“…Researchers have found that low current brain stimulation potentially can be used to enhance: high level cognitive functions [2]; memory [5,6] and sensory functions [7]. Sela and Lavidor [8] defined an enhancement as "an intervention that improves a subsystem in some way other than repairing something that was damaged or remedying a specific dysfunction" (p. 300). tDCS also has been used to correct a deficit or problem [9] but our focus in this study was on cognitive enhancement.…”

“…I will therefore focus on two areas, working memory (WM) and numerical cognition, as examples of such abilities. The interested reader is referred to the recent review by Sela and Lavidor (2014), which covers studies of additional capacities like language, problem-solving, memory and cognitive control.…”

A new line of research opens the possibility of modulating and enhancing human cognition using mild and painless transcranial electrical stimulation (tES), which includes transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS). Such initial findings trigger excitement as well as scepticism. The current review aims to provide a guideline for those who are interested in expanding their research into this field. I will therefore discuss: (1) the principles of tES and its putative mechanisms; (2) its potential to modulate and enhance cognitive abilities; (3) the misconceptions on which scepticism about this method is based; and (4) possible directions for the advancement of this field in which psychologists in general and cognitive psychologists in particular should in my view play a key role. I will conclude that this nascent field, which has been neglected by psychologists, requires their contribution in order to lead to basic and translational advancements on human behaviour.

“…tDCS applies electrical stimulation to a specific area of the brain to either depolarize or hyperpolarize the neurons in that area (Sela & Lavidor, 2014). Depolarization, resulting from anodal stimulation, makes neurons fire more easily, and hyperpolarization, re-sulting from cathodal stimulation, means that the neurons are less easily excited (Sela & Lavidor, 2014). tDCS is preferable over TMS when the target brain region is large (e.g., DLPFC), and tDCS is generally a cheaper and easier method for research than TMS (Filmer, Dux, & Mattingley, 2014).…”

Researchers debate whether domain-general cognitive control supports bilingual language control through brain regions such as the dorsolateral prefrontal cortex (DLPFC). Transcranial direct current stimulation (tDCS) is a method to alter brain activity, which can lead to causal attribution of task performance to regional brain activity. The current study examined whether the DLPFC enables domain-general control for between-language switching and nonlinguistic switching and whether the control enabled by DLPFC differs between bilinguals and monolinguals. tDCS was applied to the DLPFC of bilingual and monolingual young adults before they performed linguistic and nonlinguistic switching measures. For bilinguals, left DLPFC stimulation selectively worsened nonlinguistic switching, but not within-language switching. Left DLPFC stimulation also resulted in higher overall accuracy on bilingual picture-naming. These findings suggest that language control and cognitive control are distinct processes in relation to the left DLPFC. The left DLPFC may aid bilingual language control, but stimulating it does not benefit nonlinguistic control.
