RESUMO

This study aimed to investigate the influence of attention and intelligence in the prediction of prosocial behavior by direct aggression (proactive or reactive) in school-aged children at risk for behavioral problems. The sample was composed of 64 children aged 6 to 8 years screened for risk of behavioral problems, who were enrolled in a clinical trial. Multiple regression models were tested to investigate the prediction of prosocial behavior by direct aggression (proactive or reactive), attention, and intelligence. Additive multiple moderation models were tested to analyze the conditional effect of attention and intelligence in the prediction of prosocial behavior by proactive and reactive aggression. Aggression (proactive or reactive), attention, and intelligence did not linearly predict prosocial behavior. Conditional effects were found only for the proactive aggression model. Negative impacts on prosocial behavior were observed among children with low attention and high intelligence performance, while medium and high levels of attention showed to be protective factors among low to medium intellectual ability children. Clinical impacts of the results are discussed.

RESUMO

While the influence of high-status peers on maladaptive behaviors is well-documented, socialization processes of prosocial behavior through high-status peers remain understudied. This study examined whether adolescents' prosocial behavior was influenced by the prosocial behavior of the peers they liked and whether this effect was stronger when the peers they liked were also well-liked by their classmates. Three waves of data, six months apart, were collected among Chilean early adolescents who completed peer nominations and ratings at Time 1 (n = 294, Mage = 13.29, SD = 0.62; 55.1% male), Time 2 (n = 282), and Time 3 (n = 275). Longitudinal social network analyses showed that adolescents adopted the prosocial behavior of the classmates they liked - especially if these classmates were well-liked by peers in general. In addition, adolescents low in likeability were more susceptible to this influence than adolescents high in likeability. The influence resulted both in increases and - especially - decreases in prosocial behavior, depending on the level of prosociality of the liked peer. Findings suggest that likeability represents an important aspect of peer status that may be crucial for understanding the significance of peer influence with respect to prosocial behaviors during adolescence.

RESUMO

This study addresses the challenge of low blood donation rates in developing countries by examining the effectiveness of a barrier-removal incentive-a one-day transportation voucher-to promote blood donation. Utilizing a longitudinal dataset of 23,750 donors from a Brazilian blood collection agency (BCA) collected between March 2018 and May 2020, we examine the short and long-term effects of this campaign on donation rates. Our results show that the incentive had a large positive influence on both donation attempts and successful donations on the day of the campaign. However, the short-term success of the intervention had an unintended consequence: the significant increase in prospective donors' waiting time at the BCA during the intervention day, which may help explain the negative impact on return rates in the 24-month follow-up. Despite these opposing outcomes, the net effect of the one-day blood donation incentive was still positive, offering valuable insights for BCAs aiming to enhance donor recruitment and retention strategies and emphasizing the need to balance immediate benefits with potential long-term impacts.

RESUMO

Resumen (analítico) En Colombia no existen estudios consolidados que muestren la existencia de conductas prosociales y menos indicadores que reflejen cómo estas conductas pueden influir en la reducción de los comportamientos agresivos. Lo que sí se sabe por estudios previos es que las conductas de naturaleza altruista parecen incompatibles con la agresividad. El artículo recoge los resultados de una investigación que describe las conductas prosociales de los niños de este contexto. El estudio de tipo transversal se realizó con 587 niños entre los 9 y 12 años. Los resultados evidencian niveles elevados de prosocialidad y diferencias significativas a favor de las niñas en casi todas las dimensiones evaluadas. Con la presencia de estos comportamientos se puede inferir que la prosocialidad representa un activo muy importante para prevenir manifestaciones agresivas en las escuelas.

Abstract (analytical) In Colombia there are no consolidated studies that evidence the existence of prosocial behavior. There are very few indicators that measure how these behaviors can help reduce levels of aggression and violence. What is known from previous studies is that altruistic behaviors seem incompatible with aggression. This article summarizes the results of an investigation that describes the prosocial behaviors of children in the Colombian context. A cross-sectional study was carried out with 587 children between 9 and 12 years of age. The results show high levels of prosocial behavior among girls and significant differences among members of this gender group in almost all of the dimensions that were evaluated. Based on these results, it can be inferred that prosocial behavior represents a very important asset that helps prevent acts of aggression in schools.

