Based on promising results with adults, Acceptance and Commitment Therapy (ACT) presents as a treatment opportunity for depressed adolescents. We present a pilot study that compares ACT with treatment as usual (TAU), using random allocation of participants who were clinically referred to a psychiatric outpatient service. Participants were 30 adolescents, aged M = 14.9 (SD = 2.55), with 73.6% in the clinical range for depression. At posttreatment on measures of depression participants in the ACT condition showed significantly greater improvement statistically (d = 0.38), and 58% showed clinically reliable change with a response ratio of 1.59 in favor of ACT. Outcomes from 3-month follow-up data are tentative due to small numbers but suggest that improvement increased in magnitude. Measures of global functioning showed statistically significant improvement for both conditions, although clinical change measures favored only the ACT condition. The results support conducting a larger trial of ACT for the treatment of adolescent depression.
Children and adolescents with Asperger syndrome occasionally exhibit aggressive behavior against peers and parents. In a multiple baseline design across subjects, three adolescents with Asperger syndrome were taught to use a mindfulness-based procedure called Meditation on the Soles of the Feet to control their physical aggression in the family home and during outings in the community. They were taught to shift the focus of their attention from the negative emotions that triggered their aggressive behavior to a neutral stimulus, the soles of their feet. Prior to training in the mindfulness-based procedure the adolescents had moderate rates of aggression. During mindfulness practice, which lasted between 17 and 24 weeks, their mean rates of aggression per week decreased from 2.7, 2.5 and 3.2 to 0.9, 1.1, and 0.9, respectively, with no instances observed during the last 3 weeks of mindfulness practice. No episodes of physical aggression occurred during a 4-year follow-up. This study suggests that adolescents with Asperger syndrome may successfully use a mindfulness-based procedure to control their aggressive behavior.
People can experience great distress when a group to which they belong (in-group) is perceived to have committed an immoral act. We hypothesised that people would direct hostility toward a transgressing in-group whose actions threaten their self-image and evoke collective shame. Consistent with this theorising, three studies found that reminders of in-group transgression provoked several expressions of in-group-directed hostility, including in-group-directed hostile emotion (Studies 1 and 2), in-group-directed derogation (Study 2), and in-group-directed punishment (Study 3). Across studies, collective shame-but not the related group-based emotion collective guilt-mediated the relationship between in-group transgression and in-group-directed hostility. Implications for group-based emotion, social identity, and group behaviour are discussed.
Zen meditation, a Buddhist practice centered on attentional and postural self-regulation, has been speculated to bring about beneficial long-term effects for the individual, ranging from stress reduction to improvement of cognitive function. In this study, we examined how the regular practice of meditation may affect the normal age-related decline of cerebral gray matter volume and attentional performance observed in healthy individuals. Voxel-based morphometry for MRI anatomical brain images and a computerized sustained attention task were employed in 13 regular practitioners of Zen meditation and 13 matched controls. While control subjects displayed the expected negative correlation of both gray matter volume and attentional performance with age, meditators did not show a significant correlation of either measure with age. The effect of meditation on gray matter volume was most prominent in the putamen, a structure strongly implicated in attentional processing. These findings suggest that the regular practice of meditation may have neuroprotective effects and reduce the cognitive decline associated with normal aging.

Although the co-occurrence of negative affect and pain is well recognized, the mechanism underlying their association is unclear. To examine whether a common self-regulatory ability impacts the experience of both emotion and pain, we integrated neuroimaging, behavioral, and physiological measures obtained from three assessments separated by substantial temporal intervals. Our results demonstrated that individual differences in emotion regulation ability, as indexed by an objective measure of emotional state, corrugator electromyography, predicted self-reported success while regulating pain. In both emotion and pain paradigms, the amygdala reflected regulatory success. Notably, we found that greater emotion regulation success was associated with greater change of amygdalar activity following pain regulation. Furthermore, individual differences in degree of amygdalar change following emotion regulation were a strong predictor of pain regulation success, as well as of the degree of amygdalar engagement following pain regulation. These findings suggest that common individual differences in emotion and pain regulatory success are reflected in a neural structure known to contribute to appraisal processes.
