive topics. Understanding the cerebral 
processes that are involved in such faking can be useful in detection and prevention of deception. Previous research 
shows that faking a brief implicit association test (BIAT ) evokes a characteristic ERP response. It is not yet known 
whether temporarily available self-control resources moderate this response. We randomly assigned 22 participants 
(15 females, 24.23
±
2.91
years old) to a counterbalanced repeated-measurements design. Participants first com-
pleted a Brief-IAT (BIAT ) on doping attitudes as a baseline measure and were then instructed to fake a negative dop
-
ing attitude both when self-control resources were depleted and non-depleted. Cerebral activity during BIAT perfor
-
mance was assessed using high-density EEG.
Results:
Compared to the baseline BIAT, event-related potentials showed a first interaction at the parietal P1, 
while significant post hoc differences were found only at the later occurring late positive potential. Here, signifi-
cantly decreased amplitudes were recorded for ‘normal’ faking, but not in the depletion condition. In source space, 
enhanced activity was found for ‘normal’ faking in the bilateral temporoparietal junction. Behaviorally, participants 
were successful in faking the BIAT successfully in both conditions.
Conclusions:
Results indicate that temporarily available self-control resources do not affect overt faking success on 
a BIAT. However, differences were found on an electrophysiological level. This indicates that while on a phenotypical 
level self-control resources play a negligible role in deliberate test faking the underlying cerebral processes are markedly different.
