Early life stress (ELS) and function of the hypothalamic-pituitary-adrenal axis predict later psychopathology. Animal studies and cross-sectional human studies suggest that this process might operate through amygdala-ventromedial prefrontal cortex (vmPFC) circuitry implicated in the regulation of emotion. Here we prospectively investigated the roles of ELS and childhood basal cortisol amounts in the development of adolescent resting-state functional connectivity (rs-FC), assessed by functional connectivity magnetic resonance imaging (fcMRI), in the amygdala-PFC circuit. In females only, greater ELS predicted increased childhood cortisol levels, which predicted decreased amygdala-vmPFC rs-FC 14 years later. For females, adolescent amygdala-vmPFC functional connectivity was inversely correlated with concurrent anxiety symptoms but positively associated with depressive symptoms, suggesting differing pathways from childhood cortisol levels function through adolescent amygdala-vmPFC functional connectivity to anxiety and depression. These data highlight that, for females, the effects of ELS and early HPA-axis function may be detected much later in the intrinsic processing of emotion-related brain circuits.
This study investigated differences in brain activation during meditation between meditators and non-meditators. Fifteen Vipassana meditators (mean practice: 7.9 years, 2 h daily) and fifteen non-meditators, matched for sex, age, education, and handedness, participated in a block-design fMRI study that included mindfulness of breathing and mental arithmetic conditions. For the meditation condition (contrasted to arithmetic), meditators showed stronger activations in the rostral anterior cingulate cortex and the dorsal medial prefrontal cortex bilaterally, compared to controls. Greater rostral anterior cingulate cortex activation in meditators may reflect stronger processing of distracting events. The increased activation in the medial prefrontal cortex may reflect that meditators are stronger engaged in emotional processing.
Considerable research has disclosed how cognitive reappraisals and the modulation of emotional responses promote successful emotion regulation. Less research has examined how the early processing of emotion-relevant stimuli may create divergent emotional response consequences. Mindfulness—a receptive, non-evaluative form of attention—is theorized to foster emotion regulation, and the present study examined whether individual differences in mindfulness would modulate neural responses associated with the early processing of affective stimuli. Focus was on the late positive potential (LPP) of the event-related brain potential to visual stimuli varying in emotional valence and arousal. This study first found, replicating past research, that high arousal images, particularly of an unpleasant type, elicited larger LPP responses. Second, the study found that more mindful individuals showed lower LPP responses to high arousal unpleasant images, even after controlling for trait attentional control. Conversely, two traits contrasting with mindfulness—neuroticism and negative affectivity—were associated with higher LPP responses to high arousal unpleasant images. Finally, mindfulness was also associated with lower LPP responses to motivationally salient pleasant images (erotica). These findings suggest that mindfulness modulates neural responses in an early phase of affective processing, and contribute to understanding how this quality of attention may promote healthy emotional functioning.
Individuals who experience early adversity, such as child maltreatment, are at heightened risk for a broad array of social and health difficulties. However, little is known about how this behavioral risk is instantiated in the brain. Here we examine a neurobiological contribution to individual differences in human behavior using methodology appropriate for use with pediatric populations paired with an in-depth measure of social behavior. We show that alterations in the orbitofrontal cortex among individuals who experienced physical abuse are related to social difficulties. These data suggest a biological mechanism linking early social learning to later behavioral outcomes.
Experienced Qigong meditators who regularly perform the exercises “Thinking of Nothing” and “Qigong” were studied with multichannel EEG source imaging during their meditations. The intracerebral localization of brain electric activity during the two meditation conditions was compared using sLORETA functional EEG tomography. Differences between conditions were assessed using t statistics (corrected for multiple testing) on the normalized and log-transformed current density values of the sLORETA images. In the EEG alpha-2 frequency, 125 voxels differed significantly; all were more active during “Qigong” than “Thinking of Nothing,” forming a single cluster in parietal Brodmann areas 5, 7, 31, and 40, all in the right hemisphere. In the EEG beta-1 frequency, 37 voxels differed significantly; all were more active during “Thinking of Nothing” than “Qigong,” forming a single cluster in prefrontal Brodmann areas 6, 8, and 9, all in the left hemisphere. Compared to combined initial–final no-task resting, “Qigong” showed activation in posterior areas whereas “Thinking of Nothing” showed activation in anterior areas. The stronger activity of posterior (right) parietal areas during “Qigong” and anterior (left) prefrontal areas during “Thinking of Nothing” may reflect a predominance of self-reference, attention and input-centered processing in the “Qigong” meditation, and of control-centered processing in the “Thinking of Nothing” meditation.
