Neurocognitive dysfunction in children with sleep disorders

It is well known that adults with sleep disturbances frequently exhibit a wide range of neurocognitive decrements, and that these deficits are potentially reversible with effective treatment. However, the consequences of respiratory sleep disturbances on neurocognitive function in children have only recently been evaluated, and suggest a strong causal association between the episodic hypoxia and sleep fragmentation that characterize the disease and the emergence of reduced memory, attention and intelligence as well as a link to problematic and hyperactive behaviours and mood disturbances. This article takes a critical look at the current literature on these issues, reviews the major findings and discusses such findings in conjunction with those derived from pertinent animal models.

Prospective and retrospective time perception are related to mental time travel: Evidence from Alzheimer’s disease

Unlike prospective time perception paradigms, in which participants are aware that they have to estimate forthcoming time, little is known about retrospective time perception in normal aging and Alzheimer’s disease (AD). Our paper addresses this shortcoming by comparing prospective and retrospective time estimation in younger adults, older adults, and AD patients. In four prospective tasks (lasting 30 s, 60 s, 90 s, or 120 s) participants were asked to read a series of numbers and to provide a verbal estimation of the reading time. In four other retrospective tasks, they were not informed about time judgment until they were asked to provide a verbal estimation of four elapsed time intervals (lasting 30 s, 60 s, 90 s, or 120 s). AD participants gave shorter verbal time estimations than older adults and younger participants did, suggesting that time is perceived to pass quickly in these patients. For all participants, the duration of the retrospective tasks was underestimated as compared to the prospective tasks and both estimations were shorter than the real time interval. Prospective time estimation was further correlated with mental time travel, as measured with the Remember/Know paradigm. Mental time travel was even higher correlated with retrospective time estimation. Our findings shed light on the relationship between time perception and the ability to mentally project oneself into time, two skills contributing to human memory functioning. Finally, time perception deficits, as observed in AD patients, can be interpreted in terms of dramatic changes occurring in frontal lobes and hippocampus.     

Children and Spirituality in the Context of a Traditional Festival: Halloween

This paper examines some of the contemporary cultural practices associated with the traditional festival of Halloween as it is celebrated by children in Britain and the United States. Using ethnographic evidence from a variety of sources, the authors seek to explore the range of activities which constitute the modern Halloween, particularly as it is mediated to children through the forms of consumer culture. The paper analyses the changing social, historical and religious patterns which have displaced the celebration of Halloween onto children, and offers an account of them which points to the persistence of a coherent spirituality—what the authors term a ‘spirituality of boundaries‘—to be found in the symbolism of the festival and its interaction with the lives and representation of children.     

A Latina Luthercostal Invitation Into an Ecclesial Estuary

Drawing from ethnographic and meta‐ethnographic research, this article analyzes the hermeneutic, and resulting ecclesiology, of Latina Luthercostal women in Latino/a Lutheran congregations in New York and Philadelphia. Preliminary findings suggest that Latina Luthercostal hermeneutics mirror Martin Luther's own hermeneutical approach. This particular hermeneutical lens invites the church into an ecclesial estuary where seemingly opposed traditions meet and are drawn by the Holy Spirit into a messy, meaningful, and necessary experience of death and resurrection for the purposes of transformation and renewal.     

Self-regulation evaluation of therapeutic yoga and walking for patients with irritable bowel syndrome: a pilot study

With limited efficacy of medications for symptom relief, non-medication treatments may play an important role in the treatment of irritable bowel syndrome (IBS), the most common functional gastrointestinal (GI) disorder. This study aimed to evaluate the efficacy of two self-regulation strategies for symptom relief and mood management in IBS patients. Thirty-five adult participants meeting ROME III criteria for IBS were enrolled, 27 of the 35 participants (77%) completed treatment and pre- and post-treatment visits (89% women, 11% men; M (SD) age = 36 (13)), and 20 of the 27 (74%) completed a 6-month follow-up. Participants were randomly assigned to 16 biweekly group sessions of Iyengar yoga or a walking program. Results indicated a significant group by time interaction on negative affect with the walking treatment showing improvement from pre- to post-treatment when compared to yoga (p < .05). There was no significant group by time effect on IBS severity. Exploratory analyses of secondary outcomes examined change separately for each treatment condition. From pre- to post-treatment, yoga showed significant decreases in IBS severity measures (p < .05), visceral sensitivity (p < .05), and severity of somatic symptoms (p < .05). Walking showed significant decreases in overall GI symptoms (p < .05), negative affect (p < .05), and state anxiety (p < .05). At 6-month follow-up, overall GI symptoms for walking continued to significantly decline, while for yoga, GI symptoms rebounded toward baseline levels (p < .05). When asked about self-regulated home practice at 6 months, significantly more participants in walking than in yoga practiced at least weekly (p < .05). In sum, results suggest that yoga and walking as movement-based self-regulatory behavioral treatments have some differential effects but are both beneficial for IBS patients, though maintenance of a self-regulated walking program may be more feasible and therefore more effective long term.     

Destination memory and cognitive theory of mind in normal ageing

Destination memory is the ability to remember the destination to which a piece of information has been addressed (e.g., “Did I tell you about the promotion?”). This ability is found to be impaired in normal ageing. Our work aimed to link this deterioration to the decline in theory of mind. Forty younger adults (M age = 23.13 years, SD = 4.00) and 36 older adults (M age = 69.53 years, SD = 8.93) performed a destination memory task. They also performed the False-belief test addressing cognitive theory of mind and the Reading the mind in the eyes test addressing affective theory of mind. Results showed significant deterioration in destination memory, cognitive theory of mind and affective theory of mind in the older adults. The older adults’ performance on destination memory was significantly correlated with and predicted by their performance on cognitive theory of mind. Difficulties in the ability to interpret and predict others’ mental states are related to destination memory decline in older adults.     

Is anaphoric reference cooperative?

Two experiments investigated whether the choice of anaphoric expression is affected by the presence of an addressee. Following a context sentence and visual scene, participants described a target scene that required anaphoric reference. They described the scene either to an addressee (Experiment 1) or without an addressee (Experiment 2). When an addressee was present in the task, participants used more pronouns and fewer repeated noun phrases when the referent was the grammatical subject in the context sentence than when it was the grammatical object and they used more pronouns when there was no competitor than when there was. They used fewer pronouns and more repeated noun phrases when a visual competitor was present in the scene than when there was no visual competitor. In the absence of an addressee, linguistic context effects were the same as those when an addressee was present, but the visual effect of the competitor disappeared. We conclude that visual salience effects are due to adjustments that speakers make when they produce reference for an addressee, whereas linguistic salience effects appear whether or not speakers have addressees.
