Healthy Clinical Trial
Official title:
The Impact of Familiarity and Emotional Attachment on the Visual Processing of Faces
This study uses functional magnetic resonance imaging (fMRI) to look at brain activity while
patients view pictures of people's faces that they are familiar with or have emotional
attachment to.
The functional MRI (fMRI) procedure allows researchers to "see the brain at work." It uses
the same powerful magnetic fields and weak electromagnetic radiation (radiowaves) as
standard structural MRI. However, functional MRI can also show areas of increased blood
flow, which relates to increased activity by brain cells.
This research study builds on previous studies that identified specific areas of the brain
that are activated by visual stimuli showing faces. However, previous research used
anonymous faces as stimuli. This study will use faces of individuals known to the patient.
There are three experiments that will be conducted in the study;
1. Experiment 1 will attempt to determine the effects of familiarity of the photographed
face on brain activity patterns. Patients will view familiar faces, the faces of close
friends and relatives, and the faces of famous people.
2. Experiment 2 will look at how maternal attachment affects the response to visual
stimuli. Mothers will view pictures of their first born child, as well as those of
familiar children to whom they are not related, unfamiliar children, and unfamiliar
adults.
3. Experiment 3 will explore the effects of interpersonal attachment and loss on response
to visual stimuli. In this experiment, bereaved spouses will view pictures of their
deceased spouse, those of living family members, and those of unfamiliar people.
This functional magnetic resonance imaging protocol uses a face recognition activation task to ascertain how brain activation patterns differ depending on the subject's familiarity with, and emotional attachment to, the person depicted in the visual stimulus. In a series of studies, subjects will view unfamiliar and familiar (including personally familiar and famous) faces; mothers will view pictures of their own child and those of familiar and unfamiliar children; and bereaved and non-bereaved spouses will view pictures of their spouse, other family members, and unfamiliar people. The use of emotionally significant faces as activation stimuli may help to elucidate the neural circuitry underlying interpersonal attachment and psychological responses to loss. ;