Objective To examine the effect of parental training on disturbed behavior of early childhood cases presented to the pediatricians. Methods The patients who reported in pediatric OPD of the Himalayan Institute of Medical Sciences, Dehradun, with complaints of low learning, poor memory, vertigo, speech problem, stress, headache, depression, adjustment problems, aggression, and hostile behavior were included in the study. Children aged 3 through 6 (N = 60), were screened through PBQ (Preschool Behavior Questionnaire), DST (developmental screening Test), and Vineland Social Maturity Scale (VSMS). Children included in the study had an average range of developmental quotient 85–90 (mean DQ = 87.5). Range of social quotient was 40–45 (mean SQ = 42.5). Twenty four fortnightly sessions of ‘parental training’ using the model of ‘Mindful Parenting’ were conducted. Single group t test method was applied in order to see the difference in mean of pre and post assessment of PBQ. Results After concluding parental training (after 24 sessions), mean difference of total disturbed behavior was found to be significant (t value: 5.31 > .05) Similarly, the mean difference of hostile/aggressive behavior (t value: 10.2 > .05), anxious behavior (t value: 18.5 > .05), and hyperactive/distractible behavior (t value: 1.97 > .05) were found to be significant. Conclusions These results provide some evidence in favor of parental training in managing behavioral problems occurring in early childhood. Instead of putting the child immediately on medication, parents can get training and prepare a plan to understand and make a change in child’s behavior leading to better health.
<p>A school-based program of mindful awareness practices (MAPs) was evaluated in a randomized control study of 64 second- and third-grade children ages 7–9 years. The program was delivered for 30 minutes, twice per week, for 8 weeks. Teachers and parents completed questionnaires assessing children's executive function immediately before and following the 8-week period. Multivariate analysis of covariance on teacher and parent reports of executive function (EF) indicated an interaction effect between baseline EF score and group status on posttest EF. That is, children in the MAPs group who were less well regulated showed greater improvement in EF compared with controls. Specifically, those children starting out with poor EF who went through the MAPs training showed gains in behavioral regulation, metacognition, and overall global executive control. These results indicate a stronger effect of MAPs on children with executive function difficulties. The finding that both teachers and parents reported changes suggests that improvements in children's behavioral regulation generalized across settings. Future work is warranted using neurocognitive tasks of executive functions, behavioral observation, and multiple classroom samples to replicate and extend these preliminary findings.</p>
In this study, we tested the validity of 2 popular assumptions about empathy: (a) empathy can be enhanced by oxytocin, a neuropeptide known to be crucial in affiliative behavior, and (b) individual differences in prosocial behavior are positively associated with empathic brain responses. To do so, we measured brain activity in a double-blind placebo-controlled study of 20 male participants either receiving painful stimulation to their own hand (self condition) or observing their female partner receiving painful stimulation to her hand (other condition). Prosocial behavior was measured using a monetary economic interaction game with which participants classified as prosocial (N = 12) or selfish (N = 6), depending on whether they cooperated with another player. Empathy-relevant brain activation (anterior insula) was neither enhanced by oxytocin nor positively associated with prosocial behavior. However, oxytocin reduced amygdala activation when participants received painful stimulation themselves (in the nonsocial condition). Surprisingly, this effect was driven by "selfish" participants. The results suggest that selfish individuals may not be as rational and unemotional as usually suggested, their actions being determined by their feeling anxious rather than by reason.
Social comparison can elicit emotions such as envy, which can affect social interactions. The emergence and development of such social emotions through ontogeny, and their influence on social interaction, are unknown. We tested 182 children from 7 to 13 years of age with a novel monetary reward-and-punishment task measuring envy and Schadenfreude (i.e., gloating or taking delight in someone else’s misfortune). Children were either rewarded or punished in a trial-by-trial evaluation of their performance on a speeded reaction time task. In a social condition, feedback of their own and a competitor’s performance was given for each trial. Afterward, children rated how they felt about the outcome. The ratings suggest that when children won, they felt better if the competitor lost instead of winning (i.e., Schadenfreude). Conversely, when children lost, they felt worse if the competitor won instead of losing (i.e., envy). Crucially, levels of envy and Schadenfreude decreased with age. We also studied how these emotions relate to social decisions made separately during three resource allocation paradigms. In each, children chose between two options that differed in the distribution of valuable tokens between themselves and an anonymous other. The combination of choices allowed the measurement of inequity aversion (i.e., equality for all) and spite (i.e., self-profit to maximal disadvantage of the other). We found an age-related increase in inequity aversion and decrease in spite. Crucially, age-related changes in both envy and Schadenfreude predicted the developmental change in equity-related decisions. These findings shed light on the development of social emotions and demonstrate their importance in the development of prosocial behavior in children.
