Human biological and cultural evolution is tied to the relationships established with other animals. Attachment is one of the mechanisms established between dogs/cats and humans and allows the generation of affective bonds and close proximity. Many instruments have been used to study attachment of people to their dogs/cats, such as the Lexington Attachment to Pets Scale (LAPS). Our aim was adapting LAPS for South American populations (Brazil, Arg…
Monozygotic twin sisters differ in voice quality
Identical twins challenge individual voice recognition applied in communication, criminal investigation, and health technologies. The similarities between siblings are due to the genetic heritage that produced either their vocal tract or the psychological processes acting since birth. To contribute to a precise individual identification by voice, we tested the hypothesis that even MZ siblings would differ in the spectral distribution of formants …
Well-Being and Personality as a Function of Genetic and Environmental Influences
Subjective well-being (SWB) has been a growing focus of research internationally. Personality is one of the most important predictors of SWB. The interaction between SWB and personality is explained by a genetic component responsible for individual differences. Individual differences are a product of complex processes involving genetic and environmental factors, estimated through twin studies. The present study aims to estimate the genetic and en…
What's in a Name
The current paper investigates the intra-pair similarity of twins’ first names in comparison to non-twin siblings. The dataset was composed of 2,387 pairs of Brazilian names of same-sex individuals as a function of sex, age ( 18 years), and self-reported zygosity (MZ: Monozygotic vs DZ: Dizygotic). We assigned scores to each pair of names according to a classification system of 12 categories of intra-pair similarity (0 = absent; and 1 = present).…

The majority of the sample lived in the Southeast (61.8%) or in the South (24.5%) of Brazil. We conducted a Multilevel Confirmatory Factor Analy…
Face Scanning in Autism Spectrum Disorder and Attention Deficit/Hyperactivity Disorder
This study used eye tracking to explore attention allocation to human and dog faces in children and adolescents with autism spectrum disorder (ASD), attention deficit/hyperactivity disorder (ADHD), and typical development (TD). Significant differences were found among the three groups. TD participants looked longer at the eyes than ASD and ADHD ones, irrespective of the faces presented. In spite of this difference, groups were similar in that the…

Razão, emoção e ação em cena
O conhecimento científico da mente humana tem avançado desde a fundação da Psicologia. Aspectos biológicos e culturais, psicológicos e neurológicos, emocionais e racionais foram privilegiados separadamente em diferentes épocas e perspectivas - a visão de mente foi por vezes focalizada e por vezes relegada à caixa preta da ciência psicológica. Contemporaneamente, assiste-se a buscas de integração entre mente e comportamento humanos. A mente é vist…
