DESCRIPTION:Is adolescent behaviour primarily driven by an exaggerated res
 ponsiveness to rewarding outcomes? Do adolescents take more risks due to d
 ifficulty in avoiding harm? How did they respond to a global threat like t
 he Covid-19 pandemic? These are the questions which will be explored in th
 is presentation\, where together we will embark on a journey through the b
 rain regions critical for regulating appropriate approach-avoidance behavi
 ours\, and observing how they evolve during development. The focus will ce
 ntre on translational tasks utilised in our laboratory\, along with EEG\, 
 including Pavlovian fear conditioning\, extinction\, and active and passiv
 e avoidance paradigms. I will share key findings from our research\, revea
 ling significant differences between adolescents and adults in their capac
 ity to enhance early visual processing when exposed to learned danger sign
 als. Furthermore\, I will endeavour to integrate and discuss the implicati
 ons of these findings. This involves challenging the prevailing notion tha
 t adolescents are less motivated or less capable of learning from negative
  outcomes. I will also discuss how our research influences current neurobi
 ological models of adolescence\, shedding light on this crucial phase of d
 evelopment. Additionally\, I will explore how our findings shed light on w
 hy some adolescents are more vulnerable to experiencing reduced well-being
  and an increased likelihood of developing mental health disorders.
