What the corpus is missing

Known gaps

1. Long-duration exposure

   Very high priority · Exposure duration

   Short lab exposures dominate many sensory and cognitive literatures

   next action:Search hours, days, longitudinal occupancy and adaptation studies

2. Hospitality environments

   Very high priority · Applied domain

   Hotels combine sleep, restoration, multisensory experience and service context but are underrepresented as a distinct evidence domain

   next action:Build hotel, resort, guest-room and hospitality-wellness subcorpus

3. Sleep-supportive architecture

   Very high priority · Integration

   Sleep research is often exposure-specific rather than spatially integrated

   next action:Combine thermal, air, acoustic, light and bed-microclimate evidence

4. Neurodiversity

   Very high priority · Population

   Sensory response is often treated as population-average

   next action:Search autism, ADHD, sensory processing, migraine and sensory sensitivity by environmental variable

5. Combined exposures

   Very high priority · Integration

   Real spaces expose people to light, air, thermal, acoustic and visual conditions simultaneously

   next action:Prioritize factorial, multimodal and real-building studies

6. Real environments versus VR

   High priority · Methodological

   Many neuroarchitecture studies use images or VR; real-space replication is thinner

   next action:Run parallel search for field experiments and real-room crossover studies

7. Children + aging

   High priority · Population

   Developmental and age-related differences can change sensory and spatial response

   next action:Create lifespan tags and targeted searches

8. Cross-cultural response

   High priority · Population / culture

   Preference and environmental interpretation can vary by cultural context

   next action:Tag study geography and search replication across cultures

9. Materials beyond wood

   High priority · Materials

   Wood has a growing evidence base; stone, clay, metal, textile and composite research is far thinner

   next action:Search material perception, haptics, thermal touch and associative meaning

10. Olfaction in built settings

    High priority · Multisensory

    Olfaction has strong memory and affect mechanisms but fewer architectural field studies

    next action:Separate mechanism literature from applied environmental scent research

11. Social neuroarchitecture

    High priority · Social

    Layout changes encounter, gaze, privacy and social behavior, but neural evidence is still sparse

    next action:Search social neuroscience with proxemics, visibility and spatial layout

12. Null results + publication bias

    High priority · Evidence quality

    A corpus built only from positive design findings will overstate effects

    next action:Search null effects, replications, registered reports and meta-analytic heterogeneity

13. Dose and thresholds

    High priority · Measurement

    Many design claims ignore how much exposure is needed

    next action:Extract dose, duration, intensity and response curve wherever available

14. Behavior beyond preference

    High priority · Outcome

    Preference is common, but behavior, learning, sleep, error, social interaction and health matter more for practice

    next action:Prioritize objective behavioral and physiological outcomes

15. Individual control

    High priority · Moderator

    Environmental control can modify response to the same physical exposure

    next action:Tag operability, choice, personalization and adaptive opportunity