The amygdalae are important, if not critical, brain regions for many affective, attentional and memorial processes, and dysfunction of the amygdalae has been a consistent finding in the study of clinical depression. Theoretical models of the functional neuroanatomy of both normal and psychopathological affective processes which posit cortical hemispheric specialization of functions have been supported by both lesion and functional neuroimaging studies in humans. Results from human neuroimaging studies in support of amygdalar hemispheric specialization are inconsistent. However, recent results from human lesion studies are consistent with hemispheric specialization. An important, yet largely ignored, feature of the amygdalae in the primate brain--derived from both neuroanatomical and electrophysiological data--is that there are virtually no direct interhemispheric connections via the anterior commissure (AC). This feature stands in stark contrast to that of the rodent brain wherein virtually all amygdalar nuclei have direct interhemispheric connections. We propose this feature of the primate brain, in particular the human brain, is a result of influences from frontocortical hemispheric specialization which have developed over the course of primate brain evolution. Results consistent with this notion were obtained by examining the nature of human amygdalar interhemispheric connectivity using both functional magnetic resonance imaging (FMRI) and positron emission tomography (PET). We found modest evidence of amygdalar interhemispheric functional connectivity in the non-depressed brain, whereas there was strong evidence of functional connectivity in the depressed brain. We interpret and discuss the nature of this connectivity in the depressed brain in the context of dysfunctional frontocortical-amygdalar interactions which accompany clinical depression.
BACKGROUND: Autism is a syndrome of unknown cause, marked by abnormal development of social behavior. Attempts to link pathological features of the amygdala, which plays a key role in emotional processing, to autism have shown little consensus. OBJECTIVE: To evaluate amygdala volume in individuals with autism spectrum disorders and its relationship to laboratory measures of social behavior to examine whether variations in amygdala structure relate to symptom severity. DESIGN: We conducted 2 cross-sectional studies of amygdala volume, measured blind to diagnosis on high-resolution, anatomical magnetic resonance images. Participants were 54 males aged 8 to 25 years, including 23 with autism and 5 with Asperger syndrome or pervasive developmental disorder not otherwise specified, recruited and evaluated at an academic center for developmental disabilities and 26 age- and sex-matched community volunteers. The Autism Diagnostic Interview-Revised was used to confirm diagnoses and to validate relationships with laboratory measures of social function. MAIN OUTCOME MEASURES: Amygdala volume, judgment of facial expressions, and eye tracking. RESULTS: In study 1, individuals with autism who had small amygdalae were slowest to distinguish emotional from neutral expressions (P=.02) and showed least fixation of eye regions (P=.04). These same individuals were most socially impaired in early childhood, as reported on the Autism Diagnostic Interview-Revised (P<.04). Study 2 showed smaller amygdalae in individuals with autism than in control subjects (P=.03) and group differences in the relation between amygdala volume and age. Study 2 also replicated findings of more gaze avoidance and childhood impairment in participants with autism with the smallest amygdalae. Across the combined sample, severity of social deficits interacted with age to predict different patterns of amygdala development in autism (P=.047). CONCLUSIONS: These findings best support a model of amygdala hyperactivity that could explain most volumetric findings in autism. Further psychophysiological and histopathological studies are indicated to confirm these findings.
In this article we examine the role of appeasement in human emotion, social practice, and personality. We first present an analysis of human appeasement. Appeasement begins when the conditions of social relations lead one individual to anticipate aggression from others, is expressed in submissive, inhibited behavior, which in turn evokes inferences and emotions in others that bring about social reconciliation. Our empirical review focuses on two classes of human appeasement: reactive forms of appeasement, including embarrassment and shame, which placate others after social transgressions; and anticipatory forms of appeasement, including polite modesty and shyness, which reduce the likelihood of social conflict and aggression. Our review of the empirical evidence indicates that embarrassment, shame, modesty, and shyness share the eliciting conditions, submissive behavior, and social consequences of appeasement. We conclude by discussing social processes that allow humans to appease one another, such as teasing, and those that prevent appeasement, such as legal and negotiation practices, to the benefit and detriment of human relations.

