Thinking too much: How young people experience rumination in the context of loneliness

The recent rise in the prevalence of loneliness, particularly among young adults, coupled with its deleterious effects on wellbeing, makes understanding the issue of pressing concern. As most research on loneliness has focused on older adults, this study explored how 48 young adults aged 18–24 subjectively experienced loneliness through free association-based interviews. Participants were sampled from the four most deprived boroughs in London, as area deprivation has been associated with a higher prevalence of loneliness. This facilitates understanding of contributors and consequences of loneliness within this demographic group. In particular, the focus is on rumination arising from loneliness; while the link between the two is well-established quantitively, research into rumination and the context of ruminative thoughts in the context of loneliness remains sparse. Thus, this study aimed to understand the subjective experience of rumination in young adults whilst they experienced loneliness. Thematic analysis of interviews using ATLAS.ti 9 revealed five themes capturing these experiences: ‘temporal experience of rumination’, ‘ruminating life and death’, ‘rumination related to others’, ‘outcomes of rumination’ and ‘coping with loneliness-related rumination’. Based upon knowledge of the nature and content of rumination, further research could devise models of rumination and interventions targeted at rumination such as mindfulness meditation, journaling and engaging in prosocial behaviour, to mitigate the adverse effects loneliness can have on wellbeing.     

Responsibility and Alternative Possibilities: The Use and Abuse of Examples

The philosophical debate over the compatibility between causaldeterminism and moral responsibility relies heavily on ourreactions to examples. Although we believe that there is noalternative to this methodology in this area of philosophy, someexamples that feature prominently in the literature are positivelymisleading. In this vein, we criticize the use that incompatibilistsmake of the phenomenon of ``brainwashing,' as well as the Frankfurt-styleexamples favored by compatibilists. We provide an instance of thekind of thought experiment that is needed to genuinely test thehypothesis that moral accountability and causal determinism arecompatible.     

Multi-limb coordination and rhythmic variability under varying sensory availability conditions in children with DCD

Children with Developmental Coordination Disorder (DCD) have sensory processing deficits; how do these influence the interface between sensory input and motor performance? Previously, we found that children with DCD were less able to organize and maintain a gross motor coordination task in time to an auditory cue, particularly at higher frequencies [Whitall, J., Getchell, N., McMenamin, S., Horn, C., Wilms-Floet, A., & Clark, J. (2006). Perception-action coupling in children with and without DCD: Frequency locking between task relevant auditory signals and motor responses in a dual motor task. Child: Care, Health, and Development, 32, 679-692]. In the present study, we examine the same task (clapping in-phase to marching on a platform) under conditions involving the removal of vision and hearing. Eleven children with DCD (mean=7.21, SD=0.52 years), 7 typically developing (TD) children (mean=6.95+/-0.72 years), and 10 adults performed continuous clapping while marching under four conditions: with vision and hearing, without vision, without hearing, and without both. Results showed no significant condition effects for any measure taken. The DCD group was more variable in phasing their claps and footfalls than both the adult group and the TD group. There were also significant group effects for inter-clap interval coefficient of variation and inter-footfall interval coefficient of variation, with the DCD group being the most variable for both measures. Coherence analysis between limb combinations (e.g., left arm-right arm, right arm-left leg) revealed that the adults exhibited significantly greater coherence for each combination than both of the children's groups. The TD group showed significantly greater coherence than the DCD group for every limb combination except foot-foot and left hand-right foot. Measures of approximate entropy indicated that adults differed from children both with and without DCD in the structure of the variability across a trial with adults showing more complexity. Children with DCD are able to accomplish a self-initiated gross-motor coordination task but with increased variability for most but not all measures compared to typically developing children. The availability of visual and/or auditory information does not play a significant role in stabilizing temporal coordination of this task, suggesting that these are not salient sources of information for this particular task.

Transient covert attention does alter appearance: a reply to Schneider (2006)

We recently demonstrated that transient covert attention increases the apparent contrast of a stimulus (Carrasco, Ling, & Read, 2004). Schneider (2006) proposes that the observed increase in apparent contrast is largely due to sensory interactions occurring between the precue a nd stimulus,rather than to attention. Specifically, hereports that cuing effects only occur at contrasts ne ar detection threshold, and that there a re confounding sensoryinteractions between the cue and stimulus at suprathreshold detection contrasts. Our response is twofold. First, we outline the key methodological differences between our original study and Schneider's that are likely to account for the different results, and explain how we had ruled out the sensory interaction explanation of the cue. Second, we directly test the prediction put forth by Schneider. If the effects were due to sensory interactions, reversing the luminance polarity of the precue in our paradigm should lead to differential cuing effects. We replicate one of the experiments of our original study and add a condition in which the cue luminance is either black or white. Our results replicated our previous findings-they showed an increase in apparent contrast to a high-contrast stimulus when it was precued. Moreover, we found that the black cue and the white cue had the same effect, thus ruling out the alternative explanation proposed by Schneider. Transient attention does alter contrast appearance.     

Family Treatment of Child Anxiety: Outcomes,Limitations and Future Directions

Anxiety of childhood is a common and serious condition. The past decade has seen an increase in treatment-focussed research, with recent trials tending to give greater attention to parents in the treatment process. This review examines the efficacy of family-based cognitive behaviour therapy and attempts to delineate some of the factors that might have an impact on its efficacy. The choice and timing of outcome measure, age and gender of the child, level of parental anxiety, severity and type of child anxiety and treatment format and content are scrutinised. The main conclusions are necessarily tentative, but it seems likely that Family Cognitive Behaviour Therapy (FCBT) is superior to no treatment, and, for some outcome measures, also superior to Child Cognitive Behaviour Therapy (CCBT). Where FCBT is successful, the results are consistently maintained at follow-up. It appears that where a parent is anxious, and this is not addressed, outcomes are less good. However, for children of anxious parents, FCBT is probably more effective than CCBT. What is most clear is that large, well-designed studies, examining these factors alone and in combination, are now needed.     

Use of virtual reality distraction to reduce claustrophobia symptoms during a mock magnetic resonance imaging brain scan: a case report.

The present case series with two patients explored whether virtual reality (VR) distraction could reduce claustrophobia symptoms during a mock magnetic resonance imaging (MRI) brain scan. Two patients who met DSM-IV criteria for specific phobia, situational type (i.e., claustrophobia) reported high levels of anxiety during a mock 10-min MRI procedure with no VR, and asked to terminate the scan early. The patients were randomly assigned to receive either VR or music distraction for their second scan attempt. When immersed in an illusory three-dimensional (3D) virtual world named SnowWorld, patient 1 was able to complete a 10-min mock scan with low anxiety and reported an increase in self-efficacy afterwards. Patient 2 received "music only" distraction during her second scan but was still not able to complete a 10-min scan and asked to terminate her second scan early. These results suggest that immersive VR may prove effective at temporarily reducing claustrophobia symptoms during MRI scans and music may prove less effective.     

The gateway hypothesis of rostral prefrontal cortex (area 10) function

Rostral prefrontal cortex (PFC) is a large brain region, and is unusually large in humans. Therefore, it seems likely that it might support functions that are central to cognition. However, until recently, almost nothing was known about what these functions might be. The 'gateway hypothesis' places these abilities at the centre of human mental processing. It maintains that rostral PFC supports mechanisms that enable us to attend, to a novel degree, either to environmental stimuli, or by contrast, to self-generated or maintained representations (i.e. the 'thoughts in our head'). In this way, investigations into the functions of rostral PFC will reveal key new insights into how human and non-human mental abilities differ.