OBJECTIVE: To examine yoga's effects on inner-city children's well-being. METHODS: This pilot study compared fourth- and fifth-grade students at 2 after-school programs in Bronx, New York. One program offered yoga 1 hour per week for 12 weeks (yoga) and the other program (non-yoga) did not. Preintervention and postintervention emotional well-being was assessed by Harter's Global Self-Worth and Physical Appearance subscales, which were the study's primary outcome measures. Secondary outcomes included other measures of emotional well-being assessed by 2 new scales: Perceptions of Physical Health and Yoga Teachings (including Negative Behaviors, Positive Behaviors, and Focusing/relaxation subscales). Preintervention and postintervention, physical wellbeing was assessed by measures of flexibility and balance. Subjective ratings ofyoga's effects on well-being were evaluated by an additional questionnaire completed by the yoga group only. RESULTS: Data were collected from 78% (n=39) and 86.5% (n=32) of potential yoga and non-yoga study enrollees. No differences in baseline demographics were found. Controlling for preintervention well-being differences using analysis of covariance, we found that children in the yoga group had better postintervention Negative Behaviors scores and balance than the non-yoga group (P < .05). The majority of children participating in yoga reported enhanced wellbeing, as reflected by perceived improvements in behaviors directly targeted by yoga (e.g., strength, flexibility, balance). CONCLUSIONS: Although no significant differences were found in the study's primary outcomes (global self-worth and perceptions of physical well-being), children participating in yoga reported using fewer negative behaviors in response to stress and had better balance than a comparison group. Improvements in wellbeing, specifically in behaviors directly targeted by yoga, were reported. These results suggest a possible role of yoga as a preventive intervention as well as a means of improving children's perceived well-being.
Occupational therapists use school-based yoga programs, but these interventions typically lack manualization and evidence from well-designed studies. Using an experimental pretest–posttest control group design, we examined the effectiveness of the Get Ready to Learn (GRTL) classroom yoga program among children with autism spectrum disorders (ASD). The intervention group received the manualized yoga program daily for 16 wk, and the control group engaged in their standard morning routine. We assessed challenging behaviors with standardized measures and behavior coding before and after intervention. We completed a between-groups analysis of variance to assess differences in gain scores on the dependent variables. Students in the GRTL program showed significant decreases (p < .05) in teacher ratings of maladaptive behavior, as measured with the Aberrant Behavior Checklist, compared with the control participants. This study demonstrates that use of daily classroomwide yoga interventions has a significant impact on key classroom behaviors among children with ASD.
The authors address 2 questions about embarrassment. First, Is embarrassment a distinct emotion? The evidence indicates that the antecedents, experience, and display of embarrassment, and to a limited extent its autonomic physiology, are distinct from shame, guilt, and amusement and share the dynamic, temporal characteristics of emotion. Second, What are the theoretical accounts of embarrassment? Three accounts focus on the causes of embarrassment, positioning that it follows the loss of self-esteem, concern for others' evaluations, or absence of scripts to guide interactions. A fourth account focuses on the effects of the remedial actions of embarrassment, which correct preceding transgressions. A fifth account focuses on the functional parallels between embarrassment and nonhuman appeasement. The discussion focuses on unanswered questions about embarrassment.
