Effects of a checklist on self-assessment of blood glucose level by a memory-impaired woman with diabetes mellitus

This study evaluated effects of a checklist on the accuracy of self-assessment of blood glucose level by a diabetic woman with memory impairments caused by viral encephalitis. The checklist consisted of 54 steps for operating an electronic glucometer, which the subject performed in sequence and checked off when completed. Following introduction of the checklist, the percentage of steps completed correctly increased in simulated and actual blood glucose tests and yielded clinically useful information.     

Cognitive contributions to theory of mind ability in children with a traumatic head injury

The objective of the current study is to examine the contribution of intellectual abilities, executive functions (EF), and facial emotion recognition to difficulties in Theory of Mind (ToM) abilities in children with a traumatic head injury. Israeli children with a traumatic head injury were compared with their non-injured counterparts. Each group included 18 children (12 males) ages 7–13. Measurements included reading the mind in the eyes, facial emotion recognition, reasoning the other’s characteristics based on motive and outcome, Raven’s Coloured Progressive Matrices, similarities and digit span (Wechsler Intelligence Scale for Children – Revised 95 subscales), verbal fluency, and the Behaviour Rating Inventory of Executive Functions. Non-injured children performed significantly better on ToM, abstract reasoning, and EF measures compared with children with a traumatic head injury. However, differences in ToM abilities between the groups were no longer significant after controlling for abstract reasoning, working memory, verbal fluency, or facial emotion recognition. Impaired ToM recognition and reasoning abilities after a head injury may result from other cognitive impairments. In children with mild and moderate head injury, poorer performance on ToM tasks may reflect poorer abstract reasoning, a general tendency to concretize stimuli, working memory and verbal fluency deficits, and difficulties in facial emotion recognition, rather than deficits in the ability to understand the other’s thoughts and emotions. ToM impairments may be secondary to a range of cognitive deficits in determining social outcomes in this population.     

Prospective memory and frontal lobe function

The study sought to examine the role of frontal lobe functioning in focal prospective memory (PM) performance and its relation to PM deficit in older adults. PM and working memory (WM) differences were studied in younger aged (n = 21), older aged (n = 20), and frontal injury (n = 14) groups. An event-based focal PM task was employed and three measures of WM were administered. The younger aged group differed from the other two groups in showing significantly higher scores on PM and on one of the WM measures, but there were no differences at a statistically significant level between the older aged group and the frontal injury groups on any of the memory measures. There were, however, some differences in correlations with a WM measure between groups. It is concluded that there are similarities and differences in the deficits in PM between older adults and patients with frontal lobe injury on focal as well as nonfocal PM tasks.     

Spatial-temporal analysis of pedestrian injury severity with geographically and temporally weighted regression model in Hong Kong

This study intended to (1) investigate the pedestrian injury severity involved in traffic crashes; and (2) address the spatial and temporal heterogeneity simultaneously. To achieve the objectives, geographically and temporally weighted regression (GTWR) model was proposed to deal with both spatial and temporal heterogeneity simultaneously. The pedestrian crash data of Hong Kong metropolitan area from 2008 to 2012 were collected, involving 1652 pedestrian-related injury samples. By comparing GTWR model and standard geographically weighted regression (GWR) model and temporally weighted regression (TWR) model, the proposed GTWR model showed potential benefits in modeling both spatial and temporal non-stationarity simultaneously in terms of goodness-of-fit and F statistics. Results revealed that number of vehicles, number of pedestrian-related casualties, speed limit, vehicle movement and injury location have significant influence on pedestrian injury severity in different areas. The conclusions are reached that GRWR model can address the relationship between pedestrian injury severities and influencing factors, as well as accommodating spatial and temporal heterogeneity simultaneously. The findings provide useful insights for practitioners and policy makers to improve pedestrian safety.     