RESUMO

INTRODUCTION: Peer violence is a serious type of school violence that is associated with emotional and behavioral problems. OBJECTIVE: To analyze violence between peers associated with students' social skills. METHODS: We used a cross sectional survey nested in a cluster randomized controlled trial to evaluate peer violence among elementary school students and its association with prosocial behaviors and mental problems. Teachers answered an adapted version of the Revised Olweus Bully/Victim Questionnaire and the Brazilian adaptation of the Teacher Observation of Classroom Adaptation-Checklist (TOCA-C) scale for each student. Children completed a sociodemographic questionnaire. The participants were 1,152 5-14-year-old children from Brazilian public schools; 79.70% reported being involved in violent situations. RESULTS: Children who had both committed and suffered violence were less likely to exhibit prosocial behaviors. Children who committed and suffered violence and those who only committed were more likely to experience concentration problems and disruptive behaviors. DISCUSSION: This study suggests that peer violence is associated with lower prosocial behaviors and more behavioral problems. Thus, more specialized mental health care is required for children involved in peer violence, in addition to the possibility of implementing and maintaining programs to prevent and reduce violence and to develop prosocial behaviors in schools.

RESUMO

Diversos estudios han mostrado que existe una asociación entre el comportamiento prosocial y la habilidad empática. La forma más frecuente de evaluar ambos constructos es a través de escalas de autorreporte, siendo la Escala de Conducta Prosocial (ECP) y el Indice de Reactividad Interpersonal (IRI) las más utilizadas en población adulta. Hasta el momento, no hay reportes disponibles sobre la relación entre la empatía y la conducta prosocial en adultos de habla hispana evaluados con dichas escalas. Objetivo: Evaluar la conducta prosocial utilizando la ECP en personas adultas de habla hispana y analizar su interacción con la empatía evaluada con la escala IRI, así como también identificar su relación con otras variables de interés (edad, género y orden de presentación de las escalas durante la evaluación). Método: Se administró la ECP y el IRI a una muestra de 115 participantes, quienes fueron asignados de manera aleatoria a un orden específico de exposición a las escalas (IRI-ECP y ECP-IRI). Resultados: El rendimiento en la ECP mostró estar asociado a la edad y a la interacción entre el rendimiento en el IRI y el género, mientras que el orden de presentación de las escalas no mostró asociación con las puntuaciones. Conclusión: La empatía y variables sociodemográficas como el género y la edad se relacionan con las conductas prosociales de individuos adultos de habla hispana y por lo tanto deben considerarse en la evaluación.

Previous research has shown an association between prosocial behavior and empathic ability. These constructs are normally assessed in the adult population using self-report scales, such as Prosocial Behavior Scale (ECP) and Interpersonal Reactivity Index (IRI). Currently, there is no available data about the interaction between empathy and prosocial behavior assessed with these scales in Spanish-speaking adults. Objective: To assess prosocial behaviors using ECP in Spanish-speaking adults and analyze its interaction with empathy assessed with IRI, as well as identify the relationship with other variables of interest (age, gender and order of presentation of the scales during the assessment). Method: ECP and IRI were administered to a sample of 115 subjects, who were randomly assigned to a specific order of exposure to the scales (IRI-ECP and ECP-IRI). Results: Performance on ECP was associated with age and the interaction between IRI scores and gender. The order in which the scales were presented during assessment showed no association with ECP scores. Conclusion: Empathy and sociodemographic variables, such as gender and age, are associated with prosocial behaviors of Spanish-speaking adults and therefore need to be considered during the assessment.

