Family resemblances: Studies in the internal structure of categories
Abstract Six experiments explored the hypothesis that the members of categories which are considered most prototypical are those with most attributes in common with other members of the category andExpand
Basic objects in natural categories
Abstract Categorizations which humans make of the concrete world are not arbitrary but highly determined. In taxonomies of concrete objects, there is one level of abstraction at which the most basicExpand
Categorization of Natural Objects
ions and general knowledge more extensive than that of individual categories are required in any account of categorization. For example, Pittenger & Shaw (1975, Pittenger et al 1979) argue thatExpand
Acquisition of the novel name--nameless category (N3C) principle.
Toddlers' acquisition of the Novel Name-Nameless Category (N3C) principle was examined to investigate the developmental lexical principles framework and the applicability of the specificityExpand
The Williams Syndrome Cognitive Profile
A Williams Syndrome Cognitive Profile (WSCP) is outlined that operationalizes the cognitive characteristics of the syndrome using measures of absolute and relative performance on subtests of the Differential Abilities Scales (Elliot, 1990a). Expand
Neural Basis of Genetically Determined Visuospatial Construction Deficit in Williams Syndrome
These observations confirm a longstanding hypothesis about dorsal stream dysfunction in Williams syndrome, demonstrate effects of a localized abnormality on visual information processing in humans, and define a systems-level phenotype for mapping genetic determinants of visuoconstructive function. Expand
Neural correlates of genetically abnormal social cognition in Williams syndrome
Functional neuroimaging found reduced amygdala activation in individuals with WBS for threatening faces but increased activation for threatening scenes, relative to matched normal controls, suggesting a genetically controlled neural circuitry for regulating human social behavior. Expand
Williams syndrome: Findings from an integrated program of research
A dual cannula having two adjoining tubes, a leader tube and a follower tube, in staggered arrangement so as to form two separate and distinct passageways for the withdrawal and return of blood to aExpand
Prevalence of psychiatric disorders in 4 to 16‐year‐olds with Williams syndrome
The prevalence of a range of DSM‐IV psychiatric disorders in a sample of 119 4–16‐year‐old children with Williams syndrome was assessed using a structured diagnostic interview with their parents, finding a significant shift in Predominant Type of ADHD as a function of CA. Expand
