It works to combine the insights of psychology, especially psychoanalysis, with the research methodology of the social sciences and humanities to understand the emotional origin of the behavior of individuals, groups and nations, past and present.
Work in the field has been done in the areas of childhood, creativity, dreams, family dynamics, overcoming adversity, personality, political and presidential psychobiography.
Psychohistorians claim to derive many of its concepts from areas that are perceived to be ignored by conventional historians and anthropologists as shaping factors of human history, in particular, the effects of parenting practice and child abuse.
[7] Psychohistorians have argued that psychohistory is a separate field of scholarly inquiry with its own particular methods, objectives and theories, which set it apart from conventional historical analysis and anthropology.
Some historians, social scientists and anthropologists have, however, argued that their disciplines already describe psychological motivation and that psychohistory is not, therefore, a separate subject.
[8] Psychohistorians maintain that the difference is one of emphasis and that, in conventional study, narrative and description are central, while psychological motivation is hardly touched upon.
[10] They maintain that what constitutes child abuse is a matter of objective fact, and that some of the practices which mainstream anthropologists apologize for (e.g., sacrificial rituals) may result in psychosis, dissociation and magical thinking.
[11] Psychohistorians have written much about changes in the human psyche through history; changes that they believe were produced by parents, and especially the mothers' increasing capacity to empathize with their children.
[citation needed] The major psychogenic modes described by deMause are:[12][13] On the other hand, the relatively more enlightened Greeks and Romans exposed some of their babies ("late" infanticidal childrearing).
An example of this are reports of selective abortion (and sometimes exposure of baby girls)[15] especially in China, Korea, Taiwan, Singapore, Malaysia, India, Pakistan, New Guinea, and many other developing countries in Asia and North Africa,[16] regions in which millions of women are "missing".
[14] According to the psychogenic theory, since Neanderthal man most tribes and families practiced infanticide, child mutilation, incest and beating of their children throughout prehistory and history.
The further back in history one goes, the lower the level of childcare, and the more likely children are to be killed, abandoned, beaten, terrorized and sexually abused.
In 1973, historian Hugh A. Trevor-Roper dismissed the field of psychohistory entirely in response to the publication of Walter Langer's The Mind of Adolf Hitler.
However, deMause received criticism for his repeated, detailed descriptions on childhood atrocities:[31] The reader is doubtless already familiar with examples of these psychohistorical "abuses."
There is a significant difference, however, between the well-meaning and serious, if perhaps simplistic and reductionistic, attempt to understand the psychological in history and the psychohistorical expose that can at times verge on historical pornography.
