This review critically examines the research findings which characterize the cognitive, behavioral, and neuroanatomical features of Williams syndrome (WS). This article analyzes 178 published studies in the WS literature covering the following areas: 1) General intelligence, 2) Language skills, 3) Visuospatial and face processing skills, 4) Behavior patterns and hypersociability, 5) Musical abilities, and 6) Brain structure and function. We identify methodological issues relating to small… 

Williams syndrome and its cognitive profile: the importance of eye movements.

People with Williams syndrome (WS), a rare neurodevelopmental disorder that is caused by a deletion on the long arm of chromosome 7, often show an uneven cognitive profile with participants

Williams syndrome and its cognitive profile: the importance of eye movements

Although more research on eye movements in WS is required, the importance of eye movements for cognitive development suggests a possible intervention pathway to improve cognitive abilities in this population.

Williams syndrome-specific neuroanatomical profile and its associations with behavioral features

Social Brain Development in Williams Syndrome: The Current Status and Directions for Future Research

This article discusses how distinctive social behaviors in WS may be associated with alterations or delays in the cortical representation of faces, connectivity within the ventral stream, structure and function of the amygdala and how long- and short-range connections develop within the brain.

Variability and standardized test profiles in typically developing children and children with Williams Syndrome.

There was significantly less variability in younger WS participants for performance scores on Pattern Construction compared to the TD group, and methodological issues and the importance of taking CA into account in analyses will be discussed.

NeuroImage: Clinical Williams syndrome-speci fi c neuroanatomical pro fi le and its associations with behavioral features

The results imply that the unique behaviors in WS were mediated through the constellation of abnormalities in cortical-subcortical circuitry consistent in child WS and adult WS.

Williams syndrome: on the role of intellectual abilities in anxiety

Using ordinal logistic regression analyses, it is shown that decreasing intelligence quotient (IQ) and age are associated with elevated anxiety and low IQ was associated with higher risk of having an anxiety diagnosis.

Relationship Between Brain Abnormalities and Cognitive Profile in Williams Syndrome

Previous studies have shown inconsistent results when reporting brain abnormalities in Williams syndrome (WS). This makes an interpretation of clinical and behavioural data uncertain in terms of



Neuropsychological, neurological, and neuroanatomical profile of Williams syndrome.

A dissociation between language and cognitive functions in Williams syndrome adolescents, in contrast to age- and IQ-matched Down syndrome adolescents is reported, indicating an unusual fractionation of higher cortical functioning, with marked cognitive deficits, but selective sparing of syntax.

I. The Neurocognitive Profile of Williams Syndrome: A Complex Pattern of Strengths and Weaknesses

The rare, genetically based disorder, Williams syndrome (WMS), produces a constellation of distinctive cognitive, neuroanatomical, and electrophysiological features which we explore through the

Analysis of cerebral shape in Williams syndrome.

Subjects with WMS have significantly different cerebral shape from normal controls, perhaps due to decreased parieto-occipital lobe volumes relative to frontal regions and similar observation in the corpus callosum may be associated with a decreased size of the splenium in WMS.

Hypothesis for development of a behavioral phenotype in Williams syndrome.

Theoretical constructs from developmental behavioral genetics, attachment theory, operant conditioning, neuropsychology, and psychosocial theory considered interactively offer explanations for the characteristic behavioral phenotype of 6 factors of Williams syndrome.

Williams Syndrome: Neuropsychological Findings and Implications for Practice

Williams syndrome (WS) is a genetic disorder resulting from a deletion on Chromosome 7. Individuals with WS exhibit distinct physical features such as facial abnormalities, hypercalcemia, and

Language, communication, and neural systems in Williams syndrome

The special characteristics of Williams syndrome provide an opportunity to challenge and develop theories of cognition and forge links between specific neuropsychological, neuroanatomical, and genetic underpinnings relevant to developmental cognitive neuroscience.

An Experiment of Nature: Brain Anatomy Parallels Cognition and Behavior in Williams Syndrome

Findings point to specific neuroanatomical correlates for the unique topography of cognitive and behavioral features associated with this disorder.

Cognitive, adaptive, and behavioral characteristics of Williams syndrome.

A variety of cognitive, adaptive, and behavioral patterns have been shown to be possible in Williams syndrome; therefore, a single predictable cognitive or behavioral phenotype cannot be assumed.

Characterizing the Musical Phenotype in Individuals With Williams Syndrome

Compared to all other groups including the controls, the WS individuals displayed greater emotional responses to music, manifested interest in music at an earlier age, and spent more hours per week listening to music.
