Influence of weight loss therapy programs in body image self-perception in adults with intellectual disabilities

Some studies suggest that people with intellectual disabilities (ID) might show distortions regarding body image self-perception. The objectives of this study were to investigate whether people with ID could correctly identify their body image and to determine if participating in a weight loss therapy program (WLTP) influenced in any way that perception. For that purpose, an experiment was proposed and all along a weight loss therapy program, a comparison between a body image subjective measure, as the Stunkard scale, and an objective one, as body mass index, was performed. The results obtained showed that individuals with ID (n = 24) perceived in a wrong way their body image before any intervention program (58%). After applying the WLTP for ten weeks, an accentuation in this perception distortion (83%), mostly related with underestimation, was observed with respect to actual body mass index values. The strongest conclusion that can be drawn from this study is that people with ID do not correctly identify their body image. Furthermore, participating in WLTP influences their physical self-concept perception in the way that controlling two variables, as exercise and caloric restriction, causes greater disruption in that perception than controlling only one of them.     

Body image among eating disorder patients with disabilities: A review of published case studies

While individual cases of eating disorder (ED) patients with disabilities have been reported, there has been little synthesis of their experiences of body image and thin idealization. This study reviews 19 published clinical reports of ED patients with sensory, mobility-related, or intellectual disabilities and evaluates the extent to which their experiences align with or challenge current conceptions of body image in ED. ED patients with visual impairment reported a profound disturbance of body image, perceived intersubjectively and through tactile sensations. Reducing dependence in mobility was an important motivation to control body size for ED patients with mobility-related disabilities. ED as a way of coping with and compensating for the psychosocial consequences of disability was a recurrent theme for patients across a range of disabilities. These experiential accounts of ED patients with disabilities broaden current understandings of body image to include touch and kinaesthetic awareness, intersubjective dynamics, and perceptions of normalcy.     

Religious intellectual humility,attitude change,and closeness following religious disagreement

Abstract

This study explored the role of intellectual humility (IH) in promoting attitude change and relationship closeness in the context of religious disagreement. Participants (N = 174) completed a preliminary survey that assessed their attitude on several contentious religious issues (e.g. gay marriage, abortion). Participants who disagreed about a contentious religious issue were then paired and engaged in a 10-min discussion. After the discussion, participants completed a series of questionnaires. The greatest degree of attitude change was seen in pairs with mutually high levels of IH, in which the participant self-reported high levels of IH and also perceived the discussion partner to have high levels of IH. Higher perceptions of the IH levels of the discussion partner predicted higher levels of closeness and trust. We discuss limitations, areas for future research, and practical implications.     

Must we choose our leaders? human rights and political participation in China

The essay begins from Alan Gewirth's influential account of human rights, and specifically with his argument that the human right to political participation can only be fulfilled by competitive, liberal democracy. I show that his argument rests on empirical, rather than conceptual grounds, which opens the possibility that in China, alternative forms of participation may be legitimate or even superior. An examination of the theory and contemporary practice of ‘democratic centralism’ shows that while it does not now adequately support the right to political participation, a reformed version could. I focus in particular on the roles that could be played by consultative institutions, looking both to recent Chinese proposals and to analogues currently existing in Japan. I conclude that a reformed democratic centralism may well be the objective toward which Chinese people should strive.     

Spatial-simultaneous working memory and selective interference in Down syndrome

Several studies have suggested that individuals with Down syndrome (DS) have impairments in some aspects of the visuospatial domain. It has been reported that they are particularly impaired in the spatial-simultaneous working memory (WM) even in advantageous conditions such as when information is grouped to form a configuration. This study aimed to assess the performance of individuals with DS carrying out a spatial-simultaneous WM task in single and dual selective interference conditions in order to better explore the characteristics of their impairment in this area.

Groups of individuals with DS and mentally age-matched typically developing (TD) children were asked to carry out a spatial-simultaneous WM task in a single- and in two dual-task conditions. In the single condition, the participants were required to recall an increasing number of positions of red squares presented simultaneously in a matrix. In the dual-task conditions, together with the spatial-simultaneous WM task, the participants were asked to carry out an articulatory suppression task or a tapping task.

As has already been shown in other studies, individuals with DS were found to be impaired in carrying out a spatial-simultaneous WM task and showed a worse performance with respect to the TD group in both the conditions.

These findings indicate that individuals with DS use the same coding modality as TD children of the same mental age. Just as the TD children, they performed lower in the dual- than in the single-task condition and there was no difference between the verbal and visuospatial conditions.     

