Abstract Childhood obesity is reaching epidemic proportions in the United States today. Children become its victims and often carry obesity-producing habits into adulthood. Much research has been reported on obesity, but little has touched on how family dynamics affect childhood obesity. This article explores the family dynamics of childhood obesity, and presents evidence supporting the need for a family-based treatment model. 相似文献

Two experiments are reported here in which Ss were asked to rate videotapes of a performer reading friendly, neutral and hostile messages in a friendly, neutral or hostile non-verbal style. These messages and non-verbal styles had previously been presented independently to a separate group of Ss jor rating, in order to obtain an estimate of their individual strengths in terms of six rating scales, and thus permit a matching of verbal (messages) and non-verbal (styles) cues in the experiment where both types of cues were presented in combination. The results of both experiments indicate that non-verbal cues had a greater effect on ratings made on 7-point scales, such as hostile-friendly, than verbal cues. The magnitude of this greater effect of non-verbal cues, however, was dependent on the relative strength of non-verbal as opposed to verbal cues. In the first experiment, both types of cues were approximately equal in strength when ruted alone; here non-verbal cues accounted for 12.5 times us much variance us verbal cues, and produced 5.7 times as much shift on the ratitig scales. In the second experiment the verbal cues were much stronger than the non-verbal cues when rated alone. Here the relative effect of non-verbal cues in the second experiment was diminished; the ratio of non-verbal : verbal variance was now 1.67:1. When verbal and non-verbal signals were inconsistent, the performance was rated as insincere, unstable and confusing - which was not found in earlier experiments on the superior-inferior dimension. 相似文献

Three groups of four rats were trained on an auditory-intensity discrimination for 21 days. The SD-SΔ intensity difference for Group I was 10 db; for Group II, 20 db; and for Group III, 30 db. Following the initial discrimination training, the animals were tested for generalization of the bar-press response to seven novel SΔ's which were presented intermingled with the original SD and SΔ values. Conclusions: (1.) The amount of simple discrimination training required to obtain fairly stable differences in SD and SΔ responding is an inverse function of the magnitude of the stimulus difference between SD and SΔ. (2.) Generalization gradients obtained immediately following simple discrimination training exhibit a maximum displaced from SD in a direction also away from SΔ. (3.) Gradients obtained following continued exposure to the multivalued SΔ situation show a fairly stable maximum at the SD value. (4.) Although the gradients tend to fall off systematically on either side of the continuum as distance from SD is increased, they decrease most rapidly on the SΔ limb of the gradient. 相似文献

Executive dysfunction is a characteristic impairment of individuals with Autism Spectrum Disorders (ASD). However whether such deficits are related to autism per se, or to associated intellectual disability is unclear. This paper examines executive functions in a group of children with ASD (N = 54, all IQ?70) in relation to a typically developing control group individually matched on the basis of age, gender, IQ and vocabulary. Significant impairments in the inhibition of prepotent responses (Stroop, Junior Hayling Test) and planning (Tower of London) were reported for children with ASD, with preserved performance for mental flexibility (Wisconsin Card Sorting Task) and generativity (Verbal Fluency). Atypical age-related patterns of performance were reported on tasks tapping response inhibition and self-monitoring for children with ASD compared to controls. The disparity between these and previous research findings are discussed. A multidimensional notion of executive functions is proposed, with difficulties in planning, the inhibition of prepotent responses and self-monitoring reflecting characteristic features of ASD that are independent of IQ and verbal ability, and relatively stable across the childhood years. 相似文献

The present study investigated whether auditory temporal processing deficits are related to the presence and/or the severity of periventricular brain injury and the reading difficulties experienced by extremely low birthweight (ELBW: birthweight <1000 g) children. Results indicate that ELBW children with mild or severe brain lesions obtained significantly lower scores on a test requiring auditory temporal order judgments than ELBW children without periventricular brain injury or children who were full-term. Structural equation modeling indicated that a model in which auditory temporal processing deficits predicted speech sound discrimination and phonological processing ability provided a better fit for the data than did a second model, which hypothesized that auditory temporal processing deficits are associated with poor reading abilities through a working memory deficit. These findings suggest that an impairment in auditory temporal processing may contribute to the reading difficulties experienced by ELBW children. 相似文献

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching. 相似文献

The present study investigated verbal and spatial working memory (WM) functioning in individuals with the neuro-developmental disorder Williams syndrome (WS) using WM component tasks. While there is strong evidence of WM impairments in WS, previous research has focused on short-term memory and has neglected assessment of executive components of WM. There is a particular lack of consensus concerning the profile of verbal WM functioning in WS. Here, WS participants were compared to typically developing participants matched for (1) verbal ability and (2) spatial ability (N = 14 in each of the 3 groups). Individuals with WS were impaired on verbal WM tasks, both those involving short-term maintenance of information and executive manipulation, in comparison to verbal-matched controls. Surprisingly, individuals with WS were not impaired on a spatial task assessing short-term maintenance of information in memory (remembering spatial locations) compared to spatial-matched controls. They were, however, impaired on a spatial executive WM task requiring the manipulation of spatial information in memory. The present study suggests that individuals with WS show WM impairments that extend to both verbal and spatial domains, although spatial deficits are selective to executive aspects of WM function. 相似文献

Latinos comprise a diverse ethnic group in the United States, yet central concepts describing Latinos persist. The purpose
of this study was to assess the degree to which Latinos agree with the statements found in the marriage and family therapy
(MFT) literature used to describe Latinos and Latino families, as well as their help-seeking attitudes and experiences. Research
questions were derived from five constructs used to describe Latinos: familism, personalism, sense of hierarchy, spiritualism, and fatalism (Ho in Family therapy with ethnic minorities. Sage, Newbury, CA, 1987; Ho et al. in Family therapy with ethnic minorities, (2nd ed.). Sage, Thousand Oaks, CA, 2004). Overall, participants agreed with most of the statements pertaining to familism and personalism. However, mixed results were found for the constructs related to sense of hierarchy, spiritualism, and fatalism, as well as for participants’ help-seeking attitudes and behaviors. Latinos in this sample sought mental health professionals.
However, MFTs were not sought as frequently as psychiatrists, psychologists, and clergy. 相似文献

Worry is thought to involve a strategy of cognitive avoidance, in which internal verbalization acts to suppress threatening emotional imagery. This study tested the hypothesis that worry-prone individuals would exhibit patterns of between-hemisphere communication that reflect cognitive avoidance. Specifically, the hypothesis predicted slower transfer of threatening images from the left to the right hemisphere among worriers. Event-related potential (ERP) measures of interhemispheric transfer time supported this prediction. Left-to-right hemisphere transfer times for angry faces were relatively slower for individuals scoring high in self-reported worry compared with those scoring low, whereas transfer of happy and neutral faces did not differ between groups. These results suggest that altered interhemispheric communication may constitute one mechanism of cognitive avoidance in worry. 相似文献
