Attachment theory grows up: a developmental approach to pair bonds

What's love got to do with jealousy?

Romantic love and jealousy seem antagonistic, but the expression of both emotions have evolutionary functions that can go in the same direction of maintaining a relationship. Considering natural selection designed adaptations to solve the problems surrounding reproduction, then love and romantic jealousy are emotions aimed at staying cooperative for a period of time, where love solves the adaptive challenges of promoting pair bonding, cooperation, and protecting offspring; and jealousy is triggered by a threat or the loss of a valuable cooperative relationship, either on behalf of descendants in need of resources, or a close romantic bond. Consequently, understanding love and romantic jealousy points in the same adaptive functional domain of protecting a romantic pair bond. Specifically, love can be comprehended in two different ways and in regard to jealousy. First, conceiving love as the attachment to significant others one develops throughout lifetime, and secondly, it contemplates affective dependence. Results from a sample of single and committed individuals (n = 332) show the predicted positive correlation between attachment and jealousy as stable traits, consistent with previous literature. In addition, there is a non-significant and low correlation, respectively, between attachment and love as a measure of dependence. Furthermore, in the single participants group, jealousy was associated with love. The discussion emphasizes the need for expanding a functional account of love and jealousy as complementary emotions of our human affective endowment. Finally, it would be informative to study attachment as a relational trait and love as a specific affection for a romantic partner that could be manipulated to elucidate the functional design of jealousy.

Providing or receiving alloparental care promote partner preference and alter central oxytocin and dopamine systems in adult mandarin voles

Juveniles of cooperative breeding species usually remain in the natal area and provide care to younger siblings, a behavior considered one form of alloparenting in the natural condition. Previous studies have demonstrated the effects of providing or receiving alloparental care on adult behaviors, including anxiety-like behavior, social interaction, and parental behavior, but little is known about the influences on species-typical bonding behaviors, such as pair-bond formation. In this study, we explored this concept using socially monogamous mandarin voles (Lasiopodomys mandarinus). As the oxytocin (OT) and dopamine systems are involved in alloparental and pair-bonding behaviors, we also examined the levels of central OT and tyrosine hydroxylase (TH), as well as OT receptor (OTR) and dopamine D1-type and D2-type receptors (D1R and D2R) mRNA expression in the nucleus accumbens (NAcc) and amygdala to investigate the underlying mechanisms. Our results show that mandarin voles providing alloparental care to younger siblings displayed facilitation of partner preference formation, lower levels of OT expression in the paraventricular nucleus of the hypothalamus (PVN) and lateral hypothalamus (LH), and increased OTR and D2R mRNA expression in the NAcc compared to controls. Individuals receiving alloparental care also demonstrated facilitation of partner preference formation in adult voles. Additionally, alloparental care enhanced OT expression in the PVN, anterior medial preoptic nucleus (MPOAa), medial amygdala (MeA), and TH expression in the ventral tegmental area (VTA) and zona incerta (ZI). Furthermore, males displayed decreased D1R mRNA expression in the NAcc, whereas females showed slightly increased D2R expression in the amygdala. These results demonstrate that providing or received alloparental care can promote partner preference formation in monogamous species and that these changes are associated with altered OT and dopamine levels and their receptors in specific brain regions.

Romantic Attachment and Difficulties in Emotion Regulation on Dyadic Adjustment: A Comprehensive Literature Review

In romantic relationships, individual differences are determinant factors for relational quality. Specifically, romantic attachment (RA) and difficulties in emotional regulation influence each other and may have predictive potential for the perceived dyadic adjustment (DA) level. This paper aims to identify the developmental parallel between behavioral patterns built since childhood and the construction of the emotional regulation skills that characterize them. Our analysis was based on the attachment theory and the concepts of romantic relationship and DA. In this way, we sought to further the understanding of relationship dynamics, beyond the usual focus on a single element and on associative relationships, and by exploring other effects among the different dimensions of relational functioning. In particular, we explored the predictive ability of emotional regulation patterns (more flexible individual characteristics) in discriminating between RA styles (more perennial influences), and their impact on the quality of romantic relationships, in the anticipation of dyadic adjustment variations.

The Impact of Attachment on Depression in Married Seniors: Chain Mediating Effects of Self-Esteem and Rumination

In this study, we discuss the effects of attachment on depression and the mediating roles of self-esteem and rumination in Chinese seniors. We assessed 431 using the Experiences in Close Relationships Inventory, the Rosenberg Self-Esteem Scale, the Ruminative Responses Scale, and the Short Form of Center for Epidemiologic Studies Depression Scale. Both attachment anxiety and attachment avoidance significantly predicted depression in seniors. Attachment anxiety and attachment avoidance positively predicted rumination but negatively predicted self-esteem. Structural equation models showed that rumination and self-esteem fully mediated the effects of attachment anxiety and attachment avoidance on depression. The attachment of seniors is related to depression, and self-esteem and rumination have chain mediating effects between attachment and depression.

BRAND LOVE AMONG FEMALE CONSUMERS FOR FASHION CLOTHING

The purpose of this study is to investigate the association of brand anthropomorphism with anticipated separation distress through mediation of brand love among female consumers for fashion clothing brands. The conceptual research framework was empirically tested and data were collected through the questionnaire survey of 302 female consumers of fashion clothing brands in Pakistan. The structural equation modelling with partial least squares (SEM-PLS) is used to analyse the conceptual research framework. An explicit description is presented about the positive association of brand anthropomorphism with the anticipated separation distress through the mediation of brand love for ‘fashion clothing among female ’. This study has empirically proven the positive association of brand anthropomorphism with the anticipated separation distress of brand love among female consumers for fashion clothing. Additionally, this study enhances the knowledge of brand love in the context of female consumers and managers of clothing brands.
