It is undoubtedly evident that the field of psychology is becoming increasingly reliant on genetic explanations of human behaviour. It’s undisputable power and potential that it holds for the study offers exciting new developments on levels and quantity that many other sciences can simply not match; yet this over reliance on genetic explanations has caused many issues within the field of developmental psychology, where environmental issues are being ignored completely.
Perhaps up until only a few years ago, developmental psychology has been untouched by the era of genetics. While other fields around it grew and adapted to the scientific principle, developmental psychology was still heavily reliant on environmental influences. The rejection of genetic explanations was primarily due to its lack of insight it could provide for the field. Now however, it is becoming worryingly only reliant on this field of thought as genetic advancements increase at an alarming rate. There is no doubt that genetics can provide answers, it would be foolish to dispute in the face of such hard-hitting evidence.
If any area of research is going to hold a genetic basis, facial recognition in children is going to. It is the beginnings of attachment, the basis of social interaction and is vital for infant and caregiver interaction. Therefore it would be obvious that such a skill would have the possibilities to be innate, however new research suggest that this it is also genetic. After Thomas’ researched the theory, he suggested that even with all other variables taken into consideration, there is unlikely to be any variation let to attribute to no familial environment rendering face recognition ability essentially all genetic. It’s not just the ‘normal’ ability of face recognition that is genetic, but also the abnormal. Research has shown that face perception disorders such as Prospaginoisa have both relatively high concordance rate and pattern of running in families. While Thomas and others attribute genetics as the sole driving force for face recognition, consequently rendering any psychological studies into environmental factors useless, abnormalities in the topic do not. Instead while they do suggest that genetics does play a role, often an environmental influence is required alongside to produce these various disorders.
One of the largest areas of research in developmental psychology is personality acquisition. Of course being such a large topic, there are multiple research proposals behind the genetic basis of personality. Twin studies have been a traditional and fruitful source of quantitative data for the study of genes. Through the analysis of shared and non-shared genes and environment conclusions can be drawn about just how much genetics plays a role in personality. Bouchard was one of the first to suggest a genetic basis. He argued that there was a large body of evidence that supports that individual differences in most, if not all, reliably measured...
