Recent theoretical and empirical work has highlighted the role of domain-general, large-scale brain networks in generating emotional experiences. These networks are hypothesized to process aspects of emotional experiences that are not unique to a specific emotional category (e.g., “sadness,” “happiness”), but rather that generalize across categories. In this article, we examined the dynamic interactions (i.e., changing cohesiveness) between specific domain-general networks across time while participants experienced various instances of sadness, fear, and anger. We used a novel method for probing the network connectivity dynamics between two salience networks and three amygdala-based networks. We hypothesized, and found, that the functional connectivity between these networks covaried with the intensity of different emotional experiences. Stronger connectivity between the dorsal salience network and the medial amygdala network was associated with more intense ratings of emotional experience across six different instances of the three emotion categories examined. Also, stronger connectivity between the dorsal salience network and the ventrolateral amygdala network was associated with more intense ratings of emotional experience across five out of the six different instances. Our findings demonstrate that a variety of emotional experiences are associated with dynamic interactions of domain-general neural systems. 相似文献

Posttraumatic stress disorder (PTSD) is associated with executive functioning deficits, including disruptions in working memory (WM). Recent studies suggest that attention training reduces PTSD symptomatology, but the underlying neural mechanisms are unknown. We used high-density magnetoencephalography (MEG) to evaluate whether attention training modulates brain regions serving WM processing in PTSD. Fourteen veterans with PTSD completed a WM task during a 306-sensor MEG recording before and after 8 sessions of attention training treatment. A matched comparison sample of 12 combat-exposed veterans without PTSD completed the same WM task during a single MEG session. To identify the spatiotemporal dynamics, each group’s data were transformed into the time-frequency domain, and significant oscillatory brain responses were imaged using a beamforming approach. All participants exhibited activity in left hemispheric language areas consistent with a verbal WM task. Additionally, veterans with PTSD and combat-exposed healthy controls each exhibited oscillatory responses in right hemispheric homologue regions (e.g., right Broca’s area); however, these responses were in opposite directions. Group differences in oscillatory activity emerged in the theta band (4–8 Hz) during encoding and in the alpha band (9–12 Hz) during maintenance and were significant in right prefrontal and right supramarginal and inferior parietal regions. Importantly, following attention training, these significant group differences were reduced or eliminated. This study provides initial evidence that attention training improves aberrant neural activity in brain networks serving WM processing. 相似文献

Two cognitive tests were administered to typically developing children (36–67 months): the Mullen Scales of Early Learning (MSEL), which is appropriate for very young children and thus often used in research with atypical samples (e.g., children with Autism Spectrum Disorder), and the Kaufman Assessment Battery for Children (K-ABC). This was done in order to re-examine possible MSEL ceiling effects in a new sample and achieve a more in-depth understanding of these ceiling effects, if indeed present. Results indicated that among children ranging in age from 51 to 68 months, MSEL scores were significantly lower than K-ABC scores, and that with increasing age the number of children who completed the MSEL without establishing a ceiling level increased. Our results indicated that the MSEL scores are affected by ceiling effects and, therefore, the test underestimates cognitive abilities among older and more cognitively able children. 相似文献

Scene-Based Psychodramatic Family Therapy (SB-PFT) is an innovative treatment used with troubled adolescents and their parents to improve family relationships and reduce adolescents’ problematic behavior. It integrates the principles of family therapy, psychodrama, and multiple-family group methodology. This research is a pilot study to obtain empirical evidence on the SB-PFT therapeutic process by gauging the perception of change of troubled adolescents and their parents, and assess the perceived helpfulness of its methodology and techniques. Ten multiple-family intervention groups were drawn up, with 110 participants (63 adolescents and 47 parents), and we adopted a qualitative methodology with focus groups, using an inductive analysis of 290 active constructions of participant narratives. Concerning perception of change, the adolescents reported mainly gaining in social support, prosocial attitudes, keys to problem solving, and expression of emotions due to the treatment. The parents perceived improvement in social support, keys for educational practices, emotional well-being, and expression of emotions due to the treatment. Regarding the perceived helpfulness of methodology and techniques, both adolescents and parents highlighted the usefulness of the group methodology for gaining social support, relativizing the problem, and expressing emotions. Additionally, participants referred to role-playing and mirror techniques as the most useful techniques. In conclusion, this first study on SB-PFT presents and describes its treatment for troubled adolescents and their parents. The participants’ positive perception of their personal and relational change after treatment should serve to promote further studies with quantitative methodology in order to verify the effectiveness of SB-PFT treatment. 相似文献

In recent years, Cesar Chavez’s life and legacy have been subjected to increased scrutiny. The ensuing reevaluations of Chavez, wittingly or not, are matters of ethical, as well as historical and biographical, concern. This article has two aims. First, it reconstructs Chavez’s account of exemplarity and uses it to assess his legacy. Second, it provides an account of exemplarity situated within social practices. As I argue, exemplarity operates through social practices, rather than mystically as posited by a contagion model. The end result is an ethically nuanced reassessment of Chavez and an account of exemplarity that includes its social dimension. 相似文献

We explored whether rhesus monkeys (Macaca mulatta) share one important feature of human essentialist reasoning: the capacity to track category membership across radical featural transformations. Specifically, we examined whether monkeys – like children ( Keil, 1989 ) – expect a transformed object to have the internal properties of its original category. In two experiments, monkeys watched as an experimenter visually transformed a familiar fruit (e.g. apple) into a new kind of fruit (e.g. coconut) either by placing a fruit exterior over the original, or by removing an exterior shell and revealing the inside kind of fruit. The experimenter then pretended to place an inside piece of the transformed fruit into a box which the monkey was allowed to search. Results indicated that monkeys searched the box longer when they found a piece of fruit inconsistent with the inside kind, suggesting that the monkeys expected that the inside of the transformed fruit would taste like the innermost kind they saw. These results suggest that monkeys may share at least one aspect of psychological essentialism: They maintain category‐specific expectations about an object’s internal properties even when that object’s external properties change. These results therefore suggest that some essentialist expectations may emerge in the absence of language, and thus raise the possibility that such tendencies may emerge earlier in human development than has previously been considered. 相似文献
