social recognition

Tobias Engl, Martin Kaltenpoth
Covering: up to 2018Pheromones serve as chemical signals between individuals of the same species and play important roles for mate localization and mate choice as well as other social interactions in insects. A growing body of literature indicates that microbial symbionts can modulate their hosts' chemical profiles, mate choice decisions and social behavior. This modulation can occur by the direct biosynthesis of pheromone components or the provisioning of precursors, or through general changes in the metabolite pool of the host and its resource allocation into pheromone production...

Elevated levels of the type III (III) isoforms of neuregulin 1 (NRG1) have been observed in the brains of schizophrenia patients that carry NRG1 HapICE risk alleles, which is thought to contribute to the aetiology of the disease. We generated transgenic mice with forebrain driven Nrg1 III overexpression (Nrg1 III tg) and previously found that male heterozygous Nrg1 type III tg mice exhibit several schizophrenia-relevant behaviours including social and cognitive deficits as well as impaired sensorimotor gating...

We investigated the effect of auditory noise added to speech on patterns of looking at faces in 40 toddlers. We hypothesised that noise would increase the difficulty of processing speech, making children allocate more attention to the mouth of the speaker to gain visual speech cues from mouth movements. We also hypothesised that this shift would cause a decrease in fixation time to the eyes, potentially decreasing the ability to monitor gaze. We found that adding noise increased the number of fixations to the mouth area, at the price of a decreased number of fixations to the eyes...

A rapid review of gray literature from 2015 to 2016 was conducted to identify the lessons learned for emergency risk communication from recent outbreaks of Ebola, Zika, and yellow fever. Gray literature databases and key websites were searched and requests for documents were posted to expert networks. A total of 83 documents met inclusion criteria, 68 of which are cited in this report. This article focuses on the 3 questions, out of 12 posed by World Health Organization as part of a Guideline development process, dealing most directly with communicating risk during health emergencies: community engagement, trust building, and social media...

Chemical communication is fundamental to success in social insect colonies. Species-, colony-, and caste-specific blends of cuticular hydrocarbons (CHCs) and other chemicals have been well documented as pheromones, mediating important behavioral and physiological aspects of social insects. More specifically, royal pheromones used by queens (and kings in termites) enable workers to recognize and care for these vital individuals and maintain the reproductive division of labor. In termites, however, no royal-recognition pheromones have been identified to date...

Understanding the neurobiological mechanisms underlying the response to an acute stressor may provide novel insights into successful stress-coping strategies. Acute behavioral stress-effects may be restricted to a specific time window early after stress-induction. However, existing behavioral test batteries typically span multiple days or even weeks, limiting the feasibility for a broad behavioral analysis following acute stress. Here, we designed a novel comprehensive behavioral test battery in male mice that assesses multiple behavioral dimensions within a sufficiently brief time window to capture acute stress-effects and its temporal profile...

BACKGROUND: Subjective wellbeing can be defined in terms of good mental state, including positive and negative evaluations that people make of their affect and lives. The aim of this study was to identify specific domains of wellbeing that are salient to Palestinian teachers living in three different contexts (West Bank, Gaza Strip, and Israel) and to map how components of subjective wellbeing vary between the three cohorts. METHODS: Data were gathered from interviews of teachers participating in 16 focus groups and from 36 key informants (including psychologists, counsellors, school principals, lawyers)...

To understand how cognitive dysfunction contributes to social cognitive deficits in depression, we investigated the relationship between executive function and social cognitive performance in adolescents and young adults during current and remitted depression, compared to healthy controls. Social cognition and executive function were measured in 179 students (61 healthy controls and 118 patients with depression; Mage = 20.60 years; SDage = 3.82 years). Hierarchical regression models were employed within each group (healthy controls, remitted depression, current depression) to examine the nature of associations between cognitive measures...

Autism spectrum disorder (ASD) and autism-like traits are associated with deficits in face memory ability, although it is not yet clear whether this deficit reflects a specific aspect of the ASD/autism-like phenotype. We addressed this issue using a neurotypical sample of adolescent twins (Ncomplete pairs  = 782) drawn from the Twins Early Development Study who were assessed on face and object memory performance alongside two core aspects of autism-like traits: (i) difficulties with social behavior/interactions, and (ii) attention to detail...

There is ongoing recognition that a wide array of social, economic, and environmental factors influence individuals' opportunities to engage in health care and healthy behaviors. Despite spending $34 billion annually on the care of patients with end-stage renal disease, the American public and nephrology community remain remarkably complacent about addressing "upstream" factors that influence the prevention, progression, and treatment of chronic kidney diseases. Recently, a growing number of health plans and dialysis providers have begun to embrace population health management; accept greater accountability for health, health care, and health costs; and envision kidney health beyond their traditional roles in care delivery...

BACKGROUND: The association between Executive Function (EF) and Theory of Mind (ToM) in autism spectrum disorder (ASD) has been mainly investigated using false belief tasks, whilst less is known about the EF effect on other ToM facets. Furthermore, the role EF plays in social communication in ASD is mainly assessed using parent-report EF ratings rather than direct assessment. AIMS: The aim of this study was to shed more light on the effect of performance-based EF measures on ToM and social communication in middle childhood in ASD relative to neurotypical controls...

The biochemical and behavioral responses to prenatal and early postnatal exposure to paracetamol in rats are not well understood. The effect of daily maternal and early life administration of 5 mg/kg (group P5) or 15 mg/kg paracetamol (group P15) was evaluated in two-month old male rats, relative to control animals receiving tap water (Con). Social behavior and episodic memory were investigated with Social Interaction and Novel Object Recognition (NOR) tests. Quantification of brain-derived neurotrophic factor (BDNF) was determined in prefrontal cortex, hippocampus and striatum using enzyme-linked immunosorbent assay (ELISA)...

The factors that trigger the pathophysiology of Parkinson's disease (PD) are unknown. However, it is suggested that environmental factors, such as exposure to pesticides, play an important role, in addition to genetic predisposition and aging. Early signs of PD can appear in the gastrointestinal (GI) tract and in the olfactory system, preceding the onset of motor impairments by many years. The present study assessed the effects of oral rotenone administration (30 mg/kg) in inducing GI and olfactory dysfunctions associated with PD in mice...

The recognition of mental health needs in developing countries is growing in parallel with increased public awareness of and reduced stigma toward mental illness. With resources still limited in these countries, creating economically viable health care models is essential. These models are often adapted from already established and tested systems in industrialized nations. The Psychosis Recovery Outreach Program (PROP) at the American University of Beirut is an initiative that exemplifies the global transfer of knowledge, experience, and skills...

The recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions (Experiment 1) as well as differently-valenced emotions (Experiment 2) conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence for a context effect on accuracy only in Experiment 1...

Social isolation (SI) during adolescence may induce schizophrenia-like behavior. In the present study, we investigated whether adolescent SI might affect the development of schizophrenia-like behavior in the MAM-E17 neurodevelopmental model of schizophrenia. Rats were socially isolated for 10 days during adolescence (postnatal days (P) 30-40), followed by resocialization until late adolescence (P45-P48) or early adulthood (P70-P75); behavioral and neurochemical studies were performed at these ages. The behavioral studies analyzed locomotor activity, social interaction, recognition memory, and sensorimotor gating; GAD65 and GAD67 protein levels were measured in the prefrontal cortex...
