However, it is difficult to disentangle possible genetic factors from a parent's attitude or use of language, for example. [4] A child's ordinal position in their family has also been shown to affect intelligence. A number of studies have indicated that as birth order increases IQ decreases with first borns having especially superior intelligence.
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason.
Through social behavior, humans have developed society and culture distinct from other animals. [10] Human social behavior is governed by a combination of biological factors that affect all humans and cultural factors that change depending on upbringing and societal norms. [11]
Health can affect intelligence in various ways. Conversely, intelligence can affect health.Health effects on intelligence have been described as being among the most important factors in the origins of human group differences in IQ test scores and other measures of cognitive ability. [1]
Human intelligence is the intellectual power of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. [ 23 ] [ 24 ] Intelligence enables humans to remember descriptions of things and use those descriptions in future behaviors.
Fundamental attribution error, the tendency for people to overemphasize personality-based explanations for behaviors observed in others while under-emphasizing the role and power of situational influences on the same behavior [116] (see also actor-observer bias, group attribution error, positivity effect, and negativity effect).
In the study of malleable intelligence, behavioral factors are often the most intriguing because these are factors humans can seek to control. There are numerous behavioral factors that affect intellectual development and neural plasticity. The key is plasticity, which is caused by experience-driven electrical activation of neurons.
A large amount of research in this area has been focused on the neural basis of human intelligence. Historic approaches to studying the neuroscience of intelligence consisted of correlating external head parameters, for example head circumference, to intelligence. [1] Post-mortem measures of brain weight and brain volume have also been used. [1]
