The ability to learn sequential contingencies of actions for predicting future outcomes is indispensable for flexible behavior in many daily decision-making contexts. It remains open whether such ability may be enhanced by transcranial direct current stimulation. The present study combined tDCS with functional near-infrared spectroscopy to investigate potential tDCS-induced effects on sequential decision-making and the neural mechanisms underlying such modulations. Offline tDCS and sham stimulation were applied over the left and right dorsolateral prefrontal cortex in young male adults in a (...) double-blind between-subject design using a three-state Markov decision task. The results showed an enhanced dlPFC hemodynamic response during the acquisition of sequential state transitions that is consistent with the findings from a previous functional magnetic resonance imaging study; a tDCS-induced increase of the hemodynamic response in the dlPFC, but without accompanying performance-enhancing effects at the behavioral level; and a greater tDCS-induced upregulation of hemodynamic responses in the delayed reward condition that seems to be associated with faster decision speed. Taken together, these findings provide empirical evidence for fNIRS as a suitable method for investigating hemodynamic correlates of sequential decision-making as well as functional brain correlates underlying tDCS-induced modulation. Future research with larger sample sizes for carrying out subgroup analysis is necessary in order to decipher interindividual differences in tDCS-induced effects on sequential decision-making process at the behavioral and brain levels.

Previous research indicates that students in engineering self-report cheating in college at higher rates than those in most other disciplines. Prior work also suggests that participation in one deviant behavior is a reasonable predictor of future deviant behavior. This combination of factors leads to a situation where engineering students who frequently participate in academic dishonesty are more likely to make unethical decisions in professional practice. To investigate this scenario, we propose the hypotheses that (1) there are similarities in the decision-making (...) processes used by engineering students when considering whether or not to participate in academic and professional dishonesty, and (2) prior academic dishonesty by engineering students is an indicator of future decisions to act dishonestly. Our sample consisted of undergraduate engineering students from two technically-oriented private universities. As a group, the sample reported working full-time an average of six months per year as professionals in addition to attending classes during the remaining six months. This combination of both academic and professional experience provides a sample of students who are experienced in both settings. Responses to open-ended questions on an exploratory survey indicate that students identify common themes in describing both temptations to cheat or to violate workplace policies and factors which caused them to hesitate in acting unethically, thus supporting our first hypothesis and laying the foundation for future surveys having forced-choice responses. As indicated by the responses to forced-choice questions for the engineering students surveyed, there is a relationship between self-reported rates of cheating in high school and decisions to cheat in college and to violate workplace policies; supporting our second hypothesis. Thus, this exploratory study demonstrates connections between decision-making about both academic and professional dishonesty. If better understood, these connections could lead to practical approaches for encouraging ethical behavior in the academic setting, which might then influence future ethical decision-making in workplace settings.
