The occurrence of positive selection in schizophrenia-associated GABRB2 suggests a broader impact of the gene product on population fitness. The present study considered the possibility of cognition-related GABRB2 involvement by examining the association of GABRB2 with psychosis and altruism, respectively representing psychiatric and psychological facets of social cognition. Four single nucleot...

It is understandable that remittances are larger if the migrant is more altruistic. However, remittances that the household expects to receive, i.e. expected remittances, depend not only on remittances by the migrant, who has already moved to the host county, but also on how likely it is that a household member, a potential migrant, actually migrates. Such a probability can also be affected by ...

Human beings routinely help strangers at costs to themselves. Sometimes the help offered is generous-offering more than the other expects. The proximate mechanisms supporting generosity are not well-understood, but several lines of research suggest a role for empathy. In this study, participants were infused with 40 IU oxytocin (OT) or placebo and engaged in a blinded, one-shot decision on how ...

In this study, researcher has tried out to know the status of altruism of students studying at senior secondary class on the basis of their gender. For this study the researcher has selected 200 students. The Altruism Scale prepared by Dr. S.N. Rai and Dr.Sanwat Singh (2004) has been used for the collection of data. The analysis techniques of SPSS-20 have been used by the researcher. The result...

We analyze the e¤ects of family ties on the incentives for production of e¤ort, where family ties are de…ned as a mixture of true and coerced altruism between family members. We model families as pairs of siblings. Each sibling exerts e¤ort in order to obtain output under uncertainty. A social norm dictates that a sibling with a high output must share a speci…ed amount of this output with his s...

The purpose of this study is to examine the relationships among social capital, altruism, common bond and identity, and revisit intention using social capital, altruism, and attachment theories. A total of 452 responses were generated from consumers 50 years of age and older (seniors), qualified as having used a social network site (SNS) for tourism-related products and services within the past...

The term population viscosity refers to limited dispersal, which increases the genetic relatedness of neighbors. This effect both supports the evolution of altruism by focusing the altruists' gifts on relatives of the altruist, and also limits the extent to which altruism may emerge by exposing clusters of altruists to stiffer local competition. Previous analyses have emphasized the way in whic...

Many animals show altruistic behavior by using signals, such as alarm calls. However, few study have discussed the coevolution of altruistic behavior and common words among agents, although many studies have discussed how altruism have evolved. In this study we performed simulation experiments in order to explore the condition of the emergence of altruistic behavior with common words between ag...

Institutional altruism in the form of a public-sector intervention and support for victims and social altruism generated by mutual aid and solidarity among citizens constitute a coming together in a crisis. This coming together and mutual support precipitate a decrease in crime rates during such an event. This paper presents an analysis of daily fluctuations in crime during the prolonged ice st...

Human altruism shaped our evolutionary history and pervades social and political life. There are, however, enormous individual differences in altruism. Some people are almost completely selfish, while others display strong altruism, and the factors behind this heterogeneity are only poorly understood. We examine the neuroanatomical basis of these differences with voxel-based morphometry and sho...