Engaging in cultural activities compensates for educational differences in cognitive abilities

ABSTRACT

The goal of the current project was to examine whether engagement in intellectual/cultural activities explains the long-term effects of education on cognitive abilities throughout adulthood, and whether it compensates for educational differences in cognitive abilities throughout adulthood. Participants between 18 and 96 years of age completed a comprehensive questionnaire about intellectual/cultural activities that they participated in and performed a wide variety of cognitive tests. There were no mediation effects of engagement in intellectual/cultural activities on the relationship between education and cognitive functioning. In contrast, engagement in intellectual/cultural activities was found to moderate the relations between education and the level of fluid ability, working memory, speed of processing, and episodic memory. Findings suggest that the risk of cognitive decline in people with less education can be reduced via engagement in intellectual and cultural activities throughout adulthood.     

The emergence of kind-based object individuation in infancy

Four experiments investigated whether 12-month-old infants use perceptual property information in a complex object individuation task, using the violation-of-expectancy looking time method (Xu, 2002; Xu & Carey, 1996). Infants were shown two objects with different properties emerge and return behind an occluder, one at a time. The occluder was then removed, revealing either two objects (expected outcome, if property differences support individuation) or one object (unexpected outcome). In Experiments 1-3, infants failed to use color, size, or a combination of color, size, and pattern differences to establish a representation of two distinct objects behind an occluder. In Experiment 4, infants succeeded in using cross-basic-level-kind shape differences to establish a representation of two objects but failed to do so using within-basic-level-kind shape differences. Control conditions found that the methods were sensitive. Infants succeeded when provided unambiguous spatiotemporal information for two objects, and they encoded the property differences during these experiments. These findings suggest that by 12 months, different properties play different roles in a complex object individuation task. Certain salient shape differences enter into the computation of numerical distinctness of objects before other property differences such as color or size. Since shape differences are often correlated with object kind differences, these results converge with others in the literature that suggest that by the end of the first year of life, infants' representational systems begin to distinguish kinds and properties.     

On the capacity of attention: its estimation and its role in working memory and cognitive aptitudes

Working memory (WM) is the set of mental processes holding limited information in a temporarily accessible state in service of cognition. We provide a theoretical framework to understand the relation between WM and aptitude measures. The WM measures that have yielded high correlations with aptitudes include separate storage-and-processing task components, on the assumption that WM involves both storage and processing. We argue that the critical aspect of successful WM measures is that rehearsal and grouping processes are prevented, allowing a clearer estimate of how many separate chunks of information the focus of attention circumscribes at once. Storage-and-processing tasks correlate with aptitudes, according to this view, largely because the processing task prevents rehearsal and grouping of items to be recalled. In a developmental study, we document that several scope-of-attention measures that do not include a separate processing component, but nevertheless prevent efficient rehearsal or grouping, also correlate well with aptitudes and with storage-and-processing measures. So does digit span in children too young to rehearse.     

注意对拓扑性质和局部几何性质检测的不同影响──进一步的实验证据

实验研究了中央和外周提示信号对辨别朝向的任务（局部几何性质检测）和辨别有或无的任务（拓扑性质检测）的影响。结果表明,对于两种提示信号,在提示有效和提示无效条件下,辨别有或无比辨别朝向具有较短的反应时和较低的错误报告率;辨别朝向的ＲＴ和错误报告率都受提示信号的影响;而对于辨别有或无的任务,只有ＲＴ受提示信号的影响;提示信号对辨别朝向的影响比辨别有或无的影响大。本实验排除了对Ｈａｎ和Ｃｈｅｎ的实验的可能的光通量解释,并为提示信号对不同几何性质检测的不同影响提供了进一步的实验证据。     

Facilitative effects of forgetting from short-term memory on growth of long-term memory in retardates

Competing explanations of the beneficial effect of spacing in retardate discrimination learning were tested. Three-trial multidimensional (“junk”) problems were presented concurrently to educable retardates with MAs over 8 years. The spacing interval spearating Trials 1 and 2 was filled with either zero, four, or eight interpolations, the interpolations being either trials on similar junk problems or repetitions of a single, well-learned dot-pattern discrimination. The principal findings were that: (1) while short-term retention of junk problems (as measured by Trial 2 performance) suffered greater interference from similar junk interpolations than from dot-pattern interpolations, long-term learning (as measured by a delayed Trial 3) was superior following the highly interfering junk problems; and (2) spacing facilitated learning only following highly interfering interpolations. These results are inconsistent with consolidation and rehearsal theories but support the prediction of the Sperber. Greenfield, and House (Journal of Experimental Psychology, 1973, 99) spacing model that forgetting from short-term memory facilitates retardate learning.
