Genetic influences seem to be the most prominent factor after continuity in general cognitive ability. Shared environmental influences are not only responsible for stability but also change in the development of cognitive abilities as well. Bartels et al. (2002) showed significant heritability at all ages, with the predicted increment of genetic stimuli and the reduction of shared environmental stimuli throughout the years.

The heritability of intelligence increases about 60% from infancy to later adulthood. Plomin and Deary (2014) suggested that intelligence captures genetic effects on diverse cognitive and learning abilities, which correlate phenotypically about 30% on average but correlate genetically about 60% or more. Intelligence is

predetermined genetic makeup or environmental influences. Theorists supporting the nature argument see intelligence as being tied to genetic makeup, we are born with our intelligence because it is inherited, whereas, the nurture stance does acknowledge a biological component but supports the idea that intelligence is derived from an individual’s environment, specifically their experiences and socialization (Siegel, 2014).

Nature vs Nurture Essays

Does nature or nurture play a greater role in development? One of the most debated and argued subjects in psychology is the nature versus nurture debate.
