Dread sensitivity in decisions about real and imagined electrical shocks does not vary by age.

Previous research has found age differences in intertemporal choices that involve trade-offs among events or outcomes that occur at different points in time, but these findings were mostly limited to hypothetical financial and consumer choices. We examined whether age effects extend to unpleasant physical experiences that elicit states of dread which lead participants to speed up the outcomes just to get them over with. We asked participants of different ages to choose among electrical shocks that varied in timing and intensity.

Trauma-Informed Hospice and Palliative Care.

This review highlights the need to integrate trauma-informed practices into hospice and palliative care. The pervasiveness of psychological trauma exposure has been established in the general population and among the elderly adults. Moreover, there is emerging evidence for multiple additional opportunities for exposure to psychological trauma at or near the end of life.

Subliminal trauma reminders impact neural processing of cognitive control in adults with developmental earthquake trauma: a preliminary report.

Little is known about the effects of developmental trauma on the neural basis of cognitive control among adults who do not have posttraumatic stress disorder. To examine this question, we used functional magnetic resonance imaging to compare the effect of subliminal priming with earthquake-related images on attentional control during a Stroop task in survivors of the 2008 Wenchuan earthquake in China (survivor group, survivors were adolescents at the time of the earthquake) and in matched controls (control group). We found that the survivor group showed greater activation in the left ventral anterior cingulate cortex (vACC) and the bilateral parahippocampal gyrus during the congruent versus incongruent condition, as compared to the control group.

Adolescent earthquake survivors' show increased prefrontal cortex activation to masked earthquake images as adults.

The great Sichuan earthquake in China on May 12, 2008 was a traumatic event to many who live near the earthquake area. However, at present, there are few studies that explore the long-term impact of the adolescent trauma exposure on adults' brain function. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate the brain activation evoked by masked trauma-related stimuli (earthquake versus neutral images) in 14 adults who lived near the epicenter of the great Sichuan earthquake when they were adolescents (trauma-exposed group) and 14 adults who lived farther from the epicenter of the earthquake when they were adolescents (control group).

Sex differences in the neural basis of false-belief and pragmatic language comprehension.

Increasing research evidence suggests that women are more advanced than men in pragmatic language comprehension and Theory of Mind (ToM), which is a cognitive component of empathy. We measured the hemodynamic responses of men and women while they performed a second-order false-belief (FB) task and a coherent story (CS) task. During the FB condition relative to the baseline (unlinked sentences [US]), we found convergent activity in ToM network regions, such as the temporoparietal junction (TPJ) bilaterally and precuneus, in both sexes.

Stress and the healthy adolescent brain: evidence for the neural embedding of life events.

Little is known about the long-term neural consequences of adverse life events for healthy adolescents, and this is particularly the case for events that occur after a putative stress-sensitive period in early childhood. In this functional magnetic resonance imaging study of healthy adolescents, we found that prior exposure to severe adverse life events was associated with current anxiety and with increased amygdala reactivity to standardized emotional stimuli (viewing of fearful faces relative to calm ones). Conjunction analyses identified multiple regions, including the amygdala, insula, and prefrontal cortex, in which reactivity to emotional faces covaried with life events as well as with current anxiety.

Autistic trait interactions underlie sex-dependent facial recognition abilities in the normal population.

Autistic face processing difficulties are either uniquely social or due to a piecemeal cognitive "style." Co-morbidity of social deficits and piecemeal cognition in autism makes teasing apart these accounts difficult. These traits vary normally, and are more separable in the general population, suggesting another way to compare accounts.

Harnessing repetitive behaviours to engage attention and learning in a novel therapy for autism: an exploratory analysis.

Rigorous, quantitative examination of therapeutic techniques anecdotally reported to have been successful in people with autism who lack communicative speech will help guide basic science toward a more complete characterisation of the cognitive profile in this underserved subpopulation, and show the extent to which theories and results developed with the high-functioning subpopulation may apply. This study examines a novel therapy, the "Rapid Prompting Method" (RPM). RPM is a parent-developed communicative and educational therapy for persons with autism who do not speak or who have difficulty using speech communicatively.

Allostasis and the developing human brain: explicit consideration of implicit models.

We previously used the theory of allostasis as the foundation for a model of the current stress process. This work highlighted the core emotional systems of the brain as the central mediator of the relationship between stress and health. In this paper, we extend this theoretical approach to consider the role of developmental timing.

More than maths and mindreading: sex differences in empathizing/systemizing covariance.

Empathizing-Systemizing theory posits a continuum of cognitive traits extending from autism into normal cognitive variation. Covariance data on empathizing and systemizing traits have alternately suggested inversely dependent, independent, and sex-dependent (one sex dependent, the other independent) structures. A total of 144 normal undergraduates (65 men, 79 women) completed the Reading the Mind in the Eyes, Embedded Figures, and Benton face recognition tests, the Autism Spectrum Quotient, and measures of digit length ratio and field of study; some also completed tests of motion coherence threshold (64) and go/no-go motor inhibition (128).

Allostasis and the human brain: Integrating models of stress from the social and life sciences.

We draw on the theory of allostasis to develop an integrative model of the current stress process that highlights the brain as a dynamically adapting interface between the changing environment and the biological self. We review evidence that the core emotional regions of the brain constitute the primary mediator of the well-established association between stress and health, as well as the neural focus of wear and tear due to ongoing adaptation. This mediation, in turn, allows us to model the interplay over time between context, current stressor exposure, internal regulation of bodily processes, and health outcomes.

Resilience after 9/11: multimodal neuroimaging evidence for stress-related change in the healthy adult brain.

Exposure to psychological trauma is common and predicts long-term physical and mental health problems, even in those who initially appear resilient. Here, we used multimodal neuroimaging in healthy adults who were at different distances from the World Trade Center on 9/11/01 to examine the neural mechanisms that may underlie this association. More than 3 years after 9/11/01, adults with closer proximity to the disaster had lower gray matter volume in amygdala, hippocampus, insula, anterior cingulate, and medial prefrontal cortex, with control for age, gender, and total gray matter volume.

Salivary cortisol levels and mood vary by lifetime trauma exposure in a sample of healthy women.

The authors examined the effects of lifetime trauma exposure on salivary cortisol and mood in a sample of women (N = 37) over 25 days before and after a stressful event. The sample excluded posttraumatic stress disorder (PTSD) and major depression and was divided into three groups: (a) no trauma, (b) prior trauma with no peritraumatic symptoms of acute distress, and (c) prior trauma with peritraumatic symptoms. Because results indicated no significant differences between groups one and two, they were combined for analysis.

The aftermath of 9/11: effect of intensity and recency of trauma on outcome.

Does trauma exposure have a long-term impact on the brain and behavior of healthy individuals? The authors used functional magnetic resonance imaging to assess the impact of proximity to the disaster of September 11, 2001, on amygdala function in 22 healthy adults. More than three years after the terrorist attacks, bilateral amygdala activity in response to viewing fearful faces compared to calm ones was higher in people who were within 1.5 miles of the World Trade Center on 9/11, relative to those who were living more than 200 miles away (all were living in the New York metropolitan area at time of scan).
