The clinical framework

Téra is not a wellness app. Every signal it tracks has a clinical reason.

Tera observes four behavioural dimensions that may reveal meaningful changes in maternal wellbeing over time. Here is what we measure and why.

Four signals. One picture.

Response Latency

How quickly she places a tile after seeing it. How long she hesitates before responding. How her response time shifts from her own personal rhythm.

Relevant to mood and affect shifts.

Engagement Trajectory

Whether she's drifting toward easier puzzles than she used to choose, or switching between patterns more than usual. A quiet pulling-back from challenge.

Relevant to interest and engagement changes.

Error Recovery

Whether she gives up mid-pattern. How many hints she uses. Whether she's playing at a level below her own personal best, even after reaching it before.

Relevant to coping and persistence patterns.

Session Consistency

How regularly she opens Téra each day. Whether her rhythm is steady or fragmented. Whether she's playing at 3am instead of noon.

Relevant to rhythm, sleep, and withdrawal patterns.

Personal baselines, not population averages.

Most behavioural monitoring tools compare a person to a population norm. Téra does not. Every mother builds her own personal baseline during month 7 of pregnancy, before any postpartum hormonal shift occurs. After delivery, the system recalibrates for two weeks. From that point, every session is measured against her own prior behaviour.

This means Téra is more likely to detect meaningful change in a woman who naturally plays slowly, or one who naturally plays at odd hours, without misreading her baseline as a concern.

The evidence base.

The validation programme is ongoing. Pilot deployments are generating the outcomes data that will form the published evidence base. Results will be published as they become available.
