Pleasure Lifescape Theory (PLT)

The Pleasure Lifescape Theory (PLT) proposes a four-layer developmental–mechanistic architecture of human pleasure (PL1–PL4). Across development, this architecture can undergo pruning, narrowing, monopleasure consolidation, and collapse via three primary pathways—pain-led, shame-led, and self-disconnect–led—with burnout as a prototypical manifestation of the latter. PLT integrates hedonic neuroscience, attachment theory, and emotion regulation science to explain dissociated hedonic profiles and introduces a reconstructive therapeutic framework (Pleasure Lifescape Reconstruction Therapy; PLRT). This v2 update renames the framework as Pleasure Lifescape Theory (PLT), refines key constructs (PL1–PL4), strengthens the distinction between shame-led and self-disconnect-led pathways, expands its integration with DSR, adds testable predictions, and improves overall clarity and consistency.
