How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The literature on social interactions has shown that participants coordinate not only at the behavioral but also at the physiological and neural levels, and that this coordination gives a temporal structure to the individual and social dynamics. However, it has not been fully explored whether such temporal patterns emerge during interpersonal coord...

It has been postulated that symmetric faces are considered more attractive than asymmetric ones because symmetry may signal high quality due to developmental stability. However, other studies showed that both symmetric and slightly asymmetric faces are considered attractive. Here we aim to explore this discrepancy, beginning with the ana...
Background:
22q11.2 deletion syndrome is a medical condition that results from genomic loss at chromosome 22. Affected patients exhibit large variability that ranges from a severe condition to mild symptoms. In addition, the spectrum of clinical features differs among populations and even within family members. The facial features related to this...
Fluctuating and directional asymmetry are aspects of morphological variation widely used to infer environmental and genetic factors affecting facial phenotypes. However, the genetic basis and environmental determinants of both asymmetry types is far from being completely known. The analysis of facial asymmetries in admixed individuals can be of hel...
One of the main challenges of forensic anthropology in the context of the current humanitarian crisis in Mexico is to provide solutions that help increase the number of human identifications. For these solutions to be effective, proposals must incentivize collaboration among diverse actors and benefit both the end users of the produced knowledge an...
Rhythmic information is an essential part of verbal and non-verbal coordination during human conversations. In small group settings, who coordinates with whom can further shape the overall coordination and create unique global rhythmic patterns qualitatively different from the individual rhythms involved. Despite their significance, the local and g...
La investigación y práctica de la antropología biológica desempeñan un papel crucial en el entendimiento de las poblaciones humanas y su diversidad biocultural. En este contexto, es fundamental fomentar dis-cusiones y reflexionar sobre la forma más apropiada de conducirnos en nuestra práctica profesional con el objetivo de garantizar un trato digno...
We present an interdisciplinary approach to the construction of facial composites that could overcome some of the cognitive limitations that are frequently found in eyewitness/forensic recognition. We take advantage of the extensive anthropological research carried out on the facial characteristics of the Mexican population that produce the CARAMEX...
Objectives:
To evaluate three of the main verbal models that have been proposed to explain the relationship between fluctuating asymmetry and fitness in humans: the "good genes," the "good development," and the "growth" hypotheses.
Materials and methods:
A formal model was generated for each verbal model following three steps. First, based on th...
Interpersonal coordination is assumed to be a complex phenomenon due to the large number of factors involved and the non-trivial way in which they interact. Temporal collective patterns may emerge during natural interactions in ways that cannot be predicted from the behavior of the participants alone. One of these patterns is the collective rhythm,...
The literature on social interactions has shown that participants coordinate not only at the behavioral but also at the physiological and neural levels, and that this coordination gives a temporal structure to the individual and to the social dynamics. However, it has not been fully explored whether such temporal patterns emerge during interpersona...
El retrato hablado es una técnica frecuentemente utilizada en la investigación policial. Sin embargo, la investigación de laboratorio indica que el nivel de identificación de un rostro, a partir de un retrato hablado, es bajo. Una de las razones de esto es que el retrato hablado tradicional no se aproxima a los procesos de reconocimiento facial hum...
The present study describe the morphological variation of a large database of facial photographs. The database comprises frontal (386 female, 764 males) and lateral (312 females, 666 males) images of Mexican individuals aged 14-69 years, that were obtained under controlled conditions. We used geometric morphometric methods and multivariate statisti...
