abstract: Friendships make us happy, keep us healthy, and can even facilitate our reproductive fitness. But most friendships are not forever—even when we want them to be. How do people maintain valued friendships? I propose that “friendship jealousy” arises when people perceive others as posing threats to valued friendships, and that this response can function to prevent friendship loss and friend defection. In preliminary experiments, I tested predictions derived from this functional view. As predicted, I found, first, that friendship jealousy is calibrated to friend value. Second, friendship jealousy predicts intentions to “friend guard” (i.e., engage in behavior to protect the friendship). Third, friendship jealousy has sex-differentiated features, which are consistent with sex differences in friendship structures and ancestral friendship functions. The present work pits against one another intuitive and functional predictions as to what drives friendship jealousy. Although intuition might lead one to expect greater jealousy when a friend spends more time with a new person, a functional view suggests greater jealousy when that new person threatens to fulfill the same function for one’s friend that one is currently fulfilling (i.e., to “replace” him/her). Preliminary studies revealed that greater friendship jealousy is evoked when friends form new same-sex friendships (which presumably pose greater replacement threat, but lesser time threat) versus new romantic relationships (which presumably pose lesser replacement threat, but greater time threat). The focal experiment explicitly and experimentally manipulates a version of “replacement threat” (whether the best friend “chooses” the new friend over you) and “time threat” (how much time the best friend spends with the new friend). In line with functional predictions, the amount of time the best friend spends with a new friend drives friendship jealousy—but only when direct information about replacement threat is unavailable. Regardless of the time threat posed, participants report high friendship jealousy when replacement threat is high, and low friendship jealousy when replacement threat is low. Results imply that friendship jealousy is calibrated to replacement threat (over time threat). Overall, findings suggest that friendship jealousy might be a functional response aimed at facilitating friendship maintenance. / Dissertation/Thesis / Doctoral Dissertation Psychology 2018

Infants have an innate desire to form social bonds and jealousy protests are observed when an infant is trying to regain attention lost by a caregiver to a social competitor. The current study examined jealousy responses during the first year of life, between 6- to 9-months of age and 12- to 18-months of age, in response to loss of exclusive maternal attention, in addition to exploring implications for mother-infant attachment, EEG asymmetry, and cortisol reactivity and regulation. At both age groups, infants demonstrated increased approach behaviors when infants are faced with a social rival, in addition, left-frontal EEG asymmetry was associated with maternal-directed approach behaviors during the social rival condition. In the 6- to 9-month sample, left-frontal EEG asymmetry also demonstrated an association with infants regulatory abilities, measured by salivary cortisol. This study provides further evidence for the emerging links between social and emotional responses in infancy due to loss of exclusive maternal attention. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

It is the act of extreme violence between couples, which occurs when the individual is taken by a sense of passion and intense emotion, going berserk in a situation of threat or loss of the object of love. The field of interest of this research is understanding the motivations for carrying out the crime of passion, the perceptions upon the act on individuals deprived of liberty, the insight into the emotional aspects linked to the crime committed, and the comprehension of offenders perception about the prison experience. Survey participants were offenders who committed the crime of passion against intimate partners, and were imprisoned in a detention facility in Viana, Angola. This study has a qualitative nature, utilizing a semi-structured interview as a research tool. The sample selected for the survey included 17 male participants, among which four were awaiting trial and thirteen had already been convicted. The age of respondents ranged between 26 and 54 years old. Categories were defined after the analysis of the contents of interviews. The theoretical approach was the psychodynamic psychology, which helped us understand the behavior of the subjects. The results revealed that the main reasons pushing the individuals to the crime of passion were jealousy and betrayal arisen by the presence of a rival, real or imaginary, stimulating the subject to evoke a mixture of thoughts, feelings, emotions and behaviors that aroused in him lack of control, intolerance and frustration, mobilizing him to the act of extreme violence / O crime passional é um fenômeno sociocultural que afeta a saúde pública. É o ato de violência extrema entre casais, que ocorre quando o sujeito é tomado por um sentimento de paixão e emoção intensa, descontrolando-se diante de uma situação de ameaça ou perda do objeto de amor. A presente pesquisa tem como campo de interesse a compreensão das motivações para a realização do crime passional, as percepções sobre o ato em sujeitos privados de liberdade, a apreensão dos aspectos emocionais ligados ao crime cometido e a percepção dos infratores a respeito da vivência carcerária. Os participantes da pesquisa eram infratores que cometeram crime passional contra as parceiras íntimas, e se encontravam encarcerados no estabelecimento prisional de Viana, em Angola. O método de estudo utilizado é de caráter qualitativo, e o instrumento de investigação foi a entrevista semiestruturada. A amostra selecionada para a pesquisa reuniu 17 participantes do sexo masculino, dos quais quatro se encontravam à espera de julgamento e treze já tinham sido condenados. A faixa etária dos entrevistados situava-se entre 26 e 54 anos de idade. As categorias foram definidas após a realização da análise do conteúdo das entrevistas. A abordagem teórica foi a psicologia psicodinâmica, que nos ajudou a compreender o comportamento dos sujeitos. Os resultados apontaram que os principais motivos que impulsionaram os sujeitos ao crime passional foram o ciúme e a traição, que surgiram com a presença de um rival, real ou imaginário, suscitando no indivíduo a evocação de uma mistura de pensamentos, sentimentos, emoções e comportamentos que nele despertaram descontrole, intolerância e frustração, mobilizando-o para o ato de violência extrema