Objetivo: Avaliar o comportamento pró-social por meio da ECP em adultos falantes de español e analizar sua interação com a empatia availada com a escala IRI, bem como identificar sua relação com outras variáveis de interesse (idade, gênero e ordem de apresentação das escalas durante a avaliação). Método: A ECP e o IRI foram aplicados a uma amostra de 115 participantes, os quais foram aleatoriamente designados para uma ordem específica de exposição às escalas (IRI-ECP e ECP-IRI). Resultados: O desempenho na ECP mostrou-se associado à idade e à interação entre o desempenho no IRI e o gênero, enquanto a ordem de apresentação das escalas não apresentou associação com os escores. Conclusão: A empatia e variáveis ​​sociodemográficas como gênero e idade estão relacionadas aos comportamentos pró-sociais de indivíduos adultos falantes de espanhol e, portanto, devem ser consideradas na avaliação.

RESUMO

This two-year longitudinal study examined Mexican-origin adolescents' need to belong and cognitive reappraisal as predictors of multiple forms of prosocial behavior (i.e., general, emotional, and public prosocial behaviors). Prosocial behaviors, which are actions intended to benefit others, are hallmarks of social proficiency in adolescence and are influenced by intrapersonal abilities and motivations that typically develop during adolescence. Yet, few studies of Mexican-origin or other U.S. Latinx youths have examined whether such individual difference characteristics, specifically social motivation and emotion regulation skills, support prosocial behavior. In a sample of 229 Mexican-origin youth (Mage = 17.18 years, SD = 0.42, 110 girls), need to belong, cognitive reappraisal, and general prosocial behaviors were assessed at ages 17 and 19. Emotional and public forms of prosociality also were assessed at age 19. Cognitive reappraisal was positively associated with concurrent general prosociality at age 17, whereas need to belong was positively associated with concurrent public prosociality at age 19. Moderation analyses revealed that general and emotional types of prosocial behaviors at age 19 were lowest for youth with both lower need to belong and less use of cognitive reappraisal at 19 years. Greater cognitive reappraisal skills and need to belong may reflect distinct motivations for engaging in varying forms of prosocial behavior in late adolescence.

RESUMO

Los bebés exhiben una amplia gama de comportamientos prosociales, que incluyen ayudar, compartir, consolar y cooperar. En la infancia, estos comportamientos se vuelven más sofisticados y socialmente apropiados. El objetivo de esta investigación es identificar y revisar sistemáticamente la literatura que ha incorporado el estudio de la figura paterna y su impacto en el desarrollo de la conducta prosocial en los niños/as entre los 0 y 5 años. Método, utilizando la metodología PRISMA, se realiza una búsqueda y análisis de artículos científicos en las bases de datos Scopus y Web of Science, considerando criterios de inclusión y exclusión establecidos. Resultados, se seleccionaron 28 artículos y el análisis de sus resultados indica que el padre tiene un impacto en el desarrollo de la conducta prosocial de los niños entre los 0 y 5 años. El ejercicio del rol paterno y el apoyo entregado por el padre, favorece que el niño/a manifieste conductas prosociales desde la infancia temprana, en la relación con sus figuras significativas y con terceros, de forma directa e indirecta, en los distintos contextos de socialización.

Infants exhibit a wide range of prosocial behaviors, including helping, sharing, comforting, and cooperating. In infancy, these behaviors become more sophisticated and socially appropriate. The aim of this research is to systematically identify and review the literature that has incorporated the study of the father figure and its impact on the development of prosocial behavior in children aged 0-5 years. Method, using the PRISMA methodology, a search and analysis of scientific articles in the Scopus and Web of Science databases was carried out, considering established inclusion and exclusion criteria. Results, 28 articles were selected and the analysis of their results indicates that fathers have an impact on the development of prosocial behavior in children between 0 and 5 years of age. The exercise of the paternal role and the support provided by the father, favors the child to manifest prosocial behaviors from early childhood, in the relationship with their significant figures and with third parties, directly and indirectly, in the different socialization contexts.

