5060.4 The role of medial frontal cortex in making decisions and changing tasks, M.
Rushworth, M. Walton, S. Kennerley, D. Bannerman, University of Oxford, Oxford, UK
The medial frontal cortex contains a number of areas but it has proved difficult to differentiate
their roles. Human neuroimaging and transcranial magnetic stimulation studies suggest that the
pre-SMA has a role in the selection of response sets even though it may not be important for the
selection of individual responses. The function may underlie its role during action sequences and
task switching. Neuroimaging studies show the cingulate cortex activated when subjects switch
tasks. Lesion studies, however, emphasize a cingulate role in coding response-outcome
associations and deciding whether it is worth responding at all given the expected outcome.

A model of behavioural regulation, derived from neuroimaging and neuropsychological case data,
will be described. It is suggested that the regulation of behaviour is dependent on a balance
between anterior and posterior structures in the brain. The anteroposterior dimension can be
conceptualized in terms of two major systems: (1) a medial component, represented primarily by
cingulate cortex and closely related systems, (2) a lateral component represented primarily by
anterior and posterior association neocortex. The model will be illustrated with functional
neuroimaging data, as well as neuropsychological information derived from common clinical
conditions such as dementia and stroke.

5061.1 Family factors predicting for post traumatic stress disorder, L. Hernández-Guzmán,
Universidad Nacional Autónoma de México, Mexico, Mexico
Only about 30% of those children exposed to the disaster develop PTSD. The aim of this study
was to identify the factors associated with the presence of psychopathology in such children. 263
children, living in a rural community, destroyed by flooding, were administered a structured
interview assessing PTSD symptoms in school-aged children, and one scale of the children
version of an inventory exploring family interaction, emotional and physical abuse, family
violence, peer relations, and adverse life events. Results show an influence of family relations on
the ability of the child to cope with adverse situations, such as natural disasters.
5061.2 Children at risk in Latin-American countries: innovative educational psychology
practices, M.R. Maluf, University of São Paulo, São Paulo, Brasil
Latin-American countries face problems derived from the extremely unequal wealth distribution
and the majority of their population are living in poverty. In this social context government
schools become a risk factor for children from underpriviledged families which do not succeed.