以往有關Lee(1973)所提之六種愛情類型的研究，都只探討愛情類型分量表得分與一些變項間的相關（例如，自尊、性態度、關係滿意度、性別等），關於不同愛情類型分量表得分與嫉妒的關係及不同愛情類型的配對與關係滿意度之闗係則從未被論及，因此，這些未被討的部份即為本研究的重點。在嫉妒程度與關係滿意度之關係方面，以往研究結果並不一致，研究者認為嫉妒因應行為可能是影響研究結果不一致的原因之一，因此，嫉妒程度、嫉妒因為行為與關係滿意度之間的關係也是本研究所關注的另一個焦點。此外，不同嫉妒程度的配對及不同嫉妒因應行為的配對與關係滿意度之關係這個重要但被忽略的議題也在本研究予以探討。本研究的受試者為126對18歲至35歲，交往半年以上的未婚男女，研究工具為愛情態度量表、人際嫉妒量表、嫉妒因應行為量表及關係評估量表。研究發現情慾之愛、友誼之愛及利他之愛得分越高，關係滿意度越高，且越不常探用間接嫉妒因應行為，而遊戲之愛及依附之愛得分越高，關係滿意度越低，且越常採用間接嫉妒因應行為。情慾之愛、遊戲之愛及依附之愛得分越高，嫉妒程度越高，友誼之愛及利他之愛得分越高，嫉妒程度越低。情慾之愛及利他之愛得分越高，越常採用直接嫉妒因應行為，而遊戲之愛得分越高，越常採用直接嫉妒因應行為，而遊戲之愛得分越高，越不常採用直接嫉妒因應行應。在愛情類型配對方面則發現「相似配對組」的關係滿意度顯著高於「相異配對組」。至於嫉妒程度、嫉妒因應行為與關係滿意之間的關係則發現：男生的嫉妒程度越高，關係滿意度越低，此外研究結果亦顯示常採用直接而少用間接嫉妒因應行為、高嫉妒因應行為及低嫉妒因應行為的受試之關係滿意度皆顯著高於常採用間接而少用直接嫉妒因應行為的受試。在嫉妒程度配對方面的結果顯示「男女皆為低嫉妒組」中的男性關係滿意度顯著高於「男女皆為高嫉妒組」中的男性關係滿意度。上述結果的可能原因均在討論部份予以探討。

This study aims to explore and highlight alternative relationships in relation to the norm of monogamy. The perspective we have had with this study, is of a qualitative and investigative character. We have deeply interviewed four participants who are, or have been, in a polyamorous relationship. We have studied how the respondents see and handle their choices of life. We also wanted to know what kind of reactions they have faced from society. Another issue we have studied deeper is how the participants define jealousy and infidelity. We have anchored the discussion in different relation- and family-related theories to understand and problematize the norm of monogamy. What we come to understand is that the participants found different ways, to satisfy their desires and to fulfill their romantic needs. There have been differences in their desires and needs met in the relationship and we wanted to study how their delimitations seems to vary. Two of our participants have embraced both their romantic and lustful feelings for others and has had a very liberal approach to relationships. The other two participants has only accepted sexual contacts with other people, no feelings involved, and they needed to have an arrangement about this with their partner. Our participants have not experienced any major reactions from the society. However, we have been able to see that they have used various strategies to avoid stigmatization. We could also see that jealousy is often associated with a feeling of ownership.

