Hierarchical forms processing in adults and children

Two experiments examined child and adult processing of hierarchical stimuli composed of geometric forms. Adults (ages 18-23 years) and children (ages 7-10 years) performed a forced-choice task gauging similarity between visual stimuli consisting of large geometric objects (global level) composed of small geometric objects (local level). The stimuli spatial arrangement was manipulated to assess child and adult reaction times and predisposition toward local or global form categorization under two distinct trial conditions, with varied density of the local forms comprising the global forms. In Experiment 1, children and adults were presented with common, simple geometric shape hierarchical forms composed of ovals and rectangles. In Experiment 2, adults were presented with hierarchical forms composed of the simple geometric shapes, ovals and rectangles, and additional novel complex geometric shapes, “posts” and “arches.” Results show a clear increase of global processing bias across the age ranges of the individuals in the study, with children at 10 years performing similarly to adults on the simple stimuli. In addition, adults presented with the novel complex geometric shapes showed a significant reduction in global processing bias, indicating that form novelty and complexity lead to additional attention to local features in categorization tasks.     

The global non-entropic arrow of time: from global geometrical asymmetry to local energy flow

Since the nineteenth century, the problem of the arrow of time has been traditionally analyzed in terms of entropy by relating the direction past-to-future to the gradient of the entropy function of the universe. In this paper, we reject this traditional perspective and argue for a global and non-entropic approach to the problem, according to which the arrow of time can be defined in terms of the geometrical properties of spacetime. In particular, we show how the global non-entropic arrow can be transferred to the local level, where it takes the form of a non-spacelike local energy flow that provides the criterion for breaking the symmetry resulting from time-reversal invariant local laws.     

TYPES OF PRAYER,HEART RATE VARIABILITY,AND INNATE HEALING

Spiritual practices such as prayer have been shown to improve health and quality of life for those facing chronic or terminal illness. The early Christian healing tradition distinguished between types of prayer and their role in healing, placing great emphasis on the healing power of more integrated relational forms of prayer such as prayers of gratitude and contemplative prayer. Because autonomic tone is impaired in most disease states, autonomic homeostasis may provide insight into the healing effects of prayer. I report on observations in five volunteers engaging in five types of prayer. Using heart rate variability as a measure of autonomic tone and adaptability, I review the potential correlation of type of prayer with autonomic rebalance as measured specifically by psychophysiological coherence ratios. The five types—supplication, devotion, intercession, gratefulness, and contemplative prayer—elicited varying degrees of improvements in heart rate variability and corresponding psychophysiological coherence. These observations suggest a correlation of innate healing to prayer type that is consistent with teachings from the Christian healing tradition and with modern research. Further research is warranted to verify these hypotheses.     

The Impossibility of Local Skepticism

According to global skepticism, we know nothing. According to local skepticism, we know nothing in some particular area or domain of discourse. Unlike their global counterparts, local skeptics think they can contain our invincible ignorance within limited bounds. I argue that they are mistaken. Local skepticism, particularly the kinds that most often get defended, cannot stay local: if there are domains whose truths we cannot know, then there must be claims outside those domains that we cannot know even if they are true. My argument focuses on one popular form of local skepticism, ethical skepticism, but I believe that the argument generalizes to cover other forms as well.

Story Recall and Narrative Coherence of High-Functioning Children with Autism Spectrum Disorders

Previous research has found few quantitative differences between children with high-functioning autism spectrum disorders (ASDs) and well-matched controls in the length, complexity, and structure of their narratives. Researchers have noted, however, that narratives of children with ASDs have an unusual and idiosyncratic nature. This study provides an analysis of narratives in 17 children with high-functioning ASDs and 17 typically developing children matched on age, gender, language abilities, and cognitive abilities. We examined story recall and narrative coherence. The study revealed no group differences in story length or syntactic complexity. Children with ASDs also did not differ from controls in their use of the gist of a story to aid recall, or in their sensitivity to the importance of story events. Children with ASDs did, however, produce narratives that were significantly less coherent than the narratives of controls. Children with ASDs appeared less likely to use the gist of the story to organize their narratives coherently. These findings are discussed with regard to their relationship to other cognitive and linguistic difficulties of children with ASDs.     

