Nelissen, Jo M. C. – Education and Society, 2021
In this article, it is argued that it makes sense to define and distinguish three levels of human intelligence: intelligence as genotypical potential, intelligence as actualised in environmental interaction, and intelligence as measured by tests (IQ). This raises the questions of what is meant by the term "intelligence as potential", and…

Horobin, Karen D. – 1997
Four studies investigated children's explanations for family resemblance and species-typical characteristics, under different conditions of biological parentage and rearing environment. Participating were 226 children between 3 and 11 years. Children Children were presented with a number of different tasks, some involving people and some domestic…

Fulker, David W.; Cherny, Stacey S. – Population Research and Policy Review, 1995
Describes a methodology of behavior genetics in the context of twin and sibling/adoption design. This model was applied to cross-sectional data on cognitive development throughout the lifespan. Results from a twin and adoption study of general intelligence are presented to illustrate the use of the basic behavior genetic model in studying causes…

Horobin, Karen D. – 1997
This study examining children's understanding of biological inheritance addressed four central questions: (1) are young children able to distinguish between the relative influences of nature and nurture in their understanding of how physical characteristics versus behaviors and preferences develop in animals? (2) does children's understanding of…

Castles, Anne; Datta, Helen; Gayan, Javier; Olson, Richard K. – Journal of Experimental Child Psychology, 1999
Examined heritability of reading deficits in dyslexic subtypes. Found reading deficits were heritable in developmental phonological and surface dyslexics, with greater genetic contribution in the former. Findings suggest a partial independence in the development of cognitive processes involved in reading, and affirm accounts of surface dyslexia…

Caron, Jackie – 1994
Fragile X syndrome is the most common cause of mental retardation next to Down syndrome. The syndrome is more prevalent in males because they only have one X chromosome, where the gene for fragile X is carried, while women have two X chromosomes and the normal gene can compensate for the affected chromosome. Certain physical features are…

Seaver, Judith W. – 1972
This paper examines evidence supporting the hypothesis that environment differentially affects intelligence in a sex-specific manner. The current position that environment and heredity contribute interactively to intelligence obscures the greater vulnerability and exposure of males to environmental influences and the reciprocal lack of equivalent…

Jackson, Jacquelyne Faye – Child Development, 1993
Key components of human behavioral genetics and Sandra Scarr's work of the past two decades are critically reviewed based on scholarship in animal neuropsychology and clinical and educational psychology. Scarr's opinion that interventions to enhance intellectual development are ineffectual for children from abuse- and neglect-free backgrounds is…

Baumrind, Diana – Child Development, 1993
Takes the position, contrary to that of Sandra Scarr, that the details of socialization patterns are crucial to an understanding of normal and deviant development. Research is cited to support the argument that better than adequate parenting optimizes the development of both normal and vulnerable children and that parents' belief in their own…

Bailey, Don; Hatton, Deborah – 2001
This final report reviews the second phase of a life-span study of boys with fragile X syndrome (FSX), the most common known inherited cause of mental retardation. Males with the syndrome are more severely affected than females and in males, delays are usually evident in all the developmental domains, although cognitive and communication skills…
