cognitive neuroscience ao1 + ao3

what is cognitive neuroscience

• aims to explore neurobiological basis of thought processes and psychological disorders

• combines ideas from cognitive psychology and neuroscience

why has cognitive neuroscience developed rapidly

• advances in brain imaging technologies such as fMRI and PET scans

strengths of cognitive neuroscience

• practical applications

• provides evidence for interaction between biological factors and environmental experiences

weaknesses of cognitive neuroscience

• ethical concerns

strength - practical application

• can identify cognitive difficulties before observable behaviours appear

• fMRI and PET allow researchers to examine patterns of brain activity linked to cognitive processes (ASD may now be detected in infants as young as 3 months old)

• allows intervention sooner, can improve communication, social development and learning outcomes

• improve psychological wellbeing

strength - evidence

• provides evidence for interaction between biological factors and environmental experiences

• neuroplasticity research shows brain can change (experiences, learning skills etc)

• biology does not completely determine behaviour. experiences influence it

• demonstrates nature and nurture can work together

weakness - ethics

• developments in brain imaging technology raise ethical concerns

• fMRI may be used for lie detection in legal settings like courts

• may reveal thoughts/info individuals don’t want to share

• strict ethical guidelines needed to prevent misuse of this technology