Male mammals compete for reproductive access to females. Gaining and maintaining this access can be stressful and anxiety-provoking. In humans, anxiety and associated protective behaviors can manifest as jealousy. Physiological stress is likely to increase in relation to jealousy as it does with anxiety. Hypothetically, higher levels of anxiety and cortisol may indicate, and may even promote, strong territorial or jealous behavior. Chronically elevated cortisol has been shown to be deleterious to prefrontal and hippocampal neurons and result in emotional and stress-response dysregulation. In very anxious and jealous individuals, chronic stress activation could further promote these tendencies via emotional disinhibition. Cortisol production also related to vasopressin (AVP) levels and AVP has been shown to increase mate preference and territoriality. Furthermore, physiological measures may be more valid than self-report of less socially desirable behaviors such as jealousy and anxiety. As a preliminary study, we measured salivary cortisol, heart-rate, and blood pressure in relation to self-reported anxiety and jealousy in healthy men and women in response to threatening male faces paired with smiling female faces. Elevated anxiety positively predicted jealousy in men but not women. Anxiety and jealousy also predicted elevated heart rate and blood pressure. Cortisol levels in response to the threat task and in relation to jealousy approached statistical significance (ps < 0.07) and suggest the need for a larger sample size.

Jealousy is a response to a situation in which a person feels a combination of different emotions, such as love, anger, sadness and fear when an affectionate interaction is happening between a loved one and someone else. This paper discusses the definition and onset of infant jealousy, the physiological basis of jealousy, whether maternal factors play a role, as well as studies on jealousy and EEG patterns. It has been argued that infants, as young as six-months-old display jealous-like behaviors. During jealousy evocation conditions, infants demonstrate negative emotions such as protesting or crying, diminished distancing, and heightened gaze toward their mother during maternal inattention. Approach/withdrawal behaviors and electroencephalography (EEG) activation were studied in the context of an infant jealousy paradigm. In this investigation, 45 mother-infants dyads were exposed to a social versus non-social condition during maternal inattention. During the social condition, infants demonstrated increased approach-style gaze and reach and negative affect. EEG was collected during all conditions on a subsample of 15 infants and in agreement with adult jealousy literature (Harmon-Jones, Peterson, & Harris, 2009), infants displayed left midfrontal EEG asymmetry, and displayed more approach motivations during the social doll condition indicative of jealousy approach motivations. / by Alexis K.

Jealous is present since the beginning of the history of humanity, composing the various forms of interpersonal relations, be it in the family, in school, in social life, at work and specially in the affective romantic relations. Evolutionist psychologists propose that this phenomenon happens because of distinct selective pressures suffered by men and women during the natural selection that helped our ancestors and probably keeps helping us until today to face many real reproductive threats. The aim was to test hypothesis connected to the evolutionist theory, besides comparing our results to the literature review. Our sample was composed of 136 male individuals and 136 feminine individuals, who answered a questionnaire referring to personal data, open questions and a scale of measure of jealous as criterion of wishing a partner. Our data allowed us to confirm the hypothesis that confirms that the information concerning the indicative behavior of jealous of the proposed partner influences in the perception of the wishing degree concerning to him/her. However, the hypothesis about the people that had already betrayed and the ones who hadn t concerning to the potential jealous of the partner, and it made the potential partner to be noticed as less desirable, but was not corroborated. The data suggest that biological and cultural factors act influencing themselves mutually concerning the behavior of choice of partners in humans. / O presente estudo pretende desvendar se a percepção do ciúme influencia no processo de escolha de parceiros. O ciúme está presente na história da humanidade desde os seus primórdios, comprometendo as diversas formas de relações interpessoais, quer seja na família, na escola, na vida social, no trabalho e de modo especial nos relacionamentos afetivos de natureza romântica. Psicólogos evolucionistas propõem que este fenômeno se deve a distintas pressões seletivas sofridas por homens e mulheres durante o processo de seleção natural que ajudou nossos ancestrais, e provavelmente continua a nos ajudar hoje, a enfrentar uma hoste de ameaças reprodutivas reais. Constituiu nosso objetivo testar hipóteses ligadas à teoria evolucionista, além de comparar nossos resultados com o que a revisão de literatura. Nossa amostra foi composta de 136 sujeitos do sexo masculino e 136 do sexo feminino, que responderam a um questionário referente a dados pessoais, perguntas abertas e a uma escala de medida de ciúme como critério de desejabilidade de um parceiro. Nossos dados permitiram confirma a hipótese de confirma que a informação a respeito de comportamentos indicativos de ciúme do potencial parceiro influi na percepção do grau de desejabilidade em relação a ele. Entretanto, a hipótese sobre as pessoas que já traíram e as que não traíram quanto ao ciúme do potencial parceiro, e fez com que o potencial parceiro seja percebido como menos desejável, não foi corroborada. Os dados sugerem que fatores biológicos e culturais atuam influenciando-se mutualmente no que tange o comportamento de escolha de parceiros em humanos.

