Childhood Exposure

Abstract Being able to control oneself in emotionally upsetting situations is essential for good relationship functioning. According to life history theory, childhood exposure to harshness and unpredictability should forecast diminished emotional control and lower relationship quality. We examined this in three studies. In Studies 1 and 2, greater childhood unpredictability (frequent financial, residential, and familial changes), but not harshness (low SES), was associated with lower emotional control in adolescents (N = 1041) and adults (N = 327). These effects were stronger during the participants’ reproductive years. Moreover, in Study 2, greater childhood unpredictability was indirectly associated with lower relationship quality through lower emotional control. In study 3, we leveraged the Minnesota Longitudinal Study of Risk and Adaptation (N = 160). Greater early-life unpredictability (ages 0–4) prospectively predicted lower relationship quality at age 32 via lower emotional control at the same age. This relation was serially mediated by less supportive observed early maternal care (ages 1.5–3.5) and insecure attachment representations (ages 19 and 26). Early unpredictability also predicted greater observed emotional distress during conflict interactions with romantic partners (ages 19–36). These findings point to the role of emotional control in mediating the effects of unpredictable childhood environments on relationship functioning in adulthood.

The Relationship

BackgroundA growing body of research has investigated associations between insecure attachment styles and psychosis. However, despite good theoretical and epidemiological reasons for hypothesising that insecure attachment may be specifically implicated in paranoid delusions, few studies have considered the role it plays in specific symptoms.MethodWe examined the relationship between attachment style, paranoid beliefs and hallucinatory experiences in a sample of 176 people with a diagnosis of schizophrenia spectrum disorders and 113 healthy controls. We also investigated the possible role of negative self-esteem in mediating this association.ResultsInsecure attachment predicted paranoia but not hallucinations after co-morbidity between the symptoms was controlled for. Negative self-esteem partially mediated the association between attachment anxiety and clinical paranoia, and fully mediated the relationship between attachment avoidance and clinical paranoia.ConclusionsIt may be fruitful to explore attachment representations in psychological treatments for paranoid patients. If future research confirms the importance of disrupted attachment as a risk factor for persecutory delusions, consideration might be given to how to protect vulnerable young people, for example those raised in children's homes.

History Approach

Recent extensions to life history theory posit that exposure to environmental unpredictability during childhood should forecast negative parental behaviors in adulthood. In the current research, this logic was extended to co-parental behaviors, which refer to how parents coordinate, share responsibility, and support each other’s parental efforts. The effects of early-life unpredictability on individual and dyadic co-parental functioning were examined in a sample of 109 families (two parents and their firstborn child) who were followed longitudinally from before the child’s birth until the age of two. Greater early-life unpredictability (family changes, residential changes, and parents’ occupational changes by age 8) experienced by mothers, but not fathers, predicted more negative co-parental behaviors in triadic observations 6 months post birth, and lower couple-reported co-parenting quality assessed 3, 9, 18, and 24 months post birth. These effects were not explained by parents’ childhood socioeconomic status or current relationship quality. These findings highlight the role of mothers in shaping co-parenting relationships and how these relationships might be influenced by mothers’ early-life experiences.

Using Data

Intercultural romantic relationships and multicultural families have increased in the United States and worldwide. Researchers have found that intercultural couples report high rates of conflict and relationship instability, which may be partly explained by differences between partners in relationship goals (e.g., how much intimacy is desired and how to approach conflict). Using data from 40 intercultural couples (N = 80), we test whether greater similarity in relationship goals between romantic partners is related to greater perceived partner responsiveness and, thereby, greater relationship quality. By means of Bayesian analyses, our results suggest that similarity of relationship goals is associated with both perceived responsiveness and relationship quality, but without evidence of mediation. Our results show that cultural similarities and differences exist in relationship goals in intercultural couples, and they are connected to relationship functioning. This information can be used to assist clinicians in understanding the interpersonal processes that make-up healthy relationship functioning in intercultural couples.

The Relationship

Life-history theory predicts a trade-off between offspring size and number. However, the role of intra-litter phenotypic variation in shaping this trade-off is often disregarded. We compared the strength of the relationship between litter size and mass from the perspective of the lightest and the heaviest yearling offspring in 110 brown bear litters in Sweden. We showed that the mass of the lightest yearlings decreased with increasing litter size, but that the mass of the heaviest yearling remained stable, regardless of litter size. Consistent with a conservative reproductive strategy, our results suggest that mothers maintained a stable investment in a fraction of the litter, while transferring the costs of larger litter size to the remaining offspring. Ignoring intra-litter phenotypic variation may obscure our ability to detect a trade-off between offspring size and number.

AbstractAttachment theory may develop understanding of the occurrence and maintenance of persecutory delusions. This study investigates the role of dispositional attachment and contextually primed secure base attachment representations in the occurrence of paranoid thinking. Sixty participants were randomly allocated to one of three conditions: a secure attachment priming condition, a positive affect condition, or a neutral control condition. Following priming, all participants were exposed to a paranoia induction. State paranoia was measured at baseline and following the paranoia induction. Dispositional insecure attachment was associated with both trait and state paranoid thinking. Contrary to predictions, the secure attachment prime did not appear to buffer paranoid thinking and had a negative impact for participants with high levels of attachment anxiety, highlighting the potentially aversive effects of exposure to secure attachment material in those with existing insecure attachment styles.