RESUMO

The first goal of the current research was to study the short-term developmental patterns of ingroup and outgroup prosocial behavior during the middle adolescence stage among Uruguayan and Colombian adolescents. The second goal was to study the probability of inclusion in each trajectory class arising from gratitude and forgiveness (understood as the absence of negative emotions and the presence of positive emotions toward an aggressor) while controlling for gender and age. The study included two short-term longitudinal samples from two Latin American countries: Colombia (N = 212, M age = 13.82 years, SD = 1.25) and Uruguay (N = 269, M age = 14.02 years, SD = 1.39). The data were collected at three time points within a 3-month interval. The first finding indicated that different patterns in ingroup and outgroup prosocial behavior in adolescents emerged in both Latin American countries. Moreover, two classes-high and low-were identified in the trajectory of ingroup prosocial behavior, while three different classes-high, moderate, and low-were found in the trajectory of outgroup prosocial behavior in both countries. The results indicated that high levels of gratitude increased the probability that Uruguayan adolescents were included in the group of adolescents with high levels of ingroup prosocial behavior. High levels of positive emotions toward an aggressor (a dimension of forgiveness) increased the probability that a Colombian adolescent belonged to the group of adolescents with high levels of ingroup prosociality. Regarding outgroup prosocial behavior, different predictors were also identified between the countries. The results indicated that high levels of gratitude and positive emotions toward an aggressor increased the probability that Uruguayan adolescents were included in the group of adolescents with high or moderate levels of outgroup prosocial behavior. Only positive emotions toward an aggressor increased the probability that Colombian adolescents were included in the group of adolescents with high or moderate levels of outgroup prosocial behavior.

RESUMO

El presente estudio tuvo como objetivo el diseño y vali- dación de una escala para evaluar comportamiento con- traproducente en línea que incluye el análisis conjunto de conductas destructivas (antisociales) y constructivas (prosociales). Además, se propuso determinar qué ras- gos de personalidad (normales, patológicos, negativos o positivos) predicen dicho comportamiento. Participaron 351 sujetos de población general argentina (156 hombres, 191 mujeres, 2 se identificaron como no binarios), con una edad promedio de 39.35 años (de = 13.79). Para el cumplimiento de todos los objetivos, aparte de la prueba construida, se emplearon los siguientes instrumentos: Big Five Inventory, Personality Inven- tory for DSM-5 Brief-Form, Positive Traits Inventory Short-Form, Dark Triad Scale, y una encuesta diseñada ad hoc para evaluar el uso de internet y redes sociales. El análisis factorial exploratorio reveló una estructura de dos factores orientados a la evaluación de los dos tipos de conductas, que explicaban el 57.5 % de la varianza total. Como resultado, se dio lugar a una escala de 18 ítems con muy buenos valores de fiabilidad ­coeficiente omega­ (conductas destructivas ω = 0.88; conductas constructivas ω = 0.79). Por último, se realizaron análisis de regresión jerárquica que determinaron que los rasgos de la tríada oscura son los que mejor predicen el desarrollo de conductas destructivas, en tanto que los rasgos positivos predicen las conductas constructivas. Palabras clave: rasgos de personalidad; comportamiento en línea; antisocial; prosocial.

The present study aimed to design and validate a scale to assess online counterproductive behavior that includes the joint analysis of destructive (antisocial) and constructive (prosocial) behaviors. In addition, it was studied which personality traits (normal, pathological, negative or positive) predict this counterproductive behavior. 351 subjects from the general Argentine population participated (156 men, 191 women, 2 identified themselves as non-binary), with an average age of 39.35 years (SD = 13.79). In order to achieve the objectives, in addition to the constructed test, the follow- ing instruments were used: Personality Inventory for dSM-5 Brief-Form, Positive Traits Inventory Short-Form, Dark Triad Scale, and a survey designed ad hoc to assess internet and social media sites use. The exploratory factor analysis revealed a two-factor structure ­oriented to the evaluation of the two types of behaviors­ that explained 57.5 % of the total variance. As a result, a scale of 18 items with very good reliability values ­omega coefficient­ (destructive behaviors ω = 0.88; constructive behaviors ω = 0.79) was developed. Finally, hierarchical regression analyzes were performed. The results showed that the Dark Triad traits best predict destructive behaviors, while positive traits predict constructive behaviors.