Background/Aim: Children with autism exhibit significant deficits in imitation skills, which impede the acquisition of more complex behavior and socialization. Imitation is often targeted early in intervention plans and continues to be addressed throughout the child’s treatment. The use of integrated approach to yoga therapy (IAYT) as a complementary therapy for children diagnosed with autism spectrum disorder (ASD) is rarely reported and little is known on the effectiveness of such therapies. This study investigated IAYT as a treatment method with children with ASD to increase imitative skills. Materials and Methods: Parents and six children with ASD participated in a 10-month program of 5-weekly sessions and regular practice at home. Pre, mid and post treatment assessments included observers and parent ratings of children’s imitation skills in tasks related to imitation skills such as gross motor actions, vocalization, complex imitation, oral facial movements and imitating breathing exercises. Results: Improvement in children’s imitation skills especially pointing to body, postural and oral facial movements. Parents reported change in the play pattern of these children with toys, peers and objects at home. Conclusions: This study indicates that IAYT may offer benefits as an effective tool to increase imitation, cognitive skills and social-communicative behaviors in children with ASD. In addition, children exhibited increased skills in eye contact, sitting tolerance, non-verbal communication and receptive skills to verbal commands related to spatial relationship.
This article presents 4 studies (N = 1,413) describing the development and validation of the Child and Adolescent Mindfulness Measure (CAMM). In Study 1 (n = 428), the authors determined procedures for item development and examined comprehensibility of the initial 25 items. In Study 2 (n = 334), they reduced the initial item pool from 25 to 10 items through exploratory factor analysis. Study 3 (n = 332) evaluated the final 10-item measure in a cross-validation sample, and Study 4 (n = 319) determined validity coefficients for the CAMM using bivariate and partial correlations with relevant variables. Results suggest that the CAMM is a developmentally appropriate measure with adequate internal consistency. As expected, CAMM scores were positively correlated with quality of life, academic competence, and social skills and negatively correlated with somatic complaints, internalizing symptoms, and externalizing behavior problems. Correlations were reduced but generally still significant after controlling for the effects of 2 overlapping processes (thought suppression and psychological inflexibility). Overall, results suggest that the CAMM may be a useful measure of mindfulness skills for school-aged children and adolescents.
This study compared the asymmetry of different features of brain electrical activity during the performance of a verbal task (word finding) and a spatial task (dot localization) that had been carefully matched on psychometric properties and accompanying motor activity. Nineteen right-handed subjects were tested. EEG was recorded from F3, F4, C3, C4, P3, and P4, referred to both CZ and computer-derived averaged-ears references, and Fourier transformed. Power in the delta, theta, alpha, and beta bands was computed. There were significant Task X Hemisphere effects in all bands for CZ-referenced data and for the alpha and beta bands for ears-referenced data. The effects were always either greater power suppression in the hemisphere putatively most engaged in task processing or greater power in the opposite hemisphere. Correlations between EEG and task performance indicated that CZ-referenced parietal alpha asymmetry accounted for the most variance in verbal task performance. Power within individual hemispheres or across hemispheres was unrelated to task performance. The findings indicate robust differences in asymmetrical brain physiology that are produced by well-matched verbal and spatial cognitive tasks.
The authors examined the hypothesis that rhesus monkeys with extreme right frontal electroencephalographic activity would have higher cortisol levels and would be more fearful compared with monkeys with extreme left frontal activity. The authors first showed that individual differences in asymmetric frontal electrical activity are a stable characteristic. Next, the authors demonstrated that relative right asymmetric frontal activity and cortisol levels are correlated in animals 1 year of age. Additionally, extreme right frontal animals had elevated cortisol concentrations and more intense defensive responses. At 3 years of age, extreme right frontal animals continued to have elevated cortisol concentrations. These findings demonstrate important relations among extreme asymmetric frontal electrical activity, cortisol levels, and trait-like fear-related behaviors in young rhesus monkeys.
Thirty-two participants were tested for both resting electroencephalography (EEG) and neuropsychological function. Eight one-minute trials of resting EEG were recorded from 14 channels referenced to linked ears, which was rederived to an average reference. Neuropsychological tasks included Verbal Fluency, the Tower of London, and Corsi's Recurring Blocks. Asymmetries in EEG alpha activity were correlated with performance on these tasks. Similar patterns were obtained for delta and theta bands. Factor analyses of resting EEG asymmetries over particular regions suggested that asymmetries over anterior scalp regions may be partly independent from those over posterior scalp regions. These results support the notions that resting EEG asymmetries are specified by multiple mechanisms along the rostral/caudal plane, and that these asymmetries predict task performance in a manner consistent with lesion and neuroimaging studies.
