“…Another will be to determine how the neural mechanisms underlying these functional aspects of effort relate to those giving rise to the subjective experience of effort (Kurzban et al 2013). On these and other fronts, the project of translating effort into neural terms may benefit from the application of causal neural techniques available for human research, such as transcranial magnetic stimulation and transcranial direct current stimulation, approaches that are becoming more widely utilized in studies of cognitive control and motivation (Reinhart & Woodman 2014, Sarkis et al 2014.…”

Research on cognitive control and executive function has long recognized the relevance of motivational factors. Recently, however, the topic has come increasingly to center stage, with a surge of new studies examining the interface of motivation and cognitive control. In the present article we survey research situated at this interface, considering work from cognitive and social psychology and behavioral economics, but with a particular focus on neuroscience research. We organize existing findings into three core areas, considering them in the light of currently vying theoretical perspectives. Based on the accumulated evidence, we advocate for a view of control function that treats it as a domain of reward-based decision making. More broadly, we argue that neuroscientific evidence plays a critical role in understanding the mechanisms by which motivation and cognitive control interact. Opportunities for further cross-fertilization between behavioral and neuroscientific research are highlighted.

“…30-60 min). Consequently, typical wash-out times in cross-over studies range from 1 -7 days (for reviews see (Sarkis, Kaur, & Camprodon, 2014;Stagg & Nitsche, 2011). While HD-tDCS effects on motor evoked potentials may be stronger and slightly delayed compared with conventional tDCS (Kuo et al 2013), no significant neurophysiological effects were found beyond 120 min after the end of the stimulation for HD-tDCS as well.…”

Dissociable Roles Within the Social Brain for Self–Other Processing: A HD-tDCS Study

Theories of right temporoparietal junction (rTPJ) function in social cognition include self–other distinction, self-inhibition, or embodied rotation, whereas the dorsomedial prefrontal cortex (dmPFC) is associated with integrating social information. However, no study has provided causal evidence for dissociable roles of the rTPJ and dmPFC in social cognition. A total of 52 healthy young adults were stratified to receive either dmPFC or rTPJ anodal high-definition transcranial direct current stimulation (HD-tDCS) in a sham-controlled, double-blinded, repeated measures design. Self–other processing was assessed across implicit and explicit level 1 (line-of-sight) and level 2 (mental rotation) visual perspective taking (VPT) tasks, and self–other effects on memory. DmPFC stimulation selectively increased the influence of the allocentric perspective during egocentric perspective taking, indexed by an increase in congruency effect across explicit VPT tasks. Moreover, dmPFC stimulation removed the self-reference effect in episodic memory by increasing the recognition of other and decreasing the recognition of self-encoded words. Stimulation of the rTPJ resulted in improved inhibition of the egocentric-perspective during level 2 VPT only, indexed by a reduction of the congruency effect when taking the allocentric perspective. This research supports theories suggesting that the rTPJ facilitates embodied mental rotation of the self into an alternate perspective, whereas the dmPFC integrates social information relevant to self-directed processes.

Background: Social interaction relies on the integration and distinction of self and other. The dorsomedial prefrontal cortex (dmPFC) and the right temporoparietal junction (rTPJ) are two regions consistently associated with social processes. Theories of rTPJ function in social cognition include self--other distinction, self--inhibition, or embodied mental rotation, whereas the dmPFC is associated with a wide range of social functions involving understanding and encoding information pertaining to others. However, to date, no study has provided causal evidence for dissociable roles of the rTPJ and dmPFC in social cognition. Method: 52 healthy young adults were stratified into two studies and received either dmPFC or rTPJ anodal HD--tDCS in a sham--controlled, double--blinded, repeated measures design. Subjects completed a social cognitive battery measuring self--other processing across an implicit and explicit level one (line--of--sight) and level two (mental rotation) visual perspective taking tasks (VPT), as well as self and other encoding effects on episodic memory in order to test the self--reference effect (SRE). Results: Stimulation of the dmPFC selectively enhanced integration of the other perspective into self as indexed by an increase in congruency effect (incongruent--congruent) across both explicit VPT tasks. It also removed the SRE in episodic memory, indexed by increasing the recognition of other--encoded words and reducing the recognition of self--encoded words. Stimulation of the rTPJ resulted in improved inhibition of the self--perspective during level two VPT only, as indexed by a reduction of the congruency effect when taking the other perspective. Conclusion: Our results provide the first causal evidence for dissociable roles of the dmPFC and rTPJ in social cognition. This research supports theories suggesting that rTPJ facilitates embodied mental rotation, whereas the dmPFC integrates information relevant to the other into that of the self.
