Mastery Motivation in Children with Intellectual Disability: Is there Evidence for a Down Syndrome Behavioural Phenotype? [PDF]
International Journal of Disability Development and Education, 2015 The main purpose of the current study was to provide empirical evidence to support or refute assumptions of phenotypic deficits in motivation for children with Down syndrome. Children with moderate intellectual disability associated with etiologies other

Behavioural phenotyping of mouse mutants
Behavioural Brain Research, 2001Behavioural phenotyping of mouse mutants is not a goal in itself but serves to characterise the behavioural effects of naturally occurring or experimentally induced mutations. Genetically engineered mouse mutants are valuable tools to elucidate the genetic control of behaviour and the interaction between genetic and environmental factors.

Behaviour phenotype for Down's syndrome
British Journal of Psychiatry, 1998BackgroundFor more than a century, the idea of particular personality/behavioural characteristics being associated with people with Down's syndrome has been explored, but with inconclusive results.MethodThe Disability Assessment Schedule was used to ascertain the behavioural profiles of 360 adults with Down's syndrome and 1829 adults with learning ...

Recent developments in the study of behaviour phenotypes
Australia and New Zealand Journal of Developmental Disabilities, 1994This paper discusses issues arising from studies of the particular behavioural and psychopathological traits associated with genetic intellectual disability syndromes. These traits constitute what are now called behavioural phenotypes. The mechanism of inheritance of the Fragile X gene has now been demonstrated, and behavioural correlates identified ...

Abstract This chapter describes the concept of behavioural phenotypes with examples of genetically-determined neurodevelopmental syndromes which are associated with particular developmental trajectories and specific comorbid risks for challenging behaviour or mental ill-health. Potential neural and other mechanisms that might explain the

The heterozygous reeler mouse: behavioural phenotype
Behavioural Brain Research, 2004The aim of this study was to investigate whether heterozygous reeler mice (+/rl) could be used as a genetic mouse model of schizophrenia, as previously suggested [J. Med. Chem. 44 (2001) 477]. The behavioural phenotype of male and female +/rl mice (young adult: 50-70 days old, and fully adult: >75 days old) was compared to their wild type ...

Bear-hybrids: behaviour and phenotype
Der Zoologische Garten, 2009Zusammenfassung Das Verhalten und die morphologischen Merkmale eines weiblichen und eines mannlichen Barenhybriden (Braunbar Ursus arctos x Eisbar Ursus maritimus) wurden untersucht und mit dem ethologischen Profil und der Morphologie der Eltern verglichen. Die Verhaltensbeobachtungen wurden zwischen Juli und November 2007 durchgefuhrt.

Behavioural phenotypes in adulthood
Psychiatry, 2006Abstract Behavioural phenotypes are syndromes with a chromosomal or genetic aetiology, comprising both physiological and behaviour manifestations, including a distinctive social, linguistic, cognitive and motor profile. The course of the syndrome, both behaviourally and medically, is not stagnant, and the presentation of the syndrome can vary ...

Behavioural phenotypes and mental disorders
Psychiatry, 2009Abstract Genetic disorders account for a sizeable proportion of learning disabilities. Several disorders are associated with mental ill-health. The commonest examples of psychiatric morbidity include psychosis, depression and dementia. Here, three examples of chromosomal abnormalities that have significant research evidence are used to discuss the ...
