Abstract

Objective We investigated the hypothesis that rimonabant, a cannabinoid antagonist/inverse agonist, would increase anxiety in healthy subjects during a simulation of the public speaking test.

Abstract

O objetivo dessa pesquisa foi gerar, por meio de técnica de computação gráfica denominada morphing, faces prototípicas masculinas e femininas a partir de amostras de pessoas que se autodeclaram brancas, pardas e pretas na região de Ribeirão Preto (SP). A cada face prototípica foram utilizadas 64 imagens de faces de voluntários. As faces prototípicas e as faces que as compuseram tiveram a tipicidade de sua cor ou raça julgada por terceiros. Os julgamentos indicaram uma concordância entre a cor/raça-autodeclarada e a heteroatribuída o que indica que os protótipos são representativos de suas respectivas categorias de cor/raça. Discute-se como as faces prototípicas podem ser empregadas em pesquisas básicas e aplicadas em percepção e reconhecimento de faces.

Abstract

Objective: The aim of the present study was to analyze the body sway response in specific phobia (SP) patients and healthy controls while viewing neutral, phobic, and disgusting images. Methods: The participants’ heart rate (HR) and skin conductance were also recorded during the procedure. Nineteen patients with arachnophobia and 19 healthy volunteers matched by age, gender, and years of education underwent a postural control test on a stabilometric platform. Results: The platform recorded increased body sway in the SP group when exposed to spider images (SPI). The SP group presented increases in most parameters (SD, velocity, frequency, area, p ≤ 0.05) when viewing pictures of the SPI category. Psychometric measures of subjective anxiety (State-Trait Anxiety Inventory, STAI) and physiological states (HR; skin conductance responses; spontaneous fluctuations in skin conductance) showed increased anxiety (p ≤ 0.05) in the SP group compared to healthy volunteers. High anxiety levels were observed throughout the assessment, including the task of exposure to SPI (p ≤ 0.05). No significant effect or correlation was found between skin conductance and body sway measures (p > 0.05). Conclusions: The results of the postural control test suggest the occurrence of a defensive escape response in SP, in agreement with previous evidence.
