W9. SOCIAL ISOLATION INDUCES TRANSCRIPTOMIC CHANGES IN FEMALE MOUSE HIPPOCAMPUS

ABSTRACT Background and objective Bruce et al had shown, during 1959 to 1968, that if, 24 hours after mating, a mouse belonging to a different inbred strain than the stud mouse was placed in the cage of the female mouse, partitioned in such a way that no physical contact of the nonstud male with the female was possible, pregnancy was blocked. We, therefore, decided to determine whether, by analogy with mice, isolation of women from all other men except the husband, for 3 days after embryo transfer following in vitro fertilization (IVF) or intracycloplasmic sperm injection (ICSI), increases the establishment of pregnancy. Method We isolated randomly selected 729 women from all other men except the husband for 3 full days after embryo transfer following IVF/ICSI, and followed them to the end of pregnancy; 1005 randomly selected women who were treated similarly but not isolated served as the control group. Results The establishment of clinical pregnancy as well as live births were more than 50% higher in the isolated group than in the control. Conclusion The social isolation as mentioned above could substantially increase the success rates in IVF or ICSI. While the exact mechanism of this phenomenon is yet to be understood, one possible explanation may be, by analogy with mice, an olfactory block to implantation.

Emotional Events

Abstract. After experiencing an emotional event, people either seek out others’ presence (social affiliation) or avoid others’ presence (social isolation). The determinants and effects of social affiliation are now well-known, but social psychologists have not yet thoroughly studied social isolation. This study aims to ascertain which motives and corresponding regulation strategies participants report for social isolation following negative emotional events. A group of 96 participants retrieved from memory an actual negative event that led them to temporarily socially isolate themselves and freely listed up to 10 motives for social isolation. Through semantic categorization of the 423 motives reported by the participants, we found that “cognitive clarification” and “keeping one’s distance” – that is, the need for cognitive regulation and the refusal of socioaffective regulation, respectively – were the most commonly and quickly reported motives for social isolation. We discuss the findings in terms of ideas for future studies aimed at clarifying the role of social isolation in health situations.

The Relationship

Humans are social animals; consequently, a lack of social ties affects individuals’ health negatively. However, the desire to belong differs between individuals, raising the question of whether individual differences in the need to belong moderate the impact of perceived social isolation on health. In the present study, 77 first-year university students rated their loneliness and health every 6 weeks for 18 weeks. Individual differences in the need to belong were found to moderate the relationship between loneliness and current health state. Specifically, lonely students with a high need to belong reported more days of illness than those with a low need to belong. In contrast, the strength of the need to belong had no effect on students who did not feel lonely. Thus, people who have a strong need to belong appear to suffer from loneliness and become ill more often, whereas people with a weak need to belong appear to stand loneliness better and are comparatively healthy. The study implies that social isolation does not impact all individuals identically; instead, the fit between the social situation and an individual’s need appears to be crucial for an individual’s functioning.
