The psychological development of an individual involves complex interactions between biological, psychological and social factors. In this area of study students explore how these factors influence different aspects of a person’s psychological development. They consider the interactive nature of hereditary and environmental factors and investigate specific factors that may lead to development of typical or atypical psychological development in individuals, including a person’s emotional, cognitive and social development and the development of psychological disorders.
On completion of this unit the student should be able to identify the varying influences of nature and nurture on a person’s psychological development, and explain different factors that may lead to typical or atypical psychological development.
The complexity of psychological development
the interactive nature of hereditary and environmental factors on a person’s psychological development, illustrated through twin and adoption studies
the role of critical and sensitive periods in a person’s psychological development
the importance of attachment on an individual’s emotional development: genetics; temperament and early life experiences (with reference to the work of Harlow & Ainsworth)
the development of cognitive abilities from concrete to symbolic thinking (with reference to the work of Piaget)
psychosocial development across the lifespan as an influence on the development of an individual’s personality (with reference to the work of Erikson).
Atypical psychological development
the conceptualisation of normality including typical and atypical behaviours; adaptive and maladaptive behaviours; and mental health and mental disorder as a continuum
mental health as a product of internal and external factors which assist individuals to cope with change and challenge
major categories of psychological disorder: addiction disorders; anxiety disorders; mood disorders; personality disorders; and psychotic disorders
the ‘two-hit’ hypothesis as an explanation for the development of particular psychological disorders, illustrated by schizophrenia.
