RESUMO

Studies on crime and parking facilities also appear to have a strong focus on car theft with small emphasis on psychological and cognitive variables to investigate potential crimes in this environment. Furthermore, there is limited literature on such crimes in South America, particularly in Brazil. This study has the objective of offering an instrument to assess risk perception in public and private parking lots of free circulation, as well as to understand and describe how individual values influence this variable regarding civilians' and police officers' perception of hazards present in free circulation public and private parking lots. A psychometrically valid risk perception and security attitude scale is presented. The scores of the two groups were predicted by human values. It was observed a mapping of risk situations in parking lots, as well as attitudes that can prevent crimes. Implications for the development of social public safety policies are discussed.

RESUMO

To investigate the neural representations of faces in primates, particularly in relation to their personal familiarity or unfamiliarity, neuronal activities were chronically recorded from the ventral portion of the anterior inferior temporal cortex (AITv) of macaque monkeys during the performance of a facial identification task using either personally familiar or unfamiliar faces as stimuli. By calculating the correlation coefficients between neuronal responses to the faces for all possible pairs of faces given in the task and then using the coefficients as neuronal population-based similarity measures between the faces in pairs, we analyzed the similarity/dissimilarity relationship between the faces, which were potentially represented by the activities of a population of the face-responsive neurons recorded in the area AITv. The results showed that, for personally familiar faces, different identities were represented by different patterns of activities of the population of AITv neurons irrespective of the view (e.g., front, 90° left, etc.), while different views were not represented independently of their facial identities, which was consistent with our previous report. In the case of personally unfamiliar faces, the faces possessing different identities but presented in the same frontal view were represented as similar, which contrasts with the results for personally familiar faces. These results, taken together, outline the neuronal representations of personally familiar and unfamiliar faces in the AITv neuronal population.

RESUMO

The anterior superior temporal sulcus (STS) of macaque monkeys is thought to be involved in the analysis of incoming perceptual information for face recognition or identification; face neurons in the anterior STS show tuning to facial views and/or gaze direction in the faces of others. Although it is well known that both the anatomical architecture and the connectivity differ between the rostral and caudal regions of the anterior STS, the functional heterogeneity of these regions is not well understood. We recorded the activity of face neurons in the anterior STS of macaque monkeys during the performance of a face identification task, and we compared the characteristics of face neuron responses in the caudal and rostral regions of the anterior STS. In the caudal region, facial views that elicited optimal responses were distributed among all views tested; the majority of face neurons responded symmetrically to right and left views. In contrast, the face neurons in the rostral region responded optimally to a single oblique view; right-left symmetry among the responses of these neurons was less evident. Modulation of the face neuron responses according to gaze direction was more evident in the rostral region. Some of the face neuron responses were specific to a certain combination of a particular facial view and a particular gaze direction, whereas others were associated with the relative spatial relationship between facial view and gaze direction. Taken together, these results indicated the existence of a functional heterogeneity within the anterior STS and suggested a plausible hierarchical organization of facial information processing.

RESUMO

To investigate the neuronal basis underlying face identification, the activity of face neurons in the anterior superior temporal sulcus (STS) and the anterior inferior temporal gyrus (ITG) of macaque monkeys was analyzed during their performance of a face-identification task. The face space was composed by the activities of face neurons during the face-identification task, based on a multidimensional scaling (MDS) method; the face space composed by the anterior STS neurons represented facial views, whereas that composed by the anterior ITG neurons represented facial identity. The temporal correlation between the behavioral reaction time of the animal and the latency of face-related neuronal responses was also analyzed. The response latency of some of the face neurons in the anterior ITG exhibited a significant correlation with the behavioral reaction time, whereas this correlation was not significant in the anterior STS. The correlation of the latency of face-related neuronal responses in the anterior ITG with the behavioral reaction time was not found to be attributed to the correlation between the response latency and the magnitude of the neuronal responses. The present results suggest that the anterior ITG is closely related to judgments of facial identity, and that the anterior STS is closely related to analyses of incoming perceptual information; face identification in monkeys might involve interactions between the two areas.
