The HIV/AIDS pandemic continues to be a significant global public health crisis. The main HIV/AIDS treatment is the antiretroviral therapy (ART), which is highly effective but depends on the patient’s adherence to be successful. However, the adherence to antiretroviral therapy remains unsatisfactory across different populations, which raises consid...

Peer support interventions for people living with HIV and AIDS (PLWHA) are effective, but their associated time and material costs for the recipient and the health system make them reachable for only a small proportion of PLWHA. Internet-based interventions are an effective alternative for delivering psychosocial interventions for PLWHA as they are...

Objectives: COVID-19 sanitary measures (social distancing, school closures) have deeply impacted social life, support networks, and their protective role in mental health. The present study aims to understand how attachment styles influence the way individuals experience social support. Particularly, investigating its moderating role in the relatio...

Background The emergence of COVID-19 has brought global awareness to the impact of the pandemic on mental health. Public health measures such as school closures and lockdowns led to overburdening both in children and their caregivers and increased emotional and behavioral problems, especially in low-income families. More work exploring families’ re...
Article
Full-text available
Cognitive dynamics are multimodal, and they need to integrate real-time feedback to be adaptive and appropriate. However, cognition research still relies on mostly unimodal paradigms using simple motor tasks in laboratory-based static situations. This paper addresses this limitation by presenting the Mobile Brain/Body Imaging approach based on the...

Introduction: The problem of suboptimal adherence to antiretroviral treatment (ART) can be overcome through multidisciplinary management that includes evidence-based psychosocial interventions. Existing reviews focus only on randomized controlled trials, overlooking valuable interventions whose evidence comes from different study designs. This revi...

Peer support interventions for people living with HIV and AIDS (PLWHA) are widely effective, but their associated time and material costs for the recipient and the health system make them reachable for only a small proportion of PLWHA. Internet-based interventions are an effective alternative for delivering psychosocial interventions for PLWHA as t...

El desarrollo reciente de las ciencias psicológicas y cerebrales ha avanzado enormemente nuestro entendimiento del fenómeno cognitivo. Para lograr esto, el uso de experimentos de laboratorio ha sido esencial, sin embargo estos experimentos usualmente se encuentran lejanos a la experiencia vivida en el mundo real. Evidencia actual indica que una de...

TRADUCCIÓN por EILIS REARDON (Connecticut College - ereardon@conncoll.edu). Avances tecnológicos recientes englobados bajo de Mobila Brain/Body Imaging framework (Makeig et al., 2009), ha producido emocionantes nuevos resultados experimentales que vinculan el mente, el cerebro, y el comportamiento (Gramann et al., 2014; Ladouce et al., 2017; Shamay...
Article
Full-text available
Although the influence of social support in health is a widely acknowledged factor, there is a significant gap in the understanding of its role on cognition. The purpose of this systematic review was, therefore, to determine the state-of-the-art on the literature testing the association between social support and cognition. Using six databases (WoS...
Article
Full-text available
Recent technological advancements encompassed under the Mobile Brain/Body Imaging (MoBI) framework have produced exciting new experimental results linking mind, brain and behaviour. Nevertheless, novel hypotheses, measures and experimental paradigms are needed in order to tackle MoBI's ultimate goal: to model and understand cognition, behaviour and...
Preprint
Recent technological advancements encompassed under the Mobile Brain/Body Imaging (MoBI) framework, have produced exciting new experimental results linking mind, brain, and behavior. The main goal of the MoBI approach is to model brain and body dynamics during every-day, natural, real-life situations. However, even though considerable advances have...
Preprint
Recent developments in psychology and neuroscience have greatly advanced our understanding of cognition. But while classical laboratory experiments have been crucial to informing models of brain functioning, these types of experiments generally do not capture the experiences of the real world and therefore lack ecological validity. Due to the natur...
Article
Full-text available
Modern cognitive science is the outcome of a transdisciplinary effort constituting the largest body of work about the mind in human history. These advancements have guided our understanding of the functional role of the agent’s body and context when producing adaptive behaviour and interactions. Thus, cognition is embodied, embedded, extended and e...
Article
Full-text available
Exploration and play are considered to be crucial behaviors during mammalian development. Even though the relationship between glucocorticoids and exploratory behavior, stress, and anxiety is well described in the literature, very little is known about their role in play behavior in non-rodents. Likewise, the functional role of the “social hormone”...
Article
Full-text available
Oxytocin (OXT) and arginine-vasopressin (AVP) are two phylogenetically conserved neuropeptides that have been implicated in a wide range of social behaviors. Although a large body of research, ranging from rodents to humans, has reported on the effects of OXT and AVP administration on affiliative and trust behaviors, and has highlighted the genetic...

Full-text available
Biological motion stimuli represent the essence of locomotor behavior and activate two major brain systems. One system is active in mentalizing, where an individual ascribes goals and mental states to another's actions, and consists mainly of the superior temporal sulcus, medial prefrontal cortex, and amygdala. A second system, consisting of the an...
Chapter
Full-text available
In this chapter we focus on the neural processes that occur in the mature healthy human brain in response to evaluating another’s social attention. We first examine the brain’s sensitivity to gaze direction of others, social attention (as typically indicated by gaze contact), and joint attention. Brain regions such as the superior temporal sulcus (...
Article
Full-text available
Gaze direction, a cue of both social and spatial attention, is known to modulate early neural responses to faces e.g. N170. However, findings in the literature have been inconsistent, likely reflecting differences in stimulus characteristics and task requirements. Here, we investigated the effect of task on neural responses to dynamic gaze changes:...
Article
Full-text available
Our brains readily decode facial movements and changes in social attention, reflected in earlier and larger N170 event-related potentials (ERPs) to viewing gaze aversions vs. direct gaze in real faces (Puce et al., 2000). In contrast, gaze aversions in line-drawn faces do not produce these N170 differences (Rossi et al., 2014), suggesting that phys...

Reviews the book, Ancestral Landscapes in Human Evolution: Culture, Childrearing and Social Wellbeing edited by Darcia Narvaez, et al. (see record 2014-09498-000 ). This book provides an invitation to reflect on the fact that human nature is exquisitely complex. Although this complexity won’t be a surprise to any social- or life scientist, this boo...
Article
Full-text available
Our brains readily decode human movements, as shown by neural responses to face and body motion. N170 event-related potentials (ERPs) are earlier and larger to mouth opening movements relative to closing in both line-drawn and natural faces, and gaze aversions relative to direct gaze in natural faces (Puce and Perrett, 2003; Puce et al., 2000). Her...

The common history of Homo sapiens and Canis lupus familiaris dates back to between 11,000 and 32,000 years ago, when some wolves (Canis lupus) started living closely with humans. Although we cannot reach back into the past to measure the relative roles of wolves and humans in the ensuing domestication process, it was perhaps the first involving hu...
Article
The rate of pecking at seeds by Steller's jays (Cyanocitta stelleri) is affected by the type of seed that is available and the presence and activity of nearby conspecifics. Jays at an artificial feeding platform peck at a lower rate when another jay is nearby, except when the other jay is feeding at a different platform. The decreased feeding rate...