Beyond Defiance: An Augmented Investment Perspective on Creativity

An investment perspective on creativity, proposed 30 years ago, no longer seems adequate, nor do various revisions of the model made since then. The world, or at least the way many people experience it, has changed and so have the challenges for creativity. In particular, creativity is being used to increasingly greater effect in negative ways and in ways that lack integrity with respect both to internal coherence and external correspondence to the world. To understand creativity and adequately teach it, people need to take into account its positivity and its integrity with respect to internal coherence and external correspondence.     

刺激结构对视觉定位的影响

本实验采用多点定位作业,结合部分报告法,研究视觉刺激的整体结构对定位成绩的影响。所呈现的刺激为1、2、3或4个颜色点。其中2、3、4点刺激分别是直线、正三角形和正方形。结果发现,当呈现时间较长时,1点和2、3、4点的定位误差无显著差异。但是1点的定位反应时却显著少于2、3、4点。这提示出现视觉定位的结构效应。而当呈现时间较短时,却没有这种结构效应。实验还发现,这种结构效应并不因刺激结构的不同而有区别。     

Development of sense of coherence during two group interventions

Kähönen, K., Näätänen, P., Tolvanen, A. & Salmela‐Aro, K. (2012). Development of sense of coherence during two group interventions. Scandinavian Journal of Psychology 53, 523–527. Burnout is a serious occupational hazard. This study investigated the possibility to develop an effective salutogenic group intervention among employees suffering from severe burnout symptoms. Participants consisted of employees aged 31 to 59 years working in different public service occupations, such as police officers, tax officers, (and other public service officers), and assigned to three different groups: analytic (N = 25), psychodramatic (N = 24) and controls (N = 28). The intervention comprised 16 separate days over a nine‐month period. Changes in sense of coherence (SOC) were measured four times with the 13‐item Orientation to Life Questionnaire during the intervention and at six‐month follow‐up, and analyzed by general linear model (GLM) and using Cohen’s d to estimate effect sizes. Change in SOC between the three groups was statistically significant (F(4,148) = 2.65, p = 0.036). The psychodrama group showed a higher increase in SOC than the analytic group during the intervention, while the improvement in the analytic group was significant during the six‐month follow‐up. Total effect size from baseline to follow‐up was in the analytic group 0.71, in the psychodrama group 0.47, and in the control group from baseline to end of intervention 0.09. The results show that it is possible to improve SOC by group intervention in the occupational healthcare context. The dialogue‐based analytic method and action‐based psychodramatic method differ in their specific effects.     

Sense of coherence as a protective factor for psychological distress among gay men: a prospective cohort study

Gay men face a greater risk of psychological distress than heterosexual men, yet research on protective factors among gay men has been limited. This prospective cohort study investigated whether a sense of coherence (SOC), as a form of coping, helps to protect against psychological distress among middle-aged and older gay men. A nationwide online survey was conducted among a baseline sample of 1135 Australian gay-identified men aged 40 years and older, with a follow-up survey 12 months later. SOC was measured using the 13-item SOC Scale. Psychological distress was measured using the K10 Psychological Distress Scale. Hierarchical regressions were conducted, with analyses controlling for several potential risk factors for distress. Over half of participants had moderate or high psychological distress. However, baseline distress was significantly lower among those with stronger baseline SOC. In addition, baseline SOC significantly predicted distress 12 months later. This predictive effect of SOC was independent of baseline distress levels and occurred despite a strong correlation between baseline and follow-up distress. With SOC appearing to be a protective factor, strategies among middle-aged and older gay men that strengthen SOC may assist in the prevention and treatment of anxiety and other psychological distress in this vulnerable population.
