The Psychobiology of Childhood Temperament
The Psychobiology of Temperament: An fMRI Study

The purpose of this study is to use brain imaging technology to examine brain changes that occur in children when they are exposed to various kinds of emotional tasks and to determine if these changes are related to the child's temperament.

Studies suggest that the risk for developing mood and anxiety disorders in preschool children may be linked to differences in temperament. The relationship between temperament and risk or resilience may reflect the influences of brain activity on behavior at different stages of childhood development. Behavioral inhibition and mood or anxiety disorders have been linked to disturbances in the circuitry of several areas in the brain. However, the involvement of this circuitry in temperament remains unclear. This study will use functional magnetic resonance imaging (fMRI) to examine the function of different parts of the brain in children who have previously undergone temperament studies and have had their temperaments classified.

This study will comprise three clinic visits. At Visit 1, children and their parents will meet with study staff individually and together for psychiatric interviews. Children will undergo a physical examination, medical history, a urine drug test, and practice in an fMRI simulator. Saliva samples will be collected from the children and tests will be given to assess stage of puberty, temperament, intelligence, feelings, experiences, and behavior. Other visits include fMRI scans of the brain and other tasks.

Objectives: The goal of this proposal is to study temperament and risk-taking as

vulnerability factors for anxiety. Studies have documented that behaviorally inhibited

(BI) children are at risk for anxiety disorders. This vulnerability may be associated with

neural circuits underlying behavioral tendencies, such as components of the prefrontal

cortex (PFC), striatum, and amygdala. Regarding risk-taking behavior, certain high risk8

taking adolescents also carry enhanced vulnerability to anxiety. We use fMRI to examine

local activity in PFC, cingulate, amygdala, and striatum, and functional connectivity with

resting state methodology in two cohorts, one probing temperament and the other one

risk-taking.

Study Population: A total of 980 individuals (7-25 yo) will be studied. This

sample comprises 2 sets of study groups. First, the BI group includes individuals with

(1) high motor arousal/high negative affect in early infancy to novelty and sustained BI

(BI), (2) high motor arousal/high positive affect to novelty and sustained temperamental

exuberance (exuberant), (3) average levels of both reactivity/affect from infancy to

childhood (controls). Second, the risk-taking group includes 4 subgroups representing

the interaction of two levels of anxiety (low, high) and two levels of risk-taking (low,

high). Finally, a group of healthy individuals will be recruited as controls.

Design: Assessments will include psychiatric, behavioral, and

neuropsychological batteries. The protocol uses fMRI paradigms targeting different

emotional, social, cognitive, motivational, and learning processes during activation

studies, as well as the intrinsic function of the brain measured during a resting state.

Outcome Measures and Predictions: The main outcome measures are fMRI

BOLD signal changes, physiological, neuropsychological and behavioral variables. The

proposed fMRI studies will test 2 sets of hypotheses. The first refers to the BI cohort. BI

adolescents will exhibit (1) enhanced amygdala activation to mild threats (e.g., angry

facial), (2) PFC perturbations in associative learning, (3) abnormal fronto-amygdala

connectivity, (4) heightened striatal and inferior PFC activation to reward stimuli, (4)

unique neural patterns of attention bias and social challenges, (5) differential changes

with age as a function of BI status. The second set of hypotheses pertains to the risk32

taking cohort. (1) anxious adolescents will activate striatal regions in response to reward

more strongly than non-anxious adolescents; (2) risk-takers will also activate striatal

regions in response to reward more strongly than non-risk takers; (3) we expect an

interaction between risk-taking and anxiety-related factors, such as a potentiation of

striatal activation in anxious risk-takers, and a blunting of striatal activation in non37

anxious risk-takers. These effects will be uniquely altered by social stress. Finally,

repeat studies will be conducted with the BI cohort to examine stability/developmental

changes with time.
