dc.description.abstract | Transcranial direct current stimulation (tDCS) has become a valuable tool in cognitive neuroscience
research as it enables causal inferences about neural underpinnings of cognition. However,
studies using tDCS to modulate cognitive functions often yield inconsistent findings. Hence, there
is an increasing interest in factors that may moderate the effects, one of which is the participants’
beliefs of the tDCS condition (i.e., real or sham) they received. Namely, whether participants’ correct
guessing of sham condition may lead to false-positive tDCS effects. In this study, we aimed to
explore if participants’ beliefs about received stimulation type (i.e., the success of blinding) impacted
their task performance in tDCS experiments on associative (AM) and working memory (WM).We
analyzed data from four within-subject, sham-controlled tDCS memory experiments (N = 83) to
check if the correct end-of-study guess of sham condition moderated tDCS effects. We found no
evidence that sham guessing moderated post-tDCS memory performance in experiments in which
tDCS effects were observed as well as in experiments that showed null effects of tDCS. The results
suggest that the correct sham guessing (i.e., placebo-like effect) is unlikely to influence the results in
tDCS memory experiments. We discuss the results in light of the growing debate about the relevance
and effectiveness of blinding in brain stimulation research. | sr |
