Latency recording tool

How to use this tool

Use this latency recording sheet to understand elapsed time from a defined cue to an observed response.

• Define the cue, response and observation limit for a fictional series.
• Record each opportunity as a response observed, no response within the limit or a missing observation.
• Enter elapsed times in the displayed unit and review observed responses separately from time-limited records.

Fictional example and how to read the result

A response at 4 seconds is an observed latency. No response during a 10-second limit is a censored observation, not an observed 10-second response.

The report keeps response times and observation limits distinct. It cannot identify the cause of a delay or recommend an intervention.

Latency measures the delay before a response begins

Define the cue and first observable response movement or sound before recording. Latency concerns the delay before response onset; duration concerns how long a response lasts.

A response not seen before the observation limit is right-censored: the limit is not an exact latency and is never entered as zero. No-response and not-observed counts remain separate from observed-response summaries.

The mean, median and range describe observed responses only. With no-response windows they can underrepresent the full waiting experience; review those records alongside the summaries.

• Use one unit and one cue/response definition throughout a sheet.
• Observed zero is valid when response onset coincides with the cue.
• Enter the actual observation limit for a no-response window.
• Start a new dataset when timing units or cue/support conditions change. This is an entered-time recorder, not a live browser timer.

What to enter in each field

• Defined cue / starting event: Define the visible or audible event that starts timing, such as placing an agreed picture on the table. This is entered-time recording, not a browser timer.
• Observable response-start rule: Define the first observable movement or sound that stops timing. Latency is the delay before this response begins, not its duration.
• Elapsed-time unit: Choose one unit for both elapsed times and observation limits. Changing the label does not convert existing numbers; convert deliberately or start a separate sheet.
• Observation context and allowed supports: Describe the common setting, materials and allowed supports. Use a separate sheet if cue, response or support definitions change.
• Observation ID: Use an anonymous label for one cue/response observation, such as A. Keep its elapsed time, status and limit together.
• Response status: Observed: a response started and elapsed time was measured. No-response: no start before a known limit. Not-observed: missing or interrupted observation. The latter two are not zero latencies.
• Observed elapsed time: Enter the measured delay in the selected unit for observed responses. Zero is valid if onset coincides with the cue. Leave blank for no-response and not-observed.
• Observation limit: Enter the positive maximum observation time in the selected unit; required for no-response. It is a limit, not an exact response time. An observed delay cannot exceed an entered limit.
• Context / support: Optional: record actual supports or context anonymously so unlike observations are not mistaken for comparable ones.
• Anonymous observation note: Optional: explain a limit, interruption or missing observation without personal identifiers.