RESUMO

To promote prosocial behaviour, in the present study, we observed the human values that may predict it within the realms of the transcendental views of life, society's shared culture and the world of personal and interpersonal affections. To do this, we started with two hypotheses: (1) prosocial behaviour differs according to gender and participation in volunteering; and (2) the variables of transcendental values, cultural development, affective development, gender and participation in volunteering predict prosocial behaviour.To do so, we conducted a quantitative study based on the cross-sectional, social analytical-empirical research method. We used a validated instrument with a large sample of 1,712 individuals living in the multicultural context of the Spanish city of Melilla, located in North Africa and one of only two land borders between Europe and Morocco. Values that could promote prosocial behaviour were grouped into four dimensions to locate relevant factors that helped identify which values are linked to specific actions, both formal and informal, through an inferential analysis focusing on regression and multivariate analysis of variance.Our findings highlighted the linkage of the transcendent dimension of the individual in relation to his or her level of prosocial behaviour and the role of women as socialising agents.

RESUMO

Prosocial values play a critical role in promoting care and concern for the well-being of others and prioritizing the common good of society. Evidence from population-based reports, cognitive neuroscience, and clinical studies suggests that these values depend on social cognition processes, such as empathy, deontological moral cognition, moral emotions, and social cooperation. Additionally, indirect evidence suggests that various forms of prosocial behaviors are associated with positive health outcomes at the behavioral, cardiovascular, immune, stress-related, and inflammatory pathways. However, it is unclear whether prosociality can positively influence brain health outcomes. In this perspective, we propose that prosocial values are not only influenced by brain conditions but could also potentially play a role in protecting brain health. We review studies from various fields that support this claim, including recent reports of prosociality-based interventions impacting brain health. We then explore potential multilevel mechanisms, based on the reduction of allostatic overload at behavioral, cardiovascular, immune, stress-related, and inflammatory levels. Finally, we propose potential prosociality-based interventions for improving brain health in at-risk populations, such as psychiatric and neurological patients, and individuals exposed to poverty or violence. Our perspective suggests that prosocial values may play a role in promoting and maintaining healthy brains.

RESUMO

Resumen La empatía positiva implica una expresión de felicidad o alegría, la cual es resultado de comprender la condición emocional positiva de otra persona y compartirla. El objetivo de esta investigación fue evaluar las propiedades psicométricas de la adaptación de la Escala Disposicional de Empatía Positiva (Dispositional Positive Empathy Scale) en población adolescente argentina. El instrumento sobre el cual se realizó la adaptación está compuesto por siete ítems, originalmente en idioma inglés. La muestra (n = 303) estuvo conformada por 95 varones (31 %) y 208 mujeres (69 %), con edades entre 11 y 17 años, estudiantes de secundaria. Se estudió la validez de constructo realizando un análisis factorial confirmatorio y la invariancia de la escala en relación con el sexo y edad de los participantes. Se comprobó la validez convergente con la conducta prosocial hacia diversos objetivos, las diferencias de los niveles de empatia positiva entre los sexos y en distintos grupos de edad y los niveles de fiabilidad (Ω = .78). Los resultados indican que la escala es unidimensional, coincidiendo con la versión original. Se encontró un buen ajuste del modelo a los datos (CFI = .98; TU = .96; NNFI = .96; NFI = .95; RMSEA = .05). El modelo permaneció constante en ambos sexos y grupos de edades. La empatia positiva se relacionó con la prosocialidad y se encontraron diferencias según sexo y edades. Los hallazgos dan cuenta de que las características psicométricas de la adaptación de la Escala Disposicional de Empatía Positiva a población adolescente argentina son satisfactorias.

