Olfactory interference on the emotional processing speed of visual stimuli: The influence of facial expressions intensities.

Research on olfactory stimulation indicates that it can influence human cognition and behavior, as in the perception of facial expressions. Odors can facilitate or impair the identification of facial expressions, and apparently its hedonic valence plays an important role. However, it was also demonstrated that the presentation of happiness and disgust faces can influence the emotional appraisal of odorants, indicating a bilateral influence in this phenomenon.

A New Mental Health Mobile App for Well-Being and Stress Reduction in Working Women: Randomized Controlled Trial.

Background: Although the availability and use of mobile mental health apps has grown exponentially in recent years, little data are available regarding their efficacy.

Objective: This study aimed to evaluate the effectiveness of an app developed to promote stress management and well-being among working women compared with a control app.

Methods: Female employees at a private hospital were invited to participate in the study via mailing lists and intranet ads.

The University of São Paulo Twin Panel: Current Status and Prospects for Brazilian Twin Studies in Behavioral Research.

The University of São Paulo Twin Panel (Painel USP de Gêmeos), based at the Institute of Psychology of the University of São Paulo, started formally in 2017. Our registry is new, but in only two years of formal existence, it comprises a volunteer sample of 4826 registered individuals (98% twins and 2% higher-order multiples), recruited at the University of São Paulo and by social media campaigns. Our main aim is to conduct and promote research with twins on psychological processes and behavior.

Modulation of cerebral haemodynamic response to olfactory stimuli by emotional valence detected by functional magnetic resonance imaging.

Unlabelled: Olfactory perception, although restricted to just a few contexts in everyday life, is key in medicine. Several dementia conditions have been associated with early loss of olfactory discrimination. Despite the fact that several brain areas have been associated with olfaction in functional magnetic resonance imaging (fMRI), the mechanisms by which emotional valence is conveyed to the brain are not fully understood.
