The Biological Bases of Conformity

The Biological Bases of Conformity

Humans are characterized by an extreme dependence on culturally transmitted information and recent formal theory predicts that natural selection should favor adaptive learning strategies that facilitate effective copying and decision making. One strategy that has attracted particular attention is conformist transmission, defined as the disproportionately likely adoption of the most common varia...

The Biological Bases of Empathy

Human beings are intrinsically social. Our survival critically depends on social interactions with others, the formation of alliances and accurate social judgments (Cacioppo, 2002). We are motivated to form and maintain positive and significant relationships (Baumeister & Leary, 1995), and most of our actions are directed toward or are responses to others (Batson, 1990). No single factor can ac...

The Biological and Evolutionist Bases of Ethics

Biological bases of dentin hybridization.

The aims of this study were threefold: (1) to characterize and quantify the number, diameter and surface area of exposed dentinal tubules on the cross section of the human coronal dentin; (2) to determine if any such differences in these properties arise in relation to the distance from the dentinoenamel junction; and (3) to evaluate whether such differences can influence dentin hybridization. ...

Physical and Biological Bases of Hearing

Sounds are produced because something vibrates in the environment. These vibrations are disturbances and their propagation is possible only because it happens in a material medium. This medium is usually air, but it could also be, for example, water or any other substance. If you are underwater and try to talk to someone, you will find that this is possible, but the carried message is far from ...