AbstractHow do exposures to stress affect biobehavioral development and, through it, psychiatric and biomedical disorder? In the health sciences, the allostatic load model provides a widely accepted answer to this question: stress responses, while essential for survival, have negative long-term effects that promote illness. Thus, the benefits of mounting repeated biological responses to threat are traded off against costs to mental and physical health. The adaptive calibration model, an evolutionary–developmental theory of stress–health relations, extends this logic by conceptualizing these trade-offs as decision nodes in allocation of resources. Each decision node influences the next in a chain of resource allocations that become instantiated in the regulatory parameters of stress response systems. Over development, these parameters filter and embed information about key dimensions of environmental stress and support, mediating the organism's openness to environmental inputs, and function to regulate life history strategies to match those dimensions. Drawing on the adaptive calibration model, we propose that consideration of biological fitness trade-offs, as delineated by life history theory, is needed to more fully explain the complex relations between developmental exposures to stress, stress responsivity, behavioral strategies, and health. We conclude that the adaptive calibration model and allostatic load model are only partially complementary and, in some cases, support different approaches to intervention. In the long run, the field may be better served by a model informed by life history theory that addresses the adaptive role of stress response systems in regulating alternative developmental pathways.

Strategic Adjustment

Life-history theory predicts that optimal strategies of parental investment will depend on ecological and social factors, such as current brood value and offspring need. Parental care strategies are also likely to be mediated in part by the hypothalamic–pituitary–adrenal axis and glucocorticoid hormones. Here, we present an experiment in tree swallows ( Tachycineta bicolor ), a biparental songbird with wide geographical distribution, asking whether parental care is strategically adjusted in response to signals of offspring need and brood value and if so, whether glucocorticoids are involved in these adjustments. Using an automated playback system, we carried out playbacks of nestling begging calls specifically to females in two populations differing in their brood value: a northern population in Ontario, Canada (relatively higher brood value) and a southern population in North Carolina, USA (relatively lower brood value). We quantified female offspring provisioning rates before and during playbacks and plasma corticosterone levels (cort) once during late incubation and once immediately after playbacks. Females in both populations increased feeding rates temporarily during the first 2 h of playback but the increase was not sustained for the entire duration of playback (6 h). Cort levels from samples at the end of the playback did not differ between control females and females that received playbacks. However, females that had higher increases in cort between the incubation and nestling period had greater fledging success. These results suggest that females are able to strategically respond to offspring need, although the role of glucocorticoids in this strategic adjustment remains unclear.

Two Populations

Life-history strategies describe that ‘slow’- in contrast to ‘fast’-living species allocate resources cautiously towards reproduction to enhance survival. Recent evidence suggests that variation in strategies exists not only among species but also among populations of the same species. Here, we examined the effect of experimentally induced stress on resource allocation of breeding seabirds in two populations with contrasting life-history strategies: slow-living Pacific and fast-living Atlantic black-legged kittiwakes. We tested the hypothesis that reproductive responses in kittiwakes under stress reflect their life-history strategies. We predicted that in response to stress, Pacific kittiwakes reduce investment in reproduction compared with Atlantic kittiwakes. We exposed chick-rearing kittiwakes to a short-term (3-day) period of increased exogenous corticosterone (CORT), a hormone that is released during food shortages. We examined changes in baseline CORT levels, parental care and effects on offspring. We found that kittiwakes from the two populations invested differently in offspring when facing stress. In response to elevated CORT, Pacific kittiwakes reduced nest attendance and deserted offspring more readily than Atlantic kittiwakes. We observed lower chick growth, a higher stress response in offspring and lower reproductive success in response to CORT implantation in Pacific kittiwakes, whereas the opposite occurred in the Atlantic. Our findings support the hypothesis that life-history strategies predict short-term responses of individuals to stress within a species. We conclude that behaviour and physiology under stress are consistent with trade-off priorities as predicted by life-history theory. We encourage future studies to consider the pivotal role of life-history strategies when interpreting inter-population differences of animal responses to stressful environmental events.

Negative Effect

Most studies confirm that a combination of insecure attachment patterns in a couple has a negative effect on a romantic relationship. However, some research findings suggest otherwise. It is because they do not take account of relationship length as a moderating variable. The aim of this study was to examine the role of relationship length in predicting the effects of a combination of insecure attachment patterns on different aspects of its quality. The study involved 200 heterosexual couples. We used the Experiences in Close Relationships questionnaire to measure insecure attachment patterns (anxiety and avoidance) and the Couple Satisfaction Index-32 to determine relationship satisfaction. The other aspects of relationship quality (tenderness, communication, conflict behavior) were examined by means of the Partnership Questionnaire. The key results showed that with time the selected indicators of relationship quality deteriorate in a combination of anxious and avoidant patterns, while they improve in a combination of both anxious patterns.

Protection Against Infection

Wolbachia are maternally inherited bacterial endosymbionts that naturally infect a diverse array of arthropods. They are primarily known for their manipulation of host reproductive biology, and recently, infections with Wolbachia have been proposed as a new strategy for controlling insect vectors and subsequent human-transmissible diseases. Yet, Wolbachia abundance has been shown to vary greatly between individuals and the magnitude of the effects of infection on host life-history traits and protection against infection is correlated to within-host Wolbachia abundance. It is therefore essential to better understand the factors that modulate Wolbachia abundance and effects on host fitness. Nutrition is known to be one of the most important mediators of host–symbiont interactions. Here, we used nutritional geometry to quantify the role of macronutrients on insect– Wolbachia relationships in Drosophila melanogaster . Our results show fundamental interactions between diet composition, host diet selection, Wolbachia abundance and effects on host lifespan and fecundity. The results and methods described here open a new avenue in the study of insect– Wolbachia relationships and are of general interest to numerous research disciplines, ranging from nutrition and life-history theory to public health.
