摘要

We conducted a functional magnetic resonance imaging (fMRI) study to elucidate the neurocognitive mechanisms of harmful and helpful dishonest decisions. During scanning, the subjects read scenarios concerning events that could occur in real-life situations and were asked to decide whether to tell a lie as though they were experiencing those events. Half of the scenarios consisted of harmful stories in which the dishonest decisions could be regarded as bad lies, and the other half consisted of helpful stories in which the dishonest decisions could be regarded as good lies. In contrast to the control decision-making task, we found that the decision-making tasks that involved honesty or dishonesty recruited a network of brain regions that included the left dorsolateral prefrontal cortex. In the harmful stories, the right temporoparietal junction and the right medial frontal cortex were activated when the subjects made dishonest decisions compared with honest decisions. No region discriminated between the honest and dishonest decisions made in the helpful stories. These preliminary findings suggest that the neural basis of dishonest decisions is modulated by whether the lying serves to harm or help the target.

7. FINANCIAL INFORMATION AS A BASIS FOR MAKING DECISIONS IN LOCAL GOVERNMENT UNITS Abstract: Purpose – an attempt to determine the importance of reporting of units of territorial government in making rational decisions. Design/Methodology/Approach – the analysis of the subject literature and legal acts concerning financial reporting of units of territorial government. Findings – financial and budgetary reports made by units of territorial government contain a lot of drawbacks and do not always serve a purpose of making right decisions. Originality/Value – indication of a possibility to apply new tools that would provide accurate and solid information for management goals in units of territorial government. Keywords: information, decisions, reporting, task reporting [O] . Monika Wakuła 2015
