In typically developing children, researchers have found that anxiety disorders are associated with poorer intellectual abilities
(Davis et al. Journal of Psychopathology and Behavioral Assessment 30:43–51, 2008). The aim of the current study was to examine the impact anxiety symptoms had on the developmental quotients of toddlers.
A total of 170 toddlers ranging in age from 17 to 37 months were selected for inclusion in this study, all of whom were at
risk for or had a developmental delay. Two factors indicative of behavioral symptoms of anxiety from the Baby and Infant Screen for Children with aUtIsm Traits-Part2 were utilized as the independent variables and the total developmental quotient from the Battelle Developmental Inventory, 2nd Edition was utilized for the dependent variable. Examination of results revealed that atypically developing toddlers with symptoms
of anxiety had significantly lower developmental quotients when compared to toddlers without any anxiety symptoms. A discussion
of the implications and limitations of this study are included. 相似文献

Conscious visual perception of the constantly changing environment is one of the brain's most critical functions. In virtually every moment of every daily activity, the visual system is confronted with the task of accurately representing and interpreting scenes that change rapidly over time. Adults can judge the identity and order of changing images presented at a rate of up to 10 Hz (~50 ms per image); this limit reflects a finite temporal resolution of attention. In the research reported here, although 6- to 15-month-old infants could detect the presence of rapid flicker without difficulty, their ability to segment individual alternating states within the flicker was severely limited: Fifteen-month-old infants had a temporal resolution of attention approximately one order of magnitude lower than that of adults (~1 Hz). Coarse temporal resolution constrains how infants perceive and utilize dynamic visual information and may play a role in the visual processing deficits found in individuals with neurodevelopmental disorders. 相似文献

Current energy debates are often framed in terms of the extent to which energy sources may mitigate global climate change
(GCC) and facilitate energy independence (EI). However, little is understood about whether and how attitudes towards GCC and
EI influence attitudes toward energy sources. Our study included 277 undergraduate students enrolled in introductory psychology
classes at a large, Southeastern university. As hypothesized, results from ordinal and binary logistic regression analyses
revealed that the likelihood participants would support the use of solar, wind, coal or nuclear energy decreased as a function
of their belief that an energy source contributed to GCC. The belief that an energy source contributed to EI increased participants’
likelihood of support. Results suggest that beliefs about GCC and EI are important to determining support for energy sources
and will likely contribute to effective marketing strategies and efforts to implement more environmentally-sustainable behavior
and energy policy. 相似文献

Williams syndrome (WS) is a genetic disorder associated with severe visuospatial deficits, relatively strong language skills, heightened social interest, and increased attention to faces. On the basis of the visuospatial deficits, this disorder has been characterized primarily as a deficit of the dorsal stream, the occipitoparietal brain regions that subserve visuospatial processing. However, some evidence indicates that this disorder may also affect the development of the ventral stream, the occipitotemporal cortical regions that subserve face and object recognition. The present studies examined ventral stream function in WS, with the hypothesis that faces would produce a relatively more mature pattern of ventral occipitotemporal activation, relative to other objects that are also represented across these visual areas. Using functional magnetic imaging, we compared activation patterns during viewing of human faces, cat faces, houses and shoes in individuals with WS (age 14-27), typically developing 6-9-year-olds (matched approximately on mental age), and typically developing 14-26-year-olds (matched on chronological age). Typically developing individuals exhibited changes in the pattern of activation over age, consistent with previous reports. The ventral stream topography of individuals with WS differed from both control groups, however, reflecting the same level of activation to face stimuli as chronological age matches, but less activation to house stimuli than either mental age or chronological age matches. We discuss the possible causes of this unusual topography and implications for understanding the behavioral profile of people with WS. 相似文献

The purpose of this study was to assess primary care physicians’ awareness, experience, opinions and preparedness to answer
patients’ questions regarding direct-to-consumer (DTC) genetic testing. An anonymous survey was mailed to 2,402 family and
internal medicine providers in North Carolina. Of the 382 respondents, 38.7% (n = 148) were aware of and 15% (n = 59) felt prepared to answer questions about DTC genetic tests. Respondents aged 50 or older were more likely to be aware
of DTC genetic testing than those less than 40 years old (OR = 2.42). Male providers were more likely to feel prepared to answer questions than female providers (OR = 2.65). Among respondents who reportedly were aware, family practitioners were more likely than internists (OR = 3.30) to think DTC testing was clinically useful, and 18.9% had patients ask questions or bring in test results. The small
percent of physicians who were aware of DTC genetic testing or felt prepared to answer questions about it suggests that education
of providers will be necessary if testing becomes more widespread. 相似文献

Autism spectrum disorders (ASDs) are life-long developmental disorders characterized by impairments in the development of reciprocal social and communication skills, abnormal language development, and a restricted repertoire of behaviors and interests. While it has been known for some time that children with ASD can evince elevated rates of anxiety symptoms, little research has been conducted on whether deficits in communication skills affect the range of anxiety symptoms in infants and toddlers with ASD. This study represents a first attempt to determine whether deficits in communication skills have an effect on the expression of anxiety in infants and toddlers with autistic disorder and pervasive developmental disorder-not otherwise specified. Seven hundred thirty-five infants were evaluated with respect to the nature and extent of anxiety symptoms and developmental functioning. Both receptive and expressive communication skills appeared to play a significant role in the manifestation of anxiety symptoms. 相似文献

This research revealed the joint impact of personality traits, social axioms, role relationships and the privacy of social situations on the enactment of three types of modesty, namely, avoiding attention, self‐effacement, and enhancement of others, among Hong Kong Chinese teenage females. The modest personality trait was found to relate positively to these modest behaviours. An individual's belief in reward for application significantly predicted self‐effacement, and the belief in social cynicism significantly predicted avoiding attention and enhancement of others. Contextual variables as measured by the role relationships and the privacy of the social setting also significantly affected the levels of these modest behaviours. 相似文献