Terror management theory posits that people tend to respond defensively to reminders of death, including worldview defense, self-esteem striving, and suppression of death thoughts. Seven experiments examined whether trait mindfulness--a disposition characterized by receptive attention to present experience--reduced defensive responses to mortality salience (MS). Under MS, less mindful individuals showed higher worldview defense (Studies 1-3) and self-esteem striving (Study 5), yet more mindful individuals did not defend a constellation of values theoretically associated with mindfulness (Study 4). To explain these findings through proximal defense processes, Study 6 showed that more mindful individuals wrote about their death for a longer period of time, which partially mediated the inverse association between trait mindfulness and worldview defense. Study 7 demonstrated that trait mindfulness predicted less suppression of death thoughts immediately following MS. The discussion highlights the relevance of mindfulness to theories that emphasize the nature of conscious processing in understanding responses to threat.

In keeping with cognitive appraisal models of emotion, it was hypothesized that sadness and anger would exert different influences on causal judgments. Two experiments provided initial support for this hypothesis. Sad Ss perceived situationally caused events as more likely (Experiment 1) and situational forces more responsible for an ambiguous event (Experiment 2) than angry Ss, who, in contrast, perceived events caused by humans as more likely and other people as more responsible. Experiments 3, 4, and 5 showed that the experience of these emotions, rather than their cognitive constituents, mediates these effects. The nonemotional exposure to situational or human agency information did not influence causal judgments (Experiment 3), whereas the induction of sadness and anger without explicit agency information did (Experiments 4 and 5). Discussion is focused on the influence of emotion on social judgment.
The brain and the cardiovascular system influence each other during the processing of emotion. The study of the interactions of these systems during emotion regulation has been limited in human functional neuroimaging, despite its potential importance for physical health. We have previously reported that mental expertise in cultivation of compassion alters the activation of circuits linked with empathy and theory of mind in response to emotional stimuli. Guided by the finding that heart rate increases more during blocks of compassion meditation than neutral states, especially for experts, we examined the interaction between state (compassion vs. neutral) and group (novice, expert) on the relation between heart rate and BOLD signal during presentation of emotional sounds presented during each state. Our findings revealed that BOLD signal in the right middle insula showed a significant association with heart rate (HR) across state and group. This association was stronger in the left middle/posterior insula when experts were compared to novices. The positive coupling of HR and BOLD was higher within the compassion state than within the neutral state in the dorsal anterior cingulate cortex for both groups, underlining the role of this region in the modulation of bodily arousal states. This state effect was stronger for experts than novices in somatosensory cortices and the right inferior parietal lobule (group by state interaction). These data confirm that compassion enhances the emotional and somatosensory brain representations of others' emotions, and that this effect is modulated by expertise. Future studies are needed to further investigate the impact of compassion training on these circuits.
BACKGROUND: Studies using electroencephalogram (EEG) measures of activation asymmetry have reported differences in anterior asymmetry between depressed and nondepressed subjects. Several studies have suggested reciprocal relations between measures of anterior and posterior activation asymmetries. We hypothesized that depressed subjects would fail to show the normal activation of posterior right hemisphere regions in response to an appropriate cognitive challenge. METHODS: EEG activity was recorded from 11 depressed and 19 nondepressed subjects during the performance of psychometrically matched verbal (word finding) and spatial (dot localization) tasks. Band power was extracted from all epochs of artifact-free data and averaged within each condition. Task performance was also assessed. RESULTS: Depressed subjects showed a specific deficit in the performance of the spatial task, whereas no group differences were evident on verbal performance. In posterior scalp regions, nondepressed controls had a pattern of relative left-sided activation during the verbal task and relative right-sided activation during the spatial task. In contrast, depressed subjects failed to show activation in posterior right hemisphere regions during spatial task performance. CONCLUSIONS: These findings suggest that deficits in right posterior functioning underlie the observed impairments in spatial functioning among depressed subjects.
