A majority of the literature on inbreeding avoidance was published at least 15 years ago, allowing for growth and development of the study through contemporary experimental methods and technology. Molecular techniques such as DNA fingerprinting have become more advanced and accessible, improving the efficiency and accuracy of measuring ...
The child-rearing practices of the kibbutz system are sometimes cited as an example of the Westermarck effect. Seen here are a group of children in Kibbutz Gan Shmuel , circa 1935–40. The Westermarck effect , also known as reverse sexual imprinting , is a psychological hypothesis that states that people tend not to be attracted to peers with ...
In evolutionary biology and psychology, such an ability is presumed to have evolved for inbreeding avoidance, [1] though animals do not typically avoid inbreeding. [2] An additional adaptive function sometimes posited for kin recognition is a role in kin selection. There is debate over this, since in strict theoretical terms kin recognition is ...
The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcrossing. [6] [7] Crossbreeding between populations sometimes has positive effects on fitness-related traits, [8] but also sometimes leads to negative effects known as outbreeding ...
The Synactive Theory of Newborn Behavioral Organization and Development [1] [2] (Synaction n., or Synactive adj. [from the Greek syn “together” and the Latin actio “action,” resulting in: “together in action”]) suggests that development of the human fetus, and later newborn, proceeds through the constant balancing of approach and avoidance behaviors, leading to: (1) a continuous ...
The Association for Behavior Analysis International has a special interest group for the behavior analysis of child development. Doctoral level behavior analysts who are psychologists belong to American Psychological Association's division 25: behavior analysis. The World Association for Behavior Analysis has a certification in behavior therapy.
John Locke. Early theories in child psychology were advocated by three famous theorists: John Locke, Jean Jacques Rousseau and Charles Darwin.They represent three famous schools of thought, namely the influence of the child’s environment, the role of the child’s cognitive development and the relationship with evolutionary origins of behavior.
Sequential hermaphroditism can also protect against inbreeding in populations of organisms that have low enough motility and/or are sparsely distributed enough that there is a considerable risk of siblings encountering each other after reaching sexual maturity, and interbreeding.
