In this study, we investigated brain activity under social pressure using Solomon Asch's experimental paradigm. We replicated the group situation using the MORI technique and recorded the brain activity using functional near-infrared spectroscopy (fNIRS). Eight Japanese healthy males in groups of four participated in this study. The Asch experiment can be replicated without using confederates using MORI technique. The subject assessed with fNIRS was seated in a fixed position and assigned to answer third. A multichannel fNIRS system was used to measure the changes in the concentrations of oxy-hemoglobin (oxy-Hb) and deoxy-hemoglobin (deoxy-Hb). Nine optodes consisting of 12 channels were placed over the prefrontal cortex (PFC) of each hemisphere. In the behavioral data, the error rate (%) for the judgment tasks increased to 39.7% under the group pressure conditions, while it was 3.2% under the control conditions. Comparing the group pressure and control conditions in the fNIRS data, a difference in the increasing rate of oxy-Hb in the frontal pole (ch02, 05, 13 & 15) was observed. Therefore, we found that the frontal pole was activated when the subject felt social pressure under group situations.

Studies of geographic profiling (GP) have generally investigated the efficacy of two categories of GP strategies for predicting an offender’s base. These strategies can be classified as follows: (a) spatial distribution strategies, assessed by center of the circle hypothesis, mean center, median center, and the center of minimum distance, and (b) probability distance strategies, assessed by linear, negative exponential, logarithmic, and lognormal distributions. GP strategies were compared based on the data of 333 residential burglars who had committed at least three offenses in the Tohoku region during the years 2004-2013. Search area (total area that is searched before locating the offender’s base) was utilized as an index for accuracy measure. The results demonstrated that probability distance strategies are more accurate than spatial distribution strategies. We conclude that this is because probability distance strategies captured crime patterns of residential burglars more precisely than spatial distribution strategies.