<p>Mindfulness meditation is an increasingly popular intervention for the treatment of physical illnesses and psychological difficulties. Using intervention strategies with mechanisms familiar to cognitive behavioral therapists, the principles and practice of mindfulness meditation offer promise for promoting many of the most basic elements of positive psychology. It is proposed that mindfulness meditation promotes positive adjustment by strengthening metacognitive skills and by changing schemas related to emotion, health, and illness. Additionally, the benefits of yoga as a mindfulness practice are explored. Even though much empirical work is needed to determine the parameters of mindfulness meditation's benefits, and the mechanisms by which it may achieve these benefits, theory and data thus far clearly suggest the promise of mindfulness as a link between positive psychology and cognitive behavioral therapies.</p>
<p>Abstract The authors examined the effect of a 6-week mind/body intervention on college students' psychological distress, anxiety, and perception of stress. One hundred twenty-eight students were randomly assigned to an experimental group (n = 63) or a waitlist control group (n = 65). The experimental group received 6 90-minute group-training sessions in the relaxation response and cognitive behavioral skills. The Symptom Checklist-90-Revised, Spielberger State-Trait Anxiety Inventory, and the Perceived Stress Scale were used to assess the students' psychological state before and after the intervention. Ninety students (70% of the initial sample) completed the postassessment measure. Significantly greater reductions in psychological distress, state anxiety, and perceived stress were found in the experimental group. This brief mind/body training may be useful as a preventive intervention for college students, according to the authors, who called for further research to determine whether the observed treatment effect can be sustained over a longer period of time.</p>
Belief in one's ability to change is an important cognitive variable related to treatment gains. This study investigated pretreatment expectancy for anxiety change and early homework compliance in relation to initial and total cognitive change in group cognitive-behavioral therapy (CBT) for anxiety. Participants, who met diagnostic criteria for at least 1 anxiety disorder, completed 10 sessions of group CBT. Early homework compliance mediated the relationship between expectancy for anxiety change at baseline and initial change in CBT. In addition, initial cognitive symptom improvement mediated the relationship between homework compliance and posttreatment outcome. These results suggest that expectancy for change is an important cognitive variable that may provide the initial impetus and subsequent momentum for therapeutic involvement and gains.

Many recent behavioral and neuroscientific studies have revealed the importance of investigating meditation states and traits to achieve an increased understanding of cognitive and affective neuroplasticity, attention and self-awareness, as well as for their increasingly recognized clinical relevance. The investigation of states and traits related to meditation has especially pronounced implications for the neuroscience of attention, consciousness, self-awareness, empathy and theory of mind. In this article we present the main features of meditation-based mental training and characterize the current scientific approach to meditation states and traits with special reference to attention and consciousness, in light of the articles contributed to this issue.
In this paper I discuss how expressive behavior relates to personality and psychopathology, integrating recent findings from my laboratory and the insights of Charles Darwin on this topic. In the first part of the paper I challenge the view, in part espoused by Darwin, that humans are equipped to convey only a limited number of emotions with nonverbal behavior. Our lab has documented displays for several emotions, including embarrassment, love, desire, compassion, gratitude, and awe, to name just a few states that previously were thought not to possess a distinct display. I then present an argument for how individual differences in emotion, although fleeting, shape the social environment. This argument focuses on the functions of nonverbal display: to provide information to others, to evoke responses, and to serve as incentives of preceding or ensuing social behavior. This reasoning sets the stage for the study of the relationships between personality, psychopathology, and expressive behavior, to which I turn in the final part of the paper. Here I show that basic personality traits (e.g., extraversion, agreeableness) and psychological disorders (e.g., externalizing disorder in children, autism) have expressive signatures that shape social interactions and environments in profound ways that might perpetuate and transmit the trait or disorder.
On the basis of the widespread belief that emotions underpin psychological adjustment, the authors tested 3 predicted relations between externalizing problems and anger, internalizing problems and fear and sadness, and the absence of externalizing problems and social-moral emotion (embarrassment). Seventy adolescent boys were classified into 1 of 4 comparison groups on the basis of teacher reports using a behavior problem checklist: internalizers, externalizers, mixed (both internalizers and externalizers), and nondisordered boys. The authors coded the facial expressions of emotion shown by the boys during a structured social interaction. Results supported the 3 hypotheses: (a) Externalizing adolescents showed increased facial expressions of anger, (b) on 1 measure internalizing adolescents showed increased facial expressions of fear, and (c) the absence of externalizing problems (or nondisordered classification) was related to increased displays of embarrassment. Discussion focused on the relations of these findings to hypotheses concerning the role of impulse control in antisocial behavior.