Abstract Positive empathy implies an expression of happiness or joy, resulting from understanding the positive emotional condition of another person and sharing it. The aim of this research was to evaluate the psychometric properties of the adaptation of the Dispositional Positive Empathy Scale in the Argentine adolescent population. The instrument on which the adaptation was made consists of seven items, originally in English. The sample (N = 303) was made up of 95 males (31 %) and 208 females (69%), aged between 11 and 17 years old, high school students. Construct validity was studied by performing a confirmatory factor analysis and the invariance of the scale in relation to the sex and age of the participants. Convergent validity was verified with prosocial behavior towards various goals, differences in levels of positive empathy between sexes and across different age groups, and reliability levels (Ω = .78) were tested. The results indicate that the scale is one-dimensional, coinciding with the original version. A good fit of the model to the data was found (CFI = .98; TLI = .96; NNFI = .96; NFI = .95; RMSEA = .05). The model remained constant across both sexes and age groups. Positive empathy was related to prosociality and differences were found according to sex and age. The findings show that the psychometric characteristics of the adaptation of the Positive Empathy Dispositional Scale to the Argentine adolescent population are satisfactory.

RESUMO

The purpose of this research is to analyze the empirical evidence on the relationship between social cognition and prosocial behavior in children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD). A systematic review was carried out following the PRISMA guidelines of empirical studies found in PubMed and Scopus databases, including a total of 51 research studies. The results indicate that children and adolescents with ADHD have deficits in social cognition and prosocial behavior. For children with ADHD, their deficits in social cognition highlight their difficulty in the process of theory of mind, emotional self-regulation, emotion recognition and empathy, affecting prosocial behavior, evidencing difficulty in personal relationships, and the creation of emotional bonds with their peers.

RESUMO

Díaz-Loving et al. (1986) diseñaron la Escala Multi- dimensional de Empatía (EASE), un instrumento culturalmente válido para población mexicana inspirado en la estructura conceptual del Índice de Reactividad Interpersonal (IRI) (Davis, 1980). En esta investigación presentamos evidencias de validez y confiabilidad de la Escala Corta de Empatía (ECE), una versión breve de la EASE aplicada a 674 participantes (50.8 % mujeres, 49.2 % hombres) mexicanos (M = 22.8 años, de = 9.2), además del IRI, preguntas de conductas prosociales y el Inventario de Personalidad de diez ítems como criterios externos de validez. El análisis factorial exploratorio mostró tres factores ­malestar personal, toma de perspectiva y compasión­ con niveles de confiabilidad adecuados. El análisis factorial confirmatorio verificó la estructura con indicadores de bondad de ajuste aceptables, obteniendo evidencias de equivalencia estructural para mujeres y hombres. Las relaciones de los tres factores de ECE con prosocialidad, personalidad y sexo proporcionan criterios de validez externa del instrumento.

The Multidimensional Empathy Scale (EASE), a culturally valid instrument for the Mexican population inspired by the conceptual structure of the Interpersonal Reactivity Index (IRI), from 1980, was designed in 1986. The article presents evidence of the validity and reliability of the short empathy scale (ECE), a short version of the EASE, applied to 674 Mexican partici- pants (50.8 % women, 49.2 % men; M = 22.8 years, sd = 9.2). They also answered questions on prosocial behaviors and the 10-item Personality Inventory as an external validity criterion. The exploratory factor analysis showed three factors (personal discomfort, perspective-taking, and compassion) with adequate levels of reliability. The confirmatory factor analysis verified the structure with acceptable goodness-of-fit indicators, obtaining evidence of structural equivalence for women and men. The relationships of the three ECE factors with prosociality, personality, and sex provide evidence of validity.

