A revolution in the science of emotion has emerged recent decades, with potential to create a paradigm shift decision theories. The research reveals that emotions constitute potent, pervasive, predictable, sometimes harmful and ...Read More
Objectives. This study examined the hypothesis that domains of neurobehavioral function would be selectively affected by sleep-disordered breathing (SDB). Therefore, we assessed potential relationships between objectively measured sleep disturbances and in children with reported symptoms attention-deficit/hyperactivity disorder (ADHD) also determined incidence snoring other problems 5- to 7-year-old local community parental passive smoking. Methods. Parents public schools were surveyed about...
Objective. Current guidelines for the treatment of children with obstructive sleep apnea (OSA) suggest that primary snoring (PS) in is benign. However, PS has not been well evaluated, and it unknown whether associated serious morbidity. This study investigated neurobehavioral deficits children. Methods. Parents 5- to 7-year-old public schools were surveyed about their child’s sleeping habits. Children a history nonsnoring invited overnight polysomnographic assessment battery tests. Only who...
Summary The effects of sleep‐disordered breathing (SDB) on neurobehavioral function were examined in two matched groups children from the general population. Thirty‐five with polysomnographically confirmed SDB for ethnicity, age, gender, maternal educational attainment, and smoking, to healthy no evidence SDB. Children had significantly lower mean scores Differential Ability Scales General Conceptual (similar IQ) Non‐verbal Cluster. On neuropsychology assessment battery (NEPSY), scored than...
The Williams-Beuren syndrome (WBS) locus, at 7q11.23, is prone to recurrent chromosomal rearrangements, including the microdeletion that causes WBS, a multisystem condition with characteristic cardiovascular, cognitive, and behavioral features. It hypothesized reciprocal duplications of WBS interval should also occur, here we present such case description. most striking phenotype was severe delay in expressive speech, contrast normal articulation fluent language observed persons WBS. Our...
Abstract The prevalence of a range DSM‐IV psychiatric disorders in sample 119 4–16‐year‐old children with Williams syndrome (WS) was assessed using structured diagnostic interview their parents. Most (80.7%) met criteria for at least one diagnosis. most prevalent diagnoses were Attention Deficit/Hyperactivity Disorder (ADHD; 64.7%) and Specific Phobia (53.8%). There significant shift Predominant Type ADHD as function CA, from Combined the youngest group (ages 4–6 years) to Inattentive oldest...
Toddlers' acquisition of the Novel Name-Nameless Category (N3C) principle was examined to investigate developmental lexical principles framework and applicability specificity hypothesis relations involving principles. In Study 1, we assessed ability 32 children between ages 16 20 months use N3C (operationally defined as fast map). As predicted, only some could map. This finding provided evidence for a crucial tenet framework: Some are not available at start language acquisition. Children who...
Six experiments were conducted on the effects of expertise basic-level categorization. Individuals with varying levels knowledge about songbirds generated lists attributes, named objects, identified and discriminated among object silhouettes, verified category membership at 4 hierarchical levels, visually primed either by species-specific, related, or unrelated birdsong. Results indicated that original basic level never lost its privileged status. Expertise increased access to categorical...
MERVIS, CAROLYN B., and CRIsAFI, MARIA A. Order of Acquisition Subordinate-, Basic-, Superordinate-Level Categories. CHILD DEVELOPMENT, 1982, 53, 258-266. The present research was concerned with the order acquisition ability to categorize at different hierarchical levels. first experiment designed test hypothesis that categorization is acquired in following order: basic, superordinate, subordinate. Children aged 2-6, 4, 5-6 were asked indicate which, 2 nonsense stimuli, same kind thing as a...
Although previous research and clinical observation have indicated that individuals with Williams syndrome a distinctive personality, an empirically derived personality profile has not been developed. The objective of the current investigation was to develop is descriptive children syndrome. Participants were 23 8- 10-year-old 20 developmental disabilities other etiologies. Participant groups had equivalent intellectual abilities. Parents completed measures childhood temperament (Children's...
