The Fujiwara Lab studies two connected areas. The first is social identity, particularly in gender and neurodiversity. We ask what these mean psychologically, how they shape people's experiences and well-being across different contexts, and what happens when identities conflict (e.g., in sexual-/gender-diverse people).

The second area centres on alexithymia, a personality trait involving difficulty identifying and describing one's own emotions. This includes multiple angles: psychometric work on interactions of alexithymia with personality and well-being, and behavioural studies to probe how it shapes cognition and perception.
