Contextual Cues & Retrieval outline
Retrieval depends on cues matching encoding context; behaviour emerges when environmental or internal cues reinstate the bindings that were active during learning.
Memory isn't stored in a filing cabinet waiting to be retrieved on demand. It's reconstructed from cues that match how it was originally encoded. Walk into the room where you learned something and the memory surfaces more easily. Return to the emotional state you were in and details flood back. Sit in the same chair, smell the same smell, hear the same background music, and suddenly the intended action or thought pops into mind unbidden. This is encoding specificity: recall succeeds when cues overlap with the context in which the neural pathways were originally trained.
The reason this matters is that behaviour is context-dependent by design. If you practise a new routine in your office but need it at home, don't be surprised when the old habit runs instead---the home cues weren't part of the training context, so they don't retrieve the new pathway. The brain is an adaptive system responding to environmental regularities. When the context reinstates the bindings that were active during encoding, the associated behaviour follows automatically. This is why "I'll just remember to do it differently" so often fails: you're relying on retrieval without the cues that would actually trigger it.
Context includes environmental features (location, objects, sounds) but also internal states (mood, arousal, bodily sensations). State-dependent learning means you're more likely to retrieve what you encoded in a similar physiological state. Practise the calm response while calm, and it may not be available when you're stressed---stress is a different context, and the pathway hasn't been trained there. To make a behaviour reliable across contexts, you need to either practise it in all the contexts where you'll need it, or design strong environmental cues that work across states.
This architecture also explains why reconstruction is so malleable: if the current cues don't perfectly match encoding, the system fills gaps with whatever fits the active task-set or current model. The practical lever is deliberate cue design: build environmental or procedural cues into the exact context where you want a particular routine or memory to surface, and let the retrieval process do the work for you.

Ways to think with this
Practical ways to use this neural mechanism in understanding behaviour
WIP: Context reinstates predictions
Retrieval depends on cues matching encoding context. When contextual cues overlap with how a pathway was originally trained, the associated predictions and behaviours load automatically. This is why walking into a room can trigger a memory or why returning to an emotional state brings details flooding back---the cues reinstate the bindings that were active during encoding.
So what can you do? Design cues deliberately. If you want a behaviour to run reliably, build environmental or procedural cues into the context where you need it. And if you practise something in one context but need it in another, don't expect automatic transfer---the new context lacks the retrieval cues. Either practise in all the contexts where you'll need it, or create strong cues that work across settings.
WIP: Cues bind features into patterns
Context determines which features get bound together during encoding, and those same contextual cues drive retrieval. Change the context and different patterns surface because different cues reinstate different bindings. This is why state-dependent learning works: you're more likely to retrieve what you encoded in a similar physiological or environmental state.
So what can you do? Match retrieval context to encoding context when reliability matters. If you need a behaviour available under stress, practise it while stressed---stress is a context, and the pathway needs to be trained there. And when you want insight or flexibility, vary the context during practice so the bindings aren't too tightly coupled to one specific set of cues.
WIP: Let cues do the triggering
Behaviour emerges when cues reinstate the pathways that were active during learning. This means you don't have to rely on willpower or explicit recall---if the cues are right, retrieval happens automatically. But it also means that "I'll just remember to do it differently" usually fails because you're relying on retrieval without the cues that would actually trigger it.
So what can you do? Don't rely on remembering. Instead, build cues into the environment or the routine itself so the right pathway loads when the context appears. The brain is an adaptive system responding to environmental regularities---use that. Design the context to trigger the behaviour you want, and let the retrieval process run automatically.