Reciprocal relations between autonomous motivation from self-determination theory and social cognition constructs from the theory of planned behavior: A cross-lagged panel design in sport injury prevention

ObjectivesThe present study examined reciprocal relations between autonomous motivation from self-determination theory (SDT) and constructs from the theory of planned behavior (TPB) in a sport injury context.MethodsThe study adopted a three-wave longitudinal cross-lagged panel design. Physical education students in China (N = 4414; M_age = 14.42, SD = 1.75) completed self-report measures of autonomous motivation, attitude, subjective norm, and perceived behavioral control with respect to sport injury prevention at baseline (T1) and at two follow-up occasions one (T2) and three (T3) months later. Proposed reciprocal relations between autonomous motivation and the TPB constructs controlling for construct stability over time were tested using structural equation modeling.ResultsThree cross-lagged SEMs for effects of constructs measured at T1 on constructs measured at T2 and T3, and effects of constructs measured at T2 on constructs measured at T3 met goodness-of-fit criteria (CFI > 0.95, TLI > 0.94, RMSEA = 0.03, SRMR = 0.05) with consistent patterns of effects. Across the three models, autonomous motivation predicted the prospectively-measured TPB constructs with small-to-medium effect sizes (β range = 0.17 to 0.32, ps < .001), but associations between the TPB variables and prospectively-measured autonomous motivation were markedly smaller in size (β range = 0.01 to 0.18, ps range = .001 to .892).ConclusionsFindings provide initial support for the temporal ordering of the constructs in the integrated model of SDT and TPB in a sport injury context. Autonomous motivation from SDT is likely to be an antecedent of the constructs from the TPB.     

Injury characteristics across functional classes of self-injurious behavior

Self-injurious behavior (SIB) is inherently problematic because it can lead to injuries, including those that are quite severe and may result in loss of function or permanent disfigurement. The current study replicated and extended Rooker et al. (2018) by classifying the physical characteristics of injuries across groups of individuals with automatically maintained SIB (ASIB Subtypes 2 and 3) and socially maintained SIB. Individuals with Subtype 2 ASIB had the most frequent and severe injuries. Further, an inverse relation was found between the level of differentiation in the functional analysis and the number of injuries across groups. Studying the response products of SIB (the injuries) documents the risks associated with SIB, justifies the need for research and the intensive intervention, and advances knowledge of SIB. Additional research is needed to replicate these findings, and determine the variables that produce different characteristics of injury secondary to SIB.     

心理学视角下的道德损伤

道德损伤是指个体实施、未能阻止、目睹或听闻违背自身深层的道德信念和期望的行为,对心理、生理、精神、行为和社会的持久影响。道德损伤作为一个跨学科概念,自2009年Litz从心理学角度对其重新做出界定以来,在心理学、伦理学、精神病学、社会学等领域引起了广泛关注。目前研究者已经编制出多个多维度量表来对道德损伤的事件或症状进行测量,运用认知行为疗法、认知加工疗法和针对道德损伤研发的适当暴露疗法等措施来进行干预。未来的研究可以继续深入探究道德损伤的发生发展机制,确立道德损伤的诊断标准,推广道德损伤的适用范围,丰富道德损伤的内涵,从而拓展道德损伤研究的广度和深度。

Post‐traumatic functional recovery and reorganization in animal models: A theoretical and methodological challenge

Studies addressing cerebral functional localization face methodological and theoretical problems. Lesion experiments expect that when a functionally specialized structure is missing, its function can be deduced from the resulting impairments. Mostly, however, initial impairments are partially or fully eliminated through functional recovery. Apparently, such a recovery contradicts the notion of functional localization. In order to understand the mechanisms of recovery, improved methodology and a new theoretical framework are required. Insights into the mechanisms of recovery can be achieved by using “challenge” techniques, where functionally recovered individuals are exposed to organic and behavioral challenges, e.g. pharmacological manipulations or additional lesions, as well as modified test situations. Using such methods, a number of principles of functional recovery have emerged. We evaluate some of the available theories of post‐traumatic recovery against these principles and find that none of them can account for the principles. Finally, we present a new conceptual framework – the Reorganization of Elementary Functions (REF) model. This model reconceptualizes the term “function”, suggests mechanisms of post‐traumatic reorganizations, and resolves the contradiction between localization and functional recovery.
