Single-trial EEG-fMRI reveals the dynamics of cognitive function

Two major non-invasive techniques in cognitive neuroscience, electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), have complementary advantages with regard to their spatial and temporal resolution. Recent hardware and software developments have made it feasible to acquire EEG and fMRI data simultaneously. We emphasize the potential of simultaneous EEG and fMRI recordings to pursue new strategies in cognitive neuroimaging. Specifically, we propose that, by exploiting the combined spatiotemporal resolution of the methods, the integration of EEG and fMRI recordings on a single-trial level enables the rich temporal dynamics of information processing to be characterized within spatially well-defined neural networks.     

Social perspective-taking skills in maltreated children and adolescents

The primary goal of this study was to assess the ability of maltreated school-age children and adolescents to understand the thoughts, feelings, and points of view of others. Level of egocentrism and social perspective-taking coordination were assessed in a group of 49 maltreated and 49 demographically matched nonmaltreated children. Twenty-six elementary and 23 high school students in each group were individually interviewed and their responses to hypothetical interpersonal situations coded for egocentricity and level of perspective-taking ability. The findings revealed that maltreated children and adolescents were more egocentric and delayed in their social perspective-taking development than their nonmaltreated peers and that they reported lower levels of global self-worth. However, differences within the group of maltreated children and adolescents emerged with regard to negotiating novel relationships, as those with fewer internalizing or externalizing symptoms exhibited better skills in this area than their peers who displayed more symptoms.

The Bulimia Workshop: A Unique Integration of Group Treatment Approaches

The time constraints of weekly group therapy and the slow evolution of group cohesion attenuate the direct confrontation that is essential with bulimic patients. Consequently, a three-phase, multidimensional group program was devised to accelerate the treatment process. Treatment begins with an intensive weekend workshop during which members formulate contracts for interrupting the binge–purge cycle and changing symptomatic behavior. During a follow-up session problems in fulfilling the contracts are dealt with and successes are reinforced, in the final phase, group members convene without their therapists to provide peer support, reevaluate contracts, and share feelings regarding treatment progress. The unique implications for treatment process and therapist interventions prompted by this new format are discussed, and preliminary research findings are highlighted.     

Predicting early emotion knowledge development among children of colour living in historically disinvested neighbourhoods: consideration of child pre-academic abilities,self-regulation,peer relations and parental education

ABSTRACT

Emotion knowledge, the ability to accurately perceive and label emotions, predicts higher quality peer relations, higher social competence, higher academic achievement, and fewer behaviour problems. Less is known, however, about predictors of early development of emotion knowledge. This study examines emotion knowledge development among children attending pre-Kindergarten and Kindergarten programmes in high-poverty urban schools. The study considers child pre-academic abilities, self-regulation, peer relations and parental education as predictors of emotion knowledge development over two years. The sample (n?=?1034) of children living in historically disinvested neighbourhoods was primarily Black (85%) and low-income (～61%). The sample was part of a longitudinal follow-up study of a cluster (school) randomised controlled trial in ten public elementary schools. Children’s emotion knowledge was assessed with a series of tasks three times over a two-year period. At baseline, parents and teachers reported on peer relations, children completed a test of pre-academic abilities, independent observers rated child self-regulation, and parents reported on their educational attainment. Results demonstrate that emotion knowledge increases over time, and pre-academic abilities, self-regulation, peer relations, and parent education independently predict children’s emotion knowledge. This study highlights multiple factors that predict emotion knowledge among primarily Black children living in historically disinvested neighbourhoods.     

The effect of very brief exposure on experienced fear after in vivo exposure

Two experiments tested the effect of exposure to masked phobic stimuli at a very brief stimulus onset asynchrony on reducing the subjective experience of fear caused by in vivo exposure to a feared object. In the main experiment, 35 spider-fearful and 35 non-fearful participants were identified with a questionnaire and a Behavioural Avoidance Test (BAT) with a live tarantula. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. They engaged in the BAT again immediately thereafter. They provided ratings of subjective fear at the end of each BAT (pre- and post-manipulation). Very brief exposure to images of spiders reduced the fearful group's and not the non-fearful group's experience of fear at the end of the BAT. This effect was replicated with another sample of 26 spider-fearful participants from the same population. Theoretical implications are discussed.     

When death thoughts lead to death fears: Mortality salience increases death anxiety for individuals who lack meaning in life

Research derived from terror management theory demonstrates that subtle reminders of mortality increase strivings for meaning. It is argued that such strivings reflect efforts to prevent the anxiety that death reminders may otherwise cause. However, no research has directly tested the assertions that subtle mortality primes increase death anxiety and perceptions of meaning in life moderate this effect. The current study examined these predictions. Meaning in life was measured, death cognition primed, and death anxiety assessed. A mortality prime increased death anxiety, but only for individuals who lack perceptions of meaning in life. Theoretical and applied implications are discussed.
