1. Facial processing in bipolar disorder is mediated by clinical and biological aspects
Objective: The process of detecting faces can be considered one of the initial steps in face recognition, which is essential for human interaction. We sought to investigate whether a face perception task reliably detects subtle perceptual disturbances between patients with bipolar disorder (BD) and healthy controls. Methods: In this multisite study, we exam

2. The ability of patients with Parkinson’s disease to recognize masked faces during the COVID-19 pandemic
RESUMO. Pacientes com doença de Parkinson (PcP) têm dificuldades de reconhecimento facial. Objetivo: Avaliamos as dificuldades de PcP em reconhecer rostos mascarados durante a pandemia de COVID-19. Métodos: Incluímos 64 PcP, 58 controles saudáveis mais velhos (CSVs) pareados por idade, 61 controles saudáveis mais jovens (CSJs) no estudo. O Benton F

3. Self-face perception: Individual differences and discrepancies associated with mental self-face representation, attractiveness and self-esteem
Self-face perception plays an important role in self-consciousness and personal identity as well as in social exchanges and well-being. Despite its significance, little is known about how individuals represent their faces internally. This study explored mechanisms of self-face perception in three experiments. First, participants chose from two images (self-f

4. Lateral visual hemifield asymmetry and sex differences in recognizing low and high spatial frequency filtered faces
The present study investigated whether low and high spatial frequency filtered images of faces were recognized differently when briefly presented in the right and the left visual fields of men and women. The method of confidence rating was applied to assess pooled Receiver Operating Characteristic curves based on z scores and the d´ parameter of Signal Dete

5. Um lugar ao sol: velhice - do reconhecimento ao exílio / A place in the sun: old age - from recognition of exile
The main objective of this research was to show the life history of the oldest former mayor of Brazil. The writings of Giddens (2002) were used to demonstrate the interference of modernity in the lives of human beings and Beauvoir (1990) and Bosi (1994) intertwine the aging, a fact that further demonstrates how the old social minorities. As Mr Susumo was Jap

6. Representação esparsa e modelo de esparsidade conjunta no reconhecimento de faces / Sparse Representation and Joint Sparsity Model in Face Recognition
O trabalho desenvolvido nesta dissertação propõe a utilização do modelo de esparsidade conjunta com complemento de matrizes (JSM-MC) para composição da base de treino no contexto de reconhecimento de faces utilizando o classificador baseado em representação esparsa (SRC). O método proposto visa trabalhar com imagens de faces em diferentes condiçõ

7. ESTUDO DE ÍNDICES DE DIVERSIDADE COMO DESCRITORES DE TEXTURA PARA CLASSIFICAÇÃO DE IMAGENS DE FACES / STUDY OF DIVERSITY INDICES AS DESCRIPTORS OF TEXTURE FOR CLASSIFICATION IMAGES OF FACES
O objeto de estudo deste trabalho é uma investigação sobre o potencial grau de caracterização de texturas de faces humanas em imagens digitais usando índices de diversidade. Para isto é desenvolvida uma metodologia que utiliza o retinex como técnica de normalização de iluminação, índices de diversidade para a extração de características e a M

8. Reconhecimento de faces com filtragens de frequências espaciais altas e baixas nos hemicampos visuais direito e esquerdo / Facial recognition in high and low spatial frequency filtering in the right and in the left hemifields
This study aimed to investigate whether face recognition occurs primarily by analytic or holistic processing in the cerebral hemispheres of men and women through the study of the spatial frequency spectrum. Therefore, in Experiment I, 40 volunteers (20 women) performed two sessions. In each of, 14 faces were memorized for a recognition task and each face was

9. A contribuição da União Europeia à governança da mudança climática global: explicando as condições para a actorness da UE
As a regional organization, the European Union's role in global climate governance faces constraints that do not apply to other members of the United Nations Framework Convention on Climate Change (UNFCCC) and Kyoto Protocol. Addressing that uniqueness, this article provides a theoretical and empirical analysis of how the elements of actorness (recognition,

10. Application of computer graphics in facial reconstruction for recognition: a case study / Aplicação da computação gráfica na reconstrução de face para reconhecimento: um estudo de caso
The facial reconstruction, also known as facial approximation, is performed for centuries by forensic medicine professionals and anthropological areas researchers. In the forensic medicine, for example, it is used when there is no evidence that allows the identification of the individual by considered accurate means, such as DNA testing or dental records. Th

11. Binding faces and names in working memory requires additional attentional resources
In this study we used the dual-task paradigm to investigate the involvement of attention in the binding of verbal and visual information in working memory. A secondary task, backward counting by threes (BCT), was performed during the retention interval of the primary recognition task based on either visual or verbal information or the binding of both. The BC

12. Effect of escitalopram on the processing of emotional faces
Serotonin has been implicated in the neurobiology of depressive and anxiety disorders, but little is known about its role in the modulation of basic emotional processing. The aim of this study was to determine the effect of the selective serotonin reuptake inhibitor, escitalopram, on the perception of facial emotional expressions. Twelve healthy male volunte
