Caracterización conductual y neuroinmune de la resiliencia al estrés social: Efectos reforzantes de la cocaína
2020
Numerosos estudios preclínicos han demostrado que el estrés social incrementa la vulnerabilidad a los efectos reforzantes de la cocaína. Sin embargo, los resultados obtenidos no son homogéneos, observándose siempre una subpoblación que no muestra dicho incremento. Utilizando el modelo de derrota social (DS) repetida en ratones, en este trabajo hemos querido caracterizar conductualmente a los ratones resilientes al incremento de los efectos reforzantes de la cocaína inducido por el estrés social. Utilizamos ratones adultos macho de la cepa C57/BL6 a los que sometimos al protocolo de DS repetida y tres semanas más tarde, realizamos el Condicionamiento de Preferencia de Lugar (CPL) inducido po…
Methods for Evaluating the Interaction Between Social Stress and Environmental Enrichment in Animal Models of Nicotine Addiction
2019
The environmental enrichment (EE) paradigm has been evaluated as a means of counteracting some of the consequences of chronic stress in rodents as well as a model of protective environment against drug abuse development. In the present chapter, our main aim is to describe the models of EE and chronic social stress and how they can be applied jointly in order to evaluate the effects of early psychosocial stress in animals exposed of different environments (enriched environment or standard environment). Furthermore, both paradigms could be applied in animal models of nicotine addiction, so the guidelines for the application of a chronic oral nicotine treatment in mice will be described. The h…
P-70REPEATED SOCIAL STRESS REVERSED ETHANOL-INDUCED CONDITIONED PLACE AVERSION IN MALE MICE
2015
Exposure to stressors can produce behavioural and neurochemical adaptations that render individuals more prone to drug-seeking and drug-taking behaviours. It is well know that stress experiences are a risk factor for alcohol abuse in humans and recent studies in animal models reported that repeated social stress increased alcohol consumption. The aim of the present work is to evaluate the long-term …
UBFC-Phys: A Multimodal Database For Psychophysiological Studies of Social Stress
2021
As humans, we experience social stress in countless everyday-life situations. Giving a speech in front of an audience, passing a job interview, and similar experiences all lead us to go through stress states that impact both our psychological and physiological states. Therefore, studying the link between stress and physiological responses had become a critical societal issue, and recently, research in this field has grown in popularity. However, publicly available datasets have limitations. In this article, we propose a new dataset, UBFC-Phys, collected with and without contact from participants living social stress situations. A wristband was used to measure contact blood volume pulse (BVP…
N6 -Methyladenosine Modification in Chronic Stress Response Due to Social Hierarchy Positioning of Mice
2021
Appropriately responding to stressful events is essential for maintaining health and well-being of any organism. Concerning social stress, the response is not always as straightforward as reacting to physical stressors, e.g., extreme heat, and thus has to be balanced subtly. Particularly, regulatory mechanisms contributing to gaining resilience in the face of mild social stress are not fully deciphered yet. We employed an intrinsic social hierarchy stress paradigm in mice of both sexes to identify critical factors for potential coping strategies. While global transcriptomic changes could not be observed in male mice, several genes previously reported to be involved in synaptic plasticity, l…
Customer-related social stressors and service providers' affective reactions
2012
Summary Previous research has shown that customer-related social stressors (CSS) have negative effects on service providers' long-term well-being. Little is known, however, about short-term and mid-term affective stress reactions and reciprocal effects between service providers' affect and CSS. The aim of this study was to expand extant research (i) by analyzing service providers' short-term (across a day) and mid-term (across 2 weeks) affective reactions to perceived CSS; (ii) by analyzing intraindividual as well as interindividual effects; and (iii) by investigating reciprocal effects of affective reactions and CSS that may eventually lead to psychosocial cycles. Our study employed a diar…
Customer-Related Social Stressors
2015
Abstract. The purpose of this study was to replicate the dimensions of the customer-related social stressors (CSS) concept across service jobs, to investigate their consequences for service providers’ well-being, and to examine emotional dissonance as mediator. Data of 20 studies comprising of different service jobs (N = 4,199) were integrated into a single data set and meta-analyzed. Confirmatory factor analyses and explorative principal component analysis confirmed four CSS scales: disproportionate expectations, verbal aggression, ambiguous expectations, disliked customers. These CSS scales were associated with burnout and job satisfaction. Most of the effects were partially mediated by …
Masculinity ideology and psychological strain: Considering men’s social stressors in female-dominated occupations
2015
According to the gender role strain paradigm (GRSP), men's adherence to masculinity ideology could result in dysfunction strain when it becomes incompatible with other role demands. To support the relevance of GRSP in the work context, we explored the relationship between masculinity ideology and st
Social defeat and subordination as models of social stress in laboratory rodents: A review
1998
This paper is a review of the main research topics currently investigated in laboratory rodents using the stress of defeat or subordination as ethologically relevant models of social stress. First, the main characteristics of the resident/intruder paradigm and the colony models are given. Second, a general description of the behavioral, neuroendocrinological, physiological, neurochemical, neurological, and immunological responses found with these models, and their temporal dynamics, are discussed. Finally, the studies carried out that compare the response induced by social stress with that observed with more conventional models are also reviewed. It is concluded that these animal models of …
Influences of Relatedness, Food Deprivation, and Sex on Adult Behaviors in the Group-living Insect Forficula auricularia
2014
The evolution of group living is generally associated with the emergence of social behaviors that ensure fitness benefits to group members. However, the expression of these behaviors may depend on group composition, which can vary over time with respect to sex, starvation status, and relatedness. Here, we investigated (1) whether adults of the group-living European earwig, Forficula auricularia, show cooperative behaviors toward conspecifics and (2) whether sex, food availability, and relatedness shape the nature and frequency of these behaviors. We conducted a full-factorial experiment using 108 unisexual pairs of adults, in which we manipulated these three factors and video-recorded the e…