RESUMO

Introduction: Prosocial behavior refers to sharing emotions and sensations such as pain. Accumulated data indicate that cannabidiol (CBD), a nonpsychotomimetic component of the Cannabis sativa plant, attenuates hyperalgesia, anxiety, and anhedonic-like behavior. Nevertheless, the role of CBD in the social transfer of pain has never been evaluated. In this study, we investigated the effects of acute systemic administration of CBD in mice that cohabited with a conspecific animal suffering from chronic constriction injury. Furthermore, we assessed whether repeated CBD treatment decreases hypernociception, anxiety-like behavior, and anhedonic-like responses in mice undergoing chronic constriction injury and whether this attenuation would be socially transferred to the partner. Materials and Methods: Male Swiss mice were Housed in pairs for 28 days. On the 14th day of living together, animals were then divided into two groups: cagemate nerve constriction (CNC), in which one animal of each partner was subjected to sciatic nerve constriction; and cagemate sham (CS), subjected to the same surgical procedure but without suffering nerve constriction. In Experiments 1, 2, and 3 on day 28 of living together, the cagemates (CNC and CS) animals received a single systemic injection (intraperitoneally) of vehicle or CBD (0.3, 1, 10, or 30 mg/kg). After 30 min, the cagemates were subjected to the elevated plusmaze followed by exposure to the writhing and sucrose splash tests. For chronic treatment (Exp. 4), sham and chronic constriction injury animals received a repeated systemic injection (subcutaneous) of vehicle or CBD (10 mg/kg) for 14 days after the sciatic nerve constriction procedure. On days 28 and 29 sham and chronic constriction injury animals and their cagemates were behaviorally tested. Results and Conclusion: Acute CBD administration attenuated anxiety-like behavior, pain hypersensitivity, and anhedonic-like behavior in cagemates that cohabited with a pair in chronic pain. In addition, repeated CBD treatment reversed the anxiety-like behavior induced by chronic pain and enhanced the mechanical withdrawal thresholds in Von Frey filaments and the grooming time in the sucrose splash test. Moreover, repeated CBD treatment effects were socially transferred to the chronic constriction injury cagemates.

RESUMO

Autonomous sensory meridian response (ASMR) describes the experience of a pleasant body sensation accompanied by a feeling of well-being and relaxation in response to specific audiovisual stimuli, such as whispers and personal attention. Previous work suggests a relationship between this experience with the processing of affective and body states; however, no research has explored differences in interoception between people experiencing ASMR and those who do not. We hypothesized that the ASMR experience is based on interoception processing. To test this, we assessed group differences across different dimensions of interoception: Interoceptive sensibility (IS), measured using the multidimensional assessment of interoceptive awareness (MAIA); Interoceptive accuracy score (IAS), measured by calculating performance in a heartbeat counting task (HCT), and the electrophysiological index of interoception, the heartbeat evoked potential (HEP), which was calculated during the HCT and an ASMR tingle reporting task (ASMR-TRT). Our results showed that IS and IAS, dimensions requiring conscious awareness, showed no differences between groups. However, HEP amplitude was larger in the ASMR group in both tasks. We concluded that the ASMR experience is based on an unconscious interoceptive mechanism, reflected by HEP, where exteroceptive social-affective stimuli are integrated to represent a body state of positive affective feelings and relaxation, as has been described for affective touch. The relevance of this finding relies on that interoceptive function, body regulation, and emotional/affective experiences are fundamental for well-being, and the relationship between ASMR and interoception opens the way to future research exploring the causal relationship between them and their potential clinical applications.

RESUMO

Positive psychology is vital in increasing prosocial behavior and reducing bullying. However, limited studies have analyzed the influence of positive personal characteristics on the prosocial behaviors of bystanders in bullying. The present study examined direct and indirect relationships between spirituality, happiness, altruism, and prosocial bystander behavior in bullying. Participants in this study were 685 students from Northwestern Mexico; 51% were male and 49% female, between 12 and 18 years old (M = 14.3 years, SD = 1.68). A structural equation model (SEM) was calculated. The results indicate that happiness and altruism were related to prosocial bystander behavior. Spirituality and happiness have an indirect relationship by increasing prosocial bystander behavior through the positive effects of altruism. The SEM explained 48% of the variance of the prosocial bystander. The implications for improving defensive behavior in bullying and reducing school violence are discussed.
