Sentation of detailed instructions for the participants. Every participant was provided a map and written directions, and also the whole team received a tablet having a specific GPS application based around the Geocaching technique. The entire team was asked to search for two characters, 2 caches and to complete 3 tasks. Creativity and accuracy had been assessed, no matter how extended it took them to finish the gameplay. On the other hand, the NS-398 participants have been also informed that the score obtained by every single team would only partly influence their probabilities for the final individual economic reward. The principle competition would demand answering questions regarding the details on the game individually, for the duration of an fMRI experiment. In this way, all the members of the group had been encouraged to acquire effectively involved inside the game and bear in mind as a lot as you possibly can. There have been two characters engaged within the game and waiting in the park for the teams to describe their tasks and to answer any attainable queries. When all tasks had been completed the teams had been asked to come back for the Nencki Institute exactly where they were introduced for the approach of MR information acquisition and presented with all security regulations. Also, each and every participant completed an MRI security screening questionnaire plus the scanning sessions were scheduled for precisely the same day. Each and every session was 
preceded by a conversation with an experimenter, IS. Inside a separate room, participants have been given a list of concerns regarding the particulars on the game and asked to answer truthfully. Then, they had been offered the guidelines (S Text) of an upcoming interrogation. Getting totally truthful was treated as an proof of cooperation together with the interrogator and assured a low financial reward (around 3EUR). Concealing the details from the game guaranteed receiving a high economic reward (approximately 60EUR). Nevertheless, the interrogator had already received two sources of data: the forms that they completed online and also the lists of queries concerning the game that they had just completed. They had been instructed to provide true answers to these queries to produce the interrogator trust them. Subsequently, they have been provided a further list of queries which had not been offered for the interrogator. The experimenter discussed all the unclear queries PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/22393123 with all the participants and pointed out that the inquiries received by the interrogator formed quite a few subject categories. This way, the participants could quickly keep in mind once they had been supposed to tell the truth. Ultimately, the participants have been left alone for 0 minutes to compare two groups of inquiries and pick out the preferable strategy. Throughout a functional scanning sequence, the participants saw precisely the same guidelines around the screen. They had been asked 20 inquiries which they had already recognized. A few of these queries have been autobiographical (primarily based around the on-line types), other folks addressed their witness status (eg. Have you observed . . .), or their participant experience (e.g. Have you taken part . . .). Queries have been displayed until the answer yes no was given by pressing the button, but no longer than 6s. The questions had been separated by an interstimulus interval of two.5s. Behavioral strategy calculation. There had been a number of criteria for classifying the concerns in Experiment two. The initial criterion was associated to regardless of whether the question addressed the events throughout the locationbased game inside a witness or participant function. The third alternative here was autobiographical questions for which the participants were supposed to respond honestly; th.