Embora o ciúme romântico e a infidelidade amorosa sejam dois importantes temas que afetam vários relacionamentos humanos e, também, um desafio para muitos destes, seus mecanismos de gênese, ação, associação e conseqüências que podem acarretar para os desdobramentos amorosos ainda não foram totalmente esclarecidos. O presente trabalho teve por objetivo verificar possíveis associações entre estes dois fenômenos. Participaram desta pesquisa 45 casais de namorados heterossexuais com média de idade de 24,6 anos recrutados por meio de um anúncio colocado no site da Universidade de São Paulo (USP). Para avaliar os graus de ciúme dos participantes utilizou-se a Escala de Ciúme Romântico – ECR (versões masculina e feminina) de Ramos. Para avaliar a infidelidade dos participantes foi utilizado o Inventário de Comportamentos Relacionados à Infidelidade, confeccionado especialmente para este trabalho. Para poder analisar os resultados a seguir foram utilizadas as seguintes ferramentas estatísticas: média, desvio padrão, máximo, mínimo, o Teste t para comparação de médias e o teste não paramétrico Mann-Whitney para a comparação das medianas. Os softwares utilizados foram o Excel e o Minitab. Os resultados obtidos mostram que (1) ainda que de forma fraca, o ciúme é um agente de profecia auto-realizadora para a infidelidade (r= 0,25; 90 gl; p< 0,05 e r= 0,21; 90 gl; p< 0,05), de tal forma que há uma associação entre a infidelidade em ambos os parceiros (r=0,36; 45 gl; p< 0,05; r= 0,30; 45 gl; p< 0,05; r= 0,36; 45 gl; p< 0,01), (2) a partir dos dados analisados, pode-se afirmar que, para a nossa amostra, os sexos não diferem quanto à exibição do ciúme em termos de intensidade, (3) o sexo masculino tem tendência a trair mais do que o sexo feminino, provavelmente por razões ligadas à sexualidade (Teste W = 894,5; 826,0; 1496,5; p< 0.0001), (4) foi refutada a hipótese freudiana para a existência de um ciúme de natureza projetiva em homens e para as mulheres, (5) os comportamentos de infidelidade que mais se destacam entre os participantes são relacionados à rede internet (utilizar salas de bate papo, e-mails, mensagens on-line, dentre outros) e ter pensamentos relacionados aos comportamentos infiéis; ambos estão associados com o aumento das oportunidades que as pessoas têm de se engajarem em comportamentos amorosos infiéis, (6) há uma tendência, ainda que fraca, de quanto maior a auto-atribuição do escore “Nota física para si" menor será o número de comportamentos relacionados à infidelidade de seu(sua) parceiro(a) (r= -0,261; 90 gl; p< 0,01), (7) há uma tendência, ainda que fraca, de quanto a Nota física atribuída para o parceiro menor será o escore de ciúme, para ambas as etapas desta pesquisa (r= -0,217; 90 gl; p< 0,05 e r= - 0,205; 90 gl; p< 0,05, respectivamente), (8) nada se pode concluir com relação àqueles que se auto-atribuem notas quanto aos fatores psicológicos, em relação aos parceiros no que diz respeito ao ciúme, ou mesmo no que tange à infidelidade (9) quanto maior a idade dos participantes maior é o seu grau de comprometimento dos mesmos (r= 0,27; 90 gl; p< 0,01). Assim, pode-se concluir que os presentes resultados apoiaram algumas das hipóteses estabelecidas pelo autor desta pesquisa e foram consistentes com pesquisas anteriores, embora tenha refutado outras. Ainda pouco se conhece a respeito de quais os indivíduos são mais suscetíveis à infidelidade, mas este estudo permitiu identificar alguns fatores que promovem a infidelidade, algo que era muito pouco tratado pela literatura acadêmica até então. Dessa forma, o presente possibilitou uma melhor compreensão da dinâmica interpessoal amorosa, principalmente, referente a estes dois temas. Este estudo ainda, pode contribuir para outros estudos com o “Inventário de Comportamentos Relacionados à Infidelidade" que é útil para medir a freqüência de ocorrência de comportamentos amorosos infiéis. / Although the romantic jealousy and the loving infidelity are two important subjects that affect some human relationships and, also, a challenge for many of them, its origin mechanisms, action, association and consequences that can contribute to loving unfolding occur, haven’t had pretty well clarified. The present work has the intention of to verify possible associations between these two phenomena. Forty-five straight couples participated of this research with the average of 24.6 years enlisted by un announcement in the website of the University of São Paulo (USP). To evaluate the degrees of jealousy of the participants it was used the Scale of romantic jealousy - ECR (masculine and feminine versions) of Ramos, Yazawa & Salazar (1994). To evaluate the infidelity of the participants the “Inventory of Behaviors Related to the Infidelity" was especially elaborated for this work. To be able to analyze the results the following statistical tools had been used: average, standard deviation, maximum, minimum, the “T" test for comparison of averages and the test no parametric Mann-Whitney for the comparison of the medium ones. There were used Excel and Minitab soft wares. The results show that (1) although in a weak way, the jealousy is an agent of self-fulfilling prophecy for the infidelity (r= 0,25; 90 gl; p< 0,05 and r= 0,21; 90 gl; p< 0,05), in such a way that there is an association among the infidelity in both partners (r= 0,36; 45 gl; p< 0,05; r= 0,30; 45 gl; p< 0,05; r=0,36; 45 gl; p< 0,01), (2) starting from the analyzed data, it can be affirmed that, for our sample, the sexes don't differ as for the exhibition of the jealousy in intensity terms, (3) men usually tend to trail much more than women, maybe because of reasons connected to sexuality (“W" test = 894,5; 826,0; 1496,5; p< 0.0001), (4) the Freudian hypothesis was refuted for the existence of a jealousy of projective nature in men and for the women, (5) the infidelity behaviors that more they stand out among the participants are related to the use of the net internet (to use chats-rooms, e-mails, on-line messages, among other) and to have thoughts related to the behaviors infidels; both are associated with the increase of the opportunities that the people have of if they engage in behaviors loving infidels, (6) there is a tendency, although weak, of as larger the attribution of the score physical "Evaluation for itself" minor will be the number of behaviors related to his own infidelity (r= -0,261; 90 gl; p< 0,01), (7) there is a tendency even it is not strong, of as larger the physical Note attributed for the partner, smaller will be the jealousy score, for both stages of this research (r= -0,217; 90 gl; p<0,05 and r= - 0,205; 90 gl; p< 0,05, respectively), (8)There is nothing to conclude in relation to those people who give themselves superior or inferior grades, if the adopted criteria are the psychological factors, in relation to the partners in what it says respect to the jealousy, or even in what it refers to the infidelity (9) as the participants get older, the more they increase the level of commitment (r= 0,27; 90 gl; p< 0,01). So, it can be concluded that the results had supported some of the hypotheses established for the author of this research and had been consistent with previous research, although it has refuted others. There is a lot to know, regarding which individuals are more susceptible to the infidelity, but this research allowed, inside of its references, to identify and to discuss a little on some factors that promote the infidelity, something that has not been a common subject for the academic literature until then. This way, it was also possible to have a better understanding of the interpersonal love dynamics, mainly, referring to these two themes. This research can still contribute to other researches related to the “Inventory of Behaviors Related to the Infidelity" that is useful to measure the frequency the infidel love behaviors occur.

