Perceived Stress, Thinking Style and Paranormal Belief

Paranormal beliefs often become stronger in times of stress. Such beliefs have also been found to vary in accordance with thinking style, whereby stronger beliefs are often observed in experiential thinkers. Little research, however, has explored the interaction between perceived stress and thinking style. 82 males and females aged 18 to 62 years (mean = 29.96 ± 12.53 years) completed measures of perceived stress, thinking style (rational and experiential) and paranormal belief. The results revealed stronger beliefs in experiential thinkers, compared with those with a rational thinking style. Perceived stress alone, was not a prominent predictor of belief but the combination of stress and thinking style, specifically high perceived stress with a rational thinking style, significantly predicted greater global paranormal belief, belief in superstition, traditional religious belief, and belief in psi. High perceived stress appeared to facilitate belief in rational thinkers as conversely, belief was lowest in rational thinkers under conditions of low-perceived stress. These findings suggest that stress may lower the propensity for rational thinking and consequently, encourage belief in scientifically unsubstantiated phenomena. This interaction may have implications for coping during stressful situations

Analyses of pig genomes provide insight into porcine demography and evolution

For 10,000 years pigs and humans have shared a close and complex relationship. From domestication to modern breeding practices, humans have shaped the genomes of domestic pigs. Here we present the assembly and analysis of the genome sequence of a female domestic Duroc pig (Sus scrofa) and a comparison with the genomes of wild and domestic pigs from Europe and Asia. Wild pigs emerged in South East Asia and subsequently spread across Eurasia. Our results reveal a deep phylogenetic split between European and Asian wild boars ∼1 million years ago, and a selective sweep analysis indicates selection on genes involved in RNA processing and regulation. Genes associated with immune response and olfaction exhibit fast evolution. Pigs have the largest repertoire of functional olfactory receptor genes, reflecting the importance of smell in this scavenging animal. The pig genome sequence provides an important resource for further improvements of this important livestock species, and our identification of many putative disease-causing variants extends the potential of the pig as a biomedical model
