Resumen
Los modelos neuropsicológicos pueden no explicar los trastornos genéticos del desarrollo. Los bebés con síndrome de Williams muestran un desarrollo cognitivo distinto, mejorando en el lenguaje pero disminuyendo en numerosidad con el tiempo.
Área de la Ciencia:
- Psicología del desarrollo psicología del desarrollo.
- La neurociencia es la neurociencia.
- Genética La genética.
Sus antecedentes:
- Los modelos neuropsicológicos de adultos a menudo se aplican para comprender los trastornos genéticos del desarrollo.
- Los modelos existentes asumen que los perfiles cognitivos en la infancia o la edad adulta reflejan los estados infantiles iniciales, con módulos que están intactos o deteriorados desde el nacimiento.
Objetivo del estudio:
- Desafiar la aplicación de modelos neuropsicológicos adultos a los trastornos genéticos del desarrollo.
- Investigar las trayectorias de desarrollo de las habilidades cognitivas en bebés con síndrome de Williams.
Principales métodos:
- Se realizaron dos experimentos con bebés diagnosticados con el síndrome de Williams.
- Las evaluaciones cognitivas se centraron en los juicios de numeridad y las habilidades lingüísticas en diferentes etapas de desarrollo.
Principales resultados:
- Se observó una doble disociación dentro del síndrome en el síndrome de Williams.
- Los bebés se desempeñaron bien en tareas de numerosidad en la infancia, pero disminuyeron en la edad adulta.
- Por el contrario, las habilidades lingüísticas eran pobres en la infancia, pero mejoraron en la edad adulta.
Conclusiones:
- Las trayectorias de desarrollo en los trastornos genéticos pueden ser complejas y no necesariamente se alinean con los modelos adultos.
- Los hallazgos sugieren una interacción dinámica del desarrollo cognitivo, desafiando las suposiciones de modularidad innata estática.
- Los resultados pueden requerir una reevaluación de los enfoques teóricos y clínicos para estudiar los trastornos genéticos.

Overview
Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
Genomic Imprinting and Inheritance
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
