This work was a true team effort, led by Caroline Lee in my lab with former lab members Samantha Cohen and Sam Hutchinson, in collaboration with Nim Tottenham and her lab!

On the contrary, kids who currently feel strong attachment to their caregivers may be processing these same narratives using a top-down approach where schema regions in the PFC are activated. There are even more results and cool methods in the paper, so check it out!

All in all, we think that kids with unstable caregiving histories may not have learned a stable (or what we would consider “standard”) attachment schema, so they’re activating episodic memory and visual processing regions when watching an attachment narrative.

We also looked at kids' verbal recalls of the movies! Interestingly, we found that recalls in kids who report weaker attachment are more focused on the Searching event in the attachment schema.

Looking at kids’ brain activity related to caregiver stability, we show that kids with unstable caregiver histories have more connectivity between the amygdala and visual processing regions + hippocampus.

Our results show that there are indeed differences in brain responses! Kids who report stronger attachment to their current caregiver(s) have more connectivity between the amygdala and vmPFC. Whole-brain results show that heightened amygdala connectivity also shows up in lateral frontal regions.

We compared brain responses to the movies based on childhood experiences: caregiver stability (caregiver switch/es vs no switch) and caregiver attachment (weak vs strong). We examined response patterns in the amygdala to other regions in the brain with ISFC (Inter-Subject Functional Connectivity).

To understand whether childhood experiences such as changing caregivers (in the past) and attachment security (in the present) impact how kids view attachment narratives in movies, we had kids watch a short movie edited to depict 4 crucial events of an attachment schema while collecting fMRI.
