Key Points

To establish a cryptographically frozen research protocol evaluating how climbing belay professionals assess lead-fall catches using paired video clips.
Short video recordings of lead-fall catches will be presented in pairs to professional climbing belayers.
Research questions, hypotheses, video stimuli, experimental design, and statistical analyses were predefined and sealed prior to data collection.
The preregistration document was secured using an SHA-256 cryptographic hash (f427d24eae9746908be02f7f8f4a3e50430a260559bc042927378be2035f7bd1).
Empirical findings are not reported in this protocol document, which remains sealed until final outcomes are published.
Data collection and formal analyses will adhere strictly to the frozen pre-specified parameters upon study completion.

Implication

Study preregistration outlines pairwise video evaluations of lead-fall catches in climbing belay professionals, highlighting protocol standardization before data collection.

Abstract

Preregistration of a study on how climbing belay professionals judge lead-fall catches from short videos, shown in pairs. The document fixes the question, the predictions, the video items, the design and the analysis before any data were collected. Sealed until the results are published.
