Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …

Social experience can alter how individuals cope with stressful events and contribute to individual differences in stress vulnerability. We have previously tested dominant and subordinate male Syrian hamsters (Mesocricetus auratus) in a conditioned defeat model and found that dominant individuals show reduced defeat-induced changes in behavior compared to subordinates. Dominant hamsters also show increased neural activation following social defeat stress in brain regions that regulate social behavior and coping with stress, including the medial amygdala (MeA). Because winning aggressive encounters generates a surge in plasma testosterone and androgen receptors are abundant in the MeA, we tested whether testosterone …

Anxiety and stress invoked by the second language classroom setting has the ability to cause numerous detrimental physiological changes which impair the learning process. A more natural, “immersion” type atmosphere is often desired when teaching a second language; however, this is not typically possible with college classes. Therefore, the addition of therapy dogs to college second language classes may be a beneficial solution since therapy dogs are frequently cited as having the ability to lower stress and anxiety in many different settings. Stroking and interacting with a dog may reduce many markers of stress, including blood pressure, heart rate, and …
