Social Cognition How the mind operates in social contexts
Why is Social Cognition an Important Area of Research? �Studies the mechanisms that support the complex ability of one person to understand another person’s internal mental states
Why is Social Cognition an Important Area of Research? �Studies the mechanisms that support the complex ability of one person to understand another person’s internal mental states �One of the central goals of research is to study how we mentalize each other
Mentalization �Cognitive processes which permit one person to make accurate and rapid inferences about the internal states of another person
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC)
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC) �Temporo-parietal junction
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC) �Temporo-parietal junction �Precuneus/posterior cingulate
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC) �Temporo-parietal junction �Precuneus/posterior cingulate �These are the main 3
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC) �Temporo-parietal junction �Precuneus/posterior cingulate �Amygdala
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC) �Temporo-parietal junction �Precuneus/posterior cingulate �Amygdala �Superior temporal sulcus
What parts of the brain are involved in Mentalization? �Medial prefrontal cortex (MPFC) �Temporo-parietal junction �Precuneus/posterior cingulate �Amygdala �Superior temporal sulcus �Temporal poles
How do we know any of this? �Positron emission tomography (PET) �Functional magnetic resonance imaging (f. MRI)
There is controversy in using these techniques A few questions asked by critics: -Has neuroscience actually told us anything we could not have figured out with more established measures?
There is controversy in using these techniques A few questions asked by critics: -Has neuroscience actually told us anything we could not have figured out with more established measures? -Are the expenses and complications of neuroimaging techniques justified when they have only produced what appear to be novel observations?
Do social and nonsocial cognition draw on distinct or overlapping processes? �Fletcher et al. (1995) �The MPFC activated when reading stories involving social cognition
Do social and nonsocial cognition draw on distinct or overlapping processes? �Fletcher et al. (1995) �The MPFC activated when reading stories involving social cognition �Mitchell, Macrae, and Banaji (2004) �Social situations encode better because we use distinct mental processes for social cognition � MPFC again
BUT, WAIT!
BUT, WAIT! �Saxe and colleagues (e. g. , Saxe and Kanwisher, 2003) �Stories involving someone’s erroneous beliefs (social) and stories involving erroneous physical representations (nonsocial) both activate the right temporo-parietal junction
BUT, WAIT! �Saxe and colleagues (e. g. , Saxe and Kanwisher, 2003) �Stories involving someone’s erroneous beliefs (social) and stories involving erroneous physical representations (nonsocial) both activate the right temporo-parietal junction �So, there seems to be some overlap.
How do we mentalize? �Self-referencing model �Using our own mental states to inform our own opinion of another person’s mental states
How do we mentalize? �Self-referencing model �Using our own mental states to inform our own opinion of another person’s mental states �Rule-based model �Using a set of social rules to make inferences about another person’s mental states

Self-referencing model
Self-referencing model �Singer et al. (2004) �The anterior cingulate cortex activates for the person experiencing pain and the person watching
Self-referencing model �Singer et al. (2004) �The anterior cingulate cortex activates for the person experiencing pain and the person watching �Wicker et al. (2003) �The subregions of the anterior insula are activated in the person smelling the foul odor and the person watching the person smelling the foul odor
Primacy of social cognition
Primacy of social cognition �Parts of the brain related to social cognition seem to be discriminated for in the brain �MPFC, temporo-parietal junction, and the precuneus/posterior cingulate cortex
Primacy of social cognition �Parts of the brain related to social cognition seem to be discriminated for in the brain �MPFC, temporo-parietal junction, and the precuneus/posterior cingulate cortex �When we engage in nonsocial tasks, the brain has to actively dampen these areas.
We have VERY social brains
We have VERY social brains �Social cognitive functions seem to be a default mental state
