Associations between significant head injury and persisting disability and violent crime in women in prison in Scotland, UK: a cross-sectional study.

Background: The prevalence of head injury is estimated to be as high as 55% in women in prison and might be a risk factor for violent offending, but evidence is equivocal. The extent of persisting disability is unknown, making decisions about service needs difficult. The UN recognises vulnerabilities in women in prison, but does not include head injury.

Chimpanzee 'folk physics': bringing failures into focus.

Differences between individuals are the raw material from which theories of the evolution and ontogeny of cognition are built. For example, when 4-year-old children pass a test requiring them to communicate the content of another's falsely held belief, while 3-year-olds fail, we know that something must change over the course of the third year of life. In the search for what develops or evolves, the typical route is to probe the extents and limits of successful individuals' ability.
