Interspecies transmission of emotional information via chemosignals: from humans to dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>)

We report a study examining interspecies emotion transfer via body odors (chemosignals). Do human body odors (chemosignals) produced under emotional conditions of happiness and fear provide information that is detectable by pet dogs (Labrador and Golden retrievers)? The odor samples were collected from the axilla of male donors not involved in the main experiment. The experimental setup involved the co-presence of the dog’s owner, a stranger and the odor dispenser in a space where the dogs could move freely. There were three odor conditions [fear, happiness, and control (no sweat)] to which the dogs were assigned randomly. The dependent variables were the relevant behaviors of the dogs (e.g., approaching, interacting and gazing) directed to the three targets (owner, stranger, sweat dispenser) aside from the dogs’ stress and heart rate indicators. The results indicated with high accuracy that the dogs manifested the predicted behaviors in the three conditions. There were fewer and shorter owner directed behaviors and more stranger directed behaviors when they were in the “happy odor condition” compared to the fear odor and control conditions. In the fear odor condition, they displayed more stressful behaviors. The heart rate data in the control and happy conditions were significantly lower than in the fear condition. Our findings suggest that interspecies emotional communication is facilitated by chemosignals.     

Adjustment Profiles of Low-Income Caregivers from the United States and South Africa: Contrasts and Commonalities

Although low-income parents living in under-resourced communities in the United States and around the world face challenges, many do well while others struggle in one or more areas of functioning. The present study examined patterns of adjustment among maternal caregivers living in the United States (US) (N?=?320) and South Africa (SA) (N?=?324). Cluster analyses across four domains of functioning representing both positive and negative adjustment and conducted within country revealed similar patterns of adjustment, with a majority of caregivers (37.8% in the US; 47.5% in SA) landing in a “holding steady” pattern, exhibiting good but not exceptional adjustment. Other patterns of adjustment (three additional in the US sample; two additional in the SA sample) showed elevated impairment in somatic complaints, problems with alcohol, or life satisfaction. In both the US and SA, support from family, friends, and neighbors differentiated the adjustment profiles. Further, both current stressors within and outside of the family and previous stressors including direct and indirect exposure to violence discriminated caregivers who were “holding steady” from those who were struggling in one or more domains. Additionally, across both countries, caregivers who were “holding steady” evidenced less avoidant coping. Implications of this work for fostering resilience among caregivers and their children are discussed.     

Emotion-Focused Cognitive-Behavioral Therapy for Youth with Anxiety Disorders: A Randomized Trial

Difficulties with emotion regulation are a core feature of anxiety disorders (ADs) in children and adults. Interventions with a specific focus on emotion regulation are gaining empirical support. Yet, no studies to date have compared the relative efficacy of such interventions to existing evidence-based treatments. Such comparisons are necessary to determine whether emotion-focused treatments might be more effective for youth exhibiting broad emotion-regulation difficulties at pretreatment. This study examined an emotion-focused cognitive-behavioral therapy (ECBT) protocol in comparison to traditional cognitive-behavioral therapy (CBT) in a sample of children with a primary anxiety disorder diagnosis. Moderation analyses examined whether children with higher levels of emotion dysregulation at pretreatment would show greater levels of improvement in ECBT than CBT. Ninety-two youth ages 7 to 12 years (58% male) with a primary diagnosis of separation anxiety disorder, generalized anxiety disorder, or social phobia were included. Participants were randomly assigned to ECBT or CBT. Results showed that youth in both conditions demonstrated similar improvements in emotion regulation and that pretreatment levels of emotion dysregulation did not moderate treatment outcomes. Additional analyses showed that ECBT and CBT were similarly effective on diagnostic, severity, and improvement measures. Future work is needed to further explore the ways that emotion regulation is related to treatment outcome for anxious youth.
