Self-Grooming Scorer

Score grooming time percent, mean bout length, cephalocaudal sequences, group SEM, and CSV export for repetitive-behavior studies.

Self-grooming scoring table

Enter total grooming duration, bout count, and cephalocaudal sequence counts for each animal. The scorer reports grooming time percent, mean bout length, and sequence count summaries by group.

Group grooming time

Group mean bout length

Group sequence count

  • Compute grooming time percent from scored video or live observation
  • Calculate mean grooming bout length
  • Track cephalocaudal sequence counts as a patterning readout
  • Compare autism-model and control cohorts with group SEM
  • Export animal-level grooming rows for downstream analysis

Don't use for

  • Full ethogram scoring with many non-grooming behaviors
  • Three-chamber social approach data
  • Automated pose-estimation outputs that already include validated grooming classifications

Resources

  • Session duration fixed within cohort
  • Arena novelty and acclimation matched across groups
  • Bout split rule defined before scoring
  • Cephalocaudal sequence definition written down
  • Age, sex, strain, and circadian timing documented
  • Scorer blinded to treatment or genotype when possible

Self-Grooming as a Repetitive Behavior Readout

Rodent self-grooming can be scored as total duration, bout structure, and ordered cephalocaudal sequences. In autism-relevant phenotyping, elevated grooming is often interpreted as repetitive or stereotyped behavior when protocol context supports that interpretation.

Metrics and Math

Grooming time percent is total grooming duration divided by session duration x 100. Mean bout length is grooming duration divided by bout count. Sequence counts are reported as raw event counts and summarized by group.

Design Notes

Use fixed scoring windows, matched arena novelty, consistent bedding or floor surface, and blinded observers. Report strain, age, sex, lighting, acclimation, and whether grooming was manually scored or video assisted.
