All human relationships involve some form of cost and benefit and altruism forms the foundation upon which human relationships are built. In this paper, a taxonomy of human relationships in terms of altruism was constructed. In the proposed taxonomy, human relationships are categorized into three major groups: primary group, secondary group, and tertiary group. The primary group consists of mem...

What is altruism? Altruism is a type of social behaviour. From an evolutionary point of view, a behaviour is social if it has consequences for both the actor and another individual — the recipient. Social behaviours can be categorized according to whether their consequences for the actor and recipient are beneficial, increasing fitness, or costly, decreasing fitness (Figure 1). Altruism is when...

In the context of the trend toward delayed parenthood, this study examines whether older maternal age is associated with greater psychological maturity and whether greater psychological maturity provides any adaptive benefit during the transition to motherhood. A sample of 240 predominantly English-speaking Australian women in a metropolitan area expecting their 1st baby (mean age = 32.81 years...

In a community sample of 116 children, assessments of parent-child interaction, parent-child attachment, and various parental, child, and contextual characteristics at 15 and 28 months and at age 5 were used to predict externalizing behavior at age 5, as rated by parents and teachers. Hierarchical multiple regression analysis and path analysis yielded a significant longitudinal model for the pr...

If a visual observer moves through an environment, the patterns of light that impinge its retina vary leading to changes in sensed brightness. Spatial shifts of brightness patterns in the 2D image over time are called optic flow. In contrast to optic flow visual motion fields denote the displacement of 3D scene points projected onto the camera’s sensor surface. For translational and rotational ...

Altruism has long been taken to be the guiding principle of ethical organ donation in the UK, and has been used as justification for rejecting or allowing certain types of donation. We argue that, despite this prominent role, altruism has been poorly defined in policy and position documents, and used confusingly and inconsistently. Looking at how the term has been used over recent years allows ...

Can a generation’s discounting of future generations’ consumption utilities be interpreted as “pure” altruism towards future generations, that is, a concern that these are better off according to their likewise forward-looking preferences? It turns out that the answer is positive for many but not all discount functions used in the economics literature. In particular, traditional exponential dis...
