Expecting and Competing? Jealous Responses Among Pregnant and Nonpregnant Women

Karlijn Massar, Abraham P Buunk

Abstract

In the current study, we reasoned that when pregnant, women should be especially motivated to protect their reproductive investments as well as their pair bond and be vigilant about intrasexual competitors. To investigate this, pregnant women ( n = 66) and nonpregnant women ( n = 59; age M = 27.41, SD = 3.36) in committed relationships read a jealousy-evoking scenario that was accompanied by a picture of either an attractive or an unattractive woman, after which they indicated their jealousy about such a situation. Moreover, we asked whether a mate's emotional infidelity would evoke more jealousy than his sexual infidelity. The results showed that for pregnant women, both rivals evoked similar amounts of jealousy, whereas nonpregnant women's jealousy was mainly evoked by the attractive rival. Moreover, pregnant women indicated they would be most upset by their partner's emotional infidelity, and especially if they were previously exposed to the attractive rival. Nonpregnant women considered both types of infidelity equally upsetting. These results emphasize the adaptive function of jealousy and extend the literature on the influence of a rival's attractiveness on women's jealousy by focusing on the experiences of pregnant women.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