O principal objetivo deste trabalho é realizar uma leitura atenta que demonstre a importância do ciúme para a tessitura narrativa nos romances de Italo Svevo: Una vita (1892), Senilità (1898) e La coscienza di Zeno (1923). A partir da ordem de publicação de cada obra, pretende-se desvelar as relações amorosas, desnudando o modo como o ciúme apresenta-se nas histórias vividas pelos personagens. As diversas teorias que discorrem sobre o ciúme, ainda que de modos diferentes, convergem em um ponto, ou seja, no caráter triplo desse sentimento que terá, portanto, o triângulo como a forma geométrica que melhor o representa. Todavia, o ciúme será analisado neste estudo, sobretudo, à luz da teoria do filósofo francês, René Girard. Este trabalho ainda trata de duas questões fundamentais na obra de Svevo, intrinsicamente ligadas ao ciúme: o ambiente triestino, onde se desenrolam as histórias e o caráter inapto de seus protagonistas. / The main goal of this work is to produce an attentive reading that demonstrates the importance of jealousy shaping the narrative web in Italo Svevo\'s novels: Una vita (1892), Senilità (1898) e La coscienza di Zeno (1923). Following the chronological order of each piece, the intent is to unveil the amorous relationships by uncovering the manner jealousy is presented in characters\' histories. The diverse theories lecturing on jealousy -though may diverge in some aspects- end up converging in one: the triple aspect of the feeling, the triangle for its geometrical shape that very well represents it. However, jealousy will be taken in this study, most of all, enlightened by the french philosopher theory of René Girard. Furthermore, this thesis also deals with two important matters of Svevo\'s work, intrinsically linked to jealousy: the Triestian enviroment, where main characters\' storyline and inaptitude flourish.