Although depressed mood is a normal occurrence in response to adversity in all individuals, what distinguishes those who are vulnerable to major depressive disorder (MDD) is their inability to effectively regulate negative mood when it arises. Investigating the neural underpinnings of adaptive emotion regulation and the extent to which such processes are compromised in MDD may be helpful in understanding the pathophysiology of depression. We report results from a functional magnetic resonance imaging study demonstrating left-lateralized activation in the prefrontal cortex (PFC) when downregulating negative affect in nondepressed individuals, whereas depressed individuals showed bilateral PFC activation. Furthermore, during an effortful affective reappraisal task, nondepressed individuals showed an inverse relationship between activation in left ventrolateral PFC and the amygdala that is mediated by the ventromedial PFC (VMPFC). No such relationship was found for depressed individuals, who instead show a positive association between VMPFC and amygdala. Pupil dilation data suggest that those depressed patients who expend more effort to reappraise negative stimuli are characterized by accentuated activation in the amygdala, insula, and thalamus, whereas nondepressed individuals exhibit the opposite pattern. These findings indicate that a key feature underlying the pathophysiology of major depression is the counterproductive engagement of right prefrontal cortex and the lack of engagement of left lateral-ventromedial prefrontal circuitry important for the downregulation of amygdala responses to negative stimuli.
Although individuals experience embarrassment as an unpleasant, negative emotion, the authors argue that expressions of embarrassment serve vital social functions, signaling the embarrassed individual's prosociality and fostering trust. Extending past research on embarrassment as a nonverbal apology and appeasement gesture, the authors demonstrate that observers recognize the expression of embarrassment as a signal of prosociality and commitment to social relationships. In turn, observers respond with affiliative behaviors toward the signaler, including greater trust and desire to affiliate with the embarrassed individual. Five studies tested these hypotheses and ruled out alternative explanations. Study 1 demonstrated that individuals who are more embarrassable also reported greater prosociality and behaved more generously than their less embarrassable counterparts. Results of Studies 2-5 revealed that observers rated embarrassed targets as being more prosocial and less antisocial relative to targets who displayed either a different emotion or no emotion. In addition, observers were more willing to give resources and express a desire to affiliate with these targets, and these effects were mediated by perceptions of the targets as prosocial.
The influence of approach and avoidance tendencies on affect, reasoning, and behavior has attracted substantial interest from researchers across various areas of psychology. Currently, frontal electroencephalographic (EEG) asymmetry in favor of left prefrontal regions is assumed to reflect the propensity to respond with approach-related tendencies. To test this hypothesis, we recorded resting EEG in 18 subjects, who separately performed a verbal memory task under three incentive conditions (neutral, reward, and punishment). Using a source-localization technique, we found that higher task-independent alpha2 (10.5-12 Hz) activity within left dorsolateral prefrontal and medial orbitofrontal regions was associated with stronger bias to respond to reward-related cues. Left prefrontal resting activity accounted for 54.8% of the variance in reward bias. These findings not only confirm that frontal EEG asymmetry modulates the propensity to engage in appetitively motivated behavior, but also provide anatomical details about the underlying brain systems.
BACKGROUND: The broad autism phenotype includes subclinical autistic characteristics found to have a higher prevalence in unaffected family members of individuals with autism. These characteristics primarily affect the social aspects of language, communication, and human interaction. The current research focuses on possible neurobehavioral characteristics associated with the broad autism phenotype. METHODS: We used a face-processing task associated with atypical patterns of gaze fixation and brain function in autism while collecting brain functional magnetic resonance imaging (fMRI) and eye tracking in unaffected siblings of individuals with autism. RESULTS: We found robust differences in gaze fixation and brain function in response to images of human faces in unaffected siblings compared with typically developing control individuals. The siblings' gaze fixations and brain activation patterns during the face processing task were similar to that of the autism group and showed decreased gaze fixation along with diminished fusiform activation compared with the control group. Furthermore, amygdala volume in the siblings was similar to the autism group and was significantly reduced compared with the control group. CONCLUSIONS: Together, these findings provide compelling evidence for differences in social/emotional processing and underlying neural circuitry in siblings of individuals with autism, supporting the notion of unique endophenotypes associated with the broad autism phenotype.
<p>Lower social class (or socioeconomic status) is associated with fewer resources, greater exposure to threat, and a reduced sense of personal control. Given these life circumstances, one might expect lower class individuals to engage in less prosocial behavior, prioritizing self-interest over the welfare of others. The authors hypothesized, by contrast, that lower class individuals orient to the welfare of others as a means to adapt to their more hostile environments and that this orientation gives rise to greater prosocial behavior. Across 4 studies, lower class individuals proved to be more generous (Study 1), charitable (Study 2), trusting (Study 3), and helpful (Study 4) compared with their upper class counterparts. Mediator and moderator data showed that lower class individuals acted in a more prosocial fashion because of a greater commitment to egalitarian values and feelings of compassion. Implications for social class, prosocial behavior, and economic inequality are discussed.</p>
